[0002]
[Prior art]
A railway vehicle is equipped with a myriad of wiring harnesses (covered wires) that are long in the longitudinal direction, and wiring systems (wiring harnesses, repeaters, switchboards, etc., are used to supply power to railway vehicles, control signal transmission, detection signal transmission, etc. The wiring harness is configured in such a manner that a large number of wiring harnesses are cut in advance one by one at a predetermined length, and a predetermined connector is connected to both ends thereof. The parts requiring bundling and protection are covered with pipes, rubber tubes, and the like, and the bundle of wiring harnesses is fixed to a vehicle floor, a roof, or the like for each bundle at a predetermined interval with an appropriate fixing bracket.
Also, as shown in FIG. 1, for example, a large number of wirings without relay between various devices 1a, 1b,..., Such as a motor controller, a stationary power supply device, a brake control device, a door opening / closing controller, etc. Since the wiring is performed using the harness, the wiring harnesses 3a, 3b, 3c,... From the devices located in various directions are connected to one device in an octopus foot wiring shape. For this reason, it is not possible to put together a single harness for each device, and the wiring harness is often congested.
Further, since it is not possible to put together one wiring harness in advance for each device, an additional connection is made to the connector at the site.
In the conventional railway vehicle wiring system as described above, a lot of trouble is required for the preliminary work for wiring, and a lot of work and time are required for laying on the vehicle main body and connecting individual wiring harnesses to the equipment. Cost. For this reason, the wiring operation cost increases.

It is an object of the present invention to devise a configuration of a wiring system so that a wiring harness can be unitized as much as possible.
[0004]
[Measures taken to solve the problem]
Means taken to solve the above-mentioned problems are configured on the premise of a wiring system of a railway vehicle wired under the floor, ceiling, and side walls of the railway vehicle, and are configured by the following requirements (a) to (d). .

[Action]
The work of connecting individual devices and repeaters with a number of wiring harnesses is an on-site work, but the wiring harness between the devices and the repeaters is short and easy to handle. This wiring work is simple and easy because it is a connection work between devices.
Preliminary work such as cutting and connection of a connector for the relatively short wiring harness is extremely simple and easy as compared with preliminary work for the long wiring harness.
In addition, several main repeaters are interposed in a wiring section where a plurality of wiring harnesses are grouped into a main multi-core cable, and the connectors of the individual cores formed as the main multi-core cables are connected to the main repeater connector. , The trunk multi-core cables of the main repeater are connected to each other by a number of core wires. As a result, remote devices are connected via trunk multi-core cable branch multi-core cables, sub multi-core cables, sub main repeaters, and short individual wiring harnesses. Since the lengths of all the core wires of the respective multi-core cables are equal, each multi-core cable is cut at a predetermined length, and connectors are connected to both ends thereof, so that a main multi-core cable for wiring is formed. Can be easily prepared.
In the wiring work, a predetermined repeater is mounted at a predetermined position, each repeater is connected with a predetermined multi-core cable, and the repeater and each device are connected with a required wiring harness.
Thereby, each device is connected to each other by the individual wiring harness, the repeater, and the multi-core cable.
Since it is easy and easy to fix the multi-core cable to the vehicle body at predetermined intervals, the wiring work is performed simply.
Also, since the branch multi-core cable branched from the trunk multi-core cable of the main repeater is branched into a sub multi-core cable, the main repeater and the sub repeater are connected by a sub multi-core cable, and Various devices can be connected by individual wiring harnesses.
As a result, the number of core wires of the long multi-core cable can be reduced, so that the diameter and weight of the multi-core cable can be reduced and the laying operation can be facilitated.
In addition, since the trunk multicore cable is branched into a number of submulticore cables via branch / branch multicore cables, by connecting the ends of the individual submulticore cables to the corresponding sub repeaters. Since one main repeater and a number of sub repeaters can be connected with one sub multi-core cable, the required number of multi-core cables can be reduced. Therefore, the work of laying the multi-core cable can be further simplified.
