摘要
Circuit boards are locked in operation parallel with each other in a U-shaped housing frame. In case of fault they can be connected - without removal of connectors - for fault detection and/or repair, by a ribbon cable or by individual cables. Each circuit board (3) is held by two parallel edges in board holders (4) with pins (6-8) projecting outwards parallel to the board, and in pairs in line with each other. They serve as guiding pins (6) near one of the board corners, and can rotate in holes in parallel sides (2) of the housing frame (1), or as locking pins (7) lockable in one of two positions in further recesses (10) of the frame sides, so that the circuit board can swing out from the housing frame. The edge near the board swining axis carries the connector (13) for supply of signals and voltages.
