Abstract
A low profile socket connector includes a plastic, rectangular, frame-like base member (11) having substantially rigid walls (21,22,23,24) defining between them a socket (20), receiving an LGA device (16) in coplanar relation. Beam springs (34,35), integrally formed with two adjacent walls (22,24) adjacent one corner, protrude into the socket (20) into biassing engagement with adjacent edge portions of the LGA device (16) forcing opposite adjacent edge portions into abutment with walls (23,25) defining the opposite corner, automatically locating and maintaining the device (16) in a reference position (A). A stud-like, outer securing member (14) with flexible legs (48) is insertable in a mounting socket (38) in the base member (11) and through an aperture in a circuit board (18) and an inner securing member (15) is completely receivable in an axial passageway (43) in the outer securing member (14) to spread the legs (48) into anchoring engagement with the circuit board (18). Recesses (27,28) with retaining pins (31,32) on a lower face of the base member (11) enable secure preassembly of an elastomer connector (13) on the base member (11) prior to application to the circuit board (18).
