[0027] More specifically, in order to solve the assembly problem of the seat base assembly 11 in the entire socket connector, as shown in Figure 4 As shown, the back end surface of the seat base 110 is provided with a boss 1101. The boss 1101 can ensure that the pin root metal part of the jack assembly terminal 111 does not contact the printed circuit board, and can avoid the phenomenon of impedance reduction due to the too close distance between the root metal of the jack assembly terminal 111 and the PCB trace.

The key position two 1401 is used in cooperation with a key groove on the plug-in end face of the plug connector. When the socket connector in the embodiment is plugged and matched with the plug connector, the coding assembly 14 on the plug-in end face of the socket shell 10 has the effect of preventing wrong plugging. In the embodiment, different installation directions of the coding piece 140 can be adjusted to realize the combination of various anti-misplug coding.

[0031] In order to solve the assembly between the socket shell 10 and the coding assembly 14, as shown in the drawings, Figure 2 、 Figure 8 、 Figure 10 the plug-in end face of the socket shell 10 is provided with a mounting cavity 105; the coding assembly 14 further comprises a coding fixing piece 141 assembled in the mounting cavity 105, and the coding fixing piece 141 is provided with an arc-shaped convex portion two 1410.

After the coding piece 140 is assembled on the coding fixing piece 141, the coding piece 140 can be freely rotated to adjust the direction of the key position two 1401, so as to realize different coding.

[0033] The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same.
