      With the development of the new energy vehicle industry and the demand for the performance of new energy vehicles, the processing of automobile electronic wiring harness has changed from a simple power line to a signal line that can both meet the energy supply and complete various functional molds. Therefore, in order to ensure the quality of the car and ensure the safety of consumption and driving, manufacturers need to carry out air tightness tests in the factory. How to stop the new energy vehicle wire harness air tightness detection? What testing equipment is used to complete the new energy vehicle wire harness air tightness detection?

      Difficulty of new energy vehicle wire harness air tightness detection

      New energy vehicle wiring harness is mainly composed of wire, adapter, winding belt and other auxiliary data. It is the carrier that controls automobile electrical signal, has complex structure and diversified function. And the parts to be tested are not complete and identical and the air tightness requirements are complete and different. In order to solve the difficulties mentioned above, Goel Technology optimized the wire harness air tightness detector for new energy vehicles based on the characteristics of the wire harness and the original air tightness detection instrument. The new energy vehicle wire harness air tightness tester is fundamentally the same as the conventional air tightness tester, the difference lies in the test fixture (tooling).

      Because the wire harness is long and irregular, it is not easy to fix, so when stopping the test, it is necessary to use the corresponding custom test die stop fix to stop the air tightness test of the wire harness. Will need to stop air tightness test harness testing tool is put in the custom mold, then use the new energy automotive wiring harness tightness tester for wiring harness inflatable, then after wiring harness air tightness testing equipment of precise pressure sensor of changes to generate electrical signals and transmitted to the detection system, finally, after a series of calculation, can draw gas leakage value, The sealing performance and IP waterproof grade of the wire harness are tested according to the leakage value. This test method is not affected by the type of wire harness and waterproof grade, and can be matched with different molds (customized test fixture) and the parameters of the wire harness air tightness detector set separately, to complete the different wire harness used for testing, very suitable for the full line leakage test.
