Abstract

The subject-matter of the invention is an electrical device comprising:a casing comprising a cavity receiving an electrical component, andat least two conductors connected to the electrical component so as to supply it with electric energy, both conductors being superimposed with each other and extending in parallel,said device being characterised in that it comprises an electric insulating film folded on itself around a fold, and a first part of which located on a side of the fold comes against a surface of the first conductor so as to electrically insulate it, and a second part of which located on the other side of the fold is inserted between both conductors so as to electrically insulate them from each other.

First claim

What is claimed is:

1. An electrical device comprising:
a casing comprising a cavity receiving an electrical component, and
at least two conductors connected to the electrical component so as to supply it with electric energy, both conductors being superimposed with each other and extending in parallel,
wherein said electrical device comprises an electric insulating film folded on itself around a fold, a first part of the electric insulating film being located on a side of the fold and coming against a surface of the first conductor so as to electrically insulate it from a housing, and a second part of the electric insulating film being located on the opposite side of the fold and being inserted between both conductors so as to electrically insulate them from each other, the second part of the electric insulating film coming against another surface of the first conductor opposite to the surface of the first conductor receiving the first part of the electric insulating film.

2. The electrical device according to claim 1 , wherein the fold of the electric insulating film comprises at least one aperture adapted to allow free access to the conductors.

3. The electrical device according to claim 1 , wherein the first part and the second part of the electric insulating film each have at least one protrusion inserted into the cavity of the casing and embedded in a filling material of the cavity of the casing.

4. The electrical device according to claim 1 , forming a capacitive block, and wherein the electrical component is a capacitive element.

5. The electrical device according to claim 1 , wherein the first part is held on the surface of the first conductor through an adhesive material.

6. The electrical device according to claim 1 , wherein the electric insulating film is made of plastic.

7. An electrical equipment comprising a housing and the electrical device according to claim 1 housed in said housing, the first part of the electric insulating film electrically insulating the first conductor from other components of the electrical equipment located in said housing of the electrical equipment, the second part of the electric insulating film, insulating the conductors from each other.

8. The electrical device according to claim 2 , wherein the first part and the second part of the insulating film each have at least one protrusion inserted into the cavity of the casing and embedded in a filling material of the cavity of the casing.

9. The electrical device according to claim 2 , forming a capacitive block, and wherein the electrical component is a capacitive element.

10. The electrical device according to claim 3 , forming a capacitive block, and wherein the electrical component is a capacitive element.

11. The electrical device according to claim 3 , wherein the first part of the electric insulating film is folded so as to fit the surface of the first conductor and is held against said surface of the first conductor only through the at least one protrusion and the fold.

12. The electrical device according to claim 2 , wherein the first part is held on the surface of the first conductor through an adhesive material.

13. The electrical device according to claim 3 , wherein the first part is held on the surface of the first conductor through an adhesive material.

14. The electrical device according to claim 4 , wherein the first part is held on the surface of the first conductor through an adhesive material.

15. The electrical device according to claim 2 , wherein the insulating film is made of plastic.

16. The electrical device according to claim 3 , wherein the insulating film is made of plastic.
