In recent years, with the general improvement of people's living conditions, cars are no longer a "luxury" that only the rich can afford. They have entered thousands of households. People have higher and higher requirements for 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-car fiber optic cable network, ABS system, etc. As the internal structure of the car becomes more and more complicated, more and more car connectors are required. It is estimated that the number of electronic connectors in automobiles will be as high as 600~1000 per vehicle in the future, and the types of automobile 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.
