Abstract

An electrical system may include a first electrical connector configured to be coupled to an electrical panel, a second electrical connector configured to be coupled to a testing device that is configured to test components coupled to the electrical panel, and a retaining harness assembly that removably connects to the first and second electrical connectors to maintain a secure mating relationship between the first and second electrical connectors.

First claim

What is claimed is:

1. An electrical system, comprising:
a first electrical connector configured to be coupled to an electrical panel;
a second electrical connector configured to be coupled to a testing device that is configured to test a component coupled to the electrical panel; and
a retaining harness assembly that removably connects to the first and second electrical connectors to maintain a secure mating relationship between the first and second electrical connectors, wherein the retaining harness assembly comprises (a) a rear wall connected to opposed lateral walls, wherein a connecting chamber is defined between the rear wall and the lateral walls, (b) a lower ledge separated from an upper ledge by a flange-receiving slot, wherein a flange of the second electrical connector is received and retained within the flange-receiving slot, wherein the lower ledge exerts a first retaining force into the flange; and (c) a retaining collar that secures around a portion of a backplane of the second electrical connector and abuts into a torque ring of the second electrical connector, wherein the retaining collar exerts a second retaining force into the torque ring.

2. The electrical system of claim 1 , wherein the first and second electrical connectors are configured to mate together in a linear, non-rotational direction.

3. The electrical system of claim 1 , wherein one or both of the first and second electrical connectors is devoid of a threaded connection interface.

4. The electrical system of claim 1 , wherein the retaining harness assembly biases the first electrical connector toward the second electrical connector.

5. The electrical system of claim 1 , wherein the retaining harness assembly further comprises one or more lead-in walls that connect to the flange-receiving slot.

6. The electrical system of claim 1 , wherein the retaining collar comprises one or more recessed areas configured to conform to a portion of an outer surface of the backplane.

7. The electrical system of claim 1 , wherein the opposed lateral walls are configured to be deflected into an open position in order to remove the retaining harness assembly from the first and second electrical connectors.

8. An electrical system, comprising:
a shipside connector coupled to an electrical panel of a galley within an aircraft;
a test connector coupled to a testing device that is configured to test a component coupled to the electrical panel; and
a retaining harness assembly that removably connects to the shipside and test connectors to maintain a secure mating relationship between the shipside and test connectors, wherein the retaining harness assembly comprises: (a) a retainer housing secured around a portion of a backshell of the shipside connector; (b) a spring override ring secured around a portion of the retainer housing and operatively coupled to a torque ring of the shipside connector; and (c) a biasing spring having a first end retained by the retainer housing, wherein the spring override ring is configured to be rotated between a first position in which the biasing spring biases the spring override ring into the torque ring, and a second position in which the biasing spring is compressed toward the retainer housing, wherein compression of the biasing spring toward the retainer housing allows the torque ring to be rotated.

9. The electrical system of claim 8 , wherein the shipside and test connectors are configured to mate together in a linear, non-rotational direction, wherein one or both of the shipside and test connectors is devoid of a threaded connection interface, wherein the retaining harness assembly biases the test connector toward the shipside connector.

10. The electrical system of claim 8 , wherein the retaining harness assembly comprises one or more deflectable portions that are configured to be deflected into an open position in order to disconnect the retaining harness assembly from the shipside and test connectors.

11. An electrical system, comprising:
a first electrical connector configured to be coupled to an electrical panel;
a second electrical connector configured to be coupled to a testing device that is configured to test a component coupled to the electrical panel; and
a retaining harness assembly that removably connects to the first and second electrical connectors to maintain a secure mating relationship between the first and second electrical connectors wherein the retaining harness assembly comprises: (a) a securing strap that abuts into a flange of the second electrical connector, wherein the securing strap exerts a first retaining force into the flange, and (b) at least one retaining arm having a protuberance that abuts into a backplane of the first electrical connector and is supported over an edge of a torque ring, wherein the protuberance exerts a second retaining force into the torque ring.

12. The electrical system of claim 11 , wherein the at least one retaining arm is configured to be deflected into an open position in order to disconnect the retaining harness assembly from the first and second electrical connectors.

13. The electrical system of claim 11 , wherein the first and second electrical connectors are configured to mate together in a linear, non-rotational direction.

14. The electrical system of claim 11 , wherein one or both of the first and second electrical connectors is devoid of a threaded connection interface.

15. The electrical system of claim 11 , wherein the retaining harness assembly biases the first electrical connector toward the second electrical connector.

16. An electrical system, comprising:
a first electrical connector configured to be coupled to an electrical panel;
a second electrical connector configured to be coupled to a testing device that is configured to test a component coupled to the electrical panel; and
a retaining harness assembly that removably connects to the first and second electrical connectors to maintain a secure mating relationship between the first and second electrical connectors, wherein the retaining harness assembly comprises: (a) a retainer housing secured around a portion of a backshell of the first electrical connector, (b) a spring override ring secured around a portion of the retainer housing and operatively coupled to a torque ring of the first electrical connector, and (c) a biasing spring having a first end retained by the retainer housing.

17. The electrical system of claim 16 , wherein the spring override ring is configured to be rotated between a first position in which the biasing spring biases the spring override ring into the torque ring, and a second position in which the biasing spring is compressed toward the retainer housing, wherein compression of the biasing spring toward the retainer housing allows the torque ring to be rotated.

18. The electrical system of claim 16 , wherein the retainer housing comprises a shroud that retains the first end of the biasing spring.

19. The electrical system of claim 16 , wherein the spring override ring connects to the torque ring through a ratchet interface.

20. The electrical system of claim 16 , wherein at least a portion of the spring override ring is configured to cooperate with one or more tracks formed in the retainer housing to vary a compression of the biasing spring as the spring override ring is rotated relative to the retainer housing and the torque ring.

21. The electrical system of claim 16 , wherein the first and second electrical connectors are configured to mate together i
