The sealing plug is used to seal the wire by injection molding, and has the following requirements: no short circuit should occur between the leg wires; when a certain static tensile force is applied, the leg wire and the sealing plug should not be visually damaged or displaced. Therefore, in the processing of the leg wire of the electronic detonator, in order to enhance the tensile strength of the sealing plug of the electronic detonator, the core wire of the leg wire needs to be twisted before the electronic detonator is injection molded to allow the core wire of the leg wire to be bent.
