DESCRIPTION OF THE PREFERRED EMBODIMENTS In an embedding box for a wiring device, a reinforcing plate and an arm with a claw are eliminated, and the inside thereof is widened accordingly (1).

In the plate (2) for reducing the opening area of the embedding box for wiring equipment, the back (3) was attached to the back.

In the opening (4) of the filling margin of the embedding box, a back (5) was attached to the back.

In the embedding box for wiring equipment, a gap (7) of 2 mm was provided between the screw hole insertion portion (6) for fixing the metal frame and the upper and lower side surfaces.

In the embedding box for wiring equipment, a knock hole for passing an electric wire was designed to be cut out to the board surface (8).

In the embedding box for a wiring device, the cutout groove was deepened so that the electric wire passing knock hole could be easily opened with a finger. Or a hole was made from the beginning (9).

In the embedding box for wiring equipment, a knock hole (10) for passing electric wires was also provided on the mounting surface.

In the embedding box for wiring equipment, a pedestal (11) was attached around the stud fixing screw hole so that the screw would not fall when tightened. It has a small inside diameter so that the mountain of wood screws can penetrate to some extent.

In the embedding box for wiring equipment, a part (12) having a structure for filling a gap between the surface in contact with the box and the board for the paint allowance and the metal frame was prepared.

In the case of the part (12), if there is a gap between the surface in contact with the box or the board of the filling allowance and the back of the board, a part having a structure (FIG. 6) that can be added by several millimeters is provided. It needs to be installed further. Or, conversely, there is a structure in which a long gap-filled part with a cut is cut out at intervals of several millimeters in accordance with the gap (FIG. 7). Alternatively, use a material that can be deformed and shrunk when tightened with a certain amount of torque or more, and that can adjust the thickness. Moreover, it is not an unstable material such as urethane or steel spring, but a material having a material and a structure that maintains the deformed and contracted state without returning to the original shape even when the screw is loosened after the deformation and shrinkage is used. For example, aluminum or copper is preferable as the material, and the shape includes a W shape (FIG. 8), a spiral shape, a bellows shape, and a diamond shape (FIG. 9).

FIGS. 10 and 11 show a mechanism (13) for eliminating a play in a slot of a metal frame in a component having a structure for filling a gap between a surface of a metal frame and a surface in contact with a box or a board for a paint allowance. The additions are shown. The mechanism has a protrusion (14) that is the same as or slightly thinner than the thickness of the metal frame, and the shape of the protrusion is almost the same as the long hole of the metal frame (15), and has a hole through which a screw passes in the middle. Insert the long hole of the metal frame into the protruding part of the box with a screw and apply it to the screw hole of the box.

In addition, FIG. 12 shows an example in which these functions are given to a metal frame. The box mounting hole is a round hole (16), and has a cylinder (17) on the back surface having the same length as the thickness of the board.

[0048]

According to the present invention, the inside is wider and the electric wire is better accommodated compared to the conventional embedded box for wiring equipment.

Conventional plate (2) for reducing opening area
Compared with the embedded box for wiring equipment with, the saw blade no longer gets caught when opening the board.

When opening the board for the opening (4) of the filling allowance of the embedding box, the saw blade was no longer caught by pulling as compared with the conventional case.

Since a gap (7) was created between the insertion portion of the screw hole for fixing the metal frame and the upper and lower side surfaces, the opening could be opened with a saw or the like. Gypsum board can be cut off with a cutter knife, but plywood has been very difficult to work with.

As compared with the conventional case, in the embedded box for wiring equipment, when the box is mounted later, it is not necessary to pass the electric wire through the electric wire passing knock hole, so that it is easier.

In comparison with the conventional case, in the embedding box for a wiring device, a tool is not required when a knock hole is made, so that it is easier. Since it can be easily opened, it may be inadvertently opened, but there is no problem at the time of opening, and a type in which all holes are open from the beginning is also convenient.

In the embedding box for wiring equipment, since the knocking hole (10) for passing electric wires is also provided on the mounting surface, the stud can be drilled from the knocking hole, so that an outlet or the like is added. Now, it's easy now that you have to remove the box, drill holes in the studs and the box, and then attach it again.

Compared with the conventional case, when the screw is sunk into the embedded box for wiring equipment to fix it to the stud, the pedestal (11) stabilizes the screw, so that the screw hardly falls down.

As compared with the conventional case, the gap between the metal frame and the surface of the box or painting margin in contact with the board in the embedded box for wiring equipment or the coating margin is eliminated, so that the metal frame may warp even if screws are tightened to some extent. Now, the board can be fixed firmly without bending to the back.

When the stud to which the wiring device embedding box is attached is vertically built, if the wiring device embedding box and the wiring device are attached as they are, the stud is automatically mounted vertically, which is easy.
