Abstract

PURPOSE:To facilitate operations of a cable connection, check, and maintenance by providing a terminal block at an upper part of a breaker box containing a breaker, and connecting a power supply cable to the block via a rear surface of the box. CONSTITUTION:A breaker box 7 for containing a breaker 7a is mounted at a side face of an electronic apparatus 1 via a box support 8, and a terminal block 9 is so mounted on an upper surface of the box 7 that the block 9 becomes substantially horizontal with its terminal surface. The support 8 is formed with a space which can pass a power supply cable 4 between the box 7 and the side face of the apparatus 1. The cable 4 is connected to the block 9 of an upper part of the box 7 via an interior of the support 8. Thus, since a connecting part of the cable 4 to the block is easily confirmed, operations of a cable 4 connection, check and maintenance can be facilitated.

2. Description of the Related Art Generally, an electronic device is constructed by arranging a terminal plate, which is a port for receiving a cable for power supply, inside the device, arranging a breaker on an upper part or a side part thereof, and connecting a copper bus bar between them. Has been done.

FIG. 3 is a front view of an electronic device for explaining a mounting structure of a power feeding cable according to the prior art, and FIG. 4 is a BB view in FIG. 3 and 4, 1 is an electronic device, 2 is a rack, 2'is a frame, 3 is a free access floor,
4 is a power supply cable, 5 is a distribution board / power supply device, 6 is a cable clamp, 7 is a breaker box, 7a is a breaker, 7b is a copper bus bar, 9 is a terminal board, and 10 is a cable.

[0004] The illustrated prior art is an example of a mounting portion of a power supply cable provided on a side portion of the electronic device 1, and this type of electronic device 1 is usually a frame 2'on a free access floor 3.
It is configured inside the rack 2 configured by. Since the electronic device 1 has a DC power supply for converting AC to DC, a cooling fan, etc., mounted in the rack 2, the power supply cable 4 guided from below the free access floor 3 into the electronic device 1.
The mounting area must be narrowed to reduce the floor area of the electronic device 1 and reduce the size of the device. Further, a large number of electronic devices 1 are arranged and installed on the free access floor 3.

For these reasons, the power supply cable 4 for supplying power to each electronic device 1 is mounted on the side surface of the electronic device 1 as shown in FIG. 3, and its maintenance, inspection, and operation are performed on the front surface of the electronic device 1. It is usually done from.

In FIGS. 3 and 4, the mounting portion of the power supply cable arranged on the side surface of the electronic device 1 is the power supply cable 4
The terminal board 9 which is a receiving port of and the breaker box 7 arrange | positioned at the upper part are comprised. A plurality of breakers 7 a are housed in the breaker box 7.
The power supply cable 4 is connected to the terminal board 9, and the terminal of the breaker 7a and the terminal board 9 are connected by a copper bus bar 7b. Further, the other terminal of the breaker 7a is connected to the terminal board 9.
A cable 10 drawn into the electronic device 1 is connected. The power supply cable 4 is wired from the lower part of the distribution board / power supply device 5 for supplying power to the electronic device 1 to the lower part of the electronic device 1 via the lower part of the free access floor 3, and further, the electronic device 1 Is erected from the lower part to the inside of the mounting portion of the power supply cable and connected to the terminal board 9. The power supply cable 4 is fixed by the cable clamp 6 in the rack 2 of the electronic device 1.

In the mounting structure of the power supply cable configured as described above, the power is supplied from the distribution board / power supply device 5 to the electronic device 1 by the distribution board / power supply device 5, the power supply cable 4, and the terminals. It is performed through the plate 9, the breaker 7a, and the cable 10.

[0008]

In the above-mentioned conventional technique, the terminal board 9 and the breaker box 7 are arranged not on the front surface of the electronic device 1 but on the side surface thereof, and the cable connection work and the like must be performed from the front surface of the electronic device 1. Therefore, there is a problem in that workability such as connection work, maintenance work, and inspection work is poor.

Particularly, in the above-mentioned prior art, when the mounting density of electronic devices increases and the amount of power used increases, the number of power supply cables increases due to an increase in the amount of power supply, and the mounting area of the input cable becomes narrower. There is a problem that workability such as maintenance and inspection work is further deteriorated, and in some cases, it is required to expand the mounting area of the power feeding cable.

An object of the present invention is to solve the above-mentioned problems of the prior art, to improve workability of cable connection, workability of maintenance and inspection work, and to increase the density of electronic devices. An object of the present invention is to provide a mounting structure of a power feeding cable of an electronic device, which can cope with the limitation of the mounting area of the power feeding cable and the increase of the number of input cables accompanying the increase of the power supply amount.

[0011]

According to the present invention, the object is to store a breaker in a breaker box, and
This is achieved by installing a terminal board on the top of the breaker box and connecting a power supply cable to the terminal board through the back surface of the breaker box.

[0012]

[Operation] By passing the power supply cable through the back of the breaker box, the power supply cable
Since it is not placed in the front or the like, it is possible to prevent the breaker operation from being obstructed, and it is possible to easily perform maintenance and replacement of the breaker. The packaging density can be improved.

Further, by installing the terminal board on the top of the breaker box, the surface of the terminal board can be placed in a substantially horizontal state, and the connection portion of the power supply cable can be easily seen from the upper part of the electronic device. Connection work, maintenance,
Workability such as inspection work can be improved.

Further, according to the present invention, the unit having the terminal board and the breaker box having the same structure can be appropriately arranged on the opposite surfaces, whereby the power feeding cable can be mounted without expanding the mounting space. The number can be further increased.
