PURPOSE:To extremely facilitate the replacement of new and old cells by providing an insulating disk having in its center a conductor elastically in contace with the positive electrode of the cell inside a fitting section and engaging a female screw on the inner periphery at one end of an annular body having an opening edge section at the other end hooked with a stop ring coupled with an annular groove near one end of the cell separately with a male screw on the outer periphery of the fitting section. CONSTITUTION:When new and old cells are to be replaced, an annular body (n) is unscrewed and removed from the cell fitting section (f) of a frame section A, the old cell B is extracted to the female screw (o) side together with a stop ring (l), then it can be easily removed from the annular body (n). When the new cell is to be fitted, a protective tube protecting the outer periphery of the cell is peeled off, the stop ring (l) is inserted in a groove B' provided on the outer periphery of the positive electrode side, the bottom section of the cell is inserted from the female screw (o) side of the annular body (n), and when the stop ring (l) is brought into contact with the opening edge section (m) of the annular body (n), the female screw (o) of the annular body (n) is engaged with the male screw (g) on the outer periphery of the cell fitting section (f) of the frame section A so as to press a positive electrode (i) to a conductor (j). |
