New energy vehicle connector terminals--green|safety|connectivity|long-life new energy vehicles are 'green' vehicles, and the connector terminals are also required to be green. In terms of safety, the new energy vehicle connector has the ability to withstand up to 250A current and 600V voltage. The high standard of protection against electric shock is obvious. Under such high power, electromagnetic interference is another important issue. In addition, the plugging and unplugging operations of the connector will generate arcs, which will seriously harm the electrical connections and electronic equipment, and may cause the car to burn, all of which require the special design and development of the connector terminals. New energy vehicle connector terminals must meet their high-performance requirements mainly by strict design specifications. For example, to prevent high voltage from breaking down the air under exposure, a certain air gap needs to be reserved; under the condition of high voltage and high current, its temperature The increase cannot exceed the rated value; the weight, strength and ease of processing should be considered when selecting the shell material. How to maintain the stability of the material properties of the connector terminals at different temperatures and how to ensure the necessary conductivity needs to be considered. In terms of connectivity, with the continuous expansion of car entertainment systems, the importance of high-speed data transmission has become increasingly prominent. For example, on some models, a camera is installed on the reversing mirror, which allows the driver to have a wider field of view, which requires the connector to transmit more data. Sometimes a connector is needed to solve the problem of transmitting GPS signals and broadcast signals at the same time, which requires improving its data transmission capabilities. The connector also needs to withstand high temperature. The car engine is usually placed in front of the car. Although there is a firewall to protect it, some heat will be transferred, so the connector must be able to withstand high temperature. In addition, the'strict' requirements for automotive connector terminals are also reflected in their life. Generally, there are elastic elements in the connector, which will lose its function after a certain number of plugging and unplugging. Therefore, the service life is generally about 3-5 years. A car can be used for 10-20 years. Therefore, the service life of the car connector must be the same as that of the car. The service life is equivalent, and the requirements for the connector terminals are quite high.
