  • Patent number: 10283924
    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: 9077135
    Abstract: The present invention relates to a machine for delivering supplied hollow bushes and for fitting individual hollow bushes to a cable, and to a corresponding method. The apparatus has a picking apparatus which can pick up hollow bushes and arrange said hollow bushes so as to be axially aligned in front of the fitting tube, and a bush fitting apparatus for fitting individual hollow bushes to a cable, wherein the bush fitting apparatus has a fitting tube which can receive and hold, on the outer surface of said tube, the hollow bushes on the inner surface thereof, and in which the cable for fitting the hollow bushes can be arranged.
