Abstract

An earthing contact for creating an electrical contact between an earthing cable and a component comprising an electroconductive component surface, comprises an electroconductive contact plate and a fixing element, the contact plate having a first contact surface for placing the contact plate on the component surface, a second contact surface for placing an earthing cable on the contact plate, and a passage for the fixing element, the fixing element comprising a fixing section for fixing the fixing element in the component, a pressure element for pressing the contact plate onto the component surface and a holding section for arranging in the passage of the contact plate, when the pressure element presses the contact plate onto the component surface, the first contact surface being tiltable in relation to the fixing section by a tilting angle of at least 6° when the holding section is arranged in the passage.

First claim

The invention claimed is:

1. A ground contact for making electrical contact between a ground cable and a component with an electrically conductive component surface, comprising an electrically conductive contact plate and a fastening element, wherein the contact plate has a first contact surface for applying the contact plate to the electrically conductive component surface, a second contact surface for applying a ground cable to the electrically conductive contact plate and a passage for the fastening element, wherein the fastening element has a fastening section for fastening the fastening element to the electrically conductive component, a pressure element for pressing the electrically conductive contact plate to the electrically conductive component surface and a holding section for arranging in the passage of the electrically conductive contact plate when the pressure element presses the electrically conductive contact plate to the electrically conductive component surface, wherein the first contact surface is tiltable with respect to the fastening section by a tilt angle of at least 6°, when the holding section is arranged in the passage.

2. The ground contact according to claim 1 , also having a gasket which is arranged between the pressure element and the electrically conductive contact plate.

3. The ground contact according to claim 1 , wherein the fastening element has a fixing section for fixing the ground cable to the second contact surface.

4. The ground contact according to claim 1 , wherein the first contact surface is tiltable with respect to the fastening section by a tilt angle of at least 10°.

5. The ground contact according to claim 4 , wherein the first contact surface is tiltable with respect to the fastening section by a tilt angle of at least 20°.

6. The ground contact according to claim 1 , wherein the pressure element is rigidly connected to the holding section.

7. The ground contact according to claim 6 , wherein the pressure element is configured as a stop shoulder on the holding section.

8. The ground contact according to claim 1 , wherein the fastening section is configured as a bolt section for driving into a borehole of the component.

9. The ground contact according to claim 8 , wherein the bolt section has a self-forming thread for screwing into the borehole.

10. The ground contact according to claim 1 , wherein the passage is configured as a circular cylindrical bore with a bore diameter and a bore length, and the holding section is configured as a circular cylindrical shaft section with a shaft diameter.

11. The ground contact according to claim 10 , wherein a ratio of a difference between the bore diameter and the shaft diameter on the one hand, and the bore length on the other hand, amounts to at least 0.05.

12. The ground contact according to claim 11 , wherein the ratio of the difference between the bore diameter and the shaft diameter on the one hand, and the bore length on the other hand, amounts to at least 0.1.

13. The ground contact according to claim 12 , wherein the ratio of the difference between the bore diameter and the shaft diameter on the one hand, and the bore length on the other hand, amounts to at least 0.2.

14. The ground contact according to claim 1 , wherein the holding section is connected rigidly to the fastening section.

15. The ground contact according to claim 14 , wherein the first contact surface is connected rigidly with the passage.

16. The ground contact according to claim 14 , wherein the first contact surface is tiltable with respect to the fastening section by a tilt angle of at least 10°.

17. The ground contact according to claim 14 , wherein the passage is configured as a circular cylindrical bore with a bore diameter and a bore length, and the holding section is configured as a circular cylindrical shaft section with a shaft diameter.

18. The ground contact according to claim 1 , wherein the first contact surface is connected rigidly with the passage.

19. The ground contact according to claim 18 , wherein the first contact surface is tiltable with respect to the fastening section by a tilt angle of at least 10°.

20. The ground contact according to claim 18 , wherein the passage is configured as a circular cylindrical bore with a bore diameter and a bore length, and the holding section is configured as a circular cylindrical shaft section with a shaft diameter.
