Abstract

PROBLEM TO BE SOLVED: To simplify the laying work of an insulated trolley line and a line for transmitting a communication signal showing information by forming an insulating cover for a trolley conductor and the sheathing of a communication cable integrally by use of a common insulating sheath. SOLUTION: A trolley conductor 1, a communication cable 3 and a messenger wire 4 are integrated together by a common insulating sheath 2. In the insulating sheath 2, a pair of leg-like parts is formed in the part for covering the trolley conductor 1 to form an opening, and the current collected surface 5 of the trolley conductor is exposed to this opening, so that the insulating sheath 2 functions as the insulating cover of the insulated trolley line. The insulating sheath 2 functions as a sheath in the part for covering the communication cable 3. According to this structure consisting of both the trolley line path and the communication line path, the laying work can be simplified.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulated trolley wire for supplying power and information signals to mobile equipment, and more particularly to the provision of such an insulated trolley wire combined with a communication cable.

[0002]

2. Description of the Related Art Insulated trolley wires are used to transmit electric signals representing power and information to mobile electric equipment. Signals such as video, audio, and data are transmitted between the mobile electric equipment and ground equipment. When performing communication, a communication line such as a leaky coaxial cable, an inductive radio cable, or an optical fiber cable is used separately from the insulated trolley wire.

[0003]

According to the prior art described above, since the insulated trolley wire and the communication cable are separately laid, different mounting members are required for each of the insulated trolley wire and the communication cable. Since separate installation work is required, the installation work is complicated and the cost is increased.

Therefore, the problems to be solved by the present invention (objects)
An object of the present invention is to provide a communication cable composite insulated trolley wire which can simplify the installation work of an insulated trolley wire and a line for transmitting a communication signal representing information and can realize a low cost.

[0005]

According to the present invention, there is provided a communication cable composite insulated trolley wire provided by arranging a communication cable in parallel with a trolley conductor covered with an insulating cover while leaving a current collecting surface, and an insulating cover for the trolley conductor. And the outer jacket of the communication cable are integrally formed with a common insulating sheath.

The communication cable is preferably selected from a tightly coupled coaxial cable, an inductive radio cable, and an optical fiber cable.

[0007] Along with the trolley conductor and the communication cable,
Messenger wires may be incorporated into a common insulating sheath.

FIG. 1 shows a first embodiment of a communication cable composite insulated trolley wire according to the present invention, wherein 1 is a trolley conductor, 2 is an insulating sheath (insulating cover), 3 is a communication cable, and 4 is a communication cable. The messenger wire cables 5 and 5 indicate the current collecting surface of the trolley conductor 1.

In the communication cable composite insulated trolley wire of the first embodiment, three trolley conductors 1 each having a substantially rectangular cross section are arranged in parallel, and the communication cables 3 are arranged side by side on one side in the parallel direction. Messenger wires 4 are arranged side by side on both sides, and these trolley conductors 1 and communication cables 3
And a messenger wire 4 integrated with a common insulating sheath 2.

The insulating sheath 2 is formed with a pair of legs formed at portions where the trolley conductor 1 is covered, and an opening is provided. In the opening, a current collecting surface 5 of the trolley conductor is exposed to form an insulating trolley wire. It functions as an insulating cover. The insulating sheath 2 functions as a jacket at a portion where the communication cable 3 is covered.

The communication cable composite insulated trolley wire having the above structure is laid in a straight line by applying tension to the messenger wires 4 on both sides, and the trolley conductor 1 is connected to a power supply cable or the like at a connection terminal. Further, the communication cable is connected to a communication station or the like. Then, the current collection (collector brush, etc.) of the current collector attached to the mobile electric device is caused to travel together with the mobile electric device while being in contact with the current collecting surface of the trolley conductor, so that power collection to the mobile electric device is performed. To

The communication cable 3 includes a tightly coupled cable, a leaky coaxial cable, an inductive radio cable, an optical fiber cable, and the like, and is used for information transmission between the mobile electric equipment and the ground.

As described above, since the trolley circuit and the communication line coexist, it is not necessary to lay a communication cable separately from the trolley circuit, so that the laying work can be simplified and the cost can be reduced. Can be.

FIG. 2 shows a second embodiment of a communication cable composite insulated trolley wire according to the present invention, wherein 1 is a trolley conductor, 2 is an insulating sheath (insulating cover), 3 is a communication cable, and 5 is a trolley. 4 shows a current collecting surface of a conductor.

In the communication cable composite insulated trolley wire according to the second embodiment, three trolley conductors 1 having a cross section of a letter "C" are arranged in parallel, and the communication cables 3 are arranged side by side on one side in the parallel direction. The trolley conductor 1 and the communication cable are integrated by a common insulating sheath 2.

The insulating sheath 2 has an opening formed by a pair of leg portions at a portion covering the trolley conductor 1, and a current collecting surface 5 of the trolley conductor 1 is exposed in the opening to form an insulating trolley wire. It functions as an insulating cover, and also functions as a cable jacket at a portion where the communication cable 3 is covered.

The communication cable composite insulated trolley wire having the above structure is laid using a hanger or the like along a rail for moving equipment, the trolley conductor is connected to the power supply cable by a connection terminal, and the communication cable is Connect to a communication station or the like. Then, while collecting the current of the current collecting device attached to the mobile electric device and contacting the current collecting surface 5 of the trolley conductor, the mobile electric device is caused to travel, thereby collecting power to the mobile electric device. It is. The communication cable 3 may be used in the same manner as in the first embodiment.

In the communication cable composite insulated trolley wire of this embodiment, the same effects as those of the first embodiment can be obtained.

[0019]

According to the present invention as described above, the communication cable composite insulated trolley wire which can simplify the installation work of the insulated trolley wire and the line for transmitting the communication signal representing information and can realize the cost reduction.
