  As shown in FIG. 1, wiring ducts 7 for storing wirings connected to internal devices are arranged on the ceiling plate 6 of each electric device storage box 1. Although the structure will be described later, the wiring ducts 7 of the electric device storage boxes 1 are connected to each other to form a wiring path, and wiring (not shown) can be provided inside thereof. In addition, although the electrical equipment storage box group is formed in two rows, there is no problem even if it is formed in one row.

  Reference numeral 8 denotes a ladder spanned between the wiring ducts 7 and 7 of the row of electrical equipment storage boxes. The ladder 8 is used to bridge power lines and communication lines between the columns. In FIG. 1, one end is fixed on the rear wiring duct 7 by a fixing portion 9 and the other end is shown in FIG. Is flexibly supported on the front wiring duct 7 by the band portion 10. The reason for adopting such a structure is to cope with a change in the interval between rows when the electrical equipment storage box group swings differently for each row due to an external force such as an earthquake. However, this ladder 8 is outside the scope of the present invention, and the ceiling wiring structure of the present invention will be described in detail below.

  As shown in FIG. 2, the ceiling plate 6 of the electrical equipment storage box 1 is formed with a plurality of wiring holes 11 for passing wiring connected to the internal equipment. In this example, three wiring holes 11 are formed in the depth direction of the electric device storage box 1. These wiring holes 11 are for passing a power line and a communication line, and their arrangements are various as will be described later. The unused wiring holes 11 can be covered with a blank panel.

As shown in FIG. 3, the wiring duct 7 forms an outer shell with a pair of front and rear side plates 12 extending in the left-right direction and left and right connecting rails 13 connecting the side plates 12, 12. Fixed rails 14 are attached to the inside of the side plates 12, and the wiring holding rails 15 are held by these fixed rails 14. The wiring holding rail 15 is provided with a large number of insertion holes 16 through which the wiring binding tool is passed. The fixed rail 14 has a substantially U-shaped cross section, and is fixed to the side plate 12 by screws, welding or the like. The fixed rail 14 is formed with a plurality of holding holes 14 a of the wiring holding rail 15, and the position can be changed according to the shape of the wiring hole 11 of the ceiling board 6. The holding hole 14 a is not formed at a position corresponding to the wiring hole 11 of the ceiling plate 6, and the wiring holding rail 15 is formed so as to be disposed outside the left and right width of the wiring hole 11. The wiring can be taken in and out through the hole 11. In addition, an attachment portion 17 to the ceiling plate 6 of the electrical equipment storage box 1 is provided at the lower end portion of the wiring duct 7. Specifically, the connecting rail 13 may be provided with a locking piece for attachment to the ceiling plate 6 or a screw hole.

  The wiring duct 7 is disposed so as to straddle a plurality of wiring holes 11 formed in the ceiling plate 6 of the electrical equipment storage box 1. That is, the fixed rail 14 and the wiring holding rail 15 are disposed outside the left and right widths of the wiring hole 11, so that the wiring can be taken in and out through the wiring hole 11. Further, the wiring duct 7 is arranged so that its mounting position can be selected in the depth direction of the ceiling board 6. For this purpose, for example, as shown in FIG. 2, a plurality of mounting holes 18 such as screw holes are formed in the ceiling plate 6 so that the mounting position in the depth direction is variable.

  The side plate 12 has a role of a blank panel that hides the wiring so that the wiring cannot be seen, and a role that holds the wiring so that the wiring does not collapse. As shown in FIG. 3, wiring holes 19 and 19 are formed in the lower center portion and the left and right end portions of the side plate 12. These are used to enter or exit from the outside of the wiring duct 7. The wiring hole 19 in the central portion is set to have the same width as the width in the left-right direction of the wiring hole 11 formed in the ceiling plate 6 or a wide width. As a result, when the wiring is drawn from the wiring hole 11, the wiring is prevented from coming into contact with the end portion of the wiring hole 19 to break the coating.

Next, the relationship between the layout of the wiring holes 11 and the internal devices will be described.
When the internal device is a server, communication lines and the like connected to the server are formed in the direction of the front door 3, and power from the outside is often output from the rear door 5 side. Therefore, as shown in FIGS. 5 and 6, the wiring hole 11 on the backmost side is generally formed with a wiring hole 11a for a power supply line and a wiring hole 11b for a communication line on the front door side. Further, since the communication line has a larger wiring amount than the power supply line, the communication line wiring hole 11b is formed larger.

  In addition, as shown in FIGS. 5 and 6, a wiring hole 11 c for communication lines may be formed at the center of the ceiling plate 6. For example, there may be a case where a patch panel for connector connection is arranged in front of the electrical equipment storage box 1. The data center operator connects the communication line to the back side of the patch panel, and the user pulls out the communication line connected to the connector from the front side of the patch panel and connects it to a device such as a hub inside the electrical equipment storage box 1. It is possible to use a communication line of a person. Such a connector may be drawn not only from the same electrical equipment storage box 1 but also from another electrical equipment storage box 1, and in such a case, from the central wiring hole 11c for communication lines. The wiring that is pulled in and connected to the front is not necessarily the same electrical equipment storage box 1, and therefore, the wiring is led out from the wiring hole 11 b for the front communication line.

  Thus, the layout of the wiring hole 11 and the wiring capacity passing through the wiring hole 11 are various. However, since the position of the wiring duct 7 of the present invention can be changed in the depth direction of the electrical equipment storage box 1, a flexible response is possible. This will be specifically described below.

It straddles about 3 positions. By adopting such a configuration, both the power line and the communication line can be drawn into and held in one wiring duct 7. As described above, since the wiring hole 19 having the same or wider width as the width in the left-right direction of the wiring hole 11 is formed in the lower part of the side plate 12, not only from the lower side of the wiring duct 7, but also from the side surface. The wiring can be drawn into the wiring duct 7 also from the lower side.

  When both the power supply line and the communication line are held in the same wiring duct 7 as described above, a partition plate 20 can be arranged as shown in FIGS. 7 and 8 to separate both wirings. preferable. The attachment position of the partition plate 20 is also made variable in the depth direction, and is divided according to the amount of wiring. It is most preferable that the area ratio of the wiring hole 11 covered with the wiring duct 7 and the area ratio in the wiring duct 7 by the partition plate 20 are substantially the same.

  In the second embodiment shown in FIG. 9 and FIG. 10, the communication line connected to the internal device of the electrical device storage box 1 is input / output from the wiring hole 11 of the ceiling plate 6. This is a case where the section is connected to / out of the electrical equipment storage box 1 from the floor side. In such a case, since the opening area of the power supply line wiring hole 11a can be reduced, the wiring duct 7 extends over only a part of the power supply line wiring hole 11a, and the central communication line wiring It arrange | positions so that all the holes 11c may be covered.

  In the third embodiment shown in FIG. 11 and FIG. 12, the communication lines connected to the internal devices of the electrical device storage box 1 are input / output through the wiring holes 11 of the ceiling plate 6, but all of the power supply lines are connected. Is the case where the incoming / outgoing line is made from the floor side of the electrical equipment storage box 1. In such a case, the wiring hole 11a for the power supply line is not necessary, so the wiring duct 7 extends over only a part of the central wiring hole 11c for the communication line, and the wiring hole for the communication line on the front door side. 11b is arranged so as to cover all.

  In the fourth embodiment shown in FIGS. 13 and 14, as in the third embodiment, all communication lines are input / output through the wiring holes 11 of the ceiling plate 6, but all the power lines are used for electrical equipment storage. This is the case where incoming / outgoing from the floor side of the box 1, and due to the arrangement position of the units formed inside the electrical equipment storage box 1, the central communication wire wiring hole 11 c and the front door side The case where it is necessary to enter / exit the communication line from the wiring hole 11b for the communication line is shown. In this embodiment, the wiring duct 7 provided with the partition plate 20 is installed so as to straddle these two wiring holes 11c and the wiring holes 11b.

  FIG. 15 shows a fifth embodiment, and shows an example in which the wiring duct 7 is installed so as to straddle the three wiring holes 11a, 11b, and 11c. Thus, even if the area opened inside the wiring duct 7 of the wiring holes 11a and 11b is small, there is no problem when the wiring of the sensor for measuring the internal temperature of the electrical equipment storage box 1 is passed.

  FIG. 16 shows the sixth embodiment, and shows an example in which the wiring duct 7 is installed so as to straddle only the single wiring hole 11b. The installation position of the wiring duct 7 can be freely changed according to the required wiring capacity.

  As described above, since the wiring duct 7 is formed so as to straddle the plurality of wiring holes 11, the position of the wiring duct 7 depends on the wiring capacity and the wiring location of the entire electrical equipment storage box 1. As a matter of course, it is possible to respond flexibly even in accordance with the wiring capacity of one wiring hole. In addition, since a plurality of wiring holes 11 for passing wirings connected to the internal device are formed in the ceiling plate 6 in the depth direction, wiring work can be easily performed.
