FIELD: blasting operations.SUBSTANCE: proximity fuse comprises a housing, in which cavity the current source is mounted, a signal processing unit, a safety-detonating mechanism comprising a contact assembly and a detonator. Additionally, two transmission devices with thermo-opening membranes are mounted, an electron-time device arming, and a self-destruction unit. The transmission devices with their thermo-opening membranes are placed on the outer surface of the housing. The output contacts of the transmission devices are connected by the electric wires to the input terminals of the current source. The signal processing unit is connected by the electric wires to the electron-time arming device, a contact assembly of safety-detonating mechanism and a unit of self-destruction. The output terminals of the current source are connected by the electric wires to the signal processing unit.EFFECT: increase in reliability of triggering.2 dwg |
