Abstract

PURPOSE:To reduce a manufacturing cost and to improve a working efficiency by covering an opening with a protective board which is always united into one body and opening a hole at a root part of said protective board and further arranging a V-shaped cut of lateral direction at a root part of body sides of said hole. CONSTITUTION:On a box wall 6b of a box 6 fabricated with a combination of five sheets of box walls 6a-6e, a opening 7 is arranged. Also in the opening 7, a protective board 8 is formed unitedly to extend from a bottom side of the opening. At a root part of this protective board 8, a hole 8a is formed and at root parts on both sides of the hole 8a, a V-shaped cut 8b is formed in lateral direction so that it can be cut easily. When other components are attached by utilizing the opening 7, the protective board 8 can be bent innerward to be removed easily without using a tool. Thus, there is no need of arranging another protective board and a cost for that can be cut off.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a metal casing.

2. Description of the Related Art A conventional metal casing is shown in FIGS. 6 and 7. Reference numeral 1 denotes a metal casing formed by a combination of five casing walls 18 to 1e, and the casing wall 1b has an opening for inserting components. 2 and a screw hole 3 are provided. 4 is a protection plate, which is attached to the opening 2 by inserting a screw 5 into the screw hole 3 as shown in FIG. 7 when no parts are inserted.

Problems to be Solved by the Invention In such a conventional configuration, the protection plate 4 must be manufactured as a separate component and must also be attached using the bushings 5. Furthermore, the protective plate 4 must be removed when inserting components. In other words, since the protective plate 4 is required as a separate component, the cost is high, and furthermore, the installation using the screws 5 is required, resulting in poor work efficiency.

The present invention is intended to solve these problems, and aims to reduce costs and improve work efficiency.

Means for Solving the Problems and In order to achieve this object, the present invention forms an opening in the wall surface of the housing, provides a protective plate extending integrally from one side of the opening, and An opening is provided at the base of the protective plate, and at the base of the protective plate on the left and right of this opening,
V academic ability in the left and right direction.

Effects According to the above structure, the opening is always covered by the integrated protection plate, so there is no need to provide a separate protection plate, which reduces the cost. Since the opening is provided in the hole and V-shaped cuts in the left and right directions are provided at the left and right bases of the opening, it can be easily removed without using any tools, resulting in good work efficiency.

Example An embodiment of the present invention will be described using FIGS. 1 to 6.

Reference numeral 6 in FIG. 1 is a housing formed by a combination of five housing walls 6a to 6e, and an opening 7 is provided in the housing wall 6b as shown in FIG. A protection plate 8 is formed inside the opening 7 and extends integrally from the lower side thereof. An opening 8a is provided at the base of this protective plate 8, and V-shaped cuts 8b are provided at the left and right bases of this opening 8a for easy cutting as shown in FIG. It is being

In the above configuration, the protective plate 8 that covers the opening 7 is integrally molded with the housing wall surface 6b, so there is no need to make it separately, which reduces costs, and does not require any installation work, improving work efficiency. It will be good.

In addition, in order to attach other parts using the opening 7, the fourth
If the protection plate 8 is bent inward as shown by the broken line in the figure, it can be easily removed without using any tools, which also improves work efficiency.

In addition, since the opening 8a is formed, the above-mentioned removal can be easily performed, and there are fewer burrs 8b remaining in the opening 7.
This also facilitates component insertion.

Note that the burr 8b will not interfere with the attachment of parts to the opening 7 if the lower side of the opening 7a is stepped by the dimension shown in FIG.

Effects of the Invention As described above, according to the present invention, since the opening is always covered with an integrated protective plate, there is no need to provide a separate protective plate, which reduces costs. There is an opening at the base of this protective plate, and a 7-shaped cuff in the left and right directions at the base of the left and right of the opening, so it can be easily removed without using tools and has high work efficiency. Become.
