Abstract

An electrical distribution box for an aircraft includes first housings configured to receive power modules, second housings configured to receive electronic control modules, and an interface configured for connection of the power and control modules and external electrical members. The interface includes at least one input power busbar extending into at least one of the first housings for connection to at least one of the power modules. The at least one input power busbar is adapted to be connected to a cable of a wiring harness for connection of the at least one power module to the wiring harness.

First claim

What is claimed is:

1. An electrical distribution box for an aircraft, comprising:
first housings configured to receive power modules;
second housings configured to receive electronic control modules; and
an interface configured for connection for each of the power and control modules and external electrical members,
wherein the interface comprises at least one input power busbar extending into at least a first of the first housings for connection to at least one power module of the power modules, and the at least one input power busbar is:
adapted to be connected to a cable of a wiring harness for connection of the at least one power module to the wiring harness; and
configured to provide power to the at least one power module.

2. The electrical distribution box according to claim 1 , wherein the interface further comprises at least one output power busbar extending into the first of the first housings for connection to the at least one power module to supply a load, or for connection within the electrical distribution box or to an other electrical distribution box.

3. The electrical distribution box according to claim 2 , wherein the interface further comprises at least one individual output power connector extending into a second of the first housings for connection to another power module of the power modules in order to supply the load, or for the connection within the electrical distribution box or to the other electrical distribution box.

4. The electrical distribution box according to claim 1 , further comprising at least one individual input power connector extending into the first of the first housings for connection to the at least one power module of the power modules or another of the power modules, the at least one individual input power connector being adapted to receive the cable of the wiring harness.

5. The electrical distribution box according to claim 4 , wherein each of the first housings comprises both the at least one individual input power connector and the at least one input power busbar, and an electrical connection exists between the at least one input power busbar and the at least one individual input power connector.

6. The electrical distribution box according to claim 1 , further comprising:
a control motherboard; and
a main frame including the first and second housings,
wherein the control motherboard is mounted on an exterior of the main frame and is configured to be connected to at least one of the first housings or the second housings.

7. The electrical distribution box according to claim 6 , wherein the control motherboard comprises an input power connector.

8. The electrical distribution box according to claim 6 , further comprising at least one additional frame for fixing to the main frame,
wherein the at least one additional frame includes at least one of the second housings, and the control motherboard is mounted on an exterior of the at least one additional frame for connection to the at least one of the second housings of the at least one additional frame.

9. The electrical distribution box according to claim 1 , wherein:
the at least one input power busbar is a first input power busbar;
the at least one power module is a first power module;
the first input power busbar further extends into at least a second of the first housings for connection to at least two power modules of the power modules, the at least two power modules including the first power module and a second power module of the power modules; and
the first input power busbar is adapted to be connected to the cable of the wiring harness for connection of the at least two power modules to the wiring harness.

10. The electrical distribution box of claim 9 , wherein:
the interface further comprises a second input power busbar distinct from the first input power busbar; and
the second input power busbar extends into at least two of the second housings for connection to at least two control modules of the control modules.

11. The electrical distribution box of claim 10 , wherein the second input power busbar further extends into at least one of the first housings for connection to the at least one power module of the power modules or another of the power modules.

12. An electrical distribution system, comprising at least one electrical distribution box, wherein the at least one electrical distribution box comprises:
first housings configured to receive power modules;
second housings configured to receive electronic control modules; and
an interface configured for connection for each of the power and control modules and external electrical members, and
wherein the interface comprises at least one input power busbar extending into at least a first of the first housings for connection to at least one power module of the power modules, and the at least one input power busbar is:
adapted to be connected to a cable of a wiring harness for connection of the at least one power module to the wiring harness; and
configured to provide power to the at least one power module.

13. The electrical distribution system according to claim 12 , wherein the interface further comprises at least one output power busbar extending into the first of the first housings for connection to the at least one power module to supply a load, or for connection within the at least one electrical distribution box or to an other electrical distribution box.

14. The electrical distribution system according to claim 13 , wherein the interface further comprises at least one individual output power connector extending into a second of the first housings for connection to another power module of the power modules in order to supply the load, or for the connection within the electrical distribution box or to the other electrical distribution box.

15. The electrical distribution system according to claim 12 , further comprising at least one individual input power connector extending into the first of the first housings for connection to the at least one power module of the power modules or another of the power modules, the at least one individual input power connector being adapted to receive the cable of the wiring harness.

16. The electrical distribution system according to claim 15 , wherein each of the first housings comprises both the at least one individual input power connector and the at least one input power busbar, and an electrical connection exists between the at least one input power busbar and the at least one individual input power connector.

17. The electrical distribution system according to claim 12 , further comprising:
a control motherboard; and
a main frame including the first and second housings,
wherein the control motherboard is mounted on an exterior of the main frame and is configured to be connected to at least one of the first housings or the second housings.

18. The electrical distribution system according to claim 17 , wherein the control motherboard comprises an input power connector.

19. The electrical distribution system according to claim 12 , wherein:
