いる。2. Description of the Related Art Conventionally, a linear slider type contactless power feeder is disclosed in Japanese Patent Application Laid-Open No. 56-140609.
As disclosed in Japanese Patent Application Laid-Open No. 8-23723), there is known a structure in which the primary side coil is installed in the air, and the iron core with the secondary side coil includes the primary side coil and slides. .

案するものである。However, in the prior art, the aerial overhead wire of the primary side coil is apt to be damaged, and there is a problem of bending when it becomes long, so that the E of the primary side coil is problematic.
The embedding in the shaped core has a problem that the self-inductance of the primary side coil in a portion not directly facing the secondary side coil increases, and the efficiency decreases. Therefore, the present invention proposes a linear slider type contactless power supply device having a strong structure without increasing the self-inductance of the primary coil as much as possible.

They are arranged, and a non-magnetic or non-conductive resin or the like is filled between them. Further, the primary coil and 1 arranged as described above
The size of the secondary core (iron core, ferrite core, etc.) wound with the secondary coil moving on the secondary core in the moving direction is the total of the dimensions of the primary core and the spacing distance (arrangement pitch ) Is an integer multiple (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. Further, by dividing the primary side core and arranging the cores intermittently, the permeance becomes lower (the magnetic resistance becomes larger) as compared with the case where the primary side cores are provided over the entire movable length, and the primary side coil self The inductance can be lowered. Also, by matching the arrangement pitch of the primary side cores and the dimensions of the primary side cores, fluctuations in the voltage induced in the secondary side coil due to the position of the secondary side cores can be suppressed, and a stable voltage can be obtained. Will be able to supply.

The primary cores are divided into 1a to 1f, and the primary cores are arranged alternately with the non-magnetic and non-conductive fillers 2a to 2e at every arrangement pitch L 1 . The primary coil 4 is wound in the slot 3 provided in the primary iron core. The nonmagnetic and non-conductive fillers 2a to 2e are used for the primary coil 4 and the primary cores 1a to 1f.
Also has the role of fixing. Reference numeral 5 denotes a secondary core, which has a secondary coil 7 in its slot 6. Then, for example, in FIG.
By the mechanism shown in FIG. 2, the secondary core 5 is supported via a space so as to be movable in the longitudinal direction of the primary core and not to contact the primary core. The secondary core 5 is driven and controlled in the longitudinal direction of the primary core by a mechanism (not shown). The dimension L 2 of the secondary side cores in the movable direction is an integral multiple of the array pitch L 1 of the primary side cores. As a result, voltage fluctuations due to the position of the secondary core can be reduced.
