[0007] In one embodiment of this application, the female shielding assembly includes side shielding members respectively disposed on both sides of the female differential signal terminal in the horizontal direction, and each first female grounding member is disposed on the corresponding side shielding member.

[0008] In one embodiment of this application, the connector system has a height direction perpendicular to the mating direction; the female grounding element includes a second female grounding element disposed on at least one side of the female differential signal terminal in the height direction.

[0011] In one embodiment of this application, the connector system has a height direction perpendicular to the mating direction; the male connector further includes a male grounding member disposed on at least one side of the male differential signal terminal in the height direction, the male grounding member being used to electrically connect with the female shielding assembly when the female connector and the male connector are mated together.

[0012] In one embodiment of this application, one of the at least two grounding terminals is an elastic contact, and the other grounding terminal is an elastic sliding contact; the elastic sliding contact can contact the male shielding component when the female connector and the male connector are mated together and slide in the same direction as the mating action.

[0013] In one embodiment of this application, the male connector further includes a male grounding member disposed on the male shielding assembly, the male grounding member including a grounding protrusion; the grounding protrusion is used to electrically connect with the female shielding assembly when the female connector and the male connector are mated together.

[0014] In one embodiment of this application, the connector system has a horizontal direction perpendicular to the mating direction; the male shielding assembly includes a shielding body, a base, and a plurality of elastic bodies connected to the base. The shielding body and the base cooperate to form a cavity for accommodating the male differential signal terminal.

Detailed Implementation

[0022] 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.

[0023] The parameter scale of large-scale AI models has exceeded trillions, and the size of GPU clusters has expanded from thousands of GPUs to hundreds of thousands. Against this backdrop, the interconnect bandwidth between GPUs has become a key factor restricting the release of computing power. Current mainstream 112Gbps high-speed connector products are gradually approaching their performance limits in terms of data transmission rates, making it difficult to meet the ever-increasing bandwidth demands. Therefore, the industry is working on developing 224Gbps transmission products, aiming to double the data transmission rate, thereby effectively reducing data transmission latency and supporting large-scale scientific simulations and real-time AI responses.

[0024] However, the development of 224Gbps high-speed products faces severe technical challenges. At this rate, the signal frequency bandwidth is approaching the 50GHz~60GHz band. When the length of physical structures such as traces or vias in high-speed links approaches one-quarter of the signal wavelength, these structures no longer exhibit the transmission characteristics of ideal conductors and will produce resonant antenna effects. Signals will be strongly reflected at these nodes, resulting in significant return loss and even standing wave interference, severely degrading signal transmission quality.

[0025] For connector mating interfaces, as signal frequencies increase to the aforementioned bands, impedance abrupt changes at the mating interface have become a major bottleneck restricting performance improvement. To suppress the adverse effects of inherent impedance changes, designers are forced to introduce complex impedance compensation topologies within a narrow pitch of less than 1.5mm. This results in extremely complex connector mating interface structural designs, significantly increasing manufacturing difficulty and cost.

[0026] Furthermore, 224Gbps high-speed transmission also faces severe electromagnetic interference problems. On the one hand, electromagnetic coupling effects exist between adjacent signal cables, generating far-end crosstalk; on the other hand, signals can form unintended ground loop coupling paths through connector housings and metal shielding covers, causing panel crosstalk. The coupling mechanism of this type of panel crosstalk is more complex and difficult to suppress using conventional design methods.

[0027] To address the aforementioned high-frequency resonance effects and various crosstalk coupling problems, traditional techniques, such as increasing the spacing between signal terminals or increasing the number of ground wires, are no longer effective in eliminating the signal integrity degradation caused by resonant antenna effects and complex ground loop coupling. Therefore, embodiments of this application provide a connector system and a female connector to fundamentally solve the performance bottlenecks in high-frequency signal transmission.

[0028] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an embodiment of the connector system of this application.

[0029] In one embodiment, the connector system 10 includes a female connector 20 and a male connector 30 capable of mating with each other in the mating direction X. For example... Figure 2 and Figure 3 As shown, the female connector 20 includes a female differential signal terminal 21, a female shielding assembly 22, and a female grounding component 23. Figure 4 As shown, the male connector 30 includes a male differential signal terminal 31 and a male shielding component 32.

[0030] The female shielding assembly 22 is electrically connected to the female grounding component 23. The female grounding component 23 has at least two grounding terminals 231 arranged at intervals along the mating direction X, such as... Figure 3 As shown. The at least two grounding terminals 231 may include two grounding terminals 231, or three, four or more grounding terminals 231, the specific number of which can be determined according to the number of grounding boundaries required in the actual application scenario. It can be understood that the more grounding terminals 231 there are, the more finely the segmentation of the physical structure along the mating direction X will be defined.

[0031] When the female connector 20 and male connector 30 are mated together, the female differential signal terminal 21 and the male differential signal terminal 31 are electrically connected to achieve differential signal transmission. Simultaneously, the aforementioned at least two grounding terminals 231 are electrically connected to the male shielding component 32. These at least two grounding terminals 231 are located at the front and rear sides of the signal transmission path of the female differential signal terminal 21, respectively, thus achieving grounding at the front and rear ends of the signal transmission path. The physical structure surrounding the female differential signal terminal 21 along the mating direction X is defined by these at least two grounding terminals 231, disrupting the formation conditions of the resonant cavity. This reduces the risk of insertion loss resonance at specific frequency points, thus helping to ensure the integrity of signal transmission.

[0032] In one embodiment, there are multiple female grounding elements 23, which are arranged at intervals along the outer periphery of the female differential signal terminal 21. These multiple female grounding elements 23, arranged around the outer periphery of the female differential signal terminal 21, form multiple grounding paths around the periphery of the female differential signal terminal 21. The return current during differential signal transmission can return along these multiple grounding paths. The shortened length of the return path helps reduce loop inductance and suppress common-mode radiation and electromagnetic interference.

[0033] Please refer to the following: Figure 5 , Figure 5 yes Figure 1 The diagram shows a cross-sectional view of the connector system along the AA direction.

[0034] In one embodiment, the connector system 10 has a horizontal direction Y perpendicular to the mating direction X. The female grounding element 23 includes first female grounding elements 23a respectively disposed on both sides of the female differential signal terminal 21 in the horizontal direction Y. When the female connector 20 and the male connector 30 are mated together, the first female grounding elements 23a on both sides of the horizontal direction Y are electrically connected to the male shielding component 32. The first female grounding elements 23a are also electrically connected to the female shielding component 22. The first female grounding elements 23a on both sides form grounding paths on both horizontal sides of the female differential signal terminal 21, allowing the return current during differential signal transmission to return along the grounding paths on both sides. The shortened return path length helps reduce loop inductance and suppress common-mode radiation and electromagnetic interference.

[0035] Figure 2 and Figure 5An exemplary illustration shows that two first female grounding elements 23a are provided on each side of the female differential signal terminal 21 in the horizontal direction Y, i.e., the number of first female grounding elements 23a is two, located on the left and right sides of the female differential signal terminal 21, respectively. It is understood that, depending on actual needs, multiple first female grounding elements 23a can also be provided on each side of the female differential signal terminal 21, such as two first female grounding elements 23a on both the left and right sides of the female differential signal terminal 21, etc., which is not limited here.

[0036] Furthermore, please refer to the following: Figure 6 The connector system 10 also has a height direction Z, and the mating direction X, height direction Z, and horizontal direction Y are mutually perpendicular. The female shielding assembly 22 includes a top shield 223, a bottom shield 222, and two side shields 221 connected to the top shield 223 and the bottom shield 222. The top shield 223 and the bottom shield 222 are spaced apart along the height direction Z. The top shield 223, the bottom shield 222, and the two side shields 221 cooperate to form a cavity for accommodating the female differential signal terminal 21.

[0037] like Figure 2 As shown, side shielding members 221 are respectively disposed on both sides of the female differential signal terminal 21 in the horizontal direction Y. Each first female grounding member 23a is disposed on the corresponding side shielding member 221. Each first female grounding member 23a is located on the side of the corresponding side shielding member 221 facing the female differential signal terminal 21.

[0038] Specifically, the two side shields 221 are located on the left and right sides of the female differential signal terminal 21, respectively. The left-side side shield 221 has a left-side first female grounding component 23a, and the right-side side shield 221 has a right-side first female grounding component 23a. The first female grounding component 23a and the corresponding side shield 221 are two independent components, which can be fixedly connected by welding or other methods, and are electrically connected to each other.

[0039] In this manner, the first female grounding component 23a and the corresponding side shield 221 are two independent components. The side shield 221 does not require a cutout area for forming the first female grounding component 23a, thus ensuring the shielding integrity of the side shield 221 and preventing electromagnetic signal leakage through the cutout area. Simultaneously, by directly placing the first female grounding component 23a on the side shield 221, the electrical connection path between the female grounding component 23a and the female shield assembly 22 is shortened. The return current can flow more directly through the side shield 221 and the first female grounding component 23a to the male shield assembly 32, which helps reduce the impedance of the grounding loop. The side shield 221 itself also participates in shielding the differential signal terminals, forming a horizontal Y-shaped shielding structure together with the first female grounding component 23a.

[0040] In one embodiment, the female grounding component 23 includes a second female grounding component 23b, which is disposed on at least one side of the female differential signal terminal 21 in the height direction Z. The second female grounding component 23b can be disposed above the female differential signal terminal 21, below the female differential signal terminal 21, or both above and below the female differential signal terminal 21. When the female connector 20 and the male connector 30 are mated, the second female grounding component 23b is electrically connected to the male shielding component 32. The second female grounding component 23b provides a grounding path at the bottom of the female differential signal terminal 21, forming a grounding boundary at the bottom of the female differential signal terminal 21, making the shielding structure around the female differential signal terminal 21 more complete and reducing the risk of signal leakage to adjacent signal channels via the bottom.

[0041] Specifically, such as Figure 6 As shown, the second female grounding component 23b is disposed on the side of the bottom shield 222 facing the female differential signal terminal 21. The bottom shield 222 is located below the female differential signal terminal 21, and the second female grounding component 23b is located at the bottom of the female differential signal terminal 21.

[0042] Furthermore, please refer to the following: Figure 7 The number of mother-end differential signal terminals 21 is multiple. These multiple sets of mother-end differential signal terminals 21 are distributed at intervals along the horizontal direction Y. Correspondingly, the number of second mother-end grounding elements 23b is also multiple, and these second mother-end grounding elements 23b are distributed at intervals along the horizontal direction Y. Each set of mother-end differential signal terminals 21 corresponds to a different second mother-end grounding element 23b; that is, a corresponding second mother-end grounding element 23b is provided below one set of mother-end differential signal terminals 21, and another corresponding second mother-end grounding element 23b is provided below an adjacent set of mother-end differential signal terminals 21, and so on.

[0043] Each second female grounding component 23b and the bottom shield 222 are independent components. The second female grounding component 23b and the bottom shield 222 can be fixedly connected by welding or other methods, and are electrically connected. In other words, this embodiment provides multiple second female grounding components 23b on a single bottom shield 222. There is no need to create a cutout area on the bottom shield 222 for forming the second female grounding components 23b, thus maintaining the shielding integrity of the bottom shield 222 and preventing electromagnetic signal leakage between adjacent channels via the cutout area. Simultaneously, each set of female differential signal terminals 21 corresponds to its respective second female grounding component 23b, and adjacent channels are isolated by their respective grounding structures, which helps reduce crosstalk between adjacent signal channels.

[0044] Please continue reading. Figure 6 In one embodiment, the male connector 30 further includes a male grounding member 33 disposed on at least one side of the male differential signal terminal 31 in the height direction Z. The male grounding member 33 is used to electrically connect with the female shielding assembly 22 when the female connector 20 and the male connector 30 are mated together. Specifically, when the female connector 20 and the male connector 30 are mated together, the male grounding member 33 makes electrical contact with the top shielding member 223 of the female shielding assembly 22, thereby providing a grounding path at the top of the female differential signal terminal 21.

[0045] In this embodiment, the first female grounding component 23a, the second female grounding component 23b, and the male grounding component 33 are arranged around the female differential signal terminal 21 from four directions: horizontal sides, bottom, and top, respectively. A complete grounding shield structure is formed around the female differential signal terminal 21, so that the female differential signal terminal 21 has a corresponding grounding path on any side in the four directions. The electromagnetic field is confined to the area enclosed by each grounding component, and the return current can return along the nearest grounding path. Signal leakage and crosstalk between adjacent channels are further suppressed.

[0046] Furthermore, please refer to the following: Figure 8The male grounding component 33 includes a grounding protrusion 331, which is used for electrical connection with the female shielding assembly 22 when the female connector 20 and the male connector 30 are mated. The male grounding component 33 is located on the side of the male shielding assembly 32 facing the female connector 20. The male grounding component 33 and the male shielding assembly 32 are electrically connected and can be fixedly connected by welding, riveting, or integral molding. When the female connector 20 and the male connector 30 are mated, the grounding protrusion 331 contacts the female shielding assembly 22, thereby achieving electrical conduction between the male shielding assembly 32 and the female shielding assembly 22. The grounding protrusion 331 can be single or multiple. When there are multiple grounding protrusions 331, they can be distributed at intervals along the horizontal direction Y, respectively contacting different positions of the female shielding assembly 22 to form multiple parallel grounding contacts.

[0047] In this embodiment, when the female connector 20 and the male connector 30 are mated together, the grounding protrusion 331 of the male grounding component 33 forms an abutting contact with the female shielding component 22, achieving a direct grounding connection between the male shielding component 32 and the female shielding component 22. When there are multiple grounding protrusions 331, these protrusions form multiple points of contact with the female shielding component 22, and these multiple contact points are at the same level. This helps to reduce the grounding impedance between the male shielding component 32 and the female shielding component 22, ensuring potential consistency between them.

[0048] Specifically, the male-end shielding assembly 32 includes a shielding body 321, a base 322, and a plurality of elastic bodies 323 connected to the base 322. The shielding body 321 and the base 322 cooperate to form a cavity for accommodating the male-end differential signal terminal 31, which is located within the cavity.

[0049] The shielding body 321 covers the bottom of the male differential signal terminal 31 and both sides of the male differential signal terminal 31 in the horizontal direction Y, and the substrate 322 is located above the male differential signal terminal 31, thereby forming a shielding structure on the outer periphery of the male differential signal terminal 31.

[0050] Multiple elastic bodies 323 are connected to the base 322, and are spaced apart along the horizontal direction Y. Each elastic body 323 is provided with a grounding protrusion 331. One end of the elastic body 323 is connected to the base 322, and the other end is a free end, on which the grounding protrusion 331 is provided. When the female connector 20 and the male connector 30 are mated, the free end of the elastic body 323 undergoes elastic deformation, and the grounding protrusion 331 is pressed against the female shielding assembly 22 by the elastic force of the elastic body 323 itself, achieving stable electrical contact. The multiple elastic bodies 323 are spaced apart along the horizontal direction Y, and each elastic body 323 is provided with a grounding protrusion 331. Multiple parallel grounding paths are formed between the female shielding assembly 22 and the male shielding assembly 32 through the multiple elastic bodies 323, reducing the grounding impedance between them. At the same time, the elastic body 323 undergoes elastic deformation during mating, which absorbs part of the positional error during the mating process, reducing the requirements for the processing accuracy of each component.

[0051] Please continue reading. Figure 3 In one embodiment, one of the at least two grounding terminals 231 of the female grounding component 23 is a resilient contact 232, and the other grounding terminal 231 is a resilient sliding contact 233. The resilient contact 232 is used to make electrical contact with the male shielding component 32 when the female connector 20 and the male connector 30 are mated together. The resilient sliding contact 233 is used to make contact with the male shielding component 32 when the female connector 20 and the male connector 30 are mated together, and slides in the same direction as the mating action. It should be noted that both the first female grounding component 23a and the second female grounding component 23b have a resilient contact 232 and a resilient sliding contact 233. Figure 3 The example of the first female grounding component 23a is used for illustrative purposes only.

[0052] Specifically, one end of the elastic contact 232 is fixed to the female grounding member 23, and the other end is a free end. The free end extends towards the male connector 30. When the female connector 20 and the male connector 30 are mated, the free end of the elastic contact 232 abuts against the male shielding component 32 and undergoes elastic deformation, with the abutment position remaining essentially unchanged. One end of the elastic sliding contact 233 is fixed to the female grounding member 23, and the other end is a free end. The free end of the elastic sliding contact 233 is the end furthest from the male connector 30. When the female connector 20 and the male connector 30 are mated, the free end of the elastic sliding contact 233 abuts against the male shielding component 32 and undergoes elastic deformation. As the mating depth increases, the free end of the elastic sliding contact 233 slides along the surface of the male shielding component 32 in the mating direction X. This unidirectional sliding means that the sliding direction of the free end of the elastic sliding contact 233 is consistent with the mating direction X.

[0053] In this way, the free end of the elastic sliding contact 233 can slide in the same direction as the mating action. The structural portion of the female grounding component 23 located behind the elastic sliding contact 233 is compensated by the sliding of the free end during the mating process. This means that the effective electrical length of the grounding terminal 231 in the mating direction X no longer depends on the physical length of the female grounding component 23, but is determined by the contact position after sliding. The structural portion of the grounding terminal 231 located behind the contact position no longer participates in the grounding of the signal transmission path, and its electrical effect as a short stake is eliminated, avoiding resonance of this part of the structure at a specific frequency. The elastic contact 232 maintains a relatively fixed contact position during mating, providing a stable grounding reference point for the differential signal terminal. The elastic sliding contact 233 slides in the same direction during mating, eliminating the residual short stake behind the female grounding component 23. Together, they provide a stable grounding connection while reducing the risk of resonance introduced by the short stake.

[0054] Please continue reading. Figure 2 and Figure 3 This application also provides a female connector 20. The female connector 20 is capable of mating with a male connector 30 along the mating direction X. The female connector 20 includes a female differential signal terminal 21, a female shielding component 22, and a female grounding component 23. The female shielding component 22 is electrically connected to the female grounding component 23, and the female grounding component 23 has at least two grounding terminals 231 arranged at intervals along the mating direction X. When the female connector 20 and the male connector 30 are mated, the female differential signal terminal 21 and the differential signal terminal of the male connector 30 are electrically connected, and the at least two grounding terminals 231 are electrically connected to the shielding component of the male connector 30.
