Abstract: An inherently resilient metallic latch structure is provided for use in connection with a socket structure for a memory module board. The latch structure is separately manufacturable from the socket structure, and is applied thereto in a separate operation, and is effective to retain the memory module board against inadvertent release from the socket. For intentional release of the memory module from the socket, the latch requires only a downwardly directed force to be applied to a latch lever forming an integral part of the latch to impose a bending moment on the latch, effectively releasing the memory module board from the socket and permitting resilient ejection of the board from the socket. In a second aspect, the latch is integrally formed with the socket body, but includes an integral latch lever that may be depressed by application of a downwardly directed force to impose a bending moment on the latch to release the memory module board from the socket.

Abstract: A contact for circuit board socket includes a planar conductor having an elongated base with oppositely spaced ends. A fulcrum leg is formed on one end of the base and has a cut-out space extending from outermost edge to the inside middle portion of the base so as to make the fulcrum leg more flexible. A contact leg is formed on the other end of the base and has a cut-out space extending lengthwise thereof between first and second parallel and spaced apart planar beam sections. The end of the base sections remote from the base are joined and the cut-out space extends to the middle portion of the base but does not communicate with that of the fulcrum leg. The conductor furthermore provides a stop means at the side of the contact leg, which cooperates with a similar stop means at the outer portion of the fulcrum leg to form a pair of stop means.

Abstract: A one-piece boardlock formed from an elongated metallic strip comprises a vertical mounting portion, and an integral horizontal portion extending from one end of the vertical portion. At the end of the horizontal portion remote from the vertical portion a pair of side legs are formed from two laterally spaced side portions by three successive right-angle bends so that the side legs project perpendicularly from the strip. Similarly, a pair of auxiliary legs are formed from an intermediate portion of the horizontal strip portion by stamping and bending. These four legs are positioned symmetrically around a central axis perpendicular to the horizontal strip portion. An outwardly inclined cam surface is provided adjacent each leg end, and an inwardly inclined cam surface is positioned intermediate the outwardly inclined cam surface and each leg end.
