In this lead frame, a terminal portion 21 serving as a terminal of a bobbin is formed to protrude from two parallel frames 22, and a connecting portion 23 is formed for reinforcement between the two parallel frames. Then, it is placed at a predetermined position on this lead frame, and resin is integrally molded to form a bobbin with a terminal. This situation is shown in FIG.

【発明が解決しようとする問題点】従来のように、リー
ドフレームに一体に樹脂成形してボビンを形成する方法
では、樹脂の収縮率とリードフレームの収縮率の違いか
ら、ボビンが変形するといった問題点があった。[Problems to be Solved by the Invention] In the conventional method of forming a bobbin by molding resin integrally with the lead frame, the bobbin may be deformed due to the difference in shrinkage rate of the resin and that of the lead frame. There was a problem.
【０００４】本発明は、上記の事を鑑みて、ボビンの変
形の起こらない製造方法を提供することを目的とする。In view of the above, an object of the present invention is to provide a manufacturing method that does not cause deformation of the bobbin.

This lead frame has terminal portions 2 that serve as bobbin terminals protruding from two frames 1, and a connecting portion 3 that connects and reinforces the two frames. And the middle part of the connecting part 3 is
It has a thin wavy portion 4. This lead frame was integrally molded with resin to produce a bobbin with terminals.
【０００８】本実施例によれば、成形された樹脂が収縮

、変形のないボビンを作製することができた。According to this example, the corrugated portion 4 of the lead frame contracts as the molded resin contracts, making it possible to produce a bobbin without deformation.
【０００９】尚、発明に係るリードフレームは、端子付
きボビン以外でも有効であることは言うまでもない。It goes without saying that the lead frame according to the invention is also effective for applications other than bobbins with terminals.

を提供することができる。According to the present invention, the lead frame deforms in accordance with the contraction of the resin, thereby preventing the bobbin from deforming. Furthermore, by forming an expandable portion in a part of the lead frame, it is possible to provide products with ease of manufacture in all kinds of applications.
