Definitions

  • the present invention relates to a device for producing a branch from a single insulated wire of a multi-conductor cable, wherein a first and a second clamping element can be brought into clamping contact with one another by means of a screw arrangement.
  • branch terminal which consists of detachably connectable segments, spacers being provided between the individual segments.
  • the present invention has for its object to provide a device for branching a single insulated wire of a multi-conductor cable, which can be assembled in a very simple manner with a minimum number of individual parts without much time.
  • the features according to the invention result in a simple clamping contact of the main wire by means of a screw with simple assembly.
  • the distance between the tilting support and the recesses for the main wire ensures high clamping forces.
  • a device shown in FIGS. 1 and 2 for branching a single insulated wire of a multi-conductor cable has a first 1 and a second 2 clamping element. These two clamping elements can be pressed against one another by means of a screw arrangement 3, so that a clamping contact arises between the individual elements 1 and 2.
  • the first clamping element 1 has a projection 5 through which a bore 4 runs. This hole is intended to accommodate a branch conductor.
  • a recess 7 is provided in the first clamping element 1. This recess is designed to span the main vein.
  • the second clamping element 2 each has a recess 15 and 9, the part-circular recess 15 forming the support part 8 for the clamping element 1.
  • the radius of the recess 15 corresponds approximately to the radius of the projection 5, so that when the clamping contact is produced, the projection 5 is spanned by the recess 15 along a wide area of its circumference.
  • the projection 5 can be rotated about the drilling axis 6 in the recess 15, the recess 15 forming a tilting support 16. In the case of a clamp contact to be produced, this arrangement also guarantees the necessary anti-rotation protection.
  • the clamping elements are provided with an insulating surface coating.
  • the recessed clamping screws 3a make the proposed clamp very space-saving.
  • the assembly is also correspondingly simple:
  • a prepared branch conductor is guided through the bore 4 and clamped by means of a screw 13.
  • the clamping element with its recesses 7 and 9 is then pushed onto the main wire.
  • the screw 3a is tightened so that the clamping elements 1 and 2 are brought into clamping contact.
  • the annular cutting edges 11 penetrate into the insulating material of the main wire and displace it into the cavities 12. As soon as the annular cutting edges 11 have penetrated the insulating material, the clamping contact is produced.
  • the projection 5 of the clamping element 1 is nose-shaped.
  • the support part 8 of the clamping element 2 has a flat support surface 10, whereby the rounded nose creates a linear support of the clamping element 1 on the clamping part 2, about which the clamping element 2 can be pivoted about the tilting support 16 when tightened by means of the screw arrangement 3.
  • the clamping element 1 has an eye 14 for the screw 13 for clamping the branch conductor in the bore 4.
  • a contact surface 10 is arranged on each side of the eye 14.
  • the arrangement of the projections 5 on both sides of the eye 14 prevents the two clamping elements 1, 2 from rotating relative to one another when the screw 3a is tightened.
  • the recesses 9 and 7 with the annular cutting edges 11 correspond to the embodiment variant shown in FIGS. 1 and 2, wherein the cavities 12 between the annular cutting edges 11 can also be semicircular in cross section in order to reduce notch stresses, as shown in FIG. 2a.
