Definitions

  • the invention relates to the contacting of light metal cables, in particular lightweight metal seats, such as aluminum strands, which supply electrical consumers with electrical energy, especially in motor vehicles. Likewise, such light metal cables are used for the grounding of electrical systems. Moreover, the invention relates to a method for producing such a connecting element.
  • the US 3,656,092 describes for this purpose by way of example an aluminum conduit on which an aluminum sleeve with graduated inner diameter is placed so that the leading end of the aluminum conduit abuts the gradation within the aluminum sleeve.
  • a contact element is turned up, which has at least on its side facing the wire a sleeve with complementary inner diameter. The connection of aluminum sleeve and copper contact element is then carried out by welding the two components.

  • the US 2,806,215 also describes the electrical connection of an aluminum line with a contact element made, for example, of copper. Also in this case, a sleeve made of aluminum with graduated inner diameter is pushed onto the contact-side leading end of the aluminum line and then welded to a complementary shaped and ending in a contact plate copper sleeve.
  • a cold welding of an aluminum wire with a pushed onto the leading end of the wire copper sleeve is also exemplified in the DE 19 908 031 A1 as well as the DE 29 903 301 Ul described.

  • connection between metal sleeve and contact element is preferably carried out by cold welding, but can also be realized via the application of an electrically conductive and curable, preferably thermally curable liquid, such as an adhesive or a solder. It can thereby be achieved a positive and non-positive, preferably also cohesive connection.

In addition, such a positive and frictional connection is to be determined even with multicore cables among the others with each other.
  • Such an adhesion is given in particular by the adhesion of the joining partners as a result of abrasions of the surface irregularities.
  • the positive connection is also made by undercuts the light metal line and in particular of stranded wires with folds within the sleeve, these wrinkles especially due to the compression of the metal sleeve during the cold welding operation.
  • a positive connection is also based on the peel stress by the support effect of the sleeve, which is not expected in a direct cold welding a light metal line with a contact element.
  • the cold flow in light metals by both sliding of grains to each other, but in particular by a migration of dislocations and thereby caused repeated abrogation oppositely oriented dislocations even at room temperature and leads to a reduction of mechanical stresses in the metal structure and thus also to a Reduction of the strength of the material.
  • the joining partners are subjected to frictional energy up to the plastic state, as a result of which the stress occurring during pressing is largely reduced.
  • a preferably electrically conductive and curable liquid for example a solder, whereby preferably a heat input into the material takes place, via which the energy required for the migration of dislocations is introduced into the material.
  • the connecting element according to the invention should also allow good protection against corrosion, in particular with respect to electrochemical corrosion. This protection is particularly important at two points of the connecting element according to the invention of particular importance, namely at the end or contact element end of the welded line and at the line end of the metal sleeve with the incoming here light metal wires.
  • the exposed light metal wires can not be easily protected with a coating, such as tin, from corrosion, since the oxide layer present on the surface prevents complete wetting with the conductive liquid.

  • the dimensions of the metal sleeve are adjusted so that it protrudes beyond the line end after being pushed onto the usually stripped end of the light metal, so that after the cold welding process, this front end of the metal sleeve is substantially pressed against each other.
  • a flat surface is formed, which advantageously supports the connection of the sleeve with the contact element, usually a flat contact or connection lug.
  • the front edge of the pressed metal sleeve is designed so that it is almost gap-free, whereby the preferred gas-tightness after the Applying the curable liquid can be achieved more easily. Preference is also given to a procedure when applying the liquid, which allows the liquid covering this remaining gap in the sleeve gap and preferably closes gas-tight.

  • the light metal lead is an aluminum lead, which is most preferably an aluminum strand of a plurality of wires. In such strands, the individual wires of the line are usually arranged around a core parallel to each other and spirally wound.
  • the metal sleeve can generally be made of any material which is connectable to a light metal via a cold welding.
  • a metal sleeve made of copper in particular electrolytic copper and very particularly preferably soft-annealed electrolytic copper. This can be achieved in particular in conjunction with an aluminum line, a particularly good cold welding result.
  • electrolytes electrically conductive media
  • connection of the metal sleeve to the contact element takes place in the sense of the invention for example via a cold welding or via an electrically conductive and curable liquid.
  • a cold welding is preferred or if a soldering with a shape adapted to the shape of the contact element metal sleeve can be done.

  • the cold welding between metal sleeve and light metal line and optionally between the metal sleeve and contact element can be advantageously supported by the shape of the joining partners and in particular by a coordinated form of the mutually facing joining surfaces of the joining partners.
  • the cold welding, in particular the ultrasonic cold welding advantageous supported when the joining surfaces of the joining partners are designed substantially complementary to each other. This also facilitates the placement of the metal sleeve on the sleeve-side end of the light metal line and, where appropriate, their centering within the metal sleeve, or the placement of the usually squeezed contact element end of the cold-welded to the light metal metal shell on the connecting lug of the contact element.
  • an embodiment of the invention is considered to be particularly advantageous in which it is made possible that at least partial areas of the metal sleeve are formed into the cross section of the light metal conduit during the cold-welding operation. This can be done in a particularly simple and preferred manner in that the inner diameter of the metal shell to a certain extent of preferably 5 to 30%, and particularly preferably 10 to 20%, greater than the outer diameter of the stripped light metal line.
  • a method for producing a connecting element for the electrical Connection between a light metal line and an electrical contact made available in which in a first step, the cold welding of a metal sleeve takes place with the light metal line and in a subsequent step, the connection of the metal sleeve is made with a contact element on the finally the contact of the light metal line with the electric Consumer, in particular in a motor vehicle, is produced.
  • the connection of the metal sleeve and contact element takes place for example via cold welding or by the application and the curing of an electrically conductive liquid, for example an adhesive or solder.

  • the ultrasonic frequency is generated by means of a high-frequency generator, this frequency being converted via an ultrasonic transducer into mechanical vibrations, which are transmitted to the sonotrode.
  • no plasticization of one or both interfaces of the joining partners is produced; Rather, as already described, the connection takes place after the oxide layer has broken open, essentially by a meshing of the respective joining partners.
