Definitions

  • Press-in contacts of this type are known and are used to produce solder-free electrical connections which, as so-called press-in connections, can correspond to DIN 41 611, Part 5 (September 1984).
  • the generic press-in contact corresponds to the EE design because the press-in area of its shaft part which forms the actual press-in pin is designed to be elastic, that is to say the forces required for the press-in connection are applied by deforming the elastic shaft part and the printed circuit board receiving the press-in contact. - See section 3.2.2 of DIN 41 611, part 5 -.
  • the contacting in the circuit board hole is improved compared to press-in contacts with a solid press-in pin or shaft part, for example in accordance with the EM design in accordance with DIN 41 611, part 5, section 3.2.1.
  • the object of the innovation is to improve the contacting of the known press-in contacts in the pressed-in state and to counteract excessive deformation of the limbs delimiting the slot opening.
  • this object is achieved in that the slot opening has a parabolic design at its ends, while it has a constriction in the middle due to the widening of the legs.
  • the shaft part tapers approximately linearly from the middle of its length to the connecting pin to half its maximum width and the remaining length of the shaft part between the connecting pin and the end of the slot opening facing it is a fraction of half the length of the shaft part corresponds.
  • the ratio of the remaining length of the shaft part to half the length of the shaft part is in a range between 0.45: 1 and 0.35: 1, preferably 0.4: 1.
  • this new design of the press-in contact can be achieved in that the slot opening in the shaft part is correspondingly extended in the direction of the connecting pin while maintaining its spatial shape.
  • the distance of the slot opening in the shaft part from the press-in shoulder can be 0.34 mm amount, while the length of the slot opening corresponds to 2.78 mm.
  • the remaining length of the shaft part thus remains 0.88 mm, which is a ratio of 0.44: 1 to half the length of the shaft part.
  • press-in contacts according to the invention are particularly suitable for use with printed circuit boards with a nominal thickness of 3.2 mm, but that they can also be used in conjunction with printed circuit boards of smaller nominal thickness, for example 2.4 and 1, 6 mm.
  • a connecting pin 5 is connected to the shaft part 2, a part of which is also only hinted at.
  • the press-in shoulder 3 serves the purpose of limiting the press-in path of the shaft part 2 into a plated-through hole 6 of a printed circuit board 7, the upper side of the printed circuit board 7 and the hole 6 being only indicated by dash-dotted lines.
  • the shaft part 2 is provided with a slot opening 8, the ends 9 and 10 of which each have a parabolic design, while their center has a constriction 11.
  • the end 9 of the slot opening facing the contact spring or the contact pin 4 almost reaches the press-in shoulder 3 and is therefore only a short distance 12 from the latter.
  • the other end 10 of the slot opening 8 lies at a certain distance 13 from the transition between the shaft part 2 and the connecting pin 5. It can also be seen in the drawing that the shaft part 2 extends from the middle of its length to the connecting pin 5, that is to say above the length region 14 tapers from its maximum width 15 to a dimension 16 which corresponds to approximately half of the maximum width 15.
  • the length 17 of the slot opening 8 is limited between the two distances 12 and 13.
  • the middle shaft part 2 of the press-in contact 1 has legs 18 and 19 on each side of the slot opening 8.
  • the total length 20 of the middle shaft part 2 corresponds to the length 17 of the slot opening 8 plus the two distances 12 and 13.
  • the slot opening 8 has a position in the central shaft part 2 such that the remaining length of the shaft part 2 corresponding to the distance 13 is in a ratio to the length range 14 corresponding to half the length thereof, which is between 0.45: 1 and 0.35: 1 and is preferably about 0.4: 1.
  • the remaining length of the shaft part 2 corresponding to the distance 13 is in a ratio of, for example, 0.314: 1 to the length 17 of the slot opening 8 and the distance 12 to the length 17 of the slot opening 8 is in a ratio of, for example, 0, 12: 1.
  • the press-in contact 1 is designed according to the drawing so that the length 17 of the slot opening 8 is in a ratio of about 0.7: 1 to the total length 20 of the central shaft part 2.
  • the width of the slot opening 8 in the region of the constriction 11 to the greatest width thereof in the region of the parabolic ends 9 and 10 has a ratio of approximately 0.73: 1 to 0.74: 1.
