Abstract
A plurality of cells are disposed in close contact with each other with their longitudinal axes parallel to each other, and their electrode terminals that are juxtaposed at one end are electrically connected to each other with a connector piece. These cells thus joined together are inserted into and held within a frame body formed in one-piece with a pair of end face covers, connecting bar, and retaining piece, or alternatively, inserted into and held within a cell casing having a pair of end face covers, bottom wall, and partition boss formed integrally therewith.
Claims17
A packed battery, comprising:
- a plurality of cells joined together in series- or parallel-connection and arranged with their axes parallel to each other and their external surfaces in proximity to or in contact with each other, and with their juxtaposed electrode terminals electrically connected to each other at least at one end with a connector piece;
- and
- a frame body into which said cells are mounted, including a pair of first and second end face covers that respectively cover the entire surface of end faces of the adjacent cells at both ends, a connecting bar for connecting said pair of end face covers opposed to each other at a space corresponding to a length of the cells, all of which end face covers, and connecting bar are formed in one piece, wherein
- said cells are held at their lengthwise ends by the end face covers and at their widthwise sides by the connecting bar, thereby being retained in the frame body, and wherein
- a heat-sensitive or heat-shrinkable outer label is wound around and bonded to the entire exterior surface of the cells and the frame body.

- and
- a cell casing into which said cells are mounted, including a pair of first and second end face covers that respectively cover the entire surface of end faces of the adjacent cells at both ends, a bottom wall that connects said pair of end face covers opposed to each other at a space corresponding to a length of the cells, and a partition boss projected on the bottom wall along a lengthwise direction thereof, all of which end face covers, bottom wall, and partition boss are formed in one piece, wherein
- said cells are placed upon the bottom wall along the partition boss and held at their lengthwise ends by the end face covers, thereby being retained in the cell casing, and wherein
- a heat-sensitive or heat-shrinkable outer label is wound around and bonded to the entire exterior surface of the cells and the cell casing.
