在冲击片雷管中，金属箔在高电压大电流作用下爆炸汽化，在加速膛的共同作用下从箔上覆盖着的塑料薄膜中切割出一小片，该塑料小片在加速膛中被加速到每秒几百以至几千米的速度，尔后撞击相当于一片阿斯匹林药片大小的高密度纯感炸药片，引起爆轰。这种雷管不需用起爆药；而钝 In the impingement detonator, the metal foil explodes and vaporizes under the effect of high voltage and large current. A small piece is cut out from the plastic film covered by the foil under the action of the accelerating chamber. The plastic piece is accelerated to Seconds hundreds and even thousands of kilometers, then hit the equivalent of a piece of aspirin tablets of high-density pure explosives, causing detonation. This detonator does not require primer; and blunt
