气体发生器用电点火管及其发火方法
摘要：
本发明公开一种气体发生器用电点火管及其发火方法，电点火管中的点火药剂为导电药剂，其中掺杂混合有导电物质，以导电药剂代替引火药，所述电点火管的壳体与第一芯电极之间充满所述导电药剂；所述壳体为导电壳体，构成第二芯电极，由于取消了传统的两电极间的桥丝或桥带，不需要复杂的焊桥丝工艺，提高了两电极间的电阻，降低了安全气囊点火误爆的几率，而且增加了在维修和保养过程中的安全性；并且可通过改变电极的距离以及导电物质所占导电药剂的比例，调整导电极间的电阻，易于实现对点火灵敏度的控制。
摘要（英）：

The invention discloses an electric ignition pipe of a gas generator and an ignition way of the electric ignition pipe. An ignition powder in the electric ignition pipe is an electric powder in whichan electric substance is mixed. The replacement of an ignition charge by the electric powder cancels a traditional bridging fibril or a bridging belt between two electrodes and does not need a complexbridging fibril welding technics in addition to improving the resistance between the two electrodes and reducing the ratio of the wrong burst of ignition for an air bag, besides the security of the maintenance and servicing is increased. The control of the ignition sensitivity can be realized by changing the distance of the electrodes and the proportion of the electric substance in the electric powder and adjusting the resistance between the electrodes.
