[0002] Electronic detonators, also known as digital electronic detonators, digital detonators or industrial digital electronic detonators, are electric detonators that use electronic control modules to control the detonation process. The electronic control module refers to a dedicated circuit module that is placed inside the digital electronic detonator and has the functions of detonation delay time control and detonation energy control, with a built-in detonator identity information code and detonation password, and can test its own functions and performance as well as the electrical properties of the detonator ignition element, and can communicate with the detonation controller and other external control devices. The detonator plug is a plastic sealing plug that is used to insert into the detonator shell and seal the mouth of the detonator shell; the existing electronic detonator plastic sealing plug is usually composed of a plug body and a detonator wire that runs through the plug body. The existing detonator plugs often become loose and unreliable in sealing, thereby affecting the quality and reliability of the electronic detonator. In view of the above problems, the utility model provides a solution. Utility Model Content
