Definitions

  • the invention relates to an electrical contact element for Fastening and contacting in metallized holes, for example in a printed circuit board, with a Press-in area for pressing into the hole, the one formed between two contact legs needle-like Has elongated hole, and with a connection area that itself via a transition area to the press-in area adjoined.
  • EP 731 526 A2 describes a pin-shaped contact element with the features of the preamble of claim 1 known.
  • a pin-shaped contact element for contact fastening in metallized perforations from electrical circuit boards proposed, which in essentially from an elongated hole Press-in area and an adjoining one Connection area exists.
  • An electrical contact element is known from US Pat. No. 5,374,204 for fastening and contacting in metallized Bores, for example a circuit board, known with a press-in area for pressing into the bore, the has a slot-shaped slot, and with a connection area that extends over a Transition area connects to the press-in area.
  • the Press-fit area is made up of two layers of sheet metal formed, each one between two contact legs have arranged needle-like elongated hole and the symmetrical to the plane between the layers on top of each other are arranged. To increase the rigidity of the layers have a stiffening rib above the elongated hole on. It is an object of the invention an electrical Specify contact element that in the connection area thin material used and easy to manufacture can.
  • a such a solution can also be used for an electrical contact element with a press-in area and a connection area be aimed for if the connection area consists of a should be made significantly thinner material than it makes sense for the press-fit area. If you put that Press-fit area consisting of two superimposed flat layers with one each between two contact legs needle hole-like elongated hole forth, it results the problem that when inserting the press-in area in a hole the superimposed layers apart bulge. The force intended for contacting, which is normally achieved by squeezing the Contact leg arises, is therefore not sufficient applied and poor contact made becomes.
  • the two layers of sheet metal are symmetrical arranged one on top of the other and each have a curvature.
  • the two layers are arranged such that in one Cross section, viewed perpendicular to the direction of insertion outer edges of the two layers spaced apart are arranged while the centers touch.
  • This press-fit area into a bore will now be the contact leg of each layer moved towards each other and thus narrowed the elongated hole.
  • the double layer does not have an elastic effect impaired, but is rather supported. A good Contacting is guaranteed.
  • FIG 1 is an electrical according to the invention Contact element shown.
  • the electrical contact element has a press-fit area 2, a transition area 3 and an adjoining connection area 4.
  • the press-in area 2 consists of two layers 5, 6 (see FIG 2) a metal sheet is formed.
  • Each of the layers 5, 6 has an elongated hole 7, 8 formed like a needle eye (see FIG 6) on.
  • the slot 7, 8 is between two Contact legs 9 to 12 formed.
  • the two layers 5, 6 are folded onto each other. They are symmetrical about the plane E arranged between the two layers.
  • the individual layers 5, 6 in the area of Elongated holes 7, 8 arched. You are like that arranged to each other so that they are in the middle area touch and the outer edges 109 to 112 from each other are arched away and therefore diverge.
  • Figures 7 and 8 the effect of Press-fit area 2 in a metallized bore 13 shown.
  • Figure 7 shows the section as already Figure 3 is known in an unloaded position the bore 13.
  • the elongated holes 7 and 8 have their maximum unloaded width.
  • the contact legs are 9 to 12 elastic. Will there be pressure on the Press-fit area in the direction of the bore, see above the contact legs of a layer move 9 and 10 or 11 and 12 towards each other, reduce the clear width of slot 7 or 8 and penetrate into the Hole in. Due to the elastic deformation a Contacting force applied to the corresponding Contacting the edge 109 to 112 of the contact leg 9 up to 12 with the metallization of the elongated hole guaranteed.
  • transition area 3 and Connection area 4 with reference to Figures 1, 2, 4, 5 and 6 described.
  • the Connection area 4 essentially round in cross section is formed with two contact arms 14 and 15.
  • the contact arms are for contacting a round one Contact pin trained. They are at one end each connected to a base 16 which is already part of the Transition area 3 is.
  • the press-in area 2 is also connected to a corresponding base 17, which here is also essentially round. to Stiffening of the electrical contact element in the
  • the area in which the carrier strip is provided is one corresponding embossing or bulge 18 is provided.
  • the arrangement of the carrier strip 19 is shown in FIGS. 2, 5 and 6 can be seen particularly clearly.
