Abstract

In a method for connecting an electrical conductor to an electrical contact part, wherein the contact part has deformable legs the legs are deformed by means of a bending die in such a way that the legs press the conductor with the contact part in a force-locked manner, wherein the contact part is acted upon in so that at least the legs are materially connected to each other. A device includes a bending die for connecting an electrical conductor to an electrical contact part, wherein the contact part has deformable legs and the bending die is designed to deform the legs in such a way that the legs press the conductor with the contact part in a force-locked manner, and wherein the device also includes a laser welding device designed to act on the contact part so that at least the legs are materially connected to each other.

First claim

The invention claimed is:

1. A device for connecting an electrical conductor to an electrical contact part, comprising:
a bending die having a recess, said recess having a bending side arranged opposite a topside of the bending die, said bending side having adjacent arches curved toward the topside, said bending die having an opening extending between the topside and the bending side;
a plunger having a support surface supporting the electrical contact part, said plunger being receivable in the recess so as to engage legs of the electrical contact part with the bending side of the bending die, wherein engagement of the bending side with the legs of the contact part effects a bending of the legs toward a center of the contact part, thereby causing legs to force fitting engagement of the legs with a conductor situated between the legs; and
a laser welding device arranged relative to the bending die so that a laser beam emitted by the laser welding device is directable through the opening into the recess and onto the contact part so as to effect material connection of at least the legs of the contact part.

2. The device of claim 1 , wherein the opening is arranged in the bending side.

3. The device of claim 1 , further comprising a positioning device, configured to position the laser welding device and/or the contact part so that the welding laser beam emitted by the laser welding device impinges at a site of at least one recess respectively provided on a respective edge of each of the legs.
