As a kind of car RF connector, automotive terminals are now very important. Automotive terminals are connectors of various harness processing with current and information transmission data in the whole vehicle, so there is a high demand for terminals on both sides of the electronic harness. Automotive terminals can be said to be the central nervous system connecting various household appliances and sensors, and undertake the daily task of current and information transmission. Therefore, if the waterproof of automotive terminal is not very good, it will lead to the car being invalid, and more serious short-circuit failure will lead to car damage and safety accidents. In this way, the waterproof characteristic of automotive terminal is very critical in the electrical control system of automotive vehicle， especially for the automotive terminals used in new energy development technology, the waterproof requirements are more serious and detailed. How is the air tightness and waterproof inspection of automotive terminals?

If it is necessary to carry out IP68 waterproof level detection for automotive terminals, air tightness and waterproof detection for automotive terminals is mainly to detect whether there is leakage in the production and manufacture of needles, casings and sealants. The air tightness and waterproof detector can be selected for the purpose of air tightness and waterproof detection for automotive terminals. First, the automotive terminal air tightness and waterproof testing mold shall be customized according to the terminal structure, and the terminal shall be put into the mold. After the upper and lower molds are closed, the automotive terminal can be completely sealed. Then, the automotive terminal air tightness and waterproof testing work clothes shall be made, and connected to the testing port of the automotive terminal air tightness and waterproof testing experimental equipment, which can be tested gradually.

Automotive terminal air tightness and waterproof testing mechanical equipment takes compressed gas as the medium, which can well complete high-quality testing. As the detected substance is gas, the air cannot cause harm and interference to the equipment. Secondly, because the molecular structure of gas is smaller than that of water, small leakage can be detected. The actual operation is very simple and can improve the efficiency.
