Abstract

An electrical crimp contact that crimps onto an electrical cable has a conductor crimp region for an electrical connection of a conductor of the cable, the conductor crimp region having a fixing device for fixing the conductor. In a blank of the contact, the fixing device of the conductor crimp region extends at an oblique angle with respect to a longitudinal axis of the contact.

First claim

What is claimed is:

1. An electrical crimp contact, comprising:
a conductor crimp region having a pair of crimp flanks, each crimp flank disposed on an opposite side of a connection base;
a conductor fixing device extending at an oblique angle from a longitudinal axis of the crimp contact and disposed continuously in the pair of crimp flanks and the connection base in a transverse direction of the crimp contact; and
an insulation crimp region having an insulation fixing device including a first insulation fixing zone formed as at least one recess and a second insulation fixing zone formed as at least one projection.

2. The electrical crimp contact of claim 1 , wherein the conductor fixing device is constructed in an arrowhead or v-shape in the conductor crimp region, in such a manner that the tip of the arrowhead or v-shape points in the direction of the insulation crimp region.

3. The electrical crimp contact of claim 1 , wherein the oblique angle of the conductor fixing device with respect to the longitudinal axis of the contact is greater than 0° and less than 90°.

4. The electrical crimp contact of claim 3 , wherein the oblique angle of the conductor fixing device is greater than or equal to 45° and less than or equal to 89°.

5. The electrical crimp contact of claim 4 , wherein the oblique angle of the conductor fixing device is greater than or equal to 70° and less than or equal to 89°.

6. The electrical crimp contact of claim 1 , wherein the conductor fixing device comprises a first conductor fixing zone and a second conductor fixing zone, one or both conductor fixing zones extending at an oblique angle with respect to the longitudinal axis.

7. The electrical crimp contact of claim 6 , wherein the first conductor fixing zone is formed in a mirror image of the second conductor fixing zone along the longitudinal axis of the contact.

8. The electrical crimp contact of claim 1 , wherein the conductor fixing device is a 3D structure having at least one of a rib, a groove, a groove structure, a ripple structure, a corrugated structure, and a serration.

9. The electrical crimp contact of claim 1 , wherein the insulation crimp region mechanically clamps an insulation of a cable and the insulation fixing device additionally mechanically secures the cable.

10. The electrical crimp contact of claim 9 , wherein the first insulation fixing zone has at least one of a rib, groove, groove structure, ripple structure, corrugated structure, and serration, and the second insulation fixing zone has at least one of a cam, claw, hook, knob-like structure, needle structure, and hook structure.

11. The electrical crimp contact of claim 1 , wherein the insulation fixing zones are separated distinctly from each other in the insulation crimp region, the first insulation fixing zone located adjacent to the second insulation fixing zone.

12. The electrical crimp contact of claim 1 , further comprising a reinforcement stamping at least partially overlapping the conductor crimp region.

13. A preassembled electrical cable, comprising:
an electrical crimp contact crimped to an electrical cable;
the electrical crimp contact having a conductor crimp region having a pair of crimp flanks, each crimp flank disposed on an opposite side of a connection base, a conductor fixing device extending at an oblique angle from a longitudinal axis of the crimp contact and disposed continuously in the pair of crimp flanks and the connection base in a transverse direction of the crimp contact, and an insulation crimp region having an insulation fixing device including a first insulation fixing zone formed as at least one recess and a second insulation fixing zone formed as at least one projection.

14. A blank of an electrical crimp contact, comprising:
a conductor crimp region having a crimp flank;
a conductor fixing device disposed in the crimp flank and extending at an oblique angle from a longitudinal axis of the blank in a plane of the crimp flank, the oblique angle configured such that the oblique angle becomes perpendicular to the longitudinal axis of the blank in the plane of the crimp flank after crimping; and
an insulation crimp region having an insulation fixing device including a first insulation fixing zone formed as at least one recess and a second insulation fixing zone formed as at least one projection.

15. The blank of claim 14 , wherein the conductor fixing device is interrupted by a web of the conductor crimp region in a transverse direction of the contact.

16. The blank of claim 15 , wherein the conductor fixing device comprises a first conductor fixing zone and a second conductor fixing zone, one or both conductor fixing zones extending at an oblique angle with respect to the longitudinal axis.

17. The blank of claim 16 , wherein the first conductor fixing zone is formed in a mirror image of the second conductor fixing zone along the longitudinal axis of the contact.

18. The blank of claim 17 , wherein the web of the conductor crimp region is provided in the transverse direction between the first conductor fixing zone and the second conductor fixing zone, the web constituting a complete thickness of a material layer of the conductor crimp region.

19. The blank of claim 14 , wherein the oblique angle of the conductor fixing device is greater than or equal to 45° and less than or equal to 89°.

20. The electrical crimp contact of claim 11 , wherein the first insulation fixing zone has a plurality of recesses disposed along the transverse direction of the crimp contact and the second insulation fixing zone has a plurality of projections disposed along the transverse direction of the crimp contact.

21. The electrical crimp contact of claim 20 , wherein the plurality of recesses of the first insulation zone are mirrored about the longitudinal axis of the crimp contact and the plurality of projections are mirrored about the longitudinal axis of the crimp contact.
