Abstract

The invention relates to a method for electrically connecting a conductor to a contact, according to which the electrical conductor that is coated with an insulation is first inserted between two legs of the contact, whereupon a welding device is placed against both legs and the welding process is carried out by turning on the welding current. The insulation of the electrical conductor is destroyed due to the heat delivered during the welding process, resulting in a permanent mechanical and electrical connection between the conductor and the contact.

Claims

1. A method for the electrical connection of an electrical conductor to a contact element with the following steps:

introduction of the electrical conductor ensheathed with an insulation between two legs of the contact element,

application of a welding device to both legs, conducting the welding process by switching on the welding current, whereby the heat introduced during the welding process breaks down the insulation of the electrical conductor and leads to a solid mechanical and electrical connection of the conductor with the contact element.

2. The method according to claim 1, further characterized in that the welding process is a resistance welding.

3. The method according to claim 2, further characterized in that at the beginning of the welding process, the welding current flows over the two legs of the contact element and its connection point.

4. The method according to claim 1, further characterized in that the welding device is applied to the outer sides of the two legs lying opposite the conductor.

5. The method according to claim 4, further characterized in that a welding stamp of the welding device is applied in each case to one outer side of contact element.

6. The method according to claim 1, further characterized in that the contact element is connected to a plug connector.

7. The method according to claim 1, further characterized in that the conductor ensheathed with an insulation is a flat flex conductor.

8. The method according to claim 1, further characterized in that the contact element is bent in an S-shape.

9. The method according to one of claims 1, further characterized in that the contact element is bent in a C-shape.

10. A plug connector with a contact element and an electrical conductor, which is connected to the contact element, is hereby characterized in that the connection between contact element and electrical conductor was produced according to a method according to claim 1.
