Abstract

A circuit protection assembly includes a mounting block, a unitary fuse assembly, a post assembly and a plug connector. The unitary fuse assembly is disposed the mounting block and includes a plurality of fuses each of which is defined by a portion of a bus plate disposed on the lower surface of the mounting block to form a first terminal of the fuse, a second terminal disposed at least partially on the upper surface of the mounting block and a fuse element connecting the first terminal and the second terminal. The post assembly is disposed at least partially within the mounting block and a post extending from the block. The plug connector extends from a portion of the first terminal of at least one of the plurality of fuses.

Claims

1. A circuit protection assembly comprising:

a mounting block having a wall disposed substantially orthogonal to an upper surface and a lower surface and a recess cavity in said upper surface; and

a plurality of fuses each defined by upper and lower fuse terminals and a fuse element connecting said upper and lower fuse terminals, said fuse element disposed substantially orthogonal to said upper and lower fuse terminals, a first one of said upper fuse terminals having a centrally disposed aperture configured to align with said recess cavity such that said plurality of fuses are disposed partially around said mounting block, said fuse elements are retained adjacent to said wall and said lower fuse terminals are retained adjacent to said lower surface.

2. The circuit protection assembly of claim 1, further comprising a bus bar extending along a length of said lower surface of said mounting block, said bus bar electrically connected with said lower fuse terminals.

3. The circuit protection assembly of claim 2, further comprising a power connection assembly located at a first end of said mounting block and configured to supply power to said bus bar.

4. The circuit protection assembly of claim 3, wherein said power connection assembly further comprises a fuse disposed between said first one of said upper fuse terminals and said corresponding lower fuse terminal.

5. The circuit protection assembly of claim 4, further comprising a post having a first end disposed through said aperture of said first one of said upper fuse terminals and in said recess cavity.

6. The circuit protection assembly of claim 1, wherein said wall has a plurality of recesses over which at least a portion of corresponding fuse elements are disposed.

7. The circuit protection assembly of claim 1, wherein each of said fuse elements are disposed a distance away from said wall to accommodate heat dissipation from each of said fuse elements.

8. The circuit protection assembly of claim 1, further comprising a cover extending from said upper fuse terminals to said lower fuse terminals, wherein said cover is disposed over said fuse elements.
