Each equipment rack 1 has a frame-shaped rack in which units 2, for example, printed boards 3 mounted vertically in parallel, are stacked vertically, and the upper part of each equipment rack is a rack (not shown). They are connected and fixed using a connecting stand to prevent them from slipping.

A front door 4 is attached to the front of each equipment rack, and a rear door is attached to the rear. Then, frame closing covers 11 are removably attached to the front and rear surfaces of the adjacent space 10 to close the adjacent space 10.

A cable duct 6 continuous in the left-right direction is provided at the upper part of the equipment rack 1. cable duct 6
consists of front and rear duct plates 7, 8 provided parallel to the front and rear ends of the upper part of the equipment rack 1, and a duct top cover 9 covering these. These duct plates 7 and 8 are continuous with no gaps. A large number of cables 5 are laid within this cable duct 6, and a required number of cables 5 are suspended within the space 10 between predetermined equipment racks. A connector 5A is connected to the tip of the hanging cable 5, passed through a groove-shaped cable receiver at the bottom of the unit 2 from the side, and connected to a predetermined printed circuit board 3.

To perform the above work, first remove the gap cover 11 and the duct top cover 9, and then insert the specified cable 5 from the top of the cable duct 6 into the adjacent gap 10 of the equipment rack 1 with the connector 5A at the beginning. Let it droop. Next, the cable connector 5A is connected to the printed board 3 as described above, and the gap closing covers 11 are attached to the front and rear of the adjacent gap 10 to close it, and the top surface of the cable duct 6 is covered with the duct top cover 9.

[Problem that the invention seeks to solve]

According to the above conventional equipment rack, the cable duct 6
is formed continuously in the left and right direction, a predetermined cable 5 is selected from the many cables 5 in the cable duct 6, and a cable 5 is connected from the top of the cable duct 6 with the connector 5A at the beginning in a narrow adjacent space 10. You have to insert it by pushing it in, so
This insertion work is difficult and time consuming, and because the connector 5A is relatively large, there is a risk that the cable 5 or the connector 5A itself may be damaged.

In order to eliminate the above-mentioned problem, if the distance between the adjacent devices is widened, another problem arises, such as an increase in the installation floor area of the device.

The front and rear duct plates 7 and 8, which are longer than the front width of the equipment rack 1 and difficult to obtain dimensional accuracy, must be processed with high dimensional accuracy.In addition to problems such as creating gaps and poor appearance, the cable 5 Adjacent distance depending on amount = 10
This problem is even more serious in areas where it is necessary to widen the area.

[Means for solving problems]

According to the cable wiring structure of the equipment rack, the cable wiring structure of the equipment rack is characterized in that when wiring the equipment hanging down between the equipment racks, the closing cover between the racks and the closing cover between the ducts are removed, and the space between the two is used as a space for inserting the cable. It will be resolved.

[Effect]

According to the present invention, by removing the cover, between the frame, between the blocking cover and the duct, and between the vertically adjacent spaces including the cable ducts on the front and rear surfaces,
Since the cables are formed, the cables can be successively fitted into the adjacent spaces from the front or rear surface of the rack. Therefore, the wiring work becomes easy and the work time can be shortened.

In addition, since cables can be freely introduced between equipment racks from the front of the equipment rack, cables and connectors will not be rubbed, so there is no risk of damage. It becomes possible to reduce the installation floor space.

It is sufficient to standardize the cable ducts on the equipment racks and prepare a bridge closing cover and a duct closing cover with widths that correspond to the spacing between adjacent units, allowing for flexibility in design.
