Patent ID: 7568929

Claim:
An audio jack connector adapted for mating with a plug connector which has an insulating loop thereon, comprising: A dielectric housing defining an inserting hole therethrough; a plurality of signal terminals received in the dielectric housing; and a set of switch terminals having a first switch terminal and a second switch terminal disposed in the dielectric housing, the first switch terminal having a first fixing portion fixed in the dielectric housing and a first elastic contact arm, the second switch terminal having a contact portion extending into the inserting hole, the second switch terminal having a second fixing portion fixed in the dielectric housing, and a second elastic contact arm extending slantwise from one side of the second fixing portion, the second elastic contact arm being separated from the first elastic contact arm when the plug connector is not inserted into the dielectric housing; wherein, when the plug connector is fully inserted into the inserting hole, the signal terminals are electrically connected with the plug connector, the contact portion of the second switch terminal is against and pushed outwardly by the insulating loop of the plug connector to make the second switch terminal electrically connected with the first switch terminal.
