Problems solved by technology

In particular, there is a disadvantage that if the stopper portion is strongly pressed against the surface of the cylindrical battery in order to reliably prevent the rotation of the cylindrical battery, the frictional resistance becomes larger, and the cylindrical battery cannot be rotated smoothly. insert bracket

Abstract

The present invention inhibits positional displacements of cylindrical cells and prevents or suppresses rotations thereof while implementing a structure with which the cylindrical cells can be smoothly inserted in a holder. This cell module is provided with a plurality of cylindrical cells (1), and a holder in which the respective cylindrical cells (1) are disposed parallel to each other. The holder is provided with a holder body having a holding space (13) for disposing the cylindrical cell (1) in a fixed position, and a sub-holder formed by being stacked on the holder body. The holder body has a stopper part (5) that is deformed toward the surface of the cylindrical cell (1) disposed in the holding space (13). The sub-holder has a pushrod that pushes out the stopper part (5) toward the cylindrical cell (1) while being connected to the holder body. In the cell module, the pushrod presses the stopper part (5) against the cylindrical cell (1) to push the surface of the cylindrical cell(1) disposed in the holding space (13) in a state where the sub-holder is connected to the holder body.

Description

Technical field [0001] The present invention relates to a rotary holder disposed from the battery module using a cylindrical battery holder arranged in a fixed position of the battery module, and particularly to prevent the positional offset cylindrical battery to prevent, suppress. Background technique [0002] Developing a plurality of cylindrical battery holder into the holding space and arranged in parallel attitude battery module. In the battery module, to prevent rotation of the cylindrical battery holder is arranged in a fixed position is important. This is because, if the rotation of the cylindrical battery, it is possible to produce batteries in series, the joint portion of the metal plate is connected in parallel to the bus bar excessive load from being damaged and other ills. Rotation preventing development of a cylindrical battery in the battery module disposed in the holding space of the stent. (Refer to Patent Document 1) [0003] Prior art literature [0004] Paten...
