The socket shell has a through hole, a hollow outer casing, a bar, two grooves, two slots, and a recess. A first copper plate is connected to a first main wire. A second copper plate is connected to a second main wire. The hollow outer casing has an inner annular rib and two notches. The socket shell is inserted in the hollow outer casing. The inner annular rib blocks an upper face of the socket shell. The first and the second copper plates are inserted in the grooves to contact the conductive plate. A secondary wire passes through the respective notches and the respective slots.
