The invention discloses an electronic detonator interface. The electronic detonator interface comprises an electronic detonator chip, a resistor, a three-port common-cathode transient overvoltage protection diode, a voltage-regulator tube, a diode, a quartz crystal and an igniter wire, wherein the igniter wire is connected between functional pins of the electronic detonator chip; one end of the interface resistor is connected with a pin wire, while the other end of the interface resistor is connected with one of the pins of the electronic detonator chip; the resistance of the interface resistor is 100 ohm above; the interface further comprises the three-port common-cathode transient overvoltage protection diode which is connected between the two pins of the electronic detonator chip in series; the interface further comprises the quartz crystal which is connected in series between the two pins of the electronic detonator chip. The electronic detonator interface disclosed by the invention improves the high-voltage alternating / direct current resistance and anti-static performance of the electronic detonator, avoids the wrong explosion risk as the igniter wire inside the electronic detonator is in short circuit and grounded, lowers probability of failure of the electronic detonator, improves the reliability of the electronic detonator, and improves the delay time precision of the electronic detonator.
Description
technical field [0001] The invention relates to the field of pyrotechnics, in particular to the interface part in the field of electronic detonators. Background technique [0002] The research on electronic detonator technology began in the early 1980s, which is the development trend of industrial detonators. Electronic detonators are the product of the combination of integrated circuit technology and pyrotechnics technology. Electronic detonators use chips to replace the delayed gunpowder in industrial detonators. The realization of high-precision delay, safety control, and reliable detonation of electronic detonators depends on chips. [0003] There are some problems in the interface aspect of the existing electronic detonator technical scheme. The ignition head (or bridge wire) is directly in contact with the high voltage on the energy storage capacitor, which may easily cause misfiring of the ignition head and bring potential safety risks to the detonator. There is n...
