  • Publication number: 20160372881
    Abstract: The present invention relates to a method for connecting an electrical conductor (12) to an electrical contact part (14), which has a base part (16) and deformable flanks (18) connected thereto, wherein the flanks (18) are deformed by means of a device, which has a bending punch (26) and a resting region (24) for at least one section of the base part (16) of the electrical contact part (14), by means of the bending punch (26) in such a way that said flanks (18) compress the electrical conductor (12) with the contact part (14) in a force-fitting manner, wherein, at least within a lower dead center time period of the bending punch (26), the contact part (14), which is arranged at least partially between the resting region (24) and the bending punch (26), is acted upon through the resting region (24) in such a way that at least one component (20) of the electrical conductor (12) is cohesively connected to the base part (16) and/or at least one flank (18).

  • Patent number: 9325135
    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.
