Technical Field

[0002] With the advancement of electronic technology, electronic devices such as mobile phones and computers are being used more and more frequently in people's daily lives, leading to increasingly higher requirements for their safety and performance. Connectors in electronic devices are used for charging and data transmission. Repeated plugging and unplugging can cause wear and tear on connectors, potentially leading to connector failure in severe cases.
[0003] To detect connector wear in a timely manner, the current practice is to add detection terminals to the connector to form a detection circuit. However, the addition of detection terminals increases the total number of terminals in the connector, requiring improvements to the connector, which is very costly, and it is incompatible with older electronic devices, resulting in high iteration costs.

[0034] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0035] Furthermore, the technical features involved in the 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 see Figures 1 to 3 This application provides a connector 100, which is applicable to electronic devices such as mobile phones, tablets, and laptops. The connector 100 is used for the transmission of electrical 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 a first direction X, where the first direction X can be understood as a direction perpendicular to the plane where the first side terminal group 10 is located, or as the thickness direction of the connector 100. The middle clamping plate assembly 30 is 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 realize the transmission of electrical energy and data. Of course, the connector 100 also includes an injection-molded 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 shell disposed outside the injection-molded part. This application does not limit the injection-molded part and the metal shell.
[0037] In some embodiments, please refer to Figure 3 and Figure 4The 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 is understood that the first terminal 11 and the third terminal 21 can be directly connected or indirectly connected. The first terminal 11 and the third terminal 21 are terminals that perform the same function, and they are centrally symmetrically arranged about the middle clamp assembly 30, so that when the connector 100 of this application is connected to an external connector 100, whether it is a right-side-out or left-side-out insertion, the terminals on the external connector 100 can remain connected to either the first terminal 11 or the third terminal 21.
[0038] The middle clamp assembly 30 includes a first middle clamp 31, which is electrically connected to the second terminal 12 to form a first detection circuit for detecting the performance of the second terminal 12. In some examples, the second terminal 12 is located at the outermost edge of the first side terminal group 10. During the use of the connector 100, the second terminal 12 is more susceptible to impact or wear than other terminals. Therefore, electrically connecting the first middle clamp 31 to the second terminal 12 to form a detection circuit allows for accurate and effective detection of the performance of the second terminal 12. For example, as... Figure 4 and Figure 5 As shown, when the second terminal 12 is subjected to impact or severe wear, the second terminal 12 will have poor contact with the first middle clamp 31 at position A. The first detection circuit will be open-circuited or the circuit parameters such as circuit resistance or voltage will change. That is, the abnormality of the second terminal 12 can be known by the change of the parameters of the first detection circuit, so as to remind the user to check or replace it.
[0039] The connectors 100 of existing electronic devices, such as the Type-C interface, need to meet the USB Association's standard requirements for connectors, such as having 24 terminals in the connector 100 to enable connection or plugging.
[0040] Compared to the existing technology where the first terminal 11 and the third terminal 21 are independently connected to the circuit, adding a detection circuit would result in at least one extra terminal, bringing the connector 100 to at least 25 terminals, which does not comply with the association's regulations. In this embodiment, the connector 100 connects the first terminal 11 and the third terminal 21, which perform the same function, so that they can be connected to the same circuit. The saved circuit can be used to connect the first middle clamp 31, allowing the first middle clamp 31 and the second terminal 12 to form the first detection circuit. This allows the connector 100 to maintain 24 terminals for connection to external connectors while still providing detection functionality, effectively solving the compatibility problem between connectors 100, improving compatibility, and reducing the cost of modification and iteration.
[0041] In some embodiments, a portion of the first terminal 11 and a portion of the third terminal 21 are directly connected to form an electrical connection. For example, they can be soldered together and then injection molded into a base, so that 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 also includes a circuit board 40, which has a first shorting circuit 41, a first functional circuit 42, and a second functional circuit 43. The first shorting circuit 41 is connected to the first terminal 11 and the third terminal 21 respectively, so that the first terminal 11 and the third terminal 21 are indirectly electrically connected. The first functional circuit 42 is electrically connected to the first intermediate clamping plate 31, and the second functional circuit 43 is electrically connected to the second terminal 12. In this way, the first functional circuit 42, the first intermediate clamping plate 31, the second terminal 12, and the second functional circuit 43 are connected in series. When the first functional circuit 42 and the second functional circuit 43 are connected to the detection circuit, 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, it is easier to connect the two by setting the first shorting circuit 41 on the circuit board 40, the structure is simpler, 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 makes it easier to inspect the circuit board 40. If the first terminal 11 and the third terminal 21 are directly connected and then encapsulated with injection molding, it will be difficult to repair.
[0043] In some embodiments, please refer to Figure 4 The circuit board 40 also includes a third functional circuit 44, which is electrically connected to the first shorting circuit 41, so that the third functional circuit 44 is electrically connected to the first terminal 11 and the third terminal 21. This structure allows one end of the third functional circuit 44 to be connected to both the first terminal 11 and the third terminal 21, and the other end of the third functional circuit 44 to be electrically connected to a terminal of the external connector 100. In other words, the first terminal 11 and the third terminal 21 are combined into a single input / output port, thereby reducing the number of functional circuits on the circuit board 40.
[0044] In some embodiments, please refer to Figure 3 and Figure 4The first terminal 11 includes a first main body portion 111 and a first welding portion 112 connected together, and the third terminal 21 includes a third main body portion 211 and a third welding portion 212 connected together. The first main body portion 111 and the third main body portion 211 are spaced apart in the first direction X and are centrally symmetrical about the middle clamping plate assembly 30, so that the connector 100 can be inserted into and out of the external connector 100. The first welding portion 112 and the third welding portion 212 are coplanar in a first plane (not shown), and the first plane is perpendicular to the first direction X (e.g., ...). Figure 2 As shown, the first welding part 112 and the third welding part 212 are spaced apart along the second direction Y, which is perpendicular to the first direction X. The first short-circuit circuit 41 electrically connects the first welding part 112 and the third welding part 212. By arranging the first welding part 112 and the third welding part 212 coplanarly in the first direction X, it is convenient to connect the first welding part 112 and the third welding part 212 to the first short-circuit welding connection of the circuit board 40.
[0045] In some embodiments, please refer to Figure 3 and Figure 4 The middle clamping plate assembly 30 also includes a second middle clamping plate 32, which is spaced apart from the first middle clamping plate 31 so that they are not directly connected. The second middle clamping plate 32 is electrically connected to the second functional circuit 43, which is grounded, thus grounding the second middle clamping plate 32 as well. The second middle clamping plate 32 and the first middle clamping plate 31 are positioned 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] The first intermediate clamp 31 and the second intermediate clamp 32 are spaced apart, allowing the current input from the first functional circuit 42 to flow sequentially through the first intermediate clamp 31 and the second terminal 12 before returning to the second functional circuit 43. This enables effective monitoring and detection of the second terminal 12. If the first intermediate clamp 31 and the second intermediate clamp 32 are directly connected, according to the current flow characteristics, the current input from the first functional circuit 42 will flow directly from the first intermediate clamp 31 to the second intermediate clamp 32 and then back to the second functional circuit 43, without passing through the second terminal 12, making it impossible to detect position A of the second terminal 12.
[0047] In some embodiments, please refer to Figure 3 and Figure 4The first intermediate plate 31 includes a first pin 311, which is connected to the first functional circuit 42. The second intermediate plate 32 includes a second pin 321, and the second terminal 12 includes a second main body 121 and a second welding part 122. One end of the second main body 121 is connected to the first intermediate plate 31, and the other end is connected to the second welding part 122. The first pin 311, the second pin 321, and the second welding part 122 are all located in a first plane, which facilitates their welding connection to the circuit board 40. The second welding part 122 and the second pin 321 are jointly connected to the second functional circuit 43, which can save on the functional circuits on the circuit board 40. It is understood that the second intermediate plate 32 can also be provided with multiple pins, all of which are grounded to further enhance the shielding performance of the first intermediate plate 31 and the second intermediate plate 32.
[0048] In some embodiments, please refer to Figure 3 and Figure 5 The second middle clamp 32 also includes a first contact portion 322, which bends and extends toward the second terminal 12. The first contact portion 322 is electrically connected to the second main body portion 121 of the second terminal 12, and can indirectly connect the first middle clamp 31 and the second middle clamp 32, so that the first middle clamp 31 is also grounded, further enhancing the shielding effect of the first middle clamp 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. In actual use, both corners of the connector 100 are prone to wear and impact. Therefore, to further improve the detection of the terminals at the two corners of the connector 100, the connector 100 in this embodiment can be provided with two detection circuits to detect the performance of the terminals at the two corners respectively. This allows for timely reminders to the user to replace the connector 100 when its performance deteriorates, ensuring the transmission of power 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 is understood that the fourth terminal 13 and the sixth terminal 22 can be directly or indirectly connected. The fourth terminal 13 and the sixth terminal 22 are terminals that perform the same function, and they are centrally symmetrically arranged about the middle clamp assembly 30, so that when the connector 100 of this application is connected to an external connector 100, whether it is a right-side-out or left-side-out insertion, the terminals on the external connector 100 can remain connected to the fourth terminal 13 or the sixth terminal 22.
[0051] The middle clamp assembly 30 includes a third middle clamp 33, which is spaced apart from the first middle clamp 31. The third middle clamp 33 is electrically connected to the fifth terminal 14 to form a second detection circuit for detecting the performance of the fifth terminal 14. In some examples, the fifth terminal 14 is located on the other outermost side of the first side terminal group 10, i.e., the second terminal 12 and the fifth terminal 14 are respectively located on the outermost side of the first side terminal group 10. During the use of the connector 100, the fifth terminal 14 is more susceptible to impact or wear than other terminals. Therefore, electrically connecting the third middle clamp 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 As shown, when the fifth terminal 14 is subjected to impact or severe wear, the fifth terminal 14 will have poor contact with the third middle clamp 33 at position B. The second detection circuit will be open-circuited or the circuit parameters such as circuit resistance or voltage will change. That is, the abnormality of the fifth terminal 14 can be detected by the change of the parameters of the second detection circuit, so as to remind the user to check or replace it.
[0052] Compared to the existing technology where the fourth terminal 13 and the sixth terminal 22 are independently connected to the circuit, adding a detection circuit would result in at least one extra terminal, bringing the connector 100 to at least 25 terminals, which does not comply with the association's regulations. In this embodiment, the connector 100 connects the fourth terminal 13 and the sixth terminal 22, which perform the same function, so that they can be connected to the same circuit. The saved circuit can be used to connect the third middle clamp 33, allowing the third middle clamp 33 and the fifth terminal 14 to form a second detection circuit. This allows the connector 100 to maintain 24 terminals for connection to external connectors while still providing detection functionality, effectively solving the compatibility problem between connectors 100, improving compatibility, and reducing the cost of modification and iteration.
[0053] In some embodiments, a portion of the fourth terminal 13 and a portion of the sixth terminal 22 are directly connected to form an electrical connection. For example, they can be soldered together and then injection molded into a base, so that 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 4The circuit board 40 is equipped with a second shorting circuit 45, a fourth functional circuit 46, and a fifth functional circuit 47. The second shorting circuit 45 is connected to the fourth terminal 13 and the sixth terminal 22 respectively, indirectly forming an electrical connection 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. When a detection circuit is connected between 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 where the fourth terminal 13 and the sixth terminal 22 are directly connected, it is easier to connect them by setting the second shorting circuit 45 on the circuit board 40, the structure is simpler, and the production difficulty is reduced. In addition, in later maintenance, the circuit board 40 can be separated from the fourth terminal 13 and the sixth terminal 22, which facilitates the inspection of the circuit board 40. If the fourth terminal 13 and the sixth terminal 22 are directly connected and then encased in injection molding, it would be difficult to repair.
[0055] In some embodiments, please refer to Figure 3 and Figure 4 The circuit board 40 also includes a sixth functional circuit 48, which is electrically connected to the second shorting circuit 45, so that the sixth functional circuit 48 is electrically connected to the fourth terminal 13 and the sixth terminal 22. This structure allows one end of the sixth functional circuit 48 to be connected to both the fourth terminal 13 and the sixth terminal 22, and the other end of the sixth functional circuit 48 to be electrically connected to a terminal of the external connector 100. In other words, the fourth terminal 13 and the sixth terminal 22 are combined into a single input / output port, thereby reducing the number of functional circuits on the circuit board 40.
[0056] In some embodiments, the fourth terminal 13 includes a fourth body portion 131 and a fourth welding portion 132 connected together, and the sixth terminal 22 includes a sixth body portion 221 and a sixth welding portion 222 connected together. The fourth body portion 131 and the sixth body portion 221 are spaced apart in the first direction X and are centrally symmetrical about the middle clamp assembly 30, so that the connector 100 can be inserted into and out of the external connector 100. The fourth welding portion 132 and the sixth welding portion 222 are coplanar in a first plane, which is perpendicular to the first direction X. The fourth welding portion 132 and the sixth welding portion 222 are spaced apart along a second direction Y, which is perpendicular to the first direction X. The second short-circuit circuit 45 is electrically connected to 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-circuited and welded to the circuit board 40.
[0057] In some embodiments, please refer to Figure 3 and Figure 4 The middle clamping plate assembly 30 also includes a fourth middle clamping plate 34, which is spaced apart from the third middle clamping plate 33 so that they are not directly connected. The fourth middle clamping plate 34 is electrically connected to the fifth functional circuit 47, which is grounded, thus grounding the fourth middle clamping plate 34 as well. The fourth middle clamping plate 34 and the third middle clamping plate 33 are positioned 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 and fourth intermediate plates 33 and 34 are spaced apart, allowing the current input from the fourth functional circuit 46 to flow sequentially through the third intermediate plate 33 and the fifth terminal 14 before returning to the fifth functional circuit 47. This enables effective monitoring and detection of the fifth terminal 14. If the third and fourth intermediate plates 33 and 34 are directly connected, according to the current flow characteristics, the current input from the fourth functional circuit 46 will flow directly from the third intermediate plate 33 to the fourth intermediate plate 34 and then back to the fifth functional circuit 47, bypassing the fifth terminal 14 and thus preventing detection of the fifth terminal 14.
[0059] In some embodiments, please refer to Figure 3 and Figure 4 The third intermediate plate 33 includes a third pin 331, which is connected to the fourth functional circuit 46. The fourth intermediate plate 34 includes a fourth pin 341. The fifth terminal 14 includes a fifth main body 141 and a fifth soldering part 142. One end of the fifth main body 141 is connected to the third intermediate plate 33, and the other end is connected to the fifth soldering part 142. The third pin 331, the fourth pin 341, and the fifth soldering part 142 are all located in the first plane, which facilitates soldering connections between them and the circuit board 40. The fifth soldering part 142 and the fourth pin 341 are jointly connected to the fifth functional circuit 47, which can save on the functional circuits on the circuit board 40. It is understood that the fourth intermediate plate 34 can also be provided with multiple pins, all of which are grounded to further enhance the shielding performance of the third intermediate plate 33 and the fourth intermediate plate 34.
[0060] In some embodiments, please refer to Figure 3 and Figure 5 The fourth middle clamp 34 also includes a second contact portion 342, which bends and extends toward the fifth terminal 14. The second contact portion 342 is electrically connected to the fifth main body portion 141 of the fifth terminal 14, and can indirectly connect the third middle clamp 33 and the fourth middle clamp 34, so that the third middle clamp 33 is also grounded, further enhancing the shielding effect of the third middle clamp 33 on the first side terminal group 10 and the second side terminal group 20.
[0061] In some embodiments, the first terminal 11 and the third terminal 21 are both first low-speed signal terminals; and / or, the fourth terminal 13 and the sixth terminal 22 are both second low-speed signal terminals. Since the first terminal 11, the third terminal 21, the fourth terminal 13, and the sixth terminal 22 are all used to transmit low-speed signals, the first terminal 11 and the third terminal 21 can share the same third functional circuit 44 to transmit signals with minimal impact on the signal. Similarly, the fourth terminal 13 and the sixth terminal 22 can share the same sixth functional circuit 48 to transmit signals with minimal impact on the signal.
[0062] In some embodiments, please refer to Figure 4 The circuit board 40 includes two shorting circuits and twenty-four functional circuits, all of which are coplanar. The circuit board 40 has opposing first end 401 and second end 402. The first end 401 is used to connect with the first side terminal group 10, the second side terminal group 20, and the middle clamping plate assembly 30, and has twenty-six connection areas. The second end 402 is used to connect with the external connector 100, and has twenty-four connection areas. Since the external connector 100 conforms to the association's specifications and has 24 terminal contact areas, the second end 402 of the circuit board 40 of the connector 100 in this application can perfectly connect with the external connector 100, exhibiting strong compatibility.
[0063] In some embodiments, please refer to Figure 4 The circuit board 40 also includes a first auxiliary circuit 4091 and a second auxiliary circuit 4092, which are coplanar with the twenty-four functional circuits. The first auxiliary circuit 4091 is soldered to the first soldering part 112 of the first terminal 11. A first shorting circuit 41 connects the first auxiliary circuit 4091 and the third functional circuit 44, facilitating the connection between the first shorting circuit 41 and the first terminal 11 and the third terminal 21. The second auxiliary circuit 4092 is soldered to the fourth soldering part 132 of the fourth terminal 13. A second shorting circuit 45 connects the second auxiliary circuit 4092 and the sixth functional circuit 48, facilitating the connection between the second shorting circuit 45 and the fourth terminal 13 and the sixth terminal 22. During manufacturing, the twenty-four functional circuits and two auxiliary circuits can be placed on the same layer, while the two shorting circuits are placed on another layer. The shorting circuits are electrically connected to their corresponding auxiliary and functional circuits via vias.
[0064] In some embodiments, the circuit board 40 of the connector 100 in this application is a rigid PCB circuit board 40. In other embodiments, the circuit board 40 is a flexible FPC circuit board 40. By using a flexible circuit board 40, the first end 401 and the second end 402 of the circuit board 40 can be at different horizontal levels, which greatly reduces the assembly and installation requirements between the connector 100 of this application and the external connector 100.
[0065] It is understood that in the above embodiments, a first detection circuit and a second detection circuit are respectively provided at the left and right ends of the first side terminal group 10 to detect the performance of the two outermost terminals at positions A and B. In other embodiments, one or two detection circuits may also be provided on the second side terminal group 20 to detect the performance of the terminals on the left and right sides of the second side terminal group 20. The specific configuration method can refer to the configuration method of the first detection circuit and the second detection circuit of the first side terminal group 10, which will not be repeated here.
[0066] This application also provides a connector module 200, please refer to... Figure 1 The connector module 200 includes a first fixing member 201, a single-row terminal group 202, a second fixing member 203, and the connector 100 in any of the above embodiments. The single-row terminal group 202 is disposed on the first fixing member 201, and the second end 402 of the circuit board 40 is connected to the single-row terminal group 202. The single-row terminal group 202 has 24 terminals arranged in a row. The 24 terminals of the single-row terminal group 202 are connected one-to-one with the 24 functional circuits of the second end 402 of the circuit board 40 to achieve the connection between the first side terminal group 10, the second side terminal group, the middle clamping plate assembly 30, and the single-row terminal group 202. The second fixing member 203 is connected to both the first fixing member 201 and the circuit board 40 to lock the second end 402 of the circuit board 40 to the first fixing member 201 and maintain it in contact with the single-row terminal group 202.
[0067] In some embodiments, after the single-row terminal group 202 is disposed on the first fixing member 201, it can be soldered to the motherboard assembly in the electronic device. At this time, the first fixing member 201 is fixed to the motherboard assembly, and the single-row terminal group 202 is electrically connected to the motherboard assembly. Then, the second end 402 of the circuit board 40 is mounted on the first fixing member 201, so that the circuit board 40 is correspondingly connected to the single-row terminal group 202. Then, the second fixing member 203 is connected to the first fixing member 201 to fix the circuit board 40.
[0068] As an example, the first fixing member 201 is provided with a first locking part 2011, and the second fixing member 203 is provided with a second locking part 2031. The first locking part 2011 and the second locking part 2031 are connected to each other, so that the first fixing member 201 is fixed relative to the second fixing member 203. More specifically, the first locking part 2011 and the second locking part 2031 can be connected in any way, such as snap-fit connection, locking connection, screw connection, etc.
[0069] The connector 100 of this application embodiment 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 includes at least a first terminal 11 and a second terminal 12. The second side terminal group 20 is spaced apart from the first side terminal group 10 along a first direction X, and the second side terminal group 20 includes at least a third terminal 21. The first terminal 11 and the third terminal 21 are electrically connected. The middle clamping plate assembly 30 is spaced apart between the first side terminal group 10 and the second side terminal group 20 along the first direction X. The middle clamping plate assembly 30 includes a first middle clamping plate 31, which 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. By electrically connecting the first terminal 11 and the third terminal 21, the connector 100 can effectively solve the problem of structural incompatibility between new and old connectors 100 while still having detection functionality.
