させて接続導通させる構造になっている。2. Description of the Related Art As shown in FIG. 2, a press contact terminal presses an as-coated wire 3 into a flat press contact blade 2 having a U-shaped slot 1 by pressing it with a press contact press die 4, and press-fits the wire. The wire coating is cut by the edge of the wire, and the edge of the press-contact blade 2 and the wire conductor are pressed into contact with each other to establish connection and conduction.

れている。In the press-contact processing, the press-contact terminal 5 is inserted into the terminal accommodating chamber 7 of the connector housing 6 in advance, and the tip of the metal lance 8 of the press-contact terminal 5 is engaged with the step-shaped locking portion 9 of the terminal accommodating chamber 7. The insertion position is locked, and the pressure contact terminal 5 in the insertion position is locked.
From above, there is provided a processing means for press-fitting the electric wire 3 by a press-contact press die 4 having a clearance clearance 10 for avoiding a press-contact blade.

合がある。[Problem to be Solved by the Invention] However, the press-fitting terminal 5 inserted into the terminal accommodating chamber 7 has a slightly insufficient insertion amount, and the metal lance 8 and the locking portion 9 are not fully engaged. In order to prevent this, the metal lance 8 is inserted with a margin so as to have a slight play space C between the tip of the metal lance 8 and the locking portion 9, and the insertion position in the mass production process is physically restricted. The press-contact terminals 5 which are not used naturally have a variation in the front and rear positions of the terminal accommodating chamber 7.
There is a problem that the front-rear position of the press contact blade 2 with respect to fluctuates within a certain range.

Corner press-fit point 13
Electric wire 3 whose span L becomes large and receives large press-in resistance
As shown in FIG. 2 (C), the portion of the wire 3 that has been caught in the press-contact blade 2 escapes upward, and as a result, the press-fit amount of the electric wire 3 becomes insufficient and the press-contact becomes unstable.

いる。"Means for Solving the Problems" The wire pressure welding method of the present invention for solving the above technical problems is described below with reference to FIG. 1 showing the basic concept of the present invention.
The U-shaped slot 1 of the press-contact blade 2 of the press-contact terminal 5 having the terminal locking mechanism including the metal lance 8 on the terminal side and the locking portion 9 on the terminal housing chamber side has an escape clear lance 10 for avoiding the press-contact blade in the middle. When the electric wire 3 is press-fitted and press-fitted by the press-fitting press mold 4 having the metal lance 8, the metal lance 8 of the press-connecting terminal 5 is overrun and inserted into the locking portion 9, and then from the front of the terminal accommodating chamber 6. The positioning projection 12 of the positioning jig 11 is pushed in, the tip of the metal lance 8 is brought into contact with the locking portion 9 to regulate the position, and the electric wire 3 is pressed and connected at the regulated position.
