Abstract: A socket for dual in line package integrated circuits has a high retention force for a correspondingly low insertion force. Each of a plurality of contacts in a dielectric housing bends relatively easily as a lead of such package is inserted and as such insertion is completed the contact assumes a residual position for good electrical and mechanical connection to the lead. Friction between the lead and contact effects movement of the latter to change the geometry thereof as the former is withdrawn, whereby the contact binding force against lead increases to increase the force required for completion of such withdrawal.

The connective means includes a base member having a projecting hollow-stack portion which is formed to protectively encompass the sealed tubulation. Additionally, the hollow-stack has a metallic contact recessed therein, ahead of the seal, to which the protruding seal-related lead is affixed. A central recess is formed in a mating socket member to match the projecting stack of the base member. The stack is telescopically positioned within the recess to enable a receptor contact located therein to make seated abutment with the metallic contact in the base.

Abstract: An electrical connector in which two rows of resilient contacts are mounted in a connector housing which is adapted to receive therein conductors on an electrical component that are desired to be engaged by the contacts. The contacts have spring contacting portions which extend resiliently toward a center wall in the housing. Means is provided for retracting the contacts away from the center wall so that the conductors on the electrical component may be inserted into the connector housing with zero insertion force. Such retracting means includes laterally extending fingers pivotally connected to the center wall. The contacting portions of the contacts extend through vertical openings in the fingers. A cam actuator underlies the ends of the fingers. Longitudinal movement of the cam actuator raises the fingers, whereby the contacts are cammed outwardly away from the center wall in the housing.

Abstract: A plurality of elongated bridging contacts each extending in a first direction are mounted on a pair of support blocks that are driven in a symmetrical, reciprocating motion between first and second limit positions. In the first position each contact makes electrical connection at one end with a lead of a semiconductor device to be tested and at the other end with a contact pin that is connected directly to a load board. The contacts are preferably pivotable to a limited degree about a point intermediate the contacting ends and flex slightly when in the first position to develop a good contact force. In the second position the contacts are spaced from the leads and the pins. Driving means for the support blocks, as well as the support blocks themselves, are structured to provide a minimum separation along the first direction between the load board and the device (preferably less than 25 millimeters) and an unrestricted mating plane for the load board.

Abstract: A connector assembly for a coaxial cable having an annularly corrugated outer conductor has a first unitary clamping member which fits over the end of the coaxial cable and forms an inwardly extending bead at one end thereof for meshing with the last valley in the corrugated outer conductor, thereby locking the clamping member to the cable in the axial direction. One side of the bead also forms a first conically beveled clamping surface for engaging the outer surface of the last crest in the corrugated outer conductor. When the clamping member is advanced over the cable during installation of the connector assembly, the bead cams a plurality of resilient segments in the beaded end of the clamping member outwardly to clear the crest of the corrugated outer conductor.

Abstract: A replacement cover plate for a conventional wall outlet is disclosed, the cover plate being modified to include pivoted release plates disposed over each plug receptacle. Each release plate is conformed to the plan form of the receptacle itself and includes in the face thereof the necessary openings for receiving the terminals of a plug. Formed on the wall plate, adjacent to one edge of each receptacle are two opposed tabs adapted to receive a cylindrical fulcrum extending from the adjacent surface of the corresponding release plate. Extending from each release plate, distal of the fulcrum, is a cantelevered, raised projection or lever which when manually depressed will pivot the release plate away from the adjacent receptacle. Thus a plug inserted through the openings in the release plate and received in the receptacle will be withdrawn out of the receptacle by the articulation of the release plate.
