Abstract

A grounding clamp includes a plate having a first and second opposite longitudinal edges extending in a first direction, and first and second opposite transverse edges extending perpendicularly to the longitudinal edges in a second direction. First and second cable fastening region extend along the first and second transeverse edges, respectively, and are configured to fasten and electrically contact first and second cables to the plate, respectively. An opening is arranged between the cable fastening regions for inserting a fastener. An arm extends from the first or second longitudinal edge in the second direction so that the arm runs parallel to the first and/or second cable fastening region. A tab extends at a free end of the arm parallel to the first and/or second longitudinal edge and perpendicularly to a plane of the plate in a direction of an underside of the plate.

First claim

What is claimed is:

1. A grounding clamp for fastening and electrically contacting at least two cables to a separate surface, the grounding clamp comprising:
a plate having a first longitudinal edge and a second longitudinal edge opposite the first longitudinal edge, wherein the first and second longitudinal edges extend in a first direction of the plate, and the plate having a first transverse edge and a second transverse edge opposite the first transverse edge, wherein the first and second transverse edges extend perpendicularly to the first and second longitudinal edges in a second direction of the plate;
a first cable fastening region configured to fasten and electrically contact a first cable to the plate, wherein the first cable fastening region extends along the first transverse edge;
a second cable fastening region configured to fasten and electrically contact a second cable to the plate, wherein the second cable fastening region extends along the second transverse edge;
an opening arranged between the first and second cable fastening regions for inserting a fastener;
an arm extending from the first or second longitudinal edge in the second direction so that the arm runs parallel to the first and/or second cable fastening region; and
a tab which extends at a free end of the arm parallel to the first and/or second longitudinal edge and perpendicularly to a plane of the plate in a direction of an underside of the plate.

2. The grounding clamp according to claim 1 , wherein the arm has at least one recess.

3. The grounding clamp according to claim 2 , wherein the recess extends in the second direction at least half of a length of the arm.

4. The grounding clamp according to claim 3 , where the recess extends in the second direction at least ¾ of the length of the arm.

5. The grounding clamp according to claim 3 , where the recess extends in the second direction at least ⅞ of the length of the arm.

6. The grounding clamp according to claim 1 , wherein the arm has a rectangular shape.

7. The grounding clamp according to claim 6 , wherein the tab extends over an entire width of the arm.

8. The grounding clamp according to claim 1 , wherein a depth of the tab is more than ⅛ of a length of the arm.

9. The grounding clamp according to claim 8 , wherein the depth of the tab is more than ¼ of the length of the arm.

10. The grounding clamp according to claim 9 , wherein the depth of the tab is more than half of the length of the arm.

11. The grounding clamp according to claim 1 , wherein the opening is circular.

12. The grounding clamp according to claim 1 , wherein a diameter of the opening corresponds to ⅗ of a width of the arm.

13. The grounding clamp according to claim 1 , wherein the diameter of the opening corresponds to 7/10 of the width of the arm.

14. The grounding clamp according to claim 1 , wherein the diameter of the opening corresponds to ⅘ of the width of the arm.

15. The grounding clamp according to claim 1 , wherein the first and second cable fastening regions extend along an entire extent of the first and second transverse edges, respectively, such that a first one of the at least two cables extends along the entire extent of the first transverse edge and a second one of the at least two cables extends along the entire extent of the second transverse edge.

16. The grounding clamp according to claim 15 , wherein a crimp tab is disposed at each end of the first and second cable fastening regions.

17. The grounding clamp according to claim 1 , wherein a crimp tab is disposed at each end of the first and second cable fastening regions.

18. The grounding clamp according to claim 1 , wherein the first and second cable fastening regions extend along an entire extent of the first and second transverse edges, respectively, and wherein, in a direction of the first and second transverse edges, a center of the first and second cable fastening regions is aligned with a center of the opening.

19. The grounding clamp according to claim 18 , wherein, in a direction of the first and second longitudinal edges, a center of at least one of the first and second longitudinal edges is aligned with a center of the opening.
