Definitions

  • the invention relates to an insulation displacement contact for making contact with an insulated cable core according to the preamble of claim 1.
  • the insulation displacement contact has two contact legs made of leaf-shaped, resilient contact material, between which a contact slot is formed which is delimited by the inner sides of the contact legs and to which a V-shaped wire insertion area is assigned.
  • the width of the contact slot is smaller than the diameter of the conductive core of the cable wire to be connected.
  • the insulation displacement contact is inserted in a plastic body at an angle to a clamping slot for the cable core, preferably at 45 °.
  • a cable core with thick insulation touches the sharp edges of the V-shaped wire entry area of the insulation displacement contact, which is at an angle to the longitudinal axis of the cable, when wiring, than a cable core with thin insulation.
  • the real contact force is smaller and the possible permissible deformation or deflection of the contact legs is greater than with cable core with thinner insulation.
  • the inside of the V-shaped wire insertion area does not have sufficient cutting force to cut the insulation.
  • the insides therefore slide on the insulation surface.
  • the contact force and the permanent deformation or deflection of the contact legs increase the deeper the cable core is pressed in.
  • the inside of the contact legs are so far from the initial position that the contact-spring travel is too small and the contact slot for the thin conductive core is too wide to contact the conductive core of the cable core .
  • the invention is therefore based on the object to provide an insulation displacement contact of the generic type, which both contacting cable cores with thick insulation and cable cores with a thin conductor core, in particular with a ratio of the insulation to the conductor core diameter larger as 3, safely and reliably manufactures.
  • the insulation displacement contact consisting of a metallic, sheet-like material comprises two contact legs 2, 3 which are spaced apart and form a contact slot 4 between their inner sides 13, 14.
  • a wire insertion region 7 merging into the contact slot 4 is formed with the inner sides 23, 24 of the contact legs 2, 3.
  • This consists of an enlarged insertion opening 17, in which the inner sides 23, 24 are arranged parallel to one another, and an essentially V-shaped centering opening 16, which adjoins the insertion opening 17 and extends up to the upper edge 15 of the contact slot 4 is.
  • inclined surfaces 8, 9 are attached, which extend between the rear side 19 and the front side 18 of the insulation displacement contact 1.
  • the inclined surfaces 8, 9 are mounted such that they either run out at the upper edge 15 of the contact slot 4, FIGS. 4 and 6, or within the contact slot 4, FIGS. 1 and 3.
  • wedge-shaped cutting of the centering opening 16 of the wire insertion area 7 forming cutting edges 10 and 4 cutting tips 20 are formed on the upper edges 15 of the contact slot.
  • the centering opening 16 has a circular insertion region 22.
  • the inclined surfaces 8, 9 run out within the contact slot 4, so that a cutting tip 20 is formed on each inner wall 13, 14 within the contact slot 4.
  • Each leg 2, 3 of the insulation displacement contact 1 has an inclined surface 8, 9 in the wire insertion area 7, which are arranged diametrically opposite one another, so that the cutting edges 10 and the cutting tips 20 are in each case on the front side 18 of the one leg 2 and on the Back 19 of the other leg 3 of the insulation displacement contact 1 are arranged.
  • FIGS. 2 and 4 show the second exemplary embodiment, in which the inclined surfaces 8, 9 run out at the beginning of the contact slot 4 of the upper edge 15, so that the cutting tips 20 are formed directly at the beginning of the contact slot 4.
  • FIGS. 5 and 6 show the third and fourth exemplary embodiments, in which the centering opening 16 is V-shaped and inclined surfaces 8, 9 are formed from rectangular surfaces 21 which, as in the exemplary embodiments described above, either according to FIG. 5 within of the contact slot 4 or according to FIG. 6 at the upper edge 15 of the contact slot 4.
  • the centering opening 16 does not have a circular insertion region 22.
  • connection of an insulation displacement contact 1 to a cable core 5 is explained in more detail below with reference to FIG. 7.
  • the cable core 5 is inserted from above into the wire insertion area 7, as indicated by the arrow A in FIG. 1.
  • the insulation displacement contact 1 is inserted at an angle of 45 ° obliquely to a clamping slot 25 in a recess 27 of a plastic body 28.
  • Clamping cams 26 for clamping the insulation 6 of the cable core 5 are arranged in the clamping slot 25.
  • the recess 27 firmly clamps the outer edges 29 of the contact legs 2, 3 and allows the inner edges 30 of the contact legs 2, 3 a free space of movement.
  • the distance between the parallel inner sides 23, 24 of the contact legs 2, 3 in the insertion opening 17 of the wire insertion region 7 is greater than the outer diameter D of the cable core 5.
  • the distance between the inner sides 13, 14 arranged parallel to one another, i.e. the width W of the contact slot 4 of the insulation displacement contact 1 is smaller than the diameter d of the conductive core 12 of the cable core 5.
  • the cable core 5 is centered on the contact slot 4, so that the conductive core 12 of the cable core 5 is inserted exactly in the center of the contact slot 4.
  • the cutting edges 10 first penetrate directly into the insulation 6 without the cutting edges 10 sliding on the outer jacket of the Cable 5 is possible. Furthermore, the oblique position of the insulation displacement contact 1 relative to the cable core axis B ensures that the diametrically opposite cutting edges 10 penetrate the insulation 6 of the cable core 5 offset. If the conductive core 12 of the cable core 5 is now pressed into the contact slot 4, the cutting tips 20 and the inner edges 11 of the inner sides 13, 14 penetrate the contact leg 2, 3 into the conductive core 12 of the cable core 5 and establish a contact connection between the insulation displacement contact 1 and the cable core 5.
  • the inclined surfaces 8, 9 advantageously ensure that the inner sides 13, 14 on the outer jacket of the insulation 6 are prevented from sliding in the wire insertion region 7.
  • the contact legs 2, 3 can thus not rotate relative to each other, which prevents widening of the contact slot 4. This ensures that the conductive core 12 is still cut from the inner edges 11 of the contact slot 4 even with a very small diameter.
