Definitions

  • the invention relates to a method for producing an electrically conductive connection between an electrical flat conductor embedded in insulating material and a further electrical conductor, using a metallic contact part with piercing claws at one end and a web running in the direction of the other end, with which the contact part is determined by means of the piercing claws while penetrating the insulating material on the flat conductor and with which the further conductor is connected to the free end of the contact part.
  • Piercing claw contact parts are available on the market. They are used in the stripping-free connection technology, regardless of the cross-sectional shape of the conductor. These contact parts have the advantage that the often complex stripping is not necessary.
  • the piercing claws not only have to penetrate the insulating material of the conductor when using these contact parts. Rather, they must have good, firm contact with the leader himself, especially in the long term. For this reason, the contact parts are fixed to the conductor with considerable force, as a result of which the insulating material is firmly enclosed or pressed in by the piercing claws.
  • the invention has for its object to provide a method by which, when using a contact part with piercing claws for contacting a flat conductor, the risk of damage to the same is prevented and a perfect electrical connection is ensured in the long run.
  • the contact part is fixed to the insulated flat conductor using the piercing claws, as in previous technology.
  • this connection is made via the stripped end of the flat conductor, which is soldered or welded to the web of the contact part, for example.
  • the connection point is through the piercing claws previously fixed on the insulated part of the flat conductor are protected against tensile loads. In this way, a permanently good electrically conductive connection is established between the flat conductor and the contact part.
  • the tight fit of the contact part on the flat conductor is also retained since the insulating material is not pinched by the piercing claws. It therefore does not flow out of the stop. Because of the low pressure with which the piercing claws are attached, the risk of damage to the flat conductor is also avoided.
  • the contact part 1 shown in Fig. 1 consists of an electrically highly conductive deformable metal, for example of a copper alloy. It has piercing claws 2 at one end and an attachment part of any design at its other end, which in the exemplary embodiment shown is designed as a sleeve 3. However, a U-shaped fastening part could also be present, for example. A web 4 connecting the same is located between piercing claws 2 and sleeve 3.
  • the contact part 1 is to be used for the electrically conductive connection of an insulated flat conductor 5 and a further conductor, which in the exemplary embodiment shown is designed as a round, insulated stranded conductor 6.
  • This connection is established, for example, as follows: The flat conductor 5 is stripped at its end. Then the contact part 1 is fixed by means of its piercing claws 2 on the flat conductor 5 so that the piercing claws 2 penetrate the insulation thereof. This is carried out at a relatively low pressure, which only has to be sufficient to push the piercing claws 2 through the insulation of the flat conductor 5 and to deform them to such an extent that there is a firm hold. The ends of the piercing claws 2 can also be deformed until they come into contact with the flat conductor 5, but only up to its surface, without penetration thereof.
  • any insulated electrical conductor can be defined in any manner as a continuing conductor.
  • a solder is expediently applied to it after stripping.
  • the contact part 1 can then be fixed by means of its sleeve 3 on the stranded conductor 6, for example by squeezing. By applying heat during or after the squeezing, the solder is liquefied and sleeve 3 and Stranded conductors 6 are additionally soldered to one another.
  • a protective body 8 can be sprayed around the entire connection point, which is indicated in FIG. 3 by a dash-dotted line.
  • the tight fit of the contact part 1 on the flat conductor 5 is supported by the protective body 8.
  • the entire connection point is also enclosed in a moisture-tight manner.
  • the described method is suitable for connecting single conductors. However, it can also be used for flat conductor ribbon cables in which two or more flat conductors 5 are arranged next to one another. Such a ribbon cable consisting of two flat conductors 5 is indicated by dashed lines in FIG. 4. Each individual flat conductor 5 is then connected to a further conductor using the method described.
