になすことか考えられている。Therefore, the ferrite core 15 fixed to the cable I2 as described above and the connector IO are connected and fixed by resin molding (primary molding) using a mold. A part of the vicinity of the base of the connector 10 and the ferrite core I5 are housed in a mold, and a molten resin such as polypropylene is filled and hardened to form the connector 10, the cable 12, and the ferrite core 15.
Consideration has been given to combining them integrally to regulate their relative behavior.
そして、このようにしてケーブルに固定されたフェライ
Ｉ・コアを含む一次成形品は、その外観。The appearance of the primary molded product containing the Ferrai I core fixed to the cable in this way is as follows.

。However, when secondary molding is performed by placing the primary molded product 17 in the mold 24 as described above, the resin pressure causes the primary molded product 17 to change as shown by the dashed line in FIG. It is pushed and swung so that it is biased towards a specific wall surface within the mold 24. If the resin for secondary molding hardens under such conditions, the thickness of the resin around the primary molded product 17 may become uneven, which may seriously impair its appearance.
