At the same time, the elasticity of the elastic card block 413 itself is used to make the elastic card block 413 stick to the outer surface of the wire to fix it. Then the wire is inserted into the unlocking seat 403, and then the unlocking pressure plate 404 is pressed downward. The unlocking pressure plate 404 pushes the elastic sheet 406 to move downward and continues to push the wire forward until the guide is connected to the conductive member 405, and then the unlocking pressure plate 404 is released. The unlocking pressure plate 404 automatically resets using elasticity. The elastic sheet 406 also resets upward using elasticity because there is no downward pressure from the unlocking pressure plate 404, thereby fixing the wire, and the female connector 7 is also connected to the wire in the above method.
