[0002] The battery swap connector is an important component in new energy battery swap models. The battery swap connector is mainly used to establish an electrical connection between electric vehicles and battery swap stations, solving the problem of electric vehicle energy replenishment anxiety. Therefore, the battery swap connector has attracted attention. The battery swap connector usually includes a plug and a socket, and the socket usually has a small range of free movement, allowing the plug to be smoothly inserted into the socket to achieve connectivity.
[0003] In the related technology, the power exchange connector includes a shell and a cover plate. A spring is provided inside the shell, and the cover plate is arranged on the spring. A plug-in assembly is provided on the cover plate, and the plug-in assembly is used to connect the plug. Since the plug-in assembly needs to move freely, there is a certain gap between the cover plate and the shell.
[0004] The cover plate is set on the spring so that the cover plate can be freely adjusted at an angle when connecting, so as to facilitate the connection between the plug and the connector assembly. Therefore, there is a gap between the cover plate and the shell for the free movement of the cover plate, so that foreign matter can easily enter the shell, causing damage to the spring in the shell, resulting in problems with the connection between the plug and the connector assembly, making the power exchange connector unable to be used for a long time.
