CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Application No. 63/129,035 filed December 22, 2020 and U.S. Non-Provisional Application No. 17/557,498 filed December 21, 2021, which are incorporated by reference herein in their entirety.

TECHNICAL FIELD

[0002] The present disclosure generally relates to the field of power distribution units, and more particularly to a power distribution box for a rack power distribution unit.

BACKGROUND

[0003] Conventional systems employ remote power panels (RPPs), also referred to as floor power distribution units (PDUs), to distribute power to rack power distribution units (rPDUs) within a data center. The RPPs are used to divide the power from an input power source into different circuits using a breaker panel and may be coupled to the rPDUs using PDU whips. The PDU whips may be used to electrically couple the RPP to the rPDUs within the data center. One end of the whip (e.g., the tail of the whip) is hardwired on-site by an electrician into a breaker on the RPP. The other end of the whip contains an outlet to couple to the rPDU. The rPDUs are used to distribute power within a computer cabinet to individual pieces of information technology (IT) equipment.

[0004] The hardwiring of the tail of the PDU whip, using an electrician, increases the installation time, the cost of installation, and the cost of materials. Further, working on the data center floor requires the electrician to obtain site access, which is often difficult to obtain. As such, it would be advantageous to provide a system or apparatus to remedy the shortcomings of the conventional approaches identified above. SUMMARY

[0005] Accordingly, the present disclosure is directed to a power distribution box (PDB). The power distribution box may include a housing, one or more outlets, one or more outlet plugs, one or more circuit breakers, and at least one PDU whip.

DETAILED DESCRIPTION

[0020] Reference will now be made in detail to the subject matter disclosed, which is illustrated in the accompanying drawings. [0021] Conventional systems employ remote power panels (RPPs), also referred to as floor power distribution units (PDUs), to distribute power to rack power distribution units (rPDUs) within a data center. The RPPs are used to divide the power from an input power source into different circuits using a breaker panel and may be coupled to the rPDUs using PDU whips. The PDU whips may be used to electrically couple the RPP to the rPDUs within the data center. One end of the whip (e.g., the tail of the whip) is hardwired on-site by an electrician into a breaker on the RPP. The other end of the whip contains an outlet to couple to the rPDU. The rPDUs are used to distribute power within a computer cabinet to individual pieces of information technology (IT) equipment.

[0022] The hardwiring of the tail of the PDU whip, using an electrician, increases the installation time, the cost of installation, and the cost of materials. Further, working on the data center floor requires the electrician to obtain site access, which is often difficult to obtain. As such, it would be advantageous to provide a system or apparatus to remedy the shortcomings of the conventional approaches identified above.

[0023] Accordingly, the present disclosure is directed to a power distribution box. More particularly, the present disclosure is directed to a power distribution box that simplifies installation and scalability of power distribution units (PDUs) to rack PDUs (rPDUs) by replacing conventional power panels. Specifically, the present disclosure is directed to a power distribution box including at least one PDU whip configured to couple to a portion of the rPDU. In this regard, the power distribution box is able to distribute power to multiple rPDUs using the PDU whip without the need for an electrician, thereby simplifying on-site installation and reducing costs.

[0024] FIGS. 1A-7 generally illustrate a power distribution box, in accordance with one or more embodiments of the present disclosure.

[0025] FIGS. 1A-1C illustrate a power distribution box 100, in accordance with one or more embodiments of the present disclosure.

[0026] The power distribution box 100 may include a housing 102 (or outer chassis 102) including one or more panels 104. For example, the housing 102 may include at least a front panel 104, a back panel 104, one or more side panels 104, a top panel 104, and a rear panel 104. The one or more panels 104 may define a cavity 106 configured to house one or more components of the power distribution box 100, as discussed further herein.

[0027] Referring to FIG. 1A, the power distribution box 100 may include one or more circuit breakers 108 (e.g., a single-pole breaker 110, three-pole breakers 112, or the like). For example, the power distribution box 100 may include one or more circuit breakers 108 coupled to the front panel 104 of the housing 102.

[0028] The one or more circuit breakers 108 may be configured to couple to an infrastructure device (e.g., cooling or monitoring system). For example, as shown in FIG. 1A, the power distribution box 100 may include a single-pole circuit breaker 110 for an infrastructure device. For instance, the single-pole circuit breaker 110 may be a 20 amp (U.S.) or 16 amp (EMEA) circuit breaker.

[0029] The one or more circuit breakers 108 may be further configured to couple to one or more rack PDUs (rPDUs). The one or more rPDUs may include one or more universal PDUs (UPDUs). A UPDU may refer to a rack power distribution unit that includes a universal input and detachable facility side cable that allows a single model to be installed globally. In one example, the rPDU may be a VERTIV™ GEIST™ Switched Rack Power Distribution Unit, a product of the assignee of the present application. In another example, a UPDU may be a VERTIV™ GEIST™ Universal Power Distribution Unit, a product of the assignee of the present application. Referring once again to FIG. 1A, the power distribution box 100 may include four three-pole circuit breakers 112 for four UPDUs (e.g., two racks). For instance, the three-pole circuit breakers may be 32 amp circuit breakers.

[0030] The one or more circuit breakers 108 may include one or more user input devices 114 (e.g., toggles, levers, buttons, or the like) for switching behavior. The one or more circuit breakers 108 may further include one or more visual status indicators 116 to easily identify the circuit status. For example, the one or more circuit breakers 108 may include one or more LED status indicators 116.

[0031] It is noted that placement of the circuit breakers 108 (e.g., single-pole breaker 110, three-pole breakers 112, or the like) in the front area of the power distribution box 100 (e.g., on the front panel 104) may allow easy monitoring by a data center employee when the power distribution box 100 is mounted within a rack (as discussed further herein with respect to FIGS. 4A-4C).

[0032] Referring to FIG. 1B, the power distribution box 100 may include one or more outlets 118 positioned on the one or more panels 104 of the housing 102. For example, the one or more outlets 118 may be positioned on the back panel 104 of the housing 102. For instance, the power distribution box 100 may include one or more C19 outlets in compliance with IEC60320 standards and configured to receive one or more C20 plugs. Although FIG. 1B depicts the power distribution box 100 including two C19 outlets, it is noted herein that the power distribution box 100 may include any number of outlets and any type of outlet known in the art.

[0033] The power distribution box 100 may further include one or more output plugs 120 coupled to one or more portions of the one or more panels 104 of the housing 102. For example, the one or more output plugs 120 may be coupled to one or more portions of the back panel 104 of the housing 102. For instance, the power distribution box 100 may include four output plugs 120 coupled to the back panel 104 of the housing.

[0034] The one or more output plugs 120 may be configured to couple to one or more power distribution unit (PDU) whips 122. For example, the one or more output plugs 120 may be coupled to the PDU whips 122 via one or more fastening methods such as, but not limited to, bolts, adhesives (e.g., glue or tape), or the like. Byway of another example, the one or more output plugs 120 may include a connecting member configured to couple to the PDU whip 122. In this example, each PDU whip 122 may include a connecting member on a proximal end of the PDU whip (similar to the connecting member 123 on the distal end, as shown in FIG. 1C) and a connecting member 123 on a distal end of the PDU whip 122, where the proximal end connecting member may be configured to couple to a corresponding connecting member of the one or more output plugs 120 and the distal end connecting member 123 may be configured to couple to the rPDU (e.g., UPDU).

[0035] The power distribution box 100 may include at least one PDU whip 122 coupled to an output plug of the one or more output plugs 120 For example as shown in FIGS 1A-1C, the power distribution box 100 may include four PDU whips 122 (e.g., prewired PDU whips) coupled to the four output plugs 120. Each PDU whip 122 may be configured to distribute power to one UPDU. In this regard, the four PDU whips 122 may distribute power to four UPDUs (e.g., two racks).

[0036] Referring to FIGS. 1B-1D, the power distribution box 100 may include a removable access panel 124 configured to reversibly couple to one or more portions of the one more panels 104. For example, the removable access panel 124 may be configured to reversibly couple to one or more portions of the top panel 104 of the housing 102. The removable access panel 124, when removed (e.g., not coupled to the one or more panels 104 of the housing 102 or outer chassis), may be configured provide access to one or more components within the power distribution box 100. For example, when removed, the top panel 104 may include an opening 126 to allow access to the one or more components of the power distribution box 100 housed within the cavity 106. The removable access panel, when attached (e.g., coupled to the one or more panels 104 of the outer chassis 102), may be configured to protect the one or more components within the power distribution box 100 from the external environment. The removable access panel may be reversibly couplable to the power distribution box 100 using any fastening method known in the art including, but not limited to, one or more fasteners, one or more hinge assemblies, and the like.

[0037] Referring to FIG. 1C, the one or more circuit breakers 108 may be coupled to one or more components of the power distribution box 100 using one or more wires/cables. For example, each of the one or more three-pole circuit breakers 112 for the UPDU may couple to each UPDU (through the PDU whip 122) using a set of wires/cables 128. In this instance, each three-pole circuit breaker 112 may couple to the UPDU via a set of wires/cables 128 including at least a first wire coupled to the first pole of the three-pole breaker 112, a second wire coupled to the second pole of the three-pole breaker 112, and a third wire coupled to the third pole of the three-pole breaker 112. By way of another example, the single-pole circuit breaker 110 for the infrastructure device may couple to the infrastructure device using a single wire 130. In this instance, the infrastructure device is configured to couple to the power distribution box 100 using one of the one or more outlets 118. [0038] Each PDU whip 122 may couple to the one or more output plugs 120 of the power distribution box 100, such that each PDU whip 122 may connect to a corresponding circuit breaker 112 for the UPDU via the set of wires 128 of the breaker 112 (e.g., the at least first wire, second wire, and third wire). In some embodiments, each PDU whip 122 may be hardwired to a corresponding circuit breaker 112 for the UPDU via the set of wires 128 of the breaker 112. In some embodiments, the one or more output plugs 120 of the power distribution box 100 includes a connecting member configured to couple the PDU whip 122 to the one or more output plugs 120. For example, the PDU whip 122 may include a connecting member on a proximal end of the PDU whip (similar to the connecting member 123 on the distal end, as shown in FIG. 1C) configured to couple to a corresponding connecting member of the one or more output plugs 120. In this example, the corresponding connecting member of the one or more output plugs 120 may be hardwired to a corresponding circuit breaker 112 for the UPDU via the set of wires 128 of the breaker 112, such that the corresponding connecting member of the one or more output plugs 120 may electrically couple each PDU whip 122 to a corresponding circuit breaker 112 for the UPDU. It is noted that where the power distribution box 100 includes a plurality of PDU whips 122, each PDU whip 122 may be connected to a respective breaker.

[0039] The power distribution box 100 may further include one or more grounding wires 132. The one or more grounding wires 132 may be configured to ground the separate pieces of metal together. For example, the power distribution box 100 may include one or more grounding wires 132 coupled to one or more portions of the cavity 106 to ground the separate pieces of the metal cavity together. By way of another example, the power distribution box 100 may include one or more grounding wires 132 coupled to the PDU whips 122 and a metal portion of the cavity 106.

[0040] Referring to FIGS. 1C-1D, the power distribution box 100 may include one or more distribution blocks 134. Referring to FIG. 1C, the one or more distribution blocks 134 may couple to one or more components of the power distribution box 100. For example, the one or more distribution blocks 134 may couple to the one or more circuit breakers 108. In one instance, the one or more distribution blocks 134 may couple to the one or more circuit breakers 112 for the UPDU using one or more sets of wires 136. In this regard, a first distribution block 134 may couple to a first pole of the one or more circuit breakers 112 via a first set of wires, a second distribution block 134 may couple to a second pole of the one or more circuit breakers 112 via a second set of wires, and a third distribution block may couple to a third pole of the one or more circuit breakers 112 via a third set of wires.

[0041] In another instance, the one or more distribution blocks 134 may couple to the one or more circuit breakers 110 for the infrastructure device using a wire 138 of the set of wires 138. In this regard, a distribution block 134 of the one or more distribution blocks 134 may couple to the single pole of the circuit breaker 110 via a single wire 138.

[0042] By way of another example, the one or more distribution blocks 134 may couple to one or more PDU whips 122. For instance, as shown in FIG. 1C, a distribution block 134 may couple to a PDU whip 122 via the set of wires 140. The set of wires 140 may be neutral wires (e.g., wire not required to connect to a circuit breaker) configured to directly couple the distribution block 134 to the PDU whip 122.

[0043] FIGS. 2A-2C illustrate a plurality of a power distribution boxes 100 in a daisychain configuration 200, in accordance with one or more embodiments of the present disclosure. It is noted that the embodiments and enabling technologies described previously herein in the context of the power distribution box 100 and/or the components of the power distribution box 100 should be interpreted to extend to the daisy-chain configuration 200.

[0044] The power distribution box 100 may be configured to couple to one or more adjacent power distribution boxes to form a daisy-chain 200 of power distribution boxes 100. For example, as shown in FIGS. 2A-2C, the daisy-chain 200 of power distribution boxes may include at least a first power distribution box, a second power distribution box, a third power distribution box, and a fourth power distribution box. Although FIGS. 2A-2C depict a specific number and configuration of power distribution boxes 100, it is noted that the daisy-chain 200 may include any number and configuration of power distribution boxes 100.

[0045] The one or more distribution blocks 134 of the power distribution box 100 may be configured to distribute electrical power from a single input source (e.g., a main power input) to several devices in the branched circuit (e.g., the daisy-chained PDBs 200). For example, the one or more distribution blocks 134 may couple to one or more daisy chain wires 202. Referring to FIG. 2B, the daisy chain wires 202 may be configured to electrically couple a plurality of power distribution boxes 100 together in sequence using the one or more distribution blocks 134 after receiving power from the main input power conductors 206.

[0046] Each power distribution box 100 may include one or more openings 204 for the main power input conductors 206 and daisy chain wires 202 to pass through, such that the power distribution boxes 100 are configured for daisy chain capability (e.g., connecting a plurality of power distribution boxes together in a daisy-chain configuration 200). Referring to FIG. 2B, the one or more openings 204 may be configured to receive the one or more daisy chain wires 202 coupled to the one or more distribution blocks 134. Further, the one or more openings 204 may be configured to receive the main power input conductor 206.

[0047] The power distribution box 100 configured in the daisy-chain configuration 200 may include one or more input power sources. For example, the power distribution box 100 may include a single input power source coupled to the power distribution box via a first input conductor 206. By way of another example, the power distribution box 100 may include two input power sources coupled to the power distribution box 100 via two input conductors 206.

[0048] Referring to FIG. 20, the power distribution box 100 may further include one or more input covers 208 configured to cover at least a portion of the one or more openings 204. The one or more input covers 208 may be removably couplable to a portion of the power distribution box 100. For example, the one or more input covers 208 may be configured to couple to one or more portions of a back panel 104 of the housing 102 of the power distribution box 100. In this regard, the one or more input covers 208 may be utilized when the one or more openings 204 are not needed (e.g., when not utilizing the daisy chain capability).

[0049] Referring to FIG. 2C, the power distribution box 100 may further include one or more daisy wire covers 210 configured to protect the one or more daisy chain wires 202 from the external environment (e g prevent the wires from being bumped or the like). The daisy wire cover 210 may be configured to removably couple to a portion of the power distribution box 100 (e.g., back panel 104 of the housing/outer chassis 102). It is noted that the holes used to fasten the input covers to the power distribution box 100 may be used to fasten the daisy wire cover to the power distribution box, and vice versa.

[0051] Each PDU whip 122 may include a connecting member 123 (on the distal end of the whip 122) configured to couple to a URDU connecting cable 300 (e.g., a facility side cable (FSC) as shown in FIG. 3A). The UPDU connecting cable 300 (e.g., the FSC 300) may be configured to couple to a portion of the UPDU 302. For example, as shown in FIG. 3B, each UPDU 302 may include a universal input 304 configured to receive a portion of the FSC 300. In this regard, a first end 306 of the FSC 300 may couple to the UPDU 302 via the input 304 and the second portion 308 may couple to the PDU whip 122 via a connecting member 123 of the PDU whip 122.

[0052] In some embodiments, each PDU whip 122 may couple to an external connecting member configured to couple to the UPDU. For example, one end of the PDU whip may be configured to couple to a connecting member and the other end of the PDU whip may be coupled to one or more components of the power distribution box 100.

[0053] In some embodiments, each PDU whip 122 may include a connecting member configured to directly couple to the UPDU. For example, the connecting member of the PDU whip may be configured to couple to a complementary plug on the UPDU.

[0054] Although embodiments of the present disclosure are directed to coupling the power distribution box 100 to one or more U PDUs, it is noted that the power distribution box 100 may be configured to couple to any suitable rack power distribution unit (rPDU) using any corresponding connecting member and/or adaptor.

[0055] Referring to FIGS. 1A-2C, one or more components of the power distribution box 100 may be color coded. For example, the one or more circuit breakers 112 coupled to the UPDUs may be color coded to easily match which circuit is coupled to which UPDU via the PDU whip 122. In one instance, a first three-pole circuit breaker may be color coded white and a portion of the corresponding PDU whip 122 may be color coded white. In another instance, a second three-pole circuit breaker may be color coded grey and a portion of the corresponding PDU whip 122 may be color coded grey. In another instance, a third three-pole circuit breaker may be color coded dark grey and a portion of the corresponding PDU whip 122 may be color coded dark grey. In another instance, a fourth three-pole circuit breaker may be color coded black and a portion of the corresponding PDU whip 122 may be color coded black. Although FIGS. 1A-2C depict a specific color coding scheme, it is noted that the one or more components of the power distribution box 100 may be color coded using any suitable identification scheme.

[0056] By way of another example, the one or more output plugs 120 of the PDU whips 122 may be color coded to match the one or more color codes of the one or more circuit breakers 112, such that the UPDUs may be easily matched to the corresponding breaker. In one instance, a first output plug may be color coded a first color to match the first circuit breaker color that is color coded the first color. In another instance, a second output plug may be color coded a second color to match the second circuit breaker color that is color coded the second color. In another instance, a third output plug may be color coded a third color to match the third circuit breaker color that is color coded the third color. In another instance, a fourth output plug may be color coded a fourth color to match the fourth circuit breaker color that is color coded the fourth color.

In a conceptual sense, any arrangement of components to achieve the same functionality is effectively "associated" such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as "associated with" each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being "operably connected", or "operably coupled", to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being "operably couplable" to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components and/or logically interacting and/or logically interactable components.

[0065] While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein. Furthermore, it is to be understood that the invention is defined by the appended claims.
