Patent attributes
An audio jack connector has an insulating housing. The insulating housing has a passageway extended from a front surface towards a rear surface thereof for receiving an audio plug connector, a first groove communicated with the passageway and a second groove communicated with the first groove. 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.
