ABSTRACT:
An electric initiator, such as a detonator, primer or squib, has a plastic case, a metallic inner cup, an explosive charge and a coaxial plug assembly which includes a conductive pin, a conductive sleeve surrounding the pin and spaced therefrom, an insulator which is bonded to both the pin and the sleeve, and a bridge wire connecting the two electrodes. The initiator also includes two lead wires, one welded or soldered to each electrode. This initiator is easy to assemble automatically and is highly resistant to accidental firing by static electricity.
