Abstract

PROBLEM TO BE SOLVED: To prevent a device from being stopped to operate due to the wrong insertion of a dry battery to be opposite in polarity in the case of a visually handicapped person or emergency by keeping the polarity of a lead wire normal regardless of the polarity of the dry mattery in a case. SOLUTION: The respective parts corresponding to the positive polarity and the negative polarity are connected to each other on the upper and lower covers of a case, and the upper lead wire is '+', and the lower lead wire is '-'. When it is a positive connection, + is led from the upper cover, and - is led from the lower cover, and when it is reverse connection, + is led from the lower cover to be guided to the upper part, and - is led from the upper cover to be guided to the lower part, thereby keeping the polarity of the lead wire normal. In the reverse connection, when the dry battery 1 has + polarity 2 and - polarity 3, the case 3 has + terminal 4 and - terminal 5. Furthermore, the case includes a packing 6 for supporting - terminal of the case, a cover 8 for the case, a lead wire +9, a lead wire -10, and a short- circuit preventing insulation cylinder 11, and * designates a place, where + polarity is stored when the dry battery is inserted correctly. Even if the dry battery is reversed, failure of equipment, inoperative condition, explosion of the dry battery, and short- circuit will not be caused.

正常に維持した。Means for Solving the Problems In order to maintain the normal polarity of the lead wire regardless of whether the connection of the dry battery is normal or reverse, the portions corresponding to the + and-poles of the upper and lower lids of the case are connected to each other. , The upper lead line was +, and the lower lead line was-. In the case of forward connection, + is drawn from the upper lid, and-is pulled out of the lower lid. In the case of reverse connection, + is pulled out from the lower lid and guided to the top,
− Was pulled out from the upper lid and guided to the lower side to maintain the polarity of the lead wire normally.
