[0007]

2. Description of the Related Art FIG. 6 is a partially cutaway perspective view showing a conventional cable support structure. In FIG. 6, a plurality of pedestals 2 each having a U-shaped cross section support and reinforce the bottom of the equipment rack body 1.
The electronic device is configured to be attached to the bottom of the device rack body 1, and the pedestal 2 is placed on the floor.

3 accommodates a cable bundle 6 to be wired;
It is a cable duct whose length is approximately equal to the left and right length of the equipment rack main body 1 and whose cross section is approximately U-shaped. The cable duct 3 consists of a bottom plate placed on the pedestal, a side plate 33 in contact with the front or rear surface of the equipment rack body 1, and the other side plate 34 opposite to the side plate 33, and the upper part of the side plate 34 is bent inward at a right angle. This serves as a cover seating portion 35.

Furthermore, a pair of slits 31 are bored in the bottom plate of the cable duct 3 so as to face each other in the front and rear. One of the pair of slits 31 is provided near the side plate 33, and the other is provided at a position closer to the apparatus rack main body 1 than the inner side edge of the cover seating portion 35.

The slits 31 are provided in desired pairs at equal pitches in the left and right direction of the cable duct 3. The above-mentioned cable duct 3 is bridged to the pedestal 2 to form the equipment frame body 1.
It is attached to the front and rear of the

5 is the height of the side plate 33 of the cable duct 3.
The cable support is made of a rectangular metal plate that is sufficiently larger than the height of the side plate 34, and its lower part is bent at a right angle and engaged with the bottom plate of the cable duct.

That is, the lower part of the cable support 5 is inserted into the slit 31, the upper surface of the bent portion is brought into close contact with the lower surface of the bottom plate, and the cable support 5 is installed in the cable duct 3, and then the bent portion and the bottom plate are bolted together. It is fixed using 32.

A large number of cables are accommodated and routed between the cable supports 5, and the bottom plate of the cable duct 3 supports the lower surface of the cable bundle 6, and the cable supports 5 support and align the sides of the cable bundle 6. are doing.

[0014] At this time, the tip of a bolt 32 for fixing the cable support 5 protrudes from the bottom plate of the cable duct 3. Therefore, the tip of the bolt 32 hits the cable 6 during wiring, causing damage to the cable 6.

In order to prevent this, a protective sheet 7 is laid on the bottom plate of the cable duct 3. To be more specific, the protective sheet 7 is a belt-shaped synthetic resin sheet whose length is approximately equal to the length of the cable duct 3.

[Problems to be Solved by the Invention] In the conventional cable support structure, the outer side plate of the cable duct is bent inward in a U-shape to provide a cover seating portion at the top, and the cable support is placed inside the cover seating portion. It is being planted. Therefore, the lower part of this cover seating part (A shown in FIG. 6)
section) cannot accommodate cables because it is separated by a cable support.

Furthermore, if the height of the cable support is increased in order to increase the accommodating cross-sectional area of the cable bundle, cable wiring work becomes difficult due to the height of the cable support.

[0019] Therefore, conventional measures have been taken to accommodate the desired number of cables by increasing the width of the bottom plate of the cable duct. That is, the conventional structure has a problem in that it hinders miniaturization of electronic devices.

On the other hand, conventionally, the protective sheet is bent into a U shape and laid inside the cable support 5. Therefore, there is a problem that the side portions of the protective sheet tend to fall inward, making it difficult to perform cable wiring work.

The present invention was created in view of the above points, and an object of the present invention is to provide a cable support structure for an electronic device that facilitates cable wiring work and reduces the width of the electronic device. There is.

The cable duct 10 is attached to the bottom plate 13 of the cable duct 10 in close proximity to the outside thereof.

Therefore, cables can also be accommodated in the space below the stepped portion 22A of the cable support 22. Further, the cable support 23 shown in FIG. 2 is planted straight, and the duct side plate 40A is arranged so that the cover seating part 41A is located above the cable support 23 and the vertical plate part is close to the outside of the cable support 23. It is attached to the bottom plate 13 of the cable duct 10.

Therefore, the bottom plate 1 of the cable duct 10
Cables can be accommodated in almost all of the space above 3. That is, since the space above the cable duct is effectively used in both cases, there is no need to particularly widen the width of the bottom plate of the cable duct.

In addition, when storing and wiring cables in a cable duct, as shown in FIG. 1 (A) or FIG. After finishing, the protective sheet 70 is raised up to wrap the cable bundle, and then the duct side plate is attached to the cable duct.
