  Hereinafter, embodiments embodying the present invention will be described in detail with reference to the drawings. 1 to 4 are explanatory views of rack rows showing an example of a rack row power feeding system according to the present invention, FIG. 1 is a perspective view, FIG. 2 is a front view, FIG. 3 is a plan view, and FIG. is there. In each figure, 1 is a rack for storing electronic devices such as servers, 2 is a bus duct, 4 is a hanging member (hanging means) for suspending and supporting the bus duct 2, 5 is a lead-in line into the rack 1 A branching box used when connecting (not shown) to the bus duct 2 is a wire which is stretched between the suspending member 4 and the bus duct 2. Here, a state is shown in which the rack row is formed by arranging four racks 1 in a row.

The rack 1 has doors (a front door 1a and a rear door 1b) on the front and the rear, respectively, and is configured to be able to be opened and closed from the front and rear. Further, the rack 1 is configured to be able to be closed individually by providing a top plate 1c and left and right side plates 1d. And in the top plate 1c, the inlet 11 for drawing in a power supply from the bus duct 2 is opened.
A communication line or the like connected to the electronic device stored in the rack 1 is introduced from an opening (not shown) provided at the bottom of the rack 1.

The bus duct 2 is configured by accommodating a plurality of conductor bars 3 as power supply lines in a duct 2a formed of a metal rectangular cylinder, and has a length matched to the width of the entire rack row. In FIG. 1, it has a length four times the width of the rack 1 and has a length equal to the width obtained by arranging four racks 1 in a row. The conductor bars 3 are made of strip-shaped metal plates, and the plurality of conductor bars 3 are accommodated in the duct 2 a so that the width direction is vertically oriented and the front and rear directions overlap.
The respective portions of the conductor bars 3 are appropriately supported by the insulating members, and the length of the duct 2a at the time of manufacture is arbitrary, and may be connected as long as it is shorter than the entire width of the racks 1 arranged in a row. .

FIG. 5 shows an enlarged view of part A, and as shown in FIG. 5, an opening 22 for connecting a lead-in wire introduced into the rack 1 is provided on the upper surface of the bus duct 2. However, the opening 22 is closed by the closing member 23 so as to prevent dust and the like from entering. In the closing member 23, the closing member 23 is opened by the pressing of the terminal portion (not shown) of the branch box 5 by the connection operation of the branch box 5 to the conductor bar 3, and the closing member 23 and the conductor bar 3 in the duct 2a are opened. Connection is possible.
One end of the bus duct 2 is used to connect a power supply line disposed from a ceiling or the like, and the other end not used is covered with an end cap or the like.

As shown in FIG. 5, the hanging member 4 includes a support 4a whose upper portion is bent in a U-shape and directed downward, and a hook 4b attached to the end of the support 4a. The base of is fixed to the top plate 1 c of the rack 1.
Specifically, a reinforcing member (not shown) is disposed in the rack 1 which is the back surface of the top plate 1c of the rack 1, and the base end of the column 4a is fixed by bolts or the like via the reinforcing member. 4a is placed upright. In this manner, a total of four suspension members 4 are attached to the left and right of the rack row, and the suspension members 4 disposed at the front and rear positions of the top plate 1c face each other.

A connecting member 7 for attaching the wire 6 is attached to the hanging position of the bus duct 2 corresponding to the suspending member 4. The connecting member 7 is composed of two gripping pieces 7a and 7b for gripping the duct 2a from above and below as shown in FIG. 5, and holes 7c for inserting and connecting the wire 6 to both ends of the upper gripping piece 7a. Is drilled.
The wire 6 is stretched between the hole 7c and the hook 4b of the hanging member 4, and the bus duct 2 is placed in the air. In addition, the same member is used for two holding pieces 7a and 7b here.

  The branch box 5 has a branch breaker (not shown) incorporated therein, has a connection portion 5a (shown in FIG. 4) for connecting to the conductor bar 3 of the bus duct 2 at the lower portion, and is drawn in at the side It has a terminal 5b for connecting a wire. The connecting portion 5 a protruding downward is connected to the conductor bar 3 and the lead-in wire connected to the terminal 5 b is connected to the conductor bar 3 by the mounting operation of the branch box 5 to the bus duct 2.

As described above, since the bus duct 2 is suspended and supported on the rack 1, the rack 1 can be easily moved, and expansion, replacement, and the like can be easily performed. Further, the installation of the bus duct 2 can be suspended, and the installation work of the bus duct 2 can be simplified.
Further, since the bus duct 2 is suspended and supported at two places on the left and right and disposed above the rack row, the bus duct 2 can be stably supported, and the bus duct 2 is suspended and supported by the wire 6 from the front and rear direction of the rack 1 Therefore, it can be supported in a stable state.
In addition, although the bus duct 2 is suspended by the wire 6, it is not limited to this, and as long as it is a strong string-like member, other members can be used.

6 and 7 show other examples of the rack row power feeding system, FIG. 6 is a perspective view of the rack row, and FIG. 7 is an enlarged view of a portion B. The structure which suspends the bus duct 2 differs from the said embodiment, and a difference is demonstrated below. In addition, the same code | symbol is provided to the component in common with the said form, and description is abbreviate | omitted.
On the top plate 1c of the rack 1 arranged at the left and right ends of the rack row, it comprises a standing portion 14a standing upright from the top plate 1c and a horizontal bridging portion 14b stretched between the standing portions 14a. A U-shaped gate-like member (hanging means) 14 is provided, and the bus duct 2 is suspended from the gate member 14.

Specifically, the gate-shaped member 14 formed in a U-shape consisting of the standing portion 14a and the bridging portion 14b is formed by welding a metal rod, and the top plate 1c is formed in the same manner as the column portion 4a of the above embodiment. It is fixed by bolts or the like, and erected so as to face from the left and right in the rack row direction on the rack row. A vertical hole is bored in the horizontal bridging portion of the gate-like member 14 in accordance with the width of the bus duct 2, and a bolt 16 which is a bar is inserted and suspended.
A connecting member 7 consisting of two gripping pieces 7a and 7b sandwiching the bus duct 2 in the same manner as the above embodiment is connected to the lower end of the bolt 16 thus suspended and suspended from the gate-like member 14 to arrange the bus duct 2 It is done.

  As described above, since the bus duct 2 is suspended and supported from the gate-like member 14, it can be stably supported in a stable manner.

In the above embodiment, the front and rear two places (two on the left and right in the row of racks) of the bus duct 2 are supported by the suspending means 4, but in addition to the two places on the left and right of the bus duct 2, the suspended position Other sites may be added and supported.
Although the part to which the branch box 5 is attached is the upper surface of the bus duct 2, the opening 11 may be formed on the lower surface of the duct 2a and attached to the lower surface.
Furthermore, although the space is provided between the gate-like member 14 and the bus duct in the configuration in which the gate-like member 14 is suspended, the gate-like member 14 and the bus duct 2 may be closely attached.
