SAFETY-IGNITION MECHANISM OF DETONATING FUSE Russian patent published in 2012 - IPC F42C15/34 

FIELD: blasting.

SUBSTANCE: mechanism comprises a body with two channels made in it, in one of which there is an inertial body, and in the second one - a spring-loaded sting and a cap. Between channels there is a slot, in which a lever is placed, on the long arm of which an inert body rests, and on the short one - a sting. The inert body has a shape of a ball, and at the opposite sides of the inert body placement channel there are ledges that give it zigzag-like motion.

EFFECT: increased safety of detonating fuse in service circulation, and reliability of arming in a wide range of linear accelerations at low dimensions, and reduced labour intensiveness of manufacturing.
