Description

[Detailed description of the invention] The present invention is a wiring device that uses a paint allowance cover attached to the opening of the box to separate high-current wires and low-current wires stored in the same box. The present invention relates to a partition device.

Conventionally, to bury and fix a box in a concrete wall, the following steps were performed. First, as shown in FIG. 1, the paint allowance cover A is attached to the opening surface of the box B. Paint allowance cover A
The box is usually formed of a frame having a through hole I into which a wiring device is inserted as specified in Japanese Industrial Standard C8435, and is attached to the opening surface of the box to open the box in the shape of the through hole I. The through hole I is smaller than the opening of the box B.

After temporarily fixing the box B with such a coating allowance cover A attached to the support steel reinforcement (not shown) and leaning the concrete formwork E, screw the female screw D provided in the center of the bottom wall C of the box B into the box B. Natsuto G on one end
Screw in the bolt F to be screwed into the formwork E from the outside,
By tightening the nut G, the box B was pulled and the paint allowance cover A was tightly fixed to the inner surface of the formwork E. This drawing operation must be performed in order to prevent concrete from flowing into the box during concrete pouring, and cannot be omitted when the box is buried in concrete. In this case, the female screw D is placed in close contact with the inner surface of the formwork E through the through-hole I of the coating allowance cover A attached to the box B, so that the inner wall of the box B can be drawn with equal force. It must be located at the center of the bottom wall C of box B. After that, concrete is poured and the box B with the coating cover A attached is buried and fixed within the concrete wall.

On the other hand, conventionally, when installing strong current wires and low current wires in the same box, a partition plate must be installed in the box to separate the strong current wiring devices and the weak current wiring devices according to the electrical equipment technical standards. Therefore, as shown in FIG. 2, a box B' is provided with an engaging part (not shown) of a partition plate in the center of opposing side walls H, and a box B' is engaged with the engaging part. Partition plate K installed in the center of box B'
The wiring equipment for strong currents and the wiring equipment for weak currents were partitioned and housed in box B' using .

However, in order to partition and store strong current wiring devices and weak current wiring devices in the same box, there are the following problems when using box B' having the engagement portion of the conventional partition plate K. It was hot.

When box B' is buried in a concrete wall, the through hole I of the coating allowance cover A is
Since the opening of box B' is smaller than the opening of box B', the partition plate K cannot be installed inside box B' after the painting allowance cover A is attached to the opening of box B'. When performing concrete burying work, the partition plate K must be installed in advance in the box B' before installing the paint allowance cover A. For this reason, the partition plate K installed in advance in box B' blocks the female screw provided in the center of the bottom wall of box B', so the box B' is pulled in and the paint allowance cover A is shaped. It was not possible to place the wires in close contact with the frame E, and during concrete pouring, concrete often flowed into the box B', making it impossible to install wiring devices. Furthermore, box B′,
When the box B' is buried in concrete or hidden in a wall, etc., the inside of this box B' is partitioned with a partition plate K. Since the through-hole I of the coating cover A is formed smaller than the opening of the box B', the coating After box B' with cover A attached is buried in concrete in the wall or hidden, partition plate K should be installed in box B' or partition plate K previously installed in box B' should be removed. I can't. For this reason, the worker is forced to limit the work order such as that the partition plate K must be installed in the box B' before installing the paint allowance cover A in the box B'. Due to the limitations, there were problems such as forgetting to install the partition plate K in the box B' or incorrectly installing it, which could not be corrected later. Also,
Due to the limitations of the work procedure mentioned above, there may be cases where it has not yet been decided whether or not to install the partition plate K in box B' when burying or concealing box B' in concrete.
Even when there was a change in the installation of the partition plate K after the box B' was buried in concrete or concealed, there was a problem in which the workers were unable to carry out the corresponding work.

In view of such conventional problems, the present invention is designed to allow the installation of a partition plate inside the box even after the box with the coating cover attached to the opening is buried in a concrete wall or hidden within the wall. By making it possible to remove the partition plate that has been installed in the box in advance, we aim to eliminate all the problems of the conventional method and improve the conventional partitioning work between wiring devices within the same box. It is something to do. That is, the present invention has a through hole into which a wiring device is inserted, and a wiring device fixing portion provided opposite the periphery of the through hole for fixing the wiring device, and is attached to the opening surface of the box. and a partition plate that stands upright inside the box to separate the wiring devices fixed to the paint cover and housed in the box. The periphery of the through-hole is provided with a holding part that holds the partition plate parallel or perpendicular to the axis of the painting, and the partition plate has a width that allows it to be inserted into the through-hole of the painting allowance cover, and is held in the holding part of the painting allowance cover. It is an object of the present invention to provide a partitioning device between wiring devices housed in a box, which utilizes a coating allowance cover which is characterized by having a height that allows the box to be installed upright within the box.
