Abstract

The invention relates to a cover to enclose a longitudinal section of at least one electrical conductor and prevent the formation of an arc or a flashover. The cover has at least two cover parts made of an electrically insulating material. A first cover part and a second cover part each have at least one passage opening. Each passage opening has an electrical conductor guided through it, so that no gap opening, or only a small gap opening remains between the outside surface of the conductor and a bordering wall of the passage opening. Moreover, the cover has at least one connection location. At this connection location, two of the cover parts that are present lie against one another in a force-fit and/or positive-fit manner and form a nondestructively detachable connection. This ensures accessibility to the protected longitudinal section.

First claim

The invention claimed is:

1. A cover for at least one electrical conductor,
with at least two cover parts made of an electrically insulating material,
wherein a first cover part and a second cover part have at least one passage opening, each to guide through one of the electrical conductors that are present,
wherein no location on the periphery has a gap opening between a bordering wall of the respective passage opening and an outside surface of the respective electrical conductor that is guided through whose dimension is greater than a specified cross sectional profile,
wherein the cover has at least one connection location at which two of the cover parts that are present are detachably connected with one another in a force-fit and/or positive-fit manner without using separate connection elements,
and wherein the cover completely surrounds a section of the at least one conductor when the connection is made between the cover parts; and
wherein the cover has a third cover part having a tubular shape, the third cover part being connected at a first connection location with the first cover part and at a second connection location with the second cover part, the third cover part being elastically deformable and the first cover part and the second cover part are rigid.

2. The cover according to claim 1 ,
wherein that at least one of the cover parts that are present is elastically deformable.

3. The cover according to claim 1 ,
wherein that at every connection location that is present two of the cover parts are directly connected with one another.

4. The cover according to claim 2 ,
wherein that the one of the two cover parts has a ring-shaped connection groove and the respective other cover part has a ring-shaped connection projection that engages into the connection groove when the connection is made between the two cover parts.

5. The cover according to claim 2 ,
wherein that at least one of the two cover parts connected with one another at a connection location is elastically deformable to make and undo the connection.

6. The cover according to claim 2 ,
wherein that when a connection is made between the two cover parts at least one of the two cover parts is elastically deformed, causing it to lie against the respective other cover part with a pretensioning force.

7. The cover according to claim 1 ,
wherein the first cover part and the second cover part are moveable relative to one another along the at least one conductor, at least when the connection is undone at the at least one connection location.

8. The cover according to claim 1 ,
wherein that only the first cover part and the second cover part are present and are connected with one another at a connection location.

9. The cover according to claim 1 ,
wherein that the first cover part and the second cover part are arranged at a distance from one another.

10. The cover according to claim 1 ,
wherein that the third cover part has, on at least one of its two opposite ends, each of which is associated with one of the two connection locations, an annular ring that engages into a connection groove on the first cover part or the second cover part when the connection is made.

11. The cover according to claim 1 ,
wherein that at least one or all cover parts is each made as an integral part out of a uniform material.

12. A process to cover a section of at least one electrical conductor using a cover according to claim 1 , with the following steps:
guiding at least one first conductor through a respective passage opening of the first cover part;
guiding at least one second conductor through a respective passage opening of the second cover part;
creating an electrical connection between the at least one first conductor and the at least one second conductor;
creating a detachable force-fit and/or positive-fit connection of the cover parts that are present at at least one connection location, without using separate connection elements.
