SMALL-SIZED IMPACT FUSE Russian patent published in 2004 - IPC

FIELD: fuses, in particular, fuses used in ammunition of various types, for example, grenades, mines of mortar shots and other ammunition.

SUBSTANCE: the impact fuse has a firing mechanism, cocking system, pricking detonating cap, beam detonating cap, detonator and a transfer charge that is made stepped with a tapered transition between the steps, the step that is smaller in diameter is directed towards the pricking detonating cap, and that of a larger diameter - towards the detonator and has a variable density growing from the end face with a smaller surface towards the end face with a larger surface. Cross-pieces are provided between the pricking detonating cap and the transfer charge, they are made for prevention of detonation of the transfer charge at an improper operation of the pricking detonating cap and/or of the beam detonating cap and for provision of transmission of the detonating momentum from the pricking detonating cap at its proper operation.

EFFECT: enhanced sensitivity and reliability of transmission of the detonating momentum at an impact with a light obstacle at low speeds, and safety in use.
