A socket connector includes an insulating housing, at least one terminal set and a switch module. The insulating housing defines an inserting hole. The terminal set and the switch module are respectively received in the insulating housing. The switch module includes a fixed terminal, a movable terminal and an insulating guider. The insulating guider is connected to the moveable terminal and electronically insulated from the moveable terminal for preventing signal transmitted by the socket connector from influence. Because the movable terminal is molded with the insulating guider, the strength of the switch module of the audio socket connector will be improved. Since, the audio socket connector has strong structure and high reliability.
