Abstract: A first aspect of the invention is an electrical connector that includes a housing formed to include first and second opposing ends and an elongated slot between the ends. The slot receives a connective edge of a printed circuit card. Closely spaced contacts located in the slot engage conductive pads on the printed circuit card. A first alignment member is formed integrally at the first end of the housing, to engage a non-polarized keyway during insertion of the printed circuit card into the elongated slot, aligning the printed circuit card relative to the contacts. A second aspect of the invention is the keying of the printed circuit card along a connective edge. The connective edge includes two connective regions which define a polarized keyway between the two connective regions. A third, non-connective, region located at one end of the connective regions defines a non-polarized keyway between the connective regions and the non-connective region.

Abstract: An electronic assembly that incorporates a heat sink. The subassembly includes an integrated circuit package that is mounted to a substrate. The substrate is mounted to a spacer block which includes a pin field that contains a plurality of pins. The heat sink is coupled to the integrated circuit package by a clip that wraps around the sink and is attached to the spacer block.

Abstract: An apparatus for retaining a circuit board in a connected position is constituted with a top cover and a U-shaped retention body. The top cover has pivoting features disposed at one end and locking features disposed at the other end. The U-shaped retention body has a base and a cavity disposed therein, and two arms rising from each side end. The rising arms include receiving features correspondingly disposed on their top ends. The top cover pivoting features mate with one the receiving features to allow the top cover to pivot at one of the top ends, placing the apparatus in an open position for inserting the circuit board into the cavity, and in a closed position, with the locking features mating with the other receiving feature, securing the inserted circuit board.
