PROTECTIVE DETONATING DEVICE Russian patent published in 2007 - IPC F42C15/00 

FIELD: devices producing detonating moment for blasting of explosives of various ammunition and at blasting operations.

SUBSTANCE: the device has a plate with two inlets and one outlet, coupled by a detonation duct. The ducts form between the first inlet and outlet a long and a short branches with linking of the second inlet to the short branch. Actuating elements destroying the detonation linkage are installed at the joints of the long and short branches and of the shot branch with the second inlet. The first inlet is coupled to the means of detonation excitation. The actuating element is made in the form of a charge of an igniting compound it is positioned at the joint of the short-branch and the second inlet and installed un the side of the detonation duct. A partition is made between the short and long branches at their joint, and a connector is made on the other side of the joint for its displacement under the action of a blast. The detonation duct and the actuating element at the joint of the long and short branches are made of a secondary explosive.

EFFECT: enhanced safety and reliability of the device functioning in the conditions of influence of the climatic end mechanical factors, as well as enhanced adaptability to manufacture.
