Abstract

The invention relates to an electrical equipment, in particular for electrical or hybrid vehicles, comprising a casing, said casing comprising a casing element comprising a side wall and defining an inner space. The side wall of the casing element comprises a material offset towards the inner space thereof forming a zone for connecting the positive terminal and the negative terminal of the electrical energy source such that said material offset overlaps the first electrical conductor and the second electrical conductor only making visible, from the outside of said side wall, the positive visible terminal and the negative visible terminal.

First claim

What is claimed is:

1. Electrical equipment, in particular for electrical or hybrid vehicles, comprising a casing, said casing comprising a casing element comprising a side wall and defining an inner space wherein are mounted:
an electronic power module comprising a plurality of pairs of outer positive and negative terminals configured to exchange a supply energy with an electrical energy source,
an electrical connection bar comprising a first electrical conductor and a second electrical conductor, the first electrical conductor comprising terminals in contact with the positive terminals of the electronic power module, so as to put the positive terminals at the same electrical potential by way of the first electrical conductor, the second electrical conductor comprising terminals in contact with the negative terminals of the electronic power module, so as to put the negative terminals at the same electrical potential by way of the second electrical conductor, at least one of said terminals of the first electrical conductor, called “positive visible terminal”, and at least one of said terminals of the second electrical conductor, called “negative visible terminal”, being adapted to be connected respectively to a positive terminal and a negative terminal of an electrical energy source,
electrical equipment wherein the side wall of the casing element comprises a material offset towards the inner space thereof forming a zone for connecting the positive terminal and the negative terminal of the electrical energy source such that said material offset straddles the positive visible terminal and the negative visible terminal such that, from the outside of said side wall, only the positive visible terminal and the negative visible terminal are visible in the material offset, and
wherein the casing element comprises stringers which are arranged adjacent to the material offset or adjacent to a side wall and are configured to receive a body of the electronic power module.

2. The electrical equipment according to claim 1 , wherein, the side wall has at least partially a U-shape, the material offset forming a connection zone corresponding to a recess situated between the U-shaped branches.

3. The electrical equipment according to claim 1 , further comprising a plurality of support elements connecting between them, a plurality of portions of the side wall and making it possible in particular for the support of the electronic power module, the first electrical conductor and the second electrical conductor.

4. The electrical equipment according to claim 1 , said casing element being one-piece.

5. The electrical equipment according to claim 1 , said casing element being made of a plastic material.

6. The electrical equipment according to claim 1 , wherein the electrical connection bar further comprises an attachment bar on which are mounted the first electrical conductor and the second electrical conductor.

7. The electrical equipment according to claim 1 , further comprising a cover closing a face of the side wall of the casing element.

8. The electrical equipment according to claim 1 , further comprising an electronic control unit, said electronic control unit being mounted in the inner space defined by the side wall of the casing element and being configured to control the electronic power module, in particular such that it converts a direct current into at least one alternating current.

9. The electrical equipment according to claim 1 , said electrical equipment being an inverter configured to be electrically connected, on the one hand, to an electrical machine, in particular of an electrical or hybrid vehicle and, on the other hand, to a high voltage supply battery.

10. The electrical equipment according to claim 9 , wherein the electronic power module is capable of converting a direct current into a plurality of alternating currents called “phase currents”.

11. The electrical equipment according to claim 2 , further comprising a plurality of support elements connecting between them, a plurality of portions of the side wall and making it possible in particular for the support of the electronic power module, the first electrical conductor and the second electrical conductor.

12. The electrical equipment according to claim 2 , said casing element being one-piece.

13. The electrical equipment according to claim 3 , said casing element being one-piece.

14. The electrical equipment according to claim 2 , said casing element being made of a plastic material.

15. The electrical equipment according to claim 3 , said casing element being made of a plastic material.

16. The electrical equipment according to claim 4 , said casing element being made of a plastic material.

17. The electrical equipment according to claim 2 , wherein the electrical connection bar further comprises an attachment bar on which are mounted the first electrical conductor and the second electrical conductor.

18. The electrical equipment according to claim 3 , wherein the electrical connection bar further comprises an attachment bar on which are mounted the first electrical conductor and the second electrical conductor.

19. The electrical equipment according to claim 4 , wherein the electrical connection bar further comprises an attachment bar on which are mounted the first electrical conductor and the second electrical conductor.

20. The electrical equipment according to claim 5 , wherein the electrical connection bar further comprises an attachment bar on which are mounted the first electrical conductor and the second electrical conductor.

21. Electrical equipment, in particular for electrical or hybrid vehicles, comprising a casing, said casing comprising a casing element comprising a side wall and defining an inner space wherein are mounted:
an electronic power module comprising a plurality of pairs of outer positive and negative terminals configured to exchange a supply energy with an electrical energy source,
an electrical connection bar comprising a first electrical conductor and a second electrical conductor, the first electrical conductor comprising terminals in contact with the positive terminals of the electronic power module, so as to put the positive terminals at the same electrical potential by way of the first electrical conductor, the second electrical conductor comprising terminals in contact with the negative terminals of the electronic power module, so as to put the negative terminals at the same electrical potential by way of the second electrical conductor, at least one of said terminals of the first electrical conductor, called “positive visible terminal”, and at least one of said terminals of the second electrical conductor, called “negative visible terminal”, being adapted to be connected respectively to a positive terminal and a negative terminal of an electrical energy source,
electrical equipment wherein the side wall of the casing element comprises a material offset towards the inner space thereof forming a zone for connecting the positive terminal and the negative terminal of the electrical energy source such that said material offset straddles the positive visible terminal and the negative visible terminal such that, from the outside of said side wall, only the positive visible terminal and the negative visible terminal are visible in the material offset, and
wherein the casing element comprises blocking walls which are arranged adjacent to the side wall and are configured to receive mounting elements of phase conductors adapted
