Firing control element group for digital electronic detonator and production method of firing control element group

Abstract

The invention provides a firing control element group for a digital electronic detonator. The firing control element group comprises a plurality of firing control elements which are connected together through a connector; particularly, the firing control element group comprises a detonator tube plug group, a plurality of ignition control circuit boards, a plurality of igniting elements and a plurality of encapsulation bodies; the detonator tube plug group is composed of a plurality of detonator tube plugs; the detonator tube plug group is formed by connection of the plurality of detonator tube plugs through the connector; the detonator tube plugs, the ignition control circuit boards, the igniting elements and the encapsulation bodies are in one-to-one correspondence, so as to form the plurality of firing control elements; one end of each detonator tube plug is welded with the first end of one ignition control circuit board; the second end of the ignition control circuit board is welded with one igniting element; and the encapsulation bodies which are formed in a low-pressure injection molding manner clad the welding parts of the detonator tube plugs, the welding parts of the igniting elements and the outer surfaces of the ignition control circuit boards. The invention also provides a firing control element group, and a production method of firing control elements. According to the scheme, the waterproof performance, the dustproof performance, the antistatic property and the shock resistance of the electric detonator are improved.

Description

technical field [0001] The invention relates to the technical field of pyrotechnics manufacture, in particular to the improvement of a digital electronic detonator firing control component set and a production method thereof. Background technique [0002] In the existing digital electronic detonator production process, the detonator leg line usually runs through the detonator plug, the detonator plug is welded to the first end of the ignition control circuit board through the detonator leg line, and the second end of the ignition circuit board is welded to the igniter . During assembly, the above-mentioned detonator plug, ignition control circuit board and ignition parts that have been welded are usually put into the detonator fire tube, and the detonator fire tube is bayonet sealed to realize the assembly of the digital electronic detonator. [0003] In the above process, the solder joints of the detonator legs and the solder joints of the igniter are exposed, and there ar...

AI Technical Summary

Problems solved by technology

[0003] In the above process, the solder joints of the detonator legs and the solder joints of the igniter are exposed, and there are many electronic components welded on the ignition control circuit board. When the digital electronic detonator is subjected to vibration, the exposed solder joints and electronic components The device is very easy to loosen or even fall off, which will affect the reliability of the digital electronic detonator

Moreover, external interference factors such as moisture, dust, and static electricity can easily affect the performance of the product, thereby affecting the waterproof, dustproof and antistatic performance of the electronic detonator.
