    • The invention relates to an electrical initiator which can be used with an automobile air bag or seat belt pretensioner. The initiator comprises a header, a cup, conducting pins, epoxy pin seals, a bridgewire, a primer, and an output charge. The header and the cup are composed of an insulating dielectric material capable of being ultrasonically welded together. The header secures the pins. Each pin is electrically conductive and each is formed with a buttress knurl to form a seal when each pin is inserted into the header. Additionally, the pins are further sealed to the header by an epoxy sealant. The bridgewire connects the pins together on one side of the header. An electrical signal through the bridgewire generates heat igniting the primer. Primer reacts with the output charge that in turn ignites a solid gas generant that produces gas that fills air bags or activates the gas generator that drives seat belt pretensioners. The primer contacts the bridgewire. The output charge contacts the primer. The output charge is in the cup, and the cup is ultrasonically welded to the header to provide, along with the pin seals, an environmentally secure seal.
    • 本发明涉及一种可与汽车安全气囊或安全带预紧器一起使用的电引发器。 起动器包括集管,杯,导销,环氧树脂针密封件,桥梁,底漆和输出电荷。 集管和杯由能够超声波焊接在一起的绝缘电介质材料组成。 插头固定插脚。 每个引脚是导电的,并且每个引脚形成有支撑滚花,以在每个引脚插入插头时形成密封。 此外,销通过环氧密封剂进一步密封到集管。 桥接器将引脚的一侧连接在一起。 通过桥梁的电信号产生点燃引物的热量。 引物与输出电荷反应,反过来点燃固体气体发生剂,产生填充气囊的气体或激活驱动安全带预紧器的气体发生器。 底漆接触桥梁。 输出电荷接触引物。 输出装料在杯子中,杯子被超声波焊接到集管上,以便与销密封件一起提供环境安全的密封。
