Patent ID: 7210970

Claim:
An electrical socket for a housing mounting a circuit comprising a first wall member of the housing having a face surface formed with an open connector pin receiving channel in the face surface extending along a selected axis, the channel defined by a channel surface having a first axial length of a selected first depth extending from an outer end to an inner end along the selected axis, a shoulder formed by a surface at the inner end extending from the channel surface at the first depth toward a second depth at the inner end, an electrically conductive spring member disposed over the channel, the spring member extending over the first axial length aligned with the channel to electrically engage a connector pin inserted into the pin receiving channel and urge the connector pin against the channel surface, whereby a connector pin having a size to be accommodated in the channel and having a shoulder formed by a radially extending flange that is inserted into the outer end of the channel will be biased by the spring member against the channel surface of the first axial length and upon further insertion when the flange moves beyond the inner end of the first axial length and being biased by the spring member, a portion of the flange will move between the first and second depths with the flange engaging the shoulder at the inner end serving as a stop surface inhibiting extraction of the connector pin.
