FUSE FOR CYLINDRICAL LITHIUM STORAGE CELLS Russian patent published in 1997 - IPC

FIELD: low-voltage equipment, including fuses, suitable for use in cylindrical storage cells. SUBSTANCE: fuses are made in the form of thin metal strip with maximum- and minimum-section portions. Maximum-section portions function as fusible links; their sectional-area-to-current ratio is (200-300):1 and their length-to-thickness ratio is (100-200):1. One of contact leads has two dents symmetrically arranged on side surface; narrow-portion width between them is two to four times larger than diameter of sealed terminal of storage cell. EFFECT: improved design. 1 dwg, 1 tbl
