Abstract

A connection device for connecting a shield conductor of an electrical cable to a grounding section includes: a housing surrounding a receiving space into which an electrical cable is insertable with a shield conductor along a longitudinal axis, the housing being attachable to the grounding section such that the grounding section extends at least partly in the receiving space; and a spring element which is adjustably disposed on the housing and which has a clamping leg and is movable from an open position to a clamped position relative to the housing such that when in the clamped position, the spring element acts with the clamping leg on the shield conductor of the electrical cable inserted in the receiving space, the clamping leg having an engagement portion for acting on the shield conductor, the engagement portion having an at least partially curved or angled engagement contour.

First claim

The invention claimed is:

1. A connection device for connecting a shield conductor of an electrical cable to a grounding section, the connection device comprising:
a housing surrounding a receiving space into which an electrical cable is insertable with a shield conductor along a longitudinal axis, the housing being attachable to the grounding section such that the grounding section extends at least partly in the receiving space; and
a spring element which is adjustably disposed on the housing and which has a clamping leg and is movable from an open position to a clamped position relative to the housing such that when in the clamped position, the spring element is configured to act with the clamping leg on the shield conductor of the electrical cable inserted in the receiving space, the clamping leg having an engagement portion configured to act on the shield conductor, the engagement portion having an at least partially curved or angled engagement contour at a side facing the shield conductor as viewed in a plane perpendicular to the longitudinal axis.

2. The connection device as recited in claim 1 ,
wherein the spring element is pivotable about a pivot axis relative to the housing.

3. The connection device as recited in claim 1 ,
wherein the connection device is configured to hold the shield conductor of the electrical cable in the clamped position between the spring element and the grounding section.

4. The connection device as recited in claim 1 ,
wherein the engagement portion has a first contact portion and a second contact portion, which form the engagement contour.

5. The connection device as recited in claim 4 ,
wherein the first contact portion and the second contact portion are separated from each other by a slit.

6. The connection device as recited in claim 4 ,
wherein the first contact portion and the second contact portion are angled relative to each other when viewed in the plane perpendicular to the longitudinal axis.

7. The connection device as recited in claim 4 ,
wherein the clamping leg has at least a third contact portion disposed between the first contact portion and the second contact portion.

8. The connection device as recited in claim 7 ,
wherein the third contact portion is separated by slits from the first contact portion and the second contact portion.

9. The connection device as recited in claim 7 ,
wherein the third contact portion is angled relative to both the first contact portion and the second contact portion as viewed in the plane perpendicular to the longitudinal axis.

10. The connection device as recited in claim 1 ,
wherein the spring element has an actuating leg that is pivotably supported on the housing and bent over relative to the clamping leg.

11. The connection device as recited in claim 10 ,
wherein the clamping leg is curved about the pivot axis in a region of the engagement portion.

12. The connection device as recited in claim 10 ,
wherein the actuating leg has a latching device configured to provide a latching connection to the housing in the clamped position.

13. The connection device as recited in claim 10 ,
wherein the actuating leg has at least one hinge lug projecting therefrom via which the actuating leg is pivotably connected to the housing.

14. The connection device as recited in claim 10 ,
wherein the actuating leg has at least one latching nose on an end portion remote from the clamping leg configured to provide latching engagement with at least one latching projection of the housing in the clamped position.

15. The connection device as recited in claim 14 ,
wherein the end portion of the actuating leg is provided with a tool engagement aperture for releasing configured to release the spring element from the clamped position.

16. The connection device as recited in claim 1 ,
wherein the housing has two side walls extending parallel to each other and spaced apart along a transverse direction and a base connecting the side walls, the receiving space being formed between the side walls.

17. The connection device as recited in claim 16 ,
wherein the shield conductor of the electrical cable is insertable into the housing such that the shield conductor extends along the longitudinal axis through the receiving space between the side walls.

18. The connection device as recited in claim 16 ,
wherein the shield conductor of the electrical cable is insertable into the receiving space in an insertion direction transverse to the longitudinal axis and transverse to the transverse direction.

19. The connection device as recited in claim 16 ,
wherein the housing is attachable to the grounding section such that the grounding section extends through the receiving space along the transverse direction.

20. The connection device as recited in claim 16 ,
wherein the side walls have recesses configured to receive the grounding section.

21. An assembly comprising an electrical cable having a shield conductor, a grounding section, and a connection device;
wherein the connection device comprising a housing surrounding a receiving space into which an electrical cable is insertable with a shield conductor along a longitudinal axis, the housing being attachable to the grounding section in such a way that the grounding section extends at least partly in the receiving space, and
a spring element which is adjustably disposed on the housing and which has a clamping leg and is movable from an open position to a clamped position relative to the housing such that when in the clamped position, the spring element is configure to act with the clamping leg on the shield conductor of the electrical cable inserted in the receiving space, the clamping leg having an engagement portion configured to act on the shield conductor, the engagement portion having an at least partially curved or angled engagement contour at a side facing the shield conductor as viewed in a plane perpendicular to the longitudinal axis.

22. The assembly as recited in claim 21 ,
wherein the grounding section is part of a mounting rail or a busbar.
