Abstract

A cable clamp includes an elongated, open-top base having a first end, a second end, and a central region. A suspension arm extends from the open-top base. An eyelet having an opening, a top portion, and a base portion is coupled to the suspension arm. The eyelet base portion has a first width and the top portion has a second width greater than the first width. A keeper is coupled to the base.

Claims

1. A cable clamp comprising:

an elongated, open-top base having a first end, a second end, and a central region;

a suspension arm extending from said open-top base; and

an eyelet having an opening, a top portion, and a base portion coupled to said suspension arm, said base portion having a first width and said top portion having a second width greater than said first width.

2. The cable clamp of claim 1, further comprising a keeper coupled to said base.

3. The cable clamp of claim 1, wherein said suspension arm comprises a first wall and a second wall angled relative to said first wall.

4. The cable clamp of claim 1, wherein said first end and said second end comprise respective first and second flared openings.

5. The cable clamp of claim 4, wherein said central region comprises a first longitudinal groove and a second longitudinal groove.

6. The cable clamp of claim 1, wherein said eyelet is spatulate.

7. The cable clamp of claim 1, wherein said open-top base, suspension arm, and eyelet are integrally formed.

8. The cable clamp of claim 2, wherein said keeper comprises a semi-obround clamping arm including an arcuate first leg, an arcuate second leg, and a substantially planar central portion extending between said first leg and said second leg.

9. The cable clamp of claim 8, wherein said keeper is coupled to said open-top base via a mechanical fastener.

10. The cable clamp of claim 8, wherein said keeper further comprises an attachment arm extending substantially orthogonal to said clamping arm.

11. The cable clamp of claim 10, 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.

12. The cable clamp of claim 11, further comprising a tab extending from said open-top base having a slot alignable with said opening in said keeper attachment arm.

13. The cable clamp of claim 8, wherein said open-top 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.

14. The cable clamp of claim 13, wherein said base comprises a suspension arm and said first recess is positioned in said suspension arm.

15. The cable clamp of claim 14, wherein said base comprises a center channel and said first and second recesses are elevated from said center channel.

16. The cable clamp of claim 15, wherein said keeper is spaced from said center channel when coupled to said base to define an opening to secure a ribbon cable.

17. A cable clamp comprising:

an elongated, open-top base having a first end, a second end, a central region, a suspension arm, a first recess, and a second recess;

an eyelet having a base and a top portion connected to said suspension arm, said base having a first width and said top portion having a second width greater than said first width; and

a keeper coupled to said open-top base, the 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 leg is received in said first recess and said second leg is received in said second recess.

18. The cable clamp of claim 17, wherein said first end and said second end are flared and said central region comprises a first longitudinal groove and a second longitudinal groove.

19. The cable clamp of claim 17, wherein said suspension arm comprises a first wall and a second wall angled relative to said first wall.

20. The cable clamp of claim 17, wherein said keeper further comprises an attachment arm extending substantially orthogonal to said clamping arm having 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.
