Electrical connectors having dual biased contact pins

Abstract

An electrical coupling system includes a printed circuit board (PCB) that is selectively fixed to an electrical apparatus. The PCB has an elongated finger with a plurality of partially exposed contact lines formed thereon. A jack includes a slide plate having an aperture extending therethrough and a channel communicating with the aperture. The aperture is configured to receive a media plug. Mounted on the slide plate so as to be positioned over the channel is a pin block. The pin block has a plurality of elongated slots formed therein. The slots face the channel and are separated by insulating walls. Disposed within each of the elongated slots is a substantially S-shaped pin. Each pin has a tail end that is mounted to the pin block, a downwardly curved portion that extends within the channel, and an opposing lead end which is freely disposed within the aperture of the slide plate. The finger of the PCB is slidably received within the channel of the slide plate such that the jack can be selectively moved between an extended position and a retracted position. In the extended position the aperture is openly exposed to receive the media plug and the downwardly curved portion of each pin is biased against the exposed portion of a corresponding contact line on the PCB.
