The present invention relates to an igniting/firing element with a casing (1) receiving electrical junction lines connected to an igniting jumper (3) on a chip (2) provided with at least one igniting unit (4a, 4b). In order to allow for the invention to be universally used and to avoid uncontrolled discharge, it is suggested that the junction lines be designed in the form of pins, which are led to the casing (1) through a glass seal, and that the casing bottom (1) be a metal body (7) in which bores (8) are provided for said glass seals (6) to pass through, and that the metal body be positive-fit to the plastic body (9) covering the peripheral wall of the casing (1) and wrapping the pin tips (5) emerging from the glass seal (6).

La présente invention concerne un élément d'allumage doté d'un boîtier (1) dans lequel passent des lignes de raccordement électrique reliées à un cavalier d'allumage (3) monté sur une puce électronique (2) pourvue d'au moins un bloc d'allumage (4a, 4b). Pour permettre l'utilisation universelle de l'invention et éviter une décharge involontaire, il est proposé de concevoir les lignes de raccordement sous forme de pointes (pins) amenées dans le boîtier (1) par une traversée de verre (6), que le fond du boîtier (1) soit un corps métallique (7) présentant des alésages (8) dans lesquels pénètrent les traversées de verre (6), et que le corps métallique soit en liaison de forme avec le corps de plastique (9) qui recouvre la paroi périphérique du boîtier (1) et enveloppe les extrémités des pointes (5) ressortant de la traversée de verre (6).
