Connector performance requirements: included in the system-level specifications; for GM, Ford, and Chrysler, it is usually USCAR specification engine-related applications have relatively high vibration requirements; other OEMs generally have their standards (similar to USCAR); Trends: Device-side suppliers are responsible for the performance of mating-end connectors. Devices account for half of the board-fitting connector interface. Equipment suppliers are required to have good communication with mating-side information.
New energy vehicle connectors are one of the main categories of connectors. In recent years, with the development of new energy vehicles in the country, it has gradually moved away from traditional high-voltage and high-current, and low-voltage vehicle connectors. Compared with traditional high-voltage and high-current connectors, the working conditions of new energy automotive connectors are more complex and changeable, and the reliability of connectors is higher; compared with traditional low-voltage automotive connectors, due to the increase in voltage levels (current mainstream systems The voltage is higher than 300V DC), which increases the risk of electric shock injury to the human body, and has higher safety requirements for the connector; therefore, compared with the traditional low-voltage plug-in, the insulation and protection requirements of the product are improved.
The function of the new energy connector is to ensure the high-voltage interconnection system of the vehicle, that is, to build a bridge where the internal circuit is blocked or isolated so that the current can flow. The components of a general new energy vehicle connector can be divided into three parts: housing, sealing and other auxiliary structures, insulation, and conductive contact. The functions of connection and conduction are realized through the mating of the plug sheath and the socket sheath. High-voltage connectors are mainly used in high-voltage and high-current circuits of new energy vehicles. At the same time, they are used as conductive cables to transfer the energy of the battery pack through different courses, such as battery packs, motor controllers, and DCDC bulk power units such as converters and chargers.
