Embodiment Construction

[0068] Hereinafter, the contactless power supply device of the present invention will be described in detail based on the preferred embodiments for implementing the present invention shown in the accompanying drawings.

[0069] FIG. 1 and FIG. 2 are for the description of the preferred embodiment for carrying out the present invention. 1 is a plan view of the primary side, that is, a view viewed from above (it is also a plan view of the secondary side, that is, a view viewed from above), and view (2) is a view of the primary side and the secondary side. A view is a cross-sectional view viewed from the front (side view, that is, viewed from a lateral direction).

[0070] Fig. 2 (1) is a front view of the electromagnetic coupling, that is, a cross-sectional explanatory view viewed from the front (side view, that is, viewed from a lateral direction), (2) is a front view of the magnetic flux distribution, and (4) Fig. An explanatory plan view of the eddy current, and FIG. (5) is ...

Abstract

This non-contact electric power supply device 6 is used to charge, for example, a battery of an electric vehicle, and electric power is supplied from a primary side, i.e., a primary coil 7 on an electric power supply side to a secondary side, i.e., a secondary coil 8 on an electric reception side based on a mutual induction effect of electromagnetic induction. The primary coil 7 and the secondary coil 8 are flatly and spirally wound in one plane, respectively, (by) making a plurality of parallel conducting wires a set and are twisted at a regular pitch interval along the way. A primary magnetic core 13 and secondary magnetic core 14 on which the primary coil 7 and the secondary coil 8 are disposed are made of ferrite and the like and are formed in a tabular shape. Outer surfaces of the primary coil 7 and the primary magnetic core 13 and outer surfaces of the secondary coil 8 and the secondary magnetic core 14 are covered and secured by molded resin 17, respectively. Foamed materials 18 are mixed in the molded resin 17.

Description

technical field [0001] The present invention relates to a contactless power supply device. That is, the present invention relates to a non-contact power supply device based on a mutual induction effect of electromagnetic induction. For example, it relates to a non-contact power supply device that charges the battery of a battery car from the outside in a non-contact manner. Background technique [0002] ( 1 ) of FIG. 4 is a perspective explanatory view for explaining the basic principle of a contactless power supply device of such a prior art. Regarding this basic principle, the conventional example is the same as that of the present invention. [0003] As shown in the same figure, there is known a non-contact power supply device 3 that supplies electric power from a primary coil to a secondary coil by mutual inductance of electromagnetic induction, and is used for charging a battery of a battery car, for example. [0004] That is, in the non-contact power supply device, ...
