Wire harness tester for testing of aircraft multi-port cables

1. Application background.

Spacecraft cables are generally tested after processing is completed, mainly to verify the correctness of cable development. In other stages, there are also many requirements for cable testing in the spacecraft test system: the corresponding cables need to be tested before the cable is used, after the test transfer, before the start of large-scale experiments, and before the launch site test.

The performance testing of spacecraft cables is mainly divided into cable conduction resistance testing, insulation resistance testing, etc.

Traditional spacecraft cable testing methods are mainly manual testing. Manual cable testing requires two people to operate, using digital multimeters, insulation resistance meters and other corresponding testing instruments to test the cables. However, the shortcomings of traditional testing methods are: 1. Low efficiency; 2. Poor reliability and safety; 3. Test results need to be recorded manually; 4. Multi-port cable testing is difficult;

2. Antai wire harness tester.

Antai wire harness tester aims at the problem of multi-port complex cable testing and makes up for the shortcomings of traditional cable testing methods. It has the following advantages: fast detection speed, suitable for rapid detection of test cables; strong versatility, can be used for testing of various general cables; It is highly intelligent and can be used for various complex cable detection; it has high reliability and accurate detection data; it can expand the slave machine, and the master machine is followed by the slave machine, which can be used for cable detection of more ports, and can be expanded to up to 4096 test points. ; The test results can be saved and printed in time, and the results can be compared to facilitate data review; the human-computer interaction is good, making it convenient for the inspection personnel to operate and intuitively display the cable test results.

3. System composition of Antai wire harness tester.

Antai wire harness tester system is mainly composed of host computer, test host, slave machine (distribution machine), power bus, communication bus and transfer cable. The upper computer and the test host are integrated in a chassis, collectively referred to as the host computer. The slave computer (distributor) is connected to the vehicle under test cable through an adapter cable for interface data collection.

4. Advantages of Antai wire harness tester

1. To avoid human errors, the Antai wire harness tester is all operated on the computer from testing to saving the results, which can ensure the elimination of human errors.

2. Ability to perform insulation testing. This is a step that cannot be performed by manual conduction by workers. Insulation is a necessary test step in cable detection. The tester can complete tests that cannot be performed by manual conduction.

3. Save testing time and improve work efficiency. It can achieve rapid batch measurement, and the efficiency is much higher than manual continuity testing.

5. Summary

Antai wire harness tester has high testing accuracy, fast speed and high safety, which reduces the cost of cable testing and reduces the workload of testers. One tester can detect various indicators of the entire cable, not only It significantly improves the automation level of testing, improves testing efficiency, and provides assistance for daily debugging and maintenance of equipment under test.
