Definitions

  • the invention relates to a press-fit contact produced as a turned part for establishing an electrical connection, for example in a plated-through hole of a printed circuit board, for plug-in connections or else as an attachment point for a soldered connection.
  • the invention is based on the object of improving press-fit contacts of said type in such a way that an even bearing pressure and even contact-making are ensured over the entire contact zone.
  • the invention comprises that the pressing-in zone is shaped in the form of a barrel in its outer contour, is designed cylindrically hollow on the inside and is provided with a plurality of axially parallel longitudinal slits.
  • the press-fit contact 1 may be provided in its upper region with a peripheral cross-sectional widening 3 with supporting shoulders 2 and at the upper end with an attachment stub 4, for example for producing a soldered contact, a contact pin or a contact spring.
  • the press-fit contact 1 is, according to the invention, shaped in the form of a barrel in its outer contour 8 and turned or drilled out hollow-cylindrically in the inner region 9.
  • the barrel-formed contour is interrupted by a plurality of, for example four, axially parallel longitudinal slits 6.
  • the longitudinal slits 6 preferably do not run over the entire length of the press-in zone 10, but only over a subregion, in such a way that an annular insertion edge 5, which is provided on the outside with an insertion bevel 11, remains at the lower, free end, the insertion region.
  • the contact region 10 is loaded approximately evenly over its entire length in all cross-sectional regions, the greatest diameter region lying in the region of the highest bending moment.
  • the pressing-in of such press-fit contacts is made easier and a substantially even contact-making over the entire press-in zone is achieved.
