The invention relates to trigger units for initiating pyrotechnic elements which usually consist of a switch and control unit, ignition means and an ignition charge body. Said switch and control element is triggered by way of an electric coupling via a line in order to initiate ignition. The line for the electric coupling and the dimensions of the switch and control element which are usually accommodated in an IC housing complicate the design and the automatic assembly of the trigger units. According to the invention, the switch and control element (1) is surrounded by a first shell (2). Said first shell (2) is connected to a second shell (1) which contains the ignition charge body (23). The invention is further characterized in that the ignition means (19) dip into said second shell (21).
L'invention concerne des unités de déclenchement pour amorcer des éléments pyrotechniques, qui comprennent de manière générale une unité de commutation et de commande, un moyen d'allumage et un corps de charge. L'unité de commutation et de commande est déclenchée par un couplage électrique, par l'intermédiaire d'une ligne, afin d'induire l'allumage. La ligne destinée au couplage électrique, de même que les dimensions de l'unité de commutation et de commande, montée de manière générale dans un boîtier de circuits intégrés, compliquent la conception et le montage automatique des unités de déclenchement. A cet effet, il est prévu selon l'invention, d'entourer l'unité de commutation et de commande (1) d'une première gaine (2) et de relier cette première gaine (2) à une seconde gaine (21) contenant le corps de charge (23). Il est également prévu que le moyen d'allumage (19) plonge dans cette seconde gaine (21).
