INDUCTION IGNITER Russian patent published in 2018 - IPC F42C11/04 F42B3/10 F42C19/06 F42C19/12 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to the field of electric means of ignition, namely to the means of initiation of explosives (EXPL), pyrotechnic compositions (PTC), powders, and can be used in devices of explosive automation. Induction igniter consists of body 1 and liner 2, which is made of a dielectric material in the form of a glass with a deaf bottom with different wall thicknesses. In the lower part of liner 2, made with a smaller wall thickness, inductor 5 is installed. In the inner cavity of liner 2 is pressed igniter hinge 3, made of explosive material, which contains metal particles or particles of graphite, performing the initiating function during heating. Liner 2 and inductor 5 are installed inside housing 1, made in the form of a hollow cylinder with a bottom having two holes for the electrical leads of inductor 5. Cavity between inductor 5, liner 2 and housing 1 is filled with glue 4.

EFFECT: invention allows to increase the reliability and safety of the device.
