AN INITIATOR INCLUDING A ZONE OF WEAKNESS

摘要

The present invention relates to an electropyrotechnic initiator comprising: an ignition support (10); an electrical initiation system (11) connecting the ignition support (10) to a source of electricity; and a cap (2) containing at least one explosive composition, the cap being of generally cylindrical shape presenting an open first end (20) connected to the ignition support (10) , an opposite second end that is closed by an end wall (21) , and a peripheral side wall (22) which presents at least one zone of weakness (3). This initiator is essentially remarkable in that at least one of the zones of weakness extends along a non-closed trace and over a portion only of the side wall (22), i.e. without reaching its opposite ends.
