Abstract
PURPOSE: To obtain mold coil of stable quality by providing projections at both ends and inner periphery of coil winding portion of a bobbin to make contact with the inner surface of mold and core.
CONSTITUTION: Projections 11b is formed at axial both ends of a coil winding portion 11a of a cylindrical bobbin 11 of epoxy resin, and the length of the bobbin including the projection is equal to the core 3c of molds 3a, 3b to allow the end to contact with the inner surface of the mold. Accordingly, the bobbin is fixed at the upper and lower positions in the mold. Another projection 11c is provided on the inner peripheral surface of the bobbin to allow the end to make contact with the surface of the core 3c. When the core is inserted into the bobbin, the gap with the core is uniform and remained constantly. According to this configuration, the projection may be pushed away from the resin flown under pressure to thereby obtain a mold coil of stable equality.
