Split assembled type primary explosive-free electric detonator

Abstract

The invention discloses a split assembled type primary explosive-free electric detonator, which comprises a detonator outer pipe, main charge explosive and a detonator inner pipe, wherein the main charge explosive and the detonator inner pipe are embedded in the detonator outer pipe; the detonator inner pipe comprises a detonator inner pipe shell, a leg wire, a leg wire skin, a bridge wire, a bayonet plug, an explosive head, a gas chamber, a fire transmission hole, an explosion propagation element and a detonator outer pipe base; and the explosion propagation element comprises a reinforcing cap and a plurality of layers of auxiliary charge explosive which are embedded in the reinforcing cap in sequence. A split design is adopted for the primary explosive-free electric detonator; and primary explosive with higher sensitivity is replaced by explosive with lower sensitivity, and the design of a charge structure of a plurality of auxiliary charge explosive is adopted, so that the problems that the initiating ability of the existing primary explosive-free electric detonator is poor, the safety is still low, the production cost and the use cost are high and the like are solved.

Description

Technical field [0001] The invention relates to an electric detonator in the field of detonating equipment, in particular to a separate assembly type electric detonator without detonator. Background technique [0002] With the continuous application of advanced industrial technology in the civil explosive industry, the performance of detonating equipment is more safe and reliable, but as far as detonating equipment is concerned, its inherent insecurity still exists, such as the widely used delayed electric detonators and instantaneous power generation. The detonator is still difficult to overcome due to the influence of external current. The electric detonator will cause accidents due to the high sensitivity of the detonator in the detonator during transportation. At this stage, more and more technicians are changing the performance and Technical means such as changing the charge structure in the detonator, choosing other explosives instead of detonators, and using electronic det...
