Abstract: The invention disclosed herein relates to a test socket for making solderless connections between an electrical component and a printed circuit board. The socket includes a lid member that translates longitudinally with respect to a base member upon operating a cammed actuator. The lid member is connected to and guided upon the base member by a plurality of flexible linking clips. The invention includes a plurality of electrical connectors having a pair of resilient beams that are preloaded. A lead portion is formed from one of the opposed beams and extends unitarily therefrom.

Abstract: Crimp-on connectors and housing are provided for a flat cable. The connectors may define either sockets or plugs. Each connector includes a cable mounting end affixed to a carrier strip. The cable mounting end has barbs for piercing the cable and a lance for aligning the cable. A contact end of each connector enables secure mounting of the connector in the housing. The housing is adapted to receive either a socket or plug connector.

Abstract: An ejector socket for DIP jumpers is provided which includes a socket member and a pair of opposed latches. Each latch is pivotably mounted between a pair of locking arms which are disposed on opposed ends of the socket member. The locking arms cooperate with the respective latches to enable the latches to be lockingly retained in a position where the latches will securely maintain the DIP jumper in the subject ejector socket. The latches can be rotated out of their locked positions, thereby urging the DIP jumper out of the subject ejector socket. The socket member preferably is formed from a unitary piece of plastic.

Abstract: An IC pin adjustment tool includes a pair of side arms and a center portion disposed between the side arms. The side arms are hingedly mounted on the center portion at one end thereof, and biased outwardly away from the center portion by spring means attached to the other end of the side arms. The center portion, and the portions of the side arms adjacent to the center portion, are configured such that an IC of either of two widths may be disposed on the associated one of two sides of the center portion such that the IC pins extend into gaps between the side arms and the center portion. By squeezing the side arms toward each other, the side arms force the pins toward the center portion to thereby adjust the orientation of the pins, such that they may immediately be inserted into an IC socket without further adjustment.

Abstract: A connector is disclosed for electrically interconnecting the conductive pins of an electrical component to a printed circuit board. The connector includes a plurality of conductive contacts mounted within a non-conductive housing. Each contact includes first and second upwardly extending arms spaced apart a distance sufficient to permit a conductive pin of the electical component to be freely mounted therebetween. The first arm of the contact is generally V-shaped in configuration and defines an intermediate projecting section, extending away from the second arm. A cammed closure is provided for exerting a force on the projecting section of the first arm in a direction towards the second arm. By this arrangement, after a conductive pin is mounted between the arms of the contact, the actuation of the cam causes the first arm of the contact to be moved into electrical contact with the conductive pin of the component.

Abstract: A plurality of flat conductor cable connector assemblies according to the subject invention may be aligned in an abutting planar array such that the contacts of adjacent connector assemblies are spaced at 0.100 inch intervals corresponding to the 0.100 inch spacing between the individual contacts of each flat conductor cable connector assembly. Each of the latter includes a flat conductor cable having a plurality of uniformly spaced electrical conductors connected to the contacts which are disposed within the housing portion of a planar insulator block. The flat conductor cable is tapered adjacent said contacts, with the tapered width of the flat conductor cable corresponding to the tapered dimension of a tongue portion of the planar insulator block.

Abstract: An electrical connector for terminating a flat conductor cable includes inherent strain relief means, and is constructed to facilitate interconnection of the conductors of the flat conductor cable to the terminal pins of the connector. The latter includes a plastic carrier having a central bar member which receives a parallel array of terminal pins, and formed unitary with the bar member are two planar cable support members. The latter are hingedly connected to the bar member such that they may be initially pivoted to a folded position to facilitate soldering of the terminal pins to the conductors of the flat conductor cable. Next, the planar support members may be pivoted about their hinge connections so as to engage the opposite surfaces of the flat conductor cable, where the planar support members are secured together.

Abstract: A socket for vertically mounting a light emitting diode relative to a generally horizontal printed circuit board includes an elongated housing for receiving the LED, and a triangular housing connected to the elongated housing. Aligned apertures extend through the elongated housing and the triangular housing, and a corresponding plurality of terminals are disposed in the aligned channels. The receptacle portion of each terminal is disposed in the elongated housing for engaging a pin of the LED, while the post portion extends through the channel and out of a side edge of the triangular housing, whereby the axes of the terminal post portions of the terminals are at an angle to the axes of the terminal receptacle portions. Since the terminals are wholly disposed within the socket, except for the terminal post portions, the terminals may be formed of a thin, stamped electrically conductive material.

Abstract: In a method for making a flexible electrical jumper, an elongated flat strip of electrically conductive material is die-cut to form a plurality of electrical leads interconnected by a carrier strip which extends along the longitudinal axis of the strip of conductive material. Each lead includes a central, flexible flat portion, and opposed contoured ends which are formed into generally U-shaped cross-sections. Sheets of insulative plastic material are laminated to the opposite sides of the central flat portion of the strip to embed the leads therein, with the contoured ends being exposed. The carrier strip is removed and the insulating material is cut at the desired locations, depending on the number of leads required for the flexible jumper. The method of the invention is carried out in a continuous operation, and the resulting flexible jumper is characterized by the exposed termination ends which are rigid and have generally arcuate, U-shaped cross-sections.

Abstract: A low profile socket for receiving an electronic multi-pin package is characterized by having a housing including a plurality of elongated channels, and a corresponding plurality of terminal pins. Each terminal pin includes a receptable portion that is disposed within a channel in the housing, and furthermore includes a post portion which extends from one side of the housing. Each channel includes a flexible membrane portion having an aperture through which the post of the terminal pin extends, with the aperture of the flexible membrane portion being smaller in cross-section than the cross-section of the post. Accordingly, when the terminal pin is fully inserted in the housing, the flexible membrane portion is flexed or stretched, and thereby forms a fluid type seal with the terminal post, thereby restricing liquid or foam flux and solder from entering the channel of the socket when the socket is being connected, such as by wave soldering, to the associated printed circuit board.
