Patent number: 4836805Abstract: 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.Type: GrantFiled: November 10, 1987Date of Patent: June 6, 1989Assignee: Leviton Manufacturing Company, Inc.Inventors: John M.
