Abstract

In one aspect of the present invention, a power distribution bus bar that includes a first conductive bus bar configured to receive power from a power source. A plurality of stamped finger-like clamping members are integrally formed to the first conductive bus bar and configured to distribute power to a secondary high power bus bar within a power distribution box. The plurality of stamped finger-like clamping members apply a compression force to the secondary high power bus bar for securing the secondary high power bus bar within the power distribution box.

Claims

1. A power distribution bus bar comprising:

a first conductive bus bar configured to receive power from a power source;

a plurality of clamping members integrally formed to the first conductive bus bar and configured to distribute power to a second conductive bus bar within a power distribution box, wherein the plurality of clamping members are formed as sets of clamping members, each set of clamping members includes a first group of clamping members and a second group of clamping members, and each respective clamping member of the first group alternates with a respective clamping member of the second group for applying a compression force to the second conductive bus bar for securing the second conductive bus bar within the power distribution box.

3. The power distribution bus bar of claim 1 wherein each set of clamping members includes at least four respective clamping members.

4. The power distribution bus bar of claim 1 wherein each of the clamping members is arcuate shaped.

2. (canceled)

5. (canceled)

6. A power distribution box for distributing power from a power source to vehicle electrical components, the power distribution box comprising:

a power distribution box housing;

a detachable bus bar disposed within the power distribution box housing, the detachable bus bar including a plurality of fastenerless terminals for distributing power to output devices, the plurality of fastenerless terminals each having an integrated fuse for terminating power across a respective fastenerless terminal during a power overload condition;

a plurality of housing connectors inserted within the power distribution box housing configured to electrically couple the plurality of fastenerless terminals to an output device conduit; and

a power distribution box bus bar for receiving power from the power source, the power distribution bus bar includes a plurality of like clamping members for distributing power to the detachable bus bar, wherein the plurality of stamped finger like clamping members secure the detachable bus bar within the power distribution box housing.

7. The power distribution box of claim 6 wherein the housing further comprises an electrically conductive stud that is configured for attachment to an output conduit, wherein the detachable bus bar further comprises a terminal having an aperture for receiving the conductive stud, the terminal providing power to the output conduit via the conductive stud.

8. The power distribution box of claim 7 wherein the conductive stud is configured to secure the output conduit to the detachable bus bar.

9. The power distribution box of claim 7 wherein the conductive stud is configured to provide power to an alternator.

10. The power distribution box of claim 6 further comprising a module housing configured to support the detachable bus bar, wherein the module housing is configured to be inserted within the power distribution box housing.

11. The power distribution box of claim 10 wherein the plurality of housing connectors are detachable from the module housing.

13. The power distribution box of claim 6 wherein the module housing includes locating studs for locating the plurality of terminals of the bus bar on the module housing.

14. The power distribution box of claim 6 wherein the module housing includes locating guides for locating the bus bar within the module housing.

15. The power distribution box of claim 6 wherein the detachable bus bar further includes a main body portion, wherein the main body portion extends at substantially a right angle to the plurality of fastenerless terminals for seating against the module housing.

12. (canceled)

16. A power distribution box for distributing power from a power source to vehicle electrical components, the power distribution box comprising:

a power distribution box housing;

a first bus bar disposed within the power distribution box housing, the first bus bar including a plurality of terminals for distributing power to output devices, the plurality of terminals each having an integrated fuse for terminating power across a respective terminal during a power overload condition;
