Abstract: A high-voltage energy storage quick connector including a socket and a plug. The socket includes a hanging platform with a convex ring located on the outer circumference of the socket. An annular slot is defined on the plug. The socket and the hanging platform are inserted in the annular slot of the plug. The plug includes an elastic hook configured in a cantilever structure on the side wall of the annular slot. The cantilever structure of the elastic hook extends axially along the plug in a free state. A hook of the elastic hook is engaged with a stepped surface of the hanging platform facing away from the plug. The plug includes an operating handle disposed along an elastic deformation direction of the elastic hook, and the operating handle is connected to the plug in a locking manner along the elastic deformation direction of the elastic hook.
