VOLUME MODULE FOR RADIO ELECTRONICS EQUIPMENT Russian patent published in 2012 - IPC H01L25/16 

FIELD: radio engineering.

SUBSTANCE: in a volume module for radio electronics equipment having a rigid structure with leads, placed into a metal body and filled with a compound, comprising electrically and mechanically joined rectangular printed circuit boards with screening layers and installed radio electronic components, two of them are arranged horizontally, the other ones - vertically, and forming with their faces (including end ones) contours of a volume figure symmetrical relative to at least two of symmetry planes stretching via a vertical axis of the module, besides, the upper horizontal board lies not below the level of upper end faces of all vertical boards, and the lower one - not higher than the level of the lower end faces of these boards, and has external leads being leads of the module, each vertical printed circuit board comprises two separate halves of the same height, which are in planes stretching via a vertical axis of the module, and one of end side faces of each half is to the maximum brought near and parallel to this axis, and lying in a mirror manner symmetrically relative to the specified planes of symmetry or a vertical axis of the module, besides, an orthogonal projection of the upper or lower end face of any larger or smaller half at least at one of symmetry planes is within the contour of the horizontal boards, and contain contact sites along the upper and lower sides, horizontal boards have the shape of a circle with a centre lying on the axis of the module, on the contour of which there are ends of projections to this circle of smaller halves of vertical boards, besides, the specified contact sites are grouped near the circuit of accordingly upper and lower horizontal boards, where responsive contact sites are located, there are additional printed circuit boards are introduced. At the same time halves of any vertical printed circuit board may be in the same plane. Larger halves of vertical printed circuit boards may have length equal to length of smaller halves.

EFFECT: development of a volume module for radio electronics equipment with reduced dimensions at lower labour intensiveness of manufacturing, proper noise immunity and repairability.
