PURPOSE:To make easier the exchange of cell by a procedure in which an U-shaped coupler is provided to a conductive cell cover pressing a cointype cell on one contact from positive(+) surface and also a slope coupler attracting the cell cover toward the cell side is provided to a positive(+) contact ring, and both are coupled with each other. CONSTITUTION:The quide 15 for coupling or detaching a ring-shaped electric insulation of a thickness enough to serve as a spacer to keep the distance between the bottom 1 and the upper cover 2 of a device body is attached integrally with the positive(+) contact ring 11 and the printed plate 3 by means of the screw 16. The quide 15 is housed with the cell B, contacted with the negative(-) contact 12 of the printed plate 3, and then covered with the cell cover 10 and fixed. The fixation is made by coupling the coupler 10a provided to the cell cover 10 with the coupler 11a provided to the positive(+) contact 11 with the inclined coupling surface 11d while rotating the cell cover 10 and also pushing the cell B. |
