FIELD: low-voltage apparatuses, in particular, fuses, can be used in chemical sources of energy, having a cylindrical shape. SUBSTANCE: it is offered to manufacture fuses for these sources of energy in the form of a thin metal strip with areas of maximum and minimum cross-sections. The areas of the maximum cross-section serve as contact leads, and the area of the minimum cross- section serves as a fuse element; the cross-section area of the fuse element is to current strength as (200-300):1, and its length is to the thickness as (100-200):1. One of the contact leads has two recesses symmetrically arranged on the side surface; the width of the narrow area between the recesses is 2 to 4 times larger than the diameter of the sealed lead of the chemical source of energy. EFFECT: enhanced explosion - proofness and simplified technology of manufacture. |
