RADIOELECTRONIC UNIT CASE Russian patent published in 1996 - IPC

FIELD: radioelectronics. SUBSTANCE: radioelectronic unit case has interconnected back panel , side walls with coaxial openings, and face panel with edges projecting beyond dimensions of the side walls, and fastener unit made in the form of two parallel flat two- arm levers. The levers are interconnected on the side of their proper ends with a transverse bar and their other ends are fastened to openings of opposite walls so that they may be turned about geometric axis of the point where levers and thrust screw are secured. The screw is directed towards face panel from its rear side. The above coaxial openings in the side walls are pear-shaped with lengthwise geometric axes arranged in the same way about each other and placed at 20 - 40 angle to edges of side walls joint to the face panel. Flat levers of fastener unit are two-armed with coaxial mushroom-shaped projections reply to openings in side walls. The transverse bar of the fastener unit has central opening and is perpendicular to surfaces where flat levers are located. The thrust screw is placed in transverse bar opening and oriented with its lengthwise geometric axis towards perpendicular to geometric plane formed by flat levers and transverse bar of the fastener unit. Mushroom- shaped projections of the flat levers are placed in pear- shaped openings of the side walls and may interact to edges of the above openings. Substantially threaded hole for thrust screw is originated in a flat lever of the fastener unit. Circular hole is originated in one side wall placed just opposite to the above lever. EFFECT: high strength. 2 cl, 4 dwg
