Description

    The present invention relates to a distribution board in which an electric device such as a main breaker or a branch breaker is placed on a base and the electric devices are connected by a conductive bar.

    In the distribution board 31 in the prior art, a main breaker 33 and a branch breaker 34 are arranged on a base 32, and these breakers are connected via a conductive bar. When the number of branch circuits is large, the branch breakers 34 are arranged in two upper and lower rows. Wiring of the branch breakers 34 to the load side is performed on the upper row of the branch breakers 34 in the upper row and on the lower side of the branch breakers 34 in the lower row.

As shown in FIG. 2 , the wiring is passed to the back surface 35 of the distribution board 31. Or as shown in FIG. 3 , the notch 37 is provided in the side plate 36 of the upper side of the base 32 of the electricity distribution panel 31, and wiring is passed through the inside of a wall surface, or a ceiling. An opening was provided in the wall or ceiling on the back surface of the base 32, and wiring was made through this opening.

However, according to the above prior art, as shown in FIG. 4 , depending on the position of the distribution board, the distribution board may have to be placed directly under the ceiling. It is difficult to work, and in particular, the wiring on the upper side of the branch breaker may not be visible.

    In addition, the wiring work must be performed in a limited space on the base, which has the disadvantage of poor workability.

Therefore, the present invention aims to improve the workability such as connection by changing the arrangement of the electrical equipment on the base, and the structure of the distribution board has a branch breaker on the base and a long side on the floor surface. For the wiring at the position adjacent to the base on which the electrical equipment is placed on the wall to which the distribution board is mounted, with a plurality of branch breakers arranged vertically and with side walls provided with notches The cover is rotatably attached to the base via a hinge and has a size including the base and the opening .

In the distribution board according to the present invention, the branch breakers are arranged horizontally in the long side with respect to the floor surface, and the plurality of branch breakers are arranged in tandem, and the side panel is provided with a notch. Even when installed, the work can be performed while observing the terminal portion of the breaker, so that there is an advantage that the wire connection work can be surely performed.

    In addition, an opening for wiring is provided at a position adjacent to the base on which the electrical equipment is placed on the wall to which the distribution board is mounted, and the cover is rotatably attached to the base via a hinge. Since the size includes the base and the opening, wiring can be performed in a space adjacent to the terminal of the breaker, not on the base where the space is conventionally limited, and the workability is greatly improved. Moreover, since the opening provided in the wall is covered with a cover, the opening work can be easily completed.

    The purpose of improving workability such as wiring was realized with the minimum number of parts and effective use of the limited space of the base.

    An embodiment of a distribution board according to the present invention will be described with reference to the attached drawing of FIG.

The distribution board 16 is configured by arranging electrical devices such as a main breaker 12 and a branch breaker 13 on a base 11 and covering the front surface with a cover 17 . The branch breakers 13 have long sides arranged horizontally with respect to the floor surface, and a plurality of branch breakers 13 are arranged vertically, and are stored on a base having the same vertical dimensions as a conventional distribution board.
The base 11 is provided with a conductive bar for connecting the electrical equipment such as the main breaker 12 and the branch breaker 13 to the electrical equipment, and a gutter space for wiring from the load side terminal portion 14 of the branch breaker 13 to the load is used as a base. It is not provided on the table 11. An opening is provided in the wall surface near the base 11 and wiring is performed at the opening. A cutout 15 is formed in the side surface portion of the base 11 for wiring to an opening provided on the wall surface.

Since the branch breakers 13 are arranged vertically, the horizontal dimension of the base 11 can be shortened, and the restriction on the installation location is reduced.
In addition, since the notch 15 is provided beside the terminal portion 14 of the branch breaker 13, the operator can work while observing visually compared to the case where there is a gutter space above the branch breaker 13, so that the work can be performed reliably and easily. Is greatly improved.

The front surface of the base 11 is covered with a charging part by a cover 17 provided with an operation hole through which an operation handle of the breaker can be projected. Furthermore, a door body can be attached. The cover 17 is rotatably attached to the base 11 via a hinge, and is formed in a size that can be covered, including not only the base 11 but also an opening provided in the vicinity of the base 11. .

The opening for wiring is not provided on the base 11, but is provided directly on the wall surface in the vicinity of the base 11. However, the cover 17 is provided larger than the base 11, and the base 11 is also provided with an opening provided on the wall surface. Since it is covered, the appearance of the notch 15 and the opening of the wall surface of the base 11 is not affected even if it is not precise. Therefore, it is possible to simplify the opening processing operation.

    By arranging the branch breakers vertically, it is possible to effectively utilize the limited space of the base, and the overall size of the distribution board can be reduced. It can also be applied when you want to place a board.
