Abstract

The invention relates to a female plug, a male plug, and a high-voltage large-current connector equipped with the female plug and the male plug. The female plug comprises a sleeve part which has an inner end and an outer end. A limiting boss is arranged on the outer circumference of the sleeve part. The limiting boss is provided with a guide sidewall A and a guide sidewall B. the guide sidewall B is arranged perpendicular to the axial direction of the sleeve part. The inner end of the guide sidewall B and the guide sidewall A are in the circumferential direction of the sleeve part. The female plug is further provided with a second circumferential positioning part which matches with a first circumferential positioning part on the male plug to form a circumferential positioning structure, and the second circumferential positioning part and the limiting boss are circumferentially fixed. Through matching of the male plug and the female plug, convenient disassembly is achieved without reducing the reliability of connection.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, and in particular relates to a female connector, a male connector and a high-voltage and high-current electrical connector provided with the male connector and the female connector. Background technique [0002] High-voltage and high-current electrical connectors are important components of the electrical system of new energy vehicles. They are mainly used to realize electrical connections in places where large currents pass, such as inverters, motors, and batteries. In order to ensure the reliability of the connection, people often adopt more complicated means to realize the connection between the male connector and the female connector of the electrical connector, but this connection method is more troublesome to disassemble and will increase the time to pull out the connector. , prolonging the man-hours required for maintenance. Contents of the invention [0003] In order to o...
