Connector assembly with liquid cooling function and vehicle

Abstract

The invention discloses a connector assembly with a liquid cooling function and a vehicle, the connector assembly comprises at least one electric connection framework and a connector connected with the two ends of the electric connection framework, the periphery of the electric connection framework is sequentially sleeved with a first sleeve and a second sleeve, a first cavity is formed between the outer wall of the electric connection framework and the inner wall of the first sleeve, and a second cavity is formed between the outer wall of the second sleeve and the inner wall of the second sleeve. A second cavity is formed between the outer wall of the first sleeve and the inner wall of the second sleeve, and cooling liquid circulates in the first cavity and the second cavity. 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.

Description

technical field [0001] The invention relates to the technical field of automotive electrical appliances, and more particularly, to a connector assembly with a liquid cooling function and a vehicle. Background technique [0002] New energy vehicles are becoming more and more popular. During the normal use of new energy vehicles, the electric cables used for power transmission will flow through a very large current, so the cables and connecting joints will generate a lot of heat. Cause high temperature, cable connection position and surrounding connectors and fixings will fail due to high temperature, affecting the normal use of related devices, resulting in short circuits and open circuits, and even risk of electric shock, which is life-threatening. At the same time, due to the large current of the cables in the car, it will generate strong electromagnetic interference. In order to reduce the influence of electromagnetic interference, the transmission cable usually uses a shi...

Problems solved by technology

[0002] New energy vehicles are becoming more and more popular. During the normal use of new energy vehicles, the cables used for power transmission will flow through very large currents, so the cables and connectors will generate a lot of heat. Leading to high temperature, the cable connection position and the surrounding connectors and fixing parts will fail due to high temperature, affecting the normal use of related devices, causing short circuits and open circuits, and even causing electric shock hazards, which are life-threatening

At the same time, due to the high current of the cables in the car, strong electromagnetic interference will be generated. In order to reduce the influence of electromagnetic interference, the transmission cables usually use shielding nets to shield electromagnetic interference. Currently, the commonly used shielding nets are made of metal wires. As a result, shielding braiding machines need to be added to the cable production equipment. The equipment is expensive and occupies a large area, resulting in high prices for 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

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.
