Portable electricity-related igniter

Abstract

The invention discloses a portable electricity-related igniter. The igniter comprises an insulating connecting piece and an electricity-related ignition element; one end of the insulating connecting piece is provided with a structure in which the outer side of a metal terminal is coated with an insulating elastic material as an epitaxial electricity-related detonator bayonet plug, and the other end of the insulating connecting piece is used as a junction box for epitaxially connecting a lead; and the insulating connecting piece is mechanically and fixedly connected with the electricity-related ignition element through the exposed metal terminal, and electric connection is achieved. According to the igniter, the structure and the assembly technological process of the electricity-related igniter and an electricity-related detonator can be simplified, the production efficiency is improved, and the igniter can be used for production and use of various electricity-related detonators.

Description

technical field [0001] The invention relates to the technical field of civil blasting equipment, in particular to a portable electric ignition device. 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 all electric detonators. In the structure of electric detonators, the most important device is the electric igniter. In the electronic detonators developed in recent years, the electric igniter has been transformed into an electronic igniter controlled by electronic circuits. These are also electric igniters. Fire starter. The electric ignition element needs 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 under various complex working conditions. [0003] At present, the usual practice in the civil blasting equipment industry is to f...

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, there are many users, and the production efficiency is low.

[0006] 2. After injection molding the bayonet plug 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, which need to be treated separately in the process of packaging, storage and transportation, and the two ends cannot be mixed, which increases the difficulty and cost of packaging, storage and transportation

[0007] 3. After the long-leg wire is directly processed and connected with the ignition-related components through the wire core end reserved during bayonet plug injection molding, the long-leg wire as a whole needs to passively follow the flow of the electrical ignition-related components to the subsequent processing process, increasing It reduces the amount of logistics transfer and the difficulty of processing with long foot lines in the next process

[0008] 4. There are many different lengths and specifications of the long-legged wire itself. After the long-legged wire is directly processed and connected with the electric ignition element through the wire core end reserved during the injection molding of the bayonet plug, it leads to the original undifferentiated electric-related Due to the different lengths of the igniter elements, a variety of additional specifications are required to be distinguished and identified. Frequent specification changes are required 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-leg wire, the high-temperature injection molding process of the bayonet plug will cause the insulation skin of the long-leg wire core to melt, which is easy to form a short circuit and produce unqualified products, and the traditional bayonet plug is made of opaque material , the processing quality inside the bayonet plug cannot be checked and judged conveniently, which brings great uncertainty to the subsequent processing

[0010] 6. In the traditional integrated structure of long foot line and bayonet plug, the length of the bayonet plug is relatively short, and it is inconvenient to take it during on-site operation. security requirements

Utility model patent 202020193388.2 "A Reinforced Electronic Ignition Part and Its Electronic Detonator" discloses a structure of a fully assembled enhanced electronic igniter and its detonator. However, the technical problem of fast and convenient connection is not solved, and the current conventional electronic detonator assembly method is still used.
