Definitions

  • the present invention relates to a method for connecting a plug to a stranded cable according to claim 1.
  • the most common way to connect a plug to a stranded cable is to crimp a plug that serves as a crimp barrel, the stranded wire, or the flexible litz wire cable.
  • Object of the present invention is therefore to provide a method for connecting a plug with a Litzentent that ensures a high joint strength, a low contact resistance and the gentlest possible production of the compound and in particular regardless of the cross section of the stranded cable applicable.
  • the invention is based on the idea to create a positive and cohesive connection after compaction of the stranded cable between the stranded cable and the plug receiving the stranded cable, in particular different metals of the flexible stranded cable (copper, aluminum or similar conductive material) on one side and the metal present at least in the connecting portion of the plug are provided.
  • a compaction or precompacting of the stripped end portion of the stranded cable leads to a reduction of the required energy and an improvement of the particularly intimate, positive and cohesive connection between the stranded cable and the plug.
  • the interior of the stranded cable, ie the heddle core is compacted by the precompacting. As a result, the consumption of additional energy in the production of the positive or cohesive connection is avoided.
  • the invention also provides a helium-tight and / or gas-tight connection.
  • the preparation of the compound comprises a, in particular radial, pressurization, which is suitable for producing a positive and cohesive connection
  • the connection in particular without welding, and thus particularly independent of the cross section, in particular for larger cross sections (> 20 mm 2 cross-sectional area ) be used.
  • magnet forming in particular by means of electromagnetic pulse technology, that is, an electrodynamic Hochenergyumformungs vide.
  • electrodynamic Hochenergyformungs vide in particular cold forming of the electrically conductive materials or sections of the stranded cable and the plug, namely the stripped end section of the stranded cable and of the metallic connection section of the plug, takes place.
  • the advantage of the magnetic forming consists in a very precise adjustability of the pressure or pressing forces and a very homogeneous distribution of forces on the circumference, so that the radial pressurization after joining the, in particular sleeve-shaped, metallic connecting portion of the connector with the end portion of the stranded cable particularly homogeneous on Scope can be distributed.
  • the magnetic field for the magnetic deformation through substances such as glass, ceramic and plastic act through, so that an application under vacuum to avoid oxidation and thus with better material consistency is feasible.
  • a protective gas atmosphere or clean room conditions are also conceivable.
  • magnet forming offers very high repeatability and extremely short process life and independence from thermal processes.
  • the method according to the invention initially consists of precompacting / compacting the stripped end section of the stranded cable, which consists in particular of a plurality of copper strands.
  • the magnetic forming takes place to produce a positive and cohesive connection between the connecting section and the end section.
  • the stranded cable will strip exactly the length corresponding to the insertion depth of the end section into the connecting section of the plug.
  • the particularly intimate cohesive connection in particular by covalent bonds between the materials of the stranded cable on one side and the connector on the other side leads to a high joint strength, in particular the strength of the softer material of the stranded cable / plug accordingly.
  • the inventive method also prevents damage to nearby components after joining the plug with the stranded cable, since no welding is provided after the joining.
