Finally, injection molding is performed into the accommodating space 101 through the injection molding hole to form an inner mold 122, so that the inner mold 122 encapsulates the PCB board 121 in the accommodating space 101.

[0031] Furthermore, the upper cover 13 is provided with a third positioning portion 13a and a fourth positioning portion 13b, and the first positioning portion 11a and the third positioning portion 13a are arranged in cooperation so that the base 11 and the upper cover 13 are positioned in the following manner: Figure 1 As shown, they are relatively fixed in the first direction X and / or Y, so that the base 11 and the upper cover 13 are positioned in the first direction X and / or Y by the first positioning portion 11a and the third positioning portion 13a, and the second positioning portion 11b and the fourth positioning portion 13b are cooperated to make the base 11 and the upper cover 13 relatively fixed in the second direction Z, so that the base 11 and the upper cover 13 are positioned in the second direction Z by the second positioning portion 11b and the fourth positioning portion 13b, thereby improving the convenience and efficiency of assembling the wire end connector 10. At the same time, the above-mentioned positioning method can withstand the filling pressure of the inner mold glue during the process of injection molding the inner film 122, improve the stability of the sealing glue, and avoid the occurrence of glue overflow and long burrs.

[0032] Optionally, one of the first positioning portion 11a and the third positioning portion 13a is a positioning protrusion, and the other of the first positioning portion 11a and the third positioning portion 13a is a positioning groove.
