Definitions

  • the invention relates to a component according to the preamble of claim 1.
  • These contacts are known to be resistance welded to the contact holder to weld. It is also state of the art to place contacts in a contact holder restenieten. These rivets can be used as a prefabricated rivet or as a wire section available for riveting.
  • the object of the invention is to provide a contact attachment that the previously generated Contact surface not damaged.
  • an optimal electrical Connection arise.
  • the contact holder must not be deformed.
  • Both one-sided and two-sided contacts can be made.
  • a stable one Manufacturing process, especially when integrated into a progressive tool, must be guaranteed.
  • the solution must be particularly suitable for very thin carrier sheets (contact holders) his.
  • the usual contact materials must be usable.
  • Figure 1 shows an example of a spherical contact 1, which is bent downwards by 3 Retaining tab 2 is held. The one bent up on the opposite side Welding flaps 3 are used in this case for welding the ball 1 to the Carrier tape material 4.
  • the left half of the cut represents the state before welding part 1 to the Welding cloth 3 represents, the right half of the illustration shows the welded state 5, which was generated with the aid of a laser beam, which was represented symbolically (6) has been.
  • the volume of the weld metal can be defined with the height of the welding flap 3 to get an optimal weld 5.
  • the bending angle "alpha" can be selected that the ball 1 snaps into the contact holder during assembly and between rags 2 and 3 are held.
  • Figure 2 shows the blank of the contact holder 4 and one formed by the blank Bore 11, which is used for inserting the contact 1, for what purpose before or during insertion of the contact, the tabs 2, 3 are bent out of the plane of the contact holder Need to become.
  • the bending lines 7 on which the tabs are shown are shown symbolically be turned.
  • tabs 2 and 3 are arranged alternately and offer with three up and down Rags an optimal hold of the contact 1. Versions with two rags 2 and 3 are also conceivable.
  • the number and arrangement of the lobes also depends on the contact shape. For example using a cylindrical contact 1b (not shown) is the arrangement the rag accordingly.
  • FIG. 3 shows an example of a spherical contact 1, which in this case is one-sided is held down in the contact holder by holding tab 2, and in the spaces partially stamped at three points by two stamps 8a and 8b at point 9 is so that the contact 1 overlaps the contact holder 4 in the region of these deformations 9 and hereby defines non-positively and positively.
  • the decisive factor here is the fact that only short areas 9 of the contact holder 4 are affected by the imprint.
  • the contact holder 4 remains deformation-free, the reveal remains low.
  • the contact surface 10 of the contact 1 remains unaffected and is therefore not damaged.
  • contact 1 of both is recommended Emboss sides symmetrically against the top and bottom of the contact holder 4.
  • Figure 4 shows the cut of the contact holder 4 with the bore 11 and the bending lines 7.
  • the spherical contact 1 is shown in dashed lines schematically with the embossing areas 9 shown. In this example, three embossing areas are shown over the circumference.
  • Figures 5 and 6 show a similar solution variant as Figures 3 and 4, see above that the same components are provided with the same reference numerals. Only the holding tabs 2 are omitted in the design according to Figures 5 and 6, whereby the Contact 1 is not set in contact holder 4 before embossing.
  • the cutting of the The contact holder accordingly has one (corresponding to the cross section of the contact 1) circular hole 11 on.
  • the advantage of the invention is that the contact in the contact holder is very simple can be assembled. Both the positioning and the fixation of the contact is ensured.
  • the electrical connection can be made by welding or stamping in the Area of mutual overlap are generated, thereby ensuring can ensure that the carrier material is not deformed and the contact surface is not damaged becomes.
