Abstract

An integrated power distribution box including an upper level assembly including a printed circuit board comprising at least one electrical component, a lower housing configured to receive at least a portion of the printed circuit board, an intermediate housing configured to be coupled with at least one fuse, a master fuse electrically coupled to the printed circuit board, a lower level assembly including at least one connector corresponding to at least one of the master fuse, the at least one electrical component, and the at least one fuse.

First claim

What is claimed is:

1. An integrated power distribution box comprising:
an upper level assembly including:
a printed circuit board comprising at least one electrical component;
a lower housing configured to receive at least a portion of the printed circuit board;
an intermediate housing configured to be coupled with at least one fuse;
a master fuse electrically coupled to the printed circuit board;

a printed circuit board bus bar that extends laterally outward from the printed circuit board for electrical coupling with the master fuse;
at least one microprocessor electrically coupled to at least one of the master fuse and the printed circuit board; and
a lower level assembly including at least one connector corresponding to at least one of the master fuse, the at least one electrical component, and the at least one fuse.

2. The integrated power distribution box of claim 1 , wherein the master fuse includes a bus bar and at least one high current fuse coupled to the bus bar.

3. The integrated power distribution box of claim 2 , wherein the at least one high current fuse comprises a plurality of high current fuses, wherein at least one of the plurality of high current fuses has a different current rating than another of the plurality of high current fuses.

4. The integrated power distribution box of claim 3 , wherein at least one of the plurality of high current fuses is coupled to the bus bar via foxing.

5. The integrated power distribution box of claim 2 , wherein the bus bar includes at least one coupling portion configured to couple the bus bar to the upper level assembly.

6. The integrated power distribution box of claim 5 , wherein the at least one coupling portion comprises at least one of a snapping portion and an aperture.

7. The integrated power distribution box of claim 2 , wherein the at least one high current fuse comprises a blade-type fuse.

8. The integrated power distribution box of claim 7 , wherein the at least one high current fuse comprising the blade-type fuse includes a first blade-type fuse having a first blade size and a second blade-type fuse having a second blade size.

9. The integrated power distribution box of claim 2 , wherein the at least one high current fuse includes a substantially perpendicular interface portion.

10. The integrated power distribution box of claim 1 , wherein the at least one microprocessor comprises a master fuse microprocessor configured to at least one of monitor and control at least one electrical characteristic of the master fuse.

11. The integrated power distribution box of claim 10 , wherein the at least one microprocessor includes a printed circuit board microprocessor configured to at least one of monitor and control at least one electrical characteristic of the at least one electrical component.

12. The integrated power distribution box of claim 11 , wherein the master fuse microprocessor and the printed circuit board microprocessor are connected to each other and are configured to collectively at least one of monitor and control at least one electrical characteristic of the integrated power distribution box.

13. The integrated power distribution box of claim 1 , wherein the at least one microprocessor comprises a printed circuit board microprocessor configured to at least one of monitor and control at least one electrical characteristic of the at least one electrical component.

14. The integrated power distribution box of claim 1 , wherein the at least one microprocessor communicates with a vehicle controller.

15. The integrated power distribution box of claim 1 , wherein the master fuse is coupled to the printed circuit board via an electrically conducting fastener.

16. The integrated power distribution box of claim 15 , wherein the electrically conducting fastener comprises an 8 mm threaded stud.

17. The integrated power distribution box of claim 1 , wherein the master fuse is coupled to the printed circuit board via at least one electrical terminal.

18. An integrated power distribution box comprising:
an upper level assembly including:
a printed circuit board comprising at least one electrical component;
a lower housing configured to receive at least a portion of the printed circuit board;
an intermediate housing configured to be coupled with at least one fuse;
a master fuse electrically coupled to the printed circuit board;

at least one microprocessor electrically coupled to at least one of the master fuse and the printed circuit board; and
a lower level assembly including at least one connector corresponding to at least one of the master fuse, the at least one electrical component, and the at least one fuse
wherein the master fuse includes a bus bar and at least one high current fuse coupled to the bits bar and the master fuse is coupled to the printed circuit board via welding the master fuse bus bar to a bus bar of the printed circuit board.

19. An integrated power distribution box comprising:
an upper level assembly including:
a printed circuit board comprising at least one electrical component;
a lower housing configured to receive at least a portion of the printed circuit board;
an intermediate housing configured to be coupled with at least one fuse;
a master fuse electrically coupled to the printed circuit board;

at least one microprocessor electrically coupled to at least one of the master fuse and the printed circuit board; and
a lower level assembly including at least one connector corresponding to at least one of the master fuse, the at least one electrical component, and the at least one fuse
wherein the at least one microprocessor is connected to a vehicle controller.

20. The integrated power distribution box of claim 19 , further comprising a printed circuit board bus bar that extends laterally outward from the printed circuit board for electrical coupling with the master fuse.
