Abstract: An electrical connector housing comprises a housing member (20) of dielectric material having passageways (22, 24) extending therethrough in which electrical terminals (50, 60) are disposed. Integral flap members (10, 10') are hingedly located adjacent a back end of the housing member (20) and they include projections, (11, 12') for engaging and maintaining the terminals (50, 60) in the respective passageways (22, 24) when the flap members (10, 10') are in their latched closed positions. Hook members (13) are located on the flap member (10) adjacent the projections (11) and they include hooks (14) that engage inner surfaces of the passageways (22) to prevent the flap member (10) from deflecting outwardly when forces are applied to the terminals (50) that are opposite to the direction of insertion of the terminals (50) in the passageways (22).

Abstract: An electrical connector for use in electrically connecting a pair of cables. More particularly the connector includes a tapered, C-shaped member and a wedge member for being driven into the C-shaped member to secure the cables therein. According to one embodiment, bolts, cooperating with a flange crossing an end of the wedge member, are threadedly advanced into apertures on the C-shaped member to drive the wedge member. In a second embodiment, a bolt, mounted on the C-shaped member is threaded into a sleeve on the wedge member to pull it into the C-shaped member.

Abstract: Contact pin has a compliant portion having two spaced-apart openings therein at locations adjacent to the ends of the compliant portion. The compliant portion is sheared along a shear line extending axially between the openings. The shear line divides the compliant portion into two side-by-side beams. The beams are displaced in opposite first directions away from the axis of the pins. The openings and the shear line define ears on each beam which extend towards the other beam. When the compliant portion is inserted into a circuit board hole, the ears are moved into overlapping relationship and the compliant portions are flexed in second opposite directions which are normal to the first opposite directions. The ears of each beam function as an intermediate support for the other beam. A high degree of adaptability as regards stock thickness and dimensions of the pin is achieved by virtue of the fact that the beams are flexed parallel to their major surfaces and are supported intermediate their ends by the ears.

Abstract: A reference conductor for improving signal integrity in connectors and connector systems. More particularly the reference conductor includes a conductive plate positioned between adjacent rows of signal conductors in a connector and which is electrically connected to reference circuits on substrates associated with the connector to provide a low inductance signal return path.

Abstract: The disclosure relates to a retainer for locking a printed circuit board into an edge connector having side ears with an aperture through each ear. The retainer includes two pairs of legs extending from a body in a first direction with flanges on the distal portion of each leg. The inner pairs of legs extend through the aperture in each of the ears with the flanges extending back over the ears. The outer legs extend around the ears with the flanges extending back over the ears to secure the retainer to the ears. The retainer includes a third pair of legs which extends outwardly from the body in a direction opposite to the above mentioned pairs of legs, one of these legs having a laterally extending pin and the other of these legs having an aperture for lockingly receiving the pin therein. The pin is disposed through an aperture in a circuit board to lock the board in the connector.

Abstract: An electrical terminal having an insulating sleeve thereon. More particularly, the terminal includes a copper ferrule located on the wire barrel of the terminal and an insulating sleeve over the ferrule. The sleeve is secured to the terminal by an end thereof being clinched between a bell-mouth end of the ferrule and the wire barrel.

More particularly, the connector includes a C-member defining cable-receiving channels and having an arcuate portion in the web section extending between the channels to define an interior space in communication with an offset from the channels. Also included is a tapered drive member which is advanced into the space to engage the cables positioned in the channels to secure and electrically interconnect them.

Abstract: Electrical cable assemblies formed by joining two halves or sections with each section having grooves extending from end to end and outwardly projecting ribs alongside the grooves with the grooves and ribs on one section being laterally shifted relative to the other section so that when the sections are brought together, the ribs enter facing grooves on the opposing sections to cooperatively form passageways for electrical contacts positioned in the grooves. A fixture useful in assemblying the electrical members and a method are also disclosed.

Abstract: An electroplating cell includes a chamber which defines at least one elongated slot. The chamber is fixedly mounted in place such that the slot extends along a translation axis, along which parts to be plated are moved. An elongated brush is fixedly mounted in the chamber to pass through the slot in order to wick plating solution from the chamber, through the slot, into contact with the parts to be plated. The slot and the brush preferably define a large aspect ratio in order to provide high precision plating of small selected surfaces in combination with high plating rates. Preferably, the brush includes a dielectric strip, an anode strip, and a fabric sleeve which is stitched to the dielectric strip to hold the anode strip in place.
