FIELD: engineering of electronic equipment, possible use for accommodating a screened circuit. ^ SUBSTANCE: case for electronic devices contains component parts in form of spheroid consistent closed surface with radius and center, mounted inside which are units and blocks in form of parallelepiped, and having screening properties due to usage of multi-layer screens made of combination of magnetic and non-magnetic layers with low specific electric resistance, with current-conducting cover, presence of several surface separation boundaries in screens, on each one of which reflection of electromagnetic wave occurs, having isotropic radiation and dissipation of falling electromagnetic waves due to curvature of surface and having circular directional diagram in any plane, surfaces of component parts being made in form of spheroid of alternating radius and alternating center with smooth mating of component parts, with shape close to parallelepiped, and electric connector is formed: internal ones - socket part, external ones - fork part, component parts are made with possible automatic detention by internal surface of next layer of internal surface of prior layer, forming electric contact, profile dimensions of which match one another, in each layer component parts by ends are connected across inclined surface, forming an unipolar electric connector, while each layer relatively to previous layer is positioned perpendicularly to mating line, while the last layer is held by screws, connection axes of which across mutually opposite sides are positioned perpendicularly to mating line of the last layer, by means of threaded bushings in first layer through remaining layers. ^ EFFECT: efficient usage of internal space of case, preservation of screening properties and simplified assembly-disassembly of case. ^ 4 dwg |
