Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distribution board unit, and more particularly, to a distribution board unit that can be stored in a rack for storing equipment.

[0002]

2. Description of the Related Art When power is supplied to information equipment such as a server computer, a hub, or a router installed in a rack, an uninterruptible power supply (UPS) is provided to protect the equipment from power failure or momentary power failure. And this UPS
Power is supplied through. In this case, conventionally, as shown in the wiring diagram of FIG. 4, wiring is performed from the secondary side of the main breaker 4 of the distribution board 16 to the input terminal of the UPS 14, and the UPS 1
4 returns to the branch circuit primary side of the distribution board 16 from the output terminal,
Power is supplied by wiring to the plurality of racks L1 to L8 from the secondary side of the branch breaker 6 respectively. In each rack, an outlet for wiring from the distribution board 16 is provided, and each device in the rack receives power through the outlet.
FIG. 4 shows a case where the UPS is a rack-mount type that saves space.

[0003]

However, in the case of the above configuration, wiring must be reciprocated between the distribution board 16 and the rack L1 having the UPS 14, and wiring for supplying power must also be laid. In addition, wiring was troublesome, and the amount of electric wires used was large. In view of the above problems, it is an object of the present invention to provide a rack-mountable power distribution unit that simplifies wiring between a power distribution panel and a rack and minimizes the amount of electric wires used. I do.

[0004]

According to a first aspect of the present invention, there is provided a box-shaped storage portion having an open front surface, and rack mounting and fixing portions at left and right ends of the storage portion. The internal equipment of the distribution board is arranged to be operable from the front in a case where the mounting pieces are protruded and rack mountable.

According to a second aspect of the present invention, in the first aspect of the present invention, an input / output terminal block connected to the internal unit of the distribution board is provided on the back surface of the main body.

According to a third aspect of the present invention, in the second aspect of the present invention, the input / output line terminal block is provided so as to be inclined so that the input / output line direction is obliquely rearward.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 and 2 show an example of a distribution board unit according to the present invention, and FIG.
1B is a front perspective view, FIG. 1B is a rear perspective view, and FIG.
Is a front perspective view of a state in which a cover is provided on the front,
A distribution board device is provided in the case.

A case 1 comprises a rectangular box-shaped storage section 2 having an open front and mounting pieces 3 mounted on a rack protruding from the front left and right sides thereof. Is a main body breaker, 5 is a feed breaker, and 6 is a branch breaker. A terminal block 8 is attached to the main body 1 via a base plate 9 in an inclined posture on the rear surface of the main body, and reference numeral 10 denotes an input / output line connected to the terminal block. The main unit such as the master breaker and the branch breaker may be a general-purpose one. However, by using a miniaturized one for a home distribution board, the overall dimensions can be reduced to be small and compact. Further, a cover 11 in which an operation window 12 for exposing only the operation unit of the inner machine is formed in the open front surface of the case is detachably provided,
It is formed so that the operation unit and the charging unit are not accidentally touched.

FIG. 3 is a wiring diagram showing a connection state of a rack mount type distribution board unit.
The rack L1 is stored in the rack L1 together with the PS14.
1, and power is supplied to racks L2 to L8 in which information devices such as server computers, hubs and routers are stored. The wiring is wired from the secondary side of the main breaker 4 to the input terminal of the UPS 14, returns from the output terminal of the UPS 14 to the primary side of the branch circuit of the distribution board unit 13, and supplies power to each rack from the secondary side of the branch breaker 6. In each rack, power is supplied from a distribution board via an outlet (not shown). The feed breaker 5 is used to supply power to another rack via a distribution board.

As described above, the distribution board can be installed in the rack by using the rack mount type, and if it is installed in the same rack as the UPS, the distance of wiring from the main breaker to the branch breaker via the UPS can be minimized. And the amount of electric wire used can be reduced. In addition, since it has a terminal block, it is possible to easily perform wiring in / out work,
By providing with an angle, even if it is arranged at the bottom of the rack, it is possible to secure a connection space and make it easy to perform incoming and outgoing wire work,
If the base plate 9 is installed upside down on a rack, it is also possible to carry out the incoming and outgoing wire work from above. In addition, since the distribution board is housed in the rack, a space for installing the distribution board is not required, and the space can be effectively used.

[0011]

As described above in detail, according to the first aspect of the present invention, since the distribution board can be installed in the rack, the number of wirings between the distribution board and the rack is reduced, and the wiring distance is minimized. Can be kept. In addition, if an internal unit of a mass-produced home distribution board is used as a distribution board unit, the size can be reduced at a low cost, and the space for installing the distribution board can be saved.

According to the second aspect of the present invention, in addition to the effects of the first aspect of the present invention, since the terminal block is provided on the back surface, the work of inputting and outputting the wiring can be easily performed.

According to the third aspect of the present invention, in addition to the effect of the second aspect of the present invention, since the incoming and outgoing line work is performed diagonally from the rear instead of from below, a connection space can be secured and the in and out line work can be easily performed.
