INDUCTION DETONATOR (OPTIONS) Russian patent published in 2021 - IPC F42B3/12 

FIELD: explosive technology.

SUBSTANCE: invention relates to the field of electrical means of initiating explosives and can be used in explosive automation devices. According to the first variant, the induction detonator consists of a housing 1 made of dielectric material with walls of different thicknesses in cross-section, and a metal liner 2 in the form of a cup, with an ignitable attachment 3 of explosive material pressed into it. The liner 2 is installed in the housing 1 with an inner wall with a larger thickness in cross-section, and an initiator 4 is installed in the lower part of the liner 2. The heat insulator 5 is located between the coils of the inductor 6, which in turn is located between the heat insulator 5 and the inner side of the housing 1 with a wall of a smaller thickness in cross-section. The induction detonator according to the second variant is made detachable: one part is made in the form of a housing 1 with walls of different thickness in cross-section, equipped with a metal liner 2 installed in a part of the housing 1, with a larger wall thickness in cross-section. The liner 2 is equipped with an initiator 4 located in the heat insulator 5, made in the form of a sleeve with a base located in a part of the housing 1 with a smaller wall thickness in cross-section. Another detachable part of the induction detonator is made in the form of an inductor 6 with terminals, the housing 7 is mated by the inner surface with the outer surface of the part of the housing 1 with a smaller wall thickness in cross-section.

EFFECT: ensuring the reliability of the device operation and safety when exposed to abnormal electrical impulses and static electricity discharge.
