Definitions

  • the invention relates to a metallic contact element according to the preamble of patent claim 1.
  • tin in this specification means a tin-containing alloy suitable for electrical contact purposes.
  • the person skilled in the art selects a tin alloy suitable for the desired application from known alloys.
  • chip formation is reliably avoided because the contact element with its front when scraping into the hole does not scrap on the hole wall.
  • the insertion of the contact element is associated with no or less force than in known Einpresstechniken. Damage to the tinned sleeve by the pressing is therefore avoided.
  • the force required to produce the cold-welding takes place by means of a bent leg and if necessary additionally by means of a wedging action. Since no chips occur, the risk of short circuits or shunts is virtually eliminated.
  • the contacting process is also simplified since damage to the tinned sleeve in the printed circuit board by means of the press-fitting of a press-fit geometry is conceptually eliminated.
  • the printed circuit board is significantly less stressed in the contact area. It is to be expected a high contact security with good long-term behavior. Furthermore, in principle, large holding forces are possible because the contacting of the mounting portion forms an undercut after the plastic deformation.
  • tin is preferred.
  • the contact element 1 shown in FIG. 1 is stamped from tinned sheet metal (in the example brass sheet metal) and has an upper contacting section 2, a lower fastening section 3 and two lateral projections 4 therebetween.
  • the Kunststoffierabêt 2 is for example a cross-sectionally approximately rectangular contact pin or a blade contact in the form of a tab.
  • the attachment portion 3 has two downwardly projecting legs 5, 6 with different lengths. Starting from the projections 4, the two legs 5, 6 on their sides facing away from each other down to each other tapered wedge surfaces 7 and then parallel to each other outer surfaces 8, 9.
  • the longer leg 5 protrudes with an end portion 10 on the shorter leg 6, wherein the end portion 10 is hook-shaped bent to the shorter leg 6 and has a downwardly directed tip 11. This tip 11 is arranged eccentrically to the median plane 12 of the longer leg 5 by the amount a.
  • the shorter leg 6 has an oblique end face 13 facing the longer leg 5.
  • the contact element 1 by means of a punch 14, which acts from above on the projections 4, has been inserted into a round hole 15 of a printed circuit board 16, wherein the pointed end portion 10 of the longer leg 5 a Introducer.
  • the attachment portion 3 With the exception of its wedge surfaces 7, the attachment portion 3 has a cross section which is smaller than the diameter of the hole 15 on all sides.
  • the hole 15 is formed by a tinned sleeve 17 which is inserted in the printed circuit board 16. The insertion process is almost powerless, because the legs 5, 6 with the exception of their wedge surfaces 7 without resistance can be inserted into the hole 15.
  • a die 20 (forming tool) is pressed against the end portion 10 by a driving force, as indicated by the arrow 21.
  • the longer leg 5 is bent to the left and partially bent until it finally abuts with its end face (hook surface) 22 against the end face 13 of the shorter leg 6 and this bends to the right and supported.
  • the specially shaped die 20 supports this embossing or forming process.
  • the embossment of the legs 5, 6 caused on the one hand, due to the eccentric load of the longer leg 5 and the specially shaped Gesenkgeometrie, a curling of the longer leg 5, on the other hand thereby the shorter leg 6 is displaced to the outside.
  • Essential for the embossment is the expansion of the two legs 5, 6 in relation to the hole 15.
  • this may also have on its shorter leg 6 side facing a dashed line notch 25 shown in FIG. This notch 25 causes the longer leg 5 bends to the left under pressure load and with its end portion 10, the shorter leg 6 bends to the left.
