Abstract

A disk-shaped insulator contains a conductive block and an insulating body, wherein the conductive block is located in a central region of the disk-shaped insulator. The radial dimensions of the insulating body are adapted to those of a flange used for connecting. Multiple holes are distributed over an edge region of the disk-shaped insulator, and the edge region is covered by a conductive coating.

First claim

The invention claimed is:

1. A disk-shaped insulator, comprising:
a central region;
a conductive block disposed in said central region of the disk-shaped insulator;
an insulating body having radial dimensions adapted to those of a flange to be connected to;
an edge region having multiple holes formed therein and distributed over said edge region of the disk-shaped insulator, said edge region having sides including an upper side, a lower side and a connecting side connecting said upper side to said lower side; and
a conductive coating covering said upper side, said lower side and said connecting side of said edge region and having characteristics of a layer having been directly coated onto said edge region.

2. The disk-shaped insulator according to claim 1 , wherein said insulating body has at least three reinforcing pieces distributed uniformly along said edge region and protrude in radial directions, each of said reinforcing pieces having an opening formed therein, and the disk-shaped insulator is connected to the flange by means of the openings.

3. The disk-shaped insulator according to claim 2 , wherein each of said holes and said openings in said insulating body is defined by a cylinder surrounded by resin.

4. The disk-shaped insulator according to claim 3 , wherein said cylinder is made of metal.

5. The disk-shaped insulator according to claim 1 , wherein said insulator body is made of resin.

6. The disk-shaped insulator according to claim 1 , wherein said insulating body having a groove formed therein and disposed adjoining said edge region.

7. The disk-shaped insulator according to claim 1 , further comprising a transition region disposed between said central region and said edge region, said insulating body having a groove formed therein disposed between said transition region and said edge region.

8. The disk-shaped insulator according to claim 1 , further comprising hollow metal cylinders disposed in said insulating body and defining said holes in said insulating body, said hollow metal cylinders extending completely through said insulating body.
