Since the feeder lines are mechanically connected to each other, the feeder lines can be easily connected using a general tool at the construction site of the trolley system.

  Hereinafter, a non-contact power feeding system according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the trolley system 1 according to this embodiment includes a moving rail 2, a moving body 3, and a non-contact power feeding system 4.

  The moving rail 2 is fixed to a housing such as a factory or warehouse not shown, and guides the moving body 3 to be described later to the moving path. A straight portion, a bent portion, a curved portion and the like are formed on the moving rail 2 along the moving path of the moving body 3.

  The moving body 3 receives electric power in a non-contact manner by electromagnetic induction from a power supply line of the non-contact power feeding system 4 arranged along the moving rail 2, and drives the motor 31 based on the electric power to move. It moves along the rail 2.

  The non-contact power feeding system 4 supplies power to the moving body 3 by flowing a high-frequency current through a power feeding line routed along the moving rail 2. Hereinafter, an embodiment in which the present invention is applied to the non-contact power feeding system 4 will be described in detail.

  As shown in FIG. 1, the non-contact power supply system 4 according to an embodiment of the present invention includes a high-frequency power source 5, a joiner 6, and a power supply line 7.

  The high-frequency power source 5 generates a high-frequency current, and supplies the generated high-frequency current to a power supply line routed along the moving rail 2.

  The joiner 6 connects power supply lines 7 described later in a U shape, an L shape, or a linear shape, and electrically connects the power supply lines 7 to each other. There are three types of joiners 6, an end joiner 61, an L-type joiner 62, and a series joiner 63, according to the connection form.

  The feed line 7 is formed as an elongated body having a predetermined length, and the feed line hanger 8 is used to route the two lines of the forward path and the return path along the moving rail 2. At this time, the feeder lines 7 are connected by the joiner 6. That is, the power supply line of the non-contact power supply system 4 is formed by a combination of the joiner 6 and the power supply line 7. As shown in FIG. 2, the power supply line 7 includes a conductor portion 71 and an insulating portion 72.

  The conductor portion 71 has a double tube structure in which a tubular inner conductor tube 71a and an outer conductor tube 71b made of a conductor are concentrically arranged. The inner conductor tube 71a and the outer conductor tube 71b are connected by connecting ribs 71c provided on the outer periphery of the inner conductor tube 71a, and between the inner conductor tube 71a and the outer conductor tube 71b and the inner conductor tube 71a. Inside, an insulator 71d is packed.

  The insulating part 72 is formed in a cylindrical shape with a flexible insulator such as a synthetic resin, and the conductor part 71 is embedded in the central part. In addition, about the edge part 7a of the feeder 7, the insulating part 72 is not provided over predetermined length.

  Here, a method of connecting the power supply line using the crimp sleeve 9 will be described in detail with reference to FIGS.

  The crimp sleeve 9 used in this connection method has a cylindrical shape made of a conductor as shown in FIG. Specifically, the crimp sleeve 9 is used when connecting the power supply lines 7 arranged in a straight line in the straight portion of the moving rail 2. As shown in FIG. 3, the pair of feeders 7 with the conductor portions 71 exposed are inserted into the crimping sleeve 9 as shown in FIG. The feeders 7 are electrically and mechanically connected to each other by crimping the conductor portion 71 of the electric wire 7 and the crimp sleeve 9. At this time, the crimp sleeve 9 is formed with a recess 9a that sinks into the inside from the outer surface, and the recess 9a reaches the inner conductor tube 71a of the conductor portion 71 as shown in FIG. The inner conductor tube 71a and the outer conductor tube 71b are pressure-bonded. The concave portion 9 a also functions to prevent the power supply line 7 from coming off from the crimping sleeve 9.

  As is clear from the above description, according to the connection method of the non-contact power feeding system 4 and the power feeding line 7 according to an embodiment of the present invention, the pair of power feeding lines 7 with the conductor portions 71 exposed are inserted into the crimping sleeve 9. Since the feeders 7 are electrically and mechanically connected to each other by crimping the conductor portion 71 of the feeder 7 and the crimping sleeve 9, the feeders 7 are connected to each other using a general tool at the construction site of the trolley system 1. It can be easily connected.
