[0030] See also Figure 1-2 An embodiment of the utility model provides a circular board-to-board connector, including: a male socket 100 and a female socket 200, both of which are circular, and a plurality of upper terminals 110 are arranged on the edge of the male socket 100, and a plurality of lower terminals 210 are arranged on the edge of the female socket 200, and the number and position of the plurality of upper terminals 110 correspond to the number and position of the plurality of lower terminals 210.

[0031] The male and female sockets of the present utility model are both circular in design. Under the same terminal spacing condition, the total number of upper and lower terminals can be increased, and the spacing and number of upper and lower terminals can be increased or decreased according to actual conditions. Compared with the terminals on both sides of the traditional rectangular connector, more terminal signals can be connected. Furthermore, the circular design facilitates the equal spacing of the upper and lower terminals, allowing the PCB to be flexibly placed during PCB welding, which improves the convenience of alignment.

[0032] As a preferred implementation of the present invention, the male seat and the female seat are both made of plastic.

[0033] As a preferred embodiment of the present invention, the upper and lower terminals are arranged at equal intervals.

[0034] As a preferred embodiment of the present invention, please refer to Figure 1-2 The top of the male seat 100 includes an irregular protrusion 120 .

[0035] As a preferred embodiment of the present invention, please refer to Figure 1-2 The top of the female seat 200 includes an irregular groove 220 , and the irregular groove 220 has the same shape as the irregular protrusion 120 .

[0036] The embodiment of the utility model adopts the matching design of irregular protrusions and irregular grooves, so that the male socket and the female socket can be accurately aligned when they are buckled together. Only when the upper and lower parts match can they be buckled together, which prevents the upper / lower terminals from being misaligned and having poor contact, making the connection of the connector more accurate and stable.

[0037] As a preferred embodiment of the present invention, please refer to Figure 1-2 A first grounding plate 130 is provided at the bottom of the male socket 100 , and the first grounding plate 130 protrudes from the bottom of the male socket 100 .

[0038] As a preferred embodiment of the present invention, please refer to Figure 1-2 , the first grounding plate 130 is a circular structure.

[0039] As a preferred embodiment of the present invention, please refer to Figure 1-2 A second grounding plate 230 is provided at the bottom of the female socket 200 , and the second grounding plate 230 protrudes from the bottom of the female socket 200 .

[0040] As a preferred embodiment of the present invention, please refer to Figure 1-2 , the second grounding plate 230 is a circular structure.

[0041] The circular first / second grounding plate design not only eliminates static electricity, but also has the function of pre-positioning PCB welding. When welding, only the upper / lower terminals on the outer periphery of the circle need to be aligned, avoiding welding deviation caused by accidental displacement when welding the PCB. Especially when the upper / lower terminals are set at equal spacing, the convenience of upper / lower terminal alignment is improved.

[0042] As a preferred embodiment of the present invention, please refer to Figure 3 and Figure 5 The upper terminal 110 includes a first protruding portion 111, a recessed portion 112, a second protruding portion 113 and an upper terminal pin 114 which are connected in sequence.

[0043] As a preferred embodiment of the present invention, please refer to Figure 4-5 The lower terminal 210 includes a first buckle portion 211 . After the upper terminal 110 is pressed onto the lower terminal 210 , the first buckle portion 211 fits with the recessed portion 112 .

[0044] As a preferred embodiment of the present invention, please refer to Figure 4-5 The lower terminal 210 also includes a second snap-on portion 212 and a lower terminal foot 213. The first snap-on portion 211, the second snap-on portion 212 and the lower terminal foot 213 are connected in sequence. The second snap-on portion 212 is used to snap on the edge of the female socket 200, and the lower terminal foot 213 is used to solder the PCB board.

[0045] Among them, through the above settings, see Figure 5 When the upper terminal 110 is pressed onto the lower terminal 210, the lower terminal 210 of the female socket 200 will be slightly bounced by the first protrusion 111 of the upper terminal 110 of the male socket 100. When the upper terminal 110 is pressed to the bottom, the first buckle 211 will fit with the recessed portion 112, and the first buckle 211 is clamped by the first protrusion 111 and the second protrusion 113, 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.

[0046] The design of the upper / lower terminal pins makes the tinning ability better, which is conducive to more stable welding of the PCB board and enhances the stability of signal transmission.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
