FIELD: manufacture of detonators. SUBSTANCE: case 1 houses main charge 2 of high explosive and cap 3. Cap 3 carries decelerating composition 5, igniting composition 6, initial charge 7 and intermediate charge 8. Initial charge 7 has axial duct, decelerating composition 5 has axial conical recess where igniting composition 6 is placed. Intermediate charge 8 interacts with main charge 2. Initial charge 7 is composed of PETN RDX or their mixture with igniting compositions. EFFECT: facilitated manufacture, improved operational characteristics. 1 dwg
