[0061] The present application will be described in detail below with reference to the various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present application, and any structural, methodological, or functional modifications made by a person skilled in the art based on these embodiments are included within the scope of protection of the present application.

[0062] The first direction, second direction and docking direction defined in this application are all based on Figure 1, where the X direction shown in Figure 1 is the first direction, the Y direction perpendicular to the X direction is the second direction, and the Z direction perpendicular to the X direction and the Y direction is the docking direction.

[0063] In order to ensure isolation between adjacent terminal groups of the connector and unified grounding of each grounding terminal in the terminal group, a shielding plate is currently arranged on one side of the terminal group. The shielding plate contacts each grounding terminal to achieve unified grounding.

[0064] The shield plate of a traditional connector uses a snap-on method to connect to the ground terminal. The shield plate is equipped with a snap that faces the ground terminal, and a corresponding snap notch is provided on the ground terminal. The snap and notch form an interference fit to achieve contact and connection. This fixing method cannot ensure the contact stability and secure fixation between the ground component and each ground terminal, which has a certain impact on transmission speed. Furthermore, each ground terminal requires a snap notch, and the ground component also needs to have a corresponding snap structure. This leads to high production costs, cumbersome steps, and low yield rates.

[0065] In order to solve the above problems, the applicant provides a new type of connector assembly, the terminal group of which can ensure stable contact between each grounding terminal and the grounding assembly, and the grounding assembly is firmly fixed, thereby ensuring the stability of the transmission speed, which can reach 56G high-speed transmission.

[0066] Specifically, please refer to FIG1 , which is a schematic structural diagram of an embodiment of a connector assembly of the present application.

[0067] As shown in FIG. 1 , the connector assembly includes a connector 1 a and a mating connector 1 b mated with the connector 1 a .

[0068] The connector 1a includes a plurality of terminal groups 10a arranged at even intervals along the second direction Y and an insulating seat 20a for fixing the terminal groups 10a. Each terminal group 10a includes a plurality of terminals 100a arranged at even intervals along the first direction X.

[0069] The docking connector 1b includes a plurality of docking terminal groups 10b arranged at even intervals along the second direction Y and a docking insulating seat 20b for fixing the docking terminal groups 10b. Each docking terminal group 10b includes a plurality of docking terminals 100b arranged at even intervals along the first direction X, and each docking terminal 100b corresponds to each terminal 100a.

[0070] It can be understood that when the connector 1a and the mating connector 1b are mated with each other, the corresponding mating terminals 100b and terminals 100a come into contact to achieve electrical connection.

[0071] The structure of the terminal assembly 10a is described in detail below to illustrate the fixing method of the grounding assembly in this application. Please refer to Figures 2 and 3. Figure 2 is a schematic diagram of the structure of an embodiment of the terminal assembly in this application, and Figure 3 is a schematic diagram of the structure of a terminal in an embodiment of the terminal assembly in this application.

[0072] As shown in FIG. 2 and FIG. 3 , the terminal group 10 a includes a plurality of terminals 100 a arranged at intervals along a first direction x.

[0073] The plurality of terminals 100a include a plurality of ground terminals 1000 and a plurality of signal terminals 2000. The ground terminals 1000 include a ground contact section 101a, a ground fixing section 102a, and a ground mounting section 103a connected in sequence. The signal terminals 2000 include a signal contact section 101A, a signal fixing section 102A, and a signal mounting section 103A connected in sequence.

[0074] In one embodiment, the ground terminal 1000 and the signal terminal 2000 may be planar structures located in the same plane and may extend in the same direction. Specifically, as shown in the figure, the ground contact segment 101a of the ground terminal 1000 may extend along the mating direction Z, and the width direction of the ground contact segment 101a may be parallel to the first direction x. The ground mounting segment 103a may extend along the first direction x, and the width direction of the ground mounting segment 103a may be parallel to the mating direction Z.

[0075] Correspondingly, the signal contact section 101A of the signal terminal 2000 can extend along the mating direction Z, the width direction of the signal contact section 101A can be parallel to the first direction x, the signal installation section 103A can be extended along the first direction x, and the width direction of the signal installation section 103A can be parallel to the mating direction Z.

[0076] In other embodiments, the ground terminal 1000 may also be a three-dimensional structure that is not located in a single plane, and the signal terminal 2000 may also be a three-dimensional structure that is not located in a single plane. For example, the ground contact segment 101a of the ground terminal 1000 may extend along the mating direction Z, and the width direction of the ground contact segment 101a may be parallel to the first direction x. The ground mounting segment 103a may extend along the second direction y, and the width direction of the ground mounting segment 103a may be parallel to the first direction x or the mating direction Z, thereby forming a curved L-shaped terminal.

[0077] Correspondingly, the signal contact section 101A of the signal terminal 2000 can extend along the mating direction Z, and the width direction of the signal contact section 101A can be parallel to the first direction x. The signal installation section 103A can be extended along the second direction y, and the width direction of the signal installation section 103A can be parallel to the first direction x or the mating direction Z, thereby forming a curved L-shaped terminal.

[0078] Alternatively, in other embodiments, the grounding mounting section 103a of the grounding terminal 1000 and the signal mounting section 103A of the signal terminal 2000 may not be extended along the second direction y. For example, the extension direction of the grounding mounting section 103a of the grounding terminal 1000 may be cross-set with the extension direction of the grounding contact section 101a, and the extension direction of the signal mounting section 103A of the signal terminal 2000 may be cross-set with the extension direction of the signal contact section 101A. Both of these can achieve the effects of this embodiment and are not limited here.

[0079] In one embodiment, a pair of signal terminals 2000 is provided between adjacent ground terminals 1000, forming a signal pair. In other embodiments, the number of terminals in a signal pair can be adjusted based on actual conditions, and ground terminals 1000 can be provided between adjacent signal pairs, thereby achieving the effects of this embodiment.

[0080] The terminal assembly 10a further includes an insulator 200a in which the grounding fixing section 102a of the ground terminal 1000 and the signal fixing section 102A of the signal terminal 2000 are fixed. The insulator 200a includes a first surface 201 and a second surface 202 (not shown) disposed opposite to each other.

[0081] In order to achieve shielding between adjacent terminal groups 10a and ensure signal interference shielding effect, the first surface 201 is further arranged with a conductive shielding plate 300a, which can be electrically connected to each grounding terminal 1000 to achieve unified grounding.

[0082] The connection method between the conductive shielding plate 300 a and the grounding terminal 1000 will be described in detail below. Please refer to FIG. 4 , which is a schematic cross-sectional view of the structure along the AA plane in FIG. 2 .

[0083] 4 , the grounding terminal 1000 has a grounding region 1001 on the grounding fixing section 102a, and the insulator 200a has hollow regions 203 exposing the grounding region 1001. Accordingly, the conductive shielding plate 300a has a first boss region 301 embedded in each hollow region 203 on the side facing the first surface 201.

[0084] The first boss area 301 and the corresponding grounding area 1001 are tightly fitted and fixed, thereby achieving a stable connection between the conductive shielding plate 300 a and each grounding terminal 1000 .

[0085] Specifically, the conductive shielding plate 300a can be fixed to the ground terminal 1000 by laser welding. To facilitate the laser welding operation, the conductive shielding plate 300a is further provided with a first recessed area 302 corresponding to the first boss area 301 on the side facing away from the first surface 201, so that the position of the first boss area 301 can be calibrated during processing.

[0086] It is understandable that when fixing the conductive shielding plate 300a, the first boss area 301 can be embedded in the corresponding hollow area 203 first, and then laser welding is performed on the bottom surface of the first recessed area 302 to achieve fixation of the first boss area 301 and the grounding area 1001.

[0087] To further achieve common grounding of the grounding terminals 1000 in the terminal group 10a, in another embodiment, the terminal group 10a further includes a grounding bar 500. Referring to Figures 5 and 6, Figure 5 is a schematic structural diagram of another embodiment of the terminal group of the present application, and Figure 6 is a schematic cross-sectional structural diagram along plane BB in Figure 5.

[0088] As shown in the figure, the grounding strip 500 may be extended along the first direction x and arranged on the second surface 202 , and may cover each hollow area 203 .

[0089] A second boss area 501 embedded in each hollow area 203 can be provided on the side of the grounding strip 500 facing the second surface 202 . The second boss area 501 can be tightly fitted and fixed to the corresponding grounding area 1001 , thereby achieving a stable connection between the grounding strip 500 and each grounding terminal 1000 .

[0090] Specifically, the second boss area 501 can be fixed to the grounding area 1001 by laser welding. To facilitate the laser welding operation, a second recessed area 502 corresponding to the second boss area 501 can be provided on the side of the grounding strip 500 facing away from the second surface 202 to mark the position of the second boss area 501.

[0091] It is understandable that when installing the grounding strip 500 , the second boss area 501 can be first embedded in the corresponding hollow area 203 , and then laser welding can be performed on the bottom surface of the second recessed area 502 to achieve fixation of the second boss area 501 and the grounding area 1001 .

[0092] The two sides of the grounding terminal 1000 are laser welded to the conductive shielding plate 300a and the grounding strip 500 to form a sandwich structure, which can effectively ensure the contact stability of the conductive shielding plate 300a and the grounding strip 500 with each grounding terminal 1000, ensure the unified grounding effect of the terminal group, and help to improve the transmission speed.

[0093] In the above embodiment, to improve the fixing stability of the conductive shielding plate 300a and facilitate the placement of the grounding strip 500, the grounding region 1001 of the grounding terminal 1000 is positioned near one end of the grounding fixing section 102a of the grounding terminal 1000, thereby securing the end of the conductive shielding plate 300a. Accordingly, the grounding strip 500 is positioned near one end of the grounding contact section 101a on the second surface 202. In other embodiments, the grounding region 1001 may also be positioned elsewhere on the grounding terminal 1000, and the design can be adjusted based on the operating conditions, while still achieving the effects of this embodiment.

[0094] The above embodiment only illustrates one method of welding fixation between the conductive shielding plate 300a, the grounding terminal 1000, and the grounding strip 500. In other embodiments, welding fixation may not be employed. For example, the conductive shielding plate 300a, the grounding terminal 1000, and the grounding strip 500 may be fixed by conductive adhesive, which can also achieve the purpose of stable connection. Alternatively, other welding fixation methods may be employed, such as by adding welding parts to achieve stable fixation of the three. The following detailed description is provided in Figures 7 and 8. Figure 7 is a schematic structural diagram of another embodiment of the terminal assembly of the present application, and Figure 8 is a schematic cross-sectional structural diagram of the CC plane in Figure 7.

[0095] As shown in Figures 7 and 8, in this embodiment, a first opening 1002 is provided on the grounding area 1001 of each grounding terminal 1000. The grounding terminal 1000 and the first boss area 301 are welded and fixed to the grounding terminal 1000 and the conductive shielding plate 300a by corresponding welding at the first opening 1002, thereby ensuring stable contact and firm fixation.

[0096] Specifically, in this embodiment, the ground terminal 1000 and the conductive shielding plate 300a can be fixed by soldering at the first opening 1002, and the solder 400 is filled in the hole during the welding process to achieve fixation of the ground terminal 1000 and the conductive shielding plate 300a.

[0097] In other embodiments, other welding methods may be used at the first opening 1002 to fix the ground terminal 1000 and the first boss area 301. For example, a welding part may be pre-set in the first opening 1002. The welding part may be a conductive metal material, and the fixation is achieved by welding the welding part to the ground area 1001 and the first boss area 301 respectively.

[0098] Based on the welding structure of the above embodiment, when the grounding bar 500 is provided on the second surface 202, the grounding bar 500 can also be fixed simultaneously. Please refer to Figure 9, which is a cross-sectional structural diagram of another embodiment of the terminal assembly of the present application.

[0099] As shown in Figure 9, a second opening 503 corresponding to the first opening 1002 is provided on the second boss area 501 of the grounding strip 500. In the above embodiment, the solder 400 filled in the first opening 1002 during the welding process can pass through the first opening 1002 and the second opening 503, thereby realizing the welding fixation between the conductive shielding plate 300a, the grounding terminal 1000 and the grounding strip 500.

[0100] In other embodiments, a welding part that passes through the first opening 1002 and the second opening 503 can also be preset in the first opening 1002. The welding part can be simultaneously welded to the first boss area 301, the grounding terminal 1000, and the grounding strip 500, thereby achieving welding fixation between the conductive shielding plate 300a, the grounding terminal 1000 and the grounding strip 500.

[0101] In the above embodiments, only one grounding area 1001 is provided on each grounding terminal 1000. In other embodiments, the number of grounding areas 1001 on the grounding terminal 1000 can also be selected based on actual working conditions. For example, grounding areas 1001 can be provided at both ends and in the middle of the grounding fixing section 102a of each grounding terminal 1000, so as to achieve stable fixation of the conductive shielding plate 300a and the grounding strip 500 and stable contact with each grounding terminal 1000.

[0102] Please refer to Figures 5, 10, and 11. Figure 10 is a partially enlarged schematic diagram of area A in Figure 5, and Figure 11 is a schematic structural diagram of one embodiment of the conductive shielding plate of the present application. To achieve multi-point contact between the conductive shielding plate 300a and the grounding terminal 1000, and to facilitate positioning of the conductive shielding plate 300a during installation, the insulator 200a is further provided with a plurality of openings 204. The orthographic projection of each opening 204 on the first surface 201 is covered by the orthographic projection of a grounding terminal 1000 on the first surface 201.

[0103] Specifically, the multiple opening areas 204 are divided into several groups, each group corresponds to a grounding terminal 1000, and the multiple opening areas 204 in each group can be evenly arranged along the extension direction of the corresponding grounding terminal 1000, and the surface of the conductive shielding plate 300a can be provided with a ridge 303 embedded in the opening area 204.

[0104] The end surface of the ridge 303 can be arranged parallel to the surface of the ground terminal 1000 in the second direction Y, but not in contact with each other. Furthermore, the ground terminal 1000 can be provided with a third opening 1003 corresponding to the position of the opening area 204. A spring arm 1004 can be positioned within the third opening 1003. One end of the spring arm 1004 is connected to the inner wall of the third opening 1003, and the other end presses against the ridge 303 along the direction from the second surface 202 to the first surface 201, thereby further improving the connection stability between the ground terminal 1000 and the conductive shielding plate 300a. This arrangement can improve signal transmission performance while maintaining connection stability.

[0105] It is understandable that in other embodiments, based on actual working conditions, the end surface of the ridge 303 can be directly connected to the ground terminal 1000 to ensure the connection stability between the ground terminal 1000 and the conductive shielding plate 300a.

[0106] Please refer to Figures 5 and 12. Figure 12 is a schematic cross-sectional view of the structure taken along plane DD in Figure 5. As shown in the figure, to further improve signal transmission speed, the grounding strip 500 is provided with a plurality of grounding protrusions 504 on the side near the grounding contact segment 101a. The grounding protrusions 504 are located at the orthographic projections of the grounding terminals 1000 on the grounding strip 500. The grounding protrusions 504 extend from the side of the grounding strip 500 in a direction toward the grounding contact segment 101a.

[0107] In one embodiment, the extension length of the grounding protrusion 504 in the mating direction Z may be 0.2-1.2 mm, and the spacing between adjacent grounding protrusions 504 may be 1.5-3.5 mm, so that the high transmission rate reaches 56G.

[0108] 2 and 12 , in order to improve signal transmission speed, the conductive shielding plate 300a may also be provided with a plurality of shielding protrusions 304 on a side close to the ground contact segment 101a, each shielding protrusion 304 being located at the positive projection of the ground terminal 1000 on the conductive shielding plate 300a.

[0109] In one embodiment, the extension length of the shielding protrusion 304 in the mating direction Z may be 0.2-2.2 mm, and the spacing between adjacent shielding protrusions 304 may be 0.5-2.5 mm, so that the high transmission rate reaches 56G.

[0110] Further, referring to Figure 12, the grounding contact segment 101a is a cantilever structure extending out of the insulator 200a. When in the docked state, it is deformed by the pressure of the docking terminal. In order to support the grounding contact segment 101a and improve its strength, the insulator 200a is further provided with a supporting protrusion 205 that wraps the inner end of the grounding contact segment 101a on the side facing the grounding contact segment 101a.

[0111] It is understood that when the ground contact segment 101a is under pressure in the mated state, the supporting protrusion 205 can support the ground contact segment 101a from its backside, thereby increasing its strength. Accordingly, in this embodiment, the side of the insulator 200a may also be provided with a protrusion (not shown) that wraps around the end of the signal contact segment 101A to support the signal contact segment 101A in the mated state.

[0112] Considering that the ground terminal 1000 is wider than the signal terminal 2000, the inner end of the ground contact segment 101a is subjected to greater force than the signal contact segment 101A in the docked state. In order to further improve the support for the inner end of the ground contact segment 101a, in this embodiment, the grounding protrusion 504 also extends to the surface of the supporting protrusion 205 to support the end of the ground contact segment 101a.

[0113] In other embodiments, the shielding protrusion 304 may also extend to the surface of the supporting protrusion 205 to support the end of the grounding contact segment 101a; or, only the shielding protrusion 304 may extend to the surface of the supporting protrusion 205 to support the end of the grounding contact segment 101a. The design can be adjusted based on the force direction of the grounding contact segment 101a during actual docking.

[0114] In particular, in some embodiments, the supporting protrusion 205 of the insulator 200 a may be located between the shielding protrusion 304 and the grounding protrusion 504 , thereby achieving simultaneous support of the cantilever structure of the ground contact segment 101 a in two directions.

[0115] In some embodiments, when multiple terminal groups 10a are arranged along the second direction Y to form a connector 1a, when docking, the pressure directions of the grounding contact segments 101a of adjacent terminal groups 10a can be opposite, the grounding protrusion 504 of the terminal group 10a on one side can extend to one side surface of the support protrusion 205, and the shielding protrusion 304 of the terminal group 10a on the other side can extend to the other side surface of the support protrusion 205, thereby realizing docking support of the grounding contact segments 101a of the two adjacent terminal groups 10a.

[0116] In order to further improve the fixing strength of the structure, please refer to FIG. 2 and FIG. 13 . FIG. 13 is a schematic cross-sectional view of the structure along the EE plane in FIG. 2 .

[0117] As shown in the figure, the insulator 200a is also provided with a boss 206 extending toward one side of the conductive shielding plate 300a. The boss 206 passes through the conductive shielding plate 300a and is arranged to cooperate with the conductive shielding plate 300a, thereby reinforcing the connection stability between the insulator 200a and the conductive shielding plate 300a in the second direction Y.

[0118] In each of the above embodiments, the first boss area 301 and the second boss area 501 are both complete enclosed structures and do not extend to the ends. In other embodiments, to optimize the layout, the first boss area 301 and the second boss area 501 may also be non-enclosed structures. Specifically, please refer to Figures 14 to 16. Figure 14 is a schematic structural diagram of another embodiment of the terminal assembly of the present application, Figure 15 is a schematic structural diagram of the first surface of another embodiment of the insulator of the present application, and Figure 16 is a schematic structural diagram of another embodiment of the conductive shielding plate of the present application.

[0119] As shown in Figures 14 to 16, to further optimize the layout of the first protrusion areas 301, improve space utilization, and enhance signal quality, in this embodiment, two first protrusion areas 301 at the end in the first direction x are non-enclosed structures, extending to the end of the conductive shielding plate 300 near the ground contact segment 101a. These two first protrusion areas 301 are designated as first notched protrusion areas 301a; the remaining first protrusion areas 301 are enclosed structures. This design saves space at the end in the first direction x of the terminal assembly 10a and the conductive shielding plate 300a, facilitating production while also enhancing signal quality.

[0120] Of course, in other implementations, the first notch and boss area 301a may not be arranged at the end of the first direction x, and its arrangement position and number may be adjusted based on actual needs to reduce space occupation in a specific area and improve the signal.

[0121] In this embodiment, the two first notched and protruding land areas 301a are square structures with one end open. In other embodiments, the structure can be adjusted based on actual needs. For example, the first notched and protruding land areas 301a can also be a semi-waisted shape, a notched circular shape, or a notched elliptical shape, etc., all of which can achieve the effects of this embodiment. In this embodiment, the first protruding land areas 301 other than the first notched and protruding land areas 301a are closed circular structures. In other embodiments, they can also be adjusted to square, waist-shaped, elliptical, etc., as long as they can achieve close contact between the first protruding land areas 301 and the grounding area 1001, and all of which can achieve the effects of this embodiment.

[0122] In this embodiment, to optimize the structure of insulator 200a and maximize size savings, insulator 200a includes a protrusion 208 positioned near one end of ground contact segment 101a. Protrusion 208 secures a portion of ground securing segment 102a of ground terminal 1000. To accommodate solder joints within the limited space of protrusion 208, a first notched protrusion area 301a is positioned on the conductive shielding plate 300 at a location corresponding to protrusion 208.

[0123] In order to optimize the layout, the first boss areas 301 in this embodiment can be arranged in a one-to-one correspondence with the shielding protrusions 304, at least a portion of each first boss area 301 is arranged at the corresponding shielding protrusion 304, and the first notch boss area 301a extends to the end of the corresponding shielding protrusion 304 close to the ground contact section 101a.

[0124] Further, please refer to Figures 17 to 19. Figure 17 is a structural schematic diagram of another perspective of another embodiment of the terminal group of the present application, Figure 18 is a structural schematic diagram of the second surface of another embodiment of the insulator of the present application, and Figure 19 is a structural schematic diagram of another embodiment of the grounding strip of the present application.

[0125] As shown in Figures 17 to 19, to optimize the layout of the second protrusion area 501, improve space utilization, and enhance signal quality, in this embodiment, one second protrusion area 501 at the end in the first direction x is a non-enclosed structure, extending to the end of the grounding strip 500 near the grounding contact segment 101a. This second protrusion area 501 is designated as the second notched protrusion area 501a; the remaining second protrusion areas 501 are enclosed structures. This design saves space between the terminal block and the end in the first direction of the grounding strip, facilitates production, and improves signal quality.

[0126] Of course, in other implementations, the second notch boss area 501a may not be arranged at the end of the first direction x, and its arrangement position and quantity may be adjusted based on actual needs to reduce space occupation in a specific area and improve the signal.

[0127] Similar to the first boss area 301 and the first notched boss area 301a, the shapes of the second boss area 501 and the second notched boss area 501a are not limited. The second boss area 501 can be circular, square, waist-shaped, elliptical, etc., and the second notched boss area 501 can be square, half-waisted, notched circular, or notched elliptical, etc., all of which can achieve the effects of this embodiment.

[0128] In order to arrange welding points in the protruding portion 208 with limited space, in this embodiment, the second notch boss area 501 a is arranged at a position corresponding to the grounding strip 500 and the protruding portion 208 .

[0129] In order to optimize the layout, the second boss areas 501 in this embodiment can be arranged in a one-to-one correspondence with the grounding protrusions 504, at least a portion of each second boss area 501 is arranged at the corresponding grounding protrusion 504, and the second notch boss area 501a extends to the end of the corresponding grounding protrusion 504 close to the grounding contact section 101a.

[0130] In order to further improve the positioning accuracy and fixing strength of the grounding strip 500 and facilitate the assembly of the grounding strip 500, please refer to Figure 20, which is a schematic diagram of the assembly structure of the insulator and the grounding strip in another embodiment of the terminal assembly of the present application.

[0131] As shown in FIG. 20 , a fixing column 207 is provided on the second surface 202 of the insulator 200 a , and a fixing hole 505 matching the fixing column 207 is arranged on the grounding bar 500 .

[0132] The fixing post 207 is disposed through the fixing hole 505 of the grounding bar 500 , thereby reinforcing the connection stability between the insulator 200 a and the grounding bar 500 .

[0133] In this embodiment, the fixing holes 505 are arranged at both ends of the grounding strip 500. In other embodiments, the positions and numbers of the fixing holes 505 can also be adjusted based on actual needs, and the effects of this embodiment can be achieved.

[0134] In one embodiment, to further improve signal crosstalk, the width of the signal contact section 101A of the signal terminal 2000 is not constant. Referring to FIG. 21 , FIG. 21 is a schematic structural diagram of an embodiment of the signal terminal of the present application. As shown, the signal contact section 101A of the signal terminal 2000 includes an extension portion 1021A and a contact portion 1022A, which are sequentially arranged in a direction away from the signal fixed section 102A. The width CD of the contact portion 1022A is greater than the width AB of the extension portion 1021A to improve signal crosstalk.

[0135] The above embodiment only takes connector 1a as an example to elaborate on a terminal group structure that can effectively improve the grounding effect and signal transmission speed, wherein the terminal group structure of the docking connector 1b can be the same as or different from the terminal group structure of connector 1a, and both can achieve the effects of this embodiment.
