Moreover, the mounting of the panel 4 and the chassis 2 and the mounting of the chassis 2 and the case 8 have to be performed separately, and the work efficiency is also poor in this respect. Further, since separate screws are used for attaching the chassis 2 and the panel 4 and for attaching the chassis 2 and the case 8, there are many screw fixing points, and the work efficiency is also poor from this point. .

An object of the present invention is to provide a housing which can improve the work efficiency of assembly.

[0006]

The housing according to the present invention has a flat chassis. As the shape of the chassis, various shapes such as a rectangular shape and a polygonal shape can be used. The rear surface side of the panel is in contact with the peripheral surface of the chassis, and the panel is arranged in a standing state with respect to the chassis. The chassis and the panel are connected by a connecting means. In the coupling means, the fixed wall rises from the upper surface of the chassis and is arranged non-parallel to the panel. The rod-shaped portion is inserted and fixed in the fixed wall, and the tip end of the rod-shaped portion projects from the fixed wall. The restraint portion extends beyond the rod-shaped portion from the back surface side of the panel. The restraint part is
It has a cutout portion into which the tip portion of the rod-shaped portion enters. The cutout portion has a contact surface that comes into contact with the rod-shaped portion when the panel tries to move in the front and back directions thereof.

In this case, when the tip of the rod-shaped portion inserted through and fixed to the fixed wall enters the cutout portion and the panel tries to move in the front and back directions, the rod-shaped portion contacts the contact surface of the cutout portion. It makes contact and restrains the movement of the panel in the front and back directions. That is, the panel is fixed to the chassis in the front-back direction.

Further, the restraint portion may have an upper surface parallel to the chassis. In this case, the chassis has an abutting portion that comes into contact with the upper surface of the restraint portion. It is desirable that the distance between the contact portion and the chassis be selected so that the restraint portion substantially contacts each other.

With this structure, the restraint portion is located between the chassis and the contact portion, and restrains the vertical movement of the panel provided with the restraint portion. Therefore, the panel is fixed to the chassis by restraining its movement in the vertical and front / back directions. All that is required to do this work is to insert the restraint between the chassis and the abutment, and insert the rod into the restraint so that the rod enters the notch. Therefore, it is not necessary to turn over the chassis and the like, and the work efficiency can be improved.

Alternatively, the fixed wall may be formed on a peripheral portion of the chassis. In this case, the rod-shaped portion is a screw, and the screw penetrates a side wall located outside the fixed wall of the case that covers the chassis, and couples the case to the fixed wall.

According to this structure, the common screw can be used to connect the case to the chassis and the panel to the chassis at the same time, which improves work efficiency and is necessary. The number of parts can be reduced. In this case, if the abutment portion is provided on the chassis as described above, and the restraint portion is positioned between the abutment portion and the chassis to restrain the vertical movement of the panel, the panel and the chassis are more firmly fixed. You can combine with.

Alternatively, the fixed wall may be formed on the peripheral portion of the chassis as described above, and the rod-shaped portion may be arranged so that the tip portion is located on the upper surface side of the chassis. That is, the tip portion is located above the chassis from around the chassis. In this case, the restraint portion is located on the lower side of the panel, that is, at a position closer to the chassis, and the first attachment portion that is substantially parallel to the upper surface of the chassis is provided on the upper side of the rear surface side of the panel. The fixed wall is provided with a second mounting portion that makes surface contact with the first mounting portion. The second mounting portion is substantially parallel to the chassis. The first and second mounting portions are connected to each other by a second screw that penetrates both of them and has a tip end facing the chassis.

In this structure, the rod-shaped portion and the notch portion restrain the movement of the panel in the front-back direction, and the first and second mounting portions are connected by the screw, so that the panel is formed. Is constrained from moving up and down.
Therefore, the panel can be coupled to the chassis. Moreover, this connection can be performed by inserting and fixing the rod-shaped portion from the peripheral surface of the chassis into the restraint portion and inserting the screws into the first and second attachment portions from above, and it is necessary to turn the chassis or the like inside out. It is possible to improve work efficiency. In addition, the rod-shaped portion is a screw, similar to the above,
If this screw penetrates the side wall of the case and is connected to the fixed wall, the case can be fixed to the chassis and the movement of the panel in the front-back direction can be restricted by the common screw, and the number of parts can be reduced. .

Further, in the case according to the present invention, fixed walls are provided on two opposing side edges of the flat chassis. The panel is arranged on one of the two side edges of the chassis that are orthogonal to the two opposite side edges. A notch portion is formed in a notch forming portion that is formed integrally with the panel on the back surface side of the panel so as to approach the chassis and faces each of the fixed walls. A rod-shaped member is inserted into and fixed to each of the fixed walls, and a tip portion of the rod member is inserted into each of the cutout portions. The cutout portion has a restraint surface that restrains the movement of the rod-shaped portion in the front-back direction of the panel.
A first mounting surface is formed on the back surface of the panel substantially parallel to the chassis so as to be located near the fixed walls above the back surface of the panel. A second mounting surface is formed on each of the fixed walls substantially parallel to the chassis so as to make surface contact with the first mounting surface. Screws are inserted into the first and second mounting surfaces from above to connect them.

In the case constructed as described above, the rod-shaped member and the notch restrain the movement of the panel in the front and back directions, and
The second mounting surface and the screw restrain the vertical movement of the panel. Also, the movement of the panel in the length direction is 2
Two bar members are restrained. Therefore, the panel and the chassis are securely connected. This connection is made by inserting the rod-shaped member from the peripheral edge of the chassis, and by using the screws.
Since it is only connecting the mounting surfaces of, it is not necessary to turn over the chassis etc. and the work efficiency is improved.

The rod-shaped member may be a screw. In this case, the screws fix the case that covers the chassis to the fixed walls.

In the case of such a construction, the screw which is a rod-shaped portion also connects the case to the chassis, so that the working efficiency is further improved and the number of parts is reduced.
