DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box for storing electrical equipment made of metal used as an outer box of a distribution board, a distribution board, or the like.

[0002]

2. Description of the Related Art A relatively small box for storing electric equipment used as an outer box of a distribution board, a distribution board, or the like is manufactured by bending a metal plate from three sides and welding a joint. In general, a relatively large one is manufactured by a method of screwing a metal plate to a frame. However, such a conventional box for storing electric equipment requires many steps for manufacturing, and also requires many parts and steps for attaching a separately manufactured door with a hinge.

[0003] Further, it is necessary to incorporate many parts such as a shield plate, a shield lock, a base for mounting electric equipment, a rail for mounting electric equipment, and a drawing inside the box for storing electric equipment. Each component must be attached to the back surface of the door or the inside of the box body by welding or the like, and many steps are required for that.

[0004]

SUMMARY OF THE INVENTION It is a main object of the present invention to solve the above-mentioned conventional problems and to provide a box for storing electric equipment in which a door and a box body can be easily manufactured. Is what you do. It is another object of the present invention to provide a box for storing electric equipment, in which each component can be easily mounted inside a door or a box body.

[0005]

Means for Solving the Problems] Electrical device-accommodating box of the present invention has been made to solve the aforementioned problem, extrusion also
Is the back plate made of metal material integrally formed by drawing.
A metal box in a box with a U-shaped cross section with side plates standing on both sides
For storing electrical equipment with doors made of wood that can be freely opened and closed
Box, with one side of the door and the end of the side plate
Molded at the same time as integral molding by extrusion or drawing
It is characterized in that each hinge portion is provided . In addition, on the side plate and the back plate of the door or the box body,
By integrally forming the mounting portions of the top plate and the bottom plate, assembly can be performed more easily. Further, by integrally forming the holding portions and the like of the above-mentioned many parts, these parts can be easily attached. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0006]

FIG. 1 is a perspective view showing a box body 1 of a box for storing electric equipment according to the present invention, wherein a side plate 2 and a back plate 3 of the box body 1 are optionally formed of extruded or drawn metal material. It is integrally molded to the length. The material of the metal is not particularly limited, but aluminum or an aluminum alloy having excellent workability is suitable. The Figure 2 is a perspective view showing the door 4 of the electrical device-accommodating box, the door 4 of this are also integrally formed by a metal timber of extrusion or drawing.

As shown in FIG. 1, a hinge 5 on the side of the box body having a cross-sectional shape in which a part of a circle is cut off is integrally formed at an end of one side plate 2 of the box body 1. Further, as shown in FIG. 2, a hinge part 6 on the door side having a sectional shape in which a part of a double circle is cut off is integrally formed on one back surface of the door 4. Thus, the box body 1 and the door 4 thus integrally formed are engaged with each other as shown in FIG. 3 while sliding the hinge portions 5 and 6 in the longitudinal direction (forming direction).
The door 4 can be attached to the door so that it can be opened and closed freely.

A hook 7 having an L-shaped cross section is integrally formed on the other back surface of the door 4. And box body 1
A door locking portion 8 having an L-shaped cross-sectional shape whose tip projects toward the front side of the box body 1 is integrally formed at the end of the other side plate 2. Therefore, when the door 4 is closed, the hook 7 of the door 4 elastically engages with the door locking portion 8 of the box body 1 from the outside, and the door 4 can be locked so as not to open. .
In this embodiment, both the box body 1 and the door 4 are integrally formed by extruded or drawn metal material, but only one of them may be formed by extruded or drawn.

As described above, it is necessary to attach a top plate and a bottom plate to the box body 1 and the door 4 which are integrally formed of the extruded or drawn metal material. Therefore, as shown in FIGS. 1 and 2, the box body 1 and the door 4 are integrally formed with mounting portions 9 and 10 for a top plate and a bottom plate. Each of them has a shape capable of receiving the tip of a tapping screw or the like, and the top plate and the bottom plate can be easily attached as shown in the figure. The hinge 6 provided on the door 4 as shown in FIG.
Similarly to the case of the bottom plate 0, a shape such that a tip of a tapping screw or the like can be received may be provided, and the same function as that of the mounting portion 10 of the bottom plate may be provided.

Further, as shown in FIG. 2, in this embodiment, a holding portion 11 shown in the drawing is integrally formed on the back surface of the door 4. This portion has a U-shaped groove-shaped cross-section formed opposite to each other, and a drawing case 12 having a lower end bent into an L-shape is inserted between them so that the drawing can be easily put on the back surface of the door 4. 12 can be attached. Heretofore, since the drawing holder was attached to the back surface of the door 4 by welding or stud bolts, there was a problem that skill was required and welding marks and the like were likely to appear on the surface of the door 4. Not only is it easy, but also there is an advantage that the accuracy of the mounting position can be easily obtained.

As shown in FIG. 1, the side plate 2 of the box body 1 has a support 13 for a shield plate and a holding portion 14 for a shield lock.
And are integrally formed. And as shown in FIG.
One end of the shield plate 15 can be fixed to these portions. The other end of the shield plate 15 is attached to a hinge mounting portion of the shield plate formed integrally with the side plate 2. Conventionally, a leg member for a shield plate is attached to a base inside the box body 1 and the shield plate 15 is fixed by using these. According to the present invention, the shield plate is attached to the side plate 2 of the box body 1. Since the fixing member 15 can be fixed, a component serving as a leg portion of the shield plate is not required, and it is possible to increase a space for accommodating a device or the like.

Next, in another embodiment shown in FIG. 5, a bolt holder 17 of a base mounting bolt 16 is integrally formed on the back plate 3 of the box body 1. The bolt holder 17 has a groove-like shape in which the bolt head 18 of the base mounting bolt 16 can be slidably fitted. By sliding the base mounting bolt 16, the base 19 can be arbitrarily positioned. Can be fixed. Therefore, unlike the conventional method in which the bolt holder is fixed by welding, there is an advantage that the size of the base 19 and a change in the mounting position can be easily coped with. Also, the number of parts can be reduced as compared with the conventional case.

Further, in another embodiment shown in FIG. 6, a ridge 20 similar to a rail for mounting electric equipment such as an IEC rail is integrally formed on the back plate 3 of the box body 1.
The IEC rail is a standardized rail for mounting an electric device, and was conventionally screwed to a base.
However, according to the present invention, the IEC is directly
Since the protrusions 20 similar to the rails can be provided, the depth of the box main body 1 can be reduced by the amount of the base, and the thickness of the box main body 1 can be reduced.

[0014]

As described above, the box for storing electric equipment according to the present invention is formed by integrally molding the door and the box body with the extruded or drawn metal material. Yes, and the door is easy to install. Further, the box for storing electric equipment of the present invention can easily mount many parts such as a shield plate, a shield lock, a base for mounting electric equipment, a rail for mounting electric equipment, a drawing, and the like. It has advantages and its practical value is extremely large.
