ABSTRACT:
Pyrotechnic initiators tripped by an electric current passing through a resistive element. These initiators can either be an inflammator, an igniter or a detonator.
The pyrotechnic initiator with coaxial structure includes at least one filament (39) connected to the central conductor (34) and to peripheral conductor (35). To improve operating safety while simplifying the structure of the initiator, it is fitted with a standard coaxial connector (33), the end of which, intended for connection of the filament, is modified. The electrical insulation means, between the two conductors (34) and (35) and the electrical insulation means between the peripheral conductor (35) and the outside of the inflammator, include a common dielectric mass (40).
