During the manufacturing process, after the electrical connector 11 is assembled with the adapting circuit board 12, the electrical connector assembly 10 shown in fig. 2 is obtained, and the terminals 111 and the contact pad sets 122 are soldered together. Next, the electrical connector assembly 10 and the cable 20 are soldered to obtain the electrical wiring device 100. As shown in fig. 4, during soldering, the electrical connector assembly 10 is placed on the positioning fixture 200, the positioning posts 201 (which are cylindrical but not limited to) of the positioning fixture 200 are inserted into the positioning notches 124 to position the electrical connector assembly 10, the cable 20 is fixed, the cable 20 is aligned with the electrical connector assembly 10, the positioning fixture 200 is moved along the arrow direction, the electrical connector assembly 10 is close to the cable 20, the wires 21 are respectively lapped to the contact pad sets 122, soldering is performed, and the electrical connection device 100 shown in fig. 1 is obtained after soldering.

Preferably, the positioning notch 124 is a circular hole structure in the form of a 2/3 circle.

As shown in fig. 5, the circuit board assembly 300 of the present invention includes a plurality of adapter circuit boards 12, and the plurality of adapter circuit boards 12 are connected in a row. The outermost relay circuit board 12 is connected to a structural body 310, the structural body 310 is arranged along the arrangement direction of the relay circuit board 12, and the structural body 310 is provided with a reference positioning hole 311.

In the above-described embodiment, the connecting body 314 does not close the positioning notch 124, i.e., the positioning notch 124 is completely open. In a variation of the circuit board assembly 300 shown in fig. 10, the connector 314 closes the positioning notch 124, and the fold structure 316 spans the positioning notch 124. By breaking the crease 316 and separating the connector 314, the positioning notch 124 can be left open, which is not understood to mean that the positioning notch 124 of this embodiment is completely closed. It should be noted that the reference positioning hole 311, the processing positioning hole 315 and the positioning notch 124 are processed simultaneously, and the three parts are processed by using the same processing reference, so that the error of the post-processing can be reduced.
