A waterproof pad is provided at the end of the plug housing. The socket includes a socket housing, a hole insulator, a 350A socket, and a second shock-absorbing pad. The 350A socket is disposed within the hole insulator, and the hole insulator is fixed inside the socket housing by the second shock-absorbing pad. The plug and socket have pre-threaded outlets to match cable connectors or hose connectors.
