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 an upper and lower surfaces;

a unitary fuse assembly disposed at least partially around said mounting block, said unitary fuse assembly having a plurality of fuses each of which is defined by a portion of a bus plate disposed on the lower surface of said mounting block to form a first terminal of said fuse, a second terminal disposed at least partially on said upper surface of said mounting block and a fuse element connecting said first terminal and said second terminal;

a post assembly disposed at least partially within said mounting block and a post extending therefrom; and

a plug connector extending from a portion of said first terminal of at least one of said plurality of fuses.

2. The circuit protection assembly of claim 1 wherein said plug connector is a first terminal portion and said at least one of said plurality of fuses is a first of said plurality of fuses, said assembly comprising a second plug connector extending from said first terminal of a second one of said plurality of fuses.

3. The circuit protection assembly of claim 1 comprising a connection segment extending from said bus plate for connection to a power source.

4. The circuit protection assembly of claim 1 wherein said mounting block has a plurality of recesses in which at least a portion of corresponding fusible elements are disposed.

5. The circuit protection assembly of claim 4 wherein said recesses are partially defined by a side wall, each of said fusible elements disposed a distance away from said side wall to accommodate heat dissipation from each of said fusible elements.

6. The circuit protection assembly of claim 5 wherein said upper surface of said mounting block includes a plurality of recesses, each of said posts having a first end disposed at least partially within said corresponding recesses.

7. The circuit protection assembly of claim 1 further comprising a cover extending from said first terminal of said fuse to the second terminal of said fuse wherein said cover is disposed over said fuse element.

8. The circuit protection assembly of claim 1 wherein said mounting block includes a recess extending a portion of a length of said upper surface of said block, said recess configured to receive a first end of each of said plurality of posts disposed at least partially within said recess.
