FIELD: blasting operations.SUBSTANCE: invention relates to blasting works, specifically to initiation means based on blasting explosives, triggered by a given mechanical force. Detonating device of mechanical fuse consists of a housing in form of a thin-walled brass cartridge with primer therein, made from main charge of detonating explosive and a metal cup. On detonator is pressed initiating charge of blasting explosive, on which there is a dielectric coupling-insulator with a piezoelectric cell therein without lining on side of initiating charge of blasting explosive and a striker, configured for displacement relative to housing in axial direction to initiating charge of blasting explosive at impact. Detonating device is closed with a plastic cover during transportation or metal before its use.EFFECT: technical result is producing a detonating device of mechanical fuse, which provides high reliability of triggering and safety.1 cl, 1 dwg |
