[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof wiring box which is internally connected when electric wiring is performed indoors and outdoors.

[0002]

2. Description of the Related Art Conventionally, in a wiring box made of a synthetic resin of this kind, as shown in FIG. 6, a larger cover 101 is attached to a box body 100, or a cover plate having the same size as the box body is attached to a rubber plate. The box body 100 is attached to the wall A or the like with screws 10
2, and a wiring tube is appropriately inserted into the peripheral wall or the bottom wall of the box body 100 to connect the wiring inside.

[0003]

In the former conventional wiring box, the former has a large lid to cover the box body. Therefore, when the wiring box is mounted on a wall, the wiring box is inclined as shown in FIG. Is also bad. In addition, when connecting the internal wiring after installing the wiring box on the wall, it is inconvenient because the lid is difficult to detach and attach to the wall because the lid is held on the wall and the rubber when attaching the latter lid plate to the box body When the four corners of the packing are tightened, a force that bulges upwards acts on the center of the packing, and the center of the packing is deformed in a curved shape and rainwater invades, causing a problem of electric leakage. .

In this invention, the lid is fitted within the outer shape of the waterproof frame attached to the box body, the lid and the outer peripheral surface of the box body are aligned, and the lid is easily attached to the wall surface. It is another object of the present invention to provide a waterproof type wiring box in which waterproofness is improved by interposing a waterproof frame.

[0005]

In order to achieve the above object, the waterproof type wiring box of the present invention is provided around the opening 2.
A box provided with a groove 7 for fitting the ridge 8 of the waterproof frame 3
The body 1 has the same outer diameter as the box body 1 and
An eaves-shaped waterproof ridge 5 is provided on the upper peripheral edge of the frame
Only the thickness L of the peripheral wall of the lid 4 is provided on the lower peripheral edge by the waterproof ridge 5.
Forming a receiving portion 6 of a lid protruding outward, and projecting around the lower surface.
The waterproof frame 3 formed with the ridges 8 and the box body 1
The height H of the peripheral wall is the same size as the diameter, and the waterproof ridge of the waterproof frame 3 is used.
Fit the lid 4 which is higher than the height of 5 with the outer circumference of the lid 4 aligned.
It can be attached .

At four corners inside the box body 1, mounting cylinders and the like are provided.
Attachment portions 10 are provided at four corners of the waterproof frame 3 so as to fit the attachment portions.
A mounting hole 11 is provided to fit
A screw hole 12 is provided, and the lid 4 is aligned with a screw hole of the waterproof frame.
Mounting holes 15 on each
It is a thing .

[0007]

According to the structure of the present invention, the ridge 8 on the lower surface of the waterproof frame 3 is fitted into the groove 7 of the opening 2 of the box body 1, and the mounting hole 11 and the mounting cylinder 10 are screwed or the like. Then, the cover 4 is put on the outer side of the ridge of the waterproof frame 3 so that the receiving portion 6
Abuts on the mounting hole 15 and the screw hole 12 with screws or the like,
This wiring box can be tightly joined to the wall A and attached with screws or the like. The method of wiring to the box body is similar to a conventional wiring box, in which a wiring tube is inserted into a peripheral wall or a bottom wall and wiring is connected inside.

[0008]

1 to 5, reference numeral 1 denotes an opening 2 at the top.
Mounting box 10 having a concave groove 7 in the upper peripheral wall thereof and having screw holes 9 in four internal corners.
Is provided.

3 is the same size as the outer diameter of the box body 1.
A quadrangular waterproof frame having an opening formed therein is integrally formed with an eaves-shaped waterproof ridge 5 on its upper surface, and projects outwardly from the waterproof ridge 5 on the lower peripheral edge of the waterproof ridge 5. A receiving portion 6 of the lid 4 to be put on the outer periphery is provided, and a ridge 8 which fits into the concave groove 7 of the box body 1 is formed around the lower surface thereof. The width L of the receiving portion 6 protruding from the waterproof ridge 5 is set to a width corresponding to the thickness of the lid 4, and the outer surface of the lid matches the outer surface of the waterproof frame when the lid 4 is put on the waterproof frame 3.

At the four corners of the waterproof frame 3, screws of the mounting tube 10 are provided.
A mounting hole 11 is provided so as to match the hole 9, a screw hole 12 is provided in the middle of two sides of the mounting hole 11, the waterproof frame 3 is fitted to the box body 1, and the mounting cylinder 10 is screwed through the mounting hole 11 with a screw 13. The cover 4 is fixed to the screw hole 12 of the waterproof frame 3 with the screw 14. In the embodiment, the waterproof frame and the box body are fitted and screwed together, but may be fixed with an adhesive.

Reference numeral 4 denotes the outer diameters of the box body 1 and the waterproof frame 3
With a rectangular lid having the same size , the depth H of the peripheral wall is made slightly deeper than the height of the waterproof ridge 5 of the waterproof frame 3. 15 is
It is a mounting hole provided at a position corresponding to the screw hole 12 of the waterproof frame 3 . The materials of the box body 1, the waterproof frame 3, and the lid 4 are made of synthetic resin.

With the above-described structure, the method of assembling the wiring box will be described. As shown in FIG. 1, a ridge 8 on the lower surface of the waterproof frame 3 is fitted into the concave groove 7 of the opening 2 of the box body 1. and mounting holes in the four corners 11, the screw 13 fastening fixed to screw holes 9 of the mounting cylinder 10, proof of the waterproof frame 3
Cover the outer wall of the water ridge 5 with the lid 4 and put the peripheral wall on the receiving portion 6.
Contact the box body, the waterproof frame and the lid
A screw 14 is tightened and fixed in the mounting hole 15 of the lid 4 and the screw hole 12 of the frame 3. Box body and waterproof frame screw 13,
By displacing the screws 14 on the waterproof frame and lid, rainwater
Entry is prevented .

The wiring box thus assembled is fixed to the wall A in close contact with the screw 16 as shown in FIG. Wiring pipes 17 are inserted into the peripheral wall and the bottom wall of the wiring box, and a wiring cord 18 is inserted thereinto, thereby connecting the wiring inside.

[0014]

[Effect of the invention] According to this invention, it matches the box body.
Allowed by receiving the peripheral wall of the lid into the inside contour of the waterproof frame to be fitted deposited
Fitting can attach met with the outer lid, waterproof frame, so to match the outer periphery of the box body can attached to Rukoto,
The wiring box can be screwed securely by closely contacting the wall,
In addition, when connecting the internal wiring after the attachment, the lid is easily detachable, which is convenient for connection work.

Since a waterproof frame provided with an eave-shaped ridge is interposed between the box body and the lid , even if rainwater enters from between the box and the lid, the eaves-shaped ridge completely prevents the intrusion into the inside. And there is no danger of electric leakage. Furthermore, since the groove and the ridge are mutually fitted between the box body and the waterproof frame and are attached by screws or the like, it is possible to completely prevent rainwater from entering.

The positions of the screws of the box body and the waterproof frame and
The screw of the water frame and the lid is shifted and screwed
Thus, rainwater can be prevented from entering .
