As shown by an arrow C, the electronic device passes through the entire surface of the electronic device, or as shown by an arrow D, passes between the bottom plate 3 and the top plate 2 of the stacked electronic devices, and is ejected to the rear of the electronic device.

Next, a method of attaching an exterior plate of a conventional electronic device will be described with reference to FIGS. FIG. 16 is a perspective view showing a case where a conventional electronic device is stacked in two stages and an exterior plate is attached, and FIG. 17 is a perspective view for explaining a method of attaching the exterior plate. In FIG. 16, reference numeral 51 denotes a rear exterior plate fixed to the rear surface of the electronic device;
Reference numeral 2 denotes a front exterior plate that protects the front portion of the electronic device, and 53 denotes a top exterior plate that protects the top surface of the electronic device. As shown in FIG. 17, a ventilation hole 52a is provided on the lower surface of the front exterior plate 52, and a ventilation hole 51a is provided on the upper surface of the rear exterior plate 51 as shown in FIG.

Note that the top exterior plate 53 is not usually provided with a ventilation hole because dust and the like can easily enter therein.

With this structure, air is taken in from the ventilation holes 52a provided in the front exterior plate 52, and the heated air is released from the ventilation holes 51a provided in the rear exterior plate 51 while cooling the inside. Can be.

Reference numeral 51b denotes a screw hole provided around the end face of the rear exterior plate 51, 51c denotes an opening provided as an outlet of the cable 13, 52b denotes a screw hole provided around the end face of the front exterior plate, and 53a denotes a top.

[0016]

However, in the above configuration, as shown in FIG. 15, as the number of electronic devices to be stacked increases, the cable 13 becomes a thick bundle, and even if the cable 13 is output backward, the cable 13 becomes a bundle. There is a problem that it is necessary to use an unnecessarily large electronic device because it requires a sufficient space. In addition, since the cables 13 are densely arranged, the cable 13 may hinder the removal of the printed circuit board 9,
Since the internal state is difficult to understand, there is also a problem that it takes time to replace the printed circuit board 9. In addition, there is a problem that a space for the bundled cables 13 is required even when the cable is taken out to the rear, and that the electronic device needs to be turned over or a worker needs to be moved for cable processing.

Also, a jig for holding the left and right side plates 1 is required for assembling, and two wrench 12 or pliers for supporting the head of the hexagon bolt 10 are required for stacking or disassembling. In addition, there is a problem that workability is poor, and it is fixed with the bolt 10 and the nut 11, but the surface of the reinforcing bent portion 1c is not microscopically flat.
The electric contact strength is weak, and there is also a problem that it is difficult to transmit harmful static electricity generated on the printed circuit board 9 by hand contact to a lower electronic device. Further, since metal components of the electronic device are plated for rust prevention, it is difficult to conduct static electricity, and there is a problem that the electronic component stays in the device and adversely affects the printed circuit board 9.

If the device is not a mere experimental device but a product, it is necessary to protect the electronic device itself with an exterior plate for the purpose of protecting the interior in consideration of the design.

In this case, when the printed circuit board is housed in the apparatus, it is preferable that only the front part of the apparatus can be attached and detached. It is common for both sides of the device to pass the power supply line on one side and the control line on the other side (separate to prevent noise on the control line), so that the left and right outer panels can be easily If it is removed, it is conceivable that an ordinary person may accidentally remove or cut the line itself, which has a great effect on the device itself.

In terms of the heat radiation effect, it is needless to say that the larger the area of the opening (air hole) is, the larger the effect is from the cooling surface. It goes without saying that the contact with the electric component causes a short circuit at the portion or the device itself, and particularly in the case of the front portion, it is easy to touch the component on the printed circuit board in the device. Therefore, an unnecessary opening cannot be provided.

As the number of stacks of the apparatus itself increases, the number of cables housed in the apparatus may increase, and in some cases, the side outer plate may not be closed.

The present invention solves the above problems,
An object of the present invention is to provide an electronic device which is easy to assemble, does not discharge static electricity to the outside of the device and does not destroy electric components on a printed circuit board, has excellent heat dissipation properties, and can cope with an increase in the number of cables to be processed. .
