The function of the connector for new energy vehicles is mainly to ensure the high-voltage interconnection system of the whole vehicle, that is, to build a bridge where the internal circuit is blocked or isolated so that the current flows. The composition of connectors for new energy vehicles can generally be divided into three parts: auxiliary structures such as shells and seals, insulating parts, and conductive contact pairs. The functions of connection and conduction can be achieved through the plugging and mutual cooperation between the plug sheath and the socket sheath. High-voltage connectors are mainly used in high-voltage and high-current circuits of new energy vehicles, and act simultaneously with conductive cables to transmit the energy of battery packs to various components in the vehicle system through different electrical circuits, such as battery packs, motor controllers, DCDC Body power units such as converters and chargers.
