Patent ID: 7922542

Claim:
An audio jack connector for receiving an audio plug, comprising: a dielectric housing, the dielectric housing defining an insertion hole extended along a front and rear direction for receiving the audio plug from a front thereof and a receiving trough at a rear portion of a top surface thereof, an opening being defined at a middle of the receiving trough, a notch being communicated with a rear end of the opening and transversely penetrating through a side of the dielectric housing, a location slot being defined at the side of the dielectric housing to intersect the notch; a detection terminal having a fixed base inserted into the location slot and an inclined portion inclined towards the notch from a top of the fixed base, the inclined portion having a protuberance provided on an outer surface thereof; and a signal terminal received in the receiving trough, the signal terminal having a base plate and an elastic arm extended rearward from a middle of a rear edge of the base plate, the elastic arm having a concaved portion formed at a rear end thereof to project into the insertion hole from the opening and a cantilever arm transversely connected to a rear of the concaved portion by an inner end thereof to be located to the notch, a free end of the cantilever arm being inclined downward to form a pressing portion for pressing against or detaching from the protuberance of the detection terminal when the audio plug is drawn out or inserted into the insertion hole of the dielectric housing; wherein two opposite sides of the receiving trough respectively define a fixing hole at the same side of the location slot and an L-shaped groove opposite to the fixing hole, the L-shaped groove includes a long groove longitudinally extended and a short groove transversely extended towards the notch from a rear end of the long groove.
