Description

[Technical Field]

[0001] The present application relates to the field of electronic devices, and in particular to connectors and electronic devices provided with connectors. [Background technology]

[0002] A connector is a device that connects electrical terminals to form a circuit. Connectors can be used to implement connections between wires, cables, printed circuit boards, and electrical components, and can transmit data, power, and signals. Connectors typically use metal shielding sheets or conductive plastics to prevent signal current reference return and isolate signal crosstalk. However, the conductivity of conductive plastics is relatively low, making their effectiveness in preventing signal crosstalk poor for high-speed connectors. Metal shielding sheets implement signal current reference return using a suspended grounding method. However, the suspended grounding structure is usually an open circuit, which can cause crosstalk resonance due to low-frequency signals, resulting in crosstalk when the transmission speed is 28 Gb / s or higher. Summary of the Invention

[0003] The present application aims to provide a connector for improving the anti-crosstalk capability of the connector by improving the suspended ground structure. In addition, the present application further relates to an electronic device provided with the connector.

[0004] According to a first aspect, the present application relates to a connector including a plurality of transmission lines and at least one shielding sheet, wherein an extension direction of each transmission line intersects a first direction, and the plurality of transmission lines include at least one ground pin; the shielding sheet is conductive, and includes a main body portion, at least one first support leg, and at least one second support leg, the main body portion extends along the first direction and spans the plurality of transmission lines from one side of the plurality of transmission lines to the other side of the plurality of transmission lines, the first support leg and the second support leg are respectively disposed on both sides of the main body portion, the first support leg is fixed to the ground pin, and the second support leg is also fixed to the ground pin, and the main body portion is spaced apart from the plurality of transmission lines.

[0005] In the present application, the connector implements signal transmission by using multiple parallel transmission lines arranged at intervals, and at least one ground pin is disposed within the multiple transmission lines to provide a ground potential for the transmitted signal. In the present application, the connector further prevents signal crosstalk by using a shielding sheet disposed therein. The shielding sheet is electrically connected to the ground pin via first and second support legs disposed on both sides of the main body, respectively, so that an electrical path passing through the main body can be formed for the ground pin. In the process of signal transmission through the multiple transmission lines, the electrical path passing through the main body can effectively prevent the reference feedback phenomenon of the signal current, thereby avoiding the influence of crosstalk resonance of low-frequency signals to improve the integrity of the signal transmission of the connector.

[0006] In a possible implementation, the number of the first support legs, the number of the second support legs, and the number of the ground pins are the same, and each ground pin is electrically connected to one first support leg and one second support leg.

[0007] In this implementation, the first support leg and the second support leg, respectively arranged on both sides of the main body portion, are electrically connected to the same ground pin, thereby enabling the electrical length of each ground pin to be shortened for implementing current return in the shielding sheet, thereby reducing the inductance effect formed by the shielding sheet for each ground pin.

[0008] In a possible implementation, the first support leg and the second support leg are each disposed parallel to the extension direction of the transmission line.

[0009] In this implementation, the first support leg is arranged parallel to the extension direction of the transmission line, i.e., the first support leg is arranged parallel to the ground pin electrically connected to the first support leg, thereby reducing the length of the first support leg, which helps to reduce the inductance effect formed by the shielding sheet with respect to the ground pin, and the second support leg is also arranged parallel to the extension direction of the transmission line, thereby reducing the length of the second support leg, which also reduces the inductance effect formed by the shielding sheet with respect to the ground pin.

[0010] In a possible implementation, the multiple transmission lines all extend along a second direction, the second direction being perpendicular to the first direction.

[0011] In this implementation, since the main body spans multiple transmission lines, when the length direction of the main body is perpendicular to the extension direction of the multiple transmission lines, the length of the main body is minimized, and the inductance effect formed on each transmission line is correspondingly reduced.

[0012] In a possible implementation, the plurality of transmission lines further includes a plurality of signal pins, and the at least one ground pin includes two side ground pins, the two side ground pins being spaced apart, and all of the plurality of signal pins being located between the two side ground pins.

[0013] In this embodiment, a structure of two side ground pins is provided, and the two side ground pins are respectively disposed at the outermost edges of multiple transmission lines arranged in parallel, thereby effectively shielding signal crosstalk on both sides of the multiple transmission lines, thereby ensuring the integrity of signals transmitted through signal pins positioned between the two side ground pins.

[0014] In a possible implementation, the at least one ground pin further includes a plurality of intermediate ground pins, the plurality of intermediate ground pins being spaced apart among the plurality of signal pins, and the at least one signal pin being disposed between any two adjacent ground pins.

[0015] In this implementation, the provision of multiple intermediate ground pins can prevent the signal crosstalk phenomenon between adjacent signal pins, thereby further ensuring the integrity of the signals transmitted through each signal pin.

[0016] In a possible implementation, the number of signal pins between any two adjacent ground pins is the same.

[0017] In this embodiment, the number of signal pins between every two adjacent ground pins is set to be the same, that is, the ground pins are evenly spaced on the transmission lines, so that the number of signal pins that each ground pin shields from signal crosstalk is also the same, thereby ensuring the quality of the signals transmitted through each signal pin is the same.

[0018] In possible implementations, there are one or two signal pins between any two adjacent ground pins.

[0019] In this embodiment, there is one signal pin between two adjacent ground pins, and shielding can be implemented for each signal pin by using two ground pins on both sides of the signal pin, and its signal transmission quality is relatively high; when there are two signal pins between two adjacent ground pins, the two signal pins can cooperate to form differential signal transmission, and its anti-interference ability is stronger.

[0020] In a possible implementation, a plurality of first current points are formed between the first support leg and the ground pin, and the plurality of first current points are spaced apart along the extension direction of the ground pin; and / or a plurality of second current points are formed between the second support leg and the ground pin, and the plurality of second current points are spaced apart along the extension direction of the ground pin.

[0021] In this embodiment, a plurality of first current-carrying points are arranged to improve the reliability of electrical conduction between the first support leg and the ground pin and form a shunt function for the ground pin. Correspondingly, a plurality of second current-carrying points are arranged to improve the reliability of electrical conduction between the second support leg and the ground pin and also form a shunt function for the ground pin.

[0022] In a possible implementation, there are multiple shielding sheets, the multiple shielding sheets being spaced apart along the extension direction of the transmission line.

[0023] In this implementation, multiple shielding sheets are spaced apart along the extension direction of the transmission line, thereby forming a larger area of ​​shielding protection effect in the extension direction of the transmission line, reducing the length requirement of a single shielding sheet, and thereby helping to reduce the inductance effect that a single shielding sheet may cause on the transmission line.

[0024] In a possible implementation, the main bodies of the shielding sheets are electrically connected to one another.

[0025] In this implementation, the main body portions of the multiple shielding sheets are electrically connected to each other, so that the multiple shielding sheets are connected to each other to form multiple electrical paths, which further prevents the occurrence of reference feedback phenomenon of signal current and avoids crosstalk resonance of low-frequency signals.

[0026] In a possible implementation, the shielding sheet further includes a third support leg, which is positioned between the first support leg and the second support leg and is also connected to the main body portion, and the third support leg is also electrically connected to the ground pin.

[0027] In this implementation, the third support leg is positioned between the first support leg and the second support leg, thereby reducing the length of the electrical path between the first current point and the second current point, thereby further reducing the inductance effect that may be caused by the shielding sheet.

[0028] In a possible implementation, the connector includes an insulating base, and the plurality of transmission lines and the main body portion of the shielding sheet are separately fixedly connected to the insulating base, so that the main body portion and the plurality of transmission lines are fixed at a distance from each other.

[0029] In this embodiment, the transmission lines and the shielding sheet are supported by an insulating base to ensure a positional relationship between the transmission lines and the shielding sheet without affecting the implementation of the electrical function of the connector.

[0030] In a possible implementation, the insulating base includes an insulating substrate, the plurality of transmission lines are printed on the insulating substrate, and the shielding sheet is positioned on a side of the plurality of transmission lines facing away from the insulating substrate.

[0031] In this implementation, the method of printing multiple transmission lines on the insulating substrate makes manufacturing easier, and disposing the shielding sheet on the outside of the insulating substrate makes manufacturing and assembly of the shielding sheet easier.

[0032] In a possible implementation, the insulating base includes an insulating substrate, the plurality of transmission lines are printed on the insulating substrate, and the shielding sheet is positioned inside the insulating substrate.

[0033] In this implementation, the shielding sheet is embedded in the insulating substrate, so that the relative positions of the shielding sheet and the multiple transmission lines can be ensured.

[0034] According to a second aspect, the present application relates to an electronic device comprising two functional components and a connector as described above connected between the two functional components.

[0035] It can be understood that since the electronic device of the present application is provided with the aforementioned connector, the signal transmission speed between two functional components in the electronic device of the present application is higher, and the signal integrity and reliability are also ensured.

[0055] Please refer to an example in FIG. 1 , which illustrates an internal structure of an electronic device 200 according to an embodiment of the present application. The electronic device 200 in the present application includes a first functional component 201 and a second functional component 202. A first chip 201A is disposed on the first functional component 201, and a second chip 202B is disposed on the second functional component 202. In the example of FIG. 1 , the first functional component 201 and the second functional component 202 are both circuit boards, and the first chip 201A and the second chip 202B are respectively connected to the circuit boards. In addition, a connector 100 in the present application is further disposed between the first functional component 201 and the second functional component 202. The connector 100 in the present application is connected between the first functional component 201 and the second functional component 202 and configured to implement signal transmission between the first chip 201A and the second chip 202B.

[0056] In some other embodiments, the electronic device 200 provided herein may further include more functional components, and the connector 100 herein may also be disposed between the multiple functional components to implement signal transmission between any two functional components by using the connector 100. In addition, in some embodiments, more chips may be further disposed on the first functional component 201, and the multiple chips may also implement signal transmission with the second chip 202B on the second functional component 202 by using the connector 100; or multiple chips may be disposed on the second functional component 202, and the multiple chips may also implement the function of signal transmission with the first chip 201A on the first functional component 201 by using the connector 100.

[0057] When mounted on the electronic device 200 of the present application, the connector 100 of the present application is configured to implement various functions of the electronic device 200. The electronic device 200 of the present application may be any device with communication, computing, or storage capabilities, such as an intelligent device such as a tablet computer, a mobile phone, an e-reader, a remote control, a personal computer (PC), a notebook computer, an in-car device, a network television, a smart appliance, or a wearable device.

[0058] In the example of FIG. 1 , the connector 100 includes a first connecting end 101, a second connecting end 102, and a data transmission segment 103 connected between the first connecting end 101 and the second connecting end 102. The first connecting end 101 and the first functional component 201 are fixedly connected and electrically connected to transmit signals. The second connecting end 102 and the second functional component 202 are fixedly connected and electrically connected to transmit signals. The first connecting end 101 and the first functional component 201 may be fixedly and electrically connected to each other by methods such as welding, spring pressing, pin plugging, or back connector crimping. The second connecting end 102 and the second functional component 202 may also be fixedly and electrically connected to each other by the aforementioned methods. In the example shown in FIG. 1 , the data transmission segment 103 is connected between the first connecting end 101 and the second connecting end 102 by using a flexible flat cable structure. The flexible flat cable has the characteristic of being flexible and can bend adaptively in accordance with the relative positions of the first functional component 201 and the second functional component 202, thereby facilitating the arrangement of the first functional component 201 and the second functional component 202 in the electronic device 200 of the present application.

[0059] See an example in FIG. 2 , which shows a connection between the second connecting end 102 and the second functional component 202 of the connector 100 of the present application. The connector 100 includes a housing 30, a plurality of transmission lines 10, and a shielding sheet 20 at the second connecting end 102. The housing 30 is made of an insulating material and is also understood as an insulating substrate in the connector 100. In the example of FIG. 2 , the housing 30 is a cubic structure, and the housing 30 is fixedly connected to the second functional component 202 to implement a fixed connection between the second connecting end 102 and the second functional component 202. In some other embodiments, the insulating substrate may alternatively be implemented by using a flat structure such as an insulating substrate 33 (see FIG. 13 ).

[0060] The multiple transmission lines 10 are fixedly connected to the housing 30, i.e., the housing 30 is configured to hold the multiple transmission lines 10. The multiple transmission lines 10 are arranged parallel to each other, and any two transmission lines 10 are spaced apart. The multiple transmission lines 10 extend in the same direction (this is the second direction 002 shown in the figure). See the partial structure shown as an example in FIG. 3. In this embodiment of the present application, the extension path of a single transmission line 10 actually bends twice. In other words, a bent portion 13 is formed on the extension path of each transmission line 10. In the parallel extension process of the multiple transmission lines 10, the distance, bend radius, bend angle, etc. of the bent portions 13 of the multiple transmission lines 10 are the same, and after bending, the transmission lines 10 are still parallel to each other and extend side by side in the same direction. Therefore, whether the transmission lines 10 are bent, i.e., whether the transmission lines 10 have bent portions 13, does not affect the restriction defined in this application that the multiple transmission lines 10 extend in the same direction. In other words, at any position on the extension path of the transmission lines 10, the multiple transmission lines 10 are in an orientation that extends in the same direction.

[0061] 3 , the transmission lines 10 are used as a structure for implementing signal transmission in the connector 100 of the present application. When connected to the second functional component 202, the transmission lines 10 are each electrically connected to a contact point 2021 of the second functional component 202. In the example of FIG. 3 , each contact point 2021 is constructed as a land structure, and the transmission lines 10 are each connected to the contact point 2021 by welding. It can be understood that in other embodiments, the contact points 2021 and the transmission lines 10 may be electrically connected to each other in other ways. The other end of the transmission lines 10 is electrically connected to the data transmission segment 103 of the connector 100. The second connection end 102 transfers the electrical signals in the data transmission segment 103 to the second functional component 202 via the multiple transmission lines 10.

[0062] 4 shows an example of the structure of the second connection end 102 of the connector 100 of the present application, and FIG. 5 shows an example of an exploded view of the structure of the second connection end 102. The multiple transmission lines 10 of the present application further include at least one ground pin 11 and multiple signal pins 12. The signal pin 12 is configured to transmit a data signal, and the ground pin 11 provides a ground potential required to transmit the data signal at the signal pin 12. After separately receiving the data transmitted via the ground pin 11 and the data transmitted via the signal pin 12, the second functional component 202 may compare the electrical signal at the signal pin 12 with the ground potential at the ground pin 11 to obtain the electrical signal data transmitted by the first functional component 201. Alternatively, when transmitting data to the first functional component 201, the second functional component 202 simultaneously applies a ground potential to the ground pin 11 and a data signal to the signal pin 12. After simultaneously receiving the data on the ground pin 11 and the data on the signal pin 12, the first functional component 201 may obtain the electrical signal data transmitted by the second functional component 202 in a similar manner. The provision of the ground pin 11 can shield the crosstalk problem caused by surrounding signals, so that the signals transmitted in the connector 100 have higher quality and higher integrity.

[0063] The shielding sheet 20 of the present application is configured to mainly shield signal crosstalk that may be generated by signals in the surrounding environment of the transmission line 10. Specifically, referring to FIG. 6 , the shielding sheet 20 includes a main body portion 23, a first support leg 21, and a second support leg 22. The main body portion 23 is roughly in the shape of a long strip and has opposing first and second side edges 231 and 232. The first support leg 21 and the second support leg 22 are respectively disposed on either side of the main body portion 23. The first support leg 21 is positioned closer to the first side edge 231 and extends from the first side edge 231 in a direction away from the main body portion 23. In this case, the first support leg 21 is connected to the main body portion 23. The second support leg 22 is positioned closer to the second side edge 232, and extends from the second side edge 232 in a direction away from the main body portion 23. In this case, the second support leg 22 is also connected to the main body portion 23.

[0064] The main body 23 is spaced apart from the transmission lines 10 and fixed to the housing 30. The main body 23 further spans the multiple transmission lines 10 along the first direction 001. Specifically, the main body 23 further includes a first end 233 and a second end 234. The first end 233 and the second end 234 are respectively positioned on opposite sides of the main body 23 along the length direction of the main body 23 (i.e., the first direction 001). In a direction in which the multiple transmission lines 10 are arranged side by side, the first end 233 is positioned on one side of the multiple transmission lines 10, and the second end 234 is positioned on the other side of the multiple transmission lines 10. In this manner, the main body 10 can be arranged across the transmission lines 10.

[0065] 4 and 5, the housing 30 is provided with a first clamp slot 31 and a second clamp slot 32, and a first clamp leg 2331 and a second clamp leg 2341 are provided at the first end 233 and the second end 234, respectively. The first clamp slot 31 is disposed corresponding to the first clamp leg 2331 and is configured to receive and secure the first clamp leg 2331. The second clamp slot 32 is disposed corresponding to the second clamp leg 2341 and is configured to receive and secure the second clamp leg 2341. In this manner, the shielding sheet 20 is fixed to the housing 30 and extends over the transmission line 10. It should be noted that the structures of the first clamp leg 2331 and the second clamp leg 2341 are provided merely as an example. The specific connection method between the main body 23 and the housing 30 is not limited to the connector 100 of the present application. In some other embodiments, the body portion 23 may alternatively be fixedly connected to the housing 30 in any manner, such as by bolting or integral injection molding.

[0066] Referring to the example of FIG. 5 , in one embodiment shown in the figure, the body portion 23 is fixed corresponding to the bending portions 13 of the multiple transmission lines 10. Therefore, the shape of the body portion 23 also bends along with the angle change of the transmission lines 10. Therefore, the first side edge 231 and the second side edge 232 are formed in different directions on the side wall of the body portion 23. In this case, the fact that the first side edge 231 and the second side edge 232 are disposed opposite each other may be understood as the two side edges bending and deforming together with the body portion 23, or may be understood as the first side edge 231 and the second side edge 232 being disposed opposite each other along the bending path of the transmission line 10. In some other embodiments, when the transmission line 10 has a planar structure (see FIG. 13 ), it may be understood that the body portion 23 does not need to bend or deform. In this case, the first side edge 231 and the second side edge 232 are disposed opposite each other in the same direction.

[0067] From the first side edge 231, the first support leg 21 extends away from the main body 23. A first conductive end 211 is present on the first support leg 21 at a position facing away from the main body 23. The first support leg 21 extends toward and is electrically connected to one ground pin 11 of the multiple transmission lines 10. The first support leg 21 may be electrically connected to the ground pin 11 by methods such as welding or pressing. For details, see an example in FIG. 7. The first support leg 21 and the ground pin 11 form at least one first current-carrying point 111. The first current-carrying point 111 is further located on a side of the first side edge 231 facing away from the second side edge 232.

[0068] From the second side edge 232, the second support leg 22 extends away from the main body 23. A second conductive end 221 is located on the second support leg 22 at a position facing away from the main body 23. The second support leg 22 also extends toward one ground pin 11 and is electrically connected to the ground pin 11. The second support leg 22 may also be electrically connected to the ground pin 11 by welding, pressing, or another method. Specifically, the second support leg 22 and the ground pin 11 form at least one second current-carrying point 112. The second current-carrying point 112 is further located on a side of the first side edge 231 facing away from the second side edge 232.

[0069] In some embodiments, the number of first support legs 21 is the same as the number of second support legs 22. In addition, each second support leg 12 is arranged to correspond to the position of one first support leg 11. That is, the first support legs 21 and the second support legs 22, which are positioned corresponding to each other, are arranged symmetrically with respect to the main body 23. In addition, the number of first support legs 21 is also the same as the number of ground pins 11 in the multiple transmission lines 10. The first support legs 21 and the second support legs 22, which are positioned corresponding to each other, are electrically connected to the same ground pin 11. It may be understood that in some other embodiments, the numbers of first support legs 21, second support legs 22, and ground pins 11 may alternatively be different. If each of the multiple ground pins 11 is connected using the first support legs 21 and the second support legs 22, and an electrical path connected to opposite sides of the main body is formed, the effect of the solution of the connector 100 of the present application can also be implemented.

[0070] The shielding sheet 20 is electrically conductive. The first support leg 21, the second support leg 22, and the main body 23 can all conduct electricity. The first support leg 21 is electrically connected to the ground pin 11 corresponding to the first support leg 21, and the second support leg 22 is also electrically connected to the same ground pin 11. Therefore, two parallel current paths are formed between the first current-carrying point 111 and the second current-carrying point 112. The first current path L1 is a path formed in the extension direction of the ground pin 11. The second current path L2 starts from the first current-carrying point 111, passes through the first support leg 21, the main body 23, and the second support leg 22 in succession, reaches the second current-carrying point 112, and then returns to the ground pin 11.

[0071] The shielding sheet 20 is configured to insulate crosstalk that may be caused by the external environment from signals transmitted in the transmission line 10. It can be understood that when two or more ground pins 11 are present, two or more first support legs 21 and two or more second support legs 22 are also present, and each ground pin 11 is electrically connected to one first support leg 21 and one second support leg 22. Because the main body 23 is also conductive and each first support leg 21 and each second support leg 22 are further connected to the main body 23, the main body 23 that extends throughout the entire transmission line 10 electrically connects each ground pin 11, so that the base potential of each ground pin 11 also remains at the same level, effectively insulating crosstalk that may be caused by the external environment from signals transmitted in the transmission line 10.

[0072] FIG. 8 shows an example of a shielding structure in a conventional connector. In the conventional connector, multiple existing transmission lines 10a extending in parallel and an existing shielding sheet 20a configured to implement a shielding function are also arranged. In FIG. 8, there are two existing shielding sheets 20a. For the existing transmission lines 10a, multiple existing ground pins 11a also exist. The existing shielding sheets 20a extend multiple existing support legs 21a from only one side of an existing main body 23a, and each existing support leg 21a is electrically connected to one existing ground pin 11a. The conventional shielding sheets 20a form an open-circuit structure. When an electrical signal in the existing ground pin 11a is conducted to the existing support leg 21a, because there is no structure of the existing support leg 21a on the other side of the existing shielding sheet 20a, the current is conducted to the existing body portion 23a via the existing support leg 21a, and to continue transmitting along the extension path of the existing ground pin 11a, the current must return to the existing ground pin 11a via the same existing support leg 21a. Therefore, while implementing potential balance among the multiple existing ground pins 11a, the existing shielding sheet 20a does not prevent electrical signal current reference feedback, resulting in low-frequency signals in the prior art connector forming crosstalk resonance.

[0073] FIG. 9 shows an example of a crosstalk resonance simulation diagram for a conventional connector. In FIG. 9, the vertical coordinate represents the amplitude of the crosstalk resonance, and the horizontal coordinate represents the frequency of the electrical signal. From the simulation results in FIG. 9, it can be seen that in the conventional connector, the frequency band where the amplitude of the crosstalk resonance is relatively large is a frequency band of approximately 8.5 Hz. This frequency band is within the range of current high-speed signal transmission (28 Gb / s). When the conventional connector transmits a signal, a relatively large crosstalk resonance may be formed because the signal transmission speed of the connector is close to the frequency band. As a result, the integrity of the signal transmitted in the conventional connector is impaired, resulting in poor high-speed signal transmission quality.

[0074] In contrast, the connector 100 of the present application has a first support leg 21 and a second support leg 22 positioned on both sides of the main body 23. Therefore, the shielding sheet 20 can form an electrical path through the main body 23 for the ground pin 11. The current transmitted to the main body 23 via the first support leg 21 returns to the ground pin 11 via the second support leg 22 and continues to travel along the extension direction of the ground pin 11. See FIG. 10 for an example showing a crosstalk resonance simulation diagram of the connector 100 of the present application. After the connector 100 of the present application is constructed based on the above-mentioned solution, the frequency band (solid-line square area) in which the amplitude of the crosstalk resonance of the connector 100 is relatively large is a frequency band of approximately 16 Hz. This frequency band is outside the range of current high-speed signal transmission (28 Gb / s). Therefore, during the operation process of the connector 100 of the present application, the connector 100 is not affected by excessively large crosstalk resonance. That is, the connector 100 of the present application can effectively prevent the signal current reference feedback phenomenon, thereby improving the integrity of the signal transmission of the connector 100.

[0075] It can be understood that since the electronic device 200 of the present application is provided with the connector 100 of the present application, the influence of a relatively large low-frequency crosstalk resonance is not formed in the process of high-speed signal transmission between the first functional component 201 and the second functional component 202 in the electronic device 200 of the present application. In addition to ensuring a higher signal transmission speed of the electronic device 200 of the present application, the integrity and reliability of signal transmission in the electronic device 200 of the present application are also ensured.

[0076] In one embodiment, the first support leg 21 and the second support leg 22 are arranged parallel to the extension direction of the transmission line 10. Specifically, the first support leg 21 is arranged parallel to the extension direction of the transmission line 10, and the first support leg 21 is also parallel to the ground pin 11 electrically connected to the first support leg 21. In this manner, the extension distance from the first conductive end 211 of the first support leg 21 to the main body portion 23 is shortened, that is, the length of the first support leg 21 is reduced. If the first support leg 21 is excessively long, the shielding sheet 20 will form a relatively large inductance effect with the ground pin 11. Therefore, by reducing the length of the first support leg 21, the inductance effect between the shielding sheet 20 and the transmission line 10 can be correspondingly reduced.

[0077] Accordingly, the second support leg 22 is also disposed parallel to the extension direction of the transmission line 10, and therefore the extension distance from the second conductive end 221 of the second support leg 22 to the main body 23 is correspondingly shortened, and the length of the second support leg 22 is also reduced. This also makes it possible to reduce the inductance effect formed by the shielding sheet 20 on the transmission line 10.

[0078] In one embodiment, the length direction of the body portion 23 is set perpendicular to the extension direction of the transmission lines 10. When the body portion 23 spans multiple transmission lines, such as when the transmission lines are parallel to each other and spaced apart, the length of the body portion 23 can be minimized by having the length direction of the body portion 23 perpendicular to the extension direction of the transmission lines 10. In this way, the overall volume and resistance of the body portion 23 are reduced, which also contributes to the inductance effect formed by the shielding sheet 20 on the multiple transmission lines 10 of the present application.

[0079] See FIG. 11 for an example showing the arrangement of multiple transmission lines 10. As described above, the transmission line 10 further includes a ground pin 11 and a signal pin 12. The ground pin 11 cooperates with the signal pin 12 in transmission and is configured to provide a ground potential to ensure the quality of the electrical signal transmitted through the signal pin 12. The ground pin 11 shown in FIG. 11 further includes two side ground pins 113. All of the signal pins 12 in the transmission line 10 are arranged between the two side ground pins 113. One side ground pin 113 is located at an edge on one side of the parallel arrangement direction of the multiple signal pins 12, and the other side ground pin 113 is located at an edge on the other side of the parallel arrangement direction of the multiple signal pins 12. The two side ground pins 113 positioned at the outermost edges on both sides of the multiple signal pins 12 can effectively shield signal crosstalk on each side, thereby ensuring electrical signal transmission of the signal pins 12 positioned between the two side ground pins 113.

[0080] In one embodiment, the ground pins 11 further include a plurality of intermediate ground pins 114. The intermediate ground pins 114 are spaced apart among the plurality of signal pins 12, with at least one signal pin 12 being disposed between any two adjacent ground pins 11. The intermediate ground pins 114 can provide a more reliable shielding effect for the signal pins 12 and prevent signal crosstalk between adjacent signal pins 12.

[0081] In addition, the ground pins 11 include side ground pins 113 and intermediate ground pins 114, and therefore, arranging at least one signal pin 12 between any two adjacent ground pins 11 means that at least one signal pin 12 is arranged between any two adjacent intermediate ground pins 114, and between a side ground pin 113 and an intermediate ground pin 114 adjacent to the side ground pin 113. Any two adjacent ground pins 11 can form a shielding effect for at least one signal pin 12 from opposite sides, thereby ensuring the signal transmission quality of each signal pin 12 in the transmission line 10.

[0082] In one embodiment, the number of signal pins 12 between any two adjacent ground pins 11 is the same. In other words, the ground pins 11 are evenly spaced apart in the multiple transmission lines 10. In this way, the number of signal pins 12 that each ground pin 11 corresponds to and shields from signal crosstalk is also the same, thereby ensuring that the quality of the signals transmitted through each signal pin 12 is the same.

[0083] In the arrangement of the transmission line 10 shown in FIG. 11 , one signal pin 12 is located between two adjacent ground pins 11. In this case, a pair of ground pins 11 is disposed on both sides of each signal pin 12 to provide shielding protection for the signal pins 12, thereby ensuring the signal transmission quality of each signal pin 12. In the arrangement of the transmission line 10 shown in FIG. 12 , two signal pins 12 are located between two adjacent ground pins 11. The two signal pins 12 can cooperate to implement a differential signal transmission scheme. Because the distance between the two signal pins 12 is relatively short, the signal offsets of the two signal pins 12 are often the same under the influence of signal crosstalk. Therefore, using a differential signal transmission scheme can further improve the anti-interference capability of the connector 100 of the present application.

[0084] As described above, the transmission line 10 may alternatively be placed on a flat surface, such as the insulating substrate 33 of a printed circuit board, to transmit signals. FIG. 13 is an example of a cross-sectional view of the transmission line 10 placed on the insulating substrate 33 in the connector 100 of the present application. In this case, the transmission line 10 is the ground pin 11, and the body portion 23 is spaced apart from the ground pin 11 and fixed to the side of the ground pin 11 facing away from the insulating substrate 33. A plurality of first coupling portions 212 are disposed on the first conductive end 211 of the first support leg 21. The plurality of first coupling portions 212 are spaced apart along the extension direction of the ground pin 11 and are connected in parallel to each other. The first coupling portions 212 bend from one side of the body portion 23 toward the ground pin 11 and contact and connect with the ground pin 11. In other words, one first current-carrying point 111 is formed between each first coupling portion 212 and the ground pin 11. Multiple first current-carrying points 111 are arranged at intervals along the extension direction of the ground pin 11. The first coupling portions 212 and the ground pin 11 may be connected to each other by welding or elastic pressing. The provision of multiple first current-carrying points 111 improves the reliability of electrical conduction between the first support leg 21 and the ground pin 11 and forms a shunt function for the electrical signal in the ground pin 11. If one or more first coupling portions 212 have poor contact with the ground pin 11, the electrical signal in the ground pin 11 can still be electrically conducted to the first support leg 21 via the remaining first coupling portions 212.

[0085] Accordingly, a plurality of second coupling portions 222 are also disposed on the second conductive end 221 of the second support leg 22, and the plurality of second coupling portions 222 are also spaced apart along the extension direction of the ground pin 11, and the plurality of second coupling portions 222 are also connected in parallel to one another. The second coupling portions 222 are also bent from one side of the main body 23 toward the ground pin 11, and are in contact with and connected to the ground pin 11. In other words, one second current-carrying point 112 is formed between each second coupling portion 222 and the ground pin 11. The plurality of second current-carrying points 112 are spaced apart along the extension direction of the ground pin 11. The second coupling portions 222 and the ground pin 11 may also be connected to one another by welding or elastic pressing. By providing a plurality of second current-carrying points 112, the reliability of electrical conduction between the second support leg 22 and the ground pin 11 is also improved, and a shunt function for the electrical signal at the ground pin 11 is formed.

[0086] It should be noted that the implementation of multiple first current-carrying points 111 and multiple second current-carrying points 112 may also be applied to various embodiments of the connector 100 shown in FIGS. 2 to 12 to improve the reliability of conduction between the shielding sheet 20 and the ground pin 11 in the aforementioned embodiments. FIG. 13 is used only as an example of the implementation of multiple first current-carrying points 111 and multiple second current-carrying points 112. In addition, the number of first current-carrying points 111 and second current-carrying points 112 may be the same or different. This is not particularly limited in the connector 100 of the present application.

[0087] 14, the shielding sheet 20 is further embedded in the insulating substrate 33, i.e., the shielding sheet 20 and the insulating substrate 33 are positioned on the same side of the ground pin 11. A plurality of first current-carrying points 111 and a plurality of second current-carrying points 112 are also formed between the shielding sheet 20 and the ground pin 11. In the structure shown in FIG. 14, since the shielding sheet 20 and the ground pin 11 are fixed to the insulating substrate 33, the relative positions of the shielding sheet 20 and the ground pin 11 can be further ensured.

[0088] 14 , the connector 100 further includes a shielding cover 40. The shielding cover 40 is positioned on the side of the transmission lines 10 facing away from the insulating substrate 33 and is also configured to provide shielding protection for the transmission lines 10. The shielding cover 40 is a metallic shielding cover that is fixedly disposed within the connector 100 and cooperates with the shielding sheet 20 of the present application to provide shielding protection for the transmission lines 10, and is spaced apart from each transmission line 10 to prevent signal crosstalk. That is, the shielding means of the connector 100 of the present application for the transmission lines 10 is not limited to the shielding sheet 20, and other shielding means capable of achieving a shielding effect may also be applied to the connector 100 of the present application to improve the shielding protection of the transmission lines 10.

[0089] 15 for one embodiment. The shielding sheet 20 further includes a third support leg 24. The third support leg 24 is positioned between the first support leg 21 and the second support leg 22 and is also connected to the main body portion 23. The third support leg 24 also extends from the main body portion 23 toward the ground pin 11 and is electrically connected to the ground pin 11. The third support leg 24 adds an additional current path between the main body portion 23 and the ground pin 11. The current flowing from the first support leg 21 to the main body portion 23 may further flow back to the ground pin 11 via the third support leg 24. Alternatively, the current may flow from the third support leg 24 to the main body portion 23 and then return to the ground pin 11 through the second support leg 22. In the two cases mentioned above, the electrical signal current reference return distance between the ground pin 11 and the shielding sheet 20 is further shortened, i.e., the length of the electrical path between the first current-carrying point 111 and the second current-carrying point 112 is reduced, thereby further reducing the inductance effect that may be caused by the shielding sheet 20 on the transmission line 10.

[0090] 16 for one embodiment. Alternatively, the connector 100 of the present application may be provided with multiple shielding sheets 20. The multiple shielding sheets 20 are arranged at intervals along the extension direction of the ground pin 11 (i.e., the transmission line 10). Each shielding sheet 20 is provided with multiple first support legs 21 and second support legs 22, which are also electrically connected to the ground pin 11. In this embodiment, multiple shielding sheets 20 are provided to provide a shielding protection effect over a larger area in the extension direction of the ground pin 11. In addition, the length of a single shielding sheet 20 may be set to be shorter, which helps to reduce the inductance effect that may be caused by the single shielding sheet 20 on the transmission line 10.

[0091] Furthermore, the main bodies 23 of the multiple shielding sheets 20 may be electrically connected to each other. In the example of FIG. 16 , the main bodies 23 of two shielding sheets 20 are connected to each other using conductive wires 25. Therefore, more electrical paths are formed between the first support leg 21 and the second support leg 22 of each of the two shielding sheets 20, which can further prevent the occurrence of the signal current reference feedback phenomenon and thereby avoid crosstalk resonance of low-frequency signals. It can be understood that in this embodiment, the number of conductive wires 25 is the same as the number of ground pins 11, each conductive wire 25 is also arranged parallel to the extension direction of the ground pin 11, and the position of each conductive wire 25 is aligned with the corresponding ground pin 11 in the direction in which the multiple transmission lines 10 are arranged side by side.
