Fuse box
First Claim
1. A fuse box that is mountable on an upper surface of a battery and directly connectable with a battery post of the battery to form an electrical connection, comprising:
- the fuse box mountable to the upper surface of the battery;
a battery fuse accommodated in the fuse box having an input terminal and an output terminal;
a battery terminal having a pair of fastening pieces projecting from both ends of a circular arc portion fittable on the battery post;
an input-side bus bar accommodated in the fuse box, the input-side bus bar being fastened to the input terminal of the battery fuse with a bolt;
a connection piece integrally formed on the input-side bus bar that overlaps a side surface of one of the fastening pieces of the battery terminal, the connection piece also being formed with a bolt opening that communicates with a bolt opening of each of the fastening pieces;
the bolt extendible through the bolt openings and a nut fastenable onto the bolt to fasten the connection piece and the fastening pieces together and to fasten the battery terminal onto the battery post; and
an output-side bus bar accommodated in the fuse box, the output-side bus bar being fastened to the output terminal of the battery fuse with another bolt.

Abstract
A fuse box includes a lower cover and an upper cover mounted on an intermediate case to form a box. A large-capacity fuse having an input terminal and an output terminal projecting in substantially opposite directions from one side surface of a body of the fuse is accommodated sidelong in the box within the lower cover and the upper cover to make a height of the fuse small. This makes the fuse box compact. The fuse box may be directly mounted on a battery by fixedly mounting it to an upwardly projecting batter post. An input-side bus bar to be accommodated in the box and the input terminal are fixed to each other with a screw, with one end of the input-side bus bar overlapping the input terminal. An output-side bus bar to be accommodated in the box and the output terminal are fixed to each other with a screw, with one end of the output-side bus bar overlapping the output terminal. A connection piece rigidly mounts the fuse box to the battery post.
