れ形設されている。(Example) Hereinafter, an example will be described in detail using the accompanying drawings. FIG. 1 and FIG. 2 show an embodiment of the present invention, and reference numeral 11 has flanges 12a and 12b at both ends.
A coil body 4 is constructed by winding a coil 3 on a coil bobbin equipped with a coil bobbin. In addition, coil bobbin 11
Alternatively, a plurality of intermediate flanges 14 may be provided outside the flanges 12a and 12b to divide the coil into separate windings. Tsuba 1
A plurality of terminal pins 15 to which the lead wires of the coil 3 are connected are implanted in 2a and 12b, respectively.
Furthermore, ribs 13a and 13b are formed at one end of each of the flanges 12a and 12b to prevent the I-shaped magnetic core 6a of the EI-shaped magnetic core and the gap paper 5 from shifting.

することができる。 In this embodiment configured as described above, when the EI-shaped magnetic cores 6a and 6b are incorporated into the coil body 4 and fixed with the U-shaped plate spring 7, the I-shaped magnetic core 6b is attached to the rib 1.
Since the paper contacts 3a or 13b and its position is regulated, no displacement occurs, and at the same time, the gap paper 5 also does not shift. Since the ribs 13a and 13b are set lower than the height of the I-shaped magnetic core 6b, the U-shaped leaf spring 7 can sufficiently tighten and fix the EI-shaped magnetic core.

むことができる。 In addition, since the ribs 13a and 13b at both ends of the flanges 12a and 12b are connected by ribs, the resin flows well through the ribs during molding of the coil bobbin, preventing deformation and distortion of the product. No more outbreaks. Furthermore, since the ribs for preventing displacement of the I-shaped magnetic core are provided on the flanges at both ends, the EI-shaped magnetic core can be assembled from either direction.
