Digital electronic detonator based on solid-state aluminum capacitor

Abstract

The invention discloses a digital electronic detonator based on a solid-state aluminum capacitor. The digital electronic detonator mainly comprises a detonator shell, a leg wire, a bayonet plug, an electronic control module, an ignition element and a basic detonator, and is characterized in that an energy storage capacitor on the electronic control module adopts the solid-state aluminum capacitor,so that the problems of high cost, limited raw materials, low withstand voltage and low capacity of a tantalum capacitor are solved; an injection molding rubber coating process is adopted, the solid-state aluminum capacitor is processed into an injection molding terminal, and the injection molding terminal is welded on a PCB of the electronic control module through pins of a capacitor assembly, so that the problem of module eccentricity caused by the overlarge size of the solid-state aluminum capacitor is solved; in addition, the invention adopts a transient voltage suppressor for electrostatic protection, compared with a traditional point discharge electrostatic protection scheme, the mode does not generate electric sparks due to air breakdown, so that the detonator is prevented from being mistakenly exploded due to the electric sparks.

Description

technical field [0001] The invention belongs to the technical field of electronic detonators, in particular to a digital electronic detonator using a solid aluminum capacitor as an energy storage element. Background technique [0002] With the development of engineering blasting technology, the requirements for blasting engineering are getting higher and higher, and the application of electronic detonators in the blasting process is becoming more and more common. The electronic detonator has the following advantages: First, it uses a microelectronic delay module to replace the traditional delay body. This module uses a crystal oscillator and a counter for delay, which is far more accurate than the traditional detonator in terms of delay accuracy and delay time, so it is especially suitable It is suitable for working faces that require high precision; second, it can easily form a simple and advanced detonation network, and the detonation sequence and delay time can be set on ...
