IMPACT PROTECTION DEVICE Russian patent published in 2020 - IPC F16F15/20 F16F15/14 H05K5/00 H02K5/24 

FIELD: radio electronics.

SUBSTANCE: invention relates to the field of radioelectronic equipment, in particular, to devices for protection against intensive impact loads. Disclosed is a device for protection against impact effects, comprising: a housing with a hole, at the bottom of which there is equipment in form of a package of printed circuit boards, on the housing bottom eccentrically to its axis there is a cylinder with a hole, on the end of which there is a package of printed-circuit boards, connected to it by a fastening element, made in the form of a truncated cone with cylinders formed on its bases, wherein inner and outer generatrixes of truncated cone are made at different angle to longitudinal axis of fastener, and fastening element is installed in cylinder with formation between inner surface of cylinder and outer surface of truncated cone of gap fastening element. Cylinder of fastening element of smaller diameter has thread. Height of the cylinder at the bottom of housing is 0.45–0.6 of the height of the stack of printed circuit boards, and a hole is made in the cylinder on the bottom of the housing along its axis.

EFFECT: technical result is use of radio electronic equipment without preliminary frequency detuning of its components in limited volumes of compartments of small-size aircraft in a wide range of frequencies of high-intensity actions, with minimum response time of damping properties of structure when considering that high-intensity effects of different nature can coincide at one and the same moment in time.
