AN ELECTRONIC TIME FUZE

PURPOSE: An electronic time fuze is provided to prevent the malfunction generated by electrical noise and to obtain safety by supplying the detonating current in a specific condition. CONSTITUTION: An electronic time fuze(100) comprises a power supply unit(110), a detonating pipe(160), a detonating circuit unit(150), an analog switch circuit unit(140), a data input unit(120), and a controller(130). The data input unit receives a command to start countdown and time information in the controller through a covered conductor. The data input unit includes a DC block capacitor or a voltage distributor and an RC low pass filter. The controller outputs a signal to operate the analog switch circuit unit before detonating time and outputs a detonating signal when reaching the time value by the time information.
