Compact gas generator for electric pyrotechnic systems and a method of producing it

摘要

The compact gas generator for electrically initiated pyrotechnic systems comprises a carrying sleeve (1), in which contacts (2) pass through an insulation and sealing mass (3) and enter subsequently the electric initiator (4) covered with an inner cover (5), with all parts mentioned till now forming together the assembled carrier (6), on which an outer cover (7) is placed from above. The inner cover contains with advantage an enhancing flash composition (8). Between the carrying sleeve (1) and the contacts (2) a sealing sleeve (9) can be inserted. The outer cover contains with advantage a propellant (10). A material of the inner cover (5) and the outer cover (7) is most frequently a metal or a plastic. The method of producing the compact gas generator according to the present invention consists in fixing the contacts (2) in the insulation and sealing mass (3), subsequently creating the electric initiator (4) on the contacts (2) or connecting it with them. The electric initiator (4) is then covered with the inner cover (5) and the carrier (6) assembled in this manner is covered with the outer cover (7) from above, with which it is hermetically joined in the place of the carrying sleeve (1). The connection of the outer cover (7) with the carrying sleeve (1) is achieved with advantage by laser welding.
