Electronic delay type ignition device and blasting cap electric

摘要

(57) Abstract As for the electronic delay type ignition device of this invention, possessing the solid-state oscillator Drive by the energy which is accumulated to the condenser for firing and the condenser for the said firing which accumulate the energy which is necessary for firing with the voltage impression from external power source receiving the electronic timer section and the said output signal which after the specified time elapsing output the signal, receiving the switching section and the said firing energy which transport the said firing energy to the ignition section, being the electronic delayed type ignition device which possesses the said ignition section where the initiating explosive fires, in the voltage impression field from power source outside aforementioned, the aforementioned electronic timer Drive, at the same time aforementionedThe switching section operates, but this time receiving the energy from the condenser for aforementioned firing, the aforementioned initiating explosive does not fire, there is a voltage impression field.
