Patent ID: 7108529

Claim:
An audio connector comprising an insulated case having an outer end; an inner end; a central socket formed through the insulated case; a first inner recess formed in the insulated case at the inner end, communicating with the central socket and having an inner end; and a second inner recess formed in the insulated case at the inner end, communicating with the central socket and having an inner end; an outer end; and a guide channel formed near the outer end and communicating with the central socket; an inner stationary contact mounted in the first inner recess near the inner end; an first inner resilient contact mounted in the first inner recess and having a distal end making electrical contact with the inner stationary contact; and a protruding contact formed near the distal end, protruding into the central socket and pushed into the first inner recess by and adapted for making electrical contact with a jack when the jack is seated in the central socket; an outer resilient contact mounted in the second inner recess and having a distal end protruding into the central socket to be pushed into the second inner recess by and to make electrical contact with the jack when the jack is seated in the central socket; a resilient switch contact mounted in the second inner recess and having a distal end corresponding to and aligning with the guide channel; a second stationary switch contact mounted in the second inner recess between the outer resilient contact and the resilient switch contact to make contact with the resilient switch contact when the jack is seated in the central socket; and a slide mounted movably in the guide channel, pressed toward the central socket by the resilient switch contact, extending into the central socket and adapted for pressing the distal end of the resilient switch contact to disconnect the resilient switch contact from the stationary switch contact when the jack is seated in the central socket, wherein the slide has a circular head selectively extending into the central socket.
