[Means for Solving the Problems] In order to achieve the above-mentioned object, the trolley wire separator according to the present invention is provided with a first trolley wire suspended from a first messenger wire.
Wire between the first trolley wire and the second trolley wire, which is erected between the first hanger and the second hanger that is hung on the second hanger line, and which is held between the first hanger and the second hanger by a predetermined distance. In the separator for use, at both axial ends of the rod-shaped separator body, a slit extending to a midway portion in the axial direction, and a part of the slit penetrates in the midway portion in a direction intersecting with the slit to communicate with the slit. And an axially extending through-hole and a lateral groove formed by cutting out two diagonally opposite two pieces of the connecting pieces at the four corners formed in the communicating portion are symmetrically arranged in the axial direction. The feature is that it is provided.

[Operation] In the construction of the separator, first, the hangers of the hangers holding the trolley wires respectively are inserted into the slits of the engaging portions provided at both ends of the separator body, and then the separator body is rotated 90 degrees. As a result, each hanger is inserted into the through hole via the lateral groove. Since the through hole is formed in the axially intermediate portion of the separator body and both ends thereof are closed, the hanger does not separate from the through hole due to the axial movement, and the hanger in the engaging portion does not come off. The engagement state can be ensured, and thus the two trolley wires can always be held at a predetermined interval.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

1 to 7 are views showing an embodiment of the present invention.

First, the configuration will be described. In the figure, reference numeral 12 is a separator body, and the separator body 12 has a rod shape with a quadrangular cross section, and the length of the separator body 12 in the axial direction A is stretched in parallel with each other. It is set to a predetermined length for maintaining a predetermined distance between the trolley wires 13, 13. At both ends of the separator body 12, the engaging portions 1 that are symmetrical in the axial direction are provided.
4 and 14 are formed respectively.

The engaging portion 14 is composed of a slit 15, a through hole 16 and a lateral groove 17, and one end of the slit 15 opens to the end face 18 and the other end extends to a midway portion of the axial direction A. The through hole 16 extends in the axial direction in a state in which the through hole 16 penetrates inside the slit 15 which is the midway portion in a direction intersecting the slit 15 at a right angle and partially communicates with the slit 15.
Four connecting pieces 18, 19, 20, 21 extending in the axial direction are formed at the four corners of the portion communicating with.

Of the four connecting pieces 18 to 21, two connecting pieces 18 and 20 facing each other in the diagonal direction are formed with a lateral groove 17 extending in the width direction and notching the connecting piece 18, 20. The shaft member inserted in the slit 15 can be rotated and displaced by 90 degrees.

Generally, as the material of the separator body 12, a synthetic resin material having an insulating property is suitable, but other various materials such as wood and ceramics may be applied. it can.

Next, the operation will be described.

FIG. 7 is a diagram showing a usage state of the separator according to the present embodiment. In FIG. 7, 23 is a hanger ear in which the trolley wire 13 is sandwiched by ear pieces 25 provided at the lower end of the hanger 24. The catenary wire 27 is inserted into the suspension ring 26 provided on the upper end of the two, so that the two catenary wires 27 are used to connect the two trolley wires 1 through the plurality of hangers 23.
3 are individually supported.

The erection of the separator according to the present embodiment can be performed as follows.

First, each hanger 2 of the two facing hangers 23 hung down on the two catenary wires 27 stretched in parallel.

The hanger 24 is made to face the lateral groove 17 provided in the two connecting pieces 18 and 20.

Next, the hanger 24 is inserted into the through hole 16 via the lateral groove 17 by rotating the separator body 12 by 90 degrees. This completes the installation of this separator.

In this case, since the through hole 16 is bored in the middle part of the separator body 12 and both ends thereof are closed, the hanger 24 moves axially only within the length of the through hole 16 and the distance beyond that. Can't move. Further, the lateral groove 17 is set in one diagonal direction, and the movement of the hanger 24 in the width direction of the separator body 12 is restricted by the two connecting pieces 19 and 21 facing each other in the diagonal direction. 24 does not come out of the through hole 16.

As a result, the engaged state of the hanger 24 in each engaging portion 14 is secured, so that the distance between the two hanger ears 23 that are installed opposite to each other is maintained at a predetermined distance. Therefore, the space between the two trolley wires 13 supported by the plurality of hangers 23 can be maintained at a predetermined distance between the engaging portions 14. Therefore, it is possible to prevent the two trolley wires 13 from coming into contact with each other, and it is possible to prevent both trolley wires 13 from coming too close to each other and causing an influence of electromagnetic action due to a current flowing in the trolley wires 13. it can.

In the above embodiment, an example in which the cross-sectional shape of the separator body 12 is a quadrangle has been described, but the present invention is not limited to this, and for example, a hexagon, an octagon, an ellipse, etc. Any shape may be used as long as the separator body 12 is less likely to be rotationally displaced by vibration or the like.

[Advantages of the Invention] As described above, according to the present invention, since the engaging portion including the slit, the through hole, and the lateral groove is provided at both ends of the separator body, the separator for the trolley wire is formed only by the separator body. Can be configured. Therefore, a trolley wire separator that is inexpensive and highly practical can be provided without requiring a large number of constituent parts as in the past, and yet the separator itself has a simple structure and can be easily manufactured. can do. Further, since the erection work can be performed only by operating the separator main body, the erection work can be performed easily and quickly, the work efficiency is excellent, and there is an effect that it is possible to provide a highly safe trolley wire separator. .
