Enclosure for electronic equipment and method for manufacturing an electronic equipment enclosure

Abstract

To provide a housing for an electronic device 2 that is easy to assemble and has excellent shielding properties at the connecting portion between a bottom frame 3 and a front panel 4.SOLUTION: A front panel 4 is attached to a housing 2 in the middle of assembly (Fig. 3). The front panel 4 can be attached to a bottom frame 3 by the simple operation of engaging and sliding a long hole 21 of a flange 20 of the front panel onto a protruding member 16 of the bottom frame 3 (Fig. 5), and the housing 2 is completed by covering it with a hoisting drum 8 and fixing it with a fixing screw 29 (Fig. 7). The gap between the flange 20 and the bottom panel 3 is set to the height of a base 17 of the protruding member, such that the amount of crushing of a first shielding material 15 in the gap is constant, and the electromagnetic wave shielding performance in that part is constant.SELECTED DRAWING: Figure 4
