Abstract

PURPOSE:To propose a linear slider type non-contact power supply device of a firm construction without increasing self inductance of a primary coil. CONSTITUTION:Primary cores (such as a core and a ferrite core) 1a to 1f wound with a primary coil 4 are divided and arranged at a regular interval, and a clearance therebetween is charged with fillers 2a to 2e such as resin of non- magnetic and non-conductive material. A size L2 in a movement direction of the secondary core (such as a core and a ferrite core) 5 which is wound with the primary coil and a secondary coil 7 which moves on the primary core is made integral multiple of a size L1 which is a sum of a size of the primary core and an interval distance.

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.

In order to solve the above-mentioned problems, in the present invention, the primary side core (iron core, ferrite core, etc.) around which the primary side coil is wound is divided and intermittently arranged at equal intervals. 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 ...).

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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. 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.
