RADIO-ELECTRONIC UNIT Russian patent published in 2002 - IPC

FIELD: radio-electronic engineering; package-type units for multichannel communication systems, computers, and check-up systems. SUBSTANCE: unit has packaged printed-circuit boards with adjacent contact pads insulated from each other on face and rear sides of boards, connectors in the form of insulating blocks with spring contacts disposed between printed-circuit boards and engageable with mentioned contact pads, and terminal members of package; contact pads are made in depressions of printed-circuit boards provided with coaxial metallized transfer holes and coated with plastic electricity conducting layer with two to four embedded S-shaped spring contacts which are press-fitted into insulating blocks and are sequentially coming in contact; surface holding each contact is perpendicular to face and rear sides of board. At least one of connectors may be provided with additional contact surface brought out onto one of external sides of unit. Every second contact may be arranged so that together with first one it will form S-shaped contact member. Each lid of radio-electronic unit may be provided with at least one respective connector each of whose pin contacts terminates in contact pad engageable with spring contact, or else each pin contact terminates in spring contact member engageable with contact pad of printed-circuit board. EFFECT: facilitated manufacture of spring contacts; enhanced reliability and reduced size of unit. 5 cl, 8 dwg
