The socket module and the PCB control module are placed in the shell as an integral module, which is easy to assemble and does not occupy too much space in the shell, ensuring the integration of components inside the shell and the miniaturization of the socket. In addition, the L-pole connection socket and the N-pole connection socket on the socket module are evenly distributed on both sides of the entire socket module and are connected to other pole pieces by plugging, which reduces the number of welding times, makes assembly efficiency simpler and faster, and effectively reduces production costs.
