RADIO-ELECTRONIC BLOCK Russian patent published in 2006 - IPC H05K1/00 H05K5/03 H05K7/12 

FIELD: radio engineering, possible use for engineering of small-dimension screened radio-electronic equipment blocks.

SUBSTANCE: radio-electronic block has frontal and back panels made of electro-conductive materials and upper and lower lids connected thereto, and also an electronic board, positioned in the inner space of radio-electronic block, carrying electronic nodes and connected to one of panels and lower lid. Upper and lower lids are made U-shaped and connected to each other through side engagement straps, made of electro-conductive material, in upper and lower grooves of which side edges of respectively upper and lower lids are held, and in side grooves - side edges of electronic board. End edges of lids and end shelves of engagement straps are positioned in grooves, made on inner side of frontal and back panels. Along bottom of aforementioned grooves and also along bottom of upper and lower grooves of side engagement straps, portions of electro-conductive elastic wire are positioned, providing for compensation of mechanical gaps and electric contact between lids, side engagement straps and panels at portions of their connection. Panels are held tight to side engagement straps by screw couplings, as which screws are used, inserted from external sides of both panels into threaded apertures, made on ends of both engagement straps.

EFFECT: possible production of radio-electronic block, wherein guaranteed electrical contact is provided for all engagement lines of connected elements, forming external protective screening cover of radio-electronic block, with simultaneously decreased amount of external holding elements, connecting them in form of a single mono-block construction.
