CONTACT ELECTRONIC FUSE TO ARTILLERY AMMUNITION Russian patent published in 2019 - IPC F42C1/00 F42C11/06 

FIELD: military equipment.

SUBSTANCE: invention relates to military equipment. Contact electronic fuse to artillery ammunition consists of metal housing, in upper part of which there is pyrotechnic source of electric current with electronic control system. Control circuit comprises in-series connected to the electric current source a first diode, a second diode, a resistance, an external mode switch, a delay line, an inertial contact group and an electric igniter, between which, parallel to the electric igniter, an actuating capacitor and a second capacitor are connected. In the middle part of the fuse housing there is a protection device with a mechanical inertial contact group, an electric igniter connected to an actuating capacitor, a transfer charge, moving screen located between electric igniter and transfer charge. Moving screen in initial state is fixed by pyro-support. Protection device also includes an inertia pyrotechnic cap-igniter with movable pyrotechnic element, having holes in its housing, namely, one in contact area with pyro-support and second one in upper part in contact zone with inlet hole of pyrotechnic source of electric current. In lower part of fuse there is detonator. Transfer charge is arranged above detonator. Electronic control circuit incorporates delay device with external switch. Elements of electronic control circuit are fixed with fast-hardening plastic.

EFFECT: invention can be used in development and manufacture of fuses for artillery ammunition.
