A high speed connector

Abstract

This application discloses a high-speed connector, belonging to the field of connector technology. This high-speed connector utilizes multiple sets of first signal differential pairs and multiple sets of second signal differential pairs stacked in a first direction. Each set of first signal differential pairs can be covered by a first shielding element, and each set of second signal differential pairs can be covered by a second shielding element. This improves the shielding effect of the first and second signal differential pairs, enhances the crosstalk suppression performance between the first and second signal differential pairs, and improves the crosstalk suppression performance between the second and third signal differential pairs. Simultaneously, when the plug and socket are mated, the first and second shielding contact areas conduct before the first and second signal contact areas, ensuring priority conduction of the grounding terminals of the socket and plug. This guarantees the shielding effect of the first and second signal differential pairs and effectively suppresses electromagnetic crosstalk between the first and second signal differential pairs.

[0002] With the rapid development of communication technology, the transmission rate of electrical signal connectors is constantly increasing, and the requirements for signal crosstalk performance of electrical signal connectors are also becoming more and more stringent.

Detailed Implementation

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0029] Please refer to Figures 1 to 11 This application provides a high-speed connector, including a socket 100 and a plug 200. The plug 200 is configured to mate with the socket 100. It should be noted that the socket 100 in this embodiment can also be called a board-end connector or a female connector, used for mounting on a printed circuit board. The plug 200 can also be called a wire-end connector or a male connector, used for connecting to a cable 90. The socket 100 and plug 200 cooperate to achieve high-speed signal transmission.

[0030] Specifically, the socket 100 includes first signal differential pair groups 110 stacked along a first direction X. Each first signal differential pair group 110 includes a first signal differential pair 1 and a first shielding member 2. A first shielding cavity 2a is formed between the first shielding members 2 of two adjacent first signal differential pair groups 110 along the first direction X, and the first signal differential pair 1 is housed within the first shielding cavity 2a. The first direction X can be the thickness direction of the socket 100. Multiple first signal differential pair groups 110 can be provided. Multiple first signal differential pair groups 110 can be stacked along the first direction X. Each first signal differential pair group 110 includes multiple first signal differential pairs 1 and a matching first shielding member 2. The first shielding member 2 can be a one-piece stamped metal part. The cross-section of the first shielding member 2 can be U-shaped. Along the first direction X, two adjacent first shielding members 2 cooperate to jointly form the first shielding cavity 2a. Each first shielding cavity 2a can accommodate one first signal differential pair 1. Each first signal differential pair 1 is surrounded by the corresponding first shield 2 and the adjacent first shield 2 in the first direction X, thereby electrically isolating the adjacent differential channels of the socket 100, reducing electromagnetic coupling crosstalk between adjacent differential channels, and achieving electromagnetic shielding.

[0031] The plug 200 includes second signal differential pair groups 220 stacked along a first direction X. Each second signal differential pair group 220 includes a second signal differential pair 3 and a second shielding member 4. A second shielding cavity 4a is formed between the second shielding members 4 of two adjacent second signal differential pair groups 220 along the first direction X, and the second signal differential pair 3 is housed within the second shielding cavity 4a. Specifically, multiple second signal differential pair groups 220 can be provided. These multiple groups of second signal differential pair groups 220 can be stacked along the first direction X, and the number of second signal differential pair groups 220 is equal to the number of first signal differential pair groups 110. Each second signal differential pair group 220 includes multiple second signal differential pairs 3 and a matching second shielding member 4. The second shielding member 4 can be a one-piece stamped metal part. The cross-section of the second shielding member 4 can be U-shaped. Along the first direction X, two adjacent groups of second shielding members 4 cooperate to jointly form the second shielding cavity 4a. Each second shielding cavity 4a can accommodate one second signal differential pair 3. Each second signal differential pair 3 is surrounded by a corresponding second shield 4 and an adjacent second shield 4 in the first direction X, thereby electrically isolating adjacent differential channels of the plug 200, reducing electromagnetic coupling crosstalk between adjacent differential channels, and achieving electromagnetic shielding.

[0032] The first shielding component 2 has a first shielding contact area 20, and the second shielding component 4 has a second shielding contact area 40 for conduction with the first shielding contact area 20. The first signal differential pair 1 has a first signal contact area 10, and the second signal differential pair 3 has a second signal contact area 30 for conduction with the first signal contact area 10. When the plug 200 and the socket 100 are connected, the first shielding contact area 20 and the second shielding contact area 40 are configured to conduct before the first signal contact area 10 and the second signal contact area 30. Specifically, the first shielding contact area 20 can be formed on the front end of the first shielding component 2, and the second shielding contact area 40 can be formed on the front end of the second shielding component 4. The first shielding contact area 20 and the second shielding contact area 40 can contact each other to achieve electrical conduction and equipotential grounding. The first signal contact area 10 is formed on the front end of the first signal differential pair 1, and the second signal contact area 30 can be formed on the front end of the second signal differential pair 3. The first signal contact area 10 and the second signal contact area 30 can contact each other to form a differential signal transmission path.

[0033] When the plug 200 and socket 100 are mated, the first shield 2 and the second shield 4 first establish an electrical connection through the first shield contact area 20 and the second shield contact area 40, forming a complete shielding loop. Subsequently, the first signal differential pair 1 and the second signal differential pair 3 establish an electrical connection through the first signal contact area 10 and the second signal contact area 30, forming a complete signal transmission path. That is, during the mating process of the plug 200 and socket 100, the electrical connection between the first shield 2 and the second shield 4 takes precedence over the electrical connection between the first signal differential pair 1 and the second signal differential pair 3. This allows for the timing control of grounding before signal transmission in the plug 200 and socket 100, ensuring that the first signal contact area 10 and the second signal contact area 30 are located in the first shielding cavity 2a and the second shielding cavity 4a respectively before signal transmission begins, thereby effectively suppressing electromagnetic crosstalk. Simultaneously, it effectively prevents electrostatic discharge from damaging the first signal differential pair 1 and the second signal differential pair 3, improving the hot-plug safety of the high-speed connector.

[0034] Thus, by stacking multiple sets of first signal differential pairs 110 and multiple sets of second signal differential pairs 220 in the first direction X, a first shielding cavity 2a for accommodating the first signal differential pair 1 can be formed between adjacent first shielding members 2 in the first direction X, and a second shielding cavity 4a for accommodating the second signal differential pair 3 can be formed between adjacent second shielding members 4. Each set of first signal differential pairs 1 can be covered by the first shielding member 2, and each set of second signal differential pairs 3 can be covered by the second shielding member 4. This improves the shielding effect of the first signal differential pairs 1 and the second signal differential pairs 3, enhances the crosstalk suppression performance between the first signal differential pairs 1, and enhances the crosstalk suppression performance between the second signal differential pairs 3. Simultaneously, when the plug 200 and socket 100 are connected, the first shielding contact area 20 and the second shielding contact area 40 conduct before the first signal contact area 10 and the second signal contact area 30, achieving priority conduction of the grounding terminals of the socket 100 and plug 200. This ensures the shielding effect of the first signal differential pair 1 and the second signal differential pair 3, effectively suppressing electromagnetic crosstalk between each of the first signal differential pair 1 and the second signal differential pair 3, which is beneficial to ensuring the signal integrity of each transmission path and improving the transmission quality of high-speed signals. Furthermore, as... Figure 12 As shown, under a 35GHz bandwidth, after plug 200 and socket 100 are mated, the near-end crosstalk between the first signal differential pair 1 and the second signal differential pair 3 of this high-speed connector is less than -40dB. Figure 13 As shown, under a 35GHz bandwidth, after the plug 200 and socket 100 are mated, the far-end crosstalk between each of the first signal differential pair 1 and the second signal differential pair 3 of the high-speed connector is less than -35dB, which meets the transmission requirements of high-frequency high-speed differential signals.

[0035] Please refer to Figures 5 to 7 The first shielding member 2 has a first opening 2b, which is formed on the circumferential sidewall of the first shielding member 2, so that the first shielding member 2 covers a portion of the outer periphery of the first signal differential pair 1. Specifically, the first opening 2b can be formed on the circumferential sidewall of the first shielding member 2 along the first direction X. That is to say, the first shielding member 2 is not a completely closed cylindrical structure, but has an opening on the circumferential sidewall of the first shielding member 2, so that the first shielding member 2 can form a U-shaped structure, and thus the first shielding member 2 can cover a portion of the outer periphery of the first signal differential pair 1. In this way, by providing the first opening 2b on the first shielding member 2, not only can adjacent first shielding members 2 cooperate with each other to form a closed first shielding cavity 2a when multiple first shielding members 2 are stacked, thereby providing effective electromagnetic shielding for the first signal differential pair 1, but it also facilitates the assembly of the first shielding member 2 and the first signal differential pair 1, reducing the manufacturing and assembly difficulties.

[0036] Please refer to Figure 5 and Figure 11The second shielding member 4 has a second opening 4b, which is formed on the circumferential sidewall of the second shielding member 4 so that the second shielding member 4 covers a portion of the outer periphery of the second signal differential pair 3. Specifically, the second opening 4b can be formed on the circumferential sidewall of the second shielding member 4 along the first direction X. That is to say, the second shielding member 4 is not a completely closed cylindrical structure, but has an opening on the circumferential sidewall of the second shielding member 4, so that the second shielding member 4 can have a U-shaped structure, so that the second shielding member 4 can cover a portion of the outer periphery of the second signal differential pair 3. In this way, by providing a second opening 4b on the second shielding member 4, not only can adjacent second shielding members 4 cooperate with each other to form a closed second shielding cavity 4a when multiple second shielding members 4 are stacked, thereby enhancing the electromagnetic shielding effect on the second signal differential pair 3 to a certain extent, but it also facilitates the assembly of the second shielding member 4 and the second signal differential pair 3, reducing the manufacturing and assembly difficulties.

[0037] Please refer to Figures 3 to 7 as well as Figure 10 and Figure 11 The first opening 2b of each first shield 2 has the same orientation, and the second opening 4b of each second shield 4 has the same orientation. When the plug 200 is connected to the socket 100, the orientation of the first opening 2b is configured to be opposite to the orientation of the second opening 4b.

[0038] Specifically, the orientation of the first opening 2b of each first shield 2 is the same. In the socket 100, the first opening 2b of all first shields 2 faces the same direction. The orientation of the second opening 4b of each second shield 4 is the same. In the plug 200, the second opening 4b of all second shields 4 faces the same direction. In practical applications, the first opening 2b of each first shield 2 can be formed along the first direction X on its respective first shield 2, and correspondingly, the second opening 4b of each second shield 4 can be formed along the opposite direction of the first direction X on its respective second shield 4. Alternatively, the first opening 2b of each first shield 2 can be formed along the opposite direction of the first direction X on its respective first shield 2, and correspondingly, the second opening 4b of each second shield 4 can be formed along the first direction X on its respective second shield 4. Thus, when the plug 200 is mated with the socket 100, the orientation of the first opening 2b is ensured to be opposite to the orientation of the second opening 4b, so that the first shield 2 and the second shield 4 cooperate with each other, improving the overall shielding effect of the high-speed connector.

[0039] It should be noted that when the plug 200 and the socket 100 are connected, the first shield 2 and the second shield 4, whose openings are arranged in opposite directions, can partially overlap in the first direction X, so that the first shield 2 and the second shield 4 can cooperate with each other to surround the periphery of the first signal contact area 10 and the second signal contact area 30, thereby further improving the shielding effect of the signal contact area.

[0040] Thus, when the plug 200 and the socket 100 are properly mated, the first opening 2b of the first shield 2 of the socket 100 and the second opening 4b of the second shield 4 of the plug 200 can complement each other in space, so that the first shield 2 and the second shield 4 cooperate to improve the magnetic leakage problem of the first signal differential pair 1 and the second signal differential pair 3 in the mated state, ensuring that the high-speed connector can meet the transmission requirements of high-frequency and high-speed differential signals.

[0041] Furthermore, in this embodiment, the front end of the first opening 2b of the first shielding member 2 can be covered by the front end of the second shielding member 4, and the front end of the second opening 4b of the second shielding member 4 can also be covered by the front end of the first shielding member 2. This forms a nearly fully enclosed shielding cavity around the first signal contact area 10 and the second signal contact area 30, which helps to completely surround the insertion area of ​​the signal differential pair in the plug 200 and the socket 100, reduce electromagnetic leakage of the high-speed connector, and ensure the shielding effect of the high-speed connector.

[0042] Please refer to Figures 3 to 7 The first shielding member 2 includes a first main body 21 and a stepped part 22 connected to each other. The stepped part 22 is disposed at the front end of the first main body 21, and the front end of the first signal differential pair 1 is recessed in the direction of the first main body 21 relative to the front end of the stepped part 22.

[0043] Specifically, the stepped portion 22 and the first main body portion 21 can be an integral structure. The first main body portion 21 can be U-shaped or C-shaped. The first main body portion 21 is used to cover the main body of the first signal differential pair 1. The stepped portion 22 can be symmetrically arranged at the front end of the first main body portion 21. The stepped portion 22 protrudes further forward than the front end of the first signal differential pair 1. Specifically, the front end of the first signal differential pair 1 is recessed in the direction of the first main body portion 21 relative to the front end of the stepped portion 22. That is, viewed from the mating direction of the plug 200 and the socket 100, the front end of the stepped portion 22 is located in front of the front end of the first signal differential pair 1, so that the front end of the stepped portion 22 can be located in front of the first signal contact area 10 in the mating direction, ensuring that the first shielding member 2 can completely cover the insertion area of ​​the first signal differential pair 1 and the second signal differential pair 3.

[0044] Thus, by setting the stepped portion 22, it is possible not only to facilitate the priority contact between the stepped portion 22 of the first shield 2 and the second shield 4 during the docking process of the plug 200 and the socket 100, but also to ensure the reliability of the priority grounding of the first shield contact area 20 and the second shield contact area 40 from a mechanical structure perspective. Furthermore, it can reduce the electromagnetic leakage of the first signal differential pair 1 at the front end of the first shield 2 and improve the anti-crosstalk capability of the signal contact area of ​​the plug 200 and the socket 100.

[0045] Please refer to Figures 5 to 7 , Figure 10 , Figure 11 and Figure 21 The first shielding contact area 20 includes a shielding sidewall 201, which is formed on the stepped portion 22. Specifically, the shielding sidewall 201 can be formed on the left and right sidewalls of the stepped portion 22. In practical applications, the shielding sidewall 201 can specifically be the front end portion of the two transverse sidewalls of the stepped portion 22.

[0046] The second shielding contact area 40 includes a shielding spring 401, which is formed on the front end of the side wall of the second shielding member 4. Specifically, the shielding spring 401 is located on the front ends of the left and right side walls of the second shielding member 4, that is, the shielding spring 401 can be a cantilever spring structure extending forward and inward from the front end of the side wall of the second shielding member 4. The shielding spring 401 has a certain elastic deformation capability and can elastically abut against the shielding side wall 201 when the plug 200 and the socket 100 are mated.

[0047] The shielding spring 401 is configured to connect with the shielding sidewall 201. Specifically, when the plug 200 mates with the socket 100, the shielding spring 401 at the front end of the second shield 4 first contacts the shielding sidewall 201 of the stepped portion 22 of the first shield 2. Because the shielding spring 401 is elastic, it can undergo a certain elastic deformation during the contact process, thereby maintaining reliable electrical contact between the shielding spring 401 and the shielding sidewall 201, forming a low-impedance shielded conduction path.

[0048] Thus, through the elastic contact between the shielding sidewall 201 and the shielding spring 401, a reliable conductive path can be formed between the first shielding contact area 20 and the second shielding contact area 40, ensuring the continuity and low impedance of the shield. Simultaneously, the elastic contact between the first shielding contact area 20 and the second shielding contact area 40 allows for certain manufacturing tolerances and mating offsets, improving the fault tolerance and reliability of the connection. Furthermore, the elastic contact between the shielding sidewall 201 and the shielding spring 401 provides a self-cleaning effect during the mating process of the plug 200 and the socket 100, removing oxide layers and contaminants from the surfaces of the first shielding contact area 20 and the second shielding contact area 40, maintaining stable contact resistance.

[0049] In this embodiment, please refer to the following: Figure 19 To ensure the reliability of the electrical connection between the first shielding contact area 20 and the second shielding contact area 40, the length of the shielding spring 401 needs to be sufficiently long to guarantee a sufficiently large contact area between the shielding spring 401 and the shielding sidewall 201. Specifically, the shielding sidewall 201 can extend from the sidewall of the stepped portion 22 to the sidewall of the first main body portion 21; that is, the shielding sidewall 201 can be formed simultaneously on the sidewalls of both the stepped portion 22 and the first main body portion 21. This increases the contact area between the shielding sidewall 201 and the shielding spring 401, ensuring the shielding reliability of the first shielding contact area 20 and the second shielding contact area 40.

[0050] Please refer to Figure 3 as well as Figures 5 to 7 The first signal differential pair 1 includes a first encapsulation 11 and a first signal terminal 12 embedded within the first encapsulation 11. The two ends of the first signal terminal 12 extend from both ends of the first encapsulation 11, and a first signal contact area 10 is formed at the front end of the first signal terminal 12. Specifically, the first encapsulation 11 may be made of insulating plastic. The first encapsulation 11 may be manufactured using processes including, but not limited to, injection molding. The first encapsulation 11 may cover the central region of the first signal terminal 12. Each first signal differential pair 1 includes two first signal terminals 12 arranged side-by-side. The first signal terminal 12 is in the form of a long strip of metal conductive sheet. The two ends of the first signal terminal 12 extend from both ends of the first encapsulation 11, i.e., the portion of the front end of the first signal terminal 12 extending out of the first encapsulation 11 forms the first signal contact area 10, and the portion of the rear end of the first signal terminal 12 extending out of the first encapsulation 11 is used for connection to the signal circuit of the printed circuit board. The first encapsulation 11 provides insulation support for the first signal terminal 12 and keeps the two first signal terminals 12 of the first signal differential pair 1 in a stable relative position, thus ensuring the structural reliability of the first signal differential pair 1.

[0051] In this embodiment, the first signal contact area 10 may be a planar area or an elastic arm structure at the front end of the first signal terminal 12, and no specific limitation is made here.

[0052] Please refer to Figure 8 , Figure 10 and Figure 11 The second signal differential pair 3 includes a second encapsulation 31 and a second signal terminal 32 embedded within the second encapsulation 31. Both ends of the second signal terminal 32 extend from both ends of the second encapsulation 31, and a second signal contact area 30 is formed at the front end of the second signal terminal 32. Specifically, the second encapsulation 31 can be made of insulating plastic. The second encapsulation 31 can be processed by processes including but not limited to injection molding. The second encapsulation 31 can cover the central region of the second signal terminal 32. Each second signal differential pair 3 includes two second signal terminals 32 arranged side-by-side. Both ends of the second signal terminal 32 extend from both ends of the second encapsulation 31, i.e., the portion of the front end of the second signal terminal 32 extending out of the second encapsulation 31 forms the second signal contact area 30, and the portion of the rear end of the second signal terminal 32 extending out of the second encapsulation 31 is used for soldering to the end of the core wire 902 of the cable 90 for conduction. The second encapsulation 31 provides insulation support for the second signal terminal 32 and keeps the two second signal terminals 32 of the second signal differential pair 3 in a stable relative position, thus ensuring the structural reliability of the second signal differential pair 3.

[0053] In this embodiment, the second signal contact area 30 may be a planar area at the front end of the second signal terminal 32 or an elastic arm structure, and no specific limitation is made here.

[0054] It should be noted that, in order to ensure the reliability of the electrical connection between the first signal contact area 10 and the second signal contact area 30, the first signal contact area 10 is either a planar region or an elastic arm structure, and the second signal contact area 30 is either a planar region or an elastic arm structure. This helps to reduce the contact impedance of the first signal contact area 10 and the second signal contact area 30 when they are in elastic contact, thus ensuring the reliability of their electrical connection.

[0055] Thus, by integrating the first molding compound 11, the first signal terminal 12, the second molding compound 31, and the second signal terminal 32, not only can the number of loose parts of the first signal differential pair 1 and the second signal differential pair 3 be reduced, improving the assembly efficiency and positional accuracy of the first signal differential pair 1 and the second signal differential pair 3, but the first molding compound 11 and the second molding compound 31 can also provide additional dielectric isolation and mechanical protection for the signal terminals inside the high-speed connector, ensuring the reliability of the high-speed connector during use.

[0056] Please refer to Figure 3 , Figures 5 to 7 as well as Figure 19 The first shield 2 has a wall surface 214 formed on its circumferential sidewalls, the wall surface 214 facing the first opening 2b, and the first signal terminal 12 is located on the side of the wall surface 214 opposite to the first opening 2b, so that the first signal terminal 12 is accommodated inside the first shield 2.

[0057] Specifically, the first shielding member 2 forms a wall surface 214 on each of its two transverse side walls while forming the first opening 2b. The wall surface 214 faces the first opening 2b, that is, the wall surface 214 is directly opposite the first opening 2b. The wall surface 214 and the first opening 2b are located on the same side of the first shielding member 2 in the first direction X. When the first opening 2b is located on one side of the first shielding member 2 in the first direction X, the first signal terminal 12 and the wall surface 214 are arranged sequentially along the first direction X, and the wall surface 214 is higher than the first signal terminal 12. When the first opening 2b is located on the opposite side of the first shielding member 2 in the first direction X, the first signal terminal 12 and the wall surface 214 are arranged sequentially in the opposite direction of the first direction X, and the wall surface 214 is lower than the first signal terminal 12. That is, in the first direction X, the first signal terminal 12 is located on the side of the wall surface 214 opposite to the first opening 2b, thereby allowing the first signal terminal 12 to be accommodated inside the first shielding member 2.

[0058] It should be noted that, in practical applications, the wall surface 214 can be formed simultaneously on the walls of the first main body 21 and the stepped part 22 facing the first opening 2b.

[0059] Thus, by setting the first signal terminal 12 on the side of the wall 214 opposite to the first opening 2b, the first signal terminal 12 can be accommodated inside the first shield 2. When the plug 200 and the socket 100 are connected, it can not only ensure that the shielding spring 401 overlaps with the shielding sidewall 201 located between the first signal terminal 12 and the wall 214 in the first direction X, but also ensure that the overlapping part of the shielding spring 401 and the shielding sidewall 201 can surround the first signal contact area 10 of the first signal terminal 12 from both sides, which helps to improve the signal shielding effect of the first signal terminal 12.

[0060] Please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7The first molding compound 11 has a first sub-positioning portion 111, and the first shielding member 2 has a first female positioning portion 211. The first sub-positioning portion 111 is configured to insert into the first female positioning portion 211. Specifically, the first sub-positioning portion 111 can be one of a protrusion and a groove, and the first female positioning portion 211 can be the other of a protrusion and a groove. The protrusion and groove are mutually compatible. The first sub-positioning portion 111 can be located at the top or bottom of the first molding compound 11. Correspondingly, the first female positioning portion 211 is located on the first shielding member 2 at a position corresponding to the first sub-positioning portion 111. Thus, when the first molding compound 11 and the first shielding member 2 are assembled, the first sub-positioning portion 111 and the first female positioning portion 211 insert into each other, and the sidewalls of the first shielding member 2 and the first molding compound 11 can fit together, jointly achieving the assembly positioning of the first shielding member 2 and the first molding compound 11, preventing axial movement of the first molding compound 11 and the first shielding member 2.

[0061] The first molding compound 11 has a second sub-positioning portion 112, and the first shielding member 2 has a second female positioning portion 212. The second sub-positioning portion 112 is configured to insert into the second female positioning portion 212. Specifically, the second sub-positioning portion 112 can be one of a protrusion and a groove, and the second female positioning portion 212 can be the other of a protrusion and a groove. The protrusion and groove are mutually adapted. The second sub-positioning portion 112 can be disposed on the side wall of the first molding compound 11. Correspondingly, the second female positioning portion 212 is disposed on the side wall of the first shielding member 2. Thus, when the first molding compound 11 and the first shielding member 2 are assembled, the second sub-positioning portion 112 and the second female positioning portion 212 insert into each other, while the portion between the two side walls of the first shielding member 2 and the top or bottom of the first molding compound 11 are in contact with each other, jointly achieving the assembly positioning of the first shielding member 2 and the first molding compound 11, preventing axial movement of the first molding compound 11 and the first shielding member 2.

[0062] It should be noted that the first molding compound 11 may simultaneously have a first sub-positioning part 111 and a second sub-positioning part 112. Correspondingly, the first shielding member 2 may simultaneously have a first female positioning part 211 and a second female positioning part 212. The first sub-positioning part 111 and the second sub-positioning part 112 are located at different positions on the first molding compound 11, and the first female positioning part 211 and the second female positioning part 212 are located at different positions on the first shielding member 2. The two sets of positioning structures can cooperate with each other, further improving the assembly reliability of the first molding compound 11 and the first shielding member 2.

[0063] Thus, by setting multiple sets of mutually cooperating positioning structures on the first encapsulation body 11 and the first shielding member 2, it can be ensured that the first shielding member 2 is accurately installed in the preset position of the first encapsulation body 11, avoiding the first shielding member 2 from being tilted or displaced, ensuring the coverage accuracy of the first signal differential pair 1 by the first shielding member 2, and improving the consistency of the shielding effect of different first signal differential pair groups 110.

[0064] In other embodiments, since the first shielding member 2 has a first opening 2b and partially covers the first encapsulation body 11, the second sub-positioning part 112 can be provided on the protrusion on the side wall of the first encapsulation body 11 not covered by the first shielding member 2. The second sub-positioning parts 112 of the first encapsulation bodies 11 of adjacent first signal differential pairs 1 in the same row can be connected to each other, so that the first encapsulation bodies 11 of each group of first signal differential pairs 10 form a whole. In this way, the processing difficulty of the first encapsulation body 11 can be reduced and the processing efficiency of the first encapsulation body 11 can be improved. Moreover, the assembly accuracy and assembly efficiency between each first signal differential pair 1 and the first shielding member 2 in each group of first signal differential pairs 10 can be improved. This helps to keep the relative positions of each first signal differential pair 1 and the first shielding member 2 consistent, and reduces the impact of positional errors of adjacent first signal differential pairs 1 and the first shielding member 2 on the anti-crosstalk performance between different first signal differential pairs 1.

[0065] Please refer to Figure 3 , Figure 4 , Figure 6 , Figure 7 as well as Figures 14 to 19 The socket 100 also includes a first base 5, which has an array of first channels 501 arranged in an array, and a first signal differential pair 1 is disposed within the first channel 501. Specifically, the first base 5, as the main support component of the socket 100, can be made of insulating plastic. The first base 5 can generally be in the shape of a rectangular block. The first base 5 has an array of first channels 501 arranged in an array. The first channel 501 can be a groove penetrating the first base 5 in the front-to-back direction, and the multiple first channels 501 can be arranged according to a certain row spacing and column spacing. Each first channel 501 accommodates a first signal differential pair 1. The first signal differential pair 1 can be fixed within the first channel 501 by a first shield 2.

[0066] The first shielding member 2 is provided with an embedding portion 213, which is embedded in the inner wall of the first channel 501. Specifically, the embedding portion 213 may be, but is not limited to, a barbed structure. The embedding portion 213 may be formed on the side wall of the first shielding member 2. The embedding portion 213 may be embedded in the inner wall of the first channel 501. Specifically, when the first shielding member 2 is inserted into the first channel 501, the embedding portion 213 will be inserted into the inner wall of the first channel 501, thereby enabling the first shielding member 2 to form an interference fit with the first channel 501, preventing the first shielding member 2 from being removed from the first channel 501. In this way, by providing the embedding portion 213, a backstop function can be provided for the first shielding member 2 within the first channel 501, preventing the first signal differential pair 1 from shaking within the first channel 501 during repeated plugging and unplugging scenarios.

[0067] A stop protrusion 51 is formed on the inner wall of the first channel 501, which is used to limit the first shielding member 2. Specifically, the stop protrusion 51 can be a block-shaped structure protruding from the inner sidewall of the first channel 501 toward the inner side of the first channel 501. The stop protrusion 51 can limit the stepped portion 22 of the first shielding member 2. Specifically, when the first shielding member 2 is inserted into the first channel 501 from the rear end, the front end face of the stepped portion 22 can move forward along the first channel 501 until it abuts against the rear end face of the stop protrusion 51, thereby preventing the first shielding member 2 from moving too far forward in the first channel 501, realizing the accurate positioning of the first signal differential pair 1 in the first channel 501, and improving the stability of the first signal differential pair 1 in the first channel 501.

[0068] It should be noted that since the first shielding member 2 needs to be inserted into the first channel 501, the insert 213 is usually inclined to allow it to smoothly enter the first channel 501. However, this inclined arrangement reduces the connection strength between the first shielding member 2 and the first channel 501 in the assembly direction. To address this issue, a stop protrusion 51 is provided to prevent the first shielding member 2 from exiting the first channel 501 in the opposite direction of the assembly direction. The stop protrusion 51 also restricts the position of the first shielding member 2 within the first channel 501, preventing excessive forward movement and ensuring precise assembly and stable connection between the first shielding member 2 and the first molding compound 11, thus improving the stability of the first signal differential pair 1 within the first channel 501.

[0069] The rear end of the first shielding member 2 is provided with a first folded portion 23, which is coplanar with the rear end of the first signal terminal 12. The first folded portion 23 is used to connect to the grounding circuit of the printed circuit board, and the rear end of the first signal terminal 12 is used to connect to the signal circuit of the printed circuit board. Specifically, the first folded portion 23 can be a flat sheet-like structure formed by folding outward from the rear edge of the first shielding member 2. The coplanar arrangement of the first folded portion 23 and the rear end of the first signal terminal 12 facilitates synchronous soldering. The first folded portion 23 is used to connect to the grounding circuit of the printed circuit board. The rear end of the first signal terminal 12 is used to connect to the signal circuit of the printed circuit board. In practical applications, both the first folded portion 23 and the rear end of the first signal terminal 12 can be connected to the grounding circuit pad of the printed circuit board by surface mount soldering or other methods. Thus, by setting the rear ends of the first folding portion 23 and the first signal terminal 12 to be coplanar, during the assembly process of the socket 100 and the printed circuit board, the rear ends of the first folding portion 23 and the first signal terminal 12 can simultaneously contact the grounding circuit and the signal circuit of the printed circuit board, which facilitates the soldering and conduction of the grounding circuit and the signal circuit of the socket 100 and the printed circuit board. To a certain extent, this can simplify the assembly process of the socket 100 and the printed circuit board and improve the production efficiency of the socket 100 and the printed circuit board.

[0070] It should be noted that, in order to adapt to the layout of the signal circuits on the printed circuit board, the rear end portion of the first signal terminal 12 of the first signal differential pair group 110 of the socket 100 can be adaptively modified. For example... Figure 6 and Figure 7 The rear end portion of the first signal terminal 12 can be configured as a U-shaped structure, thereby changing the position of the rear end portion of the first signal terminal 12 of the first signal differential pair group 110, so as to match the structure of the signal circuit on the printed circuit board and enhance the structural adaptability of the socket 100.

[0071] Please refer to Figures 1 to 3 , Figure 14 , Figure 15 , Figure 17 and Figure 18 The socket 100 also includes a first housing 6, which is fitted onto the first base 5. The first housing 6 serves as the outer metal shell of the socket 100 and can be made of sheet metal by stamping. The first housing 6, fitted onto the outer periphery of the first base 5, not only provides structural protection and reinforcement for the internal first base 5 and the first signal differential pair group 110, but also provides additional electromagnetic shielding for the inner first signal differential pair 1.

[0072] A second folding portion 61 is provided at the rear end of the first housing 6, and the second folding portion 61 is disposed at the rear end of the first base 5. Specifically, the second folding portion 61 can be a sheet-like structure formed by folding inward from the rear end edge of the first housing 6. The second folding portion 61 is disposed at the rear end of the first base 5, specifically it can be attached to the rear end surface of the first base 5 or embedded in a corresponding groove at the rear end of the first base 5. The provision of the second folding portion 61 can prevent the first base 5 from moving rearward relative to the first housing 6, which helps to improve the connection reliability between the first base 5 and the first housing 6.

[0073] The first base 5 is provided with a first sub-stop portion 52, and the first housing 6 is provided with a first female stop portion 62, with the first sub-stop portion 52 disposed within the first female stop portion 62. Specifically, the first sub-stop portion 52 can be one of a stop block and a groove, and the first female stop portion 62 can be the other of a stop block and a groove. The stop block and the groove are structurally matched. Thus, when the first housing 6 is fitted onto the first base 5, the first sub-stop portion 52, disposed within the first female stop portion 62, forms a limiting fit, preventing the first base 5 from moving forward relative to the first housing 6, thereby improving the connection reliability between the first base 5 and the first housing 6.

[0074] It should be noted that, through the cooperation of the second folding part 61 with the first male stop part 52 and the first female stop part 62, the first base 5 can be locked in the first housing 6 in the front-back direction, preventing the first base 5 from coming out of the first housing 6, and realizing a stable connection between the first housing 6 and the first base 5.

[0075] The first base 5 is provided with a sub-auxiliary connecting part 53, and the first housing 6 is provided with a female auxiliary connecting part 63. The sub-auxiliary connecting part 53 is configured to plug into the female auxiliary connecting part 63. Specifically, the sub-auxiliary connecting part 53 can be one of an L-shaped plate and an L-shaped groove, and the female auxiliary connecting part 63 can be the other of an L-shaped plate and an L-shaped groove. The L-shaped plate and the L-shaped groove are mutually compatible. The sub-auxiliary connecting part 53 can be located on the top of the first base 5. The female auxiliary connecting part 63 can be located on the top of the first base 5. When assembling the first base 5 and the first housing 6, the sub-auxiliary connecting part 53 and the female auxiliary connecting part 63 can plug into each other. Through their cooperation, the assembly process of the first housing 6 and the first base 5 can be guided, so that the first sub-stop part 52 and the first female stop part 62 can be accurately connected. To a certain extent, this can reduce the assembly difficulty of the first housing 6 and the first base 5 and help improve the assembly efficiency of the socket 100.

[0076] The front end of the first housing 6 is provided with a first guide portion 64, which is configured to guide the plug 200 to mate with the socket 100. Specifically, the first guide portion 64 may be a flared edge that folds outward from the front edge of the first housing 6, or it may be a flared guide surface. The first guide portion 64 is configured to guide the plug 200 to mate with the socket 100. That is, when the plug 200 and the socket 100 mate, the plug 200 can contact the first guide portion 64 first. The first guide portion 64 can guide the front end of the plug 200 to a position directly opposite the socket 100, so that the first signal differential pair 1 of each row of the first signal differential pair group 110 of the plug 200 can conduct with the second signal differential pair 3 of each row of the second signal differential pair group 220 of the socket 100. At the same time, it can enable the first shield 2 to conduct with the second shield 4, avoiding damage to the internal structures such as the first signal differential pair 1, the second signal differential pair 3, the first shield 2, and the second shield 4 due to misalignment of the plug 200 and the socket 100.

[0077] Please refer to Figure 8 , Figure 10 and Figure 11 The second shield 4 has an overlap portion 41, which is located at the rear end of the second shield 4 and is configured to be electrically connected to the ground wire 901 of the cable 90. Specifically, the overlap portion 41 can be a soldering tab structure located at the rear end of the second shield 4. The overlap portion 41 and the cable 90 can be connected by means including but not limited to soldering, so that the overlap portion 41 can be electrically connected to the ground wire 901 of the cable 90. Electromagnetic interference from the ground wire 901 of the cable 90 can be conducted to the second shield 4 through the overlap portion 41, thereby introducing the grounding signal of the cable 90 into the second shield 4 and forming an independent grounding return path on the plug 200 side. In addition, the rear end of the second signal terminal 32 is configured to be electrically connected to the core wire 902 of the cable 90. Specifically, the rear end of the second signal terminal 32 extends from the rear end of the second molding compound 31 to the soldering area of ​​the cable 90. The rear end of each second signal terminal 32 can be soldered to one core wire 902 of the cable 90 to realize the transmission of signal from the cable 90 to the second signal terminal 32.

[0078] Thus, by electrically connecting the core wire 902 of the cable 90 to the rear end of the second signal terminal 32 to transmit high-speed signals, and simultaneously electrically connecting the ground wire 901 of the cable 90 to the overlap portion 41 of the second shield 4 to achieve grounding return, it helps to form a complete signal transmission path and shielding grounding path between the high-speed connector and the cable 90, the plug 200 and the socket 100.

[0079] In this embodiment, overlapping portions 41 can be provided on both sides of the rear end of the second shield 4, and each overlapping portion 41 can extend in a direction away from the main body of the second shield 4. The overlapping portions 41 of adjacent second shields 4 in each group of second signal differential pairs 220 can be connected to each other, so that each second shield 4 in the group of second signal differential pairs 220 can form a whole. In this way, the processing difficulty of the second shield 4 can be reduced and the processing efficiency of the second shield 4 can be improved. Moreover, the assembly accuracy and assembly efficiency between each first signal differential pair 1 and the second shield 4 in each group of second signal differential pairs 220 can be improved. This helps to keep the relative positions of each second signal differential pair 3 and the second shield 4 consistent, and reduces the impact of positional errors of adjacent second signal differential pairs 3 and the second shield 4 on the anti-crosstalk performance between different second signal differential pairs 3.

[0080] Please refer to Figure 1 , Figure 2 , Figure 8 as well as Figures 9 to 11 The plug 200 also includes a second base 7, which has an array of multiple second channels 701 arranged in an array, and the second signal differential pairs 3 are disposed within the second channels 701. Specifically, the second base 7, as the main support component of the plug 200, can be made of insulating plastic. The second base 7 has an array of multiple second channels 701 arranged in an array. The second channels 701 can be grooves extending through the second base 7 in a front-to-back direction, and the multiple second channels 701 can be arranged according to row and column spacing corresponding to the first channels 501 on the first base 5. Each second channel 701 accommodates a second signal differential pair 3 and a second shield 4. The second signal differential pairs 3 and the second shield 4 are assembled and installed within the second channel 701. Thus, when the plug 200 and the socket 100 are connected, it is ensured that the multiple second signal differential pairs 3 on the plug 200 can be connected to the multiple first signal differential pairs 1 on the socket 100, and the multiple second shielding components 4 on the plug 200 can be connected to the multiple first shielding components 2 on the socket 100, thereby achieving precise connection between the internal signal path and shielding path of the plug 200 and the socket 100.

[0081] Adjacent second molding compounds 31 are interconnected. Specifically, the multiple second molding compounds 31 of each group of second signal differential pairs 220 can be manufactured by integral molding. In this way, the multiple second molding compounds 31 of each group of second signal differential pairs 220 can be formed into an integral structure, and correspondingly, the multiple second shielding members 4 can also be formed into an integral structure, thereby improving assembly efficiency, increasing the assembly accuracy between the second signal differential pairs 3 and the second shielding members 4, and improving the assembly efficiency between each group of second signal differential pairs 3 and the second base 7, which helps to improve the production efficiency of the socket 100.

[0082] Furthermore, an assembly groove 311 is formed between adjacent second molding bodies 31. A separator 71 is formed between adjacent second channels 701. The assembly groove 311 is configured to move along the separator 71. Specifically, the front ends of adjacent second molding bodies 31 are integrally formed with spaced-apart assembly grooves 311. The second base 7 forms a plurality of spaced-apart second channels 701 while forming a separator 71 between adjacent second channels 701. The separator 71 can be a plate-like structure. When each group of second signal differential pairs 220 is assembled with the second base 7, the plurality of connected second molding bodies 31 can move along the separator 71 through the assembly groove 311, so that each second signal differential pair 3 and the second shield 4 of the second signal differential pair group 220 slides into the corresponding second channel 701 of the second base 7. In this way, multiple second signal differential pairs 3 and second shielding components 4 of each group of second signal differential pairs 220 can be assembled into the second channel 701 of the second base 7 at one time, without having to install the second signal differential pairs 3 and second shielding components 4 one by one into the second channel 701, thus improving the overall assembly efficiency of the plug 200. In addition, the separator 71 between adjacent second channels 701 can guide and limit the assembly slot 311, ensuring that each second plastic encapsulation body 31 can be accurately installed into the second channel 701.

[0083] It should be noted that the rear end of the separator 71 is formed with a stop surface 711. During the assembly process of the second signal differential pair 220 and the second base 7, the assembly groove 311 moves along the separator 71 until the bottom surface of the assembly groove 311 moves to the stop surface 711, which indicates that the second signal differential pair 220 and the second base 7 are assembled in place.

[0084] The plug 200 also includes a second housing 8, which is disposed at the rear end of the second base 7. The second housing 8 is configured to fix the second molding compound 31 within the second channel 701. Specifically, the second housing 8 serves as the outer metal shell of the plug 200 and can be made of sheet metal by stamping. After the second signal differential pair 3 is inserted into the second channel 701 from the rear end of the second base 7, the second housing 8 can be installed at the rear end of the second base 7. The second housing 8 can fix the second signal differential pair 3 and the second shield 4 within the second channel 701 of the second base 7, preventing the second signal differential pair 3 and the second shield 4 from dislodging from the second channel 701.

[0085] Please refer to Figure 1 , Figure 2 , Figure 15 and Figure 20 The second housing 8 has a first sub-snap connector 81, and the second base 7 has a first female snap connector 72. The first sub-snap connector 81 is configured to snap into the first female snap connector 72.

[0086] Specifically, the first sub-attachment 81 can be either a snap-fit ​​or a slot, and the first female attachment 72 can be either a snap-fit ​​or a slot. The first sub-attachment 81 is disposed on the periphery of the second housing 8. The first female attachment 72 is disposed on the periphery of the second base 7. The first female attachment 72 and the first sub-attachment 81 are mutually compatible. During the assembly of the second housing 8 and the second base 7, the second housing 8 can be installed at the rear end of the second base 7, and the first sub-attachment 81 and the first female attachment 72 snap together, thus connecting and fixing the second housing 8 to the second base 7. Furthermore, through the assembly of the second housing 8 and the second base 7, the second signal differential pair 220 can be fixed within the second channel 701 of the second base 7, thus assembling the second signal differential pair 220.

[0087] Thus, through the snap-fit ​​engagement of the first female snap-fit ​​part 81 and the first female snap-fit ​​part 72, the assembly structure of the second housing 8 and the second base 7 can be simplified without the need for additional fasteners such as screws, thereby reducing assembly costs, facilitating the subsequent disassembly of the plug 200, and benefiting the maintenance and replacement of the plug 200.

[0088] Please refer to Figure 8 , Figure 10 and Figure 15 The plug 200 also includes an isolator 91 disposed between adjacent cables 90, configured to isolate adjacent cables 90. Specifically, the isolator 91 can be a thin sheet structure made of insulating material. Multiple spaced grooves can be formed on both sides of the isolator 91, and each groove can accommodate one cable 90, thereby separating multiple cables 90 and preventing displacement of the cables 90 during subsequent processing.

[0089] In addition, the plug 200 also includes a filler 92, which is disposed on both sides of the isolator 91. The filler 92 is configured to encapsulate the isolated cable 90. Specifically, the filler 92 can be made of insulating encapsulating material. After the cable 90 is positioned by the isolator 91, liquid insulating plastic is subsequently molded in a mold through low-pressure injection molding or potting process. The molded filler 92 can cover the core wires 902 of the multiple cables 90 positioned by the isolator 91, the rear end of the second signal terminal 32, and the welding points of the overlap 41 and the ground wire 901, preventing external moisture, dust, etc. from corroding the welding points of the cable 90 and the second signal differential pair 220, reducing the risk of failure at the connection between the cable 90 and the second signal differential pair 220, and ensuring the electrical performance of the plug 200. Meanwhile, the isolator 91 and the fillers 92 on both sides can be connected to form an integral whole. The integral structure formed by the isolator 91 and the fillers 92 can be adapted to the rear end of the second base 7 and the front end of the second housing 8. When the integral structure formed by the isolator 91 and the fillers 92 is installed into the second base 7 along with the second signal differential pair 220, the second housing 8 can be assembled to the rear end of the second base 7, thereby fixing the isolator 91, the fillers 92 and the second signal differential pair 220 together, improving the assembly efficiency of the plug 200.

[0090] Please refer to Figures 1 to 3 , Figure 8 , Figure 17 , Figure 18 and Figure 20 The plug 200 also includes a locking member 93, which is disposed on the second base 7. The first housing 6 has a locking part 65, and the locking member 93 is inserted into the locking part 65. The locking member 93 has a second female engagement part 931, and the locking part 65 has a second female engagement part 651. The second female engagement part 931 is configured to engage with the second female engagement part 651.

[0091] Specifically, the locking member 93 is fixedly mounted on the second base 7. The front end of the locking member 93 has a certain elastic deformation capability, meaning that the front end of the locking member 93 can rotate within a certain range under tensile force. Correspondingly, the first housing 6 has a locking part 65. The locking part 65 can be a lock hole structure protruding outward from the side wall of the first housing 6. The locking part 65 is adapted to the locking member 93. When the plug 200 and the socket 100 are mated, the locking member 93 can be inserted into the locking part 65.

[0092] The locking member 93 has a second sub-engagement 931 at its front end, and the locking member 65 has a second female engagement 651. The second sub-engagement 931 is one of a locking block and a locking groove, and the second female engagement 651 is the other of a locking block and a locking groove. When the plug 200 is fully engaged with the socket 100, operating the locking member 93 can engage the second sub-engagement 931 with the second female engagement 651, thereby locking the plug 200 onto the socket 100 and preventing the plug 200 from accidentally separating from the socket 100.

[0093] Furthermore, the locking member 93 may also include a pulling member 932. The pulling member 932 may be in the form of, but is not limited to, a pull strap. The pulling member 932 is disposed at the front end of the locking member 93 and is used to assist in unlocking the locking member 93 from the locking part 65. Thus, when the plug 200 and the socket 100 are fully engaged, pulling the pulling member 932 can move the front end of the locking member 93, thereby causing the second female locking part 931 to separate from the second female locking part 651, allowing the locking member 93 to be removed from the locking part 65, which can improve the ease of unlocking the locking member 93 and the locking part 65.

[0094] Please refer to Figures 1 to 7 This application provides another high-speed connector, including a socket 100.

[0095] Specifically, the socket 100 includes first signal differential pair groups 110 stacked along a first direction X. Each first signal differential pair group 110 includes a first signal differential pair 1 and a first shielding member 2. A first shielding cavity 2a is formed between the first shielding members 2 of two adjacent first signal differential pair groups 110 along the first direction X, and the first signal differential pair 1 is housed within the first shielding cavity 2a. The first direction X can be the thickness direction of the socket 100. Multiple first signal differential pair groups 110 can be provided. Multiple first signal differential pair groups 110 can be stacked along the first direction X. Each first signal differential pair group 110 includes multiple first signal differential pairs 1 and a matching first shielding member 2. The first shielding member 2 can be a one-piece stamped metal part. The cross-section of the first shielding member 2 can be U-shaped. Along the first direction X, two adjacent first shielding members 2 cooperate to jointly form the first shielding cavity 2a. Each first shielding cavity 2a can accommodate one first signal differential pair 1. Each first signal differential pair 1 is surrounded by the corresponding first shield 2 and the adjacent first shield 2 in the first direction X, thereby electrically isolating the adjacent differential channels of the socket 100, reducing electromagnetic coupling crosstalk between adjacent differential channels, and achieving electromagnetic shielding.

[0096] The first shielding component 2 has a first shielding contact area 20, and the first signal differential pair 1 has a first signal contact area 10. When the plug 200 and the socket 100 are mated, the first shielding contact area 20 and the shielding component of the plug 200 are configured to conduct before the first signal contact area 10 and the signal differential pair of the plug 200. Specifically, the first shielding contact area 20 can be formed on the front end of the first shielding component 2, and the front ends of the first shielding contact area 20 and the shielding structure of the plug 200 are in contact with each other to achieve electrical conduction and equipotential grounding. The first signal contact area 10 is formed on the front end of the first signal differential pair 1, and the front ends of the first signal contact area 10 and the signal differential pair of the plug 200 are in contact with each other to form a differential signal transmission path.

[0097] When the plug 200 and socket 100 are mated, the first shielding contact area 20 of the first shield 2 establishes an electrical connection with the shielding structure of the plug 200, forming a complete shielding loop. Subsequently, the first signal contact area 10 of the first signal differential pair 1 establishes an electrical connection with the signal differential pair of the plug 200, forming a complete signal transmission path. That is, during the mating process of the plug 200 and socket 100, the electrical connection between the first shield 2 and the shielding structure of the plug 200 takes precedence over the electrical connection between the first signal differential pair 1 and the signal differential pair of the plug 200. This allows for timing control of the grounding sequence of the plug 200 and socket 100 before the signal transmission begins, ensuring that the first signal contact area 10 is located in the first shielding cavity 2a before signal transmission starts, thereby effectively suppressing electromagnetic crosstalk. Simultaneously, it effectively prevents electrostatic discharge from damaging the first signal differential pair 1, improving the hot-plug safety of the high-speed connector.

[0098] Thus, by stacking multiple sets of first signal differential pairs 110 in the first direction X, a first shielding cavity 2a for accommodating the first signal differential pairs 1 can be formed between adjacent first shielding members 2 in the first direction X. Each set of first signal differential pairs 1 can be covered by the first shielding member 2, which can improve the shielding effect of the first signal differential pairs 1 and enhance the crosstalk suppression performance between the first signal differential pairs 1. At the same time, when the plug 200 and the socket 100 are connected, the shielding structure of the first shielding contact area 20 and the plug 200 conducts before the signal differential pairs of the first signal contact area 10 and the plug 200, realizing the priority conduction of the grounding terminal of the socket 100 and the plug 200, ensuring the shielding effect of the first signal differential pairs 1, effectively suppressing electromagnetic crosstalk between each first signal differential pair 1, which is conducive to ensuring the signal integrity of each transmission path and improving the transmission quality of high-speed signals.

[0099] Please refer to Figure 1 , Figure 2 as well as Figures 8 to 11 This application provides yet another high-speed connector, including a plug 200.

[0100] Specifically, the plug 200 includes second signal differential pair groups 220 stacked along a first direction X. Each second signal differential pair group 220 includes a second signal differential pair 3 and a second shielding member 4. A second shielding cavity 4a is formed between the second shielding members 4 of adjacent second signal differential pair groups 220 along the first direction X, and the second signal differential pair 3 is housed within the second shielding cavity 4a. The first direction X can be the thickness direction of the plug 200. Multiple second signal differential pair groups 220 can be provided. Multiple second signal differential pair groups 220 can be stacked along the first direction X. Each second signal differential pair group 220 includes multiple second signal differential pairs 3 and a matching second shielding member 4. The second shielding member 4 can be a one-piece stamped metal part. The cross-section of the second shielding member 4 can be U-shaped. Along the first direction X, adjacent second shielding members 4 cooperate to jointly form a second shielding cavity 4a. Each second shielding cavity 4a can accommodate one second signal differential pair 3. Each second signal differential pair 3 is surrounded by the corresponding second shield 4 and the adjacent second shield 4 in the first direction X, thereby electrically isolating the adjacent differential channels of the plug 200, reducing electromagnetic coupling crosstalk between adjacent differential channels, and achieving electromagnetic shielding.

[0101] The second shielding component 4 has a second shielding contact area 40, and the second signal differential pair 3 has a second signal contact area 30. When the plug 200 mates with the socket 100, the second shielding contact area 40 and the shielding component of the socket 100 are configured to conduct before the second signal contact area 30 and the signal differential pair of the socket 100. Specifically, the second shielding contact area 40 can be formed on the front end of the second shielding component 4, and the front end of the second shielding contact area 40 and the shielding structure of the socket 100 are in contact with each other to achieve electrical conduction and equipotential grounding. The second signal contact area 30 is formed on the front end of the second signal differential pair 3, and the front end of the second signal contact area 30 and the signal differential pair of the socket 100 are in contact with each other to form a differential signal transmission path.

[0102] When the plug 200 and socket 100 are mated, the second shielding contact area 40 of the second shield 4 establishes an electrical connection with the shielding structure of the socket 100, forming a complete shielding loop. Subsequently, the second signal contact area 30 of the second signal differential pair 3 establishes an electrical connection with the signal differential pair of the socket 100, forming a complete signal transmission path. That is, during the mating process of the plug 200 and socket 100, the electrical connection between the second shield 4 and the shielding structure of the socket 100 takes precedence over the electrical connection between the second signal differential pair 3 and the signal differential pair of the socket 100. This allows for timing control of the grounding sequence of the plug 200 and socket 100 before the signal transmission begins, ensuring that the second signal contact area 30 is located in the second shielding cavity 4a before signal transmission starts, thereby effectively suppressing electromagnetic crosstalk. Simultaneously, it effectively prevents electrostatic discharge from damaging the second signal differential pair 3, improving the hot-plug safety of the high-speed connector.

[0103] Thus, multiple sets of second signal differential pairs 220 are stacked in the first direction X. In the first direction X, a second shielding cavity 4a for accommodating the second signal differential pairs 3 can be formed between adjacent second shielding members 4. Each set of second signal differential pairs 3 can be covered by the second shielding member 4, improving the shielding effect of the second signal differential pairs 3 and enhancing the crosstalk suppression performance between the second signal differential pairs 3. Simultaneously, when the plug 200 and socket 100 are connected, the shielding structure of the second shielding contact area 40 and the plug 200 conducts before the signal differential pairs of the second signal contact area 30 and the socket 100, achieving priority conduction of the grounding terminals of the socket 100 and the plug 200. This ensures the shielding effect of the second signal differential pairs 3, effectively suppresses electromagnetic crosstalk between the second signal differential pairs 3, helps ensure the signal integrity of each transmission path, and improves the transmission quality of high-speed signals.
