  • Patent number: 6264496
    Abstract: An electrical receptacle for electrical connection to insulated electrical conductors comprises a dielectric housing (12) including a first housing section (22) and a second housing section (24); first and second electrical contact members (38, 40) disposed in the dielectric housing (12) and having first contacts (38b, 40b) in alignment with slots (26, 28) of the dielectric housing and second contacts (38a, 40a) in alignment with openings (58) of the dielectric housing including insulation-displacement contacts; and conductor-moving members (16, 18) associated with the insulation-displacement contacts-for moving the insulated electrical conductors into the insulation-displacement contacts thereby effecting electrical connections between the insulation-displacement contacts and the insulated electrical conductors.

  • Patent number: 6265670
    Abstract: A grommet (150) is securable to and along an edge (46) of a wall (36) of an enclosure (10) to provide sealing about lengths of cable extending through recesses (48) along the edge (46). Grommet (150) includes a cable-receiving section (152) having a diaphragm (168) traversing each of the recesses and includes a virtual slit (156) extending from a thick top edge portion (154) and through the diaphragm to the thick bottom edge portion (158). A cable (22) is insertable into the virtual slit (156) until seated in and through the diaphragm; stiff opposed portions (176) of the top edge (154) of the grommet close after being deflected temporarily as the cable is urged therepast; thin resilient opposed strips (170) of the diaphragm (168) similarly close upon said cable being urged therepast, while strips (170) adjacent the cable remain deflected by and biased against the cable. Upstanding wall sections (50,52) of the enclosure wall (36) are received through apertures (164) through the grommet and latch therewith.

  • Patent number: 6102754
    Abstract: The invention is directed to a bus bar contact having a body with two mating ends. One of the mating ends has a tab contact portion. The other of the mating ends having a receptacle contact portion. The receptacle contact portion has a plurality of resilient fingers for providing an electrical interface. The resilient fingers are stamped and formed from the body member wherein adjacent resilient fingers are sheared from each other thereby removing no material from between the adjacent resilient fingers.
