  • Patent number: 6296533
    Abstract: An electrical receptacle contact is provided having contact beams which are asymmetrically opposed, defining a terminal receiving section therebetween. Asymmetrically opposed contact beams may have various widths to provide an appropriate spring force for a selected plating material, while ensuring that the receptacle contact maintains the same overall dimensional shape as contacts made with a different plating material. Although allowing for variable spring rate in limited dimensioned contact, susceptibility of fracture of the contact of the present invention during forming is minimized.

  • Patent number: 5931688
    Abstract: An electrical connector assembly for mounting an electrical component, such as a radio, on a panel. The connector assembly permits blind mating of a radio in a dash. A header on the radio is mated to a plug connector on a wiring harness. The plug connector is mounted on a mounting member on a panel. When the component is inserted through an opening, such as an opening in an automobile dash, the plug connector can shift into alignment with a header on the component. Ramps on the header and on the plug connector cam the mating connectors into alignment permitting movement in a plane perpendicular to the mating direction. Alignment and movement in the mating direction is permitted by springs holding the plug connector on the housing. Metal springs exerting a mating force when deflected can be use. Alternatively molded cantilever latches can be deflected. The mated connectors can still move in the axial direction after mating.

  • Patent number: 5897404
    Abstract: The invention comprises an electrical contact having a body with a crimping section and a base with resilient contact fingers extending forwardly from the base. The base has a tapered cylindrical section. A sleeve is secured over the base and the resilient contact fingers. The sleeve engages the tapered cylindrical section in an interference fit to secure the sleeve thereon.

  • Patent number: 5782657
    Abstract: A plug housing assembly (10) with an outer socket (20), and inner socket (30), a primary latching member (40), a secondary lock member (60) and electrical contact assemblies (80). The inner socket (30) includes contact receiving apertures (34) for receiving latching beams (44) of the primary latching member. The secondary lock member (60) is inserted transversely relative to the contact insertion direction into inner socket (30) so that walls (65a) of contact chamber (65) will engage a sleeve (82) of electrical contact assembly (80), and bottom wall (66a) of latch chamber (66) of secondary lock member (60) will be disposed adjacent to latching beams (44) so that the beams (44) are secondarily locked into place.
