Definitions

  • the invention relates to an insulation displacement terminal for connecting an electrical jumper wire, the jumper wire being able to be pressed into a clamping slot formed between two clamping legs of the insulation piercing formed from flat material in such a way that the insulation of the jumper wire is cut and the inside of the clamping legs resiliently on the metallic core of the jumper wire issue.
  • Such an insulation displacement clamp is, for. B. become known from DE-PS 20 07 487.
  • the inner sides of the clamping legs are aligned parallel to each other, so that there is a linear contact with the core wire.
  • the clamping legs are deflected in the material plane. In this direction, however, their elasticity is limited, so that jumper wires of different diameters can only be connected in a limited bandwidth.
  • one of the two clamping legs is deflected at its foot end by a bending edge lying transversely to the longitudinal direction in the material plane with respect to the other clamping leg by approximately material thickness.
  • the two clamping legs are separated from one another in the clamping area by a shearing process.
  • Such an arrangement enables the two clamping legs to be spread apart so far perpendicularly to the material thickness when the jumper wire is pressed in that jumper wires of considerably different diameters can be clamped on.
  • the clamping limbs, for. B. are supported in a housing of a terminal block, which may be with constructive additional effort and limitation of the constructive design options.
  • the invention has for its object to enable the connection of jumper wires of very different diameters in a simple manner with high contact reliability.
  • At least one inside of the clamping leg is no longer flat but edge-shaped on the jumper wire core. This is notched slightly even with low spring force and contacted securely. Due to the lower spring force, the spring legs can be made more elastic. If the inner sides are deflected sufficiently out of the plane of the material, the corresponding clamping leg can be rotated about its longitudinal axis when the jumper wire is pressed in, so that the clamping width can also be varied considerably without the clamping force changing significantly.
  • clamping legs are sufficiently wide in the clamping area, it is expedient to bend them within the clamping area in order to achieve a sufficient twist and tip effect. However, if the clamping legs are very narrow in relation to their thickness, they are difficult to bend. They can then be permanently twisted between the foot end and the clamping area, so that the desired tip effect is also achieved.
  • the development according to claim 5 hinders the bending of the jumper wire between the offset limbs.
  • two jumper wires can be connected to an insulation displacement terminal, which is particularly advantageous for distributors in telecommunication systems in which changes in the wire routing can be made without interruption.
  • a cutting clamp 1 made of flat material has two elongated clamping legs 2, which are separated from one another by a central cut 3, which extends in the longitudinal direction of the cutting clamp 1. This is connected to the free end of the clamp kel 2 narrowed to a clamping slot 4 into which the jumper wire to be connected can be pressed.
  • the mutually facing inner sides 5 of the clamping legs 2 are bent out of the material plane by a longitudinal edge 6 parallel to the clamping slot 4, so that the inner sides are rotated by approximately 45 ° to the material plane.
  • the two clamping legs 2 are bent at their foot ends by a transverse edge extending in the material plane transversely to the clamping slot by approximately the material thickness.
  • an insulated electrical switching wire 7 is pressed into the clamping slot 4 (FIG. 3) between the clamping legs 2 from the free end.
  • the jumper wire insulation has been cut.
  • the mutually facing edges of the inner sides press into the contact wire core in a contact-making manner.
  • notches are offset.
  • the two clamping legs 2 have been pressed apart so far that the width of the clamping slot has adapted to the jumper wire thickness.
  • the insulation displacement connector 1 is inserted into a housing part 12 which is provided on both sides of the insulation displacement connector 1 with two holding slots 11 for the jumper wire 7 which are perpendicular to the latter. This is hardly bent when pressed between the clamping legs 2.
  • the clamping legs 8 of a similar insulation piercing are essentially in the material plane. Only the inner sides are bent out in the opposite direction along the longitudinal edge 6, so that the mutually facing inner edges can engage on the jumper wire offset from one another.
  • another insulation displacement clamp 9 has two Clamping slots that are formed between three clamping legs 10.
  • the outer clamping legs are twisted in themselves, the middle clamping leg is curved in the clamping area around the central axis of the insulation piercing 9. In addition, it is bent out of the material plane at its foot end and offset to the outer clamping legs.
  • a switching wire 7 is pressed in like in FIG. 4 between the middle and one of the outer clamping legs 10 and is clamped in contact-making manner between the inner edges thereof facing each other. Irrespective of this, an additional jumper wire can be pressed into the other clamping slot in the same way.
