本発明は、電線接続用圧着端子の製造方法に係り、特に
電線接続用円筒部に継目の無い圧着端子を得るに好適な
圧着端子の製造方法に関する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a method for manufacturing a crimp terminal for connecting electric wires, and particularly a method for manufacturing a crimp terminal suitable for obtaining a crimp terminal with a seamless cylindrical portion for connecting electric wires. Regarding.
従来、電線接続用圧着端子は、第３図に示すように、導

は、溶接し製作するものであった。なお、展開形状主を

同時に形成するのが一般的である。Conventionally, as shown in Fig. 3, crimp terminals for connecting electric wires are made by cutting out the developed shape of the crimp terminal with a seam as shown in (A) using a flat plate material 10 made of conductive metal as a material, and then (B).
) After separating the unfolded shape by pressing, round it by pressing to form the cylindrical part 11 for connecting electric wires as shown in (C), and then braze or weld the seam 12. It was to be manufactured. Incidentally, when the main developed shape is separated from the flat plate by press work, it is common to form the screw attachment holes 6 at the same time.

させる恐れがある。This manufacturing method involves many manufacturing steps and wastes materials.
In particular, the work of brazing or welding the joint 12 of the cylindrical part 11 for connecting electric wires requires time and skill, and the production efficiency is low. It is difficult to obtain the roundness of the portion 11, especially around the joint 12.Furthermore, when the joint 12 is brazed or welded from outside the cylinder, the brazing or welding material may be attached to the electric wire. Flows into the inner surface of the connecting cylindrical part 11,
Further inhibiting the roundness of the inner surface of the cylindrical portion 11 for connecting electric wires,
As a result, when the core wire of the electric wire is inserted into the cylindrical portion of the wire connection cylindrical portion 11 during crimping work, the core wire is likely to break at the seam 12, reducing work efficiency and being unfavorable in terms of quality. If there is a soldering or welding defect in the joint 12, there is a risk that the joint 12 will separate during crimping, resulting in poor crimping.
このため、電線接続用円筒部１１に継目１２を持たない
圧着端子の製造方法として例えば、特開昭４８−８２３

又。For this reason, as a method for manufacturing a crimp terminal that does not have a seam 12 in the cylindrical portion 11 for connecting electric wires, for example, Japanese Patent Laid-Open No. 48-823
As shown in Publication No. 84, a method of manufacturing crimp terminals from a cylindrical material made of conductive metal has been proposed, but according to this method, cutting is required when forming the cylindrical part during the manufacturing process. production efficiency is low and material waste occurs. In addition, it is difficult to reduce the wall thickness of this cylindrical portion, and the center of the cylindrical portion is likely to shift relative to the cylindrical outer shape.
or.
肉厚を均一化する技術が難しい等の欠点がある。There are drawbacks such as difficulty in making the thickness uniform.
