Portable electric detonator

Abstract

The invention discloses a portable electric detonator. The portable electric detonator comprises an insulating connecting piece, an electric ignition element and a basic detonator; one end of the insulating connecting piece is a structure with the outer sides of metal terminals being wrapped with an insulating elastic material and serves as an electric detonator bayonet plug, and the other end of the insulating connecting piece is used as a junction box for extending to be connected with a wire; the insulating connecting piece and the electric ignition element are fixedly and mechanically through the exposed metal terminals and achieve electric connection; and the basic detonator is arranged outside the electric ignition element in a sleeving mode, and the end part of the basic detonator is clamped with the electric detonator bayonet plug of the insulating connecting piece to form a sealing structure. According to the portable electric detonator, the production process is efficient and rapid, assembling is easy, and using is safe and convenient.

Description

technical field [0001] The invention relates to the technical field of civil blasting equipment, in particular to a portable electric detonator. Background technique [0002] Industrial detonators are widely used civilian detonators. All detonators that use electricity as the initial stimulus energy to ignite and detonate are detonators that involve electricity, and are referred to as electric detonators for short. In the structure of the electric detonator, the simplest structure is the ordinary electric detonator, and the most important component is the electric igniter. In the electronic detonators developed in recent years, the electric igniter has been transformed into an electronic igniter controlled by an electronic circuit, and these are all electric igniters. Electric ignition parts need to be closely combined with the shell of the basic detonator to form a specific form of sealing structure to ensure that the electric detonator can work reliably in various occasio...

AI Technical Summary

Problems solved by technology

[0005] 1. The bayonet plug is processed at the end of the long leg line through injection molding. The injection molding process of the bayonet plug is complicated and the production efficiency is low.

[0006] 2. After the bayonet plug is injected at one end of the long-legged line, there are differences in the structure and state of the two ends of the long-legged line. During the packaging, storage and transportation process, they need to be treated separately, and the two ends cannot be mixed, which increases the difficulty and cost of packaging, storage and transportation.

[0007] 3. After the long leg line is directly processed and connected with the ignition element or the electronic control module through the core wire head reserved during the injection molding of the bayonet plug, the long leg line as a whole needs to passively follow the ignition element or electronic control module to transfer to the follow-up The processing process increases the additional logistics transfer volume and the processing difficulty of the next process with long foot lines

[0008] 4. There are many different meters and specifications of the long-legged wire itself. After the long-legged wire is directly processed and connected with the ignition element or the electronic control module through the wire core and head reserved during the injection molding of the bayonet plug, there is no difference in the original Due to the different lengths of the igniting elements, there are additionally a variety of specification distinctions, which require frequent specification changes during production, which is not conducive to continuous production, and increases additional classification management storage and transportation scheduling costs.

[0009] 5. During the integrated injection molding process of the bayonet plug and the long-legged wire, the high-temperature injection plastic of the bayonet plug will cause the insulation skin of the long-legged wire core to melt, which is easy to form short-circuit unqualified products, and the traditional bayonet plug is made of opaque material, and the card The processing quality inside the mouth plug cannot be checked and judged conveniently, which brings great inconvenience to subsequent processing

[0010] 6. In the traditional integrated structure of long leg line and bayonet plug, the length of the bayonet plug is relatively short, and the exposed length of the bayonet plug of the final electric detonator product is usually about 10mm. It is inconvenient to use and operate on site. Operators Had to handle the position of the base detonator shell, which increased the risk of operation safety and violated the intrinsic safety requirements

Utility model patent 202020193388.2 "A Reinforced Electronic Ignition Part and Its Electronic Detonator" discloses a structure of a fully assembled reinforced electronic igniter and its detonator. The technical problem of fast and convenient connection (bayonet plug) is not solved, and the current conventional assembly method of electric detonators is still used, which cannot meet the requirements of large production capacity, high output, and rapid assembly production.
