Information

There are many types of new energy vehicle connectors, such as energy storage connectors, high-voltage interlock connectors, charging guns, etc., so they all have some commonality; since new energy vehicles are "green" vehicles, the connectors also require Green and environmental protection, among them, the most important thing is the safety issue, because the working voltage range is 400V~600V, the working current range reaches 50A~300A or even higher, considering that the operator will inevitably come into contact with the car during the entire life cycle In the engine compartment, the need for high standards of protection against electric shock is obvious. In addition, at such high power, electromagnetic interference is another important issue. Also, arcing will be generated during the connector plugging operation, which will seriously endanger the Electrical connections and electronic equipment, and may cause automobile combustion, all require special design and development of connectors.

The high-performance requirements of new energy vehicle connectors mainly rely on strict design specifications. For example, in the case of exposure, it is necessary to prevent high voltage from breaking down the air. This requires a certain air gap to be reserved in the case of high voltage and high current. The temperature rise cannot exceed the rated value. When selecting the shell material, weight, strength and whether it is easy to process should be considered, and how to maintain the stability of the material properties of the connector terminals at different temperatures and how to ensure the necessary electrical conductivity need to be considered.
