POWER STORAGE CIRCUIT AND FIRING CIRCUIT OF FUZE

摘要

PURPOSE: A power storage device for a fuse and a detonator circuit are provided to reduce the noise inside the fuse by blocking the power in a target penetrating process and a target colliding and to prevent malfunction of the fuse. CONSTITUTION: A detonator comprises a signal process circuit(250), a detonator circuit(270), and a power storage device circuit. The signal process circuit senses a target colliding and a target and generates a target detecting signal. The detonator circuit stores the power of a fuse and ignites a detonating pipe by applying the power to a detonator according to the target detecting signal. The power storage device circuit discharges until colliding target using the power of the fuse and supplies constant power to the signal process circuit when charging voltage reaches to the threshold value after colliding the target.
