Electrical power distribution plate comprising a protected distribution bar

Abstract

Electrical power distribution plate comprising a distribution bar, a first mounting board to which the distribution bar is attached and a contactor connected to the distribution bar. The plate comprises 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.

What is claimed is: 
     
         1 . 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. 
     
     
         2 . Plate according to  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 . Plate according to  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 . Plate according to  claim 3 , wherein the cooling device is bonded to the first mounting board. 
     
     
         5 . Plate according to  claim 3 , wherein the cooling device comprises an aluminum plate. 
     
     
         6 . Plate according to  claim 3 , wherein the cooling device comprises a sealed compartment making it possible to cause a cooling gas or a coolant to circulate. 
     
     
         7 . Plate according to  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 . Plate according to  claim 7 , wherein the second mounting board is attached to the distribution bar by a conductive adhesive. 
     
     
         9 . Plate according to  claim 7 , further comprising electrical components coupled to the electronic routing on the second mounting board. 
     
     
         10 . Plate according to  claim 7 , further comprising an interfacing connection making it possible to couple the said plate to an electrical rack. 
     
     
         11 . Plate according to  claim 10 , further comprising a free portion of 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 . Plate according to  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 . Plate according to  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 . Electrical distribution box comprising an electrical power distribution plate according to  claim 1 .
