Abstract

The invention relates to an electric power distribution box for an aircraft, comprising a frame ( 3 ) containing at least one power connector ( 7 ) formed of one or more slide rails ( 8 ) that are able to interact with one end ( 11 ) of a power circuit board ( 9 ), said power circuit board ( 9 ) comprising at least one switching element ( 13 ) for an electric power distribution plate. The invention also relates to an electric power distribution assembly ( 1 ) comprising such a power distribution box.

First claim

The invention claimed is:

1. An electric power distribution box for an aircraft, comprising: a frame comprising at least one power connector formed of one or more slide rails, the one or more slide rails being configured to interact with an end of a power circuit board, the power circuit board comprising a switching element for an electric power distribution plate.

2. The electric power distribution box according to claim 1 , wherein the frame comprises two power connectors that are configured to receive, by sliding, two ends of the power circuit board.

3. The electric power distribution box according to claim 1 , wherein a power connector comprises a power elastic compression means configured to constrain the end of the power circuit board received in said connector.

4. The electric power distribution box according to claim 3 , wherein the power elastic compression means is a power strip configured to hold the power circuit board and to allow heat dissipation.

5. The electric power distribution box according to claim 1 , wherein each of the at least one power connectors is fixed to the frame by a fixing means.

6. The electric power distribution box according to claim 1 , wherein each of the at least one power connectors is configured to receive one or more cables coming from the aircraft.

7. An electric power distribution assembly comprising an electric power distribution box according to claim 1 and at least one power circuit board, the at least one power circuit board comprising at least one switching element for an electric power distribution plate, the at least one power circuit board having an end that is configured to interact, by sliding, with one power connector of the electric power distribution box.

8. The electric power distribution assembly according to claim 7 , wherein the at least one power circuit board comprises a cold plate linked directly to the frame of the electric power distribution box.

9. The electric power distribution assembly according to claim 7 , wherein the at least one power connector comprises a plurality of power connectors, the plurality of power connectors being linked to one another by a plurality of busbars.

10. The electric power distribution assembly according to claim 7 , further comprising at least one electronic board, at least one electronic board and the at least one power circuit board having a substantially identical height and being arranged in parallel with one another.

11. The electric power distribution assembly according to claim 7 , wherein each of the one or more slide rails is configured to receive at least one bar of the power circuit board.

12. The electric power distribution assembly of claim 11 , wherein each of the at least one power connectors is configured to receive at least two bars of the power circuit board.

13. The electric power distribution assembly of claim 11 , wherein at least one of the power connectors includes a number of slide rails equal to a phase of the at least one power circuit board, and the at least one power circuit board includes a number of bars equal to its phase.

14. An electric power distribution assembly, comprising:
an electric power distribution box having a frame with a first power connector formed at least partially from a plurality of slide rails; and
a power circuit board comprising a switching element for an electric power distribution plate, the power circuit board having an end configured to slidably engage the first power connector of the electric power distribution box,
wherein the plurality of slide rails is configured to thermally communicate and to electrically communicate with the power circuit board when the power circuit board is slidably engaged with the first power connector.

15. The electric power distribution assembly of claim 14 , further comprising a second power connector configured to electrically communicate with the first power connector via a busbar.
