Definitions

  • the invention relates to a method for electrically conductive connection of the electrical flat conductor of a flat conductor strip line, which have an approximately rectangular cross section and are embedded with distance and parallel to each other in a common insulation, with round conductors, which have a round electrical conductor with a circular cross-section which is surrounded by an insulation ( DE 198 44 869 A1 ).
  • Such a method is used, for example, for electrically connecting the flat conductors of a flat-conductor ribbon cable wound in a winding tape cassette-referred to below as "FL-BL" -with further round conductors
  • FL-BL wound in the winding tape cassette follows, for example, the rotational movement of a steering wheel without the use of sliding contacts.
  • the invention has for its object to simplify the above-described method while ensuring that the joints between the conductors are protected against mechanical stress.
  • the electrical conductors to be connected are directly connected to each other, preferably by welding or soldering.
  • a separate, to be attached between the respective conductors connecting element is therefore no longer required.
  • the connector consisting of two parts to be joined together, the FL-BL is also pressed against the round conductors, so that a relative movement between the FL-BL and the round conductors is excluded.
  • the joints of the respective conductors on the connector protruding ends of FL-BL and round conductors are thereby protected against tensile stresses exerted on the FL-BL and the round conductors on the other side of the connector remote from the joints.
  • connection point between the flat conductors of a FL-BL and round conductors is explained below with reference to an exemplary embodiment of a connection point between the flat conductors of a FL-BL and round conductors.
  • a flat conductor stripline 1 - hereinafter referred to as "FL-BL" - has in the in Fig. 1 illustrated embodiment, for example, four flat electrical conductors 2 with a rectangular cross-section. They are preferably made of copper. The flat conductors 2 are embedded in parallel and at a distance from each other in a common insulation 3, which consists for example of two laminated around the flat conductor 2 around sheets of insulating material.
  • An in Fig. 2 illustrated circular conductor 4 has a round electrical conductor 5 with a circular cross section, which preferably also consists of copper. It can be designed as a solid conductor or as a stranded conductor with a plurality of individual wires.
  • the conductor 5 is surrounded all around by an insulation 6, for example, produced by extrusion.
  • the two parts to be joined together of a connector used in the process for example, from the 3 and 4 out.
  • the two parts are connected to each other in the assembled state with advantage by latching elements. They consist of a mechanically stable insulating material.
  • a first part 7 of the connector is equipped with a number of mutually parallel grooves 8, which serve to receive insulated round conductors 4.
  • the distance of the grooves 8 from each other depends on the distance between the flat conductors 2 in the FL-BL 1. He is in Fig. 3 for the sake of clarity and analogy to Fig. 6 compared to the FL-BL 1 after Fig. 1 shown for six grooves 8.
  • the dimensions of the circular conductor 4 to be used in the method are known.
  • the depth of the grooves 8 in the first part 7 of the connector is such that the round conductor 4, as it out Fig. 6 emerges, protrude from the grooves 8 and thus protrude beyond the profile of the first part 7 of the connector.
  • the second part 9 of the connector has at least on one side a substantially flat surface which is intended to bear against the FL-BL 1.
  • On this side of the second part 9 of the connector protruding projections protruding from its surface can be mounted, which engage in the assembled state in prepared recess of the FL-BL 1 and position them in the correct position.
  • the second part 9 may be equipped with a window 10 in an extension, which protrudes over the first part 7 with the connector assembled, through which the ends of FL-BL 1 and round conductors 4 are accessible for connection purposes.
  • the method according to the invention is carried out, for example, as follows:
  • the ends of round conductors 4 and FL-BL 1, which are to be connected to one another in an electrically conductive manner, are advantageously stripped off, so that the bare flat conductors 2 on the one hand and the bare round conductors 5 on the other hand are available.
  • a given number of round conductors 4 in grooves 8 of the first part 7 of the connector is inserted so that their stripped ends protrude with a predetermined length from the same.
  • the FL-BL 1 can be placed on the round conductor 4 so that their stripped area with bare flat conductors 2 over the stripped round conductors 5 and preferably rests on the same.
  • the second part 9 of the connector can be snapped onto the first part 7 of the same latching, so that the FL-BL 1 is pressed against the circular conductor 4, which - as already mentioned and in Fig. 6 shown - protrude from the grooves 8 of the first part 7. A relative movement between FL-BL 1 and round conductors 4 is then no longer possible.
  • the immovable position of FL-BL 1 and round conductors 4 in the connector can be further improved by a primer which can be applied to the FL-BL 1 and / or round conductors 4 in the region of the connector.
  • hooks 11 and 12 (FIG. Fig. 6 ), which engage in the mounting position in recesses or undercuts of the part 9.
  • the connector goes out including FL-BL 1 and round conductors 4 Fig. 7 out.
  • the FL-BL 1 is first inserted into the second part 9 of the connector, which has a kind of receiving space, which can be sized in accordance with the FL-BL 1 and limited laterally.
  • On the corresponding surface of the second part 9 of the connector can - as already mentioned - be mounted by the same protruding projections which engage in inserted FL-BL 1 in recesses thereof, which are mounted in a positionally accurate in a prefabrication.
  • the FL-BL 1 then automatically has the correct position in the connector, which is completed by snapping the second part 9, which has been fitted with the FL-BL 1 as described, onto the first part 7.
  • Both the flat conductor 2 and the round conductor 5 are - as mentioned above - preferably stripped before mounting in the connector at their ends. But the conductors 2 and 5 can also be stripped after fixing FL-BL 1 and round conductors 4 in the connector.
  • the thus bare conductors 2 and 5 are finally electrically conductively connected to each other, in each case a flat conductor 2 with a round conductor 5. They are in particular welded or soldered together. This can be done with advantage in the region of the window 10 in the second part 9 of the connector, if the part 9 has a corresponding extension.
  • the electrical connection of the conductors 2 and 5 can therefore be made particularly simple, because no tensile stress can be exerted on the conductors 2 and 5 because of the fixing of FL-BL 1 and round conductors 4 in the connector. This advantage also applies and in particular for the completed joints of the conductors 2 and 5.
