Patent ID: 7112099

Claim:
An audio jack connector, disposed in a communication device and electrically connected to a printed circuit board for electrical connection with a mating audio connector, comprising: an insulative housing having a mating face and side edges, the mating face joined to two opposed top and bottom faces, the insulative housing defining slots with openings of the slots located in the bottom face and extending to the top face, the mating face defining an aperture opening to a connector receiving channel communicating with the slots; a plurality of terminals disposed in the slots and insertable from the openings of the slots located in the bottom face, each terminal having a base portion, a resilient arm extending from one end of the base portion and bent reversely toward the top face, a free end of the resilient arm forming a hemispherical contact portion designed to engage conductors on the mating audio connector when inserted in the connector receiving channel, and a soldering portion extending from another end of the base portion designed to be soldered to the printed circuit board, the slots being oriented at two opposite sides of the connector insertion channel; one of the slots being located near one of the side edges of the housing and another of the slots being located between the side edges of the housing; the inner surfaces of the slots in the insulative housing including an internal wall face, the internal wall face joined to two opposed side wall faces, the side wall faces forming two symmetric projecting bars which define symmetric grooves formed between the two projecting bars and the internal wall face, where side edges of the base portion of the terminals forming interfering tabs which mechanically engage the two symmetric grooves; the contact portion of the terminal further including a projecting face, the-projecting face being located at one side of a central axis of the connector insertion channel of the insulative housing, and the mating audio connector is inserted into the connector insertion channel and electrically engages the projecting face; and the insulative housing further including a slit and one switch terminal received in the slit, an end of the switch terminal electrically engaging the free end of the resilient arm of the terminal and designed to disengage from the free end when a mating audio connector is inserted through the aperture into the connector receiving channel.
