In such a configuration, when a high-frequency current is supplied to the power supply lines 3 and 4 by a high-frequency power supply (not shown), the power receiving core 6 having a low magnetic resistance becomes a magnetic path and generates a magnetic flux Φ. When electric power is generated in the coil 7, non-contact power supply is performed on the moving body.

The thickness of the center leg 6a and the thickness of the coil 7 cannot be made narrower than the sum of the thicknesses.
The inductance is increased by an amount corresponding to an increase in the interval between the four.

It is necessary to wind around d and 6e, that is, since the coil winding place is divided into two places, the man-hours for coil winding work and wiring connection work increase, and workability is remarkably deteriorated. Resulting in.

Therefore, it becomes very difficult to automate the coil winding operation. An object of the present invention is to provide a non-contact power supply device capable of reducing the inductance of a power supply line without complicating a coil winding operation and a wiring connection operation in view of the above conventional problems. .

That is, the present invention is provided on a feeder line including a forward path and a return path, which are arranged along a predetermined track, and a moving body that moves on the track.
In a non-contact power supply device including a power receiving unit for receiving power from the power supply line in a non-contact manner, the power receiving unit includes a power receiving core having an E-shaped cross-sectional shape, and the power receiving core. A coil wound intensively at the base of the central leg (or the outer leg), wherein each of the feed lines on the outward path and the return path is connected to each of the central leg and the outer leg of the power receiving core. Located in the gap, there is no overlap between the power supply line and the coil when viewed from the outer leg side of the power receiving core, and at least the power supply line and the coil are viewed from the open side of the power receiving core. It is characterized by partially overlapping.

とが可能となる。In this case, the power supply line and the coil only need to overlap at least partially when viewed from the open side of the power receiving core, and this alone reduces the distance between the power supply lines by the overlap. ing. Of course, by making them all overlap, it is possible to narrow the interval between the power supply lines most.

敷設距離を長くすることも可能となる。Since the distance between the power supply lines can be reduced in this manner, the inductance can be reduced as much as possible. As a result, the voltage between the output terminals of the high-frequency power supply for flowing the high-frequency current through the power supply line can be suppressed. Therefore, the laying distance of the power supply line can be increased.

In order to wind the coil, it is only necessary to wind the coil on such a bobbin in advance and insert it into the leg of the power receiving core, so that the winding process and the assembling process can be easily automated. become. Of course, such a configuration that does not use a bobbin is also within the scope of the present invention.

And a coil 17 wound around the base of the central leg 16 a of the power receiving core 16. The coil 17 is wound around a bobbin 18 that can be inserted into the center leg 16a of the power receiving core 16, and the coil 1 is thus wound.
The wound bobbin 18 is inserted into the base of the central leg 16a.

7, the center leg 16a and the outer leg 16 are thus narrowed.
Each of the two power supply lines 13 and 14 is located in each gap with b and 16c.

And the coil 17 do not overlap at all, and the power receiving core 1
When viewed from the open portion side of 6 (that is, when viewed from the direction of arrow B), the feed lines 13 and 14 are in a positional relationship such that the entire feed lines 13 and 14 completely overlap the coil 17.

That is, when a high-frequency current is supplied to the power supply lines 13 and 14 by a high-frequency power supply (not shown), the power receiving core 16 having a low magnetic resistance becomes a magnetic path to generate a magnetic flux Φ. , A non-contact power supply is performed to a traveling motor or the like which is a driving source of the moving body.

Since the distance between the feed lines 13 and 14 can be reduced in this way, the inductance can be reduced as much as possible. As a result, the voltage between the output terminals of the high-frequency power supply for flowing the high-frequency current through the feed lines 13 and 14 can be reduced. Keep it low,
The laying distance per feeder line can be increased.
