DEVICE AND METHOD FOR PROTECTION OF RADIO-ELECTRONIC BLOCK AGAINST ACTION OF CRITICAL MECHANICAL SHOCK Russian patent published in 2009 - IPC H05K5/06 

FIELD: physics.

SUBSTANCE: device for protection of radio-electronic block contains case with the basis and lateral walls in which grooves are executed. Printed-circuit boards are mounted on the basis of the case in the form of structural sphere. H-shaped basis is located in the case. Lateral walls are represented by two hemispheres with carving in joint places. Each stratum of the case consists of two lateral walls - hemispheres with displaced centre of gravity which are located uniformly in the case. In the combined grooves of all stratums windows for cooling of the block are generated and-or cables for exterior electrical communication are disposed. The expedient for protection of the radio-electronic block provides transformation of energy of shock to energy of circumrotatory motion of each stratum at the expense of displaced centre of gravity of stratums. At the moment of shock there is an edge of plug and a cable of the block at the expense of arrangement of centre of masses of each stratum in various points and gyrations of each stratum of the block on determinate direction.

EFFECT: increase of protection efficiency of radio-electronic block from action of electromagnetic noises, increase of shock strength at action on the radio-electronic block of critical mechanical shock that is reached at the expense of transformation to the block of energy of shock in energy of circumrotatory motion.
