Description

The present invention relates to a housing structure, and more particularly to a housing structure in which a metal cover having an insulating coating on the outer surface and having a cut surface is attached to a rear cover. .

[Prior Art] In recent years, a decorative steel plate has been used for a housing structure of an electronic device such as a personal computer.

By the way, heretofore, this type of housing structure has been constructed by attaching the cover 20 to the rear cover 30 as shown in FIGS. 6 to 8, for example. The cover 20 is a decorative steel plate having an insulating coating 20a on the outer surface and a cut surface 20b at its end.
Then, the inner surface of the cover 20 is brought into contact with the outer surface of the rear cover 30, and is fixed by the two screws 21 and 21.

[Problems to be Solved] However, in the above-described conventional housing structure, since the inner surface of the cover 20 is simply brought into contact with the outer surface of the rear cover 30, the cut surface 20b appears at the end portion of the cover 20, and the appearance of the cover 20 is reduced. Therefore, there is a problem in that a work process of coating with the same color as the insulating film 20a of the cover 20 is required, resulting in a high price.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a housing structure that can be manufactured at low cost without the need for coating the cut surface with the same color as the insulating coating. .

[Means for Solving Problems] Therefore, in the present invention, in the housing structure in which the metal cover formed in a U shape having the insulating coating on the outer surface and the cut surface is attached to the rear cover, The cover is formed by bending one end portion having the cut surface until the inner side surfaces come into contact with each other, and the end surface portion having the insulating coating on the outer side surface, and after forming the end surface portion, the one end portion is bent vertically. And a mounting portion provided with a cutout portion, the cutout surface being in contact with the outer surface of the rear cover and the inner surface of the mounting portion being in contact with the outer surface of the rear cover. It is intended to achieve the above object by adopting a configuration in which the cover is fastened and fixed to the rear cover with a screw via a portion.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

The housing structure of the present embodiment has a cover 1 attached to a rear cover 10.

The cover 1 is a decorative steel plate, which has an insulating coating 1a on the outer surface and a cut surface 1b, and has a U-shape. Further, an end surface portion 2 having an insulating coating 1a is provided at one end of the cover 1b. The end surface portion 2 is formed by bending the end portion of the cover 1 on the side of the cut surface 1b until the inner surfaces come into contact with each other.

On the cut surface 1b side of the cover 1, a mounting piece 3 is integrally formed with the cover 1.
Is provided. The mounting piece 3 is formed by bending the end surface portion 2 and then bending it to a vertical position. Further, the mounting piece 3 is formed with a notch 3a for inserting a screw.

The cover 1 has the opening side fitted in the rear cover 10, the cut surface 1b is in contact with the outer surface 10a of the rear cover 10, and the inner surface of the mounting piece 3 is in contact with the outer surface 10a of the rear cover 10.

Then, the screw 4 is screwed into a screw hole formed in the rear cover 10 through the cutout portion 3a of the mounting piece 3 so as to be fixed to the rear cover 10.

As described above, according to the present embodiment, the cut surface of the cover 1
Bend the end on the 1b side to cover the end of the cover 1 with the insulating film 1a.
Since the end surface portion 2 having the shape is formed and the cut surface 1b is in contact with the outer surface of the rear cover 10, the cut surface 1b cannot be visually recognized from the outside and the appearance is improved.

[Advantage of the Invention] As described above, according to the present invention, one end portion having a cut surface of the cover is bent until the inner side surfaces come into contact with each other to form an end surface portion having an insulating coating on the outer surface, and the cut surface is formed. Since the cover is fixed to the rear cover while being in contact with the outer surface of the rear cover, it becomes impossible to visually recognize the cut surface from the outside, and as a result, the painting process performed on the cut surface can be omitted and the cost can be reduced. It is possible to manufacture the housing.

Furthermore, in the present invention, the cover is formed by bending the one end vertically after forming the end face portion, and the cover is fastened and fixed to the rear cover with the screw through the mounting portion having the cutout portion. Since it can be fixed to the rear cover and the thickness of one end of the cover can be reduced, the mounting area inside the housing can be increased.
