  • Patent number: 4260209
    Abstract: An improved transmission cable connector is disclosed for providing mass termination of pre-stripped flat transmission cable having conductors on closely spaced centers with the connector providing selective programming of grounds within the connector. The connector includes three sub-assemblies, namely, a cover, a housing assembly with a plurality of receptacle type contacts and a ground bus mounted therein, and a strain relief member. The present connector employs slotted beams to effect a connection between the conductors and grounds of the cable and the terminals and bus bars of the connector. The cable is prepared in a cable stripper to cut the insulation and displace it towards the free end of the cable sufficiently to allow the conductors to be seated in the connector cover. The application tooling then inserts the exposed conductors into the proper alignment slots of the cover while simultaneously trimming them to the correct length.

  • Patent number: 4257658
    Abstract: A cable shield connector assembly for making electrical connections to the shield of a multi-conductor communications-type cable includes a split cylindrical sleeve having circumferentially spaced contact ridges for insertion about the conductors and within the shield and further includes clamp halves positioned about the sleeve with a portion of the shield and the external insulation sheath of the cable therebetween. The clamp halves are drawn together by screws to urge the shield into electrical contact with the ridges of the sleeve. The sleeve includes a tab projecting through a slit in the shield and sheath to receive a screw for connection of a ground conductor thereto. The tab preferably extends between a portion of the clamp and receives one of the clamping screws therethrough to thereby locate and fix the clamp halves around the sleeve.

  • Patent number: 4255006
    Abstract: A strain-relief member is provided to relieve torsional strains from a two-conductor power supply cord attached to a personal care electrical appliance, such as a hand-held hair dryer, or curling iron. It is molded to the insulation of the two-conductor electrical power supply cord. Such torsional strains are primarily those resulting from twisting the wire about its longitudinal axis, as when using a curling iron, rather than from flexing.The strain-relief member is an elongated body member of elastomeric material molded with the usual two-conductor line cord. It has a lateral projection or collar on one end thereof adapted to fit into the interior of the personal care electrical appliance to prevent rotation with respect to the appliance. The outer portion of the body member is uniformly tapered along its length on the sides adjacent to single conductors of said cord and has flattened, generally parallel sides extending along the opposite sides which are adjacent to both conductors of the power supply cord.

  • Patent number: 4248490
    Abstract: A lay-in lug which may be used for a grounding connection by securing it to a conductive bushing, or the like, is disclosed. The lug comprises a body member for providing strength and rigidity and a conducting member, supported by the body member, for providing a low resistance conduction path. The conducting member is in direct contact with both the laid-in wire and the bushing, or the like, whereby a low resistance conduction path is provided between the wire and the bushing. First and second clamping means secure the lug to the bushing and hold the wire in contact with the conducting means, respectively. The conducting member may be selectively removable from the body member and may include a turned-up lip for helping to retain a wire in contact therewith. The conducting member may also include means for inducing slight deformation of a wire compressed thereagainst to increase the pull-out force required to extract the wire.

  • Patent number: 4245874
    Abstract: A flexible connector assembly for coupling, both mechanically and electrically, sections of electrical distribution track in a track lighting system includes first and second connector segments each having at a first end, a plug-in type tapping mechanism for joining the segments mechanically and electrically to sections of electrical distribution track. A flexible and expandible member formed of a pair of conductive, coiled, wire elements concentrically wrapped in opposite directions with respect to each other, is joined at opposite ends at the second ends, respectively, of the connector segments. The coiled wire elements define a tubular passageway for electrical conductors coupling the connector segments electrically and the member itself provides a ground connection between the connector segments and corresponding track sections.

  • Patent number: 4232928
    Abstract: Apparatus having special utility for the electrical interfacing of multi-terminal circuit testing equipment to multi-contact printed circuit boards or the like employs a fluid pressure responsive, resiliently flexible diaphragm for controllably effecting concurrent, individual, substantially equal force engagements between shiftable, rigid contacting elements and corresponding stationary contact points on the unit to be tested, despite possible lack of precise co-planarity of such contact points. The arrangement is space conserving and permits the elimination of expensive and troublesome spring contact pins, the utilization of desirable wirewrap connection techniques in fabricating interfacing assemblies, and the convenient disposition of all points of electrical contact with both the testing equipment and the unit under test at one side of the interfacing assembly.

  • Patent number: 4227760
    Abstract: A lamp socket adapted to receive a bayonet base lamp bulb for illumination uses on an automotive vehicle. The socket is essentially cup-shaped and of one-piece plastic construction. The bulb contacting terminal members and grounding ring are all adapted to be inserted from the bulb end of the socket. The terminal members snap into designated slots in the bulb receiving wall of the socket. The grounding ring is a unitary, formed member with terminals at both opposed ends. The grounding ring forms the wall into which the bulb base is inserted. With the terminal members and grounding ring in place, terminals are provided for the engagement with conductors of a printed circuit board. The terminals have spring contactors spaced in an annulus insulated and spaced from the bulb. The bulb imposes a locking pressure on the bulb terminals by pushing the terminals further into the assembly.
