る。According to the present invention, the entire insulating resin is injected into the gap between the iron core II+ and the molding die uz, and the coil winding part i2+ of the iron core Il+ is
Since the bobbin [AJ7] is formed in one piece with an insulating resin layer on the bobbin, unlike the conventional method where the bobbin is immediately coated with insulating paint, the thickness of the bobbin (... As a result, the curvature of the coil winding surface of the bobbin (8) can be freely set. Therefore, the winding of the coil becomes better.
The collar part T911101, the terminal mounting part or the lead wire guide part, etc. can be integrally molded at the same time as the body part (8) of A), and the coil winding part 12i can be integrally formed with an insulating layer and a bobbin (AJ). You can maintain the effects of what you did.

。In addition, a groove ■If' is provided on the outer end surface of the coil winding part (2) of the iron core H1 over almost the entire length in the stacking direction, and a thermoplastic insulating resin dissolved in madder temperature is provided in the groove insulation layer J. The protrusion Et-H1 #4 part + 8) which fits into the concave groove blocking j so as to fill the concave groove 21) is integrally formed with the concave groove 21), so the fitting between the concave groove - and the protrusion (24) It is possible to reliably prevent the bobbin (~ from being misaligned with respect to the coil winding part (2), and it is also possible to firmly fix the silicon steel plates of the iron core 111 to each other so that they do not become loose. .Moreover, by simply providing [!!J @ @11 k on the iron core II+,
The protrusion □t can be easily formed at the same time as the body (8) is formed;
It is easy to manufacture and can be provided at low cost, and its effects are significant.
