Abstract:
1. A printed circuit board supporting structure comprising: a printed circuit board; a board support constituted by a conductor; and a clamping device that clamps and fixes the printed circuit board to the board support, a solder bump pattern provided on a board surface of the printed circuit board being brought into contact with an obverse surface of the board support at a portion clamped by the clamping device to electrically conduct with the board support, wherein the clamping device is a headed clamp screw, the solder bump pattern being provided around a periphery of a screw insertion hole provided in a corner portion of the printed circuit board, a cantilevered supporting piece having a reference supporting surface for restricting a reference position of the printed circuit board being provided integrally with the board support constituted by a chassis, a cantilevered clamping piece formed by punching the supporting piece being disposed on a lower side of the supporting piece, the supporting piece being provided with a reinforcing rib to reinforce the supporting piece, a recessed notched portion being provided in a root portion of the clamping piece to narrow an effective width of the root portion, and deformation resistance strength of the clamping piece is made weaker than the deformation resistance strength of the supporting piece, and wherein the headed clamp screw inserted in the screw insertion hole of the printed circuit board in which a periphery of a portion where the solder bump pattern is formed is placed on the reference supporting surface is inserted and tightened in a threaded hole provided in the clamping piece, and the clamping piece is deformably brought into pressure contact with the solder bump pattern disposed through an opening, which is formed as a punched space of the clamping piece formed in the supporting piece, by means of a tightening force thereof.
