Definitions

  • press-in contacts are described in EP-A-0 731 526 and EP-A-0 141 492 have become known and are used to produce solderless electrical connections that as a so-called press-fit connection can comply with DIN 41611, Part 5.
  • the generic press-in contact corresponds to the EE type because the Press-in region of its shaft part forming the actual press-in pin is elastic is formed, that is, by the forces necessary for the press-in connection Deformation of the elastic shaft part and that of the press-in contact PCB are applied - see section 3.2.2 of DIN 41611, part 5 -.
  • a press-in contact is known from German utility model G 90 04 090.2, in which the contact in a sleeve of a printed circuit board in the pressed state compared to other well-known press contacts is improved by the slit opening has the same parabolic shape at both ends, while constricting in the middle. This makes one too strong, unequal deformation of the legs delimiting the slot opening counteracted so that it does not straighten after a press-in process Need to become.
  • the invention has for its object to a generic press-in contact create, in which there is excessive hole wall deformation of the circuit board sleeve can be avoided.
  • An advantageous embodiment of the invention provides for the elasticity of the shaft part to be increased even further by the legs delimiting the slot opening on their Outside have an embossing that extends from the press-in shoulder to Extend the area of the pin.
  • the experiments have shown that despite the increased elasticity of the press-in contact the requirements for Minimum holding force of 20 N according to IEC 352-5 must be exceeded.
  • Tests confirmed that even after a thermal load of 500 h at 105 ° C. there is still a reliable electrical connection, which is indicated by a stable Contact resistance and the unchanged high holding forces can be recognized.
  • press-in contacts according to the invention due to their good elasticity can have a significantly shorter overall length and thus Particularly suitable for printed circuit boards with a nominal thickness of 1.6 mm.
  • a press-in contact 1 shown in FIG. 1 for pressing into a plated-through hole Hole in a printed circuit board has a central shaft part 2, to which the left over a press-in shoulder 3 connects a contact spring 4. To the front right end the shaft part 2 goes into a conical, tapering forward, one Pin 5 receiving head 17 over.
  • the shaft part 2 is with a conical slot opening 7 reaching into the area of the contact spring 4 provided, the upper and lower and front ends 8, 9 each have a has parabolic training.
  • the end 9 facing the contact spring 4 and having a parabolic design comprehensive part 10 of the conical slot opening 7 is formed wider than that other, front part 11, which has a waist 12 approximately in the middle of the slot opening 7 has, then slightly expanded again and then towards pin 5 rejuvenated.
  • the parabolic end 9 of the slot opening facing the contact spring 4 extends into the contact spring 4 and is thus after a press-in process outside the circuit board.
  • the other, narrower end 8 of the slot opening 7 is located on the other hand in the circuit board and ends at a distance 13 in the transition between the shaft part 2 and the connecting pin 5.
  • the outer jacket of the press-in contact 1 has the slot opening 7 on both sides in the middle shaft part 2 each have a leg 14 and 15; these have a convex External shape and are each along their length between the press-in shoulder 3 and Area of the connecting pin 5 with a running out above the head piece 17 Embossing 16 provided. Due to the design and location of the slot opening 7 and the leg 14 and 15 with their stamping 16 becomes the entire press-in contact 1 more elastic, which on the one hand leads to the contact becoming nonetheless at the same time high holding forces can be pressed in with reduced force and on the other hand one Hole wall deformation can be reduced. Nevertheless, there is still a good one Contact between the middle shaft part 2 and the plated-through hole 6 in the circuit board.
