Definitions

  • Crimp contacts are widely used, particularly in automotive applications, but also in many other electrical engineering applications. However, crimp contacts only offer a form-fitting and force-fitting connection with a stranded conductor and are therefore not equally suitable for all types of metallic conductors. In particular, when copper is not used as the conductor material, crimp contacts have so far only rarely been used. Cohesive joining processes are generally used for aluminum conductors to connect them to contacts. Contact corrosion must also be considered when using different metals between the conductor and the crimp contact. For example, when using aluminum as a less noble metal than copper, strong electrochemical reactions can occur.
  • a crimp contact is provided for the connection.
  • a crimp contact can be formed as a crimp cable lug or the like.
  • the crimp contact is made from sheet metal from a base material.
  • the base material can in particular be a copper material or an aluminum material.
  • a copper material can be understood to be a copper alloy or pure copper, and an aluminum material can be understood to mean an aluminum alloy up to AL99.9 aluminum.
  • the crimp contact is deformed along its joining zone in such a way that the stranded conductor is crimped in a form-fitting manner with the crimp contact in the joining zone.
  • the joining zone is reshaped and pressed against the stranded conductor so that at least a form fit results.
  • the stranded conductor is intermetallically connected to the coating in the joining zone, in particular welded and / or soldered.
  • the second coating runs over the transition between the first coating and the base material. A transition between the coating of the joining zone and the base material is thus protected by the second coating.
  • the coating of the joining zone is applied to the base material, in particular by means of roll cladding or stir-rubbing.
  • Other goal-fulfilling processes such as laser deposition welding, are also possible.
  • friction stir welding or laser deposition welding are useful methods for applying the coating.
  • a crimp contact which is known per se, is connected to a conductor.
  • the crimp contact has the coated joining zone into which the conductor is inserted in a first step.
  • Excitation with a high-frequency oscillation during crimping can improve both the mechanical and the electrical properties of the connection. Melting the coating after the crimping has taken place is also fulfilling the function, e.g. B. Energy / heat input through induction coil.
  • the high-frequency oscillation can break the insulating aluminum oxide layer from the conductor.
  • a first crimp tab with which the stripped end of the conductor is crimped in the receptacle, and a second crimp tab, with which the insulation is crimped.
  • the die and punch are mechanically decoupled from one another in such a way that the high-frequency oscillation of the crimping die and / or crimping punch is not coupled into the die and the punch.
  • the crimp contact 16 is first placed with its joining zone 16a on the crimping die 6.
  • the conductor 18 is then placed with its stripped end 18a onto the joining zone 16a in such a way that the crimping wings 16b protrude beyond the stripped end 18a.
  • the conductor 18 is inserted into the joining zone 16a in such a way that its insulation lies in front of the stripped end 18a in the region of the edge region 16c of the crimp contact 16.
  • the punch 12 and the die 14 are mechanically decoupled from the arrangement of the die 6, booster 8 and converter 10 in such a way that the high-frequency oscillation of the die 6 is not coupled into the die 14.
  • the punch 12 deforms the edge region 16c around the insulation of the conductor 18.
