<p>PURPOSE: To provide an electromagnetic device which is composed of three separate bodies of a core, a bobbin, and a spacer, and also is capable of improving the assembly work efficiency, with small dispersion of inductance. CONSTITUTION: This electromagnetic device is composed of a bobbin 2, on which a winding is wound and which has a plurality of flanges 6 such that they divide itself into primary side and secondary side at both ends, a pair of cores 1, which are installed at the bobbin 2 and form a closed magnetic path, a spacer 3, which forms a gap between the tips of a pair of cores 1, and a slit 8 which is made in one out of a plurality of flanges 6 so that a spacer 3 can be inserted. Accordingly, an electromagnetic device can be provided, which is constituted of three pieces of separate bodies of the core 1, the bobbin 2, and the spacer 3 and also which can improve the assembly work efficiency with small dispersion of inductance.</p> |
