It is also possible to arrange the rows of the socket terminals horizontally, and the pins of the two rows of socket terminals jointly hold the circuit board 592 instead of inserting the circuit board; or the horizontally arranged socket terminals of each row, the two rows of socket terminals The pins are surface-welded and soldered to a tilt-extending circuit board, ie the pair of connectors of the receptacle connector are vertically up and the board is tilted. The twenty-fifth diagram shows the receptacle connector 63, which is formed by a circuit board 631, such as an internal circuit board, which is connected to the circuit board 633 by other receptacle terminals 632.

26 to 27 show the electrical connector assembly of the third embodiment, and the socket insulating body of the socket connector 65 is formed by the upper and lower insulating bodies 651, 652 mounted on both end sides of the circuit board 653, and the circuit Board 653 can be the motherboard of a mobile device. The front edge of the circuit board 653 is provided with a pair of elongated openings 6531. The circuit board between the two elongated openings 6531 forms abutting tongue 654. The conductive pads 6532 on the circuit board are equivalent to the socket terminals. The upper and lower insulating bodies 651, 652 respectively include a pair of side walls 6511, 6521, and the side walls 6511, 6521 are respectively inserted into the elongated opening 6531, thereby the butt tongue The plate is surrounded therein to form a pair of interfaces 655 that extend into the pair of interfaces. The two side walls of the docked plug connector 66 are respectively inserted into the elongated opening 6531.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto. Equivalent modifications or variations made by those skilled in the art in the spirit of the present invention are still included in the scope of the appended claims.
