Abstract

A power connector assembly includes a power rail having a power supply circuit being configured to be mounted within an equipment cabinet and a sliding power connector configured to be terminated to a host circuit board. The sliding power connector has a power contact electrically connected to the power supply circuit of the power rail. The sliding power connector is configured to be slid along the power rail as an equipment rack holding the circuit board is opened and closed during an extension cycle of the equipment rack. The power contact maintains electrical connection with the power rail during the entire extension cycle.

First claim

What is claimed is:

1. A power connector assembly comprising:
a power rail configured to be mounted within an equipment cabinet, the power rail having a power supply circuit; and
a sliding power connector configured to be terminated to a host circuit board, the sliding power connector including a housing defining a track receiving the power rail, the track guiding movement of the sliding power connector along the power rail, the sliding power connector having a power contact electrically connected to the power supply circuit of the power rail, the sliding power connector configured to be slid along the power rail as an equipment rack holding the circuit board is opened and closed during an extension cycle of the extendible rack, the power contact maintaining electrical connection with the power rail during the entire extension cycle.

2. The power connector assembly of claim 1 , wherein the sliding power connector moves relative to the power rail.

3. The power connector assembly of claim 1 , wherein the track having a first rail and a second rail, the first rail engaging a first edge of the power rail and the second rail engaging a second edge of the power rail to fix a lateral position of the sliding power connector relative to the power rail.

4. The power connector assembly of claim 1 , wherein the power rail is elongated along a power rail axis parallel to a sliding direction of the sliding power connector.

5. The power connector assembly of claim 1 , wherein the sliding power connector includes a plurality of the power contacts.

6. The power connector assembly of claim 5 , wherein the power contacts are arranged in a first set and in a second set, the power contacts in the first set facing in a first direction, the power contacts in the second set facing in an opposite second direction.

7. The power connector assembly of claim 1 , wherein the sliding power connector includes a wiper engaging the power rail to wipe the power rail as the sliding power connector is moved along the power rail.

8. The power connector assembly of claim 1 , wherein the power rail is planar and oriented horizontally and parallel to the host circuit board, the host circuit board being oriented horizontally and non-coplanar with the power rail, the sliding power connector being positioned between the power rail and the host circuit board.

9. The power connector assembly of claim 1 , wherein the power rail is planar and oriented vertically and perpendicular to the host circuit board, the host circuit board being oriented horizontally.

10. The power connector assembly of claim 1 , wherein the power rail includes a cathode and an anode, the power contact defining a cathode contact electrically connected to the cathode of the power rail, the sliding power connector including an anode contact electrically connected to the anode of the power rail.

11. A communication system comprising:
an equipment cabinet having a chassis holding communication equipment, the equipment cabinet having a power supply;
a power rail held by the chassis of the equipment cabinet, the power rail having a power supply circuit electrically connected to the power supply; and
an equipment rack held by the chassis, the equipment rack being slidable during an extension cycle between closed and open positions, the equipment rack including a host circuit board having powered electrical components terminated thereto, the equipment rack including a sliding power connector terminated to the host circuit board, the sliding power connector having a housing defining a track receiving the power rail, the track guiding movement of the sliding power connector along the power rail, the sliding power connector having a power contact electrically connected to the power supply circuit of the power rail, the sliding power connector configured to be slid along the power rail as the equipment rack is moved between the closed and open positions during the extension cycle, the power contact maintaining electrical connection with the power rail during the entire extension cycle.

12. The communication system of claim 11 , wherein the equipment rack includes an extendable drawer holding the host circuit board.

13. The communication system of claim 11 , wherein the equipment rack is located above the power rail and slides along the power rail.

14. The communication system of claim 11 , wherein the sliding power connector moves relative to the power rail.

15. The communication system of claim 11 , wherein the power rail is elongated along a power rail axis parallel to a sliding direction of the sliding power connector.

16. A communication system comprising:
an equipment cabinet having a chassis holding communication equipment, the equipment cabinet having a power supply;
a power rail held by the chassis of the equipment cabinet, the power rail having a power supply circuit electrically connected to the power supply; and
an equipment rack held by the chassis, the equipment rack being slidable during an extension cycle between closed and open positions, the equipment rack including a host circuit board having powered electrical components terminated thereto, the equipment rack including a sliding power connector terminated to the host circuit board, the sliding power connector having a housing holding a power contact, the housing being mounted to the host circuit board, the housing having a track receiving the power rail, the power contact being electrically connected to the power supply circuit of the power rail, the sliding power connector being slid along the power rail with the power rail being guided through the track as the equipment rack is moved between the closed and open positions during the extension cycle, the power contact maintaining electrical connection with the power rail during the entire extension cycle.

17. The communication system of claim 16 , wherein the sliding power connector moves relative to the power rail.

18. The communication system of claim 16 , wherein the power rail is elongated along a power rail axis parallel to a sliding direction of the sliding power connector.
