Definitions

  • the present invention relates to a ligature for fixing a cable in the upper groove of a rigid insulator.
  • each branch has an intermediate part in an arc, the radius of curvature of which is substantially that of the bottom of the lateral groove, passes through a ring common to the two branches, then is wound in a spiral around the cable.
  • the other end of each of the branches has substantially the shape of a loop, the two loops being arranged on either side of a part housed in said groove, and the assembly being held by a clamping means.
  • each branch is formed by at least one metal wire folded in the middle so as to form said loop. After this, the two metal wires can be joined to one another, thus forming a ribbon which is spiraled around the cable.
  • the object of the present invention is to adapt the preceding ligature to an insulator, the dielectric of which has a lateral groove and an upper groove, the cable being located in the upper groove.
  • the subject of the invention is a ligature for retaining an electrical conductor in the upper groove of a rigid insulator also having a lateral groove, comprising two branches substantially symmetrical with respect to a plane of symmetry of the insulator orthogonal to said cable , each branch having its first end in the form of a spiral attachment for said cable, characterized in that the second end of each branch has substantially the shape of a loop and is held in the lateral groove of the insulator by a clamping means, the first end of the branch intended to be spiraled on the cable passing through a first ring housed in the lateral groove of the insulator then in a second ring housed in the upper groove.
  • each branch consists of at least one metal wire folded in the middle so as to form said loop.
  • the first ring occupies substantially a half-circumference of said lateral groove.
  • the rings are formed by folding a metal wire and at each end of said rings, there is a superposition of at least one hairpin fold and an open turn.
  • the end portions of the metal wire forming the rings are slightly curved so as not to protrude.
  • the ligature is made of spring wire, preferably made of stainless steel or alumoweld, and consists of two branches 5 terminated at one end by a loop 6 and at the other by a spiral part 7.
  • a first ring 8 curved in half -circle is arranged in the lateral groove of the insulator, its ends being substantially diametrically opposite.
  • a second ring 9 of elongated shape is arranged in the upper groove.
  • Each branch 5 crosses a loop of the ring 8 and the loop of the corresponding ring 9.
  • the rings can be formed by bending a metal wire, and at each end there is a superposition of at least one fold in hairpin and an open turn.
  • Figure 3 illustrates such a ring.
  • the metal wire constituting the ring forms a fold 22, 23 in a hairpin which is superimposed with an open turn 24, 25.
  • the change of direction of the cable tie is therefore made by resting on two sections ring wire, which reduces the risk of damage to the ligation.
  • the two end parts 26, 27 of the wire forming the ring 1 are slightly bent so as to lie substantially in the same plane towards the "inside" of the ring, so that the end points 28, 29 do not injure neither the cable nor the insulator glass.
  • the wire used to constitute the ring can be alumoweld (aluminum + steel), or stainless steel, or Almelec.
  • each branch of the ligature can be formed by a wire of the same kind folded in the middle so as to form the loop 6. After this, the two metal wires can be joined, thus forming a ribbon which is spiraled around cable 10.
  • the clamping means for holding the loops in the lateral groove of the insulator comprises a rod 2 threaded at its ends and nuts 11.
  • this threaded rod can carry at least one elastomer part advantageously supported in the bottom of the lateral groove of the insulator.
  • this elastomer part can. be formed by a cylinder of appropriate section.
  • the cable 10 comes on the ring 9, the spiral parts 7 of the arms 5 are wound around the cable; the nuts 11 are tightened, which has the effect of blocking in the lateral groove the part of the ligature located between the rod 2 and the ring 8, and simultaneously applying the ring 9 against the upper groove of the insulator and hold the cable 10 against this ring 9.
  • the device prevents relative oscillatory movements of the cable and the ligature with respect to the dielectric and therefore prevents its wear as well as that of the cable and the ligature.
