AI Technical Summary

Technical Problem

The existing electronic detonator without detonation is small in thickness and reduced binding force, resulting in limited loading of the detonator and high risk of semi-explosion, which affects the safety of use.

Method used

The tube shell design includes upper, middle and lower detonator shells. It is connected by the lower and upper steps to ensure the thickness and stability of the tube wall. The electronic chip capacitor ignition assembly is installed in the upper detonator shell to replace traditional detonator drugs and realize capacitor excitation ignition. .

Benefits of technology

It improves the charge and safety of the detonator, reduces the risk of half-explosion, enhances impact resistance and high temperature resistance, reduces safety hazards, and achieves the overall stability and efficient ignition of the detonator.

Abstract

The utility model relates to the technical field of coal mine allowable electronic detonators, and discloses an initiating explosive-free electronic detonator, which is characterized in that a lower step is arranged at the joint of a lower detonator shell and a middle detonator shell, and an upper step is arranged at the joint of the middle detonator shell and an upper detonator shell; the lower detonator shell is filled with tertiary explosive; the lower section of the middle detonator shell is filled with fourth-time powder, the third-time powder and the fourth-time powder are spaced through an eyeless cap, and the edge of the bottom face of the eyeless cap abuts against the inner side face of the lower step; an eyelet cap is mounted in the upper section of the middle detonator shell, the bottom surface of the eyelet cap is filled and pressed on the upper surface of the quartic explosive, and the edge of the top end of the eyelet cap is flush with the height of the upper step; an ignition assembly is mounted in the upper detonator shell, a rubber plug clamped at the opening of the upper detonator shell is arranged at the upper end of the ignition assembly, and a lead of the ignition assembly penetrates out of the rubber plug. According to the device, accidents such as semi-explosion caused by reduction of constraining force are effectively reduced, and the safety of the initiating-explosive-free electronic detonator is improved.
