In the non-contact insulating trolley 50, a separating line portion 10za where the adjacent trolley wires 20z are spatially separated is formed between the connecting portion 22a and the folded portion 23a. The separation line portion 10za is illustrated in FIG.

  By the way, in the non-contact insulation trolley compared with this embodiment, when a power receiving part passes between a connection part and a return part, if the connection part and the return part are spatially separated, the current flowing through the feeder line There is a tendency for the magnetic flux generated in step 1 to decrease. In the non-contact insulating trolley, if the magnetic flux generated by the current flowing through the power supply line is reduced, the output output from the power receiving unit may be reduced.

  In particular, the non-contact insulating trolley is formed in a structure in which the power receiving unit can efficiently receive power from the power supply line and output predetermined stable power. In the non-contact insulating trolley, the first feeding line and the first connecting terminal connected to the first feeding line are different in outer shape, and the magnetic flux from the first feeding line interlinked with the receiving coil, the receiving coil and the chain There is a possibility that the magnetic flux from the intersecting first connection terminal 1a is different.

There is a possibility that the magnetic flux from the intersecting second connection terminal is different. The non-contact insulated trolley has a stable voltage when the magnetic flux generated at the separation part of the feeder line where the first feeder line and the second feeder line are spatially separated is distorted and the magnetic flux density is reduced. It tends to be difficult to feed the generated power.

  In the power line lead-in device 10 of the present embodiment, the installation member 2 is arranged so that the first extension portion 1ac and the second extension portion 1bc overlap so that continuous feeding can be performed to the power receiving coil 31b.

In other words, the power line lead-in device 10 includes a first extending portion 1ac extending in a direction intersecting with the derivation direction in the first derivation portion, and a second extending portion extending in a direction intersecting with the derivation direction in the second derivation portion. By overlapping 1bc, it becomes possible to reduce the size.

  Furthermore, the power line lead-in device 10 arranges the first power supply line 20a and the first power line 21a along the parallel direction in the separation line portion 10za so that the current flowing through the first power supply line 20a and the current flowing through the first power line 21a It is comprised so that a direction can be made to correspond. In FIG. 1, the direction of the current flowing through the first power supply line 20a and the second power supply line 20b is illustrated by a dashed white arrow.

  As shown in FIG. 1, the power line lead-in device 10 appropriately sets the length of the second extending portion 1bc and appropriately adjusts the distance H between the second derivation portion 1bb and the second power line 21b. It becomes possible to supply more stable power. Similarly, the power line lead-in device 10 sets the length of the first extending portion 1ac as appropriate, and adjusts the distance between the first derivation portion 1ab and the first power line 21a as appropriate, so that more stable power can be obtained.

The region to be defined can be defined as the amount of overlap between the first derivation unit 1ab and the second derivation unit 1bb. The first connection terminal 1a and the second connection terminal 1b are, for example, a first inclined part 1at and a second inclined part to the first derivation part 1ab in order to change an overlapping area with the first derivation part 1ab and the second derivation part 1bb. It can also be set as the structure provided with 2nd inclination part 1bt in the derivation | leading-out part 1bb.

  However, in a non-contact insulated trolley, when a mobile device having two power receiving units attached so as to straddle the part of the separation line is used, the mobile device can be downsized and reduced compared to a mobile device having one power receiving unit. It tends to be difficult to reduce costs.
