Abstract

An insert for a conductor clamp has a body portion for applying a clamping force to a conductor. The insert includes an insert body receivable by the body portion of the conductor clamp. The insert body has a first surface adapted to face a portion of the conductor. The insert body is made from a non-metallic and electrically non-conductive material. An adhesive is applied to at least a portion of the first surface of the insert body. A friction enhancing material applied to at least a portion of the adhesive.

First claim

What is claimed is:

1. A conductor clamp for exerting a clamping force to a conductor, the conductor clamp comprising:
a body portion defining a first aperture and a second aperture, the second aperture spaced a first distance from the first aperture;
an insert connectable with the body portion of the conductor clamp, the insert extending along a plane and having:
a first surface parallel to the plane and facing a portion of the conductor,
a second surface parallel to the plane and facing the body portion of the conductor clamp,
a top surface, which is planar and non-parallel to the plane, extending between the first surface and the second surface, and
a bottom surface, which is planar and non-parallel to the plane, extending between the first surface and the second surface, the top surface parallel to the bottom surface, the insert comprising:
a non-metallic and electrically non-conductive material;
a first retaining structure projecting from the second surface in a direction that is perpendicular to the plane; and
a second retaining structure projecting from the second surface in the direction that is perpendicular to the plane, the second retaining structure spaced a second distance from the first retaining structure, the second distance equal to the first distance, the first retaining structure received within the first aperture and the second retaining structure received within the second aperture when the insert is connected to the body portion;

an adhesive applied to at least a portion of the first surface; and
a friction enhancing material applied to at least a portion of the adhesive.

2. The conductor clamp of claim 1 wherein the insert is made from a nylon material.

3. The conductor clamp of claim 1 wherein the friction enhancing material is made from a second electrically non-conductive material.

4. The conductor clamp of claim 1 wherein the electrically non-conductive material is made from a grit particle.

5. The conductor clamp of claim 4 wherein the grit particle is made from crushed glass.

6. The conductor clamp of claim 4 wherein the grit particle is made from a ceramic particle.

7. The conductor clamp of claim 4 wherein the grit particle is made of glass.

8. The conductor clamp of claim 4 wherein the grit particle is made of aluminum oxide.

9. The conductor clamp of claim 1 further including at least one retaining edge on the insert for retaining the insert within the body portion of the conductor clamp.

10. The conductor clamp of claim 9 wherein the body portion extends for a length greater than a length that a retaining edge extends.

11. The conductor clamp of claim 1 , wherein the first retaining structure has a non-circular cross-sectional shape.

12. The conductor clamp of claim 1 , wherein the first retaining structure comprises one or more side features that project in a second direction non-parallel to the direction.

13. The conductor clamp of claim 1 further including a protective material covering at least a portion of the friction enhancing material and adhesive.

14. The conductor clamp of claim 1 further including a second insert attachable to a clamping portion of the body portion to be located on a side of the conductor opposite the insert, the second insert constructed substantially the same as the insert.
