Compact electric detonator with built-in electromagnetic interference (emi) filter and method of assembling the same

A method of assembling a compact electric detonator with a built-in electromagnetic interference (EMI) filter, the method comprising:

• protruding one ends of a first lead wire and a second lead wire beyond a lower surface of a glass bead and extending the first and second lead wires to a bottom surface of the spacer;
• connecting a heating wire to the one ends of the first lead wire and the second lead wire;
• sequentially inserting a buffer plate and an EMI filter into the other side of the glass bead to complete a plug assembly;
• inserting the plug assembly into the cup;
• and
• applying an adhesive to a gap between an end of the plug assembly and the other ends of the first lead wire and the second lead wire and fixedly bonding the plug assembly and the first and second lead wires.
