Description

[Detailed Description of the Invention] The present invention relates to a packing that is attached to a separator of a branch connection line that branches from a feeder line and supplies power to an overhead contact line.

(Prior art) A branch connection line that supplies power to the overhead contact line from a feeder wire placed above the overhead contact line is connected to the overhead contact line while being held at a predetermined distance from the overhead contact line by a separator. The separator may be tilted by vibrations of the overhead contact line, etc., and if the separator is tilted, the predetermined distance between the branch connection line and the suspension line cannot be maintained, so it is not necessarily safe.

As shown in the fourth diagram, this separator has a cylindrical split body S1 formed by combining two splittable semi-cylindrical parts and a mounting hole S2, and has an attachment hole S2.
Attach the separator S by hooking the mounting hole S2 to the hanging wire M that hangs the hanger H that is hanging the separator S.
A branch connection line F1 that branches from the feeder line F above the suspension line M and is connected to the overhead contact line T to supply power is passed through the bifurcated cylinder S1 of the separator S and held at a predetermined distance from the suspension line M. It is something. When such a separator S is subjected to vibrations from the overhead contact line, it tilts downward as shown by the dotted line, and as a result, the predetermined distance between the branch connection line F1 and the suspension line M is not maintained, which is dangerous. Ta. However, if the separator S is fixed to the hanging wire M in order to prevent this tilting, it becomes difficult to attach and detach the separator S, and therefore, conventionally, there has been no effective means for preventing the separator from tilting.

(Present invention) In view of the above-mentioned points, the present invention provides packing for a feeder branch line separator, which is attached to the separator of a branch connection line of a feeder line and maintains the branch connection lines at a predetermined interval. The configuration will be explained below with reference to illustrated embodiments.

FIG. 1 shows a front view of one embodiment of the present invention in partial cross section, FIG. 2 is a bottom view thereof, and FIG. 3 is an A of FIG. 1.
- It shows a part of the front as seen in the A-line direction.

In the figure, reference numeral 10 denotes a hollow cylinder made of rubber such as synthetic rubber, the hollow part of the cylinder is a hollow part 1 through which a branch connection line of a feeder line is inserted, and the cylinder wall has a cut part 2 in the axial direction. will be established. The cylinder body 1 is
The outer circumferential surface of the upper half is formed into a tapered circumferential surface 5 whose diameter gradually decreases from the flange edge 3 at the upper end to the middle part 4, and the outer diameter of the lower half is uniform from the middle part 4 to the lower end. It is formed into a small diameter cylindrical portion 6. Also,
A plurality of protrusions 7 extending downward from the intermediate portion 4 are provided on the outer circumferential surface of the small diameter cylindrical portion 6, and the ridgeline of each protrusion 7 is aligned with the tapered circumferential surface 5 as shown in the third figure.
It is formed into a tapered ridge line 8 that continues. Reference numeral 9 denotes a portion of the small diameter cylindrical portion 6 extending downward from the end of each protrusion 7.

The packing for a feeder branch line separator of the present invention is constructed as described above, and is installed in the bisected cylinder S1 of the separator S through which the branch connection line F1 of the feeder line is inserted, as shown in the fourth diagram. . This attachment is performed by opening the cut portion 2 of the rubber hollow cylinder 10 and inserting the branch connecting wire F1 into the hollow portion 1, and then opening the bifurcated cylinder S1 of the separator S and inserting the branch connection wire F1 into the hollow portion 1 of the rubber hollow cylinder 10. The rubber hollow cylinder 10 through which the connecting wire F1 is inserted is inserted, and the two-split cylinder S1 is closed again into a cylindrical shape, and the rubber hollow cylinder 10 is inserted into the two-split cylinder of the separator S as shown by the dotted line in FIG. It is installed inside the body S1.

As a result, the cut portion 2 of the rubber hollow cylinder body 10 is compressed and closed by the inner peripheral surface of the two-split cylinder body S1 of the separator S, so that the branch connection inserted into the hollow part 1 of the rubber hollow cylinder body 10 is closed. The line F1 is also compressed and held by the inner peripheral surface of the rubber cylinder 10, so that the separator S is prevented from tilting downward.

(Effect of the invention) As described above, in the present invention, the hollow cylindrical body 10 made of rubber is provided with the cut portion 2 that communicates with the hollow portion 1, so that the branch connection line F1 of the feeder line can be easily connected to the hollow portion 1. Not only can the branch connection line F1 be fitted into the separator S, but also the branch connection line F1 can be elastically compressed and held by the cylindrical wall of the rubber cylinder 10 when attached to the separator S. Further, the outer circumferential surface of the upper half of the hollow cylindrical body 10 is formed into a tapered circumferential surface 5 that tapers downward, and the lower half is formed into a small diameter cylindrical portion 6, which has a tapered ridge line 8 on the outer circumferential surface. Since a plurality of protrusions 7 are provided, when this rubber hollow cylinder body 10 is installed in the two-split cylinder body S1 of the separator S, the tapered peripheral surface 5 in the upper half and the plurality of protrusions in the lower half are separated. Each tapered ridgeline 8 of 7 is divided into two cylinders S
It can be elastically pressed against the inner surface of 1 and fixed. Therefore, since the separator S can be elastically fixed to the branch connection line F1 via the rubber hollow cylinder 10, the separator S does not tilt downward as in the conventional case, and the branch connection This allows the lines F1 to be maintained at predetermined intervals. Moreover, since the flange 3 is provided at the upper end of the hollow cylindrical body 10, the hollow cylindrical body 10 will not fall down from the separator S, making it safe.
