ELECTRICAL INITIATOR WITH SELF-DISCONNECTION FROM CURRENT SOURCE Russian patent published in 1998 - IPC

FIELD: pyrotechnics, in particular, pyrotechnic initiation devices, applicable for initiation of difficulty inflammable pyrotechnic systems or for preheating of various objects. SUBSTANCE: electrical initiator casing accommodates an electric primer, working charge and a bush installed between them, the bush has a cavity connected through ducts to the electric primer and working charge. The duct axes are shifted relative to each other, and the distance between the bush end and the place of entrance to the duct cavity located on the side of this end exceeds the distance between the same end and the place of entrance to the cavity of the other duct located on the side of the opposite end. Electric primer has pyrotechnic compound with nonconducting slags, and working charge is made of pyrotechnic compound with refractory slags. EFFECT: simplified procedure of manufacture, enhanced reliability of self-disconnection from current source. 1 cl, 1 dwg
