Abstract: A contact (10) comprising a planar conductor having an elongated base (12) with two opposite spaced ends (14, 16). A pair of contact beams (18, 20) respectively extend from a common position spaced from a first end (14) in a distance of generally one third of the whole length of the base (12). A high beam (18) of such pair of contact beams (18, 20) generally extends upward and slightly inclined to the first end. A generally U-shaped section (22) is positioned at the top of the high beam (18) wherein such U-shaped section (22) is dimensioned to be generally a half of the vertical dimension of the whole high beam (18). A low beam (20) of such pair of contact beams (18, 20) generally extends horizontally to the second end (16) of the base (12). A generally C-shaped section (24) is backward positioned at the free end of the low beam (20) wherein such C-shaped section (24) is dimensioned to be generally a half of the horizontal dimension of the whole low beam (20).

Abstract: A memory card connector assembly has an upper and a lower stacked connectors (10) each including a generally H-shaped housing (12) comprising a main body (14) through which a plurality of contacts (120, 126, 134) extend in the front-to-back direction. Two parallel side guide arms (16, 18) are positioned at two ends of the main body (14) to form a first recess (30) for receiving an alignment comb (140) in the upper connector and an auxiliary socket (150) in the lower connector, and a second recess (38) for receiving a memory card therein. The contacts (134) of the upper connector (10) extend through the alignment comb (140) for horizontal alignment and through the auxiliary socket (150) for vertical alignment. Each connector 10 further comprises a sliding plate (72) operated by a lever (62) for extraction of the inserted memory card. Attached to the housing (12) is a reinforcement plate (100) with tangs (110) for removing electrostatic charge from the inserted card.

Abstract: A chip carrier socket assembly (10) for electrical connecting leads (81) on a chip carrier (80) to a board on which the socket is seated, comprises a base (20) having a chip carrier receiving opening (22) in relation to peripheral walls (24) thereof. A plurality of lower contacts (70) are disposed in the base (20) for electrical connecting to the respective printed circuit board pads.

Abstract: A socket suitable for electrically connecting circuit panels such as single inline memory modules (SIMM) employs a plurality of contacts positioned within cavities in an insulative housing. This socket permits zero force or low force insertion of circuit panels into the socket and is of the type in which the circuit panel is rotated from a first position to a second position where deflection is imparted to the two contact springs. The contact terminals used with this socket are insertable into an insulative housing through the rear of the housing. A cantilever spring extending from the rear of the contact terminal is located on one side of a panel receiving slot and a curved spring is located on the other side of the panel receiving slot.

Abstract: A printed circuit board connector having two parallel rows of posts for receipt in sockets of a printed circuit board includes an elongate post locating member formed on opposite faces with parallel post receiving channels mounted for sliding movement along the posts away from the free ends of the posts during insertion of the posts into the sockets of the printed circuit board. Inadvertent dislodgement of the locating member from the free ends of the posts is prevented by a stop member extending from the locating member engaging an abutment on the connector.
