Abstract

Cette invention porte sur un dispositif déclenchant une détonation et s'appliquant sur un détonateur. Ce dispositif comprend deux conducteurs électriques espacés ; une substance résistive s'étendant entre les conducteurs électriques et destinée à libérer une énergie lors de l'application d'un courant électrique sur celle-ci ; et une composition explosive comprenant du diazodinitrophénol (DDNP) et recouvrant la substance résistive. La composition explosive comprend du DDNP sous forme de fines particules et sous forme de particules relativement plus grosses. Le dispositif déclenchant la détonation est non seulement très stable et résistant à une explosion accidentelle, mais aussi très fiable du fait de la présence de DDNP sous forme de fines particules. De plus, la composition explosive du dispositif peut être déclenchée même en présence de faibles niveaux d'énergie auxquels fonctionnent généralement les dispositifs de déclenchement électroniques.
