Description

Technical Field

[0001] This invention relates to the technical field of blasting tools, specifically to a multi-identification pairing electronic detonator and its identification and pairing method. Background Technology

[0002] Detonators are the main initiating material in blasting engineering. Their function is to generate initiation energy to detonate various explosives, detonating cords, and detonating tubes. Detonators are divided into two types: ordinary detonators and digital electronic detonators. Among them, digital electronic detonators are the most widely used because they use electronic control modules to control the initiation process and have functions such as detonation delay time control and initiation energy control. For example, patent number CN201920267001.0 discloses a plug-in type digital electronic detonator. Through the plug-in design, the conductive wire and the detonator part can be separated, thereby realizing the convenience of production, packaging, and transportation, and further ensuring safety during transportation, storage, and use. However, it still has the following problems: 1. To ensure the safety of use, the existing pairing identification method is to identify the tube sleeve and the detonator part through serial number tags. However, since the tube sleeve and the detonator part adopt a butt joint connection, the tube sleeve can be used to connect other types of detonator parts. The serial number tag identification method has the following problems: 1. Existing plug-in digital electronic detonators have several drawbacks. Firstly, they lack a locking mechanism, leading to potential safety issues and posing a safety hazard to detonator manufacturers. Secondly, the lack of a locking mechanism results in unstable connections between the tube sleeve and the detonator, affecting subsequent electrical connections and overall performance. Thirdly, the absence of a warning function makes it difficult to identify the connection points in low-light conditions, hindering installation efficiency. Fourthly, the lack of dust protection allows dust to easily accumulate at the tube terminals, causing blockages and affecting pin connections. Furthermore, the absence of a reinforced electrical contact structure increases the risk of poor contact between the tube terminals and pins, further compromising usability. Summary of the Invention

This requires both mechanical and electronic identification. The dual identification pairing of the components enables electrical conductivity between the detonator and the sleeve, ensuring that the sleeve can only be used with detonators possessing the corresponding identification structure. This improves safety and facilitates subsequent tracing of the detonator's origin and distribution channels. The detachable structure facilitates quick alignment and locking between the detonator and sleeve, enhancing installation efficiency and stability. The inclusion of indicator components provides fluorescent guidance, aiding in accurate alignment and location of the connection point in low-light conditions, further improving connection efficiency.
