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, a first recess, a second recess, and a central region configured to receive a cable;

a suspension arm extending from said open-top base and having an upper portion;

a keeper coupled to said open-top base having a first leg and a second leg, wherein the first leg is received in the first recess, the second leg is received in the second recess, and the first recess extends into the suspension arm; and

an eyelet having an opening, a top portion, and a base portion extending from said upper portion of said suspension arm, said base portion having a first width defined by an outer edge and said top portion having a second width defined by said outer edge greater than said first width.

2. The cable clamp of claim 1, wherein said suspension arm comprises a first wall and a second wall angled relative to said first wall and extending toward said central region to position said eyelet over said central region.

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

4. The cable clamp of claim 3, wherein said central region comprises a first longitudinal groove and a second longitudinal groove.

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

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

7. The cable clamp of claim 1, 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.

8. The cable clamp of claim 7, wherein said keeper is coupled to said open-top base via a mechanical fastener.

9. The cable clamp of claim 7, wherein said keeper further comprises an attachment arm extending substantially orthogonal to said clamping arm.

10. The cable clamp of claim 9, 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.

11. The cable clamp of claim 10, further comprising a tab extending from said open-top base having a slot alignable with said opening in said keeper attachment arm.

12. The cable clamp of claim 1, wherein said base comprises a center channel and said first and second recesses are elevated from said center channel.

13. The cable clamp of claim 12, wherein said keeper is spaced from said center channel when coupled to said base to define an opening to secure a ribbon cable.

14. 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 positioned in the suspension arm, and a second recess positioned opposite the first recess;

an eyelet having a base and a top portion connected to said suspension arm, said base having a first width defined by an outer edge and said top portion having a second width defined by said outer edge 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.

15. The cable clamp of claim 14, wherein said first end and said second end are flared and said central region comprises a first longitudinal groove and a second longitudinal groove.

16. The cable clamp of claim 14, wherein said suspension arm comprises a first wall and a second wall angled relative to said first wall and extending toward said central region to position said eyelet over said central region.

17. The cable clamp of claim 14, 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.
