JP2003069240A - Panel structure for housing - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent any clearance from occurring between a decorative panel and a front panel for attaching thereto components, even in the case of a small number of screws. SOLUTION: In a panel structure for housings, a decorative panel 10 is so formed curvedly as to protrude it in its short-side direction toward a front panel 3. Then, it is fastened by screws to a housing main body together with the front panel 3.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel structure of a housing, and more particularly, to a panel structure of a housing suitable for molding an operation surface of an electronic device. 2. Description of the Related Art Many electronic devices are housed in a housing, and an operation switch is provided with an operation switch, a display window of display means, and the like. FIG. 2 is an exploded view showing an example of the structure of the operation surface of such a housing. In general, a front panel 3 for fixing a printed wiring board 2 on which components are mounted, and an external panel mounted outside It has a double structure with the decorative panel 4 that makes necessary screws and the like invisible. The decorative panel 4 is provided with holes for a switch operation unit and a display window similarly to the front panel 3, and the decorative panel 4 and the front panel 3 are fixed to the housing body 1 by screws. [0003] As an example of such a housing structure, for example, a 0.3-m-thick plate is provided between a metal plate requiring grounding and the housing.
Japanese Patent Application Laid-Open No. Hei 10-223392 discloses a structure in which a grounding of an internal circuit is established by interposing a leaf spring member having a curvature of about m to improve workability in assembling. [0004] In the case of the configuration of the operation surface as shown in FIG. 2, it is preferable in terms of appearance that the number of screws for fixing the decorative panel 4 is small. However, for example, if one screw 6 is used at each of the four corners of the decorative panel 4, a gap 5 may be formed between the decorative panel 4 and the front panel 3 as shown in FIG. To prevent this, it is sufficient to increase the number of screws, but this will impair the appearance, reduce the performance of the decorative panel 4 in terms of "makeup", and reduce the workability during assembly and disassembly of the housing. There is a problem to do. An object of the present invention is to provide a panel structure of a housing which does not impair the appearance of an operation surface and has good workability during assembly and disassembly. According to the present invention, there is provided a flat front panel for mounting components arranged inside a housing, and a short side of the front panel is convex toward the front panel. The operation surface is constituted by a double panel with a decorative panel which is formed in a curved shape and is arranged outside the front panel and fixed to the housing body by screwing together with the front panel. A panel structure of a housing is disclosed. An embodiment of the present invention will be described below. FIG. 1 is a development view showing a structural example of an operation surface of a panel structure of a housing according to the present invention. Case body 1, front panel 3
Has the same structure as the conventional FIG. 2, but the decorative panel 10 is curved so that the short side direction (Z direction in the figure) is convex toward the front panel, and the longitudinal direction (X direction in the figure). Has a linear structure. The installation of holes such as an operation switch operation unit and a display window is the same as the conventional one. Such a curvature may be given by, for example, press working following the drilling step to bend, and only one additional working step is required. When the decorative panel 10 is attached to the housing body 1 together with the front panel 3, it is easier to bend in the longitudinal direction than in the lateral direction. For this reason, in the conventional structure, a gap is likely to be formed by screwing at the four corners.
0, bend in the short direction, and screw 6, 6
When the screws are screwed as shown in FIG. 4, the pressure of the screwing causes an elastic force to adhere to the front panel 3 to prevent the bending in the longitudinal direction, so that the gap can be eliminated even with a small number of screws. According to the present invention, the decorative panel can be securely attached even if the number of parts and the number of working steps are small, and the effect of the makeup is not impaired and the working efficiency is improved.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a development view showing a structural example of an operation surface of a panel structure of a housing according to the present invention. FIG. 2 is a development view showing a structural example of an operation surface of a conventional panel structure of a housing. FIG. 3 is an explanatory view of a problem of a conventional housing structure. FIG. 4 is an external view of the structure of FIG. 1 when four corners of a front panel are screwed.
