いるなかで、特性向上の為重要視されている。Structure of conventional examples and their problems In recent years, insert molding has been increasingly used for resistor eccentric stoppers in the manufacture of electronic components, and more and more insert molding is being used in composite molding of resistors with resin. It is considered important for improving characteristics.

成形金型においてインサート成形すると、ゲート位置が
中央部にない為、抵抗体が樹脂の射出圧力によって偏心
、あるいはわん曲してし１うという欠点を有していた。First, although the terminal part is omitted in Figure 1, when the resistor is insert-molded in a mold, the gate position is not in the center, so the resistor may become eccentric or curved due to the injection pressure of the resin. It had one drawback.
そして、もしゲートを中央部にもってきて、ゲート位置
を三箇所左右対称に配置しても完全に左右のバランスを
とることは困難であった。Even if the gates were brought to the center and the gate positions were arranged symmetrically in three locations, it was difficult to achieve perfect left-right balance.
発明の目的
本発明は上記欠点に鑑み、抵抗体の偏心を最小限にとど
める為の抵抗体偏心止めを提供するものである。OBJECTS OF THE INVENTION In view of the above drawbacks, the present invention provides a resistor eccentricity stop for minimizing the eccentricity of the resistor.
