[0044] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of the embodiments of "connector with a mating assembly structure and its terminal assembly and relay junction box" disclosed in this application is provided in conjunction with specific embodiments and with reference to the accompanying drawings. Those skilled in the art can understand the advantages and effects of this application from the content disclosed in this specification. This application can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of this application. Furthermore, it should be stated in advance that the accompanying drawings of this application are only simple schematic illustrations and are not depictions based on actual dimensions. Although this document provides examples of parameters containing specific values, it should be understood that the parameters do not need to be exactly equal to the corresponding values, but can approximate the corresponding values ​​within acceptable error tolerances or design constraints. In addition, unless the context clearly indicates or defines it, the meanings of "a," "the," and "the" in this application include the plural.

[0045] It should be understood that although terms such as "first," "second," etc., may be used herein to describe various components or signals, each described component or signal should not be limited by the foregoing terms, which are primarily used to distinguish one component from another or one signal from another. Furthermore, directional terms mentioned in subsequent embodiments, such as "up," "down," "front," "back," "left," and "right," are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the scope of protection of this application. Additionally, the term "or" as used herein may, depending on the specific circumstances, include any combination of one or more of the associated listed items.

[0046] Furthermore, the terms "substantially" or "approximately" as used herein can refer to the average of a numerical or complex numerical value within a range of deviations from a particular value that can be recognized or determined by those skilled in the art, including taking into account certain specific errors that may occur when measuring the particular value due to limitations of the measurement system or equipment. For example, the numerical value referred to "substantially" can include ±5%, ±3%, ±1%, ±0.5%, ±0.1%, or one or more standard deviations of the particular value.

[0047] It should be specifically noted that some components in this application may have the same or similar structures, differing only in their placement. For example, two sets of female terminal blocks may be located on the front and rear sides of the relay connector, but they may not have substantial differences in structure or function. Therefore, in the claims, for clarity and ease of description, components with similar or identical structures are referred to as "first" and "second," such as first metal terminal, second metal terminal, first housing fitting unit, second housing fitting unit, etc. Furthermore, if the component is applicable to either a male connector or a female connector, the claims may not separately use the terms "male" or "female." Therefore, unless otherwise specified, the term "two sets of female terminal blocks" in this specification corresponds to and includes the "first terminal block," "second terminal block," etc., mentioned in the claims. Similarly, it can be inferred that other paired components can also be distinguished by "first" and "second." The reason why "first terminal group" and "second terminal group" are not explicitly used in the text and drawings in this specification is merely to make the description more concise and does not affect the technical content or patent protection scope of this application. In the following description, if a uniform component number is used (such as: terminal block 23, metal shield 24, etc.), it can also be matched with the above-mentioned "first", "second", etc. components as needed.

[0048] This application discloses a connector with a mating assembly structure, its terminal assembly, and a relay connector. It is primarily designed for use in connector assembly C and can be applied to signal or power transmission in electronic devices. The basic architecture of connector assembly C is described below; please refer to [link to relevant documentation]. Figures 1A to 1D As shown, the connector group C includes a female connector C1 and a male connector C2 that can be plugged into each other. The female connector C1 can be connected to one transmission medium, and the male connector C2 can be connected to another transmission medium. When the female connector C1 and the male connector C2 are plugged into each other, power and / or signal transmission between the two transmission mediums can be realized. Furthermore, due to the diversity of product requirements, the two transmission mediums can be the same or different in type; for example, they can be circuit boards or transmission lines.

[0049] Furthermore, with the increasing prevalence of high-speed signal transmission and high-power applications, electromagnetic performance issues such as electromagnetic interference (EMI), electromagnetic compatibility (EMC), and crosstalk are becoming increasingly important. Therefore, this application specifically focuses on a design approach that optimizes electromagnetic performance to ensure reliable connection and signal integrity of the connector assembly C. Figures 1A to 1D As shown below, the structural components and their technical features in the female connector C1 or male connector C2 will be described in detail to illustrate the relevant structural features for achieving the electromagnetic performance optimization of this application. Furthermore, the structural features of some components may be applied to the female connector C1 and / or male connector C2 according to actual needs, and are not limited to the forms of subsequent embodiments; this is stated beforehand.

[0050] To facilitate the explanation of component features and relative positional relationships, the spatial form of the components will be defined in the following description based on three mutually orthogonal axes: the horizontal axis (X-axis), the vertical axis (Y-axis), and the center axis (Z-axis). Specifically, the horizontal axis (X-axis) refers to the left-right extension direction. Figure 1A The lower left corner is used as the left side of the component. Figure 1A The upper right of the axis is defined as the right side of the component; the vertical axis (Y-axis) refers to the front-to-back extension direction, where... Figure 1A The upper left corner serves as the front direction of the component. Figure 1A The lower right side is considered the rear direction of the component; the vertical axis (Z-axis) refers to the vertical extension direction. Figure 1A The area above is considered the top (top) side of the component. Figure 1A The area below is used as the bottom (bottom) side direction of the component.

[0051] In one embodiment, please refer to Figure 2As shown, the female connector C1 includes a female insulating body 1, multiple sets of female terminal groups 2, and a female housing 3. The top side of the female insulating body 1 has a pair of interfaces 11, and a receiving space 10 is provided inside the female insulating body 1. The receiving space 10 is connected to the pair of interfaces 11 and is used to accommodate the female terminal groups 2. Furthermore, the female housing 3 has a mounting space 30, which is used to accommodate the female insulating body 1, thereby improving the structural protection performance of the female insulating body 1 and effectively enhancing its electromagnetic interference (EMI) protection capability, ensuring the electromagnetic compatibility (EMC) of the female connector C1 during high-speed signal transmission.

[0052] Please refer to the above. Figures 1A to 2 As shown, when the female connector C1 is plugged into the male connector C2, the mating interface 11 of the female insulating body 1 can be adapted to the mating portion 5 of the male connector C2, so that the mating portion 5 can extend into the receiving space 10 through the mating interface 11 and form an electrical connection with the female terminal group 2. However, in other embodiments of this application, some structures and components of the female connector C1 can be adjusted according to actual needs. For example, the number of female terminal groups 2 can be one or more; or, the female connector C1 can omit the female housing 3, etc., to improve the design flexibility of the product.

[0053] Additionally, please refer to Figures 3A to 3B As shown, the female terminal group 2 includes multiple female metal terminals. In this embodiment, the female metal terminals can be arranged along the horizontal axis (X-axis), and their types can be distinguished as female signal terminals 21 and female grounding terminals 22, which can be manufactured using different production processes. For details, please refer to... Figure 4A and Figure 4BAs shown, the female signal terminal 21 is manufactured using a forming process, which involves first cutting a metal sheet into a long strip and then bending it into shape. The female signal terminal 21 is divided from top to bottom along the vertical axis (Z-axis) into a signal contact section 211, a signal relay section 212, and a signal fixing section 213. The signal contact section 211 is used to electrically connect to the male signal terminal 61 of the male connector C2. The signal fixing section 213 is used to fix (e.g., solder) it to the circuit board. The signal relay section 212 is located between the signal contact section 211 and the signal fixing section 213. Between 13; the female grounding terminal 22 is formed by blanking, which is to directly cut the metal sheet into shape, and the female grounding terminal 22 is divided into a grounding contact section 221, a grounding relay section 222 and a grounding fixing section 223 from top to bottom along the vertical axis (Z axis). The grounding contact section 221 is used to electrically connect the male grounding terminal 62 of the male connector C2, the grounding fixing section 223 is used to fix (e.g., solder) to the circuit board, and the grounding relay section 222 is located between the grounding contact section 221 and the grounding fixing section 223.

[0054] Please participate Figure 5A and Figure 5B The diagram illustrates the arrangement of some of the female signal terminals 21 and female ground terminals 22. Two female ground terminals 22 can be adjacent to two female signal terminals 21. Viewed from the side, the horizontal projection area (along the horizontal axis, i.e., the X-axis) of the female ground terminal 22 completely covers the female signal terminal 21, but this is not a limitation. In some embodiments, it is sufficient if the horizontal projection area of ​​the grounding fixed section 223 of the female ground terminal 22 completely covers the signal fixed section 213 of the female signal terminal 21. Thus, for the signal transmission path between the female signal terminal 21 and the circuit board, the female ground terminal 22 (or at least the grounding fixed section 223) can form a three-dimensional "enveloping" environment, creating isolation and shielding effects. This can reduce electromagnetic coupling between the female signal terminals 21 located on opposite sides and suppress crosstalk interference. In this embodiment, the end position of the grounding fixed segment 223 of the female grounding terminal 22 differs from the end position of the signal fixed segment 213 of the female signal terminal 21 on the longitudinal axis (Y-axis). In other words, the end position of the grounding fixed segment 223 extends beyond the end position of the signal fixed segment 213 (e.g., Figure 4A (As shown), to enhance the shielding effect of the grounding terminal 22 of the female end, but not limited thereto.

[0055] Furthermore, in order to reduce parasitic capacitance or unnecessary coupling between metal terminals, and to reserve more space for the female signal terminal 21 within the predetermined design space or terminal spacing constraints, please refer to the following embodiment: Figures 5A to 5BAs shown, at least 80% of the area of ​​the female grounding terminal 22 has a horizontal width (along the horizontal axis, i.e., the X-axis direction) that is smaller than the horizontal width (along the horizontal axis, i.e., the X-axis direction) of the female signal terminal 21. In other words, the female grounding terminal 22 is narrower and thinner than the female signal terminal 21. Furthermore, the horizontal width W1 of the grounding fixing section 223 of the female grounding terminal 22 is also smaller than the horizontal width W2 of the signal fixing section 213 of the female signal terminal 21. Thus, for the overall design of the female connector C1 (e.g., ... Figure 2 As shown, the grounding terminal 22 of the female terminal can avoid occupying too much terminal spacing, so that the signal terminal 21 of the female terminal can retain sufficient size to maintain impedance. At the same time, it can also reduce unnecessary parasitic coupling problems and greatly improve the flexibility and assembly efficiency of the metal terminal layout.

[0056] Furthermore, please refer to Figure 2 and Figure 6 As shown, one sidewall (e.g., the rear sidewall) of the female end insulating body 1 is provided with at least one groove 13. This groove 13 is recessed from the outside inwards, but is not limited to this. In this embodiment, the female end insulating body 1 is provided with multiple grooves 13, such that a support portion 132 can be formed between two adjacent grooves 13 to enhance the structural strength of the female end insulating body 1. Also, please refer to... Figure 7 As shown, one of the groove walls 131 of the groove 13 is inclined, and this inclined surface maintains a first angle θ1 with the vertical axis (Z-axis). Furthermore, the horizontal projection area of ​​the groove wall 131 extending along the longitudinal axis (Y-axis) corresponds to the signal relay segment 212 and / or the ground relay segment 222. When the female connector C1 is not yet inserted into the male connector C2, the female signal terminal 21 and the female ground terminal 22 remain in an unloaded state (e.g., ...). Figure 6 As shown), the signal relay segment 212 and the ground relay segment 222 have an inclined angle, but the aforementioned inclined angle is different from the first included angle θ1 and will be farther away from the inner wall of the female end insulating body 1.

[0057] Following on, please refer to Figure 1D and Figure 7As shown, when the female connector C1 is plugged into the male connector C2, the female metal terminals (female signal terminal 21, female ground terminal 22) are offset by the male metal terminals (male signal terminal 61, male ground terminal 62), causing their relay segments (signal relay segment 212, ground relay segment 222) to maintain a second angle θ2 with the vertical axis (Z-axis), and this second angle θ2 is substantially the same as the first angle θ1. Consequently, the signal relay segment 212 and the ground relay segment 222 are substantially parallel to the inclined surface. To ensure that the female metal terminals are substantially parallel to the inclined surface in the groove 13, in some embodiments, please refer to... Figure 1D and Figure 8 As shown, the inner wall surface of the female end insulating body 1 can maintain a third included angle θ3 with the vertical axis (Z-axis), which is substantially the same as the second included angle θ2 and the first included angle θ1. Thus, when the female end metal terminal is deflected by force, its relay section (signal relay section 212, grounding relay section 222) can abut against the inner wall surface of the female end insulating body 1, thereby maintaining the second included angle θ2 and substantially parallel to the inclined surface in the groove 13.

[0058] In conclusion, please refer to the following: Figure 1D and Figure 7 As shown, by designing the groove wall 131 of the groove 13 as an inclined surface, the spacing (thickness) between the female metal terminals (female signal terminal 21, female grounding terminal 22) and the female insulating body 1 can be kept as consistent as possible after being offset by force. This helps maintain a uniform electric field distribution around each of the female metal terminals, avoiding uneven electromagnetic coupling caused by variations in dielectric constant or thickness in some areas, thereby effectively reducing crosstalk interference. Furthermore, maintaining a consistent dielectric environment also helps maintain the stability of the characteristic impedance of the female signal terminal 21, thereby improving the stability of the overall electromagnetic environment, reducing signal reflection and distortion caused by impedance mismatch, improving signal integrity, and ensuring the reliability and performance of high-speed signal transmission. Please refer to... Figure 9 The simulation results of Far-End Crosstalk (FEXT) are shown in the test graph. The horizontal axis represents the frequency range from 0 GHz to 60 GHz, and the vertical axis represents the amplitude of the FEXT from -90 dB to 10 dB. For the 32 GHz FEXT test results, the test data using the groove 13 structure with an inclined surface as described in this application is -60.75 dB (as shown by the thick line), while the test data for a groove with a vertical inner wall (non-inclined surface) is -48.2 dB (as shown by the thin line). Therefore, it can be seen that the female connector C1 structure with the groove 13 with an inclined surface can more effectively suppress crosstalk and improve signal integrity.

[0059] Please refer to the following: Figure 2 and Figure 6 As shown, the female insulating body 1 has multiple through holes 12 on its sidewall. Each through hole 12 connects to the receiving space 10 and is located above the groove 13. The number of through holes 12 can be the same as the number of female metal terminals (but is not limited thereto), and they correspond to the positions of the female metal terminals. When the female connector C1 is inserted into the male connector C2, the female metal terminals are shifted by force, and their tips can extend into the corresponding through holes 12. In other words, each through hole 12 provides a space for the tip area of ​​the female metal terminal to move, preventing the female metal terminal from being affected by the inner wall of the female insulating body 1 and unable to form its predetermined offset angle (second included angle θ2). In addition, when the female insulating body 1 is installed in the female housing 3, the sidewall of the female housing 3 will cover each groove 13 (e.g., Figure 1B , Figure 6 (As shown).

[0060] Additionally, for ease of assembly, please refer to [link / reference]. Figures 2 to 3B , Figures 10A to 10B As shown, the female terminal group 2 also includes a terminal block 23, which can be injection molded to directly or indirectly cover a portion of the plurality of female signal terminals 21 and female ground terminals 22. Due to the design characteristics of the injection molding process, Figure 10A The space for accommodating the female signal terminal 21 and the female ground terminal 22 is not specifically shown. However, those skilled in the art will understand that the structure and arrangement of the terminal block 23, the female signal terminal 21, and the female ground terminal 22 are based on the characteristics of injection molding technology. Furthermore, please refer to... Figures 10A to 10B As shown, in this embodiment, the female connector C1 has two sets of female terminal groups 2. To effectively control the position and distance between each of the female terminal groups 2, the female connector C1 also has a relay connector 25, which is used to connect to the two terminal seats 23 to form a terminal assembly. Thus, by changing the thickness of the relay connector 25, the distance between each of the female terminal groups 2 can be effectively adjusted. However, depending on actual needs, in some embodiments, the relay connector 25 can connect to only one set of female terminal groups 2 to adjust the position of the female terminal group 2 in the female insulation body 1; or, in some embodiments, multiple female metal terminals can be assembled on the relay connector 25, which is equivalent to using the relay connector 25 as a terminal seat 23.

[0061] Please refer to the above. Figures 2 to 11BAs shown, the terminal block 23 has a plurality of seat fitting units 231 on one side, and the seat fitting unit 231 has a gradually changing cross-sectional shape; the relay connector 25 has a plurality of relay fitting units 251 on one side relative to the terminal block 23, and the cross-sectional shape of each relay fitting unit 251 matches the seat fitting unit 231. Therefore, the relay fitting unit 251 and the seat fitting unit 231 can be interlocked with each other, and the wedge-shaped shape features cause friction locking of the contact surfaces of the two, so that the relay connector 25 and the terminal block 23 are stably fixed together. Specifically, the configuration of the seat fitting unit 231 is a wedge-shaped protrusion. In this embodiment, the horizontal cross-sectional shape of the wedge-shaped protrusion is trapezoidal, and its length gradually widens outward from the direction of the terminal seat 23. The configuration of the relay fitting unit 251 is a wedge-shaped groove, and the configuration of the wedge-shaped groove is substantially the same as that of the wedge-shaped protrusion. The length of its horizontal cross-sectional shape gradually narrows outward from the direction of the relay coupling seat 25, but is not limited thereto.

[0062] In another embodiment of this application, please refer to Figures 12A to 12E In this configuration, the seat fitting unit 231 of the terminal block 23 has a cross-sectional shape with varying dimensions, for example, a T-shaped protrusion. The relay fitting unit 251 of the relay connector 25 is a T-shaped groove, and the aforementioned groove can penetrate the opposite two sides (front and rear sides) of the relay connector 25. Furthermore, each of the two terminal blocks 23 is also provided with at least one limiting block 235, which corresponds to a relay fitting unit 251 that is not its own seat fitting unit 231 that can extend into. In other words, the limiting block 235 of one terminal block 23 corresponds to the seat fitting unit 231 of the other terminal block 23. When multiple terminal blocks 23 are assembled to the front or rear side of the relay connector 25, each seat fitting unit 231 will engage with the corresponding relay fitting unit 251 from top to bottom and abut against the limiting block 235 of the non-own terminal block 23 (e.g., ...). Figure 12E (As shown), to enhance the assembly stability between the multiple terminal blocks 23 and the relay coupling unit 25. Furthermore, in other embodiments of this application, the configuration of the base fitting unit 231 and the relay fitting unit 251 is not limited to the aforementioned horizontal cross-sectional shape; or, the configurations of the base fitting unit 231 and the relay fitting unit 251 can be interchanged; or, their configurations can not be completely identical, but are sufficient for interlocking and fixing. In other words, as long as the base fitting unit 231 and the relay fitting unit 251 match each other and have cross-sectional shapes with varying dimensions, such that the geometric structure formed by the cross-sectional shapes in space can be mutually adapted, the base fitting unit 231 and the relay fitting unit 251 can be securely locked together for interlocking.

[0063] Furthermore, in order to maintain a good electromagnetic environment and prevent external noise from coupling into internal signals, please refer to [the relevant documentation] in this embodiment. Figure 2 , Figures 11A to 11B As shown, the female terminal group 2 can also be combined with a metal shield 24 to form a terminal assembly. The metal shield 24 is elongated and has multiple openings 240, each allowing the wedge-shaped protrusion to pass through and be smoothly assembled into the relay fitting unit 251. However, in other embodiments of this application, the terminal base 23 can use protrusions of different shapes and structures, not limited to wedge-shaped protrusions, depending on design or actual needs. In other words, the openings 240 of the metal shield 24 are geometrically designed to accommodate the connecting protrusions (including but not limited to wedge-shaped protrusions) on the terminal base 23, or to accommodate the relay fitting unit 251 of the relay fitting base 25 (such as a protrusion-type relay fitting unit 251), allowing the aforementioned protrusions to pass through.

[0064] As mentioned above, in this embodiment, please refer to... Figure 2 , Figures 11A to 11B As shown, the position of the opening 240 is substantially aligned with the female grounding terminal 22, and the position of the side wall area between two adjacent openings 240 is substantially aligned with the gap between two adjacent female signal terminals 21. Since the position of the metal shield 24 is close to the female metal terminal and can correspond to the gap between adjacent female signal terminals 21, it can block part of the electromagnetic coupling between adjacent female signal terminals 21. In addition, the metal shield 24 can be located between two sets of female terminal groups 2, further forming a shielding effect, so that the opposite female signal terminals 21 in the two sets of female terminal groups 2 are blocked by the metal shield 24, thereby improving the shielding efficiency. It should be noted here that the aforementioned "alignment" refers to the position between two structural features (such as: opening 240 and female grounding terminal 22, side wall area and gap, etc.), and is not limited to the case of direct alignment, but also includes offset or lateral correspondence within a certain tolerance range. In other words, as long as the aforementioned effective shielding or isolation effect can be achieved, it is considered a state of effective alignment.

[0065] Please refer to the following: Figure 2 , Figures 11A to 11BAs shown, to enhance the assembly stability between the terminal block 23 and the metal shield 24, the terminal block 23 has multiple recesses 233 on one side; the metal shield 24 has multiple protrusions 242, each of which can extend into a corresponding recess 233, and at least some of the protrusions 242 are arranged with openings 240 along the vertical axis (Z-axis). Thus, through the design of the protrusions 242 and recesses 233, the metal shield 24 can be conveniently installed onto the terminal block 23 without easily deviating from the intended installation position. In this embodiment, the metal shield 24 forms each protrusion 242 by bending and deforming itself, but this is not a limitation. Furthermore, the positions of the connecting protrusions of the terminal block 23 (such as the seat fitting unit 231) and the openings 240 and recesses 233 of the metal shield 24 can correspond to the female grounding terminal 22, so as to reduce the dielectric environment (such as the change in dielectric layer thickness) that affects the location of the female signal terminal 21.

[0066] Please also refer to Figure 2 , Figures 10A to 11B As shown, in this embodiment, the metal shield 24 is further provided with a plurality of elastic arms 244, each of which can contact the female grounding terminal 22 to enhance the grounding and shielding effect of the metal shield 24 in application. In this embodiment, the elastic arms 244 are arranged with openings 240 along the vertical axis (Z-axis) to avoid accidental contact with the female signal terminal 21. In addition, the metal shield 24 may be provided with at least one hole 246, which corresponds to the female grounding terminal 22, and is used to inject liquid solder until the solder hardens, so that the solder, the metal shield 24 and the female grounding terminal 22 are electrically connected. At the same time, it can also ensure a tight connection between the metal shield 24 and the female grounding terminal 22 to maintain good electrical performance, but it is not limited thereto.

[0067] Please see Figures 1A to 1D , Figure 13 As shown, in this embodiment, the male connector C2 includes a male insulating body 4, a mating portion 5, and a male terminal group 6. The mating portion 5 is plate-shaped and fixed to the male insulating body 4 along the vertical axis (Z-axis). Depending on actual needs, the mating portion 5 can be integrally formed on the male insulating body 4, or it can be a separate component assembled to the male insulating body 4. Furthermore, the configuration of the mating portion 5 is adapted to the mating interface 11 of the female connector C1; therefore, it can extend into the receiving space 10 of the female connector C1 through the mating interface 11.

[0068] Please refer to the above. Figure 13As shown, the male terminal group 6 includes multiple male metal terminals, and these multiple male metal terminals are disposed on the mating portion 5. Specifically, the male metal terminals can be classified into male signal terminals 61 and male ground terminals 62. In this embodiment, the male connector C2 has two sets of male terminal groups 6, one set of which is disposed on the front side of the mating portion 5, and the other set of which is disposed on the rear side of the mating portion 5. The male signal terminals 61 and male ground terminals 62 in the same set of male terminal groups 6 are arranged along the horizontal axis (X-axis). Since the arrangement and configuration of the two sets of male terminal groups 6 are substantially the same or similar, and they are only disposed on different sides of the mating portion 5, only one set of male terminal groups 6 will be described below.

[0069] Also, please see Figures 13 to 15 As shown, at least two male ground terminals 62 in the male terminal group 6 have at least one male signal terminal 61 (two male signal terminals 61 in this embodiment), and the bottoms of the aforementioned two male ground terminals 62 are connected as one piece along the horizontal axis (X-axis) to form a contact area 63. This contact area 63 extends to cover the front side of the mating portion 5 and further bends to extend to the bottom surface of the mating portion 5, covering at least one-third of the bottom surface of the mating portion 5. The horizontal width of the contact area 63 is greater than the horizontal width of any male signal terminal 61, but is not limited thereto. In other embodiments of this application, the contact area 63 may only cover the bottom surface of the mating portion 5.

[0070] In this embodiment, please refer again. Figures 13 to 15As shown, the bottoms of multiple male grounding terminals 62 are connected as one unit to form multiple grounding areas 63. However, this is not a limitation. In some embodiments of this application, the bottoms of all male grounding terminals 62 are connected as one unit to form a single grounding area 63. Furthermore, the length M1 (extending length along the vertical axis (Z-axis)) of the grounding area 63 on the front side of the mating portion 5 is greater than or equal to the length M2 (extending length along the longitudinal axis (Y-axis)) of the grounding area 63 on the bottom surface of the mating portion 5, thus forming a significant and large area. Additionally, the male grounding terminals 62 of the two sets of male terminal groups 6 located on different sides of the mating portion 5 extend to the grounding area 63 on the bottom surface of the mating portion 5, but do not connect or contact each other. Thus, by virtue of the large width and area of ​​the grounding area 63 and its structural design extending to the bottom surface, the male grounding terminal 62 and the grounding area 63 together form an enveloping shielding structure to create effective electromagnetic shielding around the adjacent male signal terminal 61, thereby reducing external interference to the male signal terminal 61 and suppressing crosstalk effects during signal transmission. Furthermore, the extended configuration of the grounding area 63 facilitates contact with the elastic arm 244 of the female connector C1, ensuring a stable grounding connection between the two, further optimizing electromagnetic compatibility (EMC) and improving signal integrity.

[0071] To improve the shielding effect between the two sets of male terminal blocks 6, please refer to [the relevant documentation]. Figures 13 to 15 As shown, in this embodiment, the mating portion 5 is provided with at least one metal barrier 51, and the metal barrier 51 is in direct contact with at least a portion of the male ground terminal 62 (but not limited thereto), thereby forming an effective shielding barrier to reduce electromagnetic coupling between adjacent male signal terminals 61, which helps to reduce crosstalk interference and improve signal integrity. Furthermore, the metal barrier 51 not only directly contacts the male ground terminal 62, but also connects with the metal shield 24 in the female connector C1, further enhancing the electromagnetic compatibility (EMC) of the overall system. This ensures effective grounding and electromagnetic shielding, which is crucial for the stable transmission of high-speed signals and further improves the connector assembly C's resistance to external interference.
