[0003]
In the above installation work, the plurality of electric wires 2 are pre-wired so that they pass through the wall and run over the ceiling or under the floor to other necessary equipment, and are drawn into the distribution board from the opening of the wall 3 It is extended with a length margin so as to be connected to a predetermined plurality of branch breakers.
[0004]
The distribution board 4 with the cover 6 removed is applied to the wall surface so as to cover the opening 3 in a state where the plurality of electric wires 2 are drawn into the distribution board from the electric wire drawing opening 8. Fixed to the wall. Thereafter, the plurality of electric wires 2 are routed through the internal wiring space of the distribution board 4 toward the terminal portion of the predetermined breaker, cut at an appropriate length, and the covering of the connection portion to the breaker terminal is removed to the breaker terminal. Connected. (For example, FIG. 4 of patent document 1 represents drawing of the electric wire in the distribution board.)
[0005]
Thereafter, the cover 6 is attached to the distribution board 4 fixed to the wall surface, and the construction is completed. After that, until the resident of the house actually uses electricity, the power company may separately install a power limiter on the residential distribution board, but this is a burden for the power company. .
[0006]
In recent years, electrical work in homes and the like has been required to be simplified in order to reduce the cost of the homes, and it is desirable to simplify the installation work of the distribution board. However, the construction by the above method is complicated, the process of drawing the electric wire in the wall, the process of processing the wall surface, the process of drawing the electric wire from the opening of the wall surface, the process of cutting the electric wire, the process of drawing the electric wire into the distribution board , The process of fixing the distribution board to the wall surface, the process of drawing the electric wire in the distribution board and connecting the electric cable to the breaker, respectively, require work that requires specialized techniques.
[0007]
In view of this, there has been proposed a method for simplifying the construction by connecting the distribution board and the electric wire with a connector. (For example, the content of the claim of patent document 1 and the content of the request of patent document 2)
[0008]
However, Patent Document 2 is designed so that the distribution board for temporary construction can be electrically attached to and detached from the main line, and the connection is limited to the main line only, and the connection to the load side of the distribution board can be touched. Not. In the method according to Patent Document 1, it is necessary to connect a plurality of connectors such as a main breaker and a branch breaker to the wall surface of the distribution board at the same time. Since the current carrying capacity of the distribution board breaker is as large as several tens of amperes, even a connector corresponding to one breaker requires a considerable insertion force, and it is not practical to connect multiple connectors at once.

DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram for explaining a distribution board using a first embodiment of the present invention. It includes a box 101, a main breaker 102, a plurality of branch breakers 103 to 106, a connection conductor 107, a surface side cover 108, and the like. Reference numerals 109 to 113 denote connectors which are fixed to the side surface portion of the box 101 with the connection portions exposed, and are respectively identified as M and B1 to B4 so that they can be recognized from outside the box. Connectors 109 to 113 are connected to electric wires 115 to 118, respectively, and the other ends of the electric wires 115 to 118 are connected to electric wire connecting terminals of the breakers 103 to 106. The other end of the wire 114 is cut to an appropriate length in the vicinity of the position of the wooden board 119 in the box 101.
[0016]
Reference numeral 120 denotes an attachment means for fixing the box to the wall surface, and is fitted to the attachment receiver 121 or the like previously fixed to the wall surface with one touch. The cover 108 can be attached to and detached from the box 101 by screws or fitting. Note that the above-described box 101 and cover 108 do not have a hole through which the electric wire and the charging unit are exposed.
[0017]
The above distribution board 100 is attached to the wall surface as shown in FIG. Assume that the wires 201 to 205 connected to the distribution board are connected to connectors 206 to 210, which have been previously identified in the same manner as the distribution board, and wired from the ceiling to the vicinity of the distribution board mounting position. . In the state as described above, the attaching process is first performed by a. The attachment receiver 121 is attached to the wall surface mounting position of the distribution board with screws 122 or the like. b. Next, the duct case 301 is attached to the wall surface with screws or the like as necessary. c. Next, the distribution panel 100 is fixed by pushing the attachment means 120 against the attachment receiver 121. d. Next, the connectors 206 to 210 of the electric wires 201 to 205 are connected to the connectors 109 to 113 on the distribution board 100 side according to the identification. e. Finally, the duct cover 302 is attached to the duct case 301 with screws or the like, and the process is completed.
[0018]
The steps c and d may be interchanged, and the duct case 301 may be integrated with the attachment receiver 121. Further, the duct case 301 and the duct cover 302 may be omitted. This is because if the connector mounting surface of the distribution board 100 in the figure is brought into contact with the ceiling surface, the wires 201 to 205 are hidden on the ceiling surface, and such mounting is also conceivable. In addition, in the type in which the wall surface of the house is separately standardized and produced at the factory, the attachment receiver 121 does not need to be specially provided if it is preliminarily molded on the wall surface, and there is also a method of attaching it in advance at the factory.
[0019]
This completes the installation work of the distribution board. However, for the 114 wires shown in FIG. 1 described above, after the installation work of the distribution board together with the 122 wires, the power company installed a current limiter (contract breaker) on the wooden board. When attaching to 119, the tip is cut, the coating is peeled off, and the current limiter terminal is connected. Depending on the electric power company, the current limiter may not be required. In this case, the wire 114 in FIG. 1 may be connected to the wire connection terminal of the breaker 102 in advance.
[0020]
FIG. 3 is a diagram of a second embodiment according to the present invention. The difference from the first embodiment is that no connector is attached to the side surface of the box 401, and the electric wires 402 to 406 are drawn out from the box 401, and the connectors 407 to 411 are provided at the tips thereof. Is connected. Identification (M, B1 to B4 in the figure) is made on an electric wire or a connector.
[0021]
In the second embodiment, the mounting is performed as shown in FIG. 4, but the mounting order is substantially the same as the mounting in the first embodiment (FIG. 3). In other words, the electric wires 501 to 505 already wired indoors are not connected to the connectors 109 to 113 of the box 101 in FIG. 1 but to the connectors 407 to 411 of the electric wires 402 to 406. The place of connection is different.
[0022]
Incidentally, the electric wires 201 to 205 and 501 to 505 are not connected to the connectors 206 to 210 and 506 to 510 at the site, but are processed in advance at a factory or the like and brought into the site.
[0023]
In the above description of FIGS. 1 to 4, the distribution boards 100 and 400 and the ducts 301 and 302 have been described with the impression that they jump out onto the wall surface, but if necessary, the wall surface is recessed. The surface can be the same as the wall surface.
[0024]
Furthermore, in the above example, the side surface for attaching the connector or the electric wire to the distribution board is the side surface on the ceiling side, but the side surface, the bottom side surface, or the back side surface may be used as long as it is not the surface. The connector to be used is illustrated with the assumption that the male and female are collectively fastened with screws after the electrodes are connected with multiple poles. It may be a group of several breakers. The fastening may be a plug-in type that is not screwed but is provided with a stopper. The wires 115 to 118 and 402 to 406 are illustrated as multi-core cables, but single wires may be used.
[0025]
【effect】
As described above, according to the distribution board of the present invention, the installation operator can handle the distribution board as one unit without removing the cover of the distribution board and without being aware of the functions and wiring inside the distribution board. , The distribution board can be fixed to the wall easily by one touch, independent of the connection of the connector, by the attachment means. In addition, there is no need to pull the wires into the distribution board at the site, and there is no need to cut or remove the covering to connect the wires to the breaker. You do not need to know which breaker to connect to, and you can fit the connectors together according to the identification. Therefore, it does not require specialized knowledge and technology, and since it is possible to independently connect the wires and fix the distribution board to the wall surface, it can be mounted practically without requiring any special force.
