In recent years, with the general improvement of people's living conditions, cars are no longer a "luxury" that can only be driven by the rich, and they have entered thousands of households. People have higher and higher requirements for cars in terms of safety, comfort, environmental protection, intelligence, etc., and more and more automotive electronic products have been applied, such as car audio, GPS navigation, entertainment facilities, airbags, In-vehicle optical cable network, ABS system, etc. As the internal structure of automobiles becomes more and more complex, more and more automotive connectors are required. It is expected that the number of electronic connectors in future cars will be as high as 600~1000 per car, and the types of automotive connectors may also change. In the future, the market for automotive connectors will become larger and larger, and the development prospects are also very exciting.
