It varies depending on parameters such as the tension at the time of peeling of the body, the shape of the crushing of the connection part of the plug terminal, the variation between material lots, and the variation of manufacturing conditions. By adopting, the connection strength is managed to be a predetermined value. When the connection strength has a predetermined value, a power plug having a predetermined connection strength can be obtained without the cord conductor coming out of the connection portion of the plug terminal due to the molding pressure at the time of molding the plug body.

ン中に簡単に組み込ませることができる。As described above, according to the method and the apparatus for determining the connection strength between the power cord and the electric connection terminal according to the present invention, the power cord and the electric connection terminal are held at a predetermined holding force.
Since a predetermined pressing force is applied to the power cord near the connecting portion for a predetermined time while the tension is being applied to determine the connection strength of the connecting portion, the manufacturing cost is not increased. It enables total inspection, and the connection strength test of the power cord and the electrical connection terminal can Maseru easily embedded into the production line of the power supply plug.
