INITIATING MEANS Russian patent published in 1999 - IPC

FIELD: production of initiating means of high-explosive charges, applicable in production of detonators. SUBSTANCE: initiating means uses a primer detonator, electric primer, winding on a ferrite ring located in an insulating bush with a through hole to pass the primary circuit. The hole is made parallel with the primer- detonator sleeve and with a shift exceeding the sleeve radius. The insulating bush has a boss whose height exceeds the diameter of the primary circuit wire. Variants of initiating means differ by employment of a clamping sleeve on wires, their moulding, as well as by marking of different kinds. EFFECT: reduced labour content of manufacture, improved electric characteristics of detonator and enhanced adaptability to manufacture. 5 cl, 3 dwg
