Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lead-in pole device for leading electric wires such as power lines and telephone lines into houses and the like.

Generally, electric wires are brought into a house in the following manner. That is, as shown in FIG. 1, a retaining metal fitting 2 is attached to the upper part of a hollow residential service pole 1, and a drop-in wire 4 of an overhead electric wire 3 is connected from the wire entry port 5 of the service pole 1 to the inside of the service pole 1. Then, this electric wire 4 is pulled out of the lead-in pole 1 again from the outlet 5- provided in the middle part of the lead-in pole 1, and then pulled into the box 6 through the bottom opening of the box 6 attached to the lead-in pole 1. , connect to the built-in watt hour meter. Then, the electric wire 7 connected to the watt hour meter is pulled out from the bottom opening of the box 6 and inserted into the lead-in port 8 of the lead-in column 1.
This is done by reaching the inside of the house 9 through the inside of the lead-in column 1 and underground. However, in this case, the 'vL line 4 drawn into the lead-in column 1
The electric wires 4 and 7 are first pulled out to the outside and then drawn into the box 6, and the electric wires 7 from the box 6 are similarly pulled out and then placed inside the lead-in column 1, which results in insufficient protection of the electric wires 4 and 7. The appearance was bad, and there was a problem in that the wires 4 and 7 had to be wired (approximately 1 to 2 m) in length as they were drawn out.

This invention was made in view of the above circumstances, and has the following features:
A wire lead-in pole having a wire lead-in port in the middle part and an opening in the middle part, and a box having a built-in electric meter and attached to the wire lead-in pole with its own 1& direction opening aligned with the opening of the wire lead-in pole. and a waterproof packing that waterproofs the opening of the electric wire lead-in pole and the opening of the box in a communicating state, and the electric wire installed in the electric wire lead-in pillar is drawn into the box through the open state of communication, and the electrical meter number is The gist of the present invention is a lead-in pole device characterized in that the wires of the electric meter can be connected and placed inside the lead-in pole through the communicating opening.

In other words, this lead-in pole device can lead the wires in from the lead-in pole or box without taking them out, so the wires can be completely protected, the appearance can be improved, and the wire can be saved. become.

Next, the present invention will be explained based on examples.

FIG. 2 is a block diagram of an embodiment of the present invention.

In the figure, 10 is a hollow 11L wire lead-in column, which has a lead-in port 11 formed in the L portion and an opening 12 formed in the middle portion. - 13 is a box, which is housed in the retractable column 10 using a mounting bracket 16 with an opening 15 provided in its back plate 14 aligned with the opening 12 of the retractable column 10; 1
Reference numeral 7 designates a watt-hour meter housed in the box 13, which is fixed to the back plate 14 of the box 13 via a meter mounting wooden plate 18. The opening 12 of the lead-in column 10 is formed at a position where the top plate 13a of the box 13 is located 1.5 degrees from the ground.
It is set to be 8 to 2.0 m. 19 is a cap, 20 is an overhead electric wire for lead-in, and 21 is an electric wire (cable)
, 22 are electric wires 7, 2 connected to the meter 17
3 is a waterproof gasket, which waterproofs the opening 12 of the retractable column 10 and the box 13 by communicating with the opening 6i4015. That is, as shown in FIG. 3, this waterproof gasket 23 has a vertically elongated cylindrical shape, with the center part serving as the brim part 24, the upper end part being the retractable column side bushing part 251, and the lower end part being the box part. The box-side bushing part 26 is fitted into the opening 12 of the drawing-in post 10 and the box-side bushing part 26 into the opening 15 of the box 13 to be installed. The above-mentioned section 24 is the lead-in column 10 box 13.
The thickness is set to be larger than the gap between the retractable columns 10° box 13 that is created when the retractable column 10 is installed, and the end face 25 m of the retractable side of the collar portion 24 is formed into a curved shape along the outer periphery of the retractable column 10. An end surface 27 on the box side is formed into a planar shape along the back plate 14 of the box 13. When the waterproof gasket 23a is installed, the end face 25a on the lead-in column side is as shown in FIG.
The outer circumferential surface of 0 is pressed and the end surface 27 on the box side
is in pressure contact with the back plates 1 and 4 of the box 13, and the retracting column 1.0
and the opening 12.15 of the box 13 is waterproofed. j
In Figure 84, 18 is the wooden board 1 for meter installation.28 is the

The box 13 is attached to the lead-in pillar 10 by the lead-in pillar 1.
Fit the retraction column side bushing part 25 of the waterproof packing 23 into the opening 12 of the waterproof packing (5), then fit the box side bushing part 26 of the waterproof packing 23 into the opening 15 of the box 13, and in that state. This is done while pressing the box 13 in the direction of the retracting column 10. As a result, the d portion 24 of the waterproof gasket 23 is compressed by the back plate 14 of the box 13 and the outer periphery of the retractable column 10, thereby achieving waterproofing of the opening 12.15 as described above.

Since this retractable column device is configured as described above,
The drawing of electric f1421 to the lead-in pillar 10 is the same as before, but the drawing of tl1M21 from the lead-in pillar 10 is as follows.
The electric wire 22 is led from the opening 12.15 of the lead-in column 10 and the box 13, and the electric wire 22 is also drawn from the box 13 to the lead-in column 10 from the opening 12°15 of the box 13, and the electric wire 21.22
does not go outside.

Therefore, the electric wires 21, 22. Complete protection and a clean appearance. Moreover, since extra wires are no longer needed, it is possible to save on wires.

As described above, the lead-in pole device of the present invention allows the wires to be pulled in without taking them out from the lead-in pole or box6), so the wires are completely protected and the appearance is improved. savings can also be achieved.
