  • Patent number: 4821161
    Abstract: A light fixture suitable for attachment without a junction box is shaped as a one piece thermoplastic cylindrical receptacle with one end closed. An inner surface of the closed end forms an axially extending molded socket in which a bulb screwshell is centrally disposed and to which a light reflector is attached. At the outer surface of the closed end is a circular cavity containing all the electrical connections, including the contacts, the wire terminals and the cord guides for holding an electrical cord in position. Conductive metal strips connect the contacts and the wire terminals and are recessed in the circular cavity. The cavity is covered by a cap with a protruding annular rib which when fastened bends the electrical cord supported by the cord guides into clamping engagement with the outer surface of the closed end for securing the cord against pull and strain forces on the wire connectors.
