To be missing, the tree (four) Kona does not hide the installation of other elements. Referring to the fourth to seventh figures, when assembling the electrical connector, first, the first and second upper modules 3 (H, 303 are respectively shocked on the lateral end edge portion 23 of the aforementioned built-in circuit board 2). On both sides, the protrusions 3n and 313 of the first and second upper terminal modules 301 and 303 are respectively inserted into the matching holes 230 of the built-in circuit board 2 while the first upper terminal module 3〇1 is The positioning post 315 is inserted into the second module 303=the positioning hole 317. At this time, the lateral end edge portion 23 of the built-in circuit board (9) is partially received and formed in the first and second upper terminal modules 3〇3〇3 The slots between the first and second lower terminal modules 40 403 are mounted on the built-in circuit board 2 as described above. Then, the upper terminal module 3 (1) will be mounted. 3〇3 and the lower terminal module, the longitudinal end edge portion 21 of the built-in circuit board 20, the insertion slot 5ΐ on the card edge connector 5, and the conductive sheet 210 on the built-in circuit board 20 and the terminal slot 512 The adapter terminals are connected. Finally, the upper terminal module 30 303, the lower terminal module, the backup, the built-in circuit board 2 () and the card edge connector 50 are integrally assembled to the insulative body. As described above, the electrical connector assembly of the present invention shares a built-in circuit board by using the upper and lower cymbals to make full use of the space of the circuit board, thereby saving the space occupied by the built-in circuit board inside the insulating body. It has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above-mentioned preferred embodiment of the present invention (4) is limited to the above-mentioned embodiments, and those skilled in the art can assist the invention. The equivalents (4) or variations of the spirit should be covered by the following patent application. 200952267 [Simplified description of the drawings] Fig.: Fig. 1 is an exploded view of the electrical connector and the mother circuit board of the first embodiment of the present invention.
