At this stage, in order to ensure the assembly and the high integration of vehicle electrical functions, and to meet the development of a new intelligent electrical appliance architecture, the connector interface is generally selected with a high degree of integration (not only to transmit high current and high power power, but also It also transmits low-voltage and low-current analog signals), and selects different levels of connection structures for different functions and different positions to ensure that the service life of the connector cannot be lower than that of a normal vehicle, and the power supply must be guaranteed within the allowable error range. And the stable transmission of control signals; the connectors are connected through terminals, and the male and female terminals are made of metal conductive materials, and the quality of the terminal connection directly affects the reliability of the electrical functions of the vehicle.
