る。[Prior Art] Conventionally, underground power distribution lines have been widely used to maintain the aesthetic appearance of cities. These underground cables are usually underground when they rise above the ground.
The area between 15cm and 2.5m above the ground is housed in a protective tube to prevent damage. A protective tube is a hollow cylindrical metal tube. However, this creates a wide gap between the protection pipe and the underground cable housed in the protection pipe, which allows foreign objects such as stones to enter through this gap, and moisture such as rain to flow in between the protection pipe and the underground cable. There is a risk of damaging both the cable and the underground cable, which in turn could lead to deterioration of the insulation of the underground cable, which led to the proposal of an underground cable riser protection tube cap. Figure 1 A is a perspective view of a conventional underground cable rising protection pipe cap, Figure B is a sectional view AA′, Figure C is a bottom view,
Figure A shows this underground cable rising protection pipe cap 1.
1 is a perspective view showing the protective tube 16 being used, and FIG. In FIG. 1, reference numeral 11 indicates an underground cable rising protection tube cap, 12 indicates its pull-out portion, and 13 indicates its insertion portion. A notch B is formed in the drawer part 12 and the insertion part 13, and a cutting mark 14 is provided in the drawer part 12 according to the diameter of the underground cable to be pulled out.
Since a clamp protrusion 15 is formed, it can also be attached to an existing protection pipe 16 as shown in FIG. That is, in the case of a normal distribution line, the underground cable 17 is composed of three cables of the same diameter, and depending on the diameter of the underground cable 17, an arbitrary mark in the cutting mark 14 of the pull-out part 12 is used to cut the cable. Cut out the pull-out part 12, push out the notch B, and fit the underground cable 17 into the underground cable rising protection tube cap 11 so as to wrap it there.After that, fit the insertion part 13 into the protection tube 16, and press the clamp protrusion 15. Align the parts at symmetrical positions with respect to the notch B, and press the clamp button 18 into the aligned 2
It is inserted into the coupling holes of the two clamp protrusions 15.

Figure 2 shows a sectional view of K and K', and Figure 2 shows a sectional view of LL' in Figure 3, respectively. In the figure, the code 2
1 to 25 and 28 are the symbols 11 to 28 shown in FIG.
15 and 18 represent the same components. The underground cable rising protection pipe cap 21 according to this embodiment has a feature in the internal structure of the drawer part 22, as shown in Figures 1 and 2. That is,
As shown in the LL′ cross-sectional view of Figure 2, the thickness of the drawer portion 22 is increased by a protrusion Y that protrudes inward in the circumferential direction.
The outer circumferential shape when three circles with the same radius are in close contact with each other,
A so-called trefoil pattern 30 is formed, and a pull-out hole 40 whose diameter decreases in the pull-out direction is formed in accordance with the trefoil pattern 30. Furthermore, the pull-out hole 40 is formed continuously in the axial direction of the pull-out portion 22. Furthermore, cutting marks 2 are provided when cutting the pull-out portion 22 according to the radius of the underground cable.
4 and the arrangement of this trefoil pattern 30 are matched. For example, if you cut at the top of the drawer part 22 which is marked 60 mm 2 among the cutting marks 24, the cross section will be 60 mm 2.
A trefoil pattern 30A, which is a cross-sectional pattern obtained when three mm 2 underground cables are brought into close contact with each other, appears on the top surface of the drawer portion 22. Therefore,
If you cut it with a cross section of 150 mm 2 , you will get a trefoil pattern 30B.
If you cut it at 250mm 2 , you will get a trefoil pattern 30C with a cross section of 400mm 2
If it is cut at , a trefoil pattern 30D will appear on the top surface of the drawer portion 22.

As shown in FIG. Since the underground cable 27 is smoothly cut and inserted from F, the underground cable rising protection pipe cap 21 does not shift from side to side, and the clamp protrusions 25 can be aligned. In addition, since the thin valley part G of the drawer part 22 and the thick part H having the three protrusions Y described above face each other, when opening the notch F,
A strong force acts on the thick part H to maintain the shape, and the drawer part 22 into which the underground cable 27 is inserted
This makes it easier to close.

Figure A is a perspective view thereof, and Figure B is a sectional view thereof. The figure is 150mm 2 as an example.
The figure shows a state in which it is inserted into a protection pipe 26 that protects a single-core three-strand underground cable 27 having a cross section of .
As shown in Figure B, in such a case, if the drawer part 22 is cut using the cutting mark for 150mm 2 , the cutout will be 150mm 2.
A trefoil pattern 30B appears on the cross section, and while the three single-core three-strand underground cables 27 are brought into close contact with each other,

When the drawer portion 22 is cut based on the appropriate cutting mark 24 according to the cross-sectional area of 7, a cross-sectional shape is obtained that allows the single-core three-wire underground cables 27 to be brought into close contact with each other and to allow them to be inserted without any problems. , a so-called trefoil pattern 30 appears in the cross section. Further, even if the single-core three-strand underground cable 27 is cut at a location other than the cutting mark 24 of the pull-out portion 22 depending on the cross-sectional area, the trefoil pattern 30 will appear in the cross section. Therefore, using this underground cable rising protection tube cap 21, single core 3
By inserting the double-strand underground cable 27, the rising portion of the single-core three-strand underground cable 27 can be completely protected without creating any gaps as shown in FIG. 4B. Furthermore, since the diameter of the pull-out hole 40 corresponding to the trilobal pattern 30 is reduced in the pull-out direction, the cut point of the pull-out portion 22, for example, the cut point of 60 mm 2 in FIG.
The diameter of the pull-out hole 40 is larger at the cut point of 150 mm 2 . Therefore, even if the underground cable 27 is twisted, the underground cable 2
There is a gap between 7 and the trefoil pattern 30, and even if the underground cable 27 is twisted, there is no gap only at the cut point, so it is possible to ensure tight contact and easy insertion. .
