Definitions

  • the present invention relates to a terminal or jointing clamp for an overhead cable, comprising two pairs of toothed jaws pressable against each other, a clamping screw for pressing the jaws against each other, and a moment transmission nut provided with a fracture point for turning the clamping screw.
  • the invention relates also to a moment screw, serving as a clamping element in a terminal or jointing clamp for a coated overhead cable and including a moment transmission nut provided with a fracture point.
  • An object of the invention is to provide a terminal or jointing clamp of the above type and a moment screw there-for, which are capable of achieving a voltage working ability without insulating the threaded portion of the screw from live jaws and which is further capable of accurately achieving a desired moment level.
  • the terminal or jointing clamp includes two pairs of opposite jaws 1, 2 provided with teeth piercing through the insulation.
  • the jaws 1 are included in a lower jaw element, which is axially coupled by way of a brace element 3 with an elongated rail 6 provided in turn with a threaded hole engaged by the threading of a clamping screw 5.
  • the clamping screw 5 has its top end provided with a hexagon head 7, which is embedded in a recess existing in an insulator block 8.
  • a portion of the insulator block 8 constitutes an insulation layer 9 surrounding the head 7.
  • the insulation layer 9 is surrounded by a hexagonal metal bushing 10, which in turn surrounds a moment transmission nut 11 below its fracture point 12.
  • a torsional force from the nut 11 to the head 7 is transmitted by way of the metal bushing 10 and the insulation layer 9.
  • the nut 11 is isolated from the hexagon head screw 5, 7, which functions as an actual clamping screw.
  • the moment transmission nut 11 be provided with a metallic cutout 12 for determining accurately a desired moment level.
  • the upper jaw element 2 When tightening the moment screw by turning the nut member 11 above the cut-out, the threads of the screw 5 pull the lower jaws 1 upwards through the intermediary of the elements 6, 3.
  • the upper jaws 2 bear against the screw head 7 through the intermediary of the brace element 4.
  • the upper jaw element and its brace element 4 are provided with a sufficiently loose hole for allowing the inclination thereof, as depicted in fig. 3. This enables the coupling of wires with varying thicknesses.
  • the upper jaw element 2, 2 is held in a top position by means of cams 16 engaging the ends of a housing or a box 13.
  • Reference numeral 15 designates wire openings included in the ends of the box 13.
  • the figure only shows the top portion 13 of the box or housing.
  • the insulation layer 9 is integral with the wide cap-shaped element 8 which closes an opening included in the top side of the terminal box 13, said opening being sufficiently large for enabling the inclination of the top half 13 of the terminal box relative to the moment screw, as depicted in fig. 3.
  • the top opening of the box 13 can be closed with a lid 14.
  • the lid 14 cannot be placed in position until the nut 11 is broken.
  • the joint can also be readily unclamped by removing the lid 14 and by unscrewing the nut 11 from the polygonal metal bushing 10.
