Abstract:
An electrical connector for a pin grid array package comprising:a base housing which includes an exterior side facing outwardly from the electrical connector and an interior side forming a generally cylindrically shaped protuberance which extends generally transversely from the interior side, and an internal surface defining a passage which extends axially through the protuberance from the interior side to adjacent the exterior side; a plurality of terminals mounted on the base housing in an array which generally corresponds to the array of the pin grid package; a slide plate which defines a cam opening having an inside surface and through holes corresponding to the terminals, is disposed adjacent the interior side, and is slidably movable between a first insertion position in which a lead pin of said pin grid array package can be inserted via one of the through holes into a location adjacent to, but without engaging, at least one of the terminals and a second engagement position in which the lead pin is engaged with at least one of the terminals; and an eccentric cam member which includes a cam portion which defines a cam surface, a barrel which defines a bearing bore, an engaging leg which extends within and generally along the axis of the bearing bore and projects into the passage from the interior side, and engaging means for engaging the internal surface or the exterior side, said engaging means being mounted on the engaging leg; wherein the cam member projects into the cam opening so that the cam surface is adjacent the inside surface, the protuberance projects into the bearing bore to rotatably support the cam member, the engaging leg projects into the passage, and said engaging means engages the internal surface or the exterior side to resist axial movement of the cam member relative to the bearing bore.
