度な小形接点を容易に製造することが可能となる。[Effects of the Invention] As described above, according to the present invention, the inclined surface is provided on the contact and the inclined surface is also provided on the terminal conductor so that the contact is positioned and pressed by the electrode, so that the contact is accurately positioned at a predetermined position. Thus, it is possible to easily manufacture small contacts with high precision.
また傾斜面を設けて溶接するので従来のような曲げ加
工が不要となり、さらに電気溶接により接点を端子導体
先端部に取付けるのでかしめ加工するための高価な金型
が不要となり、コストを低減することができる。In addition, since the inclined surface is provided for welding, the conventional bending process is not required. Furthermore, since the contact is attached to the tip of the terminal conductor by electric welding, an expensive mold for caulking is not required, thereby reducing the cost. Can be.
また、位置決めガイドを用いることにより接点を所定
位置に正確にガイドして位置決めできるので高精度な接
点を得ることができるものである。Further, by using the positioning guide, the contact can be accurately guided and positioned at a predetermined position, so that a highly accurate contact can be obtained.
