ELECTRIC DETONATOR Russian patent published in 2005 - IPC

FIELD: devices for blasting of brisant explosives, in particular, electric detonators with a detonating bridge.

SUBSTANCE: installed in succession on the base are a film bridge, propelled plate, bushing with a through opening corresponding to the shape of the film bridge and made in the form of a rectangle, whose width-to-length ratio is in proportion 1:1,5 to 3, explosive charge that is made tapered on the side of the bushing, and a tapered recess is made in its end face, cap closing the end face corresponds to the shape of the recess, and the taper angle equals the taper angle of the explosive charge. The cap thickness is selected from relation 1/10 to 1/15 of the height of the explosive charge that is made of a heatproof compound with a dispersivity and relative density respectively at least of 8000 sq.cm/g and 0.8.

EFFECT: enhanced safety of handling, enhanced initiating capacity.
