  • Patent number: 4836805
    Abstract: The present invention teaches a novel device that electrically connects conductors from a cable to the electrical contacts of a plug by means of a single fastener. The device comprises a shell, a plug assembly carried by the shell. The plug assembly is capable of mating engagement with other electrical contacts and has receiving means for receiving electrical conductors. A single fastener holds the terminals of the conductors in electrical connection with the electrical contacts. The single fastener includes a movable carriage on which is mounted a nut through which a screw is threaded with a head with a flange that is engaged with the wall of the plug assembly so that when the screw is rotated, the carriage moves so as to decrease or enlarge a chamber in which the conductor terminals and a portion of the electrical contacts are situated.

  • Patent number: 4060305
    Abstract: An electrical wiring device is provided combining a strip gauge, a loop forming gauge and a wire-restraint which are coordinated to form a loop in a bare end of a solid insulated conductor wire at a location where insulation on the wire extends into the wire-restraint when the loop is secured under a terminal binding screw. The stripping gauge comprises a marking molded on the device and indicating the length of insulation to be removed from the wire prior to forming the loop in the bare end of the wire. The loop-forming gauge comprises side walls defining a cavity in the body of the device and a rounded shoulder formed at an upper end of said cavity. The bare end of the wire is confined within the cavity while the bare end of the wire is bent over the rounded shoulder into the form of the loop in the wire. The wiring device also includes wire-restraints which engage with insulation on the wire when the loop is secured under the binding screw.
