A delayed ignition control device and an electronic detonator

Abstract

The invention relates to a delayed ignition device, especially a delayed ignition control device and an electronic detonator for timing initiation. For the problems of the prior art, a delayed ignition control device and an electronic detonator are provided; upon reaching the timing initiation time of the electronic detonator, an energy-storage capacitor can discharge electricity to a detonating fuse head by matching a processor and a switching tube; the component improves the use security of the electronic detonator; meanwhile, in order to prevent the electrostatic influence produced by putting the device into an electronic detonator, an electrostatic protection structure is formed on an electronic detonator cap wire bonding pad accessory in front of a current-limiting resistor. The device comprises a cap wire M and a cap wire N, and comprises an electrostatic protection device, an electronic delay module, an energy-storage device, and a detonating fuse head which are integrated on a printed board. The electrostatic protection device is configured to release static electricity input at any two of the cap wire M, the cap wire N and a detonator shell. The electrostatic protection structure is formed on the cap wire input end bonding pad. The electronic delay module is in both-way communication with an exploder via the cap wire M and the cap wire N.

Description

technical field [0001] The invention relates to a delay ignition device, in particular to a delay ignition control device for timing detonation and an electronic detonator. Background technique [0002] With the development of microelectronic integrated chip technology, the electronic detonator gradually uses the control chip to cooperate with the ignition head to realize the delay control of the electronic detonator. The application number: 201020690573.9, the name is: an electronic delay ignition device. The ignition device has certain defects in terms of production process, product power consumption and electrostatic protection. [0003] The control module has no electrostatic discharge structure, which causes the discharge test of the detonator pins and shells to fail; [0004] The switch is integrated into the chip, which increases the power consumption of the chip.

Problems solved by technology

[0003] The control module has no electrostatic discharge structure, which causes the discharge test of the detonator pins and shells to fail;

[0004] The switch is integrated into the chip, which increases the power consumption of the chip. At the same time, the internal resistance of the electronic switch is relatively large, which affects the ignition reliability of the control module;

[0005] The two single diodes are easy to cause diode reverse connection during the production process, and due to structural limitations, only small packaged diodes can be used, which have low strength and affect product quality;

[0006] 4. The ignition head adopts rigid drug head or other similar drug heads. The preparation of this kind of drug head itself is complicated, and the resistance value of the bridge wire is unstable. It also needs to be connected with the control module by welding. The production efficiency is low and the product quality is not good. to guarantee
