The utility model discloses a trace initiating explosive industry electric cap, mainly by novel capsule, a powder charge, the cap is strengthened in two times powder charges, the initiating explosive, the body of postponing, electric priming head constitutes. Its characterized in that: interior platform is established to novel capsule inner wall, forms internal diameter big -end -up's special tube structure, strengthen the reverse pressure equipment of cap to interior platform, pressure equipment trace initiating explosive in its " concave " type structure, in this kind of structure, the initiating explosive power is strengthened, is enlargied, and micro - initiating explosive can reach the same effect of initiating explosive quantity on current phase. The utility model discloses a novel capsule and loaded constitution when guaranteeing detonator initiating power, reduce the quantity of initiating explosive by a wide margin, have improved the safety in production rank, have reduced the pollution, have reduced the manufacturing cost of enterprise, have solved waste water and have handled the difficult problem difficult, that the expense is high, have the production technology simple and convenient, with low costs, pollute little, harm is little, the strong advantage of acting output capability.
