Zusammenfassung:FIELD: blasting.SUBSTANCE: impact detonator containing a body with a cylindrical sleeve located inside, with a through hole in the center, inside which there is a striker provided with a lower part in the form of a truncated cone, a cover of the casing, with a bottom in the upper part contacting the striker, and a bottom with the lower edges canted inside, tightly enclosing the annular budge on the outside of the body. In the lower part of the body there is a product of a blasting agent located above the opening in the cup. The lower half of the product of blasting agent is high-density with a recess in the upper part in the form of a truncated cone. The upper half of the product of blasting agent is low-density and fills the volume inside the body between the upper part of the lower half of the product of blasting agent and an aluminium foil adjacent to the product. There is an annular groove with a seal therein on the outside of the side wall of the cover. Inside the sleeve there is a cup, into which two parts of the blasting agent are pressed, the initiating explosive is placed in the lower part, and a blasting agent is placed in the upper part. In the upper part of the cover on the inside, a recess is formed, shaping an annular groove with the upper part of the striker, which is intended to fill the heat-resistant adhesive therein. The striker in its central lower part is designed in the form of a ring of conical shape and installed in such a way that a gap remains between its lower part and the blasting agent.EFFECT: prevention of unauthorized activation of the impact detonator in a liquid medium in the event of depressurization of the detonation head.1 dwg Изобретение относится к области взрывных работ.
