Connector assembly with solid cooling medium and vehicle

Abstract

The invention discloses a connector assembly with a solid cooling medium and a vehicle, and the connector assembly comprises at least one electric connection skeleton and a connector connected with the two ends of the electric connection skeleton, and the periphery of the electric connection skeleton is sleeved with a protection shell with a shielding effect. And a solid or semi-solid cooling medium is at least partially filled between the outer wall of the electric connection framework and the inner wall of the protective shell. According to the connector assembly, the failure caused by high temperature generated by electrification of the electric connection framework and the connection terminals can be reduced, the diameter of the electric connection framework is reduced, the service life of the connector assembly is prolonged, the safety of a whole vehicle is improved, and meanwhile the effect of shielding electromagnetic interference is achieved.

Problems solved by technology

[0002] With the increasing popularity of new energy vehicles, the equipment and facilities for the electrical connection of new energy vehicles have also developed. The connector assembly on new energy vehicles must meet the requirements of fast transmission current, and the transmission current is relatively high. Large, the diameter of the cable on the connector assembly also increases, and the assembly on the vehicle body can only be installed manually, which wastes labor costs and time costs

[0003] In addition, during normal use, the cable of the new energy vehicle will flow a very large current, so the cable and the connecting joint will generate a lot of heat, which will lead to high temperature due to excessive heat, the connection position of the charging cable and the surrounding areas Connecting parts and fixing parts will fail due to high temperature, which will affect the normal use of the connector assembly, cause short circuit and open circuit, and even cause electric shock hazard, which is life-threatening

[0004] Due to the large current, the cables of new energy vehicles will generate strong electromagnetic interference. In order to reduce the influence of electromagnetic interference, the cables usually use shielding nets for electromagnetic interference shielding. Currently, the commonly used shielding nets are made of metal wires. , 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 the shielded cable of the connector assembly.

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 no practical solution to the above problems. Therefore, in the field of automotive electrical technology, there is an urgent need for a cable with a smaller diameter and lower calorific value, which can realize automatic production. and assembled connector assembly
