Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box structure of an electronic device such as a telephone exchange device.

[0002]

2. Description of the Related Art A conventional telephone exchange device has a casing structure in which columns are provided at four corners of a bottom plate, a top plate is provided above the columns, and four side plates are provided on the columns. Form the body appearance. Further, shelves for accommodating electronic packages are provided in multiple stages in the upper direction inside the pillars, and form the basic structure of the housing.

Further, Japanese Utility Model Laid-Open No. 62-199984 discloses a structure of a multistage stacking housing, in which so-called building block type electronic device housings can be stacked and fixed from the front side.

[0004]

As described above, the conventional telephone exchanging apparatus casing structure is not easy to assemble because the columns and the like are mainly fixed by welding. In recent years, environmental issues have been discussed, and there are cases in which manufacturers collect products. Therefore, fixing by welding has a problem that separation is not good and it is difficult to discard.

The present invention solves the above-mentioned problems, and an object of the present invention is to improve the assemblability and separability and to facilitate the construction of a building block. To provide.

[0006]

In order to achieve the above-mentioned object, the present invention has a bottom plate having a claw, a slit fixed to the bottom plate with a screw for inserting the claw, and a side surface. An L-shaped side plate covering the back surface, a support plate fixed to each of the bottom plate and the L-shaped side plate with a screw, a beam fixed to the side surface of the L-shaped side plate and the support plate with a screw, and the L-shaped side plate. And a partition plate fixed to the side plate and the support plate with screws and also serving as a back wiring board attachment, and a partition plate fixed to the rear plate with screws and fixed to the bottom plate. And

[0007]

With this structure, the vertical load is supported by the L-shaped side plate, the support plate and the bottom plate, and the horizontal load fixes the bottom plate, the L-shaped side plate and the support plate, and the bottom plate and the L-shaped side plate. It is supported by the screws and the insertion portions of the support plate and the bottom plate, and the load in the depth direction is supported by the screw fixing portions and the insertion portions of the bottom plate and the L-shaped side plate and the screw fixing portions of the support plate and the bottom plate. This makes it possible to withstand loads and vibrations on all sides without welding the connections between the components.
