Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an electronic device housing device in which the rigidity of a rack in which electronic devices are housed is increased to improve earthquake resistance.

(Prior art) Fig. 4 is a configuration diagram of a conventional rack, in which (a) is a cross-sectional view;
(b) is a side view. In the figure, 1 is a ceiling plate, 2 is a bottom plate, 3 is a column attached to the four corners of the ceiling plate 1 and bottom plate 2, and 4 is a chassis installed between the columns 3.
5 is a chassis that houses a printed circuit board, etc., and 6 is a side plate that reinforces the bracket 3.

In the device configured in this way, the chassis 5 is fixed to the mounting column 4. Pillar 3 is ceiling plate 1, bottom plate 2 and @ slope 6
Since it is surrounded by , it is a thin structure and restrains the deformation of the column 3.

(Problem to be solved by the invention) However, the dimensions of the rack are, for example, 0.6xO, 8x
2.1 (m) weighs 100! The dimensions of the chassis are, for example, 0.5 x O, 3 x O, 2 (m) and the weight is ff115ks, so the weight of a rack on which a plurality of chassis are mounted becomes large. Therefore, when pillar 3 bears the load, the response to vibration becomes poor, and pillar 3 becomes ITII.
There was a problem in that it swayed or twisted backwards.

The present invention solves these problems, and aims to increase the rigidity of the entire rack to prevent shaking and twisting of the entire rack, thereby improving the reliability of the equipment.

(Means for Solving the Problems) The present invention achieves the above object in an electronic equipment housing device in which a chassis is mounted on mounting pillars arranged on two opposing sides of pillars provided at four corners. The surface of the mounting column on which the chassis is attached is made substantially perpendicular to the side, and a reinforcing plate having a crank-shaped cross-section is provided that comes into contact with this surface, and the column and the mounting column are fixed by this reinforcing plate. It is something.

(effect) The column and the mounting column are fixed together by a reinforcing plate.

Since the reinforcing plate has a crank-shaped cross section, it does not interfere with chassis installation.

(Example) The present invention will be explained below using the drawings.

FIG. 1 is a configuration diagram showing an embodiment of the present invention, in which (a) is a cross-sectional view and (b) is a side view. In FIG. 1, parts having the same functions as those in FIG. 4 are given the same reference numerals, and their explanations will be omitted. In the figure, 7 is a reinforcing plate fixed to the pillar 3 and the mounting pillar 4, and the width W is sufficiently small compared to the height of the rack.

FIG. 2 is an explanatory diagram of the state in which the reinforcing plate 7 is attached to the rack. In the figure, reference numeral 41 denotes a through hole formed in the mounting column 4, which is used for warming the chassis. The through hole 41 is approximately perpendicular to the side of the pillar 3, and!
The distance between 13 and the mounting post 4 is a, and the distance between the mounting posts 4 is b. Although the distance between the pillar 3 and the mounting pillar 4 is equal to a in this example, they may be different. Reference numeral 71 denotes a crank part provided in the middle of the reinforcing plate 7, and the crank arm contacts the surface having the through hole 41, and the interval between the crank parts 71 is b.

In the apparatus configured in this manner, the reinforcing plate 7 restrains the deformation of 1-J3 and the mounting post 4, so the rigidity of the entire rack is increased and the shaking and twisting of the mounting post 4 is reduced.

Furthermore, if the shape of the reinforcing plate 7 is maintained accurately, it can also be used as a positioning jig during rack assembly.

FIG. 3 is a sectional view showing a modified embodiment of the present invention.

In the figure, 72 is a reinforcing plate that connects the pillars 3 and mounting posts 4, and 73 is a reinforcing plate that connects the mounting posts 4 to each other. By dividing the reinforcing plate 7 in this way, the pillars 3. It may be fixed to the mounting column 4 by welding.

It goes without saying that the same effect can be achieved even if a plurality of reinforcing plates 7 are attached in a band shape.

(Effects of the Invention) As explained above, according to the present invention, since the reinforcing plate 7 having a crank is used to fix the rack 3 and the mounting tlf 4, the rack has high rigidity and excellent vibration resistance. The device can be realized.
