Abstract: A socket (8) for electrically connecting a circuit card (4) to a substrate comprises a dielectric housing (10) defining a card-receiving slot (12) having a bottom surface (24) and a pair of opposite side surfaces (26, 28), and a plurality of contacts (31, 32) spaced apart along the length of the slot. The plurality of contacts include contact beams (37, 38) at least some of which extend to a greater height above the bottom surface than others of the contact beams. Each of the contact beams includes a contact section (45, 46) extending into the slot and having a card-contacting surface (47, 48) for electrically connecting with the circuit card. All of the card-contacting surfaces are at a substantially same height above the bottom surface.

Abstract: A socket for electrically connecting a circuit card to a substrate comprises a dielectric housing (10) having a card receiving slot (12) and a plurality of contacts (30). Each of the contacts (30) comprises an electrically conductive body including a portion rigidly secured with respect to the housing, a lead for engaging a respective circuit trace on the substrate, and an elastic portion extending from the rigidly secured portion along a course which includes first a stress loop (44) and then a contact loop (46). The contact loop (46) is open in a direction toward the slot opening. A pair of opposed contact points (50, 52) at ends of the contact loop 46 extend into the slot (12) through opposite sides thereof for engaging respective contact pads on the circuit card. The stress loop (44) is open in a direction substantially opposite to the contact loop.

Abstract: A socket for establishing electrical connection with a circuit board comprises a dielectric housing having a board receiving slot and a plurality of terminals disposed for engaging respective contacts on the circuit board. The terminals are arranged in at least first and second sets corresponding to respective first and second sets of the contacts on the circuit board. The first set of terminals engages the first set of contacts when the circuit board is inserted into the slot in a first position, and the second set of terminals engages the second set of contacts as the circuit board is pivoted through an angle to a second position. When the circuit board is removed from the socket, the terminals of the second set disengage their respective contacts before the terminals of the first set. Thus, a socket has terminals arranged such that a portion of the terminals provide make first, break last electrical interconnections.

Abstract: A socket for electrically connecting a circuit panel to a substrate comprises an insulative housing (10) defining an elongated slot (12) for receiving the circuit panel (14). A plurality of terminal receiving cavities (16) are spaced apart along a length of the slot, and each of the cavities is open to the slot on opposite sides (22, 24) thereof. The housing includes a rib (20) extending beneath the slot along its length. A plurality of electrically-conductive terminals (30) are disposed in respective ones of the cavities. Each of the terminals comprises an integral body including a housing engaging section (32) having opposed surfaces (34, 36) each gripping a respective opposite side (46, 48) of the rib. Each terminal has a lead (58) extending to an exterior of the housing for electrically engaging a substrate, and a pair of resilient contact arms (52, 62) extending into the slot from respective opposite sides of the slot for electrically engaging opposite sides of the circuit panel.
