Description

Technical Field

[0001] The invention relates to the technical field of civil explosives, in particular to a water-resistant two-compartment tail wire clamp. Background Art

[0002] Electronic detonators are a type of civil explosive used in industries such as engineering construction and mining. Currently, they are commonly used in civilian blasting. The rear of an electronic detonator is connected to a detonator chip and a tail wire. The detonator chips of multiple electronic detonators are connected to the electrical busbar via the tail wire. The detonator chip has a built-in trigger program. When detonation is required, a specific electrical signal is sent through the electrical busbar, and the electrical signal is input into the detonator chip via the tail wire. When the electrical signal matches the trigger program, the detonator chip is triggered, thereby detonating the electronic detonator. Therefore, the tail wire clamp that connects the tail wire to the busbar is an indispensable component of electronic detonators. Convenience and waterproofness are important parameters for evaluating their safety and practicality. They provide a basic guarantee for convenient networking and safe detonation control of electronic detonators in engineering blasting. Existing electronic detonator tail wire clamps are single-compartment type and are not effectively waterproof. When electronic detonator blasting operations are carried out in wet and humid environments, water immersion often causes the wires to short-circuit, increasing the current and voltage and resulting in serious safety hazards such as failure to detonate and premature detonation.
