  • Patent number: 4845307
    Abstract: A wildlife guard, designed to prevent an electrically grounded animal, such as a bird or small mammal, from contacting energized electrical equipment. A one-piece construction fabricated from an insulating material, such as a high-density polyethylene, the wildlife guard can be installed on energized electrical equipment using standard live-line tools, thereby obviating the need to shut down the electrical power. The guard includes inner protrusions to fit below the topmost skirt of an insulator bushing, outer protrusions to be grabbed by a live-line tool, and a lengthwise slot through which a conductor is forced during installation.

  • Patent number: 4453034
    Abstract: A core grip for use in conjunction with a conduction cable having an outer conductor and core element in a hollow elongated compression valve wherein the grip is disposed on an end portion of the core of the cable after the outer conductor has been stripped away and the compression valve is disposed about the grip and is crimped into an engagement with the grip which in turn mechanically engages the core wherein the core grip is formed from two separate semi-circular cylindrical halves made of a deformable metal which when joined together from a solid cylindrical grip having an axial core therethrough coated with grit which is adapted to receive the core of the cable.

  • Patent number: 4214806
    Abstract: An electrically conductive connector adapted to be releasably coupled with a stud to form an electrical connection. The connector includes an electrical terminal with an electrically conductive terminal aperture. The aperture has a larger diameter than the stud so as to facilitate introduction of the stud therein. A set screw is threadedly mounted on the electrical terminal in position to be actuated from the exterior of the electrical terminal and to be reciprocally passed across the aperture to engage the stud inserted therein and form a fixed electrical connection between the stud and connector. Release of the set screw permits the stud to be removed from the connector. The aperture has a configuration to permit it to cooperate with the set screw and stud to stabilize the interconnection therebetween. This is particularly true when the connection is subjected to forces acting other than along the axis of the set screw that otherwise could cause loosening of the interconnection between stud and connector.
