Abstract

To connect the shielding of an electric cable to a metallic connector, an electrically non-conductive cable guide part that features a wall segment of an electrically conductive material that needs to be laterally opened sectionally is provided. In this case, the shielding of the electric cable lying in the interior is connected to a corresponding mating connector by means of the wall segment and an electrically conductive connector sleeve surrounding the connector.

Claims

1. A contact element for connecting the shielding of an electric cable to a connector, comprising:

a nonconductive cylindrical cable guide part having a collar and a sectionally openable electrically conductive segment disposed in a recessed semicircular section of the collar for electrically connecting to the shielding of the electric cable.

2. The contact element according to claim 1, further comprising

a toggle lever formed on the electrically conductive segment and insertable into a corresponding opening in the cable guide part, wherein the toggle lever rotatably supports the electrically conductive segment such that the electrically conductive segment can be outwardly opened by being radially tilted about an imaginary axis of rotation.

3. The contact element according to claim 1, wherein

a bevel is provided on the electrically conductive segment on the surface bordering the cable guide part.

4. The contact element according to claim 1, wherein

the cable guide part features ribs that point into the interior in order to fix and contact the shielding of the electric cable, wherein one rib is formed on the cable guide part and at least one other rib is formed on the electrically conductive segment.

5. The contact element according to claim 1, wherein

the electrically conductive segment comprises about half the collar.

6. The contact element according to claim 3, wherein

the bevel allows the electrically conductive segment to be outwardly opened about 30 degrees.

7. The contact element according to claim 1, wherein

the electrically conductive segment and collar of the cable guide part are provided with locking grooves oppositely arranged.

8. The contact element according to claim 1, wherein

the interior of the cable guide part comprises a plurality of through-openings, wherein individual electric conductors of the electric cable may be respectively inserted.

9. A contact element for connecting the shielding of an electric cable to a connector, comprising

an electrically conductive segment of a collar of a cylindrical, non-conductive cable guide part is provided in a recessed section and is openable sectionally,

a toggle lever formed on a wall of the electrically conductive segment and insertable into a corresponding opening in the cable guide part, wherein the toggle lever rotatably supports the electrically conductive segment such that the electrically conductive segment can be outwardly opened by being radially tilted about an imaginary axis of rotation, wherein the toggle lever of the wall of the electrically conductive segment is lockable by a snap-in shoulder formed in the opening of the cable guide part.

10. The contact element according to claim 9, wherein

a bevel is provided on the electrically conductive segment on the surface bordering the cable guide part.

11. The contact element according to claim 9, wherein

the cable guide part features ribs that point into the interior in order to fix and contact the shielding of the electric cable, wherein one rib is formed on the cable guide part and at least one other rib is formed on the electrically conductive segment.

12. The contact element according to claim 9, wherein

the electrically conductive segment comprises about half the collar.

13. The contact element according to claim 10, wherein

the bevel allows the electrically conductive segment to be outwardly opened about 30 degrees.

14. The contact element according to claim 9, wherein

the electrically conductive segment and collar of the cable guide part are provided with locking grooves oppositely arranged.

15. The contact element according to claim 9, wherein

the interior of the cable guide part comprises a plurality of through-openings, wherein individual electric conductors of the electric cable may be respectively inserted.
