Definitions

  • the invention relates to a to be arranged in a chamber of a housing a flat sheet metal stamped electrical contact element in Insulation displacement technique of a cable connector according to the preamble of claim 1.
  • Such an electrical contact element is, for example, from EP-PS 0 416 306 known.
  • This known electrical contact element has one End a pair of double insulation displacement clamps, between which elastic expandable clamping legs an electrical conductor in Insulation displacement technology can be determined.
  • the other end of the Contact element is designed as a pair of fork springs, between the electrical contacting, for example, the contact pin of a plug electrical connector can be inserted.
  • To be safe Contact between the fork spring legs and the inserted To ensure the contact pin of a connector, the fork spring legs contact zones protruding inwards into the insertion slot.
  • the object of the invention is to further develop an electrical contact element in such a way that reliable contacting between the fork spring legs and an inserted contact pin of a plug is always guaranteed.
  • the electrical Contact element are the contact zones of two leaf springs one Fork spring leg offset in the longitudinal direction of the fork spring leg arranged to each other. This additional staggered arrangement of the Contact zones are also used when using the most varied Contact pins secure electrical contact between the Fork spring legs and one inserted into the insertion slot Contact pin guaranteed.
  • Fork spring legs on an inserted contact pin have the Contact zones of two directly opposite leaf springs the same Contact surface shape.
  • the electrical contact element 1 shown in Fig. 1 consists of a one-piece stamped sheet metal part from which the electrical contact element 1 through successive bending operations is bent. From the level Sheet metal stamped part then gives an electrical contact element 1, as shown in Figures 1 to 3 is shown.
  • each of these double insulation displacement pairs 3 consists of two clamping legs 3a, which have an insertion slot between them 3b form for the electrical cable 2.
  • the fork spring pair 5 consists of two Fork spring legs 5a, which have an insertion slot 5b between them Form the contact pin of a connector. 2 and 3, there is each fork spring leg 5a from two separate leaf springs 5c.
  • the Andes Leaf springs 5c are preferably formed by pressing in contact zones 6 are offset in the longitudinal direction of the fork spring leg 5a and formed laterally to the longitudinal center line of the contact element 1, wherein the contact zones 6 of the leaf springs 5c of a fork spring leg 5a have differently configured contact surfaces 6a.
  • the offset arrangement of the contact zones 6 causes that in completely the insertion slot 5b inserted flat knife connector 4, as shown in Fig. 3, the contact zones 6 of the fork spring legs 5a are not in the Area of a locking hole 4a of the flat blade connector 4 for contact with the Flat knife connector 4 come, which results in an insufficient electrical Contact could result.
  • this embodiment shown in Fig. 3 is easy to see that the contact zones 6 with their contact surfaces 6a in some distance to the locking hole 4a of the flat blade connector 4 on the Fit flat knife connector 4.
