AMPOULE CURRENT SOURCE Russian patent published in 2020 - IPC F42C19/12 H01M6/02 H01M6/38 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to ammunition, to an energy-containing source of current of a fuse of small-caliber artillery shots. Ampoule current source includes housing with unit of electrodes and glass spring-loaded ampoule, filled with liquid electrolyte mounted with the possibility of longitudinal inertial movement relatively rigidly fixed on the bottom of the body of the firing mechanism until its destruction. Firing mechanism combines function of device for forced acceleration of electrolyte filling of interelectrode space after destruction of ampoule, for this purpose on outer side of firing mechanism symmetrically arranged are blades, which together with it represent a single structural part. At that, the ampoule is closed by the cap casing, which is fixed in the body by the flange and rests on the electrode block. Height of the firing mechanism is selected from the condition of formation of the minimum gap required for ampoule destruction, between it and the ampoule bottom. There are through holes in the blades and the blades are inclined to the longitudinal axis of the firing mechanism at an angle less than 90°, wherein selection of blade inclination angle depends on ammunition rotation speed.

EFFECT: technical result is reduction of time for output to operating mode and achievement of required output power by current source at low ambient temperatures.
