Fig. 2 is a diagram showing a transmission path of a train information transmission and reception system. As shown in Fig. 1, the information transmitting and receiving device 1 is mounted on each of the vehicles 2〇1 of the train 200, and is connected to each of the information transmitting and receiving devices mounted on the adjacent vehicles 201 and 201 by the transmission path. As shown in Fig. 2, the transmission path u is for connecting the second vehicle inner cable line 21, the first vehicle side connector 21a, the first jumper connector 61, the vehicle jumper cable 6〇, and the second span. The connector 62, the second vehicle-side connector 22a, and the second in-vehicle distribution cable 22 are connected. The information transmission and reception system is via the first in-vehicle distribution cable 21, the first vehicle-side connector 2ia, the second-span jumper 61, the vehicle cross-buckling, the second cross-connect (four) 62, and the second vehicle-side connector pool. The vehicle side connector 22a is placed on the rear side end portion by the stone information. The f-connector 6 is mounted on the vehicle crossover 6Q. The first cross-connector 6 is connected to the first vehicle-side connection 320930 7 1344428 21a, and the other is fitted to the second vehicle-side connector 22a, and the first vehicle is equipped with the cable 21 The vehicle jumper cable 60 and the second vehicle inner wire winding 22 are connected. Figure 3 is a cross-sectional view of the vehicle jumper cable 60 of the embodiment. In the vehicle jumper cable 60, a jumper cable with a plurality of cables is used. The vehicle jumper cable 60 is obtained by coating a plurality of shielded twisted pair wires 80, a plurality of shielded wires 33, and a plurality of unshielded wires 32 bundled with a wire harness sheath (protective cover) 34. By. There are various options for the number of wires, the wire arrangement, and the wire diameter of the vehicle jumper cable. The vehicle jumper cable of the present invention is not limited to the vehicle jumper cable 60 of the embodiment. Figure 4 is a cross-sectional view of an unshielded wire. The unshielded electric wire 32 is a person who covers the electric wire 35 with the cylindrical insulating layer 37. Figure 5 is a cross-sectional view of the shielded wire. The structure of the screen wire 3 3 is configured such that the wire 35 is covered with the cylindrical insulating layer 38, and the insulating layer 38 is covered with a shield layer (shielding layer) 36 which is formed into a cylindrical shape by a copper wire or the like, and is covered with the cylindrical insulating layer 39. Shield layer 36. Figure 6 is a cross-sectional view of the shielded twisted pair wire. The twisted pair electric wire 80 is obtained by twisting two insulated electric wires obtained by coating the electric wires 85 and 85 with the cylindrical insulating layers 87 and 87, and covering the outer periphery of the shield layer 86, and then covering the outer peripheral skin (protective coating) 84. Construction. The jumper cable used in the vehicle jumper cable 60 that directly bridges between vehicles is required to have a high degree of mechanical strength, so that a hard copper wire is provided in the center of the wires 35, 85 in the jumper cable, and Twist the soft copper wire around it and construct 8 320930 1344428 ' into wires 35, 85. Fig. 7 is a cross-sectional view of the shielded twisted pair wire as the second and second in-vehicle distribution cable turns 22, which is configured to be covered with a cylindrical insulating layer 27 on the outer periphery of the electric wires 25 > The two insulated wires of 27 are twisted, and the shield layer 26 is covered around the outer layer, and then covered by the outer peripheral skin (protective cover) 24. In general, shielded cables are less susceptible to external noise. The other side ©' because the train is equipped with various types of high-voltage or high-frequency electric machines, noise is often generated. Therefore, the shielded twisted pair cable 22 shown in Fig. 7 is used as a transmission path in the vehicle. Further, the shielded-back twisted pair 80 is selected from the wires constituting the handle jumper cable 60 as a transport path in the portion between the jumper and the vehicle. Figures 8 through 12 are diagrams schematically showing a general train information transmission and reception system. In the train information transmission and reception system shown in Fig. 8, the second and second vehicle-side connector 21a, 22a have a vehicle body 1 that is grounded to the vehicle 20 via the shield grounding wire 1〇〇. 1. Each of the ground terminals 21b to 22b of 1〇1 and two (complex) signal transmission path terminals 2ic and Me. The first and second in-vehicle distribution cable lines 21 and 22 each have two (multiple) signal transmission path terminals 21C and 22c and one of the information transmission and reception devices 10 of the first and second vehicle-side connectors 21a and 22a. a plurality of connected signal transmission paths (wires) 25, 25; and a shielding layer 26, % grounded to the vehicle body 2 (the body 101, 101 of the Π, 201 and shielding the plurality of signal transmission paths 25, 25). 9 320930 1344428 The vehicle jumper cable 60a includes a twisted pair electric wire 80 that is provided with a ground terminal 21b that is respectively connectable to the first and second vehicle side connectors 21a and 22a at both end portions, 22b and a plurality of signal transmission path terminals 21c, 22c mating the grounding terminals 61b, 62b and a plurality of first and second jumper connectors 61, 62 of the crossover signal transmission path via the terminals 61c, 62c, and having a plurality of crossover signal transmission paths 85, 85 for connecting a plurality of crossover signal transmission path terminals 61c, 62c of the first and second jumper connectors 61, 62 to each other; and a shielding layer 86 for a plurality of strips The cross-signal transmission paths 85, 85 are shielded and connected丨, the second jumper connectors 61, 62", that is, in the train information transmission and reception system shown in Fig. 8, two of the two ends of the shielded twisted pair electric wires 8 of the vehicle jumper cable 60a The shield layer 86 is connected to the grounding terminals 61b and 62b of the second and second jumper connectors 61 and 62, the grounding clamps 21b and 22b of the second and second vehicle-side connectors 21a and 22a, and the shield grounding wire. 1〇〇, 1〇〇, and the vehicle body IQ, 1〇1 is grounded. In the train information transmission and reception system shown in Figure 8, in the railway vehicle where the potential of the vehicle body is not the place, In the train information transmission and reception system shown in Figure 9, only the one side of the twisted pair wire 8 that is shielded by the vehicle auxiliary jumper 60 is one side. The shield layer 86 is grounded to the vehicle body 101 by the jumper ground terminal (4) of the first jumper connection 61, the ground terminal 21b of the first vehicle side connector 21a, and the shield ground line 1〇〇. 320930 10 1344428 ' The first diagram shows the state in which the vehicle jumper cable 60 is connected in a state opposite to the connection state shown in Fig. 9 In this state, the shielding layer 86 is not grounded on the vehicle body 1 〇1 on either side. In the connection state shown in FIG. 10, since the shield layer 86 of the vehicle jumper cable is not grounded, There is less shielding effect on external noise. In the train information transmission and reception system shown in Figure 9, if the direction of the vehicle 2 〇 1 • is changed, the connection state as shown in Fig. 11 will be obtained, Fig. 11 The connection state shown is also the same as the connection state shown in Fig. 10, and the external _ miscellaneous "ITL has less filial piety. In order to secure the grounding state as shown in Fig. 9 to obtain sufficient external noise shielding effect, it is necessary to consider not only the direction of the vehicle jumper cable 6 but also the direction of the vehicle 201 to connect the vehicle 201. In the train information transmission and reception system shown in Fig. 12, the shield layer 86 of the shielded twisted pair electric wire 80 of the vehicle crossover line 60b is not grounded to the vehicle body. The direction of the vehicle jumper cable 60b or the direction of the vehicle 201 is still the same connection state even if the change is made. Therefore, when the train 200 is connected, it is not necessary to consider the direction of the vehicle jumper cable 60b or the vehicle 201, but The point where the sufficient external noise shielding effect is not obtained is the same as the connection state shown in the first and nth views.
