DETAILED DESCRIPTION

(24) This description provides examples, and is not intended to unnecessarily limit the scope, applicability or configuration of the invention. Rather, the ensuing description will provide those skilled in the art with an enabling description for implementing embodiments of the invention. Various changes may be made in the function and arrangement of elements.

(25) Thus, various embodiments may omit, substitute, and/or add various procedures or components as appropriate. For instance, aspects and elements described with respect to certain embodiments may be combined in various other embodiments. It should also be appreciated that the following systems, devices, and components may individually or collectively be components of a larger system, wherein other procedures may take precedence over or otherwise modify their application.

(26) FIG. 1 is an illustration of a representative PDU 100 of an embodiment that includes various features of the present disclosure. The PDU 100 includes a PDU housing 102 and a power input 104 that penetrates the housing 102 and may be connected to an external power source. The PDU 100 according to this embodiment includes housing 102 that is vertically mountable in an equipment rack, although it will be understood that other form factors may be used, such as a horizontally mountable housing. A plurality of outlet modules 106 may be located within the housing 102 and are accessible through apertures 108 in a front face 110 of the housing 102. The outlet modules 106 will be described in more detail below. The PDU 100 of FIG. 1 can include a number of circuit breakers 112 that provide over-current protection for one or more associated outlet modules 106. The PDU 100 can also include a communications module 114 that may be coupleable with one or more of a local computer, local computer network, and/or remote computer network. A display portion 116 may be used to provide a local display of information related to current operating parameters of the PDU 100, such as the quantity of current being provided through the input and/or one or more of the outlets, or the power or energy consumed by one or more outlets of the PDU, to name a few. Although the embodiment of FIG. 1 depicts outlet modules having 14 outlets, other embodiments can include outlet modules with more or fewer outlets.

(27) FIGS. 2 and 3A illustrate a combination outlet module 106 having two combination outlet cores 120 mounted on the surface of a mounting board, such as a printed circuit board 122. As explained more fully below, the outlet cores 120 incorporate slots and electrical contacts for a first connector type (e.g., standard C13/C14) as well as a second connector type (e.g., standard C19/C20). In other words, the outlet core has the envelope of a C13 outlet, but can accept both C14 and C20 plugs. The standard connector types referred to herein (e.g., C13, C14, C19, and C20) all refer to industry standard connectors defined in International Electro technical Commission (IEC) standard publication IEC60320 as of the filing date of the present application.

(28) With further reference to FIGS. 3B and 3C, in some embodiments, the outlet module 106 can include a removable outlet shroud 124. The outlet shroud 124 can be positioned around a corresponding combination outlet core 120 in order to prevent a C20 plug 10 from being connected to the outlet core 120 and to provide for proper mating of the C14 plug 12 to the outlet core 120. The term shroud as used herein refers to a sleeve like structure that is spaced apart from the outlet core 120, leaving a gap between the core 120 and the shroud 124 to receive the first connector type. In some embodiments, the outlet module 106 can include a removable adapter sleeve 126 positioned around the outlet core 120 in order to prevent a C14 plug 12 from being connected to the outlet core 120 and to provide a core shape corresponding to a C20 plug 10 in order to provide for proper mating of the C20 plug 10 to the outlet core 120.

(29) Although the embodiments are shown and described with respect to C13/C14 and C19/C20 connectors, other connector combinations could be used. Other suitable connector types might include, for example and without limitation, industry standard connectors, such as IEC C2, C4, C6, C8, C10, C12, C16, C16A, C18, C22, C24 or NEMA 5-10R, 5-15R, 5-20R, 6-20R, 6-30R, 6-50R, L15-20R, L15-30R, L21-20R, L21-30R. In various embodiments, the connectors could include connectors defined in the IEC standard as of the filing date of the present application.

(30) As shown in FIGS. 4 and 5, the combination outlet core 120 has an input side 130 and an output side 132 with three apertures 134/136 extending therebetween. The outlet core 120 has a core outer surface 142 configured to mate with a first connector type. For example, in the depicted embodiment the core outer surface 142 is configured as a C13 outlet to mate with a C14 plug. The apertures 134/136 are each configured to receive mating terminals corresponding to both the first connector type (e.g., C14) and the second connector type (e.g., C20). In this embodiment, the apertures 134/136 comprise intersecting cross-wise slots or T-shaped apertures as shown in FIG. 4, for example. Accordingly, the apertures 134/136 can accept the terminals of a C20 plug and the perpendicularly oriented terminals of a C14 plug. In some embodiments, the combination outlet core 120 can comprise injection molded plastic, for example. In some embodiments, the combination outlet core 120 can include one or more cavities 131 for reducing the amount of material needed to mold the core.

(31) Apertures 136 are aligned with respect to each other and aperture 134 is oriented opposite to and between the apertures 136, as shown. With specific reference to FIG. 5, the input side 130 of the combination outlet core 120 can include a pair of bosses 140 and corresponding mounting holes 138. The bosses 140 can be used to locate the combination outlet core 120 on the printed circuit board 122 (FIG. 3A). Suitable fasteners (not shown) can be threaded into the mounting holes 138 in order to attach the outlet core 120 to the printed circuit board 122 (FIG. 3A). Other mounting arrangements are possible. For example, the outlet core 120 can be adhered to the printed circuit board 122 with a suitable adhesive. In still other embodiments, the outlet core 120 can be captured on the circuit board 122 by electrical terminals which can be soldered to the circuit board.

(32) With reference to FIGS. 6A and 6B, a plurality of electrical terminals 150 are each positioned in a corresponding one of the apertures 134/136. Each aperture 134/136 includes corresponding flanges 144 and 146 to define the aperture opening. Each aperture 134/136 also includes a pair of notches 133 to properly position the terminals 150 in their respective apertures. With further reference to FIG. 7, each electrical terminal 150 can include a connection tab 156, a pair of opposed prongs 152, and a transverse prong 154. Each of the opposed prongs 152 includes a locating pin 153 configured to mate with the notches 133 (FIG. 6A). The opposed prongs 152 are configured to connect with a mating terminal of a first connector type (e.g., C14) by receiving the mating terminal therebetween. The mating terminal of a second connector type (e.g., C20) can be received between the pair of opposed prongs 152 on one side and the transverse prong 154 on the opposite side. In some embodiments, the terminals 150 can be integrally formed from a single piece of conductive material. In some embodiments, electrical terminals 150 can be constructed from suitable electrically conductive materials such as tin, gold, silver, copper, phosphor bronze, and the like. Multiple materials can be used in combination. In one embodiment, the terminals can comprise copper alloy with a tin plating.

(33) In some embodiments, the terminals can comprise multiple pieces or parts. For example, the electrical terminals 174, shown in FIGS. 8A and 8B, each comprise first and second terminal parts 176 and 178, respectively. The first terminal part 176 can include a connection tab 180 and a pair of opposed prongs 182. The opposed prongs 182 are configured to connect with a mating terminal of a first connector type (e.g., C14) by receiving the mating terminal therebetween.

(34) The second terminal part 178 also includes a connection tab 184 and a pair of opposed prongs 186. The mating terminal of a second connector type (e.g., C20) can be received between the pair of opposed prongs 186. In some embodiments, a notch 188 is formed in one of the pair of opposed prongs 186. The notch 188 provides clearance for the mating terminal of the first connector type. The first and second terminal parts, 176 and 178, are maintained in position relative to each other in an orthogonal orientation by virtue of being connected (e.g., soldered) to a circuit board 190 (FIG. 8A). In some embodiments, each of the first and second terminal parts 176 and 178 can be integrally formed from a single piece of conductive material.

(35) As shown in FIG. 9A, the removable shroud 124 is configured to be positioned around a corresponding outlet core 120 (FIG. 6B) and includes a shroud inner surface 160 configured to receive the first connector type (e.g., C14). The removable shroud 124 also includes a shroud outer surface 162 that can be at least partially congruent with the apertures 108 in the front face 110 of the PDU housing (FIG. 2). In some embodiments, the shroud 124 includes a shroud flange 164 having a shroud aperture 166 at least partially congruent with the core outer surface 142 (FIG. 4), which centers the shroud 124 around the combination outlet core 120. In some embodiments, the shroud aperture 166 is sized to provide a friction fit against the core outer surface 120, thereby retaining the shroud 124 on the core 120.

(36) FIGS. 9B and 9C illustrate a removable shroud 234 including a mounting flange 261 and locking tabs 263. The removable shroud 234 is configured to be positioned around a corresponding outlet core 120 (FIG. 6B) and includes a shroud inner surface 260 configured to receive the first connector type (e.g., C14). The removable shroud 234 also includes a shroud outer surface 262 that can be at least partially congruent with the apertures 108 in the front face 110 of the PDU housing (FIG. 2). The mounting flange 261 rests against the front face 110 and grooves 267, formed in the locking tabs 263, engage the PDU housing 102, thereby releasably locking the shroud 234 to the housing 102 (FIG. 1). The locking tabs 263 can include lead-in surfaces 269 to facilitate installing the shroud 234 into the housing 102. The locking tabs 263 can also include gripping features, such as grooves 271, to facilitate squeezing the tabs together for removal of the shroud 234. In some embodiments, the locking tabs 263 can include latch grooves 265 to engage with a mated first connector type. In some embodiments, the shroud 234 includes a shroud flange 264 having a shroud aperture 266 at least partially congruent with the core outer surface 142 (FIG. 4). In some embodiments, the shroud aperture 266 includes bumps 267 to center the shroud aperture 266 on the outlet core 120 (FIG. 6B).

(37) As shown in FIG. 10A, the adapter sleeve 126 is configured to be positioned around a corresponding outlet core 120 (FIG. 6B) and includes a sleeve outer surface 172 configured to mate with the second connector type (e.g., C20). In some embodiments, the adapter sleeve 126 includes a sleeve aperture 170 at least partially congruent with the core outer surface 142 (FIG. 4). In some embodiments, the sleeve aperture 170 is sized to provide a friction fit against the core outer surface 120, thereby retaining the sleeve 126 on the core 120. In other embodiments, the shroud 124 and the sleeve 126 can be retained on the core 120 with magnets, snaps, latches, and/or tabs, to name a few. By using the disclosed combination outlets 120 along with various combinations of the outlet shrouds 124 and the adapter sleeves 126, a PDU can be adapted for different initial applications as well as changing requirements resulting from equipment changes.

(38) As shown in FIG. 10B, the adapter sleeve 236 is configured to be positioned around a corresponding outlet core 120 (FIG. 6B) and includes a sleeve outer surface 272 configured to mate with the second connector type (e.g., C20). In some embodiments, the adapter sleeve 236 includes a sleeve aperture 270 at least partially congruent with the core outer surface 142 (FIG. 4). In some embodiments, the aperture 270 includes ribs 275 positioned around the opening to center the sleeve 236 on the core 120. In some embodiments, the sleeve aperture 270 is sized such that the ribs 275 provide a friction fit against the core outer surface 120, thereby retaining the sleeve 236 on the core 120. The sleeve 236 can include a slot 276 that can be expanded with a tool (e.g., a screwdriver) to facilitate installation and removal of the sleeve 236. In some embodiments, the slot 276 can include lead-in chamfers 278 to guide the tool to the slot 276.

(39) FIGS. 11A and 11B illustrate an outlet shroud assembly 200 that locks onto a C14 plug according to a representative embodiment. The locking outlet shroud assembly 200 includes a shroud 202 and a lock frame 204. The shroud 202 is configured to be positioned around a corresponding outlet core 120 (e.g., FIG. 6B) and includes corner flanges 212 which define a shroud inner surface 214 configured to receive the first connector type (e.g., C14). The shroud 202 includes a shroud outer surface 203 that can be at least partially congruent with the aperture 108 in the front face 110 of the PDU housing (FIG. 2). In some embodiments, retainer tabs 210 are formed in the surface 203 of the shroud 202 to engage an underside of the front face 110, thereby retaining the shroud assembly 200 in the aperture 108.

The combination outlet connector bank 400 includes a recessed surface 405 which is part of the unitary body 402 from which the outlet cores (420, 422, 424) extend toward the surrounding flange 406. In some embodiments, the unitary body 402 can comprise injection molded plastic, for example. As with the combination outlet connectors described above, the combination outlet core 420 incorporates T-shaped apertures and corresponding electrical contacts 150 to connect with a first connector type (e.g., standard C13/C14) as well as a second connector type (e.g., standard C19/C20). In some embodiments, the combination outlet connector bank 400 can include one or more outlet shrouds 124. The outlet shroud 124 can be positioned around the corresponding combination outlet core 420 in order to prevent a C20 plug from being connected to the outlet core 420. The shroud's outer surface can be at least partially congruent with an inner surface 408 of the unitary body 402, as shown. In some embodiments, the combination outlet connector bank 400 can include one or more adapter sleeves 126 (FIG. 3A) positionable around a corresponding outlet core 420 in order to prevent a C14 plug from being connected to the outlet core 420 and to provide a core shape corresponding to a C20 plug to properly align and capture the plug on the core.

(43) In some embodiments, the outlet shrouds and adapter sleeves can include one or more magnets, the presence or absence of which can be used to determine whether a shroud or a sleeve is present on a particular combination outlet core. For example, the outlet shroud can include a single magnet and the adapter sleeve can include two magnets to indicate, to a suitable processing system, that an outlet shroud or an adapter sleeve is present, respectively. In some embodiments, the magnets can be cylindrical magnets comprising a suitable magnetic material such as neodymium, for example. The outlet module's printed circuit board can include one or more hall effect sensors to detect which if any magnets are present, by sensing the magnetic field generated by the installed magnets. Thus, the presence or absence of a shroud or sleeve can be determined based on which hall effect sensors detect a magnet affixed to the shroud or sleeve. A similar identification system is further described in co-pending U.S. patent application Ser. No. 15/497,063, filed Apr. 25, 2017, the disclosure of which is hereby incorporated by reference in its entirety. Other sensors can be used such as electrical contacts, optical sensors, and electro-mechanical switches, to name a few.
