および生産性が悪いという問題点があった。Since the conventional coil manufacturing method is configured as described above, the outer circumferential surface of the coil obtained after heat curing is not smooth due to unevenness due to resin flow, foaming, and unevenness of the coil finish m. However, in order to obtain a coil with a smooth surface, adjustment work on the coil surface is required after heating and curing, resulting in poor workability and productivity.

て加熱硬化するようにしたものである。The method for manufacturing a coil according to the present invention is to place an insulating base material impregnated with resin and made into a semi-hardened state around the outer periphery of a coil formed by winding a coil conductor, and then heat-cure by attaching a metal plate to the outer periphery of the insulating base material. It was designed to do so.

のであったが、他のコイルにも適用可能である。The method of manufacturing the coil is to form the coil in the same manner as before, then attach a metal plate (7) to the outer periphery of the outer circumferential taping layer (5), and then wrap the fixing tape (8) around the outer periphery to fix it. . By heating and curing at a predetermined temperature for a predetermined time, the resin flowing out from the prepreg-treated insulating base material, tape, etc. is uniformly impregnated into the outer peripheral surface of the coil along the surface of the metal plate (7). As a result, the uneven portions are adjusted with the resin at the same time as the coil is wound, and a smooth outer circumferential surface is formed. After heating and curing, the metal plate (7) and the fixing tape (8) are removed from the coil to obtain a coil.6 Note that in the above example, the outer insulating base material (4) and the outer circumferential taping layer (5) are provided separately. However, one may be omitted. Furthermore, although the above embodiments relate to coils of molded transformers, they can also be applied to other coils.

る効果がある。As described above, according to the present invention, a metal plate is attached to the outer periphery of the insulating base material arranged around the outer periphery of the coil, and the metal plate is heated and hardened, so that a coil having a smooth outer periphery can be easily and inexpensively produced. In addition, there is an effect that work such as adjustment of the outer circumferential surface of the coil becomes unnecessary, resulting in a coil with high workability and productivity.
