FIELD: shock-proof unit for electronic circuit, in particular, for explosive devices. SUBSTANCE: the electronic circuit is enclosed in a capsule, which is contact with the body surrounding it and dissipating the energy of impact. The capsule may have a great number of ribs, plates or bosses, which rest against the body. The capsule may include a material absorbing the impacts and positioned near the body for protection of the circuit against vibrations, and a constructional supporting material, for example, in the form of a casing for protection of the circuit against the mechanical stress. The unit for the circuit may be a part of the initiation unit enclosed in a shell, the unit includes a transmitting element for transformation of the energy of shock wave to electric energy for the electronic circuit, and the released energy may be transformed to a signal of detonation initiation. The unit may serve as part of the detonator, which receives the electric signal of initiation and causes detonation after a delay determined by the electronic circuit. The detonator enclosure or (not obligatory) the bushing may include one or more inserts, for example, O-shaped rings positioned around the casing for the circuit. EFFECT: enhanced precision of detonator actuation. 25 cl, 14 dwg
