Embodiments of the present invention will be described below. The cabinet of this embodiment is for housing equipment such as a server.
FIG. 1 is a perspective view for explaining the structure of a DC power supply cabinet according to the present invention, wherein 1 is a vertical frame, 2 is a horizontal frame, and 3 is a depth frame. The skeleton structure of the cabinet is formed by these 12 frames. Reference numeral 4 denotes a mounting rail arranged in parallel in the vicinity of the inner side of each vertical frame 1, and includes a large number of device mounting holes 4a so that devices such as servers can be mounted at various heights. The vertical frame 1 and the mount rail 4 constitute a vertical column member inside the cabinet. Although there are a total of four mount rails 4, the device is usually supported by the left and right two on the front side, and in the case of a large device, it is supported by four.

  As shown in FIG. 2, a partition plate 5 is attached to the column member to partition the central space 6 and the side space 7 in the vicinity of the cabinet opening. In the present embodiment, the partition plate 5 is a flat plate bent in a substantially L shape, and is attached between the mount rail 4 and the vertical frame 1 by a plurality of mounting brackets. The partition plate 5 is attached to the outside of the device mounting hole 4a of the mount rail 4 so as not to obstruct the device mounting.

  In order to supply DC power to devices such as servers, a DC power bar is arranged vertically on the back side of the cabinet. The DC power source bar is composed of a positive electrode bar 8 and a negative electrode bar 9, and is arranged vertically in the side space 7 defined by the partition plate 5. The reason why the DC power supply bar is arranged on the back side of the cabinet is that it is easy to supply DC power to the power plug connected to the back of the server or the like. In the present invention, since the DC power supply bar is disposed in the side space 7 partitioned by the partition plate 5, the storage space of the device is not compressed. Further, the access to the charging unit can be restricted by the partition plate 5.

  In addition, as shown in FIG. 3, when the vertical frame 1 is large and the displacement with respect to the mounting rail 4 is small, the partition plate 5 may be a flat plate that is not bent. 2 and 3, 10 indicates a side plate of the cabinet, and 11 indicates a rear door.

  As shown in FIG. 2, a negative electrode bar 9 is vertically supported by a support member 12 inside the vertical frame 1. Further, in parallel with the negative electrode bar 9, the positive electrode bar 8 is supported in a laminated manner at a predetermined interval via an insulating member called a cleat. The lower end portion of the DC power supply bar constituted by the negative electrode bar 9 and the positive electrode bar 8 is connected to the DC power supply unit 13 shown in FIG. The stacking direction of the DC power supply bars is preferably the depth direction of the cabinet, and the negative electrode bar is disposed closer to the door side than the positive electrode bar as shown in FIG. Since the negative electrode bar 9 has the same potential as the frame of the cabinet, it can be fixed to the vertical frame 1 by the support member 12 and does not need to be supported by an insulating member or the like.

  As shown in FIG. 2, the negative electrode bar 9 and the positive electrode bar 8 are arranged such that one bar is shifted in the width direction of the bar with respect to the other bar. In this embodiment, the negative electrode bar 9 is on the outside and the positive electrode bar 8 is on the inside. With such an arrangement, an insulation distance between the positive electrode bar 8 and the side plate 10 of the cabinet can be secured. The negative electrode bar 9 can be fixed to the mount rail 4 and does not necessarily have to be supported by the vertical frame 1.

  As described above, the negative electrode bar 9 is disposed outside the positive electrode bar 8 while being shifted in the width direction, so that an exposed portion is formed on the side of the negative electrode bar 9. In this exposed portion, a connection fixing portion 16 for fixing a connection member 15 and a connection terminal 19 described below are provided to improve the integration density of the DC power supply bars.

  The connecting member 15 is for connecting to a load such as a server to perform DC power supply, and is provided in a large number at a predetermined pitch in the vertical direction. As shown in FIG. 4, the connecting member 15 of this embodiment includes a connector 17 for connecting to a power plug drawn from a load device, a fuse unit 18, and a connecting terminal 19, and FIGS. As shown, it is supported at a predetermined position by being fixed to the negative electrode bar 9-. FIG. 7 is a perspective view from the back side of FIG. 5 and shows a state in which the connection terminal 19 is fixed to the negative electrode bar 9-.

  As shown in FIG. 8, the fuse unit 18 includes a unit main body 18a and a fuse element 18b. The fuse element 18b is detachable from the unit main body 18a, and has a structure that can be easily replaced. The unit main body 18 a is provided with a bar connection line 20 for connecting to the positive electrode bar 8 and a terminal connection line 21. For this reason, when the electric circuit of the positive electrode bar 8 → the bar connection line 20 → the fuse unit 18 → the terminal connection line 21 → the connector 17 → the load → the connector 17 → the connection terminal 19 → the negative electrode bar 9 is formed and the load is short-circuited. In this case, the fuse element 18b can be melted to block the influence on other loads. FIG. 7 shows a state where the bar connection line 20 is connected to the positive electrode bar 8.

  As shown in FIG. 9, the partition plate 5 is formed with a large number of holes 22 corresponding to the mounting positions of the connection members 15, and the surfaces of the connector 17 and the fuse unit 18 are the holes. 22 is exposed toward the inside of the cabinet. For this reason, the connection of the power plug drawn from the load device to the connector 17 and the replacement of the fuse element 18 b can be easily performed without removing the partition plate 5. Moreover, since this position is on the rear side of the cabinet, there is no possibility that an operator touches the fuse unit 18 when installing or inspecting the server from the front side. Furthermore, the fuse unit 18 is also hidden from the wiring to the load device even from the back side, and the risk of the operator touching it is reduced.

  Reference numeral 25 shown in FIGS. 2 and 7 denotes a capacitor. The capacitor 25 is effective to prevent the voltage of the DC power supply bar from temporarily changing due to load fluctuations of the server or the like and the voltage supplied to other loads from fluctuating. A plurality of capacitors 25 are preferably arranged at a predetermined interval on the DC power supply bar corresponding to the installation position of a load such as a server. If the configuration is such that it is connected to the connection terminal of the connection member 15 as in this embodiment, It is easy to correspond to the load arrangement. In this embodiment, the capacitor 25 is arranged facing away from the connector 17 and the fuse unit 18.

  As described above, since the DC power supply cabinet of the present invention has the positive electrode bar 8 and the negative electrode bar 9 that are DC power supply bars disposed in the side space 7 partitioned by the partition plate 5, the DC power supply bar is There is no pressure on the equipment storage space. Further, the vertical frame 1 and the mounting rail 4 constitute a vertical support member inside the cabinet, and the strength of the frame is not reduced. In addition, there are many advantages such as the ability to restrict access to the charging unit by the partition plate 5.
