AI Technical Summary

Problems solved by technology

[0002] With the increasing popularity of new energy vehicles, equipment and facilities for powering new energy vehicles have also developed. The connector assembly on new energy vehicles must meet the requirements of driving high-power motors, and the transmission current is relatively large. , the diameter of the high-voltage cable on the connector assembly also increases accordingly, and the assembly on the vehicle body can only be installed manually, which wastes labor costs and time costs

[0003]In addition, in the process of normal use, the high-voltage cables will flow a very large current, so the high-voltage cables and the connecting joints will generate a lot of heat, due to the heat If it is too large, it will lead to high temperature, and the connection position of the high-voltage cable and the surrounding connectors and fixing parts will fail due to high temperature, which will affect the normal use of the high-voltage device, cause short circuit and open circuit, and even cause electric shock, which is life-threatening

[0004] Due to the high current, high-voltage cables will generate strong electromagnetic interference. In order to reduce the influence of electromagnetic interference, high-voltage cables usually use shielding nets for electromagnetic interference shielding At present, the commonly used shielding net is made of metal wire. It is necessary to add a shielding braiding machine to the cable production equipment. The equipment is expensive and occupies a large area, which leads to the high price of shielded cables for connectors.

And the current shielding technology for the connector is not particularly perfect, which will cause the electrical appliances in the car to be interfered and unable to use

[0005] There is still no practical solution to the above problems. Therefore, the automotive electrical technology field urgently needs a connector assembly with a smaller wire diameter, lower cable heat generation, and automatic production and assembly.
