Abstract
The utility model relates to the technical field of audio connectors, and especially relates to a jack connector preventing connection noise. The connector comprises a main body and a housing sleeved on the main body. An inserting cavity of the main body is provided with a left channel wafer, a right channel wafer, a loop wafer, a detecting moving plate, and a detecting static sheet. The left channel wafer, the right channel wafer, and the loop wafer are respectively provided with connection bulges so as to cooperate to form transmission clamping. The detecting moving plate is provided with a tongue piece so as to cooperate with the detecting static sheet to form trigger clamping. In the inserting cavity of the main body, the trigger clamping is deeper than the transmission clamping so that the trigger clamping is connected later than the transmission clamping. Since the trigger clamping of the jack connector is deeper than the transmission clamping, in a connection process, a plug would arrive at the transmission clamping and then arrive at the trigger clamping, that is, the plug would firstly forms a transmission circuit on a socket and then the plug is triggered to generated a trigger signal, thereby ensuring that the transmission circuit is started after the transmission circuit is effectively connected in audio connection of an electronic device, and preventing noise in the starting process.
