[0038] The PCB board integrated female socket 200 includes a PCB board body 210 and a plurality of lower terminals 220, and the plurality of lower terminals 220 are embedded in the PCB board body 210;

[0039] The male socket 100 includes a male socket body 110 and a plurality of upper terminals 120 , wherein the plurality of upper terminals 120 are disposed at the edge of the male socket body 110 ;

[0040] The number and positions of the plurality of upper terminals 120 are arranged correspondingly to the number and positions of the plurality of lower terminals 220 .

[0041] In the embodiment of the utility model, an integrated PCB mother seat is adopted, and a plurality of lower terminals are embedded into the PCB body by utilizing a terminal-embedded PCB design, which can be directly produced in an integrated manner, thus saving the subsequent welding process of the mother seat and improving the alignment and snap-fitting efficiency of the board-to-board connector.

[0042] See also Figure 3 As a preferred embodiment of the present invention, a first positioning hole 211 and a second positioning hole 212 are provided on the PCB board body 210 .

[0043] The provision of the first positioning hole 211 and the second positioning hole 212 improves the accuracy of the alignment and buckling of the male and female seats, and is also conducive to automation, such as automatically capturing the shape of the positioning holes, such as the coordinates of a circle or a parallelogram, for automatic alignment and buckling.

[0044] As a preferred embodiment of the present invention, please refer to Figure 3 The first positioning hole 211 and the second positioning hole 212 have different shapes. For example, the first positioning hole is circular, and the second positioning hole is a parallelogram. This arrangement can prevent the two from being buckled in the opposite direction.

[0045] As a preferred embodiment of the present invention, please refer to Figure 2 and Figure 4 , a first positioning column 111 and a second positioning column 112 are provided below the male seat body 110;

[0047] The shape of the second positioning column 112 is the same as the shape of the second positioning hole 212 .

[0048] The above arrangement enables the male and female sockets to be precisely aligned when they are buckled together. They can only be buckled together when the upper and lower parts match each other, which ensures the accuracy of the alignment and buckling of the male and female sockets, prevents the upper / lower terminals from being misaligned and having poor contact, and makes the connection of the connector more accurate and stable.

[0049] As a preferred embodiment of the present invention, a grounding sheet is provided on each of the first positioning column 111 and the second positioning column 112.

[0052] The first protruding portion 221 and the recessed portion 222 are disposed outside the PCB board body 210;

[0053] The second protrusion 223 and the lower terminal pin 224 are embedded in the PCB board body 210 .

[0054] As a preferred embodiment of the present invention, the upper terminal 120 includes a first buckle portion 121 . After the upper terminal 120 and the lower terminal 220 are assembled, the first buckle portion 121 fits with the recessed portion 222 .

[0056] As a preferred embodiment of the present invention, please refer to Figure 6 The upper terminal 120 also includes a second snap-on portion 122 and an upper terminal foot 123. The first snap-on portion 121, the second snap-on portion 122 and the upper terminal foot 123 are connected in sequence. The second snap-on portion 122 is clamped on the terminal fixing portion 113. The upper terminal foot 123 is used for welding other PCB boards.

[0057] Among them, through the above settings, see Figure 7 When the upper terminal 120 and the lower terminal 220 are aligned and buckled, the upper terminal 120 of the male seat 100 will be slightly bounced open by the first protrusion 221 of the lower terminal 220 of the female seat 200. When the lower terminal 220 is pressed into place, the first buckle portion 121 will fit with the recessed portion 222, and the first buckle portion 121 is clamped by the first protrusion 221 and the second protrusion 223, thereby increasing the contact area of ​​the upper / lower terminals and making the connection of the upper / lower terminals more stable, thereby enhancing the stability of signal transmission. The above arrangement also facilitates the insertion and removal of the upper terminal and is not easy to damage the terminal. In addition, the second buckle portion 122 is clamped in the terminal fixing portion 113, thereby avoiding welding between the upper terminal and the male seat, and facilitating the installation of the upper terminal 120.
