Abstract

A cable clamp includes a base and a keeper. The base has a first end, a second end, and a center channel. The keeper is coupled to the base and has a semi-obround clamping arm including an arcuate first leg, an arcuate second leg, and a central portion extending between said first leg and said second leg.

Claims

1. A cable clamp comprising:

an open top, elongated base having a first end, a second end, a center channel, a first sidewall, and a second sidewall, the base defining an elongated axis; and

a keeper coupled to said base, said keeper having a clamping arm with a semi-obround cross section taken through a plane orthogonal to the elongated axis and including an arcuate first leg extending parallel to the elongated axis, an arcuate second leg extending parallel to the elongated axis, and a planar central portion extending between said first leg and said second leg;

wherein said base comprises a first recess for receiving said first leg of the keeper and a second recess for receiving said second leg of the keeper; and

a suspension arm extending from said base and wherein said first recess is located in said suspension arm.

2. The cable clamp of claim 1, wherein said keeper is coupled to said base via a mechanical fastener.

3. The cable clamp of claim 1, wherein said keeper further comprises an attachment arm extending substantially orthogonal to said clamping arm.

4. The cable clamp of claim 3, wherein said attachment arm comprises an opening for receiving a mechanical fastener, a first protrusion proximate said opening, and a second protrusion proximate said opening, wherein said first and second protrusions are peened to retain a mechanical fastener in said opening.

5. The cable clamp of claim 4, further comprising a tab extending from said base having a slot alignable with said opening in said keeper attachment arm.

6. A cable clamp comprising:

an open top, elongated base having a first end, a second end, a center channel, a first sidewall, a second sidewall, the base defining an elongated axis;

a suspension arm extending from said first sidewalk;

a first recess formed at least partially in said suspension arm and having a first bottom surface and a first back surface;

a second recess formed at least partially in said second sidewall and having a second bottom surface and a second back surface facing said first back surface;

a keeper adapted to be coupled to said base having a first leg and a second leg, said first leg received in said first recess and said second leg received in said second recess;

wherein the center channel extends between the first and second recess.

7. The cable clamp of claim 6, wherein said keeper has a semi-obround cross-section taken through a plane orthogonal to the elongated axis.

8. The cable clamp of claim 6, wherein said first recess includes a first side surface and a second side surface and said second recess includes a third side surface and a fourth side surface.

9. The cable clamp of claim 6, wherein said first and second recesses are elevated from said center channel.

10. The cable clamp of claim 6, wherein said keeper is spaced from said center channel when coupled to said base to define an opening to secure a ribbon cable.

11. The cable clamp of claim 6, wherein said keeper is coupled to said base via a mechanical fastener.

12. The cable clamp of claim 6, wherein said keeper further comprises a central portion extending between said first leg and said second leg and an attachment arm extending substantially orthogonal to said central portion.

13. The cable clamp of claim 12, wherein said attachment arm comprises an opening for receiving a mechanical fastener, a first protrusion proximate said opening, and a second protrusion proximate said opening, wherein said first and second protrusions are peened to retain a mechanical fastener in said opening.

14. The cable clamp of claim 6, further comprising a tab extending from said base having a slot alignable with said opening in said keeper attachment arm.

15. A cable clamp comprising:

a base having a first end, a second end, a center channel, a first sidewall, and a second sidewall;

a suspension arm extending from the first sidewalk;

a first recess formed at least partially in said suspension arm and having a first bottom surface and a first back surface;

a second recess positioned opposite said first recess having a second bottom surface and a second back surface facing said first back surface;

a keeper coupled to said base, said keeper having a semi-obround clamping arm including an arcuate first leg, an arcuate second leg, and a central portion extending between said first leg and said second leg, wherein said first recess receives said first leg and said second recess receives said second leg;

wherein the center channel extends between the first and second recess.

16. The cable clamp of claim 15, wherein said suspension arm comprises a first wall and a second wall angled relative to the first wall.

17. The cable clamp of claim 15, wherein said keeper further comprises an attachment arm extending substantially orthogonal to said central portion having an opening for receiving a mechanical fastener.

18. The cable clamp of claim 17, further comprising a tab extending from said base having a slot alignable with said opening in said keeper attachment arm.
