However, when the name of the load device, the circuit number, the power supply information, etc. are indicated using the display name plate, the display name plate is used as the main body cover in the process of attaching the name plate during the assembly process of the distribution board. It is necessary to attach it, but there is no index for the attachment position on the main body cover of the distribution board, and there is a problem that it is difficult to determine the attachment position. At the time of sticking, if the sticking is distorted even a little, there is a problem that the distortion is conspicuous because it is not parallel to the rectangular distribution board outer shell and the aesthetic appearance is spoiled. In addition, there is a problem that the process cost of the sticking work of the display name plate increases, for example, it becomes necessary to prepare a special sticking jig for sticking in parallel.

When the display name plate is tilted, it becomes necessary to replace the name plate, which may lead to a decrease in work efficiency.

On the other hand, when the name, circuit number, power supply information, etc. of the load device are indicated using the display card, the display card is mounted at a predetermined mounting position of the display card to complete the mounting. It is necessary to dispose the display card supporting means for mounting the display card on the main body cover of the above, and there is a problem that it is costly to newly provide a structure for mounting the display card.

Therefore, according to the present invention, even when the name of the load device, the circuit number, the power supply information, etc. are indicated by using the display name plate without using the display card, the main body does not reduce the work efficiency at the time of assembling the distribution board. The structure of the cover is also simple, and the purpose is to provide a distribution board that does not increase the manufacturing cost of the main body cover.

The distribution board according to one aspect of the present invention includes a resin main body cover having an opening for exposing a handle for operation provided in each of the plurality of branch switches, and the main body cover is said to have an opening. In the vicinity of the opening, a circuit information display unit that clarifies the position where the display name plate corresponding to the arrangement position of each branch switch is attached and a circuit information display unit that displays power supply information are on the surface of the main body cover. The circuit information display unit, which is provided integrally with the main body cover on the surface side in advance by resin molding that digs down one step from the top, and that clarifies the position where the display name plate is attached, is resin molded from the surface of the circuit information display unit. The load circuit number is formed by the above, and the circuit information display unit that displays the power supply information is characterized in that the power supply display is formed by resin molding that is dug down from the surface of the circuit information display unit.

According to this aspect, since the circuit information display unit is integrally provided on the main body cover by resin molding, the display name plate is displayed on the predetermined circuit information when the display name plate is attached to the main body cover. The sticking work can be performed stably along the part. Therefore, the work efficiency does not decrease.

Further, since the circuit information display unit is provided in advance on the main body cover by molding, the structure for displaying the circuit information is not complicated. Therefore, the main body cover can be provided without increasing the manufacturing cost of the main body cover.

Further, in the distribution board, the circuit information display unit may be provided on the front surface or the back surface of the main body cover. As a result, the circuit information can be displayed on both the front surface side and the back surface side of the main body cover, and the circuit information can be easily grasped by both the builder and the resident.

Further, in the distribution board, the circuit information display unit may be provided with a load circuit name corresponding to the branch switch. As a result, the work of attaching the display name plate can be omitted, and the display name plate can be attached only to the portion different from the preset load circuit name, so that the work efficiency can be improved. Further, when the resident changes the name of the load circuit, the convenience can be improved because it can be dealt with by changing the display name plate only for that part.

Further, in the distribution board, the circuit information display unit may be provided with a load circuit number corresponding to the branch switch integrally molded with the main body cover. As a result, the work of attaching the display name plate can be omitted, and the display name plate can be attached only to the portion different from the preset load circuit number, so that the work efficiency can be improved. Further, when the load circuit number is changed in the resident, the convenience can be improved because the display name plate can be replaced only in that part.

Further, in the distribution board, the circuit information display unit may be provided with a power supply display corresponding to the branch switch integrally molded with the main body cover. As a result, the work of pasting the display name plate can be omitted, and the display name plate can be pasted only in the portion different from the preset power supply display, so that the work efficiency can be improved. In addition, it is unlikely that residents will change the power supply display, but when changing the power supply during aged inspections, it will be possible to respond by attaching a display name plate to that part in the future. Convenience can be improved.

According to the present invention, even when the name of the load device, the circuit number, the power supply information, etc. are indicated by using the display name plate without using the display card, the work efficiency is not lowered at the time of assembling the distribution board. The structure of the main body cover is also simple, and it is possible to provide a distribution board that does not increase the manufacturing cost of the main body cover.
