  • the metallic body which consists in particular of solid metal, may for example have a cuboid or a cylindrical shape. But in principle it can also have a polygonal shape.
  • the contact elements in the form of the contact pins and the Einpressköntaktele- elements are arranged in the sense of high stability and optimum current conductivity in particular as evenly distributed as possible on the underside of the metallic body.

On its one side facing a printed circuit board 200 (FIGS. 4 to 6), the metallic body 100 has contact elements 110, 120. On its other side facing away from the printed circuit board 200, a connecting element for an electrical conductor is arranged, which according to the invention is designed as a crimp sleeve 140, which is also referred to below as a crimp tube.
  • the crimp tube 140 is driven into the metallic body 100 during manufacture of the high current contact element and held in the body 100 by interference fit.
  • the crimp tube can have a smooth surface or knurling in the area of the press fit. Knurling has the advantage that in this way tolerance fluctuations can be compensated for and a secure hold in the body 100 after the press fit is ensured.

  • a further embodiment of a high-current contact element according to the invention differs from the high-current contact element described above in connection with FIGS. 1 to 6 in that the crimp tube 140 is not fixed in the metallic body 100 by press fit, but instead is integrally connected to the metallic body 100.
  • the crimping tube 140 is thus manufactured in a manufacturing step together with the metallic body 100.
  • the high-current contact element illustrated in FIGS. 7 to 9 moreover has only press-fit contact elements 110 with a flexible press-fit zone, in contrast to the high-current contact element described above in connection with FIGS. 1 to 6.
