Abstract
An enclosure 12 for a disposable battery pack 10 for a cordless power tool consists of a pair of end caps 26, 28 retained on the opposite ends of the pack by a central sleeve 30 of adhesive tape. The end caps are of unitary construction, formed from thin plastic sheet, and include raised terminal covers 32, 34, 36 for shielding exposed terminals 20, 22, 24 from inadvertent outside contact. Each terminal cover has a severable tip 50 which is removed when the pack is to be used, to provide an opening 56 for insertion of a terminal connector 60.
Claims24
An enclosure for a battery pack, the pack having opposite first and second ends and including at least one cell and a raised and exposed terminal carried at the first end for providing electrical contact with the at least one cell comprising:
- a first end cap for capping the first end of the battery pack and including a raised terminal cover having a plurality of walls for enclosing the terminal so as to render it contactable by an outside element only by penetration of that element within the walls of the terminal cover;
- and
- means for surrounding the battery pack and overlappingly engaging the end cap so as to retain the end cap on the first end of the battery pack.
An end cap for use with a battery pack, said pack having opposite first and second ends and including at least one cell and a raised and exposed terminal carried at the first end for providing electrical contact with the at least one cell comprising:
- a thin transverse wall of the end cap for juxtaposing transversely with and capping the first end of the battery pack;
- and
- a raised terminal cover having a plurality of walls and integral with the transverse wall, for registering with and enclosing the terminal so as to render it contactable by an outside body only by penetration of the body within the walls of the terminal cover.
An enclosed battery pack comprising:
- a battery pack having opposite first and second ends and including at least one cell and a raised and exposed terminal carried at the first end for providing electrical contact with the at least one cell;
- a first end cap for capping the first end of the battery pack and including a raised terminal cover having a plurality of walls for enclosing the terminal so as to render it contactable by an outside element only by penetration of that element within the walls of the terminal cover;
- and
- means for surrounding the battery pack and overlappingly engaging the end cap so as to retain the end cap on the first end of the battery pack.
An enclosure for a battery pack, the pack having opposite first and second ends and including at least one cell and a projecting and exposed terminal carried at the first end for providing electrical contact with the at least one cell, comprising:
- a first end cap for capping the first end of the battery pack and including a wall transverse to said first end and a raised terminal cover extending from the transverse wall and integral with the cap, the terminal cover having a plurality of walls for enclosing the terminal so as to render it contactable by an outside element only by penetration of that element within the walls of the terminal cover;
- and
- means for surrounding the battery pack and overlappingly engaging the end cap so as to retain the end cap on the first end of the battery pack.
