Abstract

Systems, methods, and devices are provided in which cord storage cartridges are removably connected to a power distribution unit (PDU). The cord storage cartridge may include a cartridge housing having at least one aperture, a PDU interface associated with the cartridge housing and configured to removably connect the cord storage device to a mateable interface of the PDU, and a power output cord having a proximal end in electrical communication with the PDU interface and a distal end coupled with an output connector that is configured to connect to electronic equipment. The power output cord may be stowed at least partially within the cartridge housing in a retracted state and moveable through the at least one aperture to an extended state at least partially external to the cartridge housing.

First claim

We claim:

1. A power distribution unit (PDU) adapted to provision power to connected loads, comprising:
an elongate PDU housing enclosing an interior;
a power input coupled with the PDU housing and connectable to an external power source;
at least one cartridge removably connected to the PDU and supporting at least one power-related electrical component;
at least one cartridge interface associated with the PDU housing and configured to removably connect the at least one cartridge to the PDU without affecting provision of power to other components associated with the PDU, wherein the least one cartridge interface includes at least one connector extending toward the at least one cartridge; and
at least one printed circuit board (PCB) within the housing interior having the at least one cartridge interface mounted thereon.

2. The PDU of claim 1 wherein said elongate PDU housing includes one or more channels separated from and extending longitudinally along a lateral side of the interior, the at least one PCB being within the channel, said one or more channels having a combined length at least half the length of the PDU housing, said at least one cartridge removably seated within one of said channels.

3. The PDU of claim 1 , wherein the at least one cartridge interface is further configured to electrically interconnect the at least one cartridge to the power input.

4. The PDU of claim 3 , wherein the at least one cartridge interface comprises:
at least one first power connector in electrical communication with a first power line from the power input; and
at least one second power connector in electrical communication with a second power line from the power input.

5. The PDU of claim 4 , wherein the first power line is a first phase power line from the power input, and the second power line is a neutral line from the power input.

6. The PDU of claim 4 , wherein the power input is a polyphase power input, the first power line is a first phase power line from the polyphase power input, and the second power line is a second phase power line from the polyphase power input.

7. The PDU of claim 1 , wherein the at least one cartridge interface comprises:
at least one communication signal interface configured to receive at least one power-related parameter from said power-related electrical component.

8. The PDU of claim 7 , wherein the at least one communication signal interface comprises an electrical signal interface, an optical signal interface, a radio frequency signal interface, or a combination thereof.

9. The PDU of claim 7 , wherein the at least one cartridge further comprises at least one sensing device configured to sense the at least one power-related parameter.

10. The PDU of claim 7 , further comprising:
at least one communications bus in communication with the at least one communication signal interface; and
at least one communications module in communication with the at least one communications bus and configured to report the at least one power-related parameter to a network.

11. The PDU of claim 1 , wherein the at least one cartridge interface comprises:
at least one control signal interface configured to provide control signals to the at least one cartridge.

12. The PDU of claim 11 , wherein the at least one control signal interface comprises an electrical signal interface, an optical signal interface, a radio frequency signal interface, or a combination thereof.

13. The PDU of claim 11 , wherein the control signal controls operation of the at least one cartridge.

14. The PDU of claim 11 , wherein the at least one cartridge comprises at least one relay and the control signal controls the operation of the at least one relay.

15. The PDU of claim 2 , wherein the one or more channels comprises a sidewall having at least one alignment notch configured to guide the at least one cartridge into registration with the at least one cartridge interface.

16. The PDU of claim 1 , further comprising:
a plurality of cartridges disposed adjacent to each other along a substantial length of the PDU housing.

17. The PDU of claim 16 , wherein each of the plurality of cartridges comprises at least one electrical component in electrical communication with the power input and an output connector configured to connect to electronic equipment.

18. The PDU of claim 17 , wherein two or more of the plurality of cartridges comprise output connectors configured to connect to corresponding types of electronic equipment.

19. The PDU of claim 16 , wherein two or more of the plurality of cartridges are interchangeable.

20. The PDU of claim 1 , further comprising:
at least one cartridge attachment structure associated with the PDU housing; and
at least one PDU attachment mechanism associated with the at least one cartridge and configured to mateably engage with the at least one cartridge attachment structure.

21. The PDU of claim 20 , wherein the at least one cartridge attachment structure comprises a post associated with and spaced above the at least one cartridge interface mounted to the PCB, and the at least one PDU attachment mechanism comprises a notch configured to receive the post.

22. A power distribution unit (PDU), comprising:
an elongate PDU housing substantially enclosing an interior and including one or more channels;
a power input associated with the PCB coupled with the PDU housing and connectable to an external power source;
a plurality of cartridges each disposed in the one or more channels and removably connected to the PDU and in electrical communication with the power input, each of said cartridges supporting at least one power-related electrical component; and
a plurality of cartridge interfaces mounted to the PCB and configured to removably connect the plurality of cartridges to the PDU, wherein at least one of the plurality of cartridge interfaces includes one or more connectors extending toward its associated cartridge.

23. A power distribution unit (PDU), comprising:
an elongate PDU housing substantially enclosing an interior and including one or more channels separated from and extending longitudinally along a lateral side of the PDU housing interior;
at least one printed circuit board (PCB) within the one or more channels;
a power input associated with the PCB coupled with the PDU housing and connectable to an external power source; and
a plurality of interchangeable cartridges, each disposed in the channel and removably connected to the PCB and in electrical communication with the power input, each of said interchangeable cartridges supporting at least one power-related electrical component.

24. The PDU of claim 23 , further comprising a plurality of cartridge interfaces mounted to the PCB and configured to removably connect the plurality of cartridges to the PDU.

25. The PDU of claim 23 , wherein the interior and the one or more channels share a common wall.
