Fuse block adapters for terminal blocks
First Claim
1. An adapter for mechanically joining a terminal block and a fuse block;
- the terminal block having at least one external surface, at least one bay recessed in the external surface, and a bay terminal within the bay;
the fuse block comprising opposed first and second sides, fuse engaging means for engaging and carrying at least one fuse fastened to the first side, and fuse terminals for providing electrical contact points with the fuse;
said adapter being independent of fuse engaging and contacting means, for interposition between said terminal block and said fuse block and mounting said fuse block on said terminal block, and comprising a mounting plate member having opposed first and second sides;
first fastening means for attaching the first side of said plate member to the fuse block second side; and
second fastening means for attaching the second side of said plate member to the terminal block adjacent to the external surface thereof.

Abstract
Adapter for securing a terminal block, such as the standard terminal block on a transformer, to one or more standard fuse blocks, requiring a minimum of parts and mounting space. An adapter plate is interposed between the terminal block and the bottom of the fuse block and secured to each. In one embodiment, the conventional terminal screws of the terminal block are used to secure the adapter to the terminal block. In the illustrated embodiments, the adapter plate does not provide any electrical connection between the fuse block and terminal block, this being provided by jumper wires having their respective wire terminals secured to terminals of a joined terminal block and fuse block.
