Electrical power distribution plate comprising a protected distribution bar

1. An electrical power distribution plate comprising a distribution bar, a first mounting board to which the distribution bar is attached, a contactor connected to the distribution bar, and a second mounting board attached to the distribution bar so that the distribution bar is placed between the first mounting board and the second mounting board, the distribution bar being bonded to the first mounting board and to the second mounting board by a conductive adhesive.

2. The plate of claim 1 , wherein the contactor is an irremovable contactor mounted on the distribution bar via at least one cut-out made in the second mounting board.

3. The plate of claim 1 , further comprising a cooling device attached to a face of the first mounting board opposite to the face facing the distribution bar.

4. The plate of claim 3 , wherein the cooling device is bonded to the first mounting board.

5. The plate of claim 3 , wherein the cooling device comprises an aluminum plate.

6. The plate of claim 3 , wherein the cooling device comprises a sealed compartment making it possible to cause a cooling gas or a coolant to circulate.

7. The plate of claim 1 , wherein the second mounting board comprises an electronic routing defining an electronic circuit on a surface of the second mounting board opposite to the surface of the said second mounting board facing the distribution bar.

8. The plate of claim 7 , wherein the second mounting board is attached to the distribution bar by a conductive adhesive.

9. The plate of claim 7 , further comprising electrical components coupled to the electronic routing on the second mounting board.

10. The plate of claim 7 , further comprising an interfacing connection making it possible to couple the said plate to an electrical rack.

11. The plate of claim 10 , further comprising a free portion of the distribution bar making it possible to achieve, at one end of the distribution bar a coupling between the distribution bar and a power interface of the electrical rack.

12. The plate of claim 7 , wherein the second mounting board comprises heat-dissipating planes included between the surface facing the distribution bar and the surface on which the electronic routing is produced.

13. The plate of claim 1 , wherein the distribution bar has a thickness of about 2 mm, and the first mounting board has a thickness of about 1.6 mm, and the second mounting board has a thickness of about 0.5 mm.

14. The plate of claim 1 , further including vias extending between a face of the second mounting board facing the distribution bar and a face opposite to the second mounting board.

15. The plate of claim 3 , wherein the cooling device comprises a sealed compartment, cooling of the distribution plate being improved by the use of forced convection.

16. An electrical distribution box comprising an electrical power distribution plate as described in any preceding claim.
