Definitions

  • the invention relates to an insulation displacement contact for contacting a cable wire transverse to the sleeve axis, in particular for cable wires in telecommunications technology, with at least one clamping slot on the circumference of the sleeve and with an insulation displacement contact inside the sleeve according to the preamble of claim 1.
  • An insulation displacement contact of the generic type is previously known from DE-32 36 867 A1.
  • This insulation displacement contact consists of a sleeve made of plastic, on the circumference of which two clamping slots are provided with a locking point and a metallic insulation displacement contact with a contact slot.
  • the insulation displacement contact is formed in two parts. When an insulated wire is pressed into the contact slot, the opposite sharp edges of the contact slot first cut through the wire insulation and then penetrate into the conductive core of the wire. With the insulation displacement contact, insulated wires can be connected without screws, soldering and stripping.
  • the insulation displacement contact can be installed free-standing on a surface or in a housing. Only cable cores with a certain diameter can be connected to this insulation displacement contact, since the cable diameter to be connected depends on the slot width of the contact slot and the clamping slot.
  • the invention is therefore based on the object of developing the insulation displacement contact of the generic type in such a way that cable cores with different diameters and also stranded conductors of different diameters can be contacted.
  • the invention provides that the contact legs of the contact slot are cut out of the jacket of the sleeve in such a way that an expansion of the clamping slot creates an expansion of the contact slot.
  • the sleeve cross section can have any shape. With a square cross-section, the sleeve can thus be mounted, for example, in a plastic in a manner that prevents it from twisting.
  • a high degree of contact reliability is achieved if the contact legs are arranged at an angle of approximately 45 degrees to the cable core axis, so that the sharp edges of the contact slot formed by the contact legs penetrate into the conductive core of the cable core at two diagonally opposite locations.
  • the contact legs are designed as jacket elbows, so that a surface contact occurs.
  • This surface contact offers the possibility of connecting the stranded conductor to the insulation displacement contact without damaging or cutting through the individual wires of the stranded conductor.
  • the first exemplary embodiment of the insulation displacement contact is shown in FIGS. 1 to 6.
  • the sleeve 1 of the insulation displacement contact has a round cross section, in the jacket 33 of which there is an axial clamping slot 5 extending over the entire jacket length of the sleeve 1 and a short separating slot 12 opposite the clamping slot 5 with a knife-like slot base 13.
  • insertion bevels 16 and 17 are provided.
  • the jacket 33 of the insulation displacement contact made of a metallic material is punched out of a sheet metal part and then bent into the desired shape.
  • rectangular jacket pieces 2, 3 are cut out in the middle region of the sleeve during the punching process.
  • the jacket pieces 2, 3 are cut free by means of U-shaped incisions 35 on two narrow sides 29 and on one long side 30.
  • the other long sides 30 of the jacket pieces 2, 3 form bending edges 31 around which the jacket pieces 2, 3 are bent into the interior of the sleeve 1 to form the insulation displacement contact 4 as contact legs 6, 7.
  • the contact legs 6, 7 are bent at opposite points, so that a contact slot 8 is formed between the side walls 14, 15 of the contact legs 6, 7, which are aligned.
  • the contact legs 6, 7 form an angle ⁇ of approximately 45 ° to the plane 34 of the clamping slot 5.
  • a cable wire 18 is inserted through the clamping slot 5 and the separating slot 12 between the insertion bevels 16, 17, through which the cable wire 18 is inserted centrally into the slots 5, 12.
  • the cable core axis of the cable core 18 lies exactly on the plane 34.
  • the cable core 18 is now pressed down by means of a tool (not shown), the clamping slot 5 for holding the cable insulation 22 corresponding to that The diameter of the cable core 18 springs open.
  • the two contact legs 6, 7 also spring open and thus enlarge the slot width of the contact slot 8 in accordance with the cable wire diameter to be connected.
  • the two contact legs 6, 7 can also form additional angles to the plane 34 of the clamping slot 5 and the contact slot 8. Such exemplary embodiments are shown in FIGS. 7 to 9.
  • FIG. 7 shows a sleeve 1 in which the contact legs 6, 7 form an angle of approximately 90 ° with the plane 34 of the clamping slot 5. In this way, a fork contact 36 is formed.
  • the contact legs 6, 7 form an angle ⁇ of 45 ° to the plane 34 of the clamping slot 8 and in Figure 9 also one Angle of 45 °, so that this creates triangular contacts 37, the contact legs 6, 7 away from the clamping slot 5 or directed towards them.
  • the triangular contact 37 according to FIG.
  • FIGS. 10 to 14 an insulation displacement contact with a surface contact 9 is shown, which is used in particular for connecting stranded conductors 23 (FIG. 13).
  • the development of this insulation displacement contact is shown in FIG. 14.
  • two upper and two lower slots 24, 25 running parallel to one another and at a distance from one another are punched out of a metal sheet, with cutting tips 26 being provided centrally in the upper slots 24.
  • the resulting between the upper and lower slot 24, 25 jacket pieces 2, 3 are bent at the bending edges 38 of the insulation displacement sleeve contact as jacket angle pieces 10, 11 inwards, so that two V-shaped contact legs 6a, 7a arise, the tips of which are exactly opposite and form the slot width of the contact slot 8.
  • This insulation displacement sleeve contact has like that The above-mentioned exemplary embodiments have a continuous, axial clamping slot 5 and a short separating slot 12.
  • the cutting tips 26 first cut through the insulation of the stranded conductor 23 until the slot walls 27 with the conductive individual wires 32 of the stranded conductor 23 are under pressure Come into contact and establish an electrical connection between the insulation displacement contact and the stranded conductor 23.
  • the stranded conductor 23 is thus connected without damaging or severing the individual wires 32.
  • the contact slot 8 springs up according to the diameter of the stranded conductor 23, so that stranded conductors 23 with different cable diameters can be connected.
  • the cutting tips can be offset from one another, so that the V-shaped contact legs 6, 7 have different leg lengths.
  • extensions 28 are attached at the bottom of the jacket 33, via which an insulation displacement sleeve contact can be connected to a second insulation displacement sleeve contact.
