PURPOSE:To prevent any decrease of output voltage as well as any charging between dry cells installed in a battery case by producing an open circuit when the cell is inserted with a wrong polarity by installing separators for preventing reverse connection in areas at which the dry cells are connected in series. CONSTITUTION:Batteries 5, 5a and 5b are installed in a battery case 1. The positive electrodes 7a and 7b of the batteries 5a and 5b are connected to the negative electrodes of adjacent batteries through the holes of reverse-connection-preventing separators 8 and 8a installed at the joints of the batteries 5, 5a and 5b. As the result, voltage is delivered to a positive terminal 2 and a negative terminal 3 thereby supplying a current to a load 4. When the polarity of the battery 5a or 5b is reversed, their negative electrodes are not connected through the separator 8 or 8a and the whole circuit comes to be in an open circuit state. As the result, no voltage is delivered to the positive and the negative terminals 2 and 3 thereby securing early notice of the mis-insertion of the battery. Furthermore, even when dry cells are used, there is no possibility of the dry cells charging each other because of the open circuit state, thereby preventing any secondary accidents such as liquid leakage which might be caused by the charging of the dry cell. |
