Definitions

  • the invention relates to a wire connector for cable cores, in particular telecommunication cables, according to the preamble of claim 1.
  • a wire connector of this type is previously known from DE-23 28 505 A1.
  • insulation displacement contacts are used in the longitudinal center of the lower housing part in two parallel guide channels.
  • two housing upper parts connected to the lower housing part via film hinges are provided which, when latched to the lower housing part, press the cable wires inserted into the contact slots of the insulation displacement contacts by means of the insertion webs into the contact slots of the insulation displacement contacts.
  • a connection splice between two cable wires passing through the wire connector or a branch splice can be created in which only one cable wire runs through the wire connector, whereas the other cable wire outside the wire connector must be cut off.
  • the disadvantage here is that special cutting tools are required to cut the cable cores and that there is a risk of short circuits when cutting.
  • the invention is therefore based on the object of providing a wire connector of the generic type which can be used both for producing a connection splice and a branch splice without requiring special tools for cutting off the cable cores.
  • an additional separating element is fitted onto the lower part of the housing, which is provided with separating webs for separating the cable cores which initially run through the wire connector.
  • the wire connector consists of a lower housing part 1, an upper housing part 2 that can be snapped onto it and an additional separating element 3 that can be snapped onto the lower housing part 1, and insulation displacement contacts inserted into the guide channels 4 of the lower housing part 1 5 and cutting blades 6.
  • the lower housing part 1, the upper housing part 2 and the separating element 3 are made of plastic.
  • the insulation displacement contacts 5 and the separating knife 6 consist of an electrically conductive, metallic material.
  • the lower housing part comprises four adjacent guide channels 4 for the insertion and connection of two pairs of cable wires 7, 8.
  • the insulation displacement contacts 5 and separating knife 6, which are arranged at a distance from one another in a guide channel 4, are connected to one another via a web 9 (FIG. 2).
  • a supporting wall 10, 11 for the cable cores 7, 8 is formed in each guide channel 4 in front of and behind the insulation displacement contacts 5 and the separating knife 6.
  • the insulation displacement contacts 5 of two adjacent guide channels 4 are connected to one another in an electrically conductive manner.
  • the insulation displacement contacts 5 are arranged at an angle ⁇ between 30 ° and 60 ° to the longitudinal axis of the guide channels 4, two adjacent insulation displacement contacts 5 being arranged at opposite angles ⁇ and in the longitudinal direction of the guide channels 4 offset from one another.
  • the upper housing part 2 can be locked with the lower housing part 1 in two different positions, for which purpose the upper housing part 2 must be rotated by 180 ° about its vertical axis relative to the lower housing part 1.
  • the upper part of the housing 2 is provided on its underside with insertion webs 12 for the cable wires 7, 8, which insertion webs 12 run parallel to the guide channels 4.
  • the press-in webs 12 form transverse slots 13 for the area of the insulation displacement contacts 5, which enable the insulation displacement contacts 5 to penetrate while simultaneously pressing the cable wires 7, 8 into the contact slots of the insulation displacement contacts 5.
  • the insertion webs 12 form dividing webs 14 with dividing slots 15, in which the dividing knives 6 engage.
  • the upper housing part according to FIGS. 1 and 2 is snapped onto the lower housing part 1 in such a way that the separating slots 15 can accommodate the separating knives 6 and the transverse slots 13 the insulation displacement contacts 5.
  • the cable wires 7, 8 to be connected are inserted into the guide channels 4 of the lower housing part 1 and, when the upper housing part 2 is pressed on and locked, are pressed into the contact slots of the insulation displacement contacts 5 by means of the insertion webs 12 and cut off at the separating knives 6 at the same time by means of the separating webs 14 , so that a connection splice is formed between the pairs of cable wires 7, 8.
  • the support walls 10 within the guide channels 4 are deformed, as shown in Fig. 2.
  • FIGS. 3 and 4 show the wire connector in the first embodiment as a branch splice.
  • the upper housing part 2 is locked in position rotated by 180 ° about its vertical axis with the lower housing part 1.
  • the dividers 14 with the dividing slots 15 do not come into engagement with the dividing knives 6, but the dividers 14 only press the cable wires 7, 8 into the lower housing part 1.
  • FIGS. 5 and 6 now show the conversion of the branch splice according to FIGS. 3 and 4 into a connection splice.
  • the separating element 3 is snapped onto the lower housing part 1 in addition to the upper housing part 2.
  • the separating element 3 has additional separating webs 18 with separating slots 19 and incisions 21 between the separating webs 18, into which the additional dividers 16 of the upper housing part 2 penetrate.

  • the separating webs 14 with the separating slots 15 are located to the right of the pressing-in webs 12 and the separating webs 16 with separating slots 17 are located to the left of the pressing-in webs 12.
  • the flaps 20 arranged alternately with the additional dividers 16 of the upper housing part 2 cover the dividers 18 with dividing slots 19 of the dividing element 3.
  • the flaps 20 are displaced from the dividers 18 of the dividing element 3, so that the separating slots 19 of the separating webs 18 can come into operative connection with the separating knives 6.
  • the upper housing part 2 has two locking webs 22 on its two narrow sides, which fit into correspondingly adapted locking slots 23 of the lower housing part 1 intervene and click into place.
  • the separating element 3 has a latching web 24 on each of the narrow sides, which likewise engages in the latching slots 23 of the lower housing part 1.
  • FIGS. 8 to 10 The second embodiment of the wire connector is shown in FIGS. 8 to 10.
  • This consists of a lower housing part 31 and two identical upper housing parts 32 which can be locked with this and a separating element 33 which can be locked with lower housing part 31.
