• front metal contact pieces and a rear metal contact mounted inside the insulated shell;
• front fixation seats for fixing the front metal contact pieces and a rear fixation seat for fixing the rear metal contact piece are provided inside the insulated shell;
• the front metal contact pieces and the rear metal contact piece are electrically connected by being welded onto a circuit board;
• front wire insertion openings corresponding to the front fixation seats and the front metal contact pieces are provided on a front portion of the insulated shell;
• a rear wire insertion opening corresponding to the rear fixation seat and the rear metal contact piece is provided on a rear portion of the insulated shell;
• a top portion of the insulated shell is provided with front press buttons through the insulated shell and corresponding to the front metal contact pieces, and a rear press button through the insulated shell and corresponding to the rear metal contact piece;
• coordination between the front press buttons and the front metal contact pieces and between the rear press button and the rear metal contact piece allows wire connection and disconnection with the front metal contact pieces and the rear metal contact piece respectively;
• there are at least two front metal contact pieces and one rear metal contact piece;
• wherein each of the front metal contact pieces has two front wire connection metal blocks adjacent and connected with each other;
• each of the front wire connection metal blocks comprises a hollow front rectangular frame, a front resilient metal strip having one end formed at a bottom side of one end of the front rectangular frame and another end curled upward in a C shape so as to insert into the front rectangular frame and abut against an inner top side of the front rectangular frame, a long pin and a short pin integrated integrally with the front rectangular frame as a one whole piece and provided at an upper part and a lower part of another end of the front rectangular frame respectively, and a front hole positioned on a top part of the front wire connection metal block to allow a press end of a respective front press button to pass through to press against the front resilient metal strip;
• front insertion holes corresponding to the short pin and the long pin of each of the front wire connection metal blocks are provided on the circuit board;
• the rear metal contact piece has two rear wire connection metal blocks adjacent and connected to each other;
• each of the rear wire connection metal blocks comprises a hollow rear rectangular frame, a rear resilient metal strip having one end formed at a bottom side of one end of the rear rectangular frame and another end curled upward in a C shape so as to insert into the rear rectangular frame and abut against an inner top side of the rear rectangular frame, two rear pins provided at an upper part and a middle part of another end of the rear rectangular frame respectively and integrated integrally with the rear rectangular frame as a one whole piece, and a rear hole positioned on a top part of the rear wire connection metal block to allow a press end of the rear press button to pass through to press against the rear resilient metal strip;
• rear insertion holes corresponding to the rear pins are provided on the circuit board;
• the two rear pins of the rear rectangular frame are provided at different sides of said another end of the rear rectangular frame.
