WIRING UNIT (VERSIONS) AND METHOD OF ITS MANUFACTURING (VERSIONS), UNIT OF ELECTROTECHNICAL EQUIPMENT AND METHODS OF MANUFACTURING AND REPAIR Russian patent published in 2010 - IPC H05K1/14 H05K3/36 H05K5/00 H05K7/10 H05K13/06 

FIELD: radio engineering.

SUBSTANCE: wiring unit comprises printed circuit boards and multiserial sockets installed on their ends, besides printed circuit boards are installed between rows of socket contacts parallel to each other so that in the first version one of boards with its end sides is electrically connected along one and another surface accordingly with one and another neighbouring rows of socket contacts, and another and subsequent boards with their end sides are electrically connected along outer surface accordingly with other subsequent rows of socket contacts; in the second version - each board with its one end side is electrically connected along one and another surface accordingly to neighbouring rows of opposite sockets contacts, and with its other end side it is electrically connected along external surface accordingly to outer row of opposite sockets contacts. Unit of electrical equipment comprises packet of wiring units made of printed circuit boards with sockets installed on their ends fixed by pair fastening panels. Methods are also proposed to manufacture wiring unit and unit of electrotechnical equipment. Method for repair of electrical equipment unit, in which in packet of wiring unit they detect faulty wiring unit, packet fixtures are removed, due to rotation of units access is provided to faulty piece, fault is eliminated, and packet of units is returned into initial position, consists in the fact that in packet of wiring units arranged with sockets, to which at least printed circuit boards are connected electrically, and boards along their single identical side through holes-contacts are pierced mainly with rigid single-core electric wires, fastening panels are removed from wiring units, faulty unit is detected, and packet of wiring units is divided into two parts relative to it, other units are turned due to bending of wires in different sides to obtain required access to faulty board of unit, after elimination of fault units and fastening panels are put back in place.

EFFECT: high technological properties, low metal intensity, high rigidity and strength characteristics, good repairability and wide opportunities in building of universal units and blocks of various purpose.
