The invention provides a charging connector, an electric vehicle and a charging pile, and relates to the technical field of charging. The charging connector comprises a shell, a charging terminal and a cooling box, wherein the charging terminal is used for being connected with a lead wire, the cooling box is made of a heat conduction material, the charging terminal and the cooling box are both fixedly connected with the shell in the shell, the charging terminal is in heat conduction connection with the surface of the cooling box, a cooling medium cavity is formed in the cooling box, and the surface of the cooling medium cavity is provided with a concave-convex structure. The electric vehicle and the charging pile both comprise the charging connector. According to the charging connector, the electric vehicle and the charging pile provided by the invention, through the concave-convex structure on the surface of the cooling medium cavity, the contact surface of the cooling medium cavity and the cooling medium is increased, and the cooling effect on the charging terminal can be improved.
Description
technical field [0001] The invention relates to the technical field of charging, in particular to a charging connector, an electric vehicle and a charging pile. Background technique [0002] The charging connectors are respectively arranged on the power supply equipment and the equipment to be charged, so that the batteries in the power supply equipment and the equipment to be charged are connected to each other for charging. With the development of large power consumption equipment such as electric vehicles, the demand for fast charging is increasing. In order to improve the charging efficiency, it is necessary to increase the charging current. However, the greater the charging current, the more heat generated during the charging process, and the high temperature generated by the charging connector due to the high current will bring great safety hazards. [0003] In the prior art, the charging connector often includes a housing and a charging terminal. The charging termina...
