Abstract

An electrical cabinet of an aircraft is provided. The electrical cabinet includes at least one motherboard including on a first face sockets into which are plugged PCB boards ensuring one or more electrical functions, the said electrical cabinet being linked to the electrical circuit of the aircraft organized as various electrical harnesses by way of an electrical connection system, characterized in that the electrical connection system comprises at the level of the second face of the motherboard at least one additional layer, the free face of the last additional layer comprising sockets each ensuring electrical connection with an electrical harness of the aircraft, the additional layer or layers comprising tracks which make it possible to reorganize the electrical circuits emanating from the sockets intended for the PCB boards so as to render them compliant with the sockets intended for the harnesses of the aircraft.

First claim

What is claimed is:

1. An electrical cabinet of an aircraft, comprising:
at least one motherboard having a first face and a second face, and including on the first face sockets into which are plugged PCB boards ensuring one or more electrical functions, the electrical cabinet being linked to an electrical circuit of the aircraft organized as various electrical harnesses by way of an electrical connection system,
wherein the electrical connection system comprises at the level of the second face of the motherboard at least one additional layer, a free face of the at least one additional layer comprising sockets each ensuring electrical connection with an electrical harness of the aircraft, the at least one additional layer comprising tracks which make it possible to reorganize the electrical circuits emanating from the sockets intended for the PCB boards so as to render them compliant with the sockets intended for the electrical harnesses of the aircraft.

2. The electrical cabinet according to claim 1 , wherein the at least one motherboard further comprises several motherboards disposed vertically one above another.

3. The electrical cabinet according to claim 2 , wherein the several motherboards are provided at the level of the rear face of the electrical cabinet.

4. The electrical cabinet according to claim 3 , further comprising rails at the rear of the electrical cabinet to hold the electrical harnesses of the aircraft vertically.

5. An electrical cabinet for an aircraft having a plurality of electrical harnesses, the electrical cabinet comprising:
at least one motherboard having a first face with at least one first socket and a second face opposite the first face, wherein each of the at least one first sockets is configured to receive a PCB board for providing one or more electrical functions; and
an electrical connection system configured to link the at least one first socket with the plurality of electrical harnesses, the electrical connection system having an additional layer for each of the plurality of electrical harnesses at the second face, each additional layer including a second socket and a track interconnecting the first and second sockets establishing an electrical connection therebetween, wherein an electrical circuit can be selectively established between the first socket and at least one of the plurality of electrical harnesses for rendering the PCB board compliant with an intended electrical harness of the aircraft.

6. The electrical cabinet according to claim 5 , wherein the at least one motherboard further comprises a plurality of motherboards arranged vertically one above another in the electrical cabinet.

7. The electrical cabinet according to claim 6 , wherein each of the plurality of motherboards is arranged at a rear face of the electrical cabinet.

8. The electrical cabinet according to claim 7 , further comprising at least one rail arranged at the rear of the electrical cabinet and configured to vertically position each of the plurality of the electrical harnesses with respected to the electrical cabinet.
