As shown in FIG. 10, the power line introducing device 10 is disposed, for example, across the connecting portion 22a and the folded portion 23a. The connecting portion 22a and the pair of power supply lines 20 and the power supply device 24 are connected to each other. 23a is adjacent to the connecting portion 22a, and is a folded portion in which the power supply line 20 is disposed. In the insulated sliding wheel 50, the overhead wires 20z connected to the folded portion 23a are electrically connected to each other by the second power line 21b, the terminal block 29, and the fourth power line 21d. Further, in the insulating sliding wheel 50, an off-line portion 10za in which adjacent overhead wires 20z are spatially separated from each other is formed between the connecting portion 22a and the folded portion 23a. In addition, the offline portion 10za is illustrated in FIG.

However, compared with the present embodiment, in the case of the other insulated sliding wheel, when the power receiving portion passes between the connecting portion and the folded portion, if the connecting portion and the folded portion are spatially separated, there is a current flowing to the power supply line. The tendency of the generated magnetic field to drop. In the insulated sliding wheel, if the magnetic field generated by the current flowing to the power supply line drops, the output from the power receiving portion drops.

In particular, the insulated sliding wheel is formed such that the power receiving portion efficiently receives power from the power supply line and can output a predetermined stable power. In the insulated sliding wheel, the first power supply line has a different shape from the first connection terminal connected to the first power supply line, and has a magnetic field from the first power supply line interconnected with the power receiving coil, and The magnetic field of the first connection terminal interconnected with the power receiving coil is different. Further, in the insulated sliding wheel, the second power supply line and the second connection terminal connected to the second power supply line have different shapes, and a magnetic field from the second power supply line interconnected with the power receiving coil The magnetic field from the second connection terminal interconnected with the power receiving coil is different. Further, in the insulating sliding wheel, if the magnetic field generated in the off-line portion of the power supply line in which the first power supply line and the second power supply line are spatially separated expands and contracts, and the magnetic field density becomes low, the voltage in the power receiving portion becomes small.

As a result, in the power line introducing device 10, the power receiving coil 31b can be continuously supplied with power, and the magnetic amplification can be suppressed due to the overlap of the first lead portion 1ab and the second lead portion 1bb. Therefore, more stable power can be supplied.

In the power line introduction device 10, the power receiving portion 31 extends in a direction perpendicular to the longitudinal direction of the power supply line 20 so that the first extending portion 1ac and the second extending portion 1bc overlap each other and protrude from the gap 31aa.

In other words, the power line introducing device 10 extends by "the first extending portion 1ac extending along the direction intersecting the lead-out direction of the first lead-out portion" and "the direction intersecting the lead-out direction of the second lead-out portion" The second extension portion 1bc" is disposed to overlap each other, and the size can be reduced.

Moreover, the power line introducing device 10 is in the offline portion 10za, arranging both the first power supply line 20a and the first power line 21a in the parallel direction, and causing the current flowing to the first power supply line 20a and flowing to the first power line The direction of the current of 21a is the same. In FIG. 1, the direction of the current flowing to the first power supply line 20a and the second power supply line 20b is illustrated by a broken dotted arrow, and the current flowing to the first power line 21a and the second power line 21b is illustrated by a solid arrow.

The first connection terminal 1a and the second connection terminal 1b can suppress the magnetic field generated from the portion of the power supply line 20 and the offline from the power supply line 20 by adjusting the amount of overlap between the first lead portion 1ab and the second lead portion 1bb.

The distance from the overlap region of both the second lead-out portions 1bb may be also. Further, as shown in FIG. 5, the first width W1 indicates the length of the overlapping region in which both the first lead portion 1ab and the second lead portion 1bb overlap in the lead-out direction.

In the insulated sliding wheel 50 of the power line introducing device 10 of the present embodiment, it is possible to suppress the occurrence of an overvoltage in the output voltage output by the power receiving unit 31 when the magnetic field is received. In the case where the output current output from the power receiving unit 31 is too large in the mobile device 32, it is a cause of malfunction of the mobile device 32. The power line introducing device 10 of the present embodiment can supply more stable power to the mobile device 32 side in the off-line portion 10za of the power supply line 20.
