[0002] The electronic detonator comprises a foot line, a control circuit board with a delay chip, an ignition head and explosive in sequence. When in use, the busbar used to output the detonation signal is connected to the foot line, and then the detonation serial signal is output. The delay chip delays for a preset time, and then the control circuit board transmits the detonation signal to the ignition head through a bridge wire to realize detonation control.

[0003] In the mass production process of existing electronic detonators, the end of the leg wire extending out of the electronic detonator is generally exposed, which is not only not tensile-resistant, but also inconvenient, time-consuming and unreliable to connect at the blasting site. It is also easy to come into contact with static electricity and cause the detonator to explode accidentally, which also poses a safety hazard.

[0004] Therefore, in view of the shortcomings of the prior art, it is necessary to provide a decomposable shaft-type wire clamp structure for an electronic leg wire to solve the shortcomings of the prior art. Utility Model Content
