IGNITION ARRANGEMENT FOR SEA MINES Russian patent published in 2005 - IPC

FIELD: the invention refers to ignition arrangements for sea mines.

SUBSTANCE: the ignition arrangement has an execution-detonating circuit which includes an operational electrical igniter, a detonator and a connector which provides liaison along the electric circuit of the arrangement with a mine controlling device. At that the arrangement is confined in a protective body of electro conductive material and in it are additionally included a micro switch and kinetically connected with its rod a spring-loaded signal and blocking stoppers and also a runner with blasting cap, a lead charge, a protective electric contour in the form of LC-filters, a launching electrical igniter and a stopper connected kinematically with the runner. At that the front face of the runner has a projection from the side of the blocking stopper. The blasting cap in the runner is displaced relatively to the lead charge located over the detonator and the outputs of the operational electrical igniter installed in the runner are located opposite the contacts of the micro switch. The protective electrical contour is connected with the connector successively. At that its output electrical circuit are disconnected, and the input electrical circuit of the launching electrical igniter is an open circuit through the contacts of the micro switch.

EFFECT: the invention increases security and noise immunity of the ignition arrangement for sea mines.
