The invention provides an electric
detonator ignition device without a sensitive initiating
explosive device drug. The electric
detonator ignition device comprises a shell and an inner core covered in the shell, wherein the inner core is a
tantalum metal block with a spongy porous structure and is internally filled with irregular pores which are communicated with one another; a unilateral conducting layer, a negative main body layer, a
graphite conducting layer and a silver conducting layer sequentially cover the surfaces of the porous structure and the geometric profile of the
tantalum metal block; a positive input end penetrates through the negative main body layer and the unilateral conducting layer to be connected with the
tantalum metal block; the shell is a semi-closed rectangular box body, the middle part of the front face of the shell is provided with a groove from top to bottom, and the inner core is partially exposed out of the groove; the groove aligns to a connection part of a negative end
electrode pin and the silver conducting layer; insulating fillers are filled between the shell and the inner core. The ignition device disclosed by the invention is large in
working temperature range, high in ignition spraying temperature, great in pressure, long in
duration time, far in acting distance, high in high-
temperature resistance and anti-jamming capability, small in size and safe and convenient in storage and transportation, and is suitable for application of an electronic digital
detonator with automatic delaying function.
