A first switch terminal received in the first groove has a base plate, an elastic arm extended from one end of the base plate and bent towards the passageway, and a first contacting portion formed at a free end of the elastic arm. A first convexity is formed at a substantially root portion of the elastic arm. A second switch terminal received in the second groove has a second contacting portion. The first contacting portion is driven to move outwards to contact with the second contacting portion when the audio plug connector is inserted in the passageway and resists against the first convexity outwards.

A connecting slot is opened in and penetrates through a rear wall of the receiving chamber. A rear edge of the base board is provided with a contact slice passing through the connecting slot and then bent against the rear wall. A rear edge of the base plate is bent downward and then arched forward to form a contact tail which is located behind the rear wall and electrically abuts against the contact slice to achieve a ground function of the inner shell.

At least one end of the base board extends downward to form a connecting portion defining a second fixing structure thereon which can be buckled with the first fixing structure.

Abstract: An audio jack connector includes a dielectric housing and a plurality of contacts received in the dielectric housing. The dielectric housing defines an insertion hole therein for an audio plug inserted into. One of the contacts is located at a rear of the dielectric housing and includes a bottom plate, a first fixed plate and a second fixed plate respectively extended upward from two opposite ends of the bottom plate. A contact protuberance is protruded towards the second fixed plate from a portion of the first fixed plate. A flexible plate is extended from the second fixed plate to be located between the first and second fixed plates. The flexible plate defines a contact convex protruded towards the first fixed plate at a free end thereof. The contact protuberance and the contact convex are both projected into the insertion hole for contacting with the audio plug.
