New energy vehicles refer to energy vehicles other than gasoline and diesel engines. For example: hybrid cars, hydrogen-powered cars, solar cars, fuel cell cars, etc. These cars have one thing in common-they have relatively low exhaust emissions, so they are also called "green cars". In order to ensure environmental protection, in addition to being more secure, the electrical connectors used must also be environmentally friendly.
These green cars have a working voltage range between 400V-600V and a working current range of 50A-300A or even higher. During the operation, the operation union will inevitably touch the engine compartment throughout the life cycle of the car, so a higher standard of protection against electric shock is required. In order to ensure safe operation and prevent automobile combustion, electrical connectors require special design and development.
New energy automotive electrical connectors first consider the weight, strength and ease of processing when selecting the shell material, and the stability of the material properties and electrical conductivity of the connector terminals at different temperatures need to be considered; secondly, to ensure high voltage and high current In this case, the temperature rise cannot exceed the rated value, so thermoplastic housings and silicone-sealed electrical connectors are often chosen because they can withstand extreme humidity and temperature.
Now the car entertainment system is constantly expanding. In order to give the driver a wider field of view, some models will install a camera on the reversing mirror, the car has a USB interface for data transmission, and so on. Sometimes an electrical connector is required to transmit GPS signals. With broadcast signal problems, the ability to transmit data needs to be improved.
Automotive engines are usually in the front of the car and generate heat. Even if protected by a firewall, there will still be heat conduction, which requires the electrical connector to have the advantage of withstanding high temperatures. The service life of the connector is usually 3-5 years, but the service life of the electrical connector on the car is the same as that of the car, that is, the shortest life time is 10 years. This requirement is quite high, and the material selected must have Advantages of high service life.
