초록

Electroexplosive device and static discharge element therefor. The electroexplosive device herein has a cylindrical metallic casing which is open at one end and closed at the other end, a bridge element and lead wires therefor, a static discharge disc surrounding the lead wires for preventing accidental ignition due to static electricity, and a ferrite sleeve surrounding the lead wires to prevent accidental initiation due to radio frequency currents. The static discharge element comprises a nonconductive circular substrate having a slotted opening for th...
