Definitions

  • the invention relates to an insulation displacement contact element according to the preamble of claim 1.
  • Such an insulation displacement contact element is known from DE-OS 3526707.
  • a disadvantage of this insulation displacement contact element is that the insulation displacement contact legs are too stiff, so that the insulation displacement contact element is not suitable for very thin, e.g. B. only 0.08 mm thick wires, e.g. B. for so-called enamelled wires can be used, which are cut by the cutting in the contact slot between the contact legs of the known insulation displacement contact element.
  • the object of the invention is to design an insulation displacement contact element of a defined gap width with simple means such that an insulation displacement contact can also be produced with very thin wires without the risk of the wires being severed.
  • the insulation displacement contact element 1 is made from a stamped sheet metal part and is part of an electrical contact piece which, in addition to the insulation displacement contact element 1, has at least one further connection element 4 for electrical contacting.
  • the contact pieces 5 shown in FIGS. 1 to 6 each have two identical clamping contact elements 2, 3, which are arranged parallel and at a distance from one another. Since the connecting element 4 is insignificant for the function of the insulation displacement contact element according to the invention, its spatial shape becomes within the scope of the description of the present Invention not dealt with.
  • An insulation displacement contact element 1 is made from a flat, flat, rectangular piece of sheet metal and has the longitudinal edges 6, 7 and the transverse edge 8 on the plug side; to the cross edge 8 opposite side of the sheet metal piece, the connecting element 4 is integrally connected.
  • a separating cut extending parallel to the longitudinal edges 6, 7 is made in the sheet metal piece, which in the region of the connection of the Connector 4 runs out in a circular hole 10.
  • the adjacent cut results in two adjacent insulation displacement contact legs 11, 12.
  • a piece is made in the direction of the hole 10 at a distance from the transverse edge 8 from the separating cut, an incision 13 extending parallel to the transverse edge 8 is made in the insulation displacement contact legs 11, 12, so that one each from the incision 13 to the hole 10 extending insulation displacement knife 14 results.
  • the length of the incisions 13 and thus approximately the width of the knives 14 is preferably at least the radius or half the width of the hole 10; however, it is preferably longer and can e.g. B. up to the length of a diameter or the width of the hole 10.
  • the resulting from the incisions 13 and the hole 10 IDC 14 are bent in the same direction from the plane of the sheet, preferably with z. B. two folding edges 15, 16, so that a contact gap 19 of defined dimensions between the knife edges 18 of the insulation displacement knife 14 is formed.
  • the bending of the insulation displacement knife 14 from the sheet metal plane is simple, so that a defined dimension of the insulation displacement contact gap 19 can be ensured. Furthermore, a plurality of fold edges 15, 16 ensures a soft spring force of the insulation displacement knife 14, which is dependent on the number of fold edges, so that the cutting edges of the knife cannot cut the wire.
  • simple means have succeeded in creating an insulation displacement contact element for thin wires, in particular for so-called enamelled wires.
  • the invention makes it possible to arrange two parallel free-standing insulation displacement contact elements 2, 3 on a contact piece 5 (FIGS. 1 to 3); the invention even enables a wall 21 to be provided between two opposing insulation displacement contact limbs 2 and 3, so that an insulation displacement region of U-shaped cross section is of high intrinsic stability without the spring forces of the insulation displacement blade 14 being impaired thereby.
