Definitions

  • a difiiculty in cold-forging techniques occurs in attempting to join large-sized wires (e.g., 1/ 0 wire and larger), especially in remote locations such as might be experienced by a power company lineman.
  • One remedy has been the development of a powder-actuated tool to achieve the high crimping forces necessary in such applications, and concurrently reducing the size of the device required for effecting the cold-forged connection.
  • FIGURE 1 is a perspective view illustrating a preferred embodiment of the invention, clamping a pair of wires
  • FIGURE 2 is a sectional view, taken through plane 22 on FIGURE 1, prior to actuation of the device;
  • FIGURE 3 is a View similar to FIGURE 2, illustrating the device after it is actuated.
  • FIGURES 4-6 are views corresponding to FIGURES 13, illustrating one embodiment of a means for restraining the piston against longitudinal movement.
  • the connector comprises an outer C-shaped clamp member, generally indicated C, adapted to accommodate a pair of wires W and W.
  • each of the wires In assembled position, each of the wires is adapted to fit into the upper and lower bights, respectively, of the clamp member C.
  • a wedge-shaped block B is likewise adapted to fit between the Wires W and W and, due to the taper on the upper and lower surfaces of the block, the block is designed to secure the wires W and W in the clamp means B.
  • One of the Wires for example, might be the through-wire strung between utility poles, and the other wire would be a tap wire.
  • the block -B comprises a body member having arcuately-curved portions 12 and 14 on opposed surfaces of the body member. These surfaces 12 and 14 are concave and designed to match the particular sized Wire designed to be connected.
  • the body member 10 (FIGURE 2) also includes an opening 16 axially aligned with the body member.
  • aperture 16 is undercut at 18 to provide a piston chamber, which is partially disposed within the body member 10.
  • the piston chamber 18 may be lined with stainless steel 19 for protective purposes and contains an explosive charge 19 therein.
  • a piston rod 20 partially extends through the aperture 16 and is secured to a piston 22, movably fitted within the chamber 18.
  • a pair of washers 24 and 24' surround the piston rod 20 and have an outer diameter equivalent to the inner diameter of the piston chamber 18.
  • the explosive charge 19 is disposed between the washers 24, 24' and retained in place by the piston 22.
  • the other end of the piston rod has a baling eye 26 which is capable of being secured to means for restraining the piston against longitudinal movement.
  • One way of restraining longitudinal movement of the piston comprises a tongue-shaped member 28 (FIGURES 46) projecting integrally from one end of the clamp member C.
  • a pin 30 extends laterally from the tongue and provides a pivot for the baling eye 26. It is noted that this arrangement permits the piston rod 20, piston 22, and the wedge block B to pivot about the pin 30 while restraining the piston rod 20 and piston 22 against longitudinal movement.
  • Actuation means includes a second aperture 32 which forms a passageway between the chamber 18 and the outer surface of the block B.
  • a bushing 34 is threaded into this aperture and a firing pin 36 is slidably disposed within the bushing 34.
  • a washer 37 on the firing pin retains the firing pin in the bushing 34.
  • the inner end of the firing pin 36 is adapted to strike a primer 38 which is press-fitted into the bushing 34 and communicates with the interior of the piston chamber 18 through an aperture 39 between the piston 22 and the undercut portion.
  • FIGURE 2 When it is desired to secure a pair of wires W and W in conductive relationship, the device is assembled in the relationship illustrated by FIGURE 2.
  • the Wires are positioned within the C-shaped member with the body member B placed therebetween. Pivotal motion of the block B (FIGURE 5) facilitates positioning the wires within the C-shaped member.
  • the body member B is moved forwardly until it frictionally engages each of the wires W, W. In this position (FIGURE 2), the piston 22 is near the outer forward end of the chamber 18.
  • Detonation of the primer 38 by striking a blow upon the firing pin 36, causes the primer 38 to ignite the powder 19 in the chamber adjacent the piston 22. Since the piston rod 20, piston 22, and the outer shell C are all fixed relative to each other, the reaction force causes the body member B to be driven relative to the clamp C, thereby tightly engaging the wires W, W between the clamp C and the body member B. The force generated by the explosive results in wire deformation whereby the wire W is squeezed between the arcuate surface 12 and the corresponding bight of the C-shaped member to form a strong, intimate bonding of the material of the wire to the material of the connector. The same effect occurs with regard to the material of the wire W and the arcuate surface 14.
  • this device provides a simple means for securing large-sized wires together with the power-generating mean contained within the device.
  • a device for securing wires together comprising: a pair of relatively movable connecting members adapted to secure a wire therebetween, and explosively-operated means disposed in one of said members for causing relative motion between said members.
  • a device for securing wires together comprising: a C-shaped clamp, a wedge means adapted to fit into said clamp to retain wires therebetween, a chamber in said wedge, explosive means in said chamber, a piston in said chamber, means securing said piston to said C-shaped clamp, whereby detonation of said explosive means causes the Wedge to travel relative to the C-shaped member.
  • a device for securing wires including an outer clamp member, a wedge means adapted to fit into said clamp, a piston chamber in said wedge means, a piston in said chamber, a piston rod secured at one end to the piston and at the other end to the clamp and explosive means in said wedge for actuating the wedge relative to the clamp.
  • a connecting device for wire comprising: a C-shaped outer member, a wedge adapted to fit into said C-shaped member, a chamber extending axially of said wedge, piston means in said chamber, means securing said piston to said outer member, and explosively-actuating means in said wedge for driving said wedge relative to the piston.
  • An actuating device for utilizing explosively-generated power comprising: a cylinder, a piston disposed in said cylinder, a piston rod secured to said piston extending outside the cylinder, explosive means on the working side of the piston, and means for restraining the piston against axial movement whereby detonation of the explosive means causes the cylinder to move relative to the piston.
  • a wire-connecting device comprising: a C-shaped clamp, 21 wedge means adapted to fit into said clamp, a cylinder in said wedge, a piston in said cylinder, means for securing said piston to said clamp, and means in said device for driving said wedge relative to said clamp.
