いる。2. Description of the Related Art Conventionally, a linear slider type non-contact power supply apparatus is disclosed in Japanese Patent Application Laid-Open No. 56-140609 (Japanese Patent Publication No.
As shown in Japanese Patent Application Laid-Open No. 8-23723, a structure is known in which a primary coil is aerial wire, and an iron core with a secondary coil is slid in a shape including the primary coil. .

案するものである。However, in the prior art, the aerial wire of the primary coil is liable to be broken, and there is a problem of bending when it is long.
Embedding in the shaped core has a problem that the self-inductance of the primary coil in a portion not directly facing the secondary coil increases and the efficiency decreases. In view of the above, the present invention proposes a linear slider-type non-contact power feeding device having a strong structure without increasing the self-inductance of the primary coil as much as possible.

They are arranged and filled with a non-magnetic or non-conductive resin or the like. Further, the primary side coils and 1
The dimension in the moving direction of the secondary core (iron core, ferrite core, etc.) wound with the secondary coil that moves on the secondary core is the total of the dimensions of the primary core and the distance (array pitch) ) (N = 1, 2,...).

きるようになる。By the above means, the primary coil is firmly held by the primary core and the filling resin. In addition, by dividing the primary core and intermittently arranging it, permeance is lower (magnetoresis is increased) as compared with the case where the primary core is provided for all movable lengths, and the primary coil self Inductance can be reduced. Also, by adjusting the arrangement pitch of the primary cores and the dimensions of the primary cores, it is possible to suppress the fluctuation of the voltage induced in the secondary coil due to the position of the secondary cores, and to achieve a stable voltage. Be able to supply.

The primary side core is divided into 1 a - 1 f, alternating with filler 2a~2e nonmagnetic and nonconductive, is placed in each array pitch L 1. A primary coil 4 is wound in a slot 3 provided in a primary iron core. The non-magnetic and non-conductive fillers 2a to 2e are composed of the primary coil 4 and the primary cores 1a to 1f.
Also has the role of fixing. Reference numeral 5 denotes a secondary core having a secondary coil 7 in a slot 6 thereof. And, for example, FIG.
The secondary core 5 is supported via a gap so as not to contact the primary core so that the secondary core 5 can move in the longitudinal direction of the primary core. The drive of the secondary core 5 is controlled by a mechanism (not shown) in the longitudinal direction of the primary core. Dimension L 2 in the movable direction of the secondary side core is an integral multiple of the arrangement pitch L 1 of the primary side core. Thereby, voltage fluctuation due to the position of the secondary core can be reduced.
