Abstract

L'invention porte sur une amorce (10) de détonateur électronique comportant: deux conducteurs électriques espacés (12) situés sur un substrat isolant (14); deux résistances formées par des ponts résistants (16) de film épais s'étendant entre les conducteurs électriques (12) et libérant de l'énergie lorsqu'on applique un courant électrique aux ponts résistants (16); et une composition d'explosifs ou pyrotechnique normalement désignée par un N° de référence (18) recouvrant les ponts résistants (16). On notera que si l'un des ponts est défaillant, l'autre mettra le dispositif (10) à feu, et que la taille de l'interface de contact entre les ponts (16) et la composition explosive (18) est également doublée, ce qui rend le détonateur (10) encore plus fiable. Ladite amorce (10) est utilisable dans un grand nombre d'applications différentes.
