[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. During high-speed signal transmission, electrical signal connectors are susceptible to electromagnetic interference, which can not only cause signal distortion but also increase the bit error rate.

[0003] Currently, high-speed differential signal connectors mostly employ the method of adding shielding plates to the differential modules to reduce mutual interference between different differential pairs. However, existing shielding structures cannot effectively shield the signal differential pairs, resulting in significant electromagnetic interference in the mating area and affecting the signal integrity of the transmission link.

[0026] 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.

[0027] Please refer to Figures 1 to 9 This application provides a high-speed connector, including a socket 100 and a plug 200. The front end of the socket 100 is a mating end for mates with the plug 200, and the front end of the plug 200 is also a mating end for mates with the socket 100. That is, the front end of the plug 200 mates with the front end of the socket 100. Furthermore, the rear end of the socket 100 is a soldering end for connection to a printed circuit board, and the rear end of the plug 200 is a soldering end for connection to a cable 90.

[0028] The socket 100 includes a first signal differential pair 1 and a first shield 2. The circumferential sidewalls of the first shield 2 are interconnected to form a cylindrical shape, and the first shield 2 covers the outer periphery of the first signal differential pair 1. The first shield 2 can be made of a metallic material. The interconnected circumferential sidewalls of the first shield 2 form a cylindrical shape, allowing the first shield 2 to completely enclose the first signal differential pair 1. The first signal differential pair 1 consists of two first signal terminals 12, used for transmitting high-speed differential signals. The first shield 2 covers the entire signal transmission path of the first signal differential pair 1, forming a continuous shield from the front end to the rear end of the first signal terminals 12.

[0029] The plug 200 is configured to mate with the socket 100. The plug 200 includes a second signal differential pair 3 and a second shield 4. The circumferential sidewalls of the second shield 4 are interconnected to form a cylindrical shape, and the second shield 4 covers the outer periphery of the second signal differential pair 3. The second shield 4 may be made of a metallic material. The interconnected circumferential sidewalls of the second shield 4 form a cylindrical shape, allowing the second shield 4 to completely enclose the second signal differential pair 3. The second signal differential pair 3 consists of two second signal terminals 32, used to mate with the first signal differential pair 1 to transmit high-speed differential signals. The second shield 4 covers the entire signal transmission path of the second signal differential pair 3, forming a continuous shield from the front end to the rear end of the second signal terminals 32.

[0030] The first shielding member 2 has a first shielding contact area 20, the second shielding member 4 has a second shielding contact area 40 for conducting 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 conducting with the first signal contact area 10. When the plug 200 is connected to the socket 100, 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.

[0031] Specifically, the first shielding contact area 20 is located at the front end of the first shielding member 2 and is used to make electrical contact with the second shielding member 4. The second shielding contact area 40 is located at the front end of the second shielding member 4 and is used to conduct with the first shielding contact area 20. The first signal contact area 10 is located at the front end of the first signal differential pair 1 and is used to make signal connection with the second signal differential pair 3. The second signal contact area 30 is located at the front end of the second signal differential pair 3 and is used to conduct with the first signal contact area 10. During the docking process between the plug 200 and the socket 100, 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. That is, when the plug 200 moves toward the socket 100, the first shielding contact area 20 and the second shielding contact area 40 first make contact with each other, the first shielding member 2 and the second shielding member 4 form a grounding path, and then the first signal contact area 10 and the second signal contact area 30 make contact with each other, and the first signal differential pair 1 and the second signal differential pair 3 begin high-speed signal transmission. Thus, by first making the first shielding contact area 20 and the second shielding contact area 40 conductive, and then making the first signal contact area 10 and the second signal contact area 30 conductive, the plug 200 and the socket 100 are connected so that grounding precedes signal connection. In this way, the plug 200 and the socket 100 can establish a shielding circuit in advance before the high-speed signal transmission begins, thereby effectively suppressing electromagnetic interference generated when the plug 200 and the socket 100 are connected.

[0032] Through the above technical solution, the first shielding component 2 and the second shielding component 4 can respectively provide full-coverage shielding for the first signal differential pair 1 and the second signal differential pair 3, thereby improving the shielding effect of the first signal differential pair 1 and the second signal differential pair 3, enhancing the crosstalk suppression performance between the first signal differential pair 1 and the second signal differential pair 3. Simultaneously, when the plug 200 and the 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 the plug 200, ensuring 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, and contributing to ensuring the signal integrity of each transmission path. Furthermore, as... Figure 10As shown, under a 56GHz 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 -50dB. Figure 11 As shown, under a 56GHz 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 -40dB, which meets the transmission requirements of high-frequency high-speed differential signals.

[0033] Please refer to Figures 6 to 9 as well as Figures 12 to 14 The first shielding contact area 20 and the second shielding contact area 40 are configured to surround the first signal contact area 10 and the second signal contact area 30 when the plug 200 is mated with the socket 100.

[0034] Specifically, when the plug 200 is connected to the socket 100, the first shielding contact area 20 and the second shielding contact area 40 overlap to form a continuous rectangular shield. This rectangular shield completely surrounds the first signal contact area 10 and the second signal contact area 30. That is, after the plug 200 is connected to the socket 100, the first signal contact area 10 and the second signal contact area 30 are located inside the shielding cavity formed by the first shielding contact area 20 and the second shielding contact area 40. The cooperation of the first shielding contact area 20 and the second shielding contact area 40 reduces external electromagnetic interference entering the shielding cavity, preventing interference with signal transmission between the first signal contact area 10 and the second signal contact area 30. Simultaneously, the shielding cavity formed by the first shielding contact area 20 and the second shielding contact area 40 absorbs and reflects electromagnetic waves radiated outward from the internal first signal contact area 10 and the second signal contact area 30, reducing interference with signal transmission between other first signal differential pairs 1 and 3.

[0035] Thus, through the cooperation of the first shielding contact area 20 and the second shielding contact area 40, a circumferential full-coverage shielding of the first signal contact area 10 and the second signal contact area 30 can be formed, which can enhance the anti-crosstalk capability of the mating areas of the first signal differential pair 1 and the second signal differential pair 3, realize the complete coverage of the mating areas of the first signal differential pair 1 and the second signal differential pair 3, improve the shielding performance of the entire signal transmission link of the high-speed connector, and thus enable the high-speed connector to maintain an extremely low crosstalk level at a frequency of 60GHz.

[0036] Please refer to Figures 6 to 9 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 closer to the first main body 21 relative to the front end of the stepped part 22.

[0037] Specifically, the first main body 21 can be configured as a rectangular or approximately rectangular cylindrical structure. The first main body 21 is used to enclose the main body portion of the first signal differential pair 1. A stepped portion 22 is disposed at the front end of the first main body 21, and the stepped portion 22 protrudes forward relative to the first main body 21. The stepped portion 22 and the first main body 21 are an integral structure. The stepped portion 22 can be formed on the front end of a portion of the side wall of the first main body 21, and the front end face of the stepped portion 22 is further forward than the front end face of the first main body 21. At the same time, the outer side wall of the stepped portion 22 is flush with the outer side wall of the first main body 21, and the stepped portion 22 is located on both sides of the first signal terminal 12, that is, the stepped portion 22 separates the first signal terminal 12 from the outside from both sides.

[0038] Furthermore, the front end of the first signal differential pair 1 is closer to the front end of the step portion 22 than the front end of the first main body portion 21. That is, the front end face of the step portion 22 protrudes more than the front end face of the first signal differential pair 1. Thus, by setting the step portion 22, when the plug 200 is connected to the socket 100, the step portion 22 and the second shield 4 make contact before the first signal differential pair 1 and the second signal differential pair 3, which mechanically ensures the reliability of the first shield contact area 20 and the second shield contact area 40 being preferentially grounded, while simplifying the grounding structure of the first shield 2 and the second shield 4, eliminating the need for a complex mechanical linkage mechanism.

[0039] Please refer to Figures 6 to 9 The first shielding contact area 20 includes a first shielding sidewall 201, a first shielding top wall 202, and a first shielding bottom spring piece 203. The first shielding sidewall 201 is formed on the stepped portion 22, the first shielding top wall 202 is formed on the front end of the top wall of the first shielding member 2, and the first shielding bottom spring piece 203 is formed on the front end of the bottom wall of the first shielding member 2. Specifically, the first shielding sidewall 201 can be formed on the left and right sidewalls of the stepped portion 22. In practical applications, the first shielding sidewall 201 can specifically be the front end portion of the transverse sidewalls of the stepped portion 22. The first shielding top wall 202 is formed on the front end of the top wall of the first shielding member 2, that is, the first shielding top wall 202 is formed on the front end portion of the top wall of the first main body portion 21. In practical applications, since the stepped portion 22 is formed on the front end of the first main body portion 21, the first shielding top wall 202 can be the front end portion of the top wall of the stepped portion 22. The first shielding bottom spring 203 is formed at the front end of the bottom wall of the first shielding member 2, that is, the first shielding bottom spring 203 is formed at the front end of the bottom wall of the first main body 21 and extends forward and upward to form a cantilever spring structure. The first shielding bottom spring 203 has a certain elasticity and can elastically abut against the corresponding part of the second shielding member 4 when the plug 200 and the socket 100 are connected.

[0040] The second shielding contact area 40 includes a second shielding side spring 401, a second shielding top spring 402, and a second shielding bottom wall 403. The second shielding side spring 401 is formed at the front end of the side wall of the second shielding member 4, the second shielding top spring 402 is formed at the front end of the top wall of the second shielding member 4, and the second shielding bottom wall 403 is formed at the front end of the bottom wall of the second shielding member 4. Specifically, the second shielding side spring 401 is formed at the front ends of the left and right side walls of the second shielding member 4, that is, the second shielding side 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 second shielding top spring 402 is formed at the front end of the top wall of the second shielding member 4, and is a cantilever spring structure extending forward and downward from the front end of the top wall of the second shielding member 4. The second shielding bottom wall 403 is formed at the front end of the bottom wall of the second shielding member 4, that is, the second shielding bottom wall 403 can be the front end portion of the bottom wall of the second shielding member 4. The second shielding side spring 401 and the second shielding top spring 402 both have a certain degree of elasticity, and can elastically abut against the corresponding part of the first shielding component 2 when the plug 200 and the socket 100 are connected.

[0041] The first shielding sidewall 201 is used to connect with the second shielding side spring 401, the first shielding top wall 202 is used to connect with the second shielding top spring 402, and the first shielding bottom spring 203 is used to connect with the second shielding bottom wall 403. Specifically, when the plug 200 is mated with the socket 100, the second shielding side spring 401 can elastically press against the outer or inner surface of the first shielding sidewall 201 to achieve lateral electrical contact between the first shielding component 2 and the second shielding component 4. The second shielding top spring 402 can elastically press against the upper or lower surface of the first shielding top wall 202 to achieve electrical contact between the top of the first shielding component 2 and the second shielding component 4. The first shielding bottom spring 203 can elastically press against the lower or upper surface of the second shielding bottom wall 403 to achieve electrical contact between the bottom of the first shielding component 2 and the second shielding component 4.

[0042] It should be noted that, in this embodiment, when the plug 200 and the socket 100 are connected, the first shielding bottom spring 203 can elastically press against the lower surface of the second shielding bottom wall 403, the second shielding side spring 401 can elastically press against the inner surface of the first shielding side wall 201, and the second shielding top spring 402 can elastically press against the upper surface of the first shielding top wall 202.

[0043] Thus, through the elastic abutment and engagement of the first shielding sidewall 201 and the second shielding side spring 401, the first shielding top wall 202 and the second shielding top spring 402, and the first shielding bottom spring 203 and the second shielding bottom wall 403, reliable conductive paths can be formed in all four circumferential directions for the first shielding contact area 20 and the second shielding contact area 40, ensuring the continuity and low impedance of the shielding. Furthermore, the elastic pressing connection between the first shielding contact area 20 and the second shielding contact area 40 allows for certain manufacturing tolerances and mating offsets in the first shielding component 2 and the second shielding component 4, which helps improve the fault tolerance and reliability of the connection between the first shielding component 2 and the second shielding component 4.

[0044] Please refer to Figures 6 to 9 as well as Figure 14 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 soldering to the signal circuit of a 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.

[0045] The first signal contact area 10 can 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.

[0046] The second signal differential pair 3 includes a second encapsulation 31 and a second signal terminal 32 embedded within the second encapsulation 31. The front end of the second signal terminal 32 extends from the front end 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 may be made of insulating plastic. The second encapsulation 31 may be manufactured by processes including but not limited to injection molding. The second encapsulation 31 may completely cover the rear end portion of the second signal terminal 32, allowing the front end portion of the second signal terminal 32 to extend from the front end of the second encapsulation 31. Each second signal differential pair 3 includes two second signal terminals 32 arranged side by side. The second signal terminal 32 is in the form of an elongated metal conductive strip. The front end portion of the second signal terminal 32 extending from the front end of the second encapsulation 31 forms the second signal contact area 30. The rear end of the second signal terminal 32 is in communication with the core wire end of the cable 90. 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] Please refer to Figure 4 , Figure 5 as well as Figures 14 to 17The 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.

[0051] The first molding compound 11 has a first sub-engagement portion 111, and the first shielding member 2 has a first female engagement portion 211. The first sub-engagement portion 111 is configured to engage with the first female engagement portion 211. Specifically, the first sub-engagement portion 111 can be either a slot or a block, and the first female engagement portion 211 can be either a slot or a block. The slot and block structures are mutually compatible. The first sub-engagement portion 111 can be located at the top and bottom of the first molding compound 11. Correspondingly, the first female engagement portion 211 is located at the top and bottom of the first shielding member 2. Thus, when the first molding compound 11 and the first shielding member 2 are assembled, the first sub-engagement portion 111 and the first female engagement portion 211 engage and lock together, preventing axial movement of the first molding compound 11 and the first shielding member 2 and ensuring the structural stability of the first signal differential pair 1.

[0052] The first molding compound 11 has a first sub-stop 112, and the first shielding member 2 has a first female stop 212. The first sub-stop 112 is disposed within the first female stop 212. Specifically, the first sub-stop 112 can be one of a stop block and a groove, and the first female stop 212 can be the other of a stop block and a groove. The structures of the stop block and the groove are mutually compatible. The first sub-stop 112 can be disposed on the side wall of the first molding compound 11. Correspondingly, the first female stop 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 first sub-stop 112 enters the first female stop 212. When the first molding compound 11 and the first shielding member 2 are installed in place, the first female stop 212 can abut against the first sub-stop 112 and continue to move forward, thereby axially defining the position of the first molding compound 11 within the first shielding member 2.

[0053] It should be noted that, since the first sub-clamping part 111 and the first female clamping part 211 are connected by a snap-fit, the clamping blocks in the first sub-clamping part 111 and the first female clamping part 211 have a beveled structure in the assembly direction, allowing the clamping blocks to smoothly enter the clamping slot. Because the clamping blocks have a beveled structure in the assembly direction, the connection strength between the first molding compound 11 and the first shielding member 2 in the assembly direction will be reduced to some extent. To solve this problem, the cooperation of the first sub-stopping part 112 and the first female stopping part 212 can restrict the position of the first molding compound 11 within the first shielding member 2, preventing the first molding compound 11 from continuing to move relative to the first shielding member 2 in the assembly direction. This helps ensure the precise assembly and stable connection between the first shielding member 2 and the first molding compound 11, preventing relative displacement or even detachment of the first shielding member 2 and the first molding compound 11 during the assembly of the first signal differential pair 1.

[0054] Please refer to Figure 4 , Figure 5 as well as Figures 14 to 17 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 insert 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.

[0055] A stop protrusion 51 is formed on the inner wall of the first channel 501, which is used to limit the stepped portion 22. 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 shield 2. Specifically, when the first shield 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 shield 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.

[0056] 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 restricts the position of the first shielding member 2 within the first channel 501, preventing further movement in the assembly direction. This helps ensure precise assembly and stable connection between the first shielding member 2 and the first molding compound 11, improving the stability of the first signal differential pair 1 within the first channel 501.

[0057] 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.

[0058] 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 different rows of the first signal differential pair 1 in the socket 100 can be adaptively modified. For example... Figure 7 and Figure 8 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 1, so as to match the structure of the signal circuit on the printed circuit board and enhance the structural adaptability of the socket 100.

[0059] Please refer to Figures 1 to 5as well as Figures 12 to 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 1, but also provides additional electromagnetic shielding for the inner first signal differential pair 1.

[0060] 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.

[0061] The first base 5 is provided with a second sub-stop portion 52, and the first housing 6 is provided with a second female stop portion 62, with the second sub-stop portion 52 disposed within the second female stop portion 62. Specifically, the second sub-stop portion 52 can be one of a stop block and a groove, and the second female stop portion 62 can be the other of a stop block and a groove. The stop block and the groove have matching structures. The stop block can be a T-shaped structure. Thus, when the first housing 6 is fitted onto the first base 5, the second sub-stop portion 52, disposed within the second female stop portion 62, forms a limiting engagement, 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.

[0062] It should be noted that the first housing 6 and the first base 5 can be locked in the first housing 6 in the front-rear direction by the cooperation of the second folding part 61 with the second male stop part 52 and the second female stop part 62, so as to prevent the first base 5 from coming out of the first housing 6 and achieve a stable connection between the first housing 6 and the first base 5.

[0063] In this embodiment, a guide slot 53 may be provided on the top of the first base 5. The guide slot 53 may be an L-shaped slot structure. A guide arm 65 may be provided on the top of the first housing 6. The guide arm 65 may be an L-shaped plate structure. When assembling the first base 5 and the first housing 6, the guide arm 65 can be inserted from the top opening of the guide slot 53. Through the cooperation of the guide arm 65 and the guide slot 53, the assembly process of the first housing 6 and the first base 5 can be guided, so that the second female stop part 62 and the second female stop part 52 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.

[0064] The front end of the first housing 6 is provided with a first guide portion 63, which is configured to guide the plug 200 to mate with the socket 100. Specifically, the first guide portion 63 can be a flared edge that folds outward from the front edge of the first housing 6, or it can be a flared guide surface. The first guide portion 63 is configured to guide the plug 200 to mate with the socket 100. That is, when the plug 200 and the socket 100 are mated, the plug 200 can contact the first guide portion 63 first. The first guide portion 63 can guide the front end of the plug 200 to a position directly opposite the socket 100, so that each of the first signal differential pairs 1 of the plug 200 can conduct with the second signal differential pairs 3 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 pairs 1, the second signal differential pairs 3, the first shield 2, and the second shield 4 due to misalignment of the plug 200 and the socket 100.

[0065] Please refer to Figure 8 , Figure 9 , Figure 13 , Figure 14 and Figure 19 The second molding compound 31 includes a front molding compound 311 and a rear molding compound 312 connected to each other. The front molding compound 311 has a first sub-positioning part 3111, and the rear molding compound 312 has a first female positioning part 3121 adapted to the first sub-positioning part 3111. The first sub-positioning part 3111 is connected to the first female positioning part 3121.

[0066] Specifically, the front encapsulation 311 can be used to fix the front end portion of the second signal terminal 32. The front encapsulation 311 can maintain the spacing between the front end portions of the two second signal terminals 32, thereby enabling accurate mating with the two first signal terminals 12 corresponding to the first signal differential pair 1. The rear encapsulation 312 can be used to fix the rear end portion of the second signal terminal 32 and the core wire end of the cable 90. The front encapsulation 311 and the rear encapsulation 312 can be two independent components that are injection molded sequentially. Specifically, the front encapsulation 311 and the rear encapsulation 312 sequentially cover the front end and rear end of the second signal terminal 32 through an injection molding process, respectively. The front encapsulation 311 and the rear encapsulation 312 are interconnected.

[0067] It should be noted that, in this embodiment, the order in which the front molding body 311 and the rear molding body 312 are injection molded is not specifically limited.

[0068] Furthermore, a first sub-positioning portion 3111 is formed on the rear end face of the front molded body 311. The first sub-positioning portion 3111 can be in the form of, but is not limited to, a limiting groove. During the injection molding process of the rear molded body 312, a first female positioning portion 3121 is formed at the first sub-positioning portion 3111 of the front molded body 311. The first female positioning portion 3121 can be in the form of a limiting block adapted to the limiting groove. Through the cooperation of the first sub-positioning portion 3111 and the first female positioning portion 3121, the connection strength and connection reliability between the front molded body 311 and the rear molded body 312 can be improved.

[0069] Thus, by configuring the second molding compound 31 into two sections, a front molding compound 311 and a rear molding compound 312, the front and rear portions of the second signal terminal 32 can be molded separately. This facilitates the separate injection molding of the rear molding compound 312 when the rear portion of the second signal terminal 32 is soldered to the core wire of the cable 90, which to some extent reduces the molding difficulty of the second molding compound 31 and improves the assembly flexibility of the plug 200. At the same time, the cooperation of the first sub-positioning part 3111 and the first female positioning part 3121 can improve the structural strength of the front molding compound 311 and the rear molding compound 312, preventing them from twisting or shifting under external forces.

[0070] Please refer to Figure 6 , Figure 9 and Figure 19 The second shield 4 is provided with an overlap portion 41, and a shield 42 is provided on the outside of the overlap portion 41. The shield 42 is configured to fix the overlap portion 41 to the shield layer 901 of the cable 90 and realize electrical connection.

[0071] Specifically, the overlapping portion 41 can be a metal sheet structure arranged from the rear end of the second shield 4 toward the cable 90. The overlapping portion 41 can include multiple overlapping portions, which are spaced apart from each other. The multiple overlapping portions 41 can overlap the shielding layer 901 along the circumference of the cable 90, thereby realizing the electrical connection between the second shield 4 and the shielding layer 901 of the cable 90.

[0072] Furthermore, a shielding cover 42 may be provided on the outside of the overlap portion 41. The shielding cover 42 may be a separate metal component. The shielding cover 42 may be a sleeve-shaped structure formed by bending a metal sheet. The shielding cover 42 is configured to fix the overlap portion 41 to the shielding layer 901 of the cable 90 and achieve electrical connection. Specifically, the outer sheath of the cable 90 near the plug 200 may be stripped first to expose the shielding layer 901. Then, the overlap portion 41 of the second shielding member 4 is fitted onto the outer periphery of the cable 90, so that the inner surface of the overlap portion 41 contacts the shielding layer 901. Finally, the metal sheet is bent around the circumference of the cable 90 and wrapped around the outside of the multiple overlapping parts 41. The two sides of the metal sheet can be welded and fixed, so that while forming the shielding cover 42, the overlapping parts 41 and the shielding layer 901 can be connected and fixed, so that the shielding cover 42 and the second shielding component 4 and the shielding layer 901 of the cable 90 are tightly fitted, thereby forming a continuous grounding path between the plug 200 and the cable 90.

[0073] Thus, through the cooperation of the overlapping part 41 and the shielding cover 42, the second shielding component 4 can be made conductive with the shielding layer 901 of the cable 90, improving the connection reliability between the second shielding component 4 and the shielding layer 901 of the cable 90. Subsequently, when the plug 200 and the socket 100 are connected, they can work together with the first shielding component 2 to form a grounding path from the cable 90 to the printed circuit board, thereby achieving full shielding of the entire transmission link and further improving the crosstalk resistance of the high-speed connector.

[0074] In this embodiment, the metal sheet used to form the shield 42 has multiple tooth-like structures between its two side edges, and these tooth-like structures can be staggered. The multiple staggered tooth-like structures can guide the metal sheet when it is pressed together to form the metal shield, preventing the metal shield from shifting when it is pressed onto the overlap 41. This helps to improve the welding strength of the shield 42 and ensures the reliability of the connection between the overlap 41 and the shielding layer 901.

[0075] It should be noted that the rear end of the second shielding component 4 has a back plate 44. The back plate 44, as part of the second shielding component 4, can be fixedly connected to the main body of the second shielding component 4 by welding. The structure of the second encapsulation body 31, composed of a front encapsulation body 311 and a rear encapsulation body 312, can be approximately L-shaped. During the assembly process of the second encapsulation body 31 and the second shielding component 4, the front encapsulation body 311 of the second encapsulation body 31 can be inserted into the main body of the second shielding component 4 from the rear end. Subsequently, the back plate 44 is placed at the rear end of the main body of the second shielding component 4 and fixed at the rear end of the main body of the second shielding component 4 by welding, thereby fixing the second encapsulation body 31 inside the second shielding component 4.

[0076] Please refer to Figures 20 to 23 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. The second signal differential pair 3 can be fixed within the second channel 701 by a second shield 4. 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.

[0077] The second molding compound 31 has a fourth sub-engagement portion 3122, and the second shielding member 4 has a fourth female engagement portion 43. The fourth sub-engagement portion 3122 is configured to engage with the fourth female engagement portion 43. Specifically, the fourth sub-engagement portion 3122 can be either a locking block or a locking slot, and the fourth female engagement portion 43 can be either a locking block or a locking slot. In practical applications, the fourth sub-engagement portion 3122 can be located on the side wall of the rear molding compound 312. Thus, when the second molding compound 31 and the second shielding member 4 are assembled, the fourth sub-engagement portion 3122 and the fourth female engagement portion 43 engage and lock together, preventing axial movement of the second molding compound 31 and the second shielding member 4 and ensuring the structural stability of the second signal differential pair 3.

[0078] It should be noted that, since the fourth sub-clamping part 3122 and the fourth female clamping part 43 are connected by a snap-fit, the clamping blocks in the fourth sub-clamping part 3122 and the fourth female clamping part 43 have an inclined structure in the assembly direction, allowing the clamping blocks to smoothly enter the clamping slot. Because the clamping blocks have an inclined structure in the assembly direction, this will, to some extent, reduce the connection strength of the second molding compound 31 and the second shielding member 4 in the assembly direction. Meanwhile, the structure of the second molding compound 31, which is composed of the front molding compound 311 and the rear molding compound 312, can be roughly L-shaped. When the front molding compound 311 at the front end of the second molding compound 31 is inserted into the second shield 4 from the rear end of the second shield 4, the rear molding compound 312 at the rear end of the second molding compound 31 can restrict the position of the second molding compound 31 in the second shield 4, preventing the second molding compound 31 from continuing to move relative to the first shield 2 in the assembly direction. This helps to ensure the accurate assembly and stable connection between the second shield 4 and the second molding compound 31, and prevents the second signal differential pair 3 from being displaced or even falling off relative to the second shield 4 and the second molding compound 31 during the assembly process.

[0079] Please refer to Figures 1 to 5 , Figure 13 , Figure 20 and Figure 22 The plug 200 also includes a second housing 8, which is disposed at the rear end of the second base 7. A second sub-positioning portion 81 is formed on the top of the second housing 8, and a second female positioning portion 71 adapted to the second sub-positioning portion 81 is formed on the top of the second base 7. Specifically, the second housing 8, as the outer metal shell of the plug 200, can be made of sheet metal by stamping. After the second signal differential pair 3 and the second shield 4 are 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.

[0080] The second sub-positioning part 81 can be one of a positioning block and a positioning groove, and the second female positioning part 71 can be the other of a positioning block and a positioning groove. The second sub-positioning part 81 can be disposed on the top of the second base 7. The second female positioning part 71 can be disposed on the top of the second housing 8. The positioning block and the positioning groove are mutually adapted.

[0081] Furthermore, the second housing 8 has a third sub-engagement portion 82, the second base 7 has a third female engagement portion 72, and the second base 7 has an assembly groove 73. The third sub-engagement portion 82 is configured to pass through the assembly groove 73 and engage with the third female engagement portion 72, thereby allowing the second sub-positioning portion 81 to engage with the second female positioning portion 71. Specifically, both the third sub-engagement portion 82 and the third female engagement portion 72 are in the form of elastic hooks, and they are mutually compatible. The third sub-engagement portion 82 is formed on the side wall of the second housing 8. The third female engagement portion 72 is formed on the side wall of the second base 7. The assembly groove 73 is also formed on the side wall of the second base 7, and the assembly groove 73 is used to avoid the third sub-engagement portion 82.

[0082] During the assembly of the second housing 8 and the second base 7, the third sub-clamping part 82 is aligned with the assembly groove 73, and the second housing 8 is moved from the rear end to the front end of the second base 7 until the third sub-clamping part 82 passes through the assembly groove 73. Subsequently, the second housing 8 is moved from top to bottom, causing the third sub-clamping part 82 to engage with the third female clamping part 72, while the second sub-positioning part 81 engages with the second female positioning part 71. Thus, by having the third sub-clamping part 82 pass through the assembly groove 73 first, and then moving the second housing 8 up and down to achieve the engagement of the third sub-clamping part 82 and the third female clamping part 72, the installation process between the second housing 8 and the second base 7 can be completed without complex tools, making it easier to automate the assembly of the plug 200. Furthermore, the precise alignment between the second housing 8 and the second base 7 is ensured through the cooperation of the second sub-positioning part 81 and the second female positioning part 71, as well as the dual function of the third sub-clamping part 82 and the third female clamping part 72.

[0083] Please refer to Figure 4 , Figure 5 , Figure 13 and Figure 19 The plug 200 also includes an isolator 91 disposed between the second housing 8 and the second base 7, the isolator 91 being configured to isolate adjacent cables 90.

[0084] 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 hold a corresponding cable 90, thus separating multiple cables 90 and preventing them from shifting between the second base 7 and the second housing 8. In practical applications, each cable 90 extends from the rear end of the second encapsulation body 31 and passes sequentially through the corresponding grooves on both sides of the isolator 91. The cooperation of the second housing 8 and the second base 7 covers and fixes the multiple cables 90 on both sides of the isolator 91, preventing shifting between different cables 90. Thus, the isolator 91 prevents contact or crossing between adjacent cables 90. During the secondary encapsulation process, the isolator 91 can fix the position of the cables 90, preventing them from shifting due to the flow of molten plastic, thereby improving the reliability of the cable 90 position in the plug 200 and ensuring stable signal transmission in the plug 200.

[0085] Please refer to Figure 4 , Figure 5 , Figure 13 and Figure 19 The plug 200 also includes a filler 92 disposed between the second housing 8 and the second base 7, the filler 92 being configured to encapsulate the isolated cable 90.

[0086] Specifically, the filler 92 can be made of insulating encapsulating material. At least one injection hole is formed on both the second base 7 and the second housing 8. After the cable 90 is positioned by the isolator 91, the second housing 8 is assembled at the rear end of the second base 7. Subsequently, liquid insulating plastic material can be injected between the second base 7 and the second housing 8 through the injection hole using low-pressure injection molding or potting processes. The liquid insulating plastic material can fill the area near the isolator 91, and after the insulating plastic material cures, it forms the filler 92. Thus, the filler 92 not only works with the isolator 91 to ensure reliable positioning of the cable 90, but also completely encapsulates the welding area of ​​the shielding cover 42, the overlap 41, and the shielding layer 901, improving the connection reliability between the second shielding component 4 and the shielding layer 901 of the cable 90. Furthermore, it can fix the cable 90 between the second base 7 and the second housing 8, increasing the tensile strength of the cable 90.

[0087] Please refer to Figures 1 to 5 as well as Figure 13 , Figure 15 , Figure 20 and Figure 22The plug 200 also includes a locking member 93, which is disposed on the second base 7. The first housing 6 has a locking part 64, and the locking member 93 is inserted into the locking part 64. The locking member 93 has a fifth sub-engagement part 931, and the locking part 64 has a fifth female engagement part 641. The fifth sub-engagement part 931 is configured to engage with the fifth female engagement part 641.

[0088] 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 a certain tensile force. Correspondingly, the first housing 6 has a locking part 64. The locking part 64 can be a lock hole structure protruding outward from the side wall of the first housing 6. The locking part 64 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 64.

[0089] The locking member 93 has a fifth sub-engagement 931 at its front end, and the locking member 64 has a fifth female engagement 641. The fifth sub-engagement 931 is one of a locking block and a locking slot, and the fifth female engagement 641 is the other of a locking block and a locking slot. When the plug 200 is fully engaged with the socket 100, operating the locking member 93 can engage the fifth sub-engagement 931 with the fifth female engagement 641, thereby locking the plug 200 onto the socket 100 and preventing the plug 200 from accidentally separating from the socket 100.

[0090] 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 64. 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 fifth female latching part 931 to separate from the fifth female latching part 641, allowing the locking member 93 to be removed from the locking part 64, which can improve the ease of unlocking the locking member 93 and the locking part 64.
