Title: Electronic apparatus with heat radiating plate
Inventor: MASUMOTO NAOKI
IPC: H05K7/14
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To protect a printed circuit board from damage caused by shock of fall, by providing a rib projected downward from an upper inner face of a case body in a way that the rib is near to and opposite to a side part of a heat radiating plate. SOLUTION: Ribs 6A and 6B are projected downward from an upper inner face of a case body 1 in a way that the ribs 6A and 6B are near to and opposite to each side part of radiating plates 4A and 4B. A printed circuit board 2 is bent when force of shock caused by fall is applied, but the side face of heat radiating plates 4A and 4B mounted on the printed circuit board 2 are fitted at the ribs 6A and 6B halfway. Then, the bending of the printed circuit board 2 is limited. On the other hand, since the printed circuit board 2 is bent until the side part is fitted to the ribs 6a and 6B, the force of shock is absorbed by the movement of bending. In this way, a rate of bent of the printed circuit board 2 is limited, while the force of shock is absorbed by the bent and concentration of stress is reduced in the printed circuit board 2.
