Abstract

A device for electrically connecting cables where a change of direction occurs. The device includes at least two busbars as well as a plate having independent internal ducts in which the busbars are located, each duct being electrically insulated from the other ducts, the busbars ensuring electrical conduction from one open end of a duct to the other end. The cables are fastened at these open ends and thus do not undergo any deformation, the change of direction taking place inside the plate with the aid of the busbars.

First claim

The invention claimed is:

1. A device for electrically connecting cables comprising:
at least two busbars,
a plate having at least two independent internal ducts in which said busbars are located, wherein the plate is parallelepipedal with a rectangular cross section,
each duct being electrically insulated from other ducts,
said busbars ensuring electrical conduction from one open end of a duct to an opposite end.

2. The device according to claim 1 , wherein the busbars are electrically insulated from one duct to another.

3. The device according to claim 1 , wherein entry and exit ends of a same duct are transversely offset.

4. The device according to claim 1 , wherein the plate is at least partially rigid.

5. The device according to claim 1 , wherein the ducts comprise one or more elbows dividing each of the ducts into a plurality of branches extending in different directions.

6. The device according to claim 1 , wherein the ducts are parallelepipedal with a rectangular cross section which is slightly larger than that of an associated busbar, so that the associated busbar is enveloped by the duct.

7. The device according to claim 1 , wherein one wall of at least one of the at least two ducts is at least partially shared with a wall of another duct.

8. An electrical assembly comprising:
at least four cables, and
a connection device comprising at least two busbars and a plate having at least two independent internal ducts in which said busbars are located, each duct being electrically insulated from other ducts, and said busbars ensuring electrical conduction from one open end of a duct to an opposite end,
an end of the cables referred to as cables entering the connection device having to be connected to an end of cables referred to as the exiting cables, which are not in alignment,

wherein the end of the entering cables is respectively fastened at an open end of a duct located at one edge of the plate and the end of the exiting cables is respectively fastened at an open end of a duct located at another edge of the plate, the cables to be associated being connected by the same duct.

9. The electrical assembly according to claim 8 , wherein the ends of the cables are crimped inside the open ends of the ducts.

10. The electrical assembly according to claim 8 , wherein the busbars are electrically insulated from one duct to another.

11. The electrical assembly according to claim 8 , wherein entry and exit ends of a same duct are transversely offset.

12. The electrical assembly according to claim 8 , wherein the plate is at least partially rigid.

13. The electrical assembly according to claim 8 , wherein the ducts comprise one or more elbows dividing each of the ducts into a plurality of branches extending in different directions.

14. The electrical assembly according to claim 8 , wherein the plate is parallelepipedal with a rectangular cross section.

15. The electrical assembly according to claim 8 , wherein the ducts are parallelepipedal with a rectangular cross section which is slightly larger than that of an associated busbar, so that the associated busbar is enveloped by the duct.

16. The electrical assembly according to claim 8 , wherein one wall of at least one of the at least two ducts is at least partially shared with a wall of another duct.
