Abstract

A method for attaching a contact element comprises steps for providing an electrical conductor with a conductive core and an insulating sheath, for detaching a sheath section of the sheath in an end region of the conductor for displacing the sheath section against the core in such a way that the sheath section protrudes beyond a longitudinal end of the core, and for crimping a contact element to the end region of the conductor in such a way that at least a part of the sheath section is being enclosed between the contact element and the core.

First claim

The invention claimed is:

1. A method for attaching a contact element, comprising the following steps:
providing an electrical conductor with a conductive core and an insulating sheath;
detaching a sheath section of the sheath in an end region of the conductor;
displacing the sheath section against the core in such a way that the sheath section protrudes beyond a longitudinal end of the core;
providing a contact element having a front crimp portion and a core contact region;
crimping the contact element to the end region of the conductor in such a way that the detached sheath section is encompassed by the front crimp portion to define a front side sealing region and the core is crimped to the contact element in the core contact region, and the front crimp portion extends continuously to the core contact region to fully enclose the detached sheath section.

2. The method according to claim 1 , wherein the detaching of the core section is effected through cutting.

3. The method according to claim 1 , wherein the protruding part of the sheath section closes entirely around the longitudinal end of the core during the crimping.

4. The method according to claim 1 , wherein the contact element before the crimping has a sleeve-like section and the end region of the conductor is inserted into the sleeve-like section before the crimping.

5. The method according to claim 1 , wherein the crimp region of the contact element is crimped such that the crimp region encloses the sheath rearward of the core contact region.

6. A conductor arrangement within an electrical conductor with a conductive core and an insulating sheath, and with a contact element,
wherein the core has a longitudinal end in an end region of the conductor,
wherein the contact element comprises a conductor-side sealing region, a contact region and a contact-side sealing region, and wherein the contact element is crimped to the conductor in the end region of the conductor, and
wherein between the contact element and the core, a section of the sheath is arranged which section is detached from the remaining regions of the sheath exposing a portion of the core, the detached sheath section being crimped in the contact-side sealing region, the exposed core portion being crimped in the contact region and the remaining regions of the sheath are crimped in the conductor-side sealing region.

7. The conductor arrangement according to claim 6 , wherein the detached section of the sheath protrudes beyond the longitudinal end of the core.

8. The conductor arrangement according to claim 7 , wherein the protruding part of the sheath section is entirely closed around the longitudinal end of the core.

9. The conductor arrangement according to claim 6 , wherein the conductor arrangement has a contact region, in which contact region an electrical contact exists between the contact element and the core,
wherein the contact arrangement has a contact-side sealing region, which is arranged between the contact region and the longitudinal end of the core,
wherein the detached section of the sheath is arranged in the contact-side sealing region.

10. The conductor arrangement according to claim 9 ,
wherein the conductor arrangement has a conductor side sealing region,
wherein the contact region is arranged between the contact-side sealing region and the conductor-side sealing region,
wherein in the conductor-side sealing region a further section of the sheath is arranged between the contact element and the core.

11. A conductor arrangement according to claim 8 , wherein the contact element comprises a second crimp region and, in a contact region of the electrical conductor, the second crimp region of the contact element at least partly forms the contact region of the conductor arrangement.

12. A conductor arrangement according to claim 11 , wherein the contact element further comprises a first crimp region crimped to the conductor in the end region of the conductor, and wherein the first crimp region and the second crimp region are separate pieces and/or crimping regions which may be crimped individually.

13. A conductor arrangement according to claim to 6 , wherein the core has aluminium.

14. A conductor arrangement according to claim 6 , wherein the sheath has PVC.

15. A conductor arrangement according to claim 6 , wherein the contact element has a copper material.

16. The method according to claim 1 , wherein the detached sheath section extends into a transition section of the terminal and the front crimp portion is crimped to an outer perimeter of the detached sheath section.
