Abstract

Test system and methods for testing a wiring harness. In one embodiment, a remote tester of the test system includes a connector member comprising a terminal end having one or more terminals configured to mate with terminals in an electrical connector of the wiring harness, and a tester control member integrated on a back end. The tester control member includes a housing that protrudes from the back end of the connector member, test circuitry electrically coupled to the terminals of the connector member, a wireless transceiver that communicates with a central controller to receive a test program, and a battery. The test circuitry performs a test on the wiring harness based on the test program, and reports test results to the central controller.

First claim

The invention claimed is:

1. A wiring harness test system, comprising:
a plurality of remote testers configured to couple with electrical connectors of a wiring harness; and
a charging station comprising a plurality of docking ports, wherein each of the docking ports includes:
a charging connector configured to couple with a charging port on one of the remote testers to charge the one of the remote testers; and
a test selection indicator configured to indicate whether the one of the remote testers is selected for a test process on the wiring harness;

wherein the charging station further comprises a charging station controller configured to receive information on the remote testers scheduled for the test process on the wiring harness, and to activate the test selection indicator at one or more of the docking ports to indicate the remote testers scheduled for the test process.

2. The wiring harness test system of claim 1 , further comprising:
a central controller configured to communicate wirelessly with the remote testers to transmit at least one test program to the remote testers to perform the test process on the wiring harness, and to receive test results from the remote testers;
wherein the charging station controller is configured to communicate with the central controller to receive the information on the remote testers scheduled for the test process on the wiring harness.

3. The wiring harness test system of claim 2 , wherein:
the charging station controller is configured to communicate with the central controller through wireless signals.

4. The wiring harness test system of claim 2 , wherein:
the remote testers are configured to communicate with the central controller on different frequencies.

5. The wiring harness test system of claim 2 , wherein:
the remote testers are configured to communicate with the central controller on a common frequency, and are individually addressable.

6. The wiring harness test system of claim 1 , wherein:
the test selection indicator includes a light.

7. The wiring harness test system of claim 1 , wherein each of the remote testers includes:
a connector indicator configured to display an electrical connector identifier indicating one of the electrical connectors of the wiring harness that is targeted for coupling with a remote tester.

8. The wiring harness test system of claim 1 , wherein each of the docking ports further includes:
a battery level indicator configured to indicate a battery level of a battery in the one of the remote testers.

9. The wiring harness test system of claim 8 , wherein:
the battery level indicator includes one or more lights.

10. The wiring harness test system of claim 1 , wherein:
the wiring harness comprises a wiring harness of an aircraft.

11. A wiring harness test system, comprising:
a plurality of remote testers configured to couple with electrical connectors of a wiring harness;
a central controller configured to communicate wirelessly with the remote testers to transmit at least one test program to the remote testers to perform a test process on the wiring harness, and to receive test results from the remote testers; and
a charging station comprising a plurality of docking ports, wherein each of the docking ports includes:
a charging connector configured to couple with a charging port on one of the remote testers to charge the one of the remote testers; and
a test selection indicator configured to indicate whether the one of the remote testers is selected for the test process;

wherein the charging station further comprises a charging station controller configured to communicate with the central controller to receive information on the remote testers scheduled for the test process, and to activate the test selection indicator at one or more of the docking ports to indicate the remote testers scheduled for the test process.

12. The wiring harness test system of claim 11 , wherein:
the remote testers are configured to pair with the central controller, and to activate a pairing indicator when paired with the central controller.

13. The wiring harness test system of claim 11 , wherein each of the remote testers includes:
a connector indicator configured to display an electrical connector identifier indicating one of the electrical connectors of the wiring harness that is targeted for coupling with a remote tester.

14. A method of testing a wiring harness, the method comprising:
docking, at a charging station, a plurality of remote testers configured to couple with electrical connectors of the wiring harness, wherein the charging station includes a plurality of docking ports each including a charging connector configured to couple with a charging port on one of the remote testers to charge the one of the remote testers, and a test selection indicator configured to indicate whether the one of the remote testers is selected for a test process on the wiring harness;
selecting remote testers of the plurality for the test process on the wiring harness;
receiving, at the charging station, information on the selected remote testers for the test process; and
activating the test selection indicator at one or more of the docking ports to indicate the selected remote testers for the test process.

15. The method of claim 14 further comprising:
pairing the selected remote testers for the test process with a central controller;
coupling the selected remote testers for the test process to the electrical connectors of the wiring harness; and
performing the test process on the wiring harness.

16. The method of claim 15 wherein coupling the selected remote testers for the test process to the electrical connectors of the wiring harness comprises:
transmitting an electrical connector identifier from the central controller to each of the selected remote testers indicating a respective one of the electrical connectors of the wiring harness that is targeted for coupling with a respective one of the selected remote testers; and
displaying the electrical connector identifier on a connector indicator at each of the selected remote testers.

17. The method of claim 15 wherein performing the test process comprises:
transmitting a test program from the central controller to the selected remote testers via wireless signals;
performing, at the selected remote testers, a test on the wiring harness based on the test program;
reporting test results for the test process from the selected remote testers to the central controller via wireless signals; and
verifying, at the central controller, a condition of the wiring harness based on the test results.

18. The method of claim 15 wherein:
the test process is performed before over-braiding of the wiring harness.

19. The method of claim 15 wherein:
the test process is performed after over-braiding of the wiring harness.

20. The method of claim 15 wherein:
the test process is performed while the wiring harness is installed in an aircraft.
