Zusammenfassung: | FIELD: production of an electric means of initiation. ^ SUBSTANCE: the invention is pertaining to the electric means of initiation and may be used in a means of ignition of the powder and pyrotechnic charges of fireworks and a means of fire fighting automatics. On a skeleton made out of a foil-clad glass fiber laminate using the method of optical lithography and a selective etching there are the copper inner electrodes with the metallized through holes. On the side of the skeleton a fuse head is soldered, and on the other side there are outside electrodes soldered in the metallized through holes. The fuse head is spaced from a butt of the skeleton by (0.l-0.3)L, where L is a length of the skeleton. The explosive charge with a binding agent is applied on the both legs of a hackberry on a length (O, 3-O, 5) L. The whole surface of the charge is phlegmatized, i.e. is coated with an armoring layer of a varnish or a compound. The technical result consists in an increased reliability of a product and a decreased blasting effect of the charge actuation. ^ EFFECT: the invention ensures an increased reliability of a product and a decreased blasting effect of the charge actuation. ^ 2 dwg |
