However, in the conventional air-proof and dust-proof box, the insulated wires are individually passed through the air-proof and dust-proof box one by one as described above, and individually sealed, so that the workability is improved. There is a problem that is very bad.

An object of the present invention is to provide an air-proof / dust-proof box with improved workability of air-proof / dust-proof construction of wiring equipment and a wiring device using the same.

[0016]

Means for achieving the object:
The dustproof box includes an airproof / dustproof box main body; wall mounting means for mounting the airproof / dustproof box main body on the wall under the airproof / dustproof; and a mounting frame mounting means disposed on the airproof / dustproof box main body. Wiring lead-in means for drawing wiring under the air-proof / dust-proof inside the air-proof / dust-proof box main body.

In the present invention and each of the following inventions, definitions and technical meanings of terms are as follows unless otherwise specified.

The material of the air-proof / dust-proof box is not limited as long as it can be attached to the wall under the air-proof / dust-proof. However, it is desirable that the contact surface with the wall surface be soft, since the contact with air and dust is easy.

On the other hand, since the mounting frame is attached to the wall surface via the air / dustproof box main body, the air / dustproof box main body needs to have an appropriate strength. Therefore, a double structure in which a core material such as metal or synthetic resin is covered with rubber can be provided.

The wall mounting means may have any configuration as long as the air / dust proof box main body can be mounted on the wall under the air / dust proof. For example, a flange can be formed on the opening surface of the air-proof / dust-proof box main body, and the flange can be brought into contact with the surface of the wall and fixed with screws or the like. Further, the air-proof / dust-proof box main body can be attached to the wall so as to sandwich the wall surface as described later.

The mounting frame mounting means is provided on the air-proof / dust-proof box main body and mounts the mounting frame. Like a commonly used wiring box, a boss can be integrally provided on the inner surface of the air / dust proof box main body, and a nut having a box screw hole can be embedded in the boss.

A locking claw having a box screw hole formed outside the upper and lower sides of the main body of the air-proof and dust-proof box is disposed so as to be able to move back and forth while restricting rotation, and a box screw inserted into the mounting frame is provided. It is inserted into the locking claw via the flange of the airproof / dustproof box body, and the locking claw is displaced along the box screw toward the back of the wall with the rotation of the box screw. By holding the wall with, the air / dust proof box main body can be attached to the wall under the air / dust proof.
In this case, the mounting of the airproof / dustproof box and the mounting frame are performed simultaneously, so that the mounting frame mounting means and the wall mounting means are integrated.

The wiring lead-in means may have any configuration as long as the wiring is drawn under the air-proof / dust-proof inside the air-proof / dust-proof box main body. For example, an insertion hole for inserting the outer sheath portion of the terminal of the F cable can be formed in the air-proof / dust-proof box main body, and the insertion portion can be sealed.

Further, the terminal block is integrally mounted on the main body of the air-proof / dust-proof box under the air-proof / dust-proof, and the insulated wires on the indoor wiring side are connected from the outside of the air-proof / dust-proof box. It is also possible to configure so that the electric wires are connected from the inside.

Thus, in the present invention, it is not necessary to seal the insulated wires of the F cable one by one, so that the workability is good.

Further, since the air-proof / dust-proof box is also used as the wiring box, the wiring box becomes unnecessary, so that the structure is simple and the workability is further improved.

The airproof / dustproof box according to the second aspect of the present invention
An air-proof / dust-proof box main body; wall mounting means for mounting the air-proof / dust-proof box main body on the wall under the air-proof / dust-proof; mounting frame mounting means disposed on the air-proof / dust-proof box main body;
Wiring lead-in means for pulling the cable under the air-proof / dust-proof inside the air-proof / dust-proof box main body including the outer sheath portion.

If the terminal of the F cable can be pulled in including the outer sheath and the drawn-in portion can be sealed,
Although any structure may be used, for example, a structure capable of holding a sealing material is desirable, and for that purpose, an F cable insertion hole having a certain length can be used.

Thus, the structure of the present invention is further simplified.

The air-proof / dust-proof box according to the third aspect of the present invention
Air-proof and dust-proof box body; wall mounting means for mounting the air-proof and dust-proof box body on the wall under the air-proof and dust-proof; mounting frame mounting means arranged on the air-proof and dust-proof box body; indoor wiring side With the wire insertion hole on the outside of the air- and dust-proof box body and the wire insertion hole on the wiring device side inside the air- and dust-proof box body, the terminals arranged on the air- and dust-proof box body Wiring lead-in means comprising a table;
It is characterized by having.

In the present invention, if the terminal block is air-proof and dust-proof, it is only necessary to connect the electric wire to the terminal block, so that the workability is further improved.

According to a fourth aspect of the present invention, the wiring device is mounted on a wall surface.
It is characterized by comprising: a dustproof box; a mounting frame mounted on the mounting means of the airproof / dustproof box; and a wiring device to which the mounting frame is mounted.

The present invention is an airproof / dustproof wiring device.
