Front panel

Abstract

Abstract PURPOSE:To secure the shield of an interfering wave by tightening clamp holes formed in a shelf frame on the tip side of machine screws toward a shelf frame side by the machine screws and shielding the whole opening of the shelf frame by a front panel. CONSTITUTION:When a printed circuit board 2 is mounted to a shelf frame 1, the printed circuit board 2 is sequentially inserted with the guide of rails provided inside the shelf frame 1 and the fulcrum portion 13-1b of a front panel 13 is inserted into an engaging metal 15 with a Z-shaped section which is fixed to the shelf frame 1 on the upper portion of the opening of the shelf frame 1. Further, since the printed circuit board 2 presses a conductive rubber 13-3 on a curved portion against the lower portion of the opening, the printed circuit board 2 is mounted inside the shelf frame 1 by fastening machine screws 14 inserted in clamp holes 13-1c formed on the lower end side of the front panel 13. Thus, the front panel 13 surely shields the front side opening of the shelf frame 1 from an interfering wave and can remove the need of a tool for dismounting the printed circuit board.
