摘要： A noncontact coupler comprising a pair of magnetic cores 1, 1 each having a U-shaped open magnetic path, a primary coil L1 and secondary coil L2 being wound around said cores 1, 1 separately respectively, said coupler transmitting AC electric power between said primary and secondary coils L1, L2 by means of an annular closed magnetic path B formed by opposing in proximity both open magnetic face sides of said cores, wherein said primary and secondary magnetic cores 1, 1 are respectively split at least at their sides facing to each other, and a gap forming a spatial magnetic path is interposed between said split pieces. A diameter a of a medium leg 51 positioned inside an annular groove 52 around in which the coils L1, L2 are wound (housed) is set almost equal to a width b of the annular groove 52. These provide effects of lightening a noncontact coupler while securing its performance and improving handleability with enhancing tolerance for positioning of the primary and secondary cores.

摘要： A sheet transformer wherein a coil pattern is formed on each of substrates so as to constitute a coil substrate, a plurality of the coil substrates are overlaid in multiple layers to form a primary coil and a secondary coil. The primary coil and the secondary coil are overlaid such that the middle leg cores of EE type, EI type, EER type or EIR type cores are disposed in the center of the coils and both the outside leg cores are disposed outside the coils, thereby obtaining a magnetic coupling between the coils. A higher potential side of the primary coil and a higher potential side of the secondary coil are disposed in an opposed configuration so as to face each other.
