How is the air tightness and waterproof test of automotive terminals done?
Release time:2022-05-21Views:2677


Automotive terminal is very important as car connector. Automotive terminal is the current and signal transmission connector in various electronic harnesses throughout the car, so there are high requirements for the terminals at both ends of the harness. It can be said that the automotive terminal is a nervous system, which connects various appliances and sensors of the car and carries the task of current and signal transmission. Therefore, if the waterproof performance of the vehicle terminal is not good, it will lead to vehicle function failure, and in serious cases, it will lead to short circuit and vehicle burning accidents. In this way, in the waterproof of automotive electrical system, the waterproof performance of automotive terminal is particularly important. Especially for the new energy vehicle terminal, waterproof requirements are relatively strict, so how to carry out the air tightness and waterproof test of the automotive terminal?


To test the IP68 protection level of automotive terminals, the air tightness and waterproof test of automotive terminals is mainly to test whether water enters the shell and the processing position of sealant. Air tightness and waterproof tester can be used to realize the air tightness and waterproof test of automotive terminal. In order to realize the air tightness and waterproof test of automotive terminal, the air tightness and waterproof test mold of automotive terminal is first customized according to the terminal structure, and the terminal is put into the mold. After the upper and lower dies are closed, the automotive terminals can be completely sealed. Automotive terminal air tightness and waterproof test equipment is a direct test method with compressed air as the medium. Because the test medium is air, the nondestructive test can be achieved very well, and the air will not cause damage and affect the products. Secondly, since air molecules are smaller than water molecules, very small leakage efficiency can be detected.
