Estimating the term…
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).
Trigger unit for initiating pyrotechnic elements, comprising a switch and control unit, and ignition means and a charge body, with the switch and control unit being ignited by means of an electrical coupling by way of a line, characterized in that the switch and control unit is surrounded by a first housing case, in that this first housing case is connected to a second housing case which contains the charge body, and in that the ignition means goes right into this second housing case so as to be surrounded by the second housing case but not the first housing case.
Trigger unit for initiating pyrotechnic elements, comprising a switch and control unit, an ignition means and a charge body, with the switch and control unit being ignited by means of an electrical coupling by way of a line, characterized in that the switch and control unit is surrounded by a first housing case is connected to a second housing case which contains the charge body, in that the ignition means goes right into this second housing case, in that, at its end that is remote from the second housing case, the first housing case carries the coupling portion of a plug connection between the trigger unit and the line that establishes the electrical coupling in that the free end of the first housing case is formed as a plug socket or contains a plug socket.
