[0034] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not used to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0035] In addition, the technical features involved in different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0036] Please refer to Figures 1 to 3 , an embodiment of this application provides a connector 100, and the connector 100 can be applicable to electronic devices such as mobile phones, tablet computers, and laptop computers. The connector 100 is used for the transmission of electric energy and data. The connector 100 includes a first-side terminal group 10, a second-side terminal group 20, and a middle clamping plate assembly 30. The first-side terminal group 10 and the second-side terminal group 20 are spaced apart in the first direction X, where the first direction X can be understood as the direction perpendicular to the plane where the first-side terminal group 10 is located, or can also be understood as the thickness direction of the connector 100. The middle clamping plate assembly 30 is then spaced between the first-side terminal group 10 and the second-side terminal group 20. The first-side terminal group 10 and the second-side terminal group 20 are used to achieve the transmission of electric energy and data. Of course, the connector 100 also includes an injection molding part for supporting the first-side terminal group 10, the second-side terminal group 20, and the middle clamping plate assembly 30, and a metal housing disposed outside the injection molding part, and this application does not limit the injection molding part and the metal housing.

[0037] In some embodiments, please refer to Figure 3 and Figure 4, the first-side terminal group 10 includes at least a first terminal 11 and a second terminal 12. The second-side terminal group 20 includes at least a third terminal 21. The first terminal 11 and the third terminal 21 are connected. It can be understood that the first terminal 11 and the third terminal 21 can be directly connected or indirectly connected. Among them, the first terminal 11 and the third terminal 21 are terminals for realizing the same function, and they are centrally symmetrically arranged with respect to the middle splint assembly 30, so that when the connector 100 of the present application is connected to an external connector 100, whether it is inserted correctly or reversely, the terminals on the external connector 100 can maintain connection with the first terminal 11 or the third terminal 21.

[0038] The middle splint assembly 30 includes a first middle splint 31. The first middle splint 31 is electrically connected to the second terminal 12 to form a first detection circuit. The first detection circuit is used to detect the performance of the second terminal 12. In some examples, the second terminal 12 is located on the outermost side of the first-side terminal group 10. During the use of the connector 100, the second terminal 12 is more likely to be impacted or worn compared to other terminals. Therefore, electrically connecting the first middle splint 31 and the second terminal 12 to form a detection circuit can accurately and effectively detect the performance of the second terminal 12. For example, as Figure 4 and Figure 5 shown, when the second terminal 12 is severely impacted or worn, the second terminal 12 has poor contact with the first middle splint 31 at position A, the first detection circuit is open or circuit parameters such as circuit resistance or voltage change, that is, it can be known that the second terminal 12 is abnormal through the parameter change of the first detection circuit to remind the user to check or replace.

[0039] The connectors 100 of existing electronic devices, such as type-c interfaces, etc., need to meet the standard regulations of the USB Association regarding connectors. For example, there are 24 terminals in the connector 100 to achieve connection or plugging.

[0040] Compared with the structure in the prior art where the first terminal 11 and the third terminal 21 are independently connected to the circuit respectively, then in the case of adding a detection circuit, at least one more terminal will be caused, and the number of terminals in the connector 100 becomes at least 25, which does not meet the regulations of the association. In the connector 100 of the embodiment of the present application, the first terminal 11 and the third terminal 21 that realize the same function are connected so as to connect the two to the same circuit, and the other circuit saved can be used for the first middle splint 31 to be connected, so that the first middle splint 31 and the second terminal 12 can form a first detection circuit, so that the connector 100 can still maintain 24 terminals to realize plugging with the external connector 100 on the basis of having a detection function, effectively solving the adaptation problem between the connectors 100, improving compatibility, and additionally reducing the cost of modification and iteration.

[0041] In some embodiments, a part of the first terminal 11 and a part of the third terminal 21 are directly connected so that they form an electrical connection. For example, after welding them together, plastic injection molding is performed to form a base. In this way, only one of the first terminal 11 and the third terminal 21 needs to be electrically connected to the circuit board 40 described below.

[0042] In other embodiments, please refer to Figure 1 and Figure 4 , the connector 100 further includes a circuit board 40. The circuit board 40 is provided with a first short - circuit circuit 41, a first functional circuit 42, and a second functional circuit 43. The first short - circuit circuit 41 is respectively connected to the first terminal 11 and the third terminal 21, enabling the first terminal 11 and the third terminal 21 to indirectly form an electrical connection. The first functional circuit 42 is connected to the first middle clamping plate 31, and the second functional circuit 43 is connected to the second terminal 12. In this way, the first functional circuit 42, the first middle clamping plate 31, the second terminal 12, and the second functional circuit 43 are connected in series in sequence. When a detection circuit is connected to the first functional circuit 42 and the second functional circuit 43, a closed loop can be formed to detect the performance of the second terminal 12. Compared with the structure in which the first terminal 11 and the third terminal 21 are directly connected, the difficulty of setting the first short - circuit circuit 41 on the circuit board 40 to connect them is lower, the structure is simple, and the production difficulty is reduced. In addition, during later maintenance, the circuit board 40 can be separated from the first terminal 11 and the third terminal 21, which is convenient for repairing the circuit board 40. If the first terminal 11 and the third terminal 21 are directly connected and then injection - molded and wrapped, it is difficult to repair.

[0043] In some embodiments, please refer to Figure 4 , the circuit board 40 further includes a third functional circuit 44. The third functional circuit 44 is electrically connected to the first short - circuit circuit 41 so that the third functional circuit 44 is electrically connected to the first terminal 11 and the third terminal 21. Such a structure can enable one end of the third functional circuit 44 to be commonly connected to the first terminal 11 and the third terminal 21, and the other end of the third functional circuit 44 to be connected to a terminal of the external connector 100. That is, the two terminals of the first terminal 11 and the third terminal 21 are aggregated into an input / output port to save the number of functional circuits on the circuit board 40.

[0044] In some embodiments, please refer to Figure 3 and Figure 4, the first terminal 11 includes a connected first main body portion 111 and a first welding portion 112, and the third terminal 21 includes a connected third main body portion 211 and a third welding portion 212. The first main body portion 111 and the third main body portion 211 are spaced apart in the first direction X and are centrally symmetrically arranged with respect to the middle splint assembly 30, so that the connector 100 can be inserted into and reverse-inserted with an external connector 100. The first welding portion 112 and the third welding portion 212 are coplanar in a first plane (not shown in the figure), the first plane is perpendicular to the first direction X (as Figure 2 shown), the first welding portion 112 and the third welding portion 212 are spaced apart in a second direction Y, the second direction Y is perpendicular to the first direction X, and the first short-circuit circuit 41 electrically connects the first welding portion 112 and the third welding portion 212. By arranging the first welding portion 112 and the third welding portion 212 coplanarly in the first direction X, it is convenient for the first welding portion 112 and the third welding portion 212 to be short-circuit welded to the circuit board 40 by the first short-circuit.

[0045] In some embodiments, please refer to Figure 3 and Figure 4 , the middle splint assembly 30 further includes a second middle splint 32, and the second middle splint 32 and the first middle splint 31 are spaced apart so that they are not directly connected. The second middle splint 32 is electrically connected to the second functional circuit 43, and the second functional circuit 43 is grounded, so that the second middle splint 32 is also grounded. The second middle splint 32 and the first middle splint 31 are arranged between the first side terminal group 10 and the second side terminal group 20, which can enhance the shielding effect and reduce the mutual interference between the first side terminal group 10 and the second side terminal group 20.

[0046] And the first middle splint 31 and the second middle splint 32 are spaced apart, so that the current input from the first functional circuit 42 can flow back to the second functional circuit 43 after passing through the first middle splint 31 and the second terminal 12 in sequence. In this way, the second terminal 12 can be effectively monitored and detected. If the first middle splint 31 and the second middle splint 32 are directly connected, according to the current flow characteristics, the current input from the first functional circuit 42 directly flows to the second middle splint 32 and flows back to the second functional circuit 43 after flowing into the first middle splint 31, and it does not pass through the second terminal 12, and the position A of the second terminal 12 cannot be detected.

[0047] In some embodiments, please refer to Figure 3 and Figure 4, the first middle splint 31 includes a first pin 311, and the first pin 311 is connected to the first functional circuit 42. The second middle splint 32 includes a second pin 321. The second terminal 12 includes a second main body portion 121 and a second welding portion 122. One end of the second main body portion 121 is connected to the first middle splint 31, and the other end of the second main body portion 121 is connected to the second welding portion 122. The first pin 311, the second pin 321, and the second welding portion 122 are all located in the first plane, which facilitates the welding connection of the three with the circuit board 40. The second welding portion 122 and the second pin 321 are jointly connected to the second functional circuit 43, which can save the functional circuits on the circuit board 40. It can be understood that the second middle splint 32 can also be provided with multiple pins, and the multiple pins are all grounded to further enhance the shielding performance of the first middle splint 31 and the second middle splint 32.

[0048] In some embodiments, please refer to Figure 3 and Figure 5 , the second middle splint 32 further includes a first contact portion 322. The first contact portion 322 extends bent towards the second terminal 12. The first contact portion 322 is electrically connected to the second main body portion 121 of the second terminal 12, which can indirectly connect the first middle splint 31 and the second middle splint 32, so that the first middle splint 31 is also grounded, further enhancing the shielding effect of the first middle splint 31 on the first side terminal group 10 and the second side terminal group 20.

[0049] In the above embodiments, the connector 100 is provided with a detection circuit to detect the second terminal 12. During actual use, both corners of the connector 100 are vulnerable to wear and impact. Therefore, in order to further improve the detection of the terminals at the two corners of the connector 100, the connector 100 in the embodiment of the present application can be provided with two detection circuits to respectively detect the performance of the terminals at the two corners, so as to timely remind the user to replace the connector 100 when the performance of the connector 100 decays, ensuring the transmission of electric energy and signals.

[0050] In some embodiments, please refer to Figures 1 to 3 , the first side terminal group 10 includes at least a fourth terminal 13 and a fifth terminal 14. The second side terminal group 20 includes at least a sixth terminal 22. The fourth terminal 13 and the sixth terminal 22 are connected. It can be understood that the fourth terminal 13 and the sixth terminal 22 can be directly connected or indirectly connected. Among them, the fourth terminal 13 and the sixth terminal 22 are terminals for realizing the same function, and the two are symmetrically arranged about the middle splint assembly 30, so that when the connector 100 of the present application is connected to an external connector 100, whether it is inserted forward or backward, the terminals on the external connector 100 can maintain connection with the fourth terminal 13 or the sixth terminal 22.

[0051] The middle splint assembly 30 includes a third middle splint 33, and the third middle splint 33 is arranged at an interval from the first middle splint 31. The third middle splint 33 is electrically connected to the fifth terminal 14 to form a second detection circuit, and the second detection circuit is used to detect the performance of the fifth terminal 14. In some examples, the fifth terminal 14 is located at the other outermost side of the first side terminal group 10, that is, the second terminal 12 and the fifth terminal 14 are respectively located at the outermost sides of the first side terminal group 10. During the use of the connector 100, the fifth terminal 14 is more likely to be impacted or worn compared with other terminals. Therefore, electrically connecting the third middle splint 33 to the fifth terminal 14 to form a detection circuit can accurately and effectively detect the performance of the fifth terminal 14. For example, as Figure 4 and Figure 5 shown, when the fifth terminal 14 is severely impacted or worn, the fifth terminal 14 has poor contact with the third middle splint 33 at position B, the second detection circuit is open or circuit parameters such as circuit resistance or voltage change, that is, it can be known that the fifth terminal 14 is abnormal through the parameter change of the second detection circuit to remind the user to check or replace.

[0052] Compared with the structure in the prior art where the fourth terminal 13 and the sixth terminal 22 are respectively independently connected to the circuit, then in the case of adding a detection circuit, at least one more terminal will be caused, and the number of terminals in the connector 100 will become at least 25, which does not meet the regulations of the association. In the connector 100 according to the embodiment of the present application, the fourth terminal 13 and the sixth terminal 22 that perform the same function are connected so as to connect the two to the same circuit, and the other circuit saved can be used for the third middle splint 33 to be connected, so that the third middle splint 33 and the fifth terminal 14 can form a second detection circuit, so that the connector 100 can still have 24 terminals to be plugged with the external connector 100 on the basis of having a detection function, effectively solving the adaptation problem between the connectors 100, improving compatibility, and additionally reducing the cost of modification and iteration.

[0053] In some embodiments, a part of the fourth terminal 13 and a part of the sixth terminal 22 are directly connected so that the two are electrically connected. For example, after welding the two and then performing plastic injection molding to form a base, only one of the fourth terminal 13 and the sixth terminal 22 needs to be electrically connected to the circuit board 40.

[0054] In other embodiments, please refer to Figure 3 and Figure 4, the circuit board 40 is provided with a second short - circuit circuit 45, a fourth functional circuit 46, and a fifth functional circuit 47. The second short - circuit circuit 45 is respectively connected to the fourth terminal 13 and the sixth terminal 22, so that an electrical connection is indirectly formed between the fourth terminal 13 and the sixth terminal 22. The fourth functional circuit 46 is electrically connected to the third middle clamping plate 33, and the fifth functional circuit 47 is electrically connected to the fifth terminal 14. In this way, the fourth functional circuit 46, the third middle clamping plate 33, the fifth terminal 14, and the fifth functional circuit 47 are connected in series in sequence. When a detection circuit is connected to the fourth functional circuit 46 and the fifth functional circuit 47, a closed loop can be formed to detect the performance of the fifth terminal 14. Compared with the structure in which the fourth terminal 13 and the sixth terminal 22 are directly connected, setting the second short - circuit circuit 45 on the circuit board 40 to connect the two has lower difficulty, with a simple structure, reducing the production difficulty. In addition, during later maintenance, the circuit board 40 can be separated from the fourth terminal 13 and the sixth terminal 22, facilitating the repair of the circuit board 40. If the fourth terminal 13 and the sixth terminal 22 are directly connected and then injection - molded and wrapped, it is difficult to repair.

[0055] In some embodiments, please refer to Figure 3 and Figure 4 , the circuit board 40 further includes a sixth functional circuit 48, and the sixth functional circuit 48 is electrically connected to the second short - circuit circuit 45, so that the sixth functional circuit 48 is electrically connected to the fourth terminal 13 and the sixth terminal 22. Such a structure can enable one end of the sixth functional circuit 48 to be commonly connected to the fourth terminal 13 and the sixth terminal 22, and the other end of the sixth functional circuit 48 is electrically connected to a terminal of the external connector 100, that is, the fourth terminal 13 and the sixth terminal 22 are integrated into an input / output port, so as to save the number of functional circuits on the circuit board 40.

[0056] In some embodiments, the fourth terminal 13 includes a connected fourth main body portion 131 and a fourth welding portion 132, and the sixth terminal 22 includes a connected sixth main body portion 221 and a sixth welding portion 222. The fourth main body portion 131 and the sixth main body portion 221 are spaced apart in the first direction X and are centrosymmetrically arranged with respect to the middle clamping plate assembly 30, so as to facilitate the connector 100 to be inserted correctly and reversely with the external connector 100. The fourth welding portion 132 and the sixth welding portion 222 are coplanar in the first plane, the first plane is perpendicular to the first direction X, the fourth welding portion 132 and the sixth welding portion 222 are spaced apart in the second direction Y, the second direction Y is perpendicular to the first direction X, and the second short - circuit circuit 45 electrically connects the fourth welding portion 132 and the sixth welding portion 222. By arranging the fourth welding portion 132 and the sixth welding portion 222 coplanar in the first direction X, it is convenient for the fourth welding portion 132 and the sixth welding portion 222 to be short - circuit welded to the first short - circuit of the circuit board 40.

[0057] In some embodiments, please refer toFigure 3 and Figure 4 The middle splint assembly 30 further includes a fourth middle splint 34. The fourth middle splint 34 and the third middle splint 33 are arranged at intervals so that they are not directly connected. The fourth middle splint 34 is electrically connected to the fifth functional circuit 47, and the fifth functional circuit 47 is grounded, so that the fourth middle splint 34 is also grounded. The fourth middle splint 34 and the third middle splint 33 are arranged between the first side terminal group 10 and the second side terminal group 20, which can enhance the shielding effect and reduce the mutual interference between the first side terminal group 10 and the second side terminal group 20.

[0058] The third middle splint 33 and the fourth middle splint 34 are arranged at intervals, so that the current input from the fourth functional circuit 46 can flow back to the fifth functional circuit 47 after passing through the third middle splint 33 and the fifth terminal 14 in sequence. In this way, the fifth terminal 14 can be effectively monitored and detected. If the third middle splint 33 and the fourth middle splint 34 are directly connected, according to the current flow characteristics, the current input from the fourth functional circuit 46 flows directly to the fourth middle splint 34 after flowing into the third middle splint 33 and flows back to the fifth functional circuit 47 without passing through the fifth terminal 14, and the fifth terminal 14 cannot be detected.
