Abstract

The object of the invention is an electrical device comprising:
a housing comprising a cavity receiving an electronic component, and at least one first electrical conductor connected to the electronic component so as to supply it with electric power, said electrical device being characterised in that it comprises a first electrically insulating film being against a surface of the first conductor so as to electrically insulate it, said first insulating film having at least one holding member enabling the first insulating film to be attached to a mechanical element, in particular of the electrical device.

First claim

What is claimed is:

1. An electrical device comprising:
a casing comprising a cavity receiving an electronic component, and at least one first electrical conductor connected to the electronic component so as to supply it with electric power,
wherein said electrical device comprises a first electrically insulating film being against a surface of the first conductor so as to electrically insulate it, said first insulating film having at least one holding member enabling the first insulating film to be attached to a mechanical element, in particular of the electrical device.

2. The electrical device according to claim 1 , comprising a second electrical conductor connected to the electronic component so as to supply it with electric power, the first and second electrical conductors being superimposed with each other and extending along two distinct parallel planes, and wherein the mechanical element is a second insulating film positioned between the conductors so as to insulate the first and the second conductor from each other.

3. The electrical device according to claim 2 , wherein the second insulating film comprises at least one holding member adapted to be attached to the holding member of the first insulating film.

4. The electrical device according to claim 2 , wherein the second insulating film has at least one protrusion inserting in the cavity of the casing to be embedded in a filling material of the cavity of the casing, said protrusion being located at an opposite edge of the second insulating film with respect to the holding member.

5. The electrical device according to claim 4 , wherein the first insulating film has at least one protrusion inserting in the cavity of the casing to be embedded in a filling material of the cavity of the casing, said protrusion being located at an opposite edge of the first insulating film with respect to the holding member.

6. The electrical device according to claim 5 , wherein the first insulating film is of plastics.

7. The electrical device according to claim 6 , wherein the first insulating film is held by a first mechanical means, for example an adhesive material, against the surface of the first conductor and by a second mechanical means with a different nature, for example by welding, on the mechanical element.

8. The electrical device according to claim 5 , wherein the first insulating film has at least one fold so as to fit in the surface of the first conductor and is held against said surface of the first conductor only by the first holding member and by the protrusion.

9. An electrical equipment comprising a housing and an electrical device, according to claim 3 , housed in said housing, in which electrical equipment, said first insulating film is configured to electrically insulate the first conductor from a wall of said housing of the electrical equipment or other components of the electrical equipment located in said housing of the electrical equipment, said second electrically insulating film being configured to insulate the conductors from each other.

10. The electrical equipment according to claim 9 , configured to be onboard a vehicle, and forming a power inverter configured so as to supply an electric motor driving the vehicle from a battery, or a DC-DC converter configured to convert a voltage between a high voltage power battery and a low voltage power battery, or an electrical charger configured to convert a voltage between an electric power grid external to the vehicle and a battery of the vehicle.

11. The electrical device according to claim 3 , wherein the second insulating film has at least one protrusion inserting in the cavity of the casing to be embedded in a filling material of the cavity of the casing, said protrusion being located at an opposite edge of the second insulating film with respect to the holding member.

12. The electrical device according to claim 6 , wherein the first insulating film has at least one fold so as to fit in the surface of the first conductor and is held against said surface of the first conductor only by the first holding member and by the protrusion.

13. The electrical device according to claim 7 , wherein the first insulating film has at least one fold so as to fit in the surface of the first conductor and is held against said surface of the first conductor only by the first holding member and by the protrusion.

14. The electrical device according to claim 1 , wherein the first insulating film has at least one protrusion inserting in the cavity of the casing to be embedded in a filling material of the cavity of the casing, said protrusion being located at an opposite edge of the first insulating film with respect to the holding member.

15. The electrical device according to claim 2 , wherein the first insulating film has at least one protrusion inserting in the cavity of the casing to be embedded in a filling material of the cavity of the casing, said protrusion being located at an opposite edge of the first insulating film with respect to the holding member.

16. The electrical device according to claim 3 , wherein the first insulating film has at least one protrusion inserting in the cavity of the casing to be embedded in a filling material of the cavity of the casing, said protrusion being located at an opposite edge of the first insulating film with respect to the holding member.

17. The electrical device according to claim 1 , wherein the first insulating film is of plastics.

18. The electrical device according to claim 2 , wherein the first insulating film is of plastics.

19. The electrical device according to claim 3 , wherein the first insulating film is of plastics.

20. The electrical device according to claim 4 , wherein the first insulating film is of plastics.
