Summary of the invention

The purpose of the utility model is to overcome above-mentioned technical deficiency, and a kind of accurate, defer time high conformity of being ignited by detonator of defer time is provided, and is fit to the detonator electronic delay detonator that the High Accuracy Control explosion is used.

The technical scheme that the utility model technical solution problem adopts is: the detonator electronic delay detonator comprises pipe, battery, igniting head in detonator, rubber stopper, triggering collision block, metal body, the priming; Be characterized in the metal body, connecting rubber stopper and triggering collision block with time-delay millisecond amount adhesive sticker paster; Trigger collision block and connect self-locking normally-open normally-close switch; The normally-open normally-close switch connects the single-chip microcomputer delay chip with the button connecting pin; The single-chip microcomputer delay chip connects battery and match board head tie point one, two; Match board head tie point one, dual-purpose ignition point connecting line one, two connects the fixedly match board head payment to a porter one, two in the plug of match board heads, and match board head payment to a porter one, two connects igniting heads, during igniting head is contained in and manages in the priming.

The beneficial effect of the utility model is: the detonator electronic delay detonator can be accomplished time-delay accurately, and reliable, Electronic Control extension body delay time is set through the single-chip microcomputer delay chip; The speed of service is fast, and reliability is high, and delay adjustments is easy; Simple to operation; The detonator electronic delay detonator of the utility model changes time-delay, and the parameter that only needs to change electro-delay system gets final product, and debugging easily, accurately.Lead quick-fried electronic delay detonator and colliery detonator and be used, can be used for the dangerous field of employment of gas and mineral dust explosion.
