Abstract

A contact carrier for an electrical contact device comprises a contact carrier body and a contact element disposed in the contact carrier body. The contact carrier body has a connecting section and a conductor clamping section. The conductor clamping section is substantially closed in a circumferential direction of the contact carrier body and extends along a longitudinal direction of the contact carrier body. The contact element has a contact section extending from the connecting section for contacting a mating contact element.

First claim

What is claimed is:

1. A contact carrier for an electrical contact device, comprising:
a contact carrier body having a connecting section and a conductor clamping section, the conductor clamping section substantially closed in a circumferential direction of the contact carrier body and extending along a longitudinal direction of the contact carrier body, the conductor clamping section has a top wall on a side of a contact chamber, the top wall having an integral hinge extending in the longitudinal direction of the contract carrier body and is deformable along the integral hinge in the longitudinal direction and into the contact chamber, the top wall including a predetermined breaking point extending in the longitudinal direction of the contract carrier body or a through-slot extending in the longitudinal direction of the contact carrier body for deformable displacement of the top wall; and
a contact element disposed in the contact carrier body, the contact element having a contact section extending from the connecting section for contacting a mating contact element.

2. The contact carrier of claim 1 , wherein a longitudinal end section of a conductor of a cable is clamped onto a cable contact section of the contact element by deformation of the contact chamber.

3. The contact carrier of claim 2 , wherein the top wall of the conductor clamping section is deformable to clamp the longitudinal end section of the conductor directly or indirectly onto the cable contact section.

4. The contact carrier of claim 3 , wherein the predetermined breaking point or the through-slot is disposed at a center of the top wall and the top wall has a pair of deformable wings on opposite sides of the predetermined breaking point or through-slot.

5. The contact carrier of claim 3 , wherein the predetermined breaking point or the through-slot is disposed on a lateral end of the top wall and the top wall is formed as an individual deformable wing.

6. The contact carrier of claim 1 , wherein the top wall is displaced at the predetermined breaking point or directly adjacent to the through-slot into the contact chamber in response to the deformation of the top wall in the longitudinal direction along the integral hinge.

7. An electrical contact unit, comprising:
a shield contact device having a contact carrier receptacle and a conductor crimping section; and
a contact carrier disposed in the contact carrier receptacle and having a conductor clamping section deformable by crimping of the conductor crimping section, the conductor clamping section has a top wall on a side of a contact chamber, the top wall having a first side facing the contact chamber and a second side opposite the first side, the top wall having an integral hinge extending in the longitudinal direction of the contract carrier and being deformable along the integral hinge in the longitudinal direction and into the contact chamber by an inwardly facing projection of a crimp terminal of the conductor crimping section contacting the second side of the top wall in a direction of the contact chamber during crimping.

8. The electrical contact unit of claim 7 , wherein the contact carrier insulates a longitudinal end section of a conductor of a cable from the shield contact device.

9. The electrical contact unit of claim 7 , wherein a longitudinal end section of a conductor of a cable is clamped onto a cable contact section of a contact element disposed in the contact carrier by the conductor clamping section.

10. The electrical contact unit of claim 9 , wherein the conductor is an inner conductor of the cable.

11. The electrical contact unit of claim 7 , wherein the longitudinal end section of the conductor is clamped onto the cable contact section by the top wall when the top wall is deformed.

12. The electrical contact unit of claim 7 , wherein the inwardly facing projection is formed at the crimp terminal during crimping.

13. A method of producing an electrical cable assembly, comprising:
providing a shield contact device having a contact carrier receptacle and a contact carrier having a contact element, the contact carrier disposed in the contact carrier receptacle and having a conductor clamping section deformable by crimping, the conductor clamping section has a top wall on a side of a contact chamber, the top wall having an integral hinge extending in a longitudinal direction of the contact carrier and is deformable along the integral hinge in the longitudinal direction and into the contact chamber; and
crimping a conductor crimping section of the shield contact device onto a surface of the top wall of the conductor clamping section opposite the contact chamber to establish an electrically conductive and mechanically fixed connection between a cable contact section of the contact element and a longitudinal end section of an electrical conductor of a cable.

14. The method of claim 13 , wherein the longitudinal end section of the conductor is clamped onto the cable contact section by the top wall of the conductor clamping section.

15. The method of claim 14 , wherein the longitudinal end section of the conductor and the cable contact section are insulated from the shield contact device.

16. An electrical cable assembly, comprising:
a cable;
a shield contact device having a contact carrier receptacle and a conductor crimping section; and
a contact carrier disposed in the contact carrier receptacle and having a conductor clamping section deformable by crimping of the conductor crimping section and clamping a conductor of the cable onto a cable contact section of a contact element disposed in the contact carrier, the conductor clamping section has a top wall on a side of a contact chamber, the top wall having an integral hinge extending in a longitudinal direction of the conductor of the cable such that a free end of the top wall extending in the longitudinal direction of the conductor of the cable is deformable along the integral hinge in the longitudinal direction and into the contact chamber.

17. The electrical cable assembly of claim 16 , wherein the top wall comprises a first side facing the contact chamber and a second side opposite the first side, the top wall being deformable into the contact chamber by the conductor crimping section acting on the second side of the top wall in a direction of the contact chamber.
