Abstract
A battery pack including a molded resin portion, which holds a part of or the entire battery, and an externally exposed output terminal. The battery pack further includes an insulating block, which is provided with a breaker mechanism for cutting-off current flow when an over-current flows. The insulating block is held by being inserted in the molded resin portion. The insulating block holds the output terminal on its surface. The output terminal held by the insulating block is held at a prescribed position so as to be externally exposed from the molded resin portion.
Claims13
A battery pack comprising:
- a battery;
- a molded resin portion which holds at least a part of the battery;
- an insulating block which is provided with a breaker mechanism for cutting-off current flow upon detection of an over-current flow, the insulating block being held by being inserted in the molded resin portion;
- an externally exposed output terminal connected to a surface of the insulating block,
- wherein the insulating block holds the output terminal on a surface thereof, and the output terminal held by the insulating block is disposed at a prescribed position so as to be externally exposed from the molded resin portion, and
- wherein the insulating block includes a base block and a cover block, which are separately formed of plastic, the cover block being fastened to the base block, and a holding chamber is formed between the cover block and the base block;
- a fastening metallic member connected to the output terminal;
- and
- a breaker mechanism provided in the holding chamber, wherein the breaker mechanism includes a movable arm, and the movable arm protrudes externally outside of the cover block, and an externally protruding portion of the movable arm is fastened to the fastening metallic member.
