Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pole capable of accommodating a power line.

[0002]

2. Description of the Related Art Conventionally, there is a pole in which an electric wire branched from an electric power line buried in the ground is erected in an upper branch box through the inside of the pole and lead-in wiring. In this case, the branch box 51 is attached to the upper side surface of the pole 50 as shown in FIG. In addition, lighting equipment (mainly street lights) 5
2 is installed and other automatic blinkers, signs, decorations, etc. are also installed. The electric wire branched from the electric power line buried in the ground in the pole 50 is led to the branch box 51 and wired in each house.

[0003]

However, since the conventional pole is a method of mounting the branch box on the pole by hugging the branch box, the size of the branch box itself becomes conspicuous as it protrudes from the outer surface of the pole, resulting in an aesthetic appearance. There is a problem of damage.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above problems and to provide a pole which can be easily and surely wired and has a good appearance.

[0005]

In order to solve the above-mentioned problems, the pole according to claim 1 of the present invention is configured such that a branch line from a power line buried in the ground is drawn to the upper part through the inside of the pole body. In the pole, an opening provided on a side surface of the pole body, a lid provided to the opening so as to be openable / closable and to maintain waterproofness in a closed state, and from the inside of the opening and the lower portion of the lid. A lead wire insertion portion into which a lead wire can be inserted is provided, and a wiring space for the branch line and the lead wire is provided inside the pole body facing the opening.

Thus, the opening provided on the side surface of the pole body, the lid provided to the opening so as to be openable and closable and to maintain the waterproof property, and the opening and the lower portion of the lid. It has a drop-in wire insertion part that can insert a drop-in wire from the inside, and a wiring space for branch lines and drop-in wires is provided inside the pole body facing the opening, so wiring can be performed easily and reliably using this wiring space. Therefore, it is not necessary to provide an external branch box. This makes it possible to shorten the construction process, reduce the manufacturing cost, and improve the appearance.

The pole according to claim 2 is the pole according to claim 1, which also serves as a lead-in for the information wiring. In this way, since it also serves as a lead-in for information wiring, it is possible to perform wiring of various line types in consideration of the information society.

According to a third aspect of the present invention, in the pole according to the first aspect, the lid body is substantially flush with the side surface of the pole body in the closed state. In this way, since the lid body is substantially flush with the side surface of the pole body in the closed state, the pole body and the lid body have a feeling of unity and a good aesthetic appearance can be obtained.

According to a fourth aspect of the invention, in the pole according to the first aspect, the service wire insertion portion is formed continuously with the lower end of the opening and has an inclined surface so that the upper portion is located inside the pole body. It has an electric wire guide. In this way, the drop wire insertion part is formed continuously at the lower end of the opening and has the wire guide part having the inclined surface so that the upper part is located inside the pole body, so that the drop wire can be smoothly inserted in the pole body. You can call in. In addition, it is possible to insert the drop wire in a state close to the pole axis direction, and there is no risk of damaging the drop wire at the edge of the member. Moreover, since the inside of the pole body is not exposed at the drop wire insertion portion, it is possible to prevent rainwater from entering and protect the inside of the pole.

According to a fifth aspect of the invention, in the pole according to the first aspect, a lighting attachment portion is provided on a side surface of the pole body. In this way, since the lighting attachment portion is provided on the side surface of the pole body, it is not necessary to newly install a support by sharing the pole for lighting, and a good landscape can be created.

According to a sixth aspect of the present invention, in the pole according to the first aspect, the lid is fixed by a hinge.
In this way, since the lid is fixed by the hinge,
It is possible to secure safety during construction and save construction work.
