Definitions

  • the invention relates to an arrangement for the electrically conductive connection of insulated electrical conductors, which are squeezed together at their stripped ends parallel to each other in a metallic crimping connector, wherein the crimping connector is arranged in an existing of insulating material, cup-shaped cap.
  • Such arrangements are available on the market. They are used, for example, for simple and space-saving electrically conductive connection of combined in wire harnesses electrical conductors.
  • the ends of the conductors to be connected are brought together and stripped and then the bare conductors are then connected to a metallic crimp connector.
  • the crimp connector is then insulated so that it can be integrated in the assembly of a cable harness or attached to a receptacle in the region of a mounted harness.
  • a cap made of soft polyvinyl chloride (PVC) is used, in which an adhesive is included and which is glued to the crimp connector.
  • PVC soft polyvinyl chloride
  • the PVC cap is mechanically sensitive and the glue can easily cause soiling and damage to the cap.
  • the invention has for its object to make the above-described arrangement so that a mechanically improved protection of the crimp connector without contamination and damage is achieved.
  • the cap of this arrangement is made of dimensionally stable plastic, so that the crimp connector is not only isolated in the same, but also protected against coarse mechanical stress.
  • the dimensionally stable cavity of the cap is matched in its dimensions to the dimensions of the crimp connector, so that the same is relatively tightly enclosed by the same after its insertion into the cap.
  • two clamping ribs are used in the cap, which are arranged on two opposite sides in the cavity thereof.
  • Fig. 1 is a section of a wiring harness shown in which a number of insulated electrical conductors 1 is combined into one unit.
  • To the wiring harness include a main strand H and side strands S, which lead to electrical consumers of a motor vehicle, such as headlights, taillights, sensors and actuators.
  • Individual conductors 1 of the main strand H and the side strands S must be electrically conductively connected or interconnected, for example, in the region of a schematically indicated channel K in order to be able to produce a continuous connection between the consumers and a voltage or signal source of the motor vehicle.
  • the relevant conductors 1 are for this purpose extracted from the composite of the wiring harness, with their ends parallel to each other, stripped at these ends and connected by a metal crimp connector 2 electrically conductive.
  • the crimp connector 2 is made of brass, for example. Thereafter, the crimp connector 2 is isolated to ensure undisturbed installation of the wiring harness in a motor vehicle.
  • a cup-like cap 3 is used made of a dimensionally stable plastic, which consists for example of polyamide or polypropylene.
  • the cap 3 has a dimensionally stable cavity 4 with appropriate wall thickness, which is adapted to the dimensions of the crimp connector 2 and at one end by a provided with openings D bottom 5 Fig. 5 ) is completed.
  • the perforations D are required for injection-technical reasons, to produce the cap 3 with all offal, for example, in one operation in an injection mold and then to demould.
  • two clamping ribs 6 and 7 which protrude on two opposite sides of the wall of the cap 3 forth in the cavity 4 and serve for locking the cap 3 on the crimp connector 2. They are advantageously integrally formed on the cap 3 with a thickness or wall thickness and a shape that allow an elastically resilient bending of the same.
  • the shape of the clamping ribs 6 and 7 goes for the Clamping rib 7, for example, from the perspective view according to Fig. 6 out. It is advantageously positioned in a corner of the cap 3 and has a curved course pointing into the cavity 4. Basically, a clamping rib is sufficient. But there may also be more than two clamping ribs.
  • the embodiment shown in the drawings with two clamping ribs 6 and 7 is the preferred embodiment.
  • two guide rails 8 are mounted in the illustrated embodiment, which serve together as a contact surface for the crimp connector 2 during and after attaching the cap 3 on the same.
  • a guide rail would be sufficient to produce the contact surface.
  • a spring element 9 is attached in the illustrated embodiment, which abuts in the end position of the crimp connector 2 at the same. The crimp connector 2 is thereby pressed against the guide rails 8 so that it can not move uncontrollably in the cap 3.
  • the arrangement according to the invention is produced, for example, as follows:
  • the crimp connector 2 is squeezed around by means of a tool so that it is firmly and immovably stuck on the ladders. He then advantageously has a curved extending upper surface 10 and a substantially flat lower surface 11.
  • This preferred embodiment of the crimp connector 2 is in cross section Fig. 3 out. But the crimp connector 2 may also have any other cross-sectional shape.
  • the cavity 4 of the cap 3 is in each case adapted to the cross-sectional shape of the crimp connector 2.
  • the cap 3 is attached after fixing the crimp connector 2 to the conductors 1 on the same.
  • the lower surface 11 is applied to the guide rails 8.
  • the clamping ribs 6 and 7, which - as already mentioned - are advantageously arranged in two opposite corners of the cap 3, bent in the mounting direction. They spring into their as a detent position serving starting position back as soon as the crimp connector 2 extends far enough into the cap 3.
  • the crimp connector 2 then takes the in Fig. 7 , which shows a cross section through the cap 3, shown position in the same one.
  • the cap 3 is latched by the clamping ribs 6 and 7 on the crimp connector 2. In this end position of the cap 3 and the crimp connector 2, the spring element 9 presses on the upper surface 10 of the crimp connector. 2
  • the cap 3 with the crimp connector 2 latched therein can then be placed on the cable harness and integrated into it.
  • the cap 3 can be equipped with advantage on its lower surface 11 outside with a holding element 12, by means of which they can be attached to a mounted on such a support holder.
