That is, in the train information transmission and reception system shown in Fig. 8, at two ends of the shielded twisted pair wires 80 of the vehicle jumper 60a, the shield layer 86 is connected via the first and second jumpers. The grounding terminals 61b and 62b of the connectors 61 and 62, the grounding electrodes 21b and 22b of the second and second vehicle-side connectors 21a and 22a, and the shield grounding wires 1〇〇 and 1B are in the vehicle body. I. Grounding. In the train information transmission and reception system shown in Fig. 8, in the railway vehicle handle where the potential of the vehicle body is not fixed, there is a doubt that the shield layer (10) flows a large amount of current and is blown. In the train information transmission and reception system shown in Fig. 9, only one side of the twisted pair of wires 8 屏蔽 shielded by the vehicle across the fiber line 60, the shield layer 86, = by the first jumper connector The jumper grounding terminal of 61, the vehicle side = the grounding end of the connector 2la, 21b, and the shield grounding wire 1〇〇 are grounded to the vehicle body. 320930 10 201026537 The first figure shows that the vehicle is bridged. The cable 60 is connected to indicate that the connection state is reversed, and in this state, the shielding layer is not connected to the vehicle body 101 on either side. The shielding layer 86 is in the connected state shown in Fig. 10. Since the vehicle bridge 86 is not grounded, the shielding effect on the external noise is less. The train information transmission and reception system shown in the figure is changed if the vehicle is changed. 2〇] The direction of the direction|J will become the connection state as shown in Fig. u, and the connection state of the first 〇: is also the same as the connection state shown in Fig. 1G, and the shielding effect of external noise is small. In order to secure the grounding state as shown in Fig. 9 to obtain a sufficient external shielding effect, it is necessary to consider not only the direction of the vehicle jumper cable 6G but also the direction of the vehicle surface 201 to connect the vehicle 201. In the train information transmission and reception system shown in Fig. 12, the shield layer of the twisted pair of wires 8b of the vehicle jumper cable 60b is not in the direction of the vehicle body grounded vehicle crossing the 'twist line 60b' or the vehicle light 201 Even if the direction is changed, the same connection state is still used. Therefore, when the train is connected, it is not necessary to consider the direction in which the vehicle jumps over the cable 60b or the vehicle 201, but the point of sufficient external noise shielding cannot be obtained. On, then on the 1st and n The connection state shown in the figure is the same. Fig. 13 and Fig. 14 are views showing an embodiment of the train information transmitting and receiving system 205 of the present invention. As shown in Fig. 13, in each of the vehicles 2〇1, 2〇1 The second and second vehicle-side splicers 21a and 22a provided at both ends of the vehicle have grounding terminals 21b and 22b that are grounded to the vehicle bodies 101 and 〇1 of the vehicles 201 and 201 via the shielded grounding wires 100 and 100, and Two signal transmission path terminals 21c and 22c of two (multiple 11 320930 201026537). The first and second in-vehicle distribution cable lines 21 and 22 have a plurality of signal transmission paths 25 and 25, and the transmission path is Two (multiple) signal transmission path terminals 21c, 22c of each of the first and second vehicle-side connectors 21a, 22a are connected to the information transmitting and receiving device 10, respectively; and the shielding layers 26, 26' are grounded to the vehicle 2车 1, 2 〇 1 body ι 〇 1, ι 〇 1 and a plurality of signal transmission paths are shielded. 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 thereof. 22b and a plurality of signal transmission path terminals 21c, 22c are bridged to the ground terminals 61b, 62b and a plurality of first and second jumper connectors 61, 62 of the crossover signal transmission path through the terminals 61c, 62c; And a plurality of crossover signal transmission paths 85, 85 connecting the plurality of crossover signal transmission routing terminals 61c, 62c of the first and second jumper connectors 61, 62 to each other; and the shielding layer 86 The plurality of cross-over signal transmission paths 85 and 85 are shielded and connected only to the side of the grounding terminal (four) and 62b of each of the second and second jumper connectors 6 and 62. That is, the train information transmission and reception system of the embodiment shown in Fig. 13 is to connect the shield layer % of the twisted pair cable 8 to the jumper connector 61 of the vehicle jumper line (1). The grounding terminal 6ib is connected to the grounding terminal 62b of the other (second) jumper connector 62, and is connected to the side of the vehicle 201, 201, and grounded to the vehicle body 1〇1, 1〇1 320930 12 201026537 If the vehicle is connected to the second vehicle side connector 2; the t 61 and the 62 are connected to the first!, the single body 101 is connected to the shield 86. Connected to the fourth/fourth, the figure shows the state in which the vehicle jumper cable 60 is connected first and reversely to the connection shape shown in Fig. 13, even in this state, the shield layer is connected only to the single body. 1 (n. As described above, even if the direction of the vehicle crossing gauge 60 and the vehicles 201, 201 is not considered, the shield layer 86 of the vehicle crossing the ground line 60 can be grounded only to one of the vehicle bodies 1〇1. The jumper signal transmission path of the jumper cable 60 may also use a plurality of shielded wires 33 instead of the twisted pair wires 80.
