An anti-static mechanism for electrical explosives

Abstract

The invention discloses an anti-static mechanism of an electric initiating explosive device. The anti-static mechanism comprises a PCB, a housing, an electrode plug and ignition powder, wherein the PCB, the electrode plug and the ignition powder are located in the housing, the PCB, the electrode plug and the ignition powder are sequentially arranged in the housing, the PCB is sealed in the housing, an inner ring circle and sequentially includes an outer ring circle and an outer ring metal layer from inside to outside, the inner ring circle is connected with a leg wire of the electrode plug, the outer ring circle is connected with an external wire, and the outer ring metal layer is connected with the housing. The anti-static mechanism has the advantages of being simple in part machining, low in cost and easy to assemble and control, and the safety problem of current electric initiating explosive devices is solved.

Description

technical field [0001] The invention relates to the field of safety design of electrical explosives, in particular to an antistatic mechanism for electrical explosives. Background technique [0002] Static electricity is often encountered in the production, use and storage of electrical explosives. Due to the ubiquity of static electricity, there are many explosion accidents caused by it, causing huge losses to personnel and property. Static electricity has become the primary factor affecting the safety of electrical explosive devices. [0003] In the process of storage, transportation, service handling, testing and use of electrical explosives, each electrical explosive may experience multiple electrostatic discharge shocks. Generally speaking, it is impossible to accidentally ignite every electric pyrotechnic device due to electrostatic discharge stimulation, but repeated electrostatic discharge shocks may cause a certain degree of insensitivity to the electric pyrotechn...

AI Technical Summary

Problems solved by technology

The first design has a certain probability and cannot really play the role of anti-static

The second design, the cost of insensitivity agent is higher, and the performance of pyrotechnics may be sacrificed to a certain extent

The second design requires a large space, complex craftsmanship, and poor impact resistance

The third design requires small space and poor technological operation, which affects the performance of pyrotechnics

Due to the small size of most pyrotechnic products, the rigidity of the foot line is small, and the size of the air gap is about 0.2mm, the realization of this design technology has problems such as difficult parts processing and assembly process control.
