Abstract

The present invention relates to an electric contact element that has at least one crimping strap which is configured and arranged to reach around the outer circumference of an electric conductor, at least in sections, at least in a fully crimped state of the contact element. Furthermore, the invention relates to an electric contact arrangement that has at least one electric conductor and at least one contact element that has at least one crimping strap which is crimped, at least in sections, around an outer circumference of the conductor. Finally, the invention relates to a method of producing an electric contact arrangement, at least one crimping strap of a contact element being crimped, at least in sections, around an electric conductor. In order to seal an interior of the contact arrangement as simply and effectively as possible and with long-term stability against the penetration of corrosive media, provision is made according to the invention such that at least one front protection strap of the contact element is aligned running, at least in sections, transversely to the at least one crimping strap and rests against the latter, a front section of the electric conductor being covered, at least in sections, by the at least one front protection strap.

First claim

What is claimed:

1. An electric contact element adapted for assembly with an electrical conductor, said electric contact element comprising:
a first crimping strap and a second crimping strap each configured and arranged to reach around at least partially the outside of the electric conductor extending substantially transverse to the crimping straps when in a fully crimped state of the contact element; and
a first protection strap and a second protection strap each extending substantially transverse to the crimping straps and configured and arranged to cover and rest against at least partially the crimping straps and cover an end of the conductor when the crimping straps are in a fully crimped state of the contact element, the first protection strap and the second protection strap overlapping in a longitudinal direction of the contact element in the fully crimped state.

2. The electric contact element according to claim 1 , wherein the protection straps are configured and arranged to rest against the contact element in the fully crimped state.

3. The electric contact element according to claim 2 , wherein the first protection strap is formed integrally with the first crimping strap and extends away from the first crimping strap.

4. The electrical contact element according to claim 1 , wherein the two protection straps are disposed substantially opposite one another in related to a center axis of the contact element.

5. The electric contact element according to claim 1 , wherein a free end of each of the protection straps has a chamfer.

6. An electric contact assembly comprising:
an electric conductor; and
an electrical contact element having:
a first crimping strap and a second crimping strap each reaching around at least partially the outside of the electric conductor extending substantially transverse to the crimping straps when in a fully crimped state of the contact element; and
a first protection strap and a second protection strap extending substantially transverse to the crimping straps and covering and resting against at least partially the crimping straps and covering an end of the electric conductor when the crimping straps are in a fully crimped state of the contact element, the first protection strap and the second protection strap overlapping in a longitudinal direction of the contact element in the fully crimped state.

7. The electric contact assembly according to claim 6 , wherein the protection straps are individually formed integrally with the crimping straps and extend away from the respective crimping straps.

8. The electric contact assembly according to claim 6 , wherein the two protection straps are disposed substantially opposite one another in relation to a center axis of the contact element.

9. The electric contact assembly according to claim 6 , wherein a free end of each of the protection straps has a chamfer.

10. The electric contact element according to claim 1 , wherein the protection strap is bent substantially at a right angle in the fully crimped state.

11. The electric contact assembly according to claim 6 , wherein the protection strap is bent substantially at a right angle in the fully crimped state.

12. A method of producing an electric contact assembly, comprising:
crimping a first crimping strap and a second crimping strap around at least partially the outside of an electric conductor extending substantially transverse to the crimping straps; and
covering an end of the electric conductor when the crimping straps are in a fully crimped state with a first protection strap and a second protection strap, the first protection strap and the second protection strap extending substantially transverse to the crimping straps, covering and resting against at least a part of the crimping straps, and overlapping in a longitudinal direction of the electric conductor in the fully crimped state.
