[0057] As such, references to a feature or aspect are intended to describe a feature or aspect of an example of the Present Disclosure, not to imply that every embodiment thereof must have the described feature or aspect. Furthermore, it should be noted that the description illustrates a number of features. While certain features have been combined together to illustrate potential system designs, those features may also be used in other combinations not expressly disclosed. Thus, the depicted combinations are not intended to be limiting, unless otherwise noted.

[0058] In the embodiments illustrated in the Figures, representations of directions such as up, down, left, right, front and rear, used for explaining the structure and movement of the various elements of the Present Disclosure, are not absolute, but relative. These representations are appropriate when the elements are in the position shown in the Figures. If the description of the position of the elements changes, however, these representations are to be changed accordingly.

[0059] Many embodiments are described herein. For example, such embodiments include but certainly are not limited to: Patch Panel Assemblies with Modular Aspects, an Interconnecting Housing For Network Patch Panel, a Data Jack With Exterior Terminals, a Light Pipe Assembly For Network Patch Panels, a Patch Panel Frame With Module-Receiving Nest, and Circuit Board Modules For Use With Patch Panel Assemblies. General descriptions of these example embodiments follow as an introduction to their more detailed descriptions with reference to the Figures.

[0060] Patch Panel Assemblies with Modular Aspects: An improved patch panel assembly includes a frame and faceplate that mate with a housing, and the housing defines a plurality of individual communication ports. The housing is mounted to the patch panel frame and includes jack openings that accommodate data jacks and circuit board openings that accommodate mating blades of circuit boards. The two sets of openings are separated on the housing by an intervening spacing and interposer terminal sets are provided to electrically interconnect the jacks with circuits on the circuit boards. The patch panel housings may be formed in discrete groupings so that, if desired, the patch panels may have ports that are grouped together by bandwidth, storage capability and the like. Inasmuch as the housings are mounted to the patch panel frames, the jacks and the circuit boards can be easily and individually replaced, repaired or upgraded with similar components without requiring disassembly of the patch panel.

[0061] Interconnecting Housing For Network Patch Panel: A housing for housing and interconnecting components of a patch panel assembly includes a body portion with first openings that are configured to releasably receive data jacks therein, and second opening that are configured to receive mating blades of printed circuit boards. The first and second openings are aligned together in distinct rows so that the first and second openings are spaced apart from each other. In order to interconnect terminals of the data jacks with circuit on the circuit boards, a plurality of conductive terminals are provided and are supported by the housing body portion. The terminals are located between the first and second openings and the terminals include free ends that extend toward the openings so that insertion of the jacks and circuit boards causes the terminal free ends to contact same and electrically interconnect them together.

[0062] Data Jack With Exterior Terminals: An improved telecommunications jack is provided that reduces the time for repair, replacement and upgrading of network patch panel components. The jack includes an exterior metal housing in a configuration dimensioned to fit into a first opening of a housing of the patch panel. The jack housing includes one or more stop surfaces that are engaged by a latch member on the housing which extends into the first opening. The jack has an interior hollow cavity that accommodates a plurality of conductive terminals that mate with a data plug inserted into the jack. A flexible terminal is disposed in the jack cavity and flexes under pressure of an inserted plug to contact another terminal and signal that the plug is inserted. The jack further includes a plurality of terminals that extend outside of the housing and into contact with terminals supported by the patch panel housing.

[0063] Light Pipe Assembly For Network Patch Panels: A light pipe structure particularly useful with network patch panels includes at least one housing that defines a preselected number of communication ports of the panel. The housing has individual openings that receive individual data jacks and a common opening that receives one or more mating blades of a circuit board. Each housing has its board-receiving opening disposed beneath its set of jack openings and channels are provided in the housing that receive and support light pipes. The channels communicate with the broad-receiving openings so that the transmitting ends of the light pipes may confront light-emitting diodes mounted on the circuit boards, when the circuit boards are inserted into the board-receiving openings of the housing. The display ends of the light pipes may be arranged beneath individual panel ports.

[0064] Patch Panel Frame With Module-Receiving Nest: A patch panel assembly has a frame structure that includes a face plate, a base plate, a jack housing and a cable manager. The housing has first openings for jacks and second openings for circuit boards. The second opening are located beneath the first openings so that any one circuit board may be inserted or removed without necessitating removal of the remaining circuit boards. Additionally, the jacks are maintained at a certain level within the patch panel frame as are their associated cables, managed by a cable manager at a similar level above the base plate of the patch panel frame. This difference in elevation defines a nest that accommodates circuit board modules that may be inserted and removed in a pluggable fashion.

[0065] Circuit Board Modules For Use With Patch Panel Assemblies: A patch panel assembly has a frame structure that includes a face plate, a base plate, a jack housing and a cable manager. The housing has first openings for jacks and second openings for circuit boards. The circuit boards are supported within modules that include corresponding engaging cover and base plates that define a modular enclosure. Standoffs support the circuit boards within the modules in an orientation such that they can easily be inserted and/or removed from the patch panel housing second openings.

[0066] FIGS. 1-2 illustrate a patch panel assembly 30 constructed in accordance with the principles of the Present Disclosure having an improved structure which provides beneficial results when used in association with a data communication network. The patch panel assembly 30 includes a patch panel 31 comprising an elongated frame 32 having an associated elongated face plate 33 that extends widthwise along the frame. The panel frame 32 may include, as shown, a rearward extending base plate or portion 34 that defines a floor, or receptacle, which may receive a module assembly 36 therein. The face plate 33 and base plate 34 may be integrally formed together as illustrated, or may be separately formed and joined together in a conventional manner such as by screws, nuts, clips and the like.

[0067] The panel face plate 33 extends in two directions. The face plate 33 includes a front portion 33a that faces outwardly and which has port identifying characteristics such as numbers, symbols and the like, and a top portion 33b bent from the front portion 33a to extend rearwardly therefrom. The top portion 33b may also be considered as a retainer bar, or member, because it includes a plurality of stop surfaces and openings that are configured to engage complimentary shaped engagement members or panel housings 46, noted in more detail to follow.

[0068] A cable manager 40 is provided and it extends widthwise between mounting ends 32a of the patch panel frame 32, which may be bent inwardly, as illustrated, and may be secured thereto by nuts 32b on a mounting bolt 32c, as illustrated. The cable manager 40 is offset toward the rear of the patch panel assembly 30, as shown, and is preferably raised with respect to the panel 32 in order to define a widthwise space through which cables (not shown) connected to the jacks 110 may be run. The cable manager 40 has a serrated end configuration with a plurality of slots 41 formed therein for supporting cables which are terminated to the panel jacks 110. A circuit board module 36 is shown as rectangular in configuration and is provided that at least partially encloses a circuit board 86 associated with a particular section of the patch panel assembly 30. The circuit board module 36 includes a base plate or bottom cover 35, a top plate or cover member 35a and an end plate 37, which cooperatively define a hollow enclosure for the circuit board 86 utilized in assemblies of the Present Disclosure.

[0069] The end plate 37 closes the rear end of the module 36 and further can be configured to define a handle 37a by which a user can easily insert and remove the modules 36 from their position in the panel frame and engagement with the housing circuit board openings 56. The cover plate 35a extends over a portion of the circuit boards 86 utilized in the patch panel assemblies 30 and provides a means to protect the electronic components supported on and connected to the circuit board 86.

[0070] Standoffs 92 in the form of threaded tubes 92a (FIG. 22A) are provided to support the circuit board 86 above the base plate 35 and away from the cover plate 35a and may be used in conjunction with recesses 36b formed therein. Corresponding screws 93 engage the tubes 92a to orient the circuit board 86 properly within the module 36 at a height suitable for reliable engagement with the housings 46. The circuit board leading edge projects outwardly from the interior of the module 36 and it extends between and past the respective leading edges of the base and cover plates, 35, 35a and into alignment and engagement with the circuit board openings 56 of the panel housing 46.

[0071] The circuit board 86 of the patch panel assembly 30 is spaced apart from and above the base plate 34 of the 30, and may include not only electronic components 94a, such as amplifiers, logic gates, controllers and the like, but also one or more connectors 94b supported on the top and/or bottom surface 98 of the circuit board 86. The connectors 94b may extend as shown either vertically or horizontally, and accordingly, the cover plate 35a and end cap 37 are provided with openings or penetrations 35c, 37c that permit the receptacle portions of the connectors 94b to be accessed. As illustrated best in FIGS. 11 and 16, these connectors 94b provide a means to connect to the circuitry of the circuit board 86.

[0072] Although illustrated in the Figures as a single circuit board 86, it will be understood that the structure for the patch panel assemblies of the Present Disclosure will permit the use of multiple circuit boards, depending on the system designer's needs. In such instances, multiple circuit boards may be associated with single or multiple panel housings 46. Such a structure will permit an incremental, “drop-in” expansion with the system operator being able to insert additional circuit boards 86 to increase system capacity or the like, rather than remove and replace a single circuit board. Such multiple circuit boards may be associated with respective single panel housings 46, or they may be associated with a plurality of them such as two, or three, panel housings 46.

[0073] Due to the differences on lengths of the circuit board 86 and the top and bottom covers 35, 35a, the metal cover plate 35 of the module 36 does not cover all the electronic components 94a supported by the circuit board 86, so a protective covering in the form of a Mylar film sheet 95, or a similar film-type covering is provided as a cover as illustrated in FIGS. 14-6. The leading edge 95a of the film sheet may be bent downwardly to define a contact flap 95b interposed between the electronic components 94a of the circuit board 86 and the terminals 63 of the panel housing 46 and so provide a measure of insulation against unintended shorting (FIGS. 10-1 and 24C). The bottom cover plate 35 may include, as shown in FIGS. 22A and 24C′, an upturned stop surface 35b which prevents overtravel of the module 36 during insertion. It is formed by bending the front portion of the bottom cover 35 upwardly in order to confront opposing surfaces of the insulative portions of the panel housings 46. The height of these stop surfaces 35b is chosen to engage (if over-inserted) the insulative body portions of the panel housings 46 rather than contact the conductive terminals 63 supported on the housings 46.

[0074] The cable manager 40 is offset in the vertical direction to define a working space behind it and underneath the slots 41 thereof for cables to run, widthwise. The cable manager 40 is further spaced a preselected height above the panel frame base plate 34 to define a nest 108 within the panel frame 32 that accommodates the module 36. This nest also includes the vertical distance NH between the top surface of the panel frame base plate 35 and the bottoms of the jacks 110 and the bottom of the cable manager support base 40a (FIG. 7). This distance is greater than the height of the circuit board modules 36 and thereby permits the modules 36 to be inserted and removed from the patch panel 31 without interfering or disturbing any of the jacks 110 or any part of the patch panel frame 32. The module 36 fits into the panel frame nest 108 in a sliding manner sliding upon the panel frame base plate 34. The module 36 also preferably includes means by which to engage the panel frame and as shown in the Figures, may include engagement ends 39 which may be integrally formed as side ends of the end cap 37 of the module 36. These engagement ends 39 include hooks 39a defined therein which are oriented lengthwise. They are disposed in opposition to corresponding opposing slots 34a formed in the panel frame base plate 34. The hooks 39a have planar stop surfaces 39b that engage confronting stop surfaces 34b of the base plate openings 34a.

[0075] In order to provide grounding contact, the circuit board modules 36 are also provided with grounding springs 36a that extend lengthwise along the side walls of the panel frame 32. As illustrated in FIG. 23, the grounding springs 36a are elongated and extend lengthwise. They include two portions 36c that bow outwardly and make contact with the panel frame 32 inside walls. These grounding springs 36a will also make contact with each other as between adjacent modules 36. The modules 36 may have side walls along opposite sides thereof as illustrated in FIGS. 1-2 and the rear end caps 37, associated end caps 37a and cable managers 40 extend between the sides. The right side walls, with reference looking forwardly, are not shown in FIGS. 3, 5-6, 11 and 22-3 for clarity.

[0076] The panel frame 32, as shown best in FIG. 2, includes a plurality of openings, shown as rectangular slots 42, which extend widthwise within the face plate 33. These slots are configured to accommodate one or more housings 46, which serve to divide the openings 42 into distinct sets of individual patch panel ports 31a, each of which is configured to receive the plug end of a network cable (not shown). In this regard, the housings 46 may be particularly provided in sizes that define N number of patch panel ports, where N can typically be chosen from the group of 1, 2, 3, 4, 6, 8, 12 or 24. These numbers divide evenly into the standard number of ports in a patch panel, namely twenty-four. As such, if the patch panel face plate 33 is provided with four slot openings 42, the housings 46 that mate with the openings 42 will contain six first openings 55 that will form ports 31a in each slot opening 42. Likewise, six slot openings 42 will accommodate four first openings 55 in each housing 46.

[0077] The face plate 33 may further include a plurality of other ancillary openings, with one type of opening 43 accommodating mounting screws 43a that extend through the face plate and which are received in complementary screw openings formed in the housings 46. Other types of openings 44 may be dedicated as indicator openings which accommodate the output ends of light pipes 102 that display an indication of the status of the port 31a and/or a data transmission channel of the network. Other openings may be present that engage clips which hold a cover plate 38 in place over the housing screws. The face plate top retainer bar 33b extends back from the top of the face plate 33 and includes different openings 61a, 61b that will engage different parts of the housings 46 when the panel components are fully assembled.

[0078] In order to provide the patch panel assemblies 30 of the Present Disclosure with a measure of modularity, which reduces the time for paneling, repairing and assembling patch panels of the Present Disclosure, the face plate slots 42 have predetermined widths which accommodate a preselected number N of ports 31a of the patch panel 31. Housings 46 are provided which engage these slots 42 and the housings 46 not only serve to subdivide the face panel slots 42 into individual patch panel ports 31a, but also provide a structure which accommodates and interconnects the jacks 110 and circuit boards 86 used in the patch panel assemblies 30 together.

[0079] Every housing 46 has a body portion 50, preferably formed from an insulative material. The housing body portion 50 has screw bosses 47 that are threaded and which permit the housing 46 to be attached to the patch panel face plate 33 by way of interengaging screws 48 and nuts 49. A plurality of vertical side walls 52 are supported on the housing body portion 50 and cooperatively define a plurality of hollow, first openings 55 which are configured to receive data jacks 110 therein. A top cross bar 54 extends widthwise and engages portions of the face plate retainer bar 54. Second openings 56 are provided in the housing 46 which accommodate the leading edges 87 of an associated circuit board 86. These second openings 56, as illustrated, extend for the most part horizontally as compared to the vertical directions in which the first openings 55 extend. If imaginary lines 11, 12, were drawn through the centers of the first and second openings, they would intersect each other as illustrated in FIG. 7. The jack openings 55 are aligned along a first common axis A1 which may be taken through the centers thereof, while the circuit board openings 56 may be aligned along a second common axis A2 which is also preferably taken through the centers thereof. These two axes are preferably parallel to the frame base plate 34.

[0080] The second openings 56 may be subdivided into pairs of openings 56a, 56b by means of a divider 58. This divider 58 takes the form of an upright wall and confronts a slot 91 formed in the circuit board mating blade 89 to thereby provide a polarization aspect to the housing and circuit board combination so that a circuit board 86 may be inserted into the second openings 56 in only one (and correct) way. As shown in FIG. 5, grounding clips 46a may be provided for the patch panel housings 46 that extend into the first openings 55 of the housings to establish redundant grounding contact between the panel frame 32, the face plate 33 and the jacks 110.

[0081] The cross bar 54 of the face plate 33 includes different sets of openings 61, with one set, shown as square openings 61a, being configured to receive positioning studs 60 formed on the housing top bar 54. Other, rectangular openings 61b extend in an axial direction (front to back) in order to accommodate latch members 72 of the housing 46. The latch members 72 are cantilevered in their structure to define free ends 73, and they are shown as extending rearwardly in the embodiments discussed herein. If desired, the latch members 72 may be fashioned to extend forwardly. The cantilevered structure of the latch members provides them with sufficient flexibility to selectively engage and disengage the jacks 110. The latch members 72 extend axially within these other openings 61b so that they may be manipulated from either the front of back of the patch panel face plate 33 in order to disengage them from the jacks 110.

[0082] The latch member free ends 73, as shown in FIGS. 9-10, have angled surfaces 74a that permit the latch members 72 to slide up and catches 125 which are preferably formed as part of the front cover 124 of the jack 110 and which are disposed on the top surface of the jack 110. These catches 125 also have angled surfaces 125a as their front surfaces which facilitate the lifting of the latch member free ends 73 over the catches 125. The catches 125 further include rear stop surfaces 125b that are preferably planar surfaces that extend vertically. These rear stop surfaces 125b confront and engage the planar, hook surfaces 74b of the latch member free ends 74 to prevent the jacks 110 from falling out of their position within and engagement with the housings 46. The front faces of the latch members 72 may include a slot 75 or similarly configured element that permits a user to insert a tool, such as a screwdriver, into the patch panel retainer bar other openings 61b and engage the latch member 72. In this manner, the user can lift the latch member 72 up so that the hook surface 74b disengages the jack catches 125 and the jacks 110 may be withdrawn from the housing first openings 55.

[0083] Although the jack catch-latch member hook surface combination provides sufficient retention of the jacks 110 in place in the housing 46, in order to provide additional securement, the housing 46 may further include slots 77 that extend horizontally and which are disposed in the sidewalls 52 of the housing 46. These side wall slots 77 are configured to accommodate opposing locating ribs 133 that are disposed on the sides of the jacks 110 and which are illustrated as projecting outwardly from the jack front cover 124. The interengaging slot 77-locating ribs 133 combination provide a measure of retention to each jack to keep it in engagement with its housing openings 55. Additional structural features of the housings 46 that provide means for locating the jacks 110 in place within the housing 46 include shoulders 76 on the rear surfaces of the housing sidewalls 52. These shoulders 76 confront and engage opposing, vertical stop shoulders 132 that are disposed on the jack front covers 124.

[0084] In order to seat the housings 46 in a preferred orientation within the patch panel slots 42, the housing 46 may include an upraised edge 59 which may either be continuous for the width of the housings 46, or, as illustrated, it may have a discontinuous configuration. The edge 59 bears against the rear edge of the top bar 33b of the panel face plate 33. The housing top edge 59 is also preferably spaced apart from the studs 60 of the housing and the latch members 72 so as to hold, preferably in an interference fit, the end of the face plate retainer bar 33b therebetween. This fit is illustrated at least in FIGS. 10 and 14-5.

[0085] In an important aspect of the Present Disclosure, the housings 46 of the patch panel assemblies 30 are provided with a plurality of conductive terminals 63, which are preferably arranged in distinct terminal sets 62, with each terminal set 62 being associated with one of the housing first openings 55. For each set, the terminals 63 include central retention portions 64 which may include engagement barbs that are flanked by first and second terminal tails, 65 and 66, respectively. The tails 65, 66 extend away from opposite ends of the retention portions 64 in a cantilevered fashion ad extend outwardly away therefrom in an angled fashion such that imaginary lines drawn through the longitudinal axes of the terminal tails 65, 66 will intersect at a location rearwardly of the retention portions 64. In order to provide improved contact, the terminal first tails 65 may include different sized contact pads 65a.

[0086] The terminals 63 are supported by the housings 46 so that they are interposed between circuit in the data jacks 110 and circuits on the circuit board 86. The terminals serve to provide an electrical connection between exterior terminals 138 of the jacks 110 and contact pads 90 of the circuit boards 86. Due to their cantilever and overall bowed configuration, the terminals 63 are in effect, preloaded with a spring force so that they will resist any vertical forces applied to them and ensure reliable contact between the terminals 63 and the opposing elements. In this regard, and as illustrated in FIGS. 10, 13 and 15-7, the terminal first tails 65 are aligned with respective housing first openings 55 and the terminal second tails 66 are aligned with the housing second openings 56 and further extend into the second openings 56.

[0087] The terminals 63 are positioned on the housing 46 firstly in an arrangement so that the second terminal tails 66 extend into the housing second opening 56 and align with corresponding contact pads 90 that are disposed on the top surfaces 96 of the circuit board 86 and which are disposed along the leading edges 87 thereof. The contact pads 90 are further arranged on the mating blades 89 of the circuit board 86, which may be separated from each other by the circuit board leading edge locating slot 91 that engages the housing second opening dividing wall 58. The terminal second tails 66 are preferable curved and the free ends thereof point generally forwardly so that the circuit board contact pads 90 will encounter the contact areas of the second tails 66, particularly the curved contact portions thereof when the mating blades 89 or leading edges 87 of the circuit board is fully inserted into the second openings 56.

[0088] The terminal first tails 65 are formed with a similar configuration and include an elongated curved tail portion with a free end that extends forwardly toward the housing first opening 55. The curved portions of these first tails 65 may include, as illustrated, a series of contact portions 65a that have a width which is wider than most of the first tails 65. These curved contact portions 65a are positioned on the housing 46 in opposition to the exterior terminals 138 of the jacks 110. Their cantilevered structure permits them to flex under contact with the jacks 110 when the jacks are inserted into the housing first openings 55. In order to permit the terminal first tails 65 to fully flex under the pressure of the jacks 110, the housing body portions 50 preferably include longitudinal slots 53 disposed therein in alignment with the first terminals 65. These slots 53 receive the free ends of the terminal first tails 65, which deflect downwardly toward the terminal second ends 66 when the jacks 110 are inserted into the housing first openings. In this manner, the terminals 63 are held in the housing 46, which serves as both a support for the jacks 110 and circuit boards 86 and an interposer connector that electrically connects them together.

[0089] Patch panels often include light pipes for operational status information associated with their ports 31a. The circuit boards 86 utilized in the Present Disclosure have on their bottom surfaces 98, LEDs 100 mounted in supports 101 that support at a preselected level with respect to the circuit board bottom surfaces 98. The LEDs 100 and the light-emitting surfaces thereof are oriented with respect to the circuit board 86 and forwardly with respect to the patch panel 31. The housings 46 may be configured as shown best in FIGS. 10 and 13-4, to support a plurality of light pipes 102 in a preselected association with the ports 31a of the patch panel 31.

[0090] The light pipes 102, as illustrated, have an offset and somewhat S-shaped configuration that extends between two ends, one end being an input end 105 which confronts, and preferably abuts the display faces 100a of the LEDs 100, and the other end being an output end 106. As noted above, the circuit boards 86 are supported in their modules 36 at a level so that the LEDs 100 thereof will abut the light pipe input ends 105 when the circuit board modules 36 are inserted into the panel frame nest 108. The output ends 106 extend into respective associated indicator openings 44 that are disposed in the patch panel face plate 33 in association with a patch panel port. The output end 106 can then communicate with the exterior of the patch panel 30 to identify to an installer, user, technician or the like, operational status, for example.

[0091] The offset configuration of the light pipes 102 enable the input ends 105 thereof to be positioned within the patch panel assemblies 30 at a location below the level of the output ends 106. The housings 46 include individual channels 80 that are disposed in the body portions 50 thereof, and as illustrated in FIG. 13, the channels 80 may include a rear half 81 in the form of a tail slot, which is shown as a rectangular or square portion, that communicates with the second openings 56 of the housing 46. The channels 80 further include a front half 82, which also may take the form of square or rectangular channels in which the S-bend portions of the light pipes 102 extend. Although not shown, the housing body portions 50 may include depressions formed in the bottom surfaces 50a of the body portions 50 that engage portions of the outer surfaces of the light pipes 102.

[0092] The rear portions of the light pipes 102 that form the input ends 105 of the light pipes are square or rectangular in configuration which matches that of the channels rear halves 81, while the light pipe front portions that define the light pipe output ends 106 are generally cylindrical in configuration, particularly to fit into the face plate indicator openings 44. The LEDs 100 and their supports 101 depend downwardly from the bottom surfaces 98 of the circuit boards 86 and are preferably configured to fit in at least a portion of the rear channel halves 81. In this manner, the LEDs 100 may be placed into confronting and preferably abutting contact with the light pipe input ends 105. The light pipes 102 may illuminate and thereupon indicate the status of individual ports 31a, such as by color, or operation of the ports 31a in transmitting data.

[0093] It can be seen that the housings 46 serve to divide the patch panel assembly 30 and its associated face plate openings 42 into discrete groups of ports 31a, where each such port includes a jack opening of a housing, a data jack 110 inserted therein and a cable terminated to the jack. The number of ports 31a defined by each housing 46 can be chosen by the designer. As noted above, the number of ports 31a associated with each of the housings 46 in a patch panel assembly of the Present Disclosure will be chosen from the group of 1, 2, 3, 4, 6, 8, 12 or 24. This variety gives the end user the ability to utilize high-speed and low-speed ports in the same patch panel. It further increases the efficiency of repair, replacement or upgrading of the electronics associated with particular ports, or groups of ports 31a. Still further it permits an end user the ability to easily build his network, by equipping patch panels with only the housings to define all of the ports, but purchasing and installing an initial number of jacks and associated circuit board or boards with which to start. Then the end user may add additional circuit boards and jacks to second, third and subsequent housing. This saves on initial start-up costs.

[0094] Likewise, patch panels of the Present Disclosure may be upgraded in such a step-wise fashion. The patch panels of the '707 Patent described above, required time consuming removal of the two circuit boards for upgrading, repair and replacement, resulting in serious downtime of the patch panel. Patch panel assemblies of the Present Disclosure eliminate this disadvantage. The jacks 110 of the Present Disclosure are also uniquely insertable and removable so that if repair, replacement or upgrading of the jacks must occur, it can be done to the jacks individually, without necessitating the removal of the circuit boards of any of the components associated therewith.

[0095] Turning now to FIGS. 13 and 17-22, a data jack 110 constructed in accordance with the principles of the Present Disclosure is seen to have front and rear interengaging covers 124, 126, respectively, which cooperatively define a jack housing that accommodates the internal structure of the jack 110 and which includes a rear opening 127 that accommodate the termination end of a multi-wire cable (not shown) in the jack housing. The jack front cover 124 includes a pair of catches, or stops 130 that are engaged by elongated hook portions 129 that are formed as part of the jack rear cover 126. As noted above, the jack 110 includes one or more catches 125 that are disposed on a top surface of the jack 110, and in the drawings, the catches 125 are illustrated in position on the jack front cover 124. A cable clamp 128, which may be spring-biased is mounted within the rear jack cover 126 proximate to the rear opening 127 to hold the cable in place with respect to the jack 110.

[0096] The internal components of the jack are illustrated in FIGS. 19-20 and include an inner frame member 112 that supports a circuit board 113 on one side and a cable wire termination block 114 on the other side of the frame member 112. IDT terminals 115 are supported within the termination block 114 and the IDT terminals 115 includes tail portions 15a that contact the inner circuit board 113 by way of a series of vias 113a. The IDT terminal contact portions extend longitudinally in the terminal block 114 on opposite sides of wire slots formed therein. The other side of the inner circuit board 113 supports an array of terminals 116 that are partially held in place by a two-piece clam-shell support, shown as a terminal comb 117.

[0097] The jack front cover 124 has a central opening that defines a receptacle 118 that is configured to receive a patch panel cable plug therein (not shown) and the jack terminals 116 extend longitudinally within the jack receptacle 118 and the free ends 116a thereof are captured within grooves or other openings formed in a positioning support plate 116b. The jack terminals 116 are captured, but are free to deflect upwardly and downwardly in a vertical direction under pressure created by the insertion of the cable plug into the receptacle 118. The jack 110 further may include an internal switch assembly 120, illustrated as a horizontal plate 120a which supports two terminals 121, 122. The first one 121 of the terminals has a U-shaped configuration that preferably extends in a single plane. The second terminal 122 also has a U-shape but is bent slightly back upon itself so that is extends in two intersecting planes. Both terminals 121, 122 are terminated at their tails to the jack circuit board 113 and both extend longitudinally in the jack receptacle 118. The second terminal 122 is arranged so that it extends within a space bounded by the first terminal 121 and it is slightly angled upwardly with respect to the first terminal 121 so that it is spaced vertically apart from it.

[0098] The front end 122a of the second terminal 122 is bent backwards at an upward angle as illustrated to present a tang that a cable plug engages when it is inserted into the jack receptacle 118. The cable plug makes contact with the angled front end 122a of the second terminal 122 and forces it downward into shorting contact with the first terminal 121. These terminals 121, 122 comprise an internal switch in each jack that can provide a connecting signal to the patch panel electronics, which indicates complete insertion by a cable plug into the jack receptacle 118 as well as indicates a complete connection with the jack terminals 116. If the signal provided by the shorting contact merely indicates that the plug is fully inserted, it informs the installer and/or end user that the patch panel port should be live and producing an operational signal. No signal will indicate that either the cable or the cable plug is bad, while a signal will indicate the cable and its plugs are good. When the assemblies of the Present Disclosure are utilized with shielded modular plugs, the jacks 110 include opposing ground terminals 118a that will establish a ground circuit between the opposing plugs and the jack covers 124 allowing for a through ground connection.

[0099] Importantly, the jacks 110 of the patch panel assemblies 30 of the Present Disclosure are singular jacks, meaning that they are individual jacks that may be selectively inserted into and removed from the housing first openings 55. As such, they can be terminated to individual associated cables by an installer prior to installation of them into the patch panel frame 32. This is an advantage over a structure similar or identical that described in the '707 Patent, where the jack housings are attached to one surface of one circuit board and the termination blocks are attached to the other surface of the one circuit board. Such a structure will not permit the use of a punch down tool when the jack housing and termination block are mounted to a circuit board. With the structure of the jacks 110 of the Present Disclosure, the termination blocks 114 are held in place within the jack front cover 124 by way of stop surfaces 114a that abuttingly engage stop surfaces disposed within the interior of the front jack cover 124. Additionally, the termination blocks 114 may include catches 114b that project outwardly and which are received in corresponding openings 125a of the jack front cover 125. The catches 114b may be depressed inwardly to free them from engagement with the jack front cover 124 so that the interior assembly may be removed.

[0100] The termination blocks 114 are therefore held reliably in place within the jack front covers and they extend rearwardly therefrom. An ordinary IDT wire termination tool may be used and because the jack front covers 125 are preferably made from metal, they can define hard reaction surfaces to bear against a termination jig, or tool, during the termination process. There is no worry about damaging the circuit boards 86 as there would be in a structure in accordance with the '707 Patent. In yet another important aspect of the Present Disclosure, the jacks 110 are provided with exterior terminals, or contacts 138, which are configured to contact the housing terminal first tails 65 when the jacks are inserted into the housings 46. These exterior terminals 138 are terminated at their tail portions 139 to the inner circuit board 113 and are connected to the jack terminals 115, 116 by traces disposed on the circuit board 113. The terminals 138 have contact portions 140 at their free ends and the terminal 138 are shown as having an overall C-shape in order to define a curved front portion 140a of the terminal contact portions 140. The jack connecting terminals curved front portions 140a will contact the housing terminal first tails 65 and they and the free end contact portions 140 will preferably contact the first terminal contact portions 65a.

[0101] This manner of insertion of a jack 110 into a first opening 55 of a patch panel housing 46 effectively provides a connecting path, via the housing interposed terminals 63, between the jack inner terminals 116 and circuits and electronic elements on a circuit board 86. The cables terminated to the jacks 110 are supported by the cable manager 40 and they may be supported by weaving them in and out of the cable manager slots 41 thereof. The cable manager 40, in its offset configuration maintains the cables at a height above the frame base plate 34 no less than NH in order to provide clearance to the panel frame nest 108 to accommodate the circuit board modules 36 in their movement in and out of engagement with the housing circuit board openings 56.

[0102] With the ports of the patch panel assemblies of the Present Disclosure separated into discrete groups, single groups of ports or all of the ports of the patch panel may now be replaced, repaired and/or upgraded without having to take all of the patch panel ports out of operation. The jacks of any single housing may be replaced individually without disturbing the other jacks in that housing or the remaining jacks in the patch panel assembly. Likewise, the circuit board may be removed and replaced, repaired or upgraded individually by pulling it out or inserting it underneath the cable array and associated jacks, without requiring removal of any of the jacks or housings. A single circuit board may be easily replaced with multiple circuit boards, either standing alone or as incorporated into a module type structure as discussed above. The modular ability of the patch panel assemblies can even permit an end user to utilize some of the ports of a patch panel for high-speed applications, while maintaining the remaining ports of the patch panel for low-speed applications, an aspect that was not feasibly accomplished in patch panels of the '707 Patent style.

[0103] While a preferred embodiment of the Present Disclosure is shown and described, it is envisioned that those skilled in the art may devise various modifications without departing from the spirit and scope of the foregoing Description and the appended Claims.
