Importantly, in the electrical connector combination of the present invention, the plug connector 200 can be inserted into the receptacle connector in both forward and reverse directions. It can be understood that, in order to achieve positive and negative insertion, the mechanical structure of the docking cavity of the socket connector 300 and the mechanical structure of the plug connector must be symmetrical about the central axis.

Figures 13 to 15 are similar to the receptacle connectors of the previous embodiments, mainly showing two points. First, the shielding plate 34 is buried in the tongue plate and surrounds the plane of the entire docking tongue plate 313 ′, so that when the plug connector 200 or other non-matching plug connectors are improperly inserted, for example, the left and right sides are inserted obliquely At this time, the shielding plate 34 made of metal can effectively prevent the butt tongue plate 313' made of plastic material from being damaged by impact. The second point is that the shielding plate 34 is clamped between the insulators of the upper and lower terminal modules, so that the butt tongue has a certain degree of elasticity, so that when the plug connector is inserted with a certain inclination in the up and down direction, it can be avoided. The impact of the butt tongue plate 313' along the up and down direction is broken.

Fig. 16 to Fig. 22 have shown the receptacle connector 400 of the second embodiment, and this receptacle connector is installed on the circuit board 401, and it comprises metal shell 45 and terminal module combination 41, and terminal module combination 41 comprises upper and lower terminals The modules 411, 412 and the tongue piece 413 with a shielding plate sandwiched between them are stacked and assembled together in the vertical direction to form a terminal seat, and the front end of the tongue piece forms a butt tongue 413', Both the upper and lower terminal modules are embedded with terminals 421, 422, and the contact parts of the terminals are arranged on the butt tongue plate 413'.

On the other hand, when the plug connector is inserted into the initial state as shown in FIG. 23 , other terminals of the plug connector can contact the front edge of the shielding plate 44 . The thinned front edge 442 can allow the front end of the corresponding terminal to move elastically inward, thereby forming a guiding front end, which plays a better fixing role and facilitates insertion, and avoids the risk of short circuit. The shielding plate 44 is provided with a thin-shaped area 446 at its rear end, and the thin-shaped area 446 is just aligned with the high-speed signal terminals, so as to improve the electrical performance of the high-speed signal terminals.
