The objective of the invention is to: provide a kind of explosion precision height, electricity time-delay millisecond detonator safe in utilization.
Summary of the invention:
It comprises lead-in wire, the detonator body; Between detonator and lead-in wire, an electro-delay system is set.
Electro-delay system is by power circuit, crystal oscillating circuit, and digital identification circuit, the counting delay circuit, electronic switch and energy storage capacitor are formed.
Adopt energy storage capacitor control electronic switch to light the ignition bridge silk that detonates.
With the switch numbers coded system be set the time-delay burst time.
The precision of electronic delay of the present invention can be controlled at below the microsecond, and simple in structure, production cost is low.

Embodiment:
It comprises lead-in wire 3, detonator body 1; Between detonator and lead-in wire, an electro-delay system 2 is set; Electro-delay system is by power circuit, crystal oscillating circuit, and digital identification circuit, the counting delay circuit, electronic switch and energy storage capacitor are formed; Adopt energy storage capacitor control electronic switch to light the ignition bridge silk that detonates; With the switch numbers coded system be set the time-delay burst time.
Embodiment 1:
Electro-delay system adopts following electrical connection (realizing the outage detonation mode): 1 of IC (4060), 16,15,14 pin connect resistance R 9, R8, R7, the end of R5,9 pin connect capacitor C 2 one ends, resistance R 1 one ends, 11 pin connecting resistance R2, one end, 12 pin connecting resistance R3, one end, 16 pin connect the emitter stage of triode N1 (9615), the R1 other end connects the end of adjustable resistance VR1, R2, C2, the other end of VR1 is connected diode D1 (4148) negative pole with the tap of VR1, the negative pole of diode D2 (4148) connects the N1 colelctor electrode, capacitor C 1, the C3 positive pole, the source electrode of controllable silicon S1 (BT169), resistance R 6 one ends, the base stage of N1 connects the R6 other end, the negative pole of the Z1 of Zener diode, R9, R8, R7, the other end of R5 connects the grid of S1, the positive pole of D1, the drain electrode of S1 connects the end of indicator lamp L1, the positive pole of power supply meets R3, the end of R4 and the positive pole of D2, the negative pole of power supply connects the R4 other end, C1, the negative pole of C3, the L1 other end, Z1 plus earth.
Embodiment 2:
Electro-delay system adopts following electrical connection: the 1-6 pin of IC (WHL001 is independently developed application-specific integrated circuit module) connects the input of counting delay circuit J1,16 pin connect positive source, 15 pin connect the source electrode of controllable silicon S1 (JT169), the positive pole of capacitor C 3,9 pin connect the grid of S1, the drain electrode of S1 connects an end of R1 ignition bridge silk, 13,14 pin crystal X1 (32.760Khz) in parallel, 8 pin connect C3 negative pole, the R1 other end, J1 output, power cathode ground connection.
During use, can be with the series connection of some detonators, give the detonator charging of series connection in advance with initiator, treat sufficient required electric weight after, initiator stops charging, and sends the number that detonates (function train of pulse) rapidly.When clock frequency was 32768Hz, 6 digit codes preset 15 2 several system frequency dividers, optional 64 sections delayers of the time that is designed to, every intersegmental 20mS that is divided into.When digital identifier detected correct yard, counter was by the time counting of setting, and when counting was full, electronic switch was opened in overflow pulse, lighted ignition bridge silk, and detonating primer is finished the time-delay initiation process.After initiator stopped charging, the operating current of delayer was provided by energy storage capacitor C, was equivalent to every millisecond detonator all by independently power supply power supply.Therefore, the quick-fried millisecond detonator in back being influenced time-delay and detonates with regard to not blowing up because of series loop.Number detonates and can prevent effectively that the disaster accident that stray electrical current, static, the charging of input mistake etc. bring from taking place.
