AMPOULE TYPE CHEMICAL ELECTRIC CURRENT SOURCE Russian patent published in 2002 - IPC

FIELD: standby electric current sources in machine engineering, electrical engineering, instrument making. SUBSTANCE: chemical electric current source includes housing in which are arranged: electrode units, ampoules filled with thionyl chloride base non-aqueous electrolyte and pulse pressure source. Ampoules are in the form of bellows and they are connected with electrode units to single electrochemical cell. Electrode units are filled with inert gas under pressure lower than atmospheric one. Breaking membrane is secured to movable cover of ampoule. Tools for opening ampoules are rigidly secured to fixed base of each perforated electrode unit. There is gap between base of electrode unit and ampoule cover; said gap is restricted along outer contour by means of corrugated member. Tool for opening ampoule is in the form of hollow cylindrical punch having teeth with pointed cutting edges along contour of its cutting portion; cutting edges are beveled by angle (10-45)degrees relative to plane of membrane. Teeth of hollow cylindrical punch are uniformly arranged along contour of cutting portion. Pointed angle of cutting edge of punch consists (10-20) degrees relative to lengthwise axis of punch. EFFECT: enhanced operational reliability, lowered delay. 5 cl, 2 dwg
