The invention discloses a charging socket structure, a charging connection structure and an electric vehicle. The charging socket structure comprises a charging socket and a metal flange; a through hole is formed in the metal flange; the through hole is matched with the charging socket; the metal flange is fixedly connected with the charging socket through the through hole; the metal flange is used for making contact with a vehicle body; the charging socket comprises a first hole and a grounding terminal; the first hole is formed in the end part of the charging socket and is used for being matched with a grounding conductor in charging equipment of a charging plug; the grounding terminal comprises a first bent section, a connecting section and a second bent section; and the first bent section is arranged on the inner wall of the first hole, the second bent section is arranged on the outer side of the charging socket, the first bent section and the second bent section are connected through the connecting section, and the end, away from the connecting section, of the second bent section makes contact with the metal flange. The vehicle body can be grounded when the vehicle is charged, and the problems of too many charging connecting parts, complex assembly and high cost in the prior art are solved.
Description
technical field [0001] The present application relates to the technical field of charging, in particular to a charging socket structure, a charging connection structure and an electric vehicle. Background technique [0002] In order to protect the safety of electricity use, in the standard of electric vehicle charging connection, it is required that the charging interface must be grounded, and the grounding connection resistance and grounding overcurrent capability must match the charging current. The larger the charging current specification, the higher the grounding overcurrent capability requirement. Big. [0003] With the development of electric vehicles, in order to increase the charging speed of electric vehicles, the society has begun to research and develop high-power charging. The current of high-power charging is large, and the safety requirements are high. large ground conductor. [0004] The electric vehicle charging interface is the interface between the vehic...
