DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distribution board.

[0002]

2. Description of the Related Art Conventionally, in the case of installation in a building or the like, FIG.
As shown in the figure, the cables are wired using the cable rack 1 in the electric room, and the distribution board 2 sealed with a box is provided.
Power distribution is being carried out.

[0003]

For this reason, the wiring connection in the distribution board 2 is performed by opening the front door 2A.
Since the opening area of the wiring space on both sides is small, the connection with the internal unit must be done by groping, and there is a problem that workability is very poor. Door 2
Since the display unit of the circuit name is provided on the A side, it is difficult to perform the wiring operation while looking at the display unit 4 when performing the wiring operation with the door 2A opened, and the workability is also poor in this regard. .

The invention according to claim 1 has been made in view of the above-mentioned problems, and an object of the invention is to provide a distribution board which can easily perform wiring work in the distribution board. In addition to the object of the first aspect of the present invention, in the wiring operation, the circuit for performing the wiring connection can be performed while looking at the display unit, so that there is little possibility of erroneous connection. An object of the present invention is to provide a distribution board that can perform work.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, an inner unit such as a circuit breaker or a relay is mounted on a central portion by an inner unit mounting plate and wiring is provided on both sides. in distribution board provided with the use space, entering the internal unit in said vessel
And attaching a front cover for covering the power terminal side and the operating unit, the side surface portion and the front portion and the vertical piece and a horizontal piece and the internal unit of an edge of an L-shaped two cover vertical piece of the respective configuration in respectively openably and pivotally supported on both sides of the mounting plate, the output terminal of the internal unit in crosspiece of the covers
It covers the side surface .

[0006] According to a second aspect of the present invention, in the first aspect, it is provided with a display portion of the circuit name to the surface of the front cover.

[0007]

In accordance with the Thus to the present invention, a side surface portion and the front portion longitudinal piece and crosspiece and in each of one side edge of the vertical piece of an L-shaped two cover constituting the internal unit mounting plate Both sides are pivotally supported so that they can be opened and closed, and the side of each cover covers the output terminal side surface of the internal unit.
By opening as a heart, at both ends of the distribution board,
Open the side and front to increase the internal wiring space.
Can be exposed and opened
When wiring work to the output terminal of the internal unit, the space for the operator to move and move is large, and the output terminal position of the connected internal unit can be easily seen from the outside . Workability is improved.

A circuit name is displayed on a surface of the front cover.
Since parts in which the provided, to see the display section of the front cover from the operator even with open cover of both side ends
The output terminal of the internal unit
Wiring connection work to the
This reduces the amount of work and enables efficient work.

[0009]

The present invention will be described below with reference to examples. The distribution board of the present embodiment utilizes the cable rack 1 constructed by bridging the horizontal frame 1B between the parallel vertical frames 1A, and as shown in FIGS. Vertical frame 1
A, fixing the inner unit mounting plate 7 on the surface of the cable rack 1
All of the space inside is secured as a wiring space for wiring cables for the main line.

That is, the vertical frame 1A on both sides of the cable rack 1
The U-shaped side fittings 5 are respectively fitted to the upper, middle and lower portions of the outer side surface and fixed with bolts and nuts, and the horizontal frame 6 is passed between the paired side fittings 5 on both sides. And fix it with bolts.
, And the equipment mounting plate 9 is fixed on the midsole base 8 via a mounting base 19. Thus, the device mounting plate 9 and the midsole base 8 constitute the inner device mounting plate 7.

Wiring ducts 10 are provided on the stepped flat surfaces on both sides of the midsole base 8, and the wiring ducts 10 serve as wiring spaces for wiring in the distribution board. Hinges 12 are provided on both side edges of the midsole base 8 to pivotally open and close the lower ends of the vertical pieces 11A of the protective cover 11 having an inverted L-shaped cross section. In a state where the horizontal piece 11B is rotated so as to be parallel to the midsole base 8 as shown in the drawing, the protective cover 11 is attached to the fixing screw portion 18 provided on the mounting base 5 by the horizontal piece 1B.
1B can be fixed with fixing screws 17 screwed from the surface of the protective cover 11 on both sides.
And the horizontal pieces 11B, 11B of the protective covers 11, 11 on both sides.
And a front cover 13 that covers a part of the inner unit 3 attached to the equipment mounting plate 9 and constitutes a front cover. The front cover 13 has cutout windows 14 on both sides for exposing the operation unit and the like of the inner unit 3 and a display unit 4 for displaying an internal circuit. Also, a vertical piece 11A of the protective cover 11
Is a cover that covers the side of the distribution board.

Further, an upper surface protection plate 15 and a bottom plate 16 are fixed to the upper and lower end portions of the midsole base 8, respectively, and the upper and lower ends of the front cover 13 are mounted on the surfaces of the upper surface protection plate 15 and the bottom plate 16. doing. Thus, in this embodiment, the space in the cable rack 1 surrounded by the cable rack 1 attached to the wall X and the midsole base is a wiring space for trunk wiring cables.

When wiring inside the distribution board unit, the fixing cover 17 is removed and the protective cover 11 is turned to the side by 90 degrees to rotate the protective cover 11 from the inner unit 3 to the part where the wiring duct 10 is provided. Is open, the terminals of the internal unit 3 are clearly visible from the outside,
In addition, a sufficient work space can be secured when the connection work is performed by inserting the hand of the worker inside, and the workability is improved. Protective cover 1
Since the display unit 4 of the front cover 13 can be easily seen by an operator with the unit 1 opened, wiring connection can be performed while checking the circuit, and erroneous connection can be reduced.

[0014]

The invention of claim 1, wherein according to the present invention, in wearing the inner vessel mounting plate of the circuit breaker and internal unit such as a relay Hisashi Naka portion provided with wiring space on both sides distribution board, the Inner organ
Attach the front cover to cover the input terminal side of the internal unit and the operation unit
And, pivotally to one side edge of the side surface portion and the front portion and the vertical piece and a horizontal piece with an L-shaped two cover vertical piece that respectively consists of a freely respectively open on both sides of the inner vessel mounting plate, Inner unit with horizontal piece of each cover
Since is obtained so as to cover the surface of the output terminal side,
By opening the cover around the pivot point with the inner unit mounting plate , the side and front of
Open the surface to expose the internal wiring space.
Can be released to the output terminal of the internal unit at the construction site
When performing the wiring work, the space for the operator to put his hand in and move it is large, and the position of the output terminal of the internal unit to be connected can be easily seen from the outside .
Workability is improved.

[0015] According to a second aspect of, the inventor smell of claim 1, since is provided with a display portion of the circuit name to the surface of the front cover, the display of the front cover in the opened state of the cover The part can be seen from the operator, so that the wiring work to the output terminal of the internal unit becomes possible with reference to the circuit of the display part, as a result, the risk of incorrect wiring is reduced,
Efficient work can be performed.
