Abstract

An electrical core of an aircraft is provided. The electrical core includes at least one shelf on which is disposed at least one module containing components and comprising at least one input able to be linked to at least one power supply cable and at least one output able to be linked to at least one output cable. In the module, the output cable or cables travel under or in the shelf disposed under the module.

First claim

What is claimed is:

1. An electrical core of an aircraft comprising:
at least one shelf on which is disposed at least one module, the at least one module having a substantially planar face containing components and including at least one input connection on a rear face of the at least one module at a first edge of the substantially planar face, the at least one input connection being configured to be linked to at least one power supply cable,
wherein the substantially planar face of the at least one module further includes a protuberance along a second edge of the substantially planar face opposite the first edge, wherein the protuberance extends below the at least one shelf and comprises a face configured to coincide with at least one lip of the at least one shelf, and wherein the protuberance supports at least one output connection of the at least one module; and
wherein the at least one output connection is configured to be linked to at least one output cable and is situated on the face of the protuberance coinciding with the at least one lip of the at least one shelf on an opposite side of the at least one shelf from the at least one input connection,
wherein the at least one shelf has a hollow structure so that the at least one output cable travels in the hollow structure of the at least one shelf.

2. The electrical core according to claim 1 , wherein the at least one input connection is configured to connect to the at least one power supply cable with a first part secured to the at least one module and is configured to cooperate with a second part provided at the end of the at least one power supply cable.

3. The electrical core according to claim 2 , wherein the at least one input connection and the at least one output connection are connectors of a rackable type which ensure automatic guidance and insertion of male elements of the connectors into corresponding female elements of the cables.

4. The electrical core according to claim 1 , wherein the at least one module groups together at least two components disposed in a direction parallel to a depth of the electrical core.

5. The electrical core according to claim 1 , further comprising at least one extension which extends from a rear of the electrical core to a connection panel offset with respect to at least one side of the electrical core.

6. The electrical core according to claim 5 , wherein the extension comprises a copper electrical conducting element for each of a plurality of phases for each of a second plurality of generating lines.

7. The electrical core according to claim 6 , wherein each copper conducting element is rigid and takes the form of a bar.

8. The electrical core according to claim 6 , wherein the extension comprises for each conducting element a rigid conduit made of an electrically insulating material, the rigid conduit having a sufficient cross-section so that the conducting element is separated from the interior face of the rigid conduit by an air gap concentric with the conducting element.

9. The electrical core according to claim 8 , wherein the extension comprises conduit pads for maintaining the separation around the conducting element.

10. The electrical core according to claim 8 , wherein the rigid conduit consists of two assembled half-shells.

11. The electrical core according to claim 5 , wherein the extension comprises a Z-profile.

12. An aircraft, comprising:
a cabin with an electrical network, and in a nose of the cabin is provided a nose cone containing an electrical network including at least one electrical cabinet,
wherein the electrical cabinet comprises an electrical core that connects between the electrical network of the cabin and the electrical network of the nose cone, wherein the one electrical core comprises:
at least one shelf having a lip and a hollow structure; and
at least one module having a substantially planar face containing components and including at least one input connection on a rear face of the at least one module at a first edge of the substantially planar face, the at least one input connection being configured to be linked to at least one power supply cable,
wherein the substantially planar face of the at least one module further includes a protuberance along a second edge of the substantially planar face opposite the first edge, wherein the protuberance extends below the at least one shelf and comprises a face configured to coincide with the at least one lip of the at least one shelf, and wherein the protuberance supports at least one output connection of the at least one module; and
wherein the at least one output connection is configured to be linked to at least one output cable and is situated on the face of the protuberance coinciding with the at least one lip of the at least one shelf on an opposite side of the at least one shelf from the at least one input connection so that the at least one output cable travels in the hollow structure of the at least one shelf.

13. The aircraft according to claim 12 , wherein the nose cone comprises a connection panel offset with respect to at least one side of the electrical core, and wherein the electrical core comprises at least one extension which extends from a rear of the electrical core to the connection panel.

14. The aircraft according to claim 13 , wherein the extension comprises a copper electrical conducting element for each of a plurality of phases for each of a second plurality of generating lines.

15. The electrical core according to claim 14 , wherein the extension comprises for each conducting element a rigid conduit made of an electrically insulating material, the rigid conduit having a sufficient cross-section so that the conducting element is separated from the interior face of the rigid conduit by an air gap concentric with the conducting element.
