ENERGY-CONTAINING SOURCE OF CURRENT Russian patent published in 2013 - IPC F42C19/12 

FIELD: electrical engineering.

SUBSTANCE: independent energy-containing power source of an electronic fuse for small-calibre ammunition rounds is made as a voltaic battery comprising of a spring-actuated glass bulb filled with electrolyte, place inside a permeable bushing adjoining to the coaxial block of bipolar plate electrodes. At that the block is placed between negative and positive electrodes equipped with terminals. Moreover the bulb is capable of longitudinal displacement in respect to a firing pin at the case bottom and closed with a cap-type housing which is fixed by a flange inside the case and is rested on flat end of the bushing and block of electrodes. In permeable bushing there are reach-through holes in axial alignment with gaps between electrodes in the block of electrodes; longitudinal vanes are distributed alongside the inner perimeter. At that bipolar electrodes have ducts and reach-through holes in the permeable bushing are made alternatively in the shape of longitudinal slots at the height of the block of electrodes.

EFFECT: operating speed of the current source at multiple reduction of the warm-up period for electrolytic battery due to forced circulation of electrolyte inside the perforated bushing with its distributed delivery to the voltaic battery.
