  • Patent number: 4842548
    Abstract: A two-piece, all plastic connector for connecting a flexible conduit to an electrical fixture comprising a threaded connector cap having an extending wedging ring and a mating threaded connector body having a deflection ramp. The connector body is secured to an electrical fixture and the connector cap is loosely threadably engaged with the connector body. The conduit is inserted through an opening in the connector cap until it abuts the bottom of an annular cavity in the connector body. The cap is then tightly screwed onto the body such that the wedging ring is cammed, by the deflection ramp, into engagement with the conduit to securely grip the conduit. This arrangement provides a liquid-tight seal.

  • Patent number: 4738636
    Abstract: A four-piece all plastic strain relief connector for connecting an electrical cord to an electrical fixture comprising a body member and cap member which threadably engage to form a chamber. Located within this chamber is a collet and diaphragm assembly consisting of a flexible diaphragm snap-fit to a semi-rigid collet. The diaphragm has an aperture through which the cord passes and which forms a liquid-tight seal with the cord. The collet has a plurality of deformable tines for gripping the cord. One end of the body member is attached to a through hole in the electrical fixture. After the cord is inserted through the connector, the cap and body members are tightly screwed together such that a protrusion on the body deforms the tines on the collet into engagement with the cord. Teeth on the tines engage the plastic jacket of the cord to provide a secure grip.

  • Patent number: 4620061
    Abstract: An electrical enclosure including a box and a cover is molded largely of plastic, but is intended for use with metallic conduit. One or more metallic inserts is molded within the box, and also another insert is molded within the cover, to provide ground continuity to all fully or partially contained wiring or control devices as well as to provide ground continuity to conduit leading into the box. The electrical enclosure optionally is explosion proof, requires a minimum of machining, provides means for the harmless run-off of all static electrical charges, and exposes a minimum of metallic surface area to the surrounding atmosphere which may contain metal degrading contaminants.

  • Patent number: 4490576
    Abstract: A connector for connecting jacketed, metal clad cable to an electrical box includes a tubular metallic body with a stamped and formed retainer element preferably staked therein. This retainer element has an annular rim with radially inwardly directed fingers formed or bent toward the electrical-box end of the connector for permitting insertion of the cable therein preparatory to affixing the two together, for preventing withdrawal of that cable in the opposite direction, and also for providing an electrical grounding continuity. The connector also features an elastomeric compression grommet that compresses into the cable jacket upon the tightening of a nut onto the connector body. A Teflon washer between grommet and nut minimizes the frictional resistance therebetween as the nut is tightened onto the connector body.
