Abstract

A spacer to hold an electrical cable is provided. The spacer includes a first clamp segment, a second clamp segment, and a hinge connecting the first clamp segment and the second clamp segment and permitting relative movement between the first clamp segment and the second clamp segment from an open position, wherein the first clamp segment and the second clamp segment do not hold the electrical cable, to a closed position, wherein the first clamp segment and the second clamp segment hold the electrical cable. The spacer also includes a corona shield extending from the first clamp segment to the second clamp segment and covering the hinge when the first clamp segment and the second clamp segment are in the open position and when the first clamp segment and the second clamp segment are in the closed position.

First claim

What is claimed is:

1 . A spacer to hold an electrical cable, comprising:
a first clamp segment; a second clamp segment; a hinge connecting the first clamp segment and the second clamp segment and permitting relative movement between the first clamp segment and the second clamp segment from an open position, wherein the first clamp segment and the second clamp segment do not hold the electrical cable, to a closed position, wherein the first clamp segment and the second clamp segment hold the electrical cable; and a corona shield having a first end and a second end, and extending from the first end, at the first clamp segment, to the second end, at the second clamp segment, and covering the hinge when the first clamp segment and the second clamp segment are in the open position and when the first clamp segment and the second clamp segment are in the closed position, wherein the corona shield is flexible to flex during the relative movement between the first clamp segment and the second clamp segment.

2 . The spacer as set forth in claim 1 , wherein:
the first clamp segment has a hemispherical outer surface, the second clamp segment has a hemispherical outer surface, and the corona shield has a hemispherical inner surface that conforms to the hemispherical outer surface of the first clamp segment and the hemispherical outer surface of the second clamp segment.

3 . The spacer as set forth in claim 1 , wherein the corona shield comprises a corona discharge resistant material.

4 . The spacer as set forth in claim 1 , wherein the corona shield comprises an elastomeric material.

5 . The spacer as set forth in claim 1 , wherein the corona shield comprises rubber.

6 . The spacer as set forth in claim 1 , comprising a retention member that retains the corona shield to at least one of the first clamp segment or the second clamp segment.

7 . The spacer as set forth in claim 1 , comprising a first retention member that retains the corona shield to the first clamp segment and a second retention member that retains the corona shield to the second clamp segment.

8 . The spacer as set forth in claim 1 , comprising a first resilient member fastened to the first clamp segment, wherein the first resilient member grips the electrical cable to hold the electrical cable when the first clamp segment and the second clamp segment are in the closed position.

9 . The spacer as set forth in claim 8 , comprising a first fastener that fastens the first resilient member to the first clamp segment.

10 . The spacer as set forth in claim 9 , wherein the first clamp segment defines a first through-hole and the first fastener extends from the first resilient member through the first through-hole to fasten the first resilient member to the first clamp segment.

11 . The spacer as set forth in claim 10 , wherein the first fastener functions as a first retention member to retain the corona shield to the first clamp segment.

12 . The spacer as set forth in claim 11 , wherein the corona shield defines an opening and the first fastener extends through the opening to retain the corona shield to the first clamp segment.

13 . A spacer to hold an electrical cable, comprising:
a first portion comprising an arm segment, an end segment, and a first clamp segment, the end segment and the first clamp segment located at opposite ends of the arm segment, the end segment constructed for attachment to a structure from which the electrical cable is supported; a second portion comprising a second clamp segment; a connection connecting the first portion and the second portion and permitting relative movement between the first portion and the second portion from an open position, wherein the first clamp segment and the second clamp segment do not hold the electrical cable, to a closed position, wherein the first clamp segment and the second clamp segment hold the electrical cable; and a corona shield extending from the first clamp segment to the second clamp segment and covering the connection when the first portion and the second portion are in the open position and when the first portion and the second portion are in the closed position, wherein the corona shield is configured to move with the first clamp segment and the second clamp segment during the relative movement between the first clamp segment and the second clamp segment.

14 . The spacer as set forth in claim 13 , wherein:
the first clamp segment has a hemispherical outer surface, the second clamp segment has a hemispherical outer surface, and the corona shield has a hemispherical inner surface that conforms to the hemispherical outer surface of the first clamp segment and the hemispherical outer surface of the second clamp segment.

15 . The spacer as set forth in claim 13 , wherein the corona shield comprises a polymer.

16 . The spacer as set forth in claim 13 , comprising a first retention member that retains the corona shield to the first clamp segment and a second retention member that retains the corona shield to the second clamp segment.

17 . The spacer as set forth in claim 16 , comprising:
a first resilient member; and a first fastener that fastens the first resilient member to the first clamp segment, wherein the first resilient member grips the electrical cable to hold the electrical cable when the first portion and the second portion are in the closed position.

18 . The spacer as set forth in claim 17 , wherein the first clamp segment defines a first through-hole and the first fastener extends from the first resilient member through the first through-hole to fasten the first resilient member to the first clamp segment.

19 . A spacer to hold an electrical cable, comprising:
a first portion comprising an arm segment, an end segment, a first clamp segment, and a first resilient member, the end segment and the first clamp segment located at opposite ends of the arm segment, the end segment constructed for attachment to a structure from which the electrical cable is supported, the first resilient member fastened to an inner surface of the first clamp segment; a second portion comprising a second clamp segment and a second resilient member fastened to an inner surface of the second clamp segment; a connection connecting the first portion and the second portion and permitting relative movement between the first portion and the second portion from an open position, wherein the first resilient member and the second resilient member do not hold the electrical cable, to a closed position, wherein the first resilient member and the second resilient member hold the electrical cable; and a flexible corona shield extending from the first clamp segment to the second clamp segment and covering the first portion, the second portion and the connection when the first portion and the second portion are in the open position and when the first portion and the second portion are in the closed position.

20 . The spacer as set forth in claim 19 , comprising a first retention member that retains the corona shield to the first clamp segment and a second retention member that retains the corona shield to the second clamp segment.
