Problems solved by technology

[0004] In the prior art, the connector passes a large current by increasing the terminal volume, contact area and wire cross-sectional area, which will inevitably lead to an increase in the weight and volume of the connector, the weight and volume of the vehicle wiring harness assembly, and the increase in production costs. At the same time, the layout space of the whole vehicle is limited
[0005] In addition, the connector conducts high voltage and high current, and the connector terminals and wires heat up seriously. The heat generated inside the connector cannot be dissipated, which will cause safety problems such as increased power loss of the connector, ablation, melting of terminals and shells, and overheating of wires.

Abstract

The invention discloses a connector with the cooling function. The connector comprises a socket and a plug matching the socket. A female terminal and a male terminal are arranged at the plug. Besides,the connector also includes a first cooling pipe and a second cooling pipe; and cooling mediums flow through the first cooling pipe and the second cooling pipe. The first cooling pipe is arranged atthe outer periphery of the female terminal to reduce the temperatures of the female terminal and the male terminal; the second cooling pipe penetrating the socket and the plug is used for reducing thetemperature of a cable connected to the plug. With the connector, the temperatures of the terminals are monitored in real time; the temperatures of the terminal and the cable are reduced effectively;heavy charging currents can flow through the connector; the service lives of the connector and the cable are prolonged; and the stability, reliability and safety of the connector in the vehicle application are improved.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a connector with a cooling function and an electric vehicle. Background technique [0002] With the development of fast charging technology and high-power drive motors for electric vehicles, higher requirements are placed on the performance of connectors and cables. Connectors and cables, as important components of electric vehicle charging systems, determine the stability, reliability and safety of connectors in vehicle applications. [0003] Fast charging of electric vehicles uses high voltage and high current to fully charge electric vehicles in a short time. [0004] In the prior art, the connector passes a large current by increasing the terminal volume, contact area and wire cross-sectional area, which will inevitably lead to an increase in the weight and volume of the connector, the weight and volume of the vehicle wiring harness assembly, and the increase ...
