SUSPENSION FOR ELECTRONIC MODULE TO OPERATE DURING AND AFTER SEVERE IMPACTS

摘要

The present invention relates to a suspension for an electronic module. This suspension comprises at least: - a first rigid structure (2); - a second rigid structure (3), intended to be fixed to the first rigid structure, the first and the second structure forming a cavity (10) once fixed together - one or more shock absorbers (5, 6, 7, 8), intended to be in contact with the surface of said cavity; - a rigid coating (4) of the electronic module (1), intended to be placed in said cavity (10) in contact with the shock absorbers (5, 6, 7, 8) and mechanically decoupled from the cavity, the shock absorbers being prestressed (F) when the first and second structures are fixed together, by the cavity on the one hand and the rigid coating on the other hand, each shock absorber adhering to the rigid coating or to the cavity or to both. The invention is particularly applicable to electronic modules of measuring and recording devices (crash test, airplane black boxes for example), to electronic modules of devices intended to be ejected (micro satellites for example) and to electronic modules ammunition intended to operate after an impact (penetrating ammunition). / P
