  • the insulation displacement contact terminal 2 is slightly modified compared to the embodiment of Figure 1 a). It is clear that the outer edges of the contact fingers 3, which are opposite to the clamping slot 4, are concave towards the clamping slot. Thus, the width of the insulation displacement contact terminal 2 in the region of the contact slot is less than in the region of the inlet slopes 6. In this way, the spring force of the contact fingers 3 can be improved.
  • FIG. 2 a shows a side view of the conductor connection contact 1 from FIG. 1 a). It is once again clear that the connection surface 9 is spaced from the plane of the solder connection surfaces 13a, 13b, which is achieved by the foot regions 14. It can also be seen that the insulation displacement contact connection 2 is located on a plane transverse to the plane of the connection surface 9.

  • the right solder pad 13b is not simply formed from the lower peripheral edge of the foot section 4, but from a surface section extending away from the foot section 4. It can also be seen that the contact fingers 3 of the insulation displacement connection taper conically towards the free end with respect to their width. That is, the material thickness of the contact fingers 3 decreases toward their free end.
  • FIG. 3 shows a front view of the conductor connection contact 1 from FIGS. 1 a and 2 a. It is clear that the contact fingers 3 are formed while leaving an intermediate clamping slot 4 of the sheet material and pass in a curve in a common root area 5. The contact fingers 3 taper towards the free end, wherein the inner edges form an insertion funnel there on an inclined surface 6.
  • the insulation displacement contact terminal 2 is thus formed in the manner of a fork contact to a plugged into the clamping slot 4 wire bridge in the form of a non-insulated, round in cross-section rod, an insulated rigid or flexible electrical conductor or a cross-sectionally round, rectangular or otherwise suitable power rail to clamp.
  • FIG. 4 shows a plan view of the conductor connection contact 1 from FIG. 1 a.

It can be seen that the contact fingers 3 now lie on a common plane which extends transversely to the plane of the connection surface 9 and in the longitudinal direction of the connection surface 9, i. to the plug contact terminal 8 extends. In this way, the extension direction of a wire jumper clamped to the insulation displacement contact 2 lies in the clamping region transversely to the longitudinal direction of the conductor connection contact 1, while the extension direction is aligned with the insulation displacement contact connection 2 in the longitudinal direction of the conductor connection contact 1.
  • connection surface 9 does not necessarily have to be a flat surface, as shown. It may also be a curved surface that merges into adjoining curved or straight foot sections 14.
