DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS

(7) Referring now to FIG. 1A, a patch panel assembly, generally referred to using the reference numeral 10, will now be described. The patch panel assembly 10 comprises an elongate rectangular panel 12 which is configured for secure mounting to a 19 rack 14 or the like, for example through provision of a mounting bracket/flange 16, 18 at either end thereof and comprising apertures 20 through which threaded bolts (not shown) can be inserted and engaged by respective threaded bores (also not shown) in the rack 14. The panel 12 is illustratively of 1 U rack height and comprises a substantially flat front face 22 defining a plurality of rectangular openings/spaces 24 arranged along the front face side by side and which are each dimensioned to receive a respective one of a plurality of receptacle modules 26.

(8) Referring to FIG. 1B, in an alternative embodiment the panel 12 can be angled comprising two elongate sections arranged at an angle to one another and interconnected by a middle section. Each elongate section comprises two rectangular openings.

(9) Referring to FIG. 2 in addition to FIG. 1A, each receptacle module 26 comprises a rectangular bezel 28 which defines an even plurality of generally square modular jack openings 30, and such that each bezel 28 is configured for receiving a plurality of rows of modular keystone type modular jacks 32 wherein each of the openings 30 in a first of the rows is arranged adjacent and aligned with a respective opening 30 in a second of the rows. Illustratively two (2) rows of six (6) modular jacks 32 each are provided for a total of twelve (12) modular jacks 32 in each bezel 28. Additionally, a transparent cover plate/label holder 34 is provided which may receive a printed insert (not shown) for identifying each of the modular jacks 3.

(10) Still referring to FIG. 2, each modular jack 32 comprises an RJ-45 type socket 36 on a front face 38 thereof configured for receiving a first eight (8) conductor twisted pair cable terminated by a standard RJ-45 plug (not shown). Each modular jack 32 is further configured for terminating a second eight (8) conductor twisted pair cable (also not shown) on a rear face 40 thereof.

(11) Referring now to FIGS. 3A and 3B, each bezel 28 comprises a frame 42 and a front surface 44 spanning the frame 42 and which defines the openings 30. The frame is dimensioned to fit snugly in the respective rectangular space 24 while the front surface 44 is slightly larger than the rectangular space 24 such that on installation an outer edge 46 of the front surface butts against the front face 22. A first short edge 48 of the frame 42 comprises features 50 which on installation receive a respective short edge 52 of the rectangular space 24. A user actuatable latch 54 is also provided on a second short edge 56 of the frame 42 which, on installation, engages with a second short edge 58 of the rectangular space 24 for releasably securing a bezel 28 within its respective rectangular opening 24 in the frame 12. In this regard, each second short edge 58 comprises a notch 60 which is dimensioned for receiving the latch 48.

(12) Referring now to FIGS. 4A and 4B, each modular jack 32 comprises a housing 62 of generally square cross section which is dimensioned to be compatible with, for example, keystone wall plates (not shown). As known in the art, such wall plates comprise one or more keystone ports, that is a hole in the wall plate which allows the insertion of a keystone type modular receptacle or a variety of other male or female cabling connectors. Each of the modular jacks 32 comprises a pair of tabs 64 on a first side 66 thereof and a first bezel engaging feature comprising an offset tab 68 on a second side 70 thereof. In other words, the first bezel engaging feature is positioned on a first side 72 of a center 74 of a surface of the second side 70.

(13) Referring now to FIGS. 5A and 5B in addition to FIGS. 4A and 4B, each bezel 28 comprises a pair of engagement plates 76 each arranged adjacent and in parallel to a respective long edge of the bezel 28 and extending rearwards from a front surface 78 of the bezel 28. The modular jacks 32 are inserted into the bezel 28 from the rearward side 80 of the bezel 28 by tilting the modular jack 32 to first engage the pair of tabs 62 with their respective engagement plate 76. The modular jack 32 is then straightened such that the offset tab 68 engages with a respective one of a plurality of offset flexible fingers 82 also extending rearwards from a front surface 78 of the bezel 28 and the front face 38 of the modular jack 32 is flush with the front surface 78 of the bezel 26. In this regard, the flexible fingers 82 of openings 30 receiving opposed/adjacent ones of the modular jacks 32 are arranged side by side and such that they can be flexed without interfering with one another and without being impeded by an opposed one of the modular jacks 32 already positioned within its opening 30. As will now be understood by a person of ordinary skill in the art, provision of the offset tabs 68 and the offset flexible fingers 82 as well as positioning pairs of modular jacks 32 in an opposed configuration and such that the orientation of the modular jacks 32 in a first of the rows is 180 degrees to the orientation of the modular jacks 32 in a second of the rows with their respective offset tabs 68 facing one another allows the modular jacks 32 to be placed closer together, thereby increasing density. Additionally, orientation of the modular jacks 32 such that the actuating lever of a plug (both not shown) received within the receptacle modular jacks 32 is positioned outwards increases the amount of space provided to a user to disengage a plug from its respective modular jacks 32 thereby facilitating plug removal.

(14) Although the present invention has been described hereinabove by way of specific embodiments thereof, it can be modified, without departing from the spirit and nature of the subject invention as defined in the appended claims.
