[0002] This application claims priority to Chinese Patent Application No. 202411874922.5, filed on December 18, 2024, entitled "Connector, Electronic Component, Electronic Device and Signal Transmission Method", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of electronic equipment technology, and in particular to connectors, electronic components, electronic devices, and signal transmission methods. Background Technology

[0004] Electronic devices typically consist of multiple electronic components, which need to transmit signals between each other. With the continuous evolution of electronic devices, the number of transmitted signals is increasing, and the speed is also accelerating. High-speed connectors, as a crucial link in signal transmission, have a significant impact on the operating speed of electronic devices; therefore, higher requirements are placed on the signal transmission rate of high-speed connectors. Furthermore, in addition to the signal transmission rate, increasingly stringent requirements are being placed on the crosstalk immunity, signal integrity, and stability of high-speed connectors. Summary of the Invention

[0005] This application provides connectors, electronic components, electronic devices, and signal transmission methods that improve the shielding effect of connectors against crosstalk signals and increase the signal transmission rate and bandwidth of connectors.

[0006] Firstly, this application provides a connector. The connector includes a fixed structure, a shielding structure, a shielding plate, a cable, and multiple first terminals. Each first terminal includes a signal terminal and a ground terminal. The signal terminal is used to transmit signals, for example, differential signals, and the ground terminal is used for grounding. The first terminal is fixed to the fixed structure, the cable is soldered to the first terminal, and the shielding structure is mounted on the fixed structure and located on the side of the first terminal away from the cable. The shielding plate is located on the side of the first terminal away from the cable, with one end electrically connected to the shielding structure and the other end electrically connected to the ground terminal. This creates a common ground structure for the shielding structure, shielding plate, and ground terminal, forming a complete return current. The orthographic projection of the shielding plate onto a first plane completely covers the soldering area of ​​the first terminal and the cable. The first plane is parallel to the insertion direction of the connector and also parallel to the arrangement direction of the multiple first terminals. The shielding plate reliably shields the soldering area, effectively reducing signal crosstalk in the soldering area, thereby improving the signal transmission rate and bandwidth of the connector.

[0007] The shielding arrangement allows one shield to be electrically connected to all ground terminals on the same layer among multiple first terminals. This design enables the shielding structure, the shield, and all ground terminals to form a common ground structure, creating a complete return current and further reducing signal crosstalk.

[0008] In one specific technical solution, the ground terminals located on the same layer among multiple first terminals are integrated into a single structure. The integrated structure includes a sheet-like region, which is electrically connected to the shielding sheet.

[0009] The connector in this application includes a mating interface through which the opposite connector is inserted. One end of the aforementioned shielding sheet is electrically connected to the end of the shielding structure facing the mating interface, and the other end of the shielding sheet is electrically connected to the end of the ground terminal away from the mating interface. Thus, the shielding sheet can extend from the end of the shielding structure facing the mating interface to the end of the ground terminal away from the mating interface, shielding interference signals over a larger area and reliably improving the signal transmission rate of the connector.

[0010] In one technical solution, the connector's multiple first terminals are arranged in a multi-layer terminal structure, meaning the connector comprises multiple terminal layers, each with a shielding sheet. This solution provides crosstalk shielding for each terminal layer, which helps to further improve the connector's signal transmission rate.

[0011] Specifically, the orthographic projection of the aforementioned shielding sheet on the first plane completely covers the orthographic projection of the soldering areas of all first terminals and cables located on the same layer on the first plane. This solution can improve the reliability of the shielding sheet in shielding crosstalk, and setting one shielding sheet can effectively shield the first terminals in an entire terminal layer from crosstalk.

[0012] The connector described above may also include multiple shielding covers. The first terminal on the same layer includes multiple signal terminal groups, and a ground terminal is provided between any two adjacent signal terminal groups. A shielding cover is attached to the soldering area between a signal terminal group and the cable, and the shielding cover is electrically connected to the ground terminals on both sides of the signal terminal group. Each shielding cover shields one signal terminal group, so crosstalk is less likely to occur between adjacent signal terminal groups, which is beneficial to further improve the signal transmission rate of the connector.

[0013] Specifically, the shielding cover is configured to include a first shielding cover, a second shielding cover, and an additional shielding cover. The first terminal on the same layer includes a first signal terminal group, a second signal terminal group, and a third signal terminal group arranged sequentially adjacent to each other, with a ground terminal between any two adjacent signal terminal groups. The first shielding cover is attached to the welding area between the first signal terminal group and the cable, and is electrically connected to the ground terminals on both sides of the first signal terminal group. The second shielding cover is attached to the welding area between the third signal terminal group and the cable, and is electrically connected to the ground terminals on both sides of the third signal terminal group. The additional shielding cover is attached to the welding area between the second signal terminal group and the cable, and is electrically connected to both the first and second shielding covers. In this design, a shielding cover is directly attached every other signal terminal group, and an additional shielding cover is placed between two adjacent shielding covers, ensuring that each signal terminal has a shielding cover. Each ground terminal only needs to be connected to one shielding cover, which facilitates product engineering implementation.

[0014] Specifically, the shielding covers are configured such that their orthographic projection on the first plane completely covers the soldering areas of the corresponding signal terminal groups and cables. Specifically, the first shielding cover's orthographic projection on the first plane completely covers the soldering areas of the first signal terminal group and cables; the second shielding cover's orthographic projection on the first plane completely covers the soldering areas of the third signal terminal group and cables; and the additional shielding cover's orthographic projection on the first plane completely covers the soldering areas of the second signal terminal group and cables. This design provides reliable protection for the soldering areas and effectively shields against crosstalk.

[0015] Secondly, this application also provides an electronic component. This electronic component includes a first electronic device and any of the connectors provided in the first aspect, wherein the first electronic device is electrically connected to a first terminal of the connector. This electronic component transmits signals at a high rate and with a high bandwidth.

[0016] Thirdly, this application also provides an electronic device. This electronic device includes a housing, a circuit board, and any of the connectors provided in the first aspect. The connector or circuit board is fixed to the housing, and the connector and circuit board are plugged into each other to realize signal transmission between the circuit board and the connector. This electronic device has a high signal transmission rate and bandwidth, which is beneficial for improving the user's communication efficiency.

[0017] Fourthly, this application also provides a signal transmission method. This signal transmission method utilizes any of the connectors provided in the first aspect above to transmit signals. Specifically, the signal transmission method includes: transmitting communication signals through signal terminals; and transmitting ground signals through ground terminals. This scheme provides a higher signal transmission rate and a wider signal bandwidth. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0031] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise.

[0032] References to “an embodiment” or “a specific embodiment” as used in this specification mean that one or more embodiments of this application include a particular feature, structure, or characteristic described in connection with that embodiment. The terms “comprising,” “including,” “having,” and variations thereof mean “including, but not limited to,” unless otherwise specifically emphasized.

[0033] The terms "first" and "second" used in this specification are merely used to distinguish different directions or components, and do not limit the direction or component itself. For example, "first direction" and "second direction" in this application are merely used to express that they are not the same direction, and there are no restrictions on the priority of the direction; "first terminal" and "second terminal" in this application are merely used to express that they are not the same terminal. The first terminal is a terminal of the connector, and there are no restrictions on the position of the first terminal in the connector; the second terminal is a terminal of the opposite connector, and there are no restrictions on the position of the second terminal in the opposite connector.

[0034] To facilitate understanding of the connectors, electronic components, electronic devices, and signal transmission methods provided in the embodiments of this application, their application scenarios will be introduced first below.

[0035] With the development of communication technology, communication bandwidth is increasing. Due to the advantages of optical signals, such as high transmission speed and low loss, applications using optical signals for signal transmission are becoming increasingly widespread. For example, optical module products are used in Passive Optical Networks (PON), wireless networks, and Internet Protocol (IP). Signal transmission requires conversion between optical and electrical signals; therefore, optical modules need to have an electrical signal transmission interface. A commonly used electrical signal transmission interface is the gold finger connector.

[0036] Figure 1 is a schematic diagram of an electronic device according to an embodiment of this application. As shown in Figure 1, the electronic device in this embodiment includes two electronic components 100. For ease of description, one of the two electronic components 100 is considered to be the first electronic component 100a, and the other electronic component 100 is considered to be the second electronic component 100b. The first electronic component 100a includes a connector 1, and the second electronic component 100b includes a peer connector 2, such as a gold finger connector. The first electronic component 100a and the second electronic component 100b are electrically connected through the insertion of the connector 1 and the peer connector 2.

[0037] In this embodiment, connector 1 is a female connector and the other end connector 2 is a male connector. In practical applications, this application does not limit the specific type or shape of connector 1 and the other end connector 2.

[0038] The first electronic component 100a includes a connector 1 and a first electronic device 3. The connector 1 includes a first terminal 11, and the first electronic device 3 is connected to the first terminal 11, thereby enabling the first electronic device 3 to be electrically connected to other electronic components through the connector 1 to transmit signals. In the embodiment shown in FIG1, the first electronic device 3 and the connector 1 are electrically connected via a cable. The first electronic device 3 may specifically be a chip used to perform functions such as storage or computation.

[0039] [Correction based on Rule 91, 02.04.2026] The aforementioned second electronic component 100b can be an electronic module, such as an optical module. The second electronic component 100b includes a housing 4, a second electronic device 5, and a circuit board 6. The circuit board 6 is fixedly mounted on the housing 4, and the second electronic device 5 can be disposed on the circuit board 6. The circuit board 6 includes a gold finger connector, which serves as a peer connector 2. Specifically, the circuit board 6 includes multiple second terminals 61, which are formed as gold finger connectors. The second electronic device 5 is disposed on the circuit board 6 and is electrically connected to the second terminals 61. The gold finger connector of the circuit board 6 serves as a peer connector 2 and is inserted into the connector 1 along the insertion direction, realizing the electrical connection between the second terminals 61 and the first terminal 11, thereby realizing the electrical connection between the first electronic device 3 and the second electronic device 5, and the electrical connection between the first electronic component 100a and the second electronic component 100b. The aforementioned second electronic device 5 can specifically be a chip used to implement functions such as storage or computation.

[0040] In a specific embodiment, the electronic device further includes a housing 200, and either the first electronic component 100a or the second electronic component 100b is fixed to the housing 200. In a specific embodiment, the connector 1 is fixed to the housing 200, or the circuit board 6 is fixed to the housing 200. As shown in the embodiment of FIG1, the connector 1 is fixed to the housing 200, and the circuit board 6 with the opposite connector 2 is connected to the connector 1 via a plug-in connection, thereby fixing it to the housing 200.

[0041] Taking the second electronic component 100b as an optical module as an example, as shown in Figure 1, the first electronic component 100a with connector 1 is fixed to the housing 200. The electronic device may also include a cage 7. When connector 1 and the opposite connector 2 are in a connected state, the second electronic component 100b is fixed inside the cage 7, which helps to improve the fixing strength of the second electronic component 100b, making the second electronic component 100b more reliably fixed to the electronic device, and also helps to improve the connection reliability between connector 1 and the opposite connector 2.

[0042] The electronic devices in this application can be communication devices (such as routers), computing devices (such as servers), network devices (such as switches), or storage devices (such as storage arrays), especially electronic devices with high-speed signal transmission requirements. This application does not limit the specific type of electronic device; any electronic device that requires electrical connection using connectors can adopt the technical solution provided in this application.

[0043] Figure 2 is a schematic diagram of a connector 1 in an embodiment of this application. As shown in Figure 2, in this embodiment, the connector 1 includes a fixing structure 12 and a plurality of first terminals 11, which are fixed to the fixing structure 12. It is understood that the fixing structure 12 is used to fix the first terminals 11. The plurality of first terminals 11 include a signal terminal 111 and a ground terminal 112, wherein the signal terminal 111 is used to transmit signals, and the ground terminal 112 is used for grounding. The signal transmitted by the signal terminal 111 can be a high-speed signal, such as a high-speed differential signal. The ground terminal 112 serves as the return ground, reference ground, and / or shielding structure 13 of the signal terminal 111.

[0044] For ease of connection to the description of the embodiments of this application, as shown in FIG2, the connector 1 includes multiple terminal layers 01, and the multiple terminal layers 01 are arranged along the first direction Z; FIG3 is a top view of the connector 1 in an embodiment of this application. As shown in FIG3, each terminal layer 01 includes multiple first terminals 11, and the multiple first terminals 11 are arranged along the second direction X. The third direction Y refers to the insertion direction of the connector 1. The third direction Y is perpendicular to the first direction Z and perpendicular to the second direction X.

[0045] In one specific embodiment, two signal terminals 111 used to transmit a set of differential signals are grouped together to form a signal terminal group 113, and a ground terminal 112 is provided between any two adjacent signal terminal groups 113.

[0046] Figure 4 is a partial structural schematic diagram of connector 1 in an embodiment of this application. As shown in Figures 2-4, connector 1 further includes a shielding structure 13, a shielding plate 14, and a cable 15. The cable 15 is soldered to the first terminal 11. The cable 15 includes a core 151 for transmitting signals, which is soldered to a signal terminal 111. In one embodiment, cable 15 may further include a shielding portion 152 for shielding signals, which is soldered to a ground terminal 112. Shielding structure 13 is mounted on fixed structure 12 and is located on the side of the first terminal 11 away from cable 15. Specifically, connector 1 includes multiple terminal layers 01, and shielding structure 13 can shield crosstalk between the multiple terminal layers 01. However, the shielding structure 13 has a limited dimension extending in the third direction Y, thus limiting its shielding effect. Therefore, connector 1 in this embodiment of the application also includes a shielding plate 14, which is also located on the side of the first terminal 11 away from cable 15. Furthermore, one end of the shielding plate 14 is electrically connected to the shielding structure 13, and the other end is electrically connected to the ground terminal 112, thereby making the shielding structure 13, the shielding plate 14, and the ground terminal 112 a common ground structure, forming a complete return current. In addition, the orthographic projection of the shielding plate 14 on the first plane M completely covers the orthographic projection of the soldering area 02 of the first terminal 11 and the cable 15 on the first plane M. The first plane M is parallel to the insertion direction of the connector 1 and parallel to the arrangement direction of the multiple first terminals 11. Specifically, the first plane M is parallel to the second direction X and the third direction Y. In the soldering area 02, the wire core 151 and the signal terminal 111 are exposed, which easily leads to signal crosstalk problems, making it difficult to increase the signal transmission rate of the connector 1. The shielding plate 14 can reliably shield the soldering area 02, effectively reducing the signal crosstalk in the soldering area 02, thereby improving the signal transmission rate and bandwidth of the connector 1. This application forms a complete return current, achieving the purpose of reducing module crosstalk by improving the return current path.

[0047] In a specific embodiment, one end of the first terminal 11 is a contact point for connecting to the second terminal 61 of the opposite connector 2. The other end of the first terminal 11 is soldered to the cable. The shielding plate 14 is electrically connected to the ground terminal 112, or the end of the ground terminal 112 away from the contact point can be electrically connected to the shielding plate 14. Specifically, the connection point between the ground terminal 112 and the shielding plate 14 is located at the connection point between the ground terminal 112 and the cable 15. Taking the example of the shielding plate 14 being soldered to the ground terminal 112 and the shielding portion of the cable 15 also being soldered to the ground terminal 112, the solder joint between the shielding plate 14 and the ground terminal 112 is located on the side of the solder joint between the cable 15 and the ground terminal 112 away from the contact point. This allows for relatively reliable shielding of the soldering area 02 between the first terminal 11 and the cable 15.

[0048] In this embodiment, both the shielding structure 13 and the shielding sheet 14 can be made of metal, thereby facilitating the function of shielding crosstalk. For example, the shielding structure 13 and the shielding sheet 14 are both sheet metal structures. The shielding structure 13 can be a sheet-like structure, or the shielding structure can include multiple strip-like portions formed by a hollow structure, etc. Similarly, the shielding sheet 14 can be a sheet-like structure, or the shielding structure can include multiple strip-like portions formed by a hollow structure, etc. In this embodiment, the shielding structure 13 and the shielding sheet 14 are each considered as an integral structure. This integral structure mainly refers to electrical continuity, and the hollow structure can also be considered as part of the integral structure. In short, the shielding structure 13 is not necessarily a regular sheet-like structure, and may include a hollow structure or a bent portion; similarly, the shielding sheet 14 is not necessarily a regular sheet-like structure, and may include a hollow structure or a bent portion.

[0049] In specific embodiments, one terminal layer 01 of connector 1 may be provided with one or more shielding sheets 14. In some embodiments, shielding may be applied only to the soldering areas 02 of a portion of the signal terminals 111, for example, only the soldering areas 02 of the signal terminals 111 used for transmitting high-speed signals may be shielded. When the area where the shielding sheet 14 needs to be provided is not continuous, or when engineering implementation requires avoiding certain structures, one terminal layer 01 of connector 1 may be provided with multiple shielding sheets 14.

[0050] In one embodiment, a shield 14 of connector 1 is electrically connected to all ground terminals 112 located on the same layer of a plurality of first terminals 11. This arrangement enables the shielding structure 13, the shield 14, and all ground terminals 112 to form a common ground structure, creating a complete return current and further reducing signal crosstalk.

[0051] There are several options for the electrical connection between the shielding plate 14 and the ground terminal 112 in this application. For example, the shielding plate 14 can be abutted against the ground terminal 112, or the shielding plate 14 can be soldered to the ground terminal 112. In one specific embodiment, different ground terminals 112 of the connector can be electrically connected to the shielding plate 14 respectively.

[0052] Figure 5 is a schematic diagram of a connector 1 in an embodiment of this application, and Figure 6 is a schematic diagram of a ground terminal 112 in an embodiment of this application. The ground terminals 112 located on the same layer among the multiple first terminals 11 are an integral structure, including a sheet-like region 16, which is electrically connected to a shielding sheet 14. In this embodiment, all ground terminals 112 located on the same layer are connected to the sheet-like structure, and the shielding sheet 14 is electrically connected to the sheet-like structure, thus facilitating the electrical connection between the shielding sheet 14 and all ground terminals 112 on the same layer. Furthermore, the electrical connection between the shielding sheet 14 and the sheet-like structure is a face-to-face electrical connection, which facilitates the electrical connection between the two and ensures high reliability of the electrical connection.

[0053] In a specific embodiment, the shielding sheet 14 can be welded to the sheet-like region 16, which helps to reduce the difficulty of the welding process and improve the connection reliability between the shielding sheet 14 and the ground terminal 112.

[0054] Referring to Figure 5, in a specific embodiment, connector 1 includes a mating interface 17. The opposite connector 2 is inserted into connector 1 through the mating interface 17, thereby connecting connector 2 to connector 1. In one embodiment, the mating interface 17 can also be understood as the edge of connector 1 away from the soldering area 02 between cable 15 and first terminal 11 along the insertion direction. One end of shielding plate 14 is electrically connected to the end of shielding structure 13 facing the mating interface 17; the other end of shielding plate 14 is electrically connected to the end of ground terminal 112 away from the mating interface 17.

[0055] In one embodiment, one end of the shielding sheet 14 is soldered to the end of the shielding structure 13 facing the connector 17, with the solder joint between the shielding sheet 14 and the shielding structure located at the end of the shielding structure 13 facing the connector 17; the other end of the shielding sheet 14 is soldered to the end of the ground terminal 112 away from the connector 17, with the solder joint between the shielding sheet 14 and the ground terminal 112 located at the end of the ground terminal 112 away from the connector 17. Thus, the shielding sheet 14 can extend from the end of the shielding structure 13 facing the connector 17 to the end of the ground terminal 112 away from the connector 17, shielding interference signals over a larger area, thereby improving the shielding effect of the shielding sheet 14 and reliably increasing the signal transmission rate of the connector 1.

[0056] As shown in Figure 5, the surface of the fixing structure 12 facing the insertion interface 17 is the first end face 121, and the shielding structure 13 and the shielding sheet 14 both extend to the first end face 121.

[0057] Furthermore, in this embodiment, the shielding sheet 14 can be electrically connected to the shielding structure 13 by welding, and the shielding sheet 14 can also be electrically connected to the ground terminal 112 by welding. Welding is a simpler and more reliable electrical connection method.

[0058] Figure 7 is a partial structural schematic diagram of connector 1 in an embodiment of this application. As shown in Figure 7, in one embodiment, multiple first terminals 11 are arranged into multiple terminal layers 01, and each terminal layer 01 is provided with a shielding sheet 14. This solution shields each terminal layer 01 from crosstalk, which is beneficial to further improve the signal transmission rate of connector 1.

[0059] Figure 8 is a top view of a connector 1 in an embodiment of this application. As shown in Figure 8, in one embodiment, the orthographic projection of the shielding sheet 14 on the first plane M completely covers the orthographic projection of the soldering areas 02 of all first terminals 11 and cables 15 located on the same layer on the first plane M. This solution can improve the reliability of the shielding sheet 14 in shielding crosstalk, and setting one shielding sheet 14 can achieve the effect of shielding crosstalk for the first terminals 11 of an entire layer.

[0060] [Corrected according to Rule 91, 02.04.2026] Figure 9 is a partial structural schematic diagram of connector 1 in an embodiment of this application, and Figure 10 is a partial top view schematic diagram of connector 1 in an embodiment of this application. As shown in Figures 9 and 10, in one embodiment, connector 1 includes a shielding cover 18, and the first terminal 11 located on the same layer includes multiple signal terminal groups 113. A ground terminal 112 is provided between any two adjacent signal terminal groups 113. A shielding cover 18 is fastened to the soldering area 02 between a signal terminal group 113 and the cable 15, and the shielding cover 18 is electrically connected to the ground terminals 112 on both sides of the signal terminal group 113. Specifically, the shielding cover 18 is disposed on the side of the first terminal 11 away from the shielding sheet, so that multiple shielding covers 18 are correspondingly disposed with multiple signal terminal groups 113. In this scheme, each shielding cover 18 shields one signal terminal group 113, so crosstalk is less likely to occur between adjacent signal terminal groups 113, which is beneficial to further improve the signal transmission rate of connector 1.

[0061] The connector 1's shielding cover 18 includes a first shielding cover 181, a second shielding cover 182, and an additional shielding cover 183. The first terminal 11, located on the same layer, includes a first signal terminal group 1131, a second signal terminal group 1132, and a third signal terminal group 1133 arranged sequentially adjacent to each other. A ground terminal 112 is provided between any two adjacent signal terminal groups 113. In a specific embodiment, each signal terminal group 113 includes a set of differential signal terminals for transmitting a set of differential signals. The first shielding cover 181 is fastened to the soldering area 02 between the first signal terminal group 1131 and the cable 15, and the first shielding cover 181 is electrically connected to the ground terminals 112 on both sides of the first signal terminal group 1131. The second shielding cover 182 is fastened to the welding area 02 between the third signal terminal group 1133 and the cable 15, and is electrically connected to the ground terminals 112 on both sides of the third signal terminal group 1133. The additional shielding cover 183 is fastened to the welding area 02 between the second signal terminal group 1132 and the cable 15, and is electrically connected to the first shielding cover 181 and the second shielding cover 182. Only one ground terminal 112 can be provided between each two adjacent signal terminal groups 113, while a shielding cover 18 is directly provided every other signal terminal group 113. Here, "directly providing a shielding cover 18" means that the shielding cover 18 is directly welded to the ground terminal. Therefore, one ground terminal 112 only needs to be connected to one shielding cover 18. By providing an additional shielding cover 183 between two adjacent shielding covers 18, one shielding structure 13 can be provided for each signal terminal group 113. This solution reduces the complexity of the manufacturing process and facilitates the engineering implementation of the product.

[0062] Please continue referring to Figure 9. In a specific embodiment, the first shielding cover 181 includes a U-shaped cavity, thereby creating a certain distance between the first shielding cover 181 and the aforementioned welding area 02, making it less prone to short circuits. The U-shaped cavity is fastened to the welding area 02 between the first signal terminal group 1131 and the cable 15, and one end of the first shielding cover 181 is electrically connected to the ground terminal 112 on one side of the first signal terminal group 1131, while the other end is electrically connected to the ground terminal 112 on the other side of the first signal terminal group 1131.

[0063] Please continue referring to Figure 9. Similar to the first shielding cover 181, the second shielding cover 182 includes a U-shaped cavity. The welding area 02 between the third signal terminal group 1133 and the cable 15 is located within the U-shaped cavity, thus creating a certain gap between the second shielding cover 182 and the welding area 02, reducing the likelihood of short circuits. The U-shaped cavity is fastened to the welding area 02 between the third signal terminal group 1133 and the cable 15. One end of the second shielding cover 182 is electrically connected to the ground terminal 112 on one side of the third signal terminal group 1133, and the other end is electrically connected to the ground terminal 112 on the other side of the third signal terminal group 1133.

[0064] Please continue to refer to Figure 9. In a specific embodiment, the additional shielding cover 183 may also include a U-shaped cavity, one end of which is electrically connected to the first shielding cover 181 and the other end is electrically connected to the second shielding cover 182.

[0065] In this embodiment, the shielding cover 18 can be a sheet metal structure, which helps to simplify the manufacturing process of the shielding cover.

[0066] Figure 11 is a partial structural schematic diagram of connector 1 in an embodiment of this application. As shown in Figure 11, in one embodiment, the additional shielding cover 183 can be a plate-like structure. One end of the additional shielding cover 183 is electrically connected to the first shielding cover 181, and the other end is electrically connected to the second shielding cover 182. Therefore, the first shielding cover 181 and the second shielding cover 182 can be used to support the additional shielding cover 183, making it less likely for the additional shielding cover 183 and the corresponding soldering area 02 to have a short circuit. In addition, this solution also results in a smaller height for the additional shielding cover 183, which is beneficial for reducing the size of connector 1 along the thickness direction, thereby improving the miniaturization of connector 1.

[0067] Please continue referring to Figure 10. In this embodiment, the first shielding cover 181, when projected onto the first plane M, completely covers the soldering area 02 of the first signal terminal group 1131 and the cable 15, when projected onto the first plane M. The second shielding cover 182, when projected onto the first plane M, completely covers the soldering area 02 of the third signal terminal group 1133 and the cable 15, when projected onto the first plane M. The additional shielding cover 183, when projected onto the first plane M, completely covers the soldering area 02 of the second signal terminal group 1132 and the cable 15, when projected onto the first plane M. This solution provides relatively reliable protection for the soldering area 02 and achieves good crosstalk shielding.
