Abstract

Apparatuses and devices are provided that allow for a power input cord to be placed in two or more different orientations relative to a power distribution unit. A power distribution unit may be provided with one or more input cord assemblies that allow an input cord to be swiveled such that the cord exits an outside plane of the power distribution unit at a different angle. Such an assembly allows a power distribution unit to be placed in an equipment rack and coupled with an input power source in a flexible and convenient manner. Clearances and dimensions of equipment racks may be modified to provide enhanced space usage, efficiency, and/or density in a facility.

First claim

We claim:

1. A power input apparatus, comprising:
an input power cord that includes multiple conductors for providing power to a power distribution device from a power source;
a housing having an aperture extending through a front portion and a generally orthogonal end portion of the housing through which the input power cord passes from an exterior of the power distribution device to an interior of the power distribution device, wherein the end portion is substantially perpendicular to a longitudinal axis of the power distribution device; and
a rotational member coupled to the housing and secured to the input power cord, including first and second sections configured to apply pressure to the input power cord when the sections are joined together;
wherein the rotational member is configured to enable the input power cord to pivot between a first position where the input power cord is substantially aligned with the longitudinal axis of the power distribution device and a second position where the input power cord is substantially perpendicular to the longitudinal axis.

2. The apparatus of claim 1 , further comprising: an input power cord release mechanism coupled to the housing and releasably coupled to the rotational member to enable the rotational member to selectively rotate within the housing.

3. The apparatus of claim 2 , wherein the input power cord release mechanism includes a pin that is engageable with the input power cord release mechanism.

4. The apparatus of claim 3 , wherein the rotational member includes one or more notches or apertures that are engageable with at least a portion of the pin to secure the rotational member from rotation and to secure the input power cord from pivoting.

5. The apparatus of claim 1 , wherein the exit point of the input power cord from the rotational member is oriented such that it minimizes movement of the conductors within the power distribution device.

6. The apparatus of claim 1 , wherein the input power cord comprises a polyphase power input cord.

7. The apparatus of claim 1 , wherein the housing comprises modular mounting tabs that may be secured to another module of a power distribution device.

8. The apparatus of claim 1 , further comprising:
a barrier located at a first end of the housing that is distal to other portions of the power distribution device, the barrier configured to prevent passage of objects or materials through the first end.

9. A power distribution unit, comprising:
a power distribution unit housing;
a plurality of power outlets disposed in at least one face of the power distribution unit housing; and
a power input module, comprising:
an input power cord that includes multiple conductors for providing power to the power distribution unit from a power source;
a power input module housing that is mateable with the power distribution unit housing, the power input module housing having an aperture extending through generally orthogonal front and end portions of the input module housing through which the input power cord passes from an exterior of the power distribution unit to an interior of the power distribution unit, wherein the end portion is substantially perpendicular to a longitudinal axis of the power distribution unit; and
a rotational member coupled to the power input module housing and secured to the input power cord, including first and second sections configured to apply pressure to the input power cord when the sections are joined together;
wherein the rotational member is configured to enable the input power cord to pivot between a first position where the input power cord is substantially aligned with the longitudinal axis of the power distribution unit and a second position where the input power cord is substantially perpendicular to the longitudinal axis.

10. The power distribution unit of claim 9 , wherein the power input module further comprises:
an input power cord release mechanism coupled to the power input module housing and releasably coupled to the rotational member to enable the rotational member to selectively rotate within the power input module housing.

11. The power distribution unit of claim 10 , wherein the input power cord release mechanism includes a pin that is engageable with the rotational member.

12. The power distribution unit of claim 11 , wherein the rotational member includes one or more notches or apertures that are engageable with at least a portion of the pin to secure the rotational member from rotation and to secure the input power cord from pivoting.

13. The apparatus of claim 1 , further comprising a clamp gate positioned between one of the first and second sections and the input power cord.

14. The apparatus of claim 2 , wherein the rotational member includes one or more pairs of notches, and wherein the release mechanism includes a lever having a pair of hooks configured to engage the one or more pairs of notches.

15. The power distribution unit of claim 9 , further comprising a clamp gate positioned between one of the first and second sections and the input power cord.

16. The power distribution unit of claim 10 , wherein the rotational member includes one or more pairs of notches, and wherein the release mechanism includes a lever having a pair of hooks configured to engage the one or more pairs of notches.

17. A power distribution unit, comprising:
a power distribution unit housing having a longitudinal axis;
one or more power outlets disposed in the power distribution unit housing;
an input power cord for providing power to the one or more power outlets; and
a rotational member coupled to the power distribution unit housing and including first and second sections configured to apply pressure to the input power cord when the sections are joined together, thereby securing the input power cord to the rotational member;
wherein the rotational member is configured to enable the input power cord to pivot with respect to the power distribution unit housing between a first position where the input power cord is substantially aligned with the longitudinal axis and extends through an end portion of the power distribution unit housing, and a second position where the input power cord is oriented at an angle of approximately 90 degrees with respect to the longitudinal axis and extends through a front portion of the power distribution unit housing.

18. The power distribution unit of claim 17 , further comprising a clamp gate positioned between one of the first and second sections and the input power cord.

19. The power distribution unit of claim 17 further comprising a latch coupled to the power distribution unit housing and releasably engaged with the rotational member to enable the rotational member to selectively rotate with respect to the power distribution unit housing.

20. The power distribution unit of claim 19 , wherein the rotational member includes one or more pairs of notches, and wherein the latch includes a lever having a pair of hooks configured to engage the one or more pairs of notches.

21. A power input apparatus, comprising:
an input power cord that includes multiple conductors for providing power to a power distribution device from a power source;
a housing having an aperture extending through two generally orthogonal side portions of the housing through which the input power cord passes from an exterior of the power distribution device to an interior of the power distribution device;
a rotational member coupled to the housing and secured to the input pow
