  • Patent number: 5690516
    Abstract: A slip-fit electrical connector for a threaded transformer stud has a stepped or key type stud hole which includes an oversize unthreaded circular hole on top and a slightly smaller intersecting hole on the bottom. The bottom hole has threads matching those of the stud and a jam screw forces the threaded stud into intimate contact with the threads of the smaller hole, such contact extending over a substantial arc. The connection provides a tight and improved electrical connection having simplicity of installation.

  • Patent number: 5533912
    Abstract: A submersible set screw connector has a conductive metal block with a series of blind conductor holes and corresponding set screws to clamp and secure the conductor ends to the block. The connector is provided with a waterproof case which includes elongated grommet receiving sleeves for each conductor. Access to the set screws is provided through cylindrical projecting ports, each of which includes a waterproof plug. Each plug is tethered to the case so it can not be lost. The tether extends from a small hole in a radial tab on the plug to a small hole on a fin projecting from the case. The tab keeps the tether radially outside the cylindrical projecting ports. The plug and port are configured to interfit to form a tight seal.

  • Patent number: 5199905
    Abstract: A connector bar for use in above grade pedestals for the distribution for underground electrical power to residential housing includes a body member having a pair of completely enclosed cable openings for receiving the main power line cables and partially enclosed wire openings within the body member for receiving distribution cables. Each distribution cable is trimmed to the proper length by placing it adjacent the connector bar and cutting the connector approximately flush with the top of the bar and the insulation is trimmed from the cable at a location just below the connector bar. After these steps have been accomplished, the cable is installed into the connector bar by laterally placing it into the partially enclosed opening and securing it in place by means of the set screw.
