Figure 24 shows a receptacle connector 59 in which each row of receptacle terminals 591 are arranged side by side in a vertical plane and mounted on a circuit board 592 with the interface 593 extending obliquely upwardly with the receptacle terminal 591 passing The terminal locating member 594 is positioned; in other embodiments, each row of the socket terminals 591 of the socket connector 59 are arranged in a lateral direction perpendicular to the vertical direction, the interface is inclined upwardly, and the socket terminal 591 is inserted into the circuit board 592; For each row of socket terminals, the pins of the two rows of socket terminals jointly hold the circuit board 592 instead of inserting the circuit board; or the rows of the socket terminals can be arranged horizontally, and the pins of the two rows of socket terminals are Surface soldered and soldered to a tilted circuit board, ie the socket connector is vertically up and the board is tilted Oblique setting. Figure 25 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. The socket insulating body of the receptacle 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 a mobile device. Mother board. 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, respectively, into which the side walls 6511, 6521 are inserted, so as to surround the butt tongues therein, forming a pair of interfaces 655, the butt tongues extending into the pair of interfaces. The two side walls of the docked plug connector 66 are respectively inserted into the elongated opening 6531.
