Abstract
A fuse box in which wire distribution blocks each have a receiving chamber and a metal wire clip in the receiving chamber, and tightening up screws are respectively threaded into the wire distribution blocks to compress the respective metal wire clips and to force the respective metal wire clips into positive engagement with respective electric wires. Metal spring plates are mounted in respective oblique insertion holes in the wire distribution blocks to hold fuses in a tilted position, so that less vertical installation space is occupied.
Claims5
A fuse box comprising:
- a mount;
- a plurality of wire distribution blocks respectively fixedly mounted on said mount, said wire distribution blocks including one power input distribution and a plurality of power output distribution blocks each having at least one receiving chamber at one side;
- a plurality of metal wire clips respectively mounted in the receiving chamber of each of said wire distribution blocks and adapted to secure a core of an electric wire, said metal wire clips each comprising two horizontal clamping walls horizontally disposed at different elevations, and two vertical support walls bilaterally disposed between said horizontal clamping walls, said vertical support walls and said horizontal clamping walls defining a receiving space adapted to receive the core of an electric wire, said horizontal clamping walls each having a plurality of transverse ribs formed on an inner surface thereof and having a front end terminating at a serrated portion forming a plurality of teeth projections for conformingly and securely engaging an insulative shell of an electric wire;
- and,
- a plurality of tightening up screws threaded into respective screw holes formed in said wire distribution blocks for depressing said metal wire clips, the serrated portions of each said metal wire clips being thereby forced into engagement with an insulative shell of the electric wire inserted into one of said wire distribution blocks.
