After continuous research, design, and repeated trial of samples and improvement, the present utility model is finally created, which has practical value.

[0063] Please refer to Figures 1-4 The connector is specially designed to effectively resist electromagnetic crosstalk, and mainly consists of two core components: two rows of terminal groups 1 and a metal middle piece 2 located therebetween.

[0064] Firstly, the two rows of terminal groups 1 are arranged in an upper and lower spaced form, which is designed to ensure that the two rows of terminal groups 1 can realize normal electrical connection for signal transmission, and also provides sufficient space for the subsequent introduction of the metal middle piece 2 to fully play its physical isolation function.

[0065] Subsequently, the metal middle piece 2, as the key innovation point in this embodiment, is ingeniously placed between the two rows of terminal groups 1. This intermediate layer of metal material not only has excellent electrical conductivity and shielding performance, but also can absorb, reflect and counteract external electromagnetic interference, thereby protecting the two rows of terminal groups 1 from electromagnetic crosstalk. Moreover, hollow areas 3 are ingeniously arranged on the surface of the metal middle piece. This hollow design not only maintains the overall structural strength of the metal middle piece, but also further optimizes its electromagnetic shielding effect, enabling the metal middle piece to more flexibly adapt to different electromagnetic environments and effectively reduce unnecessary electromagnetic interference.

[0066] The core advantage of this embodiment lies in the effective physical isolation of electromagnetic crosstalk between the two rows of terminal groups 1 achieved by the introduction of the metal middle piece 2 and the hollow areas 3 thereon. This design not only significantly improves the electromagnetic compatibility of the connector, but also maximizes the integrity and accuracy of signal transmission, providing a solid guarantee for stable signal transmission.

[0067] It can be understood that each row of terminal groups 1 is composed of multiple signal terminals arranged side by side. This design not only ensures the precise alignment and close cooperation between the signal terminals, but also provides a stable and efficient signal transmission channel for the connector. Each signal terminal carries a specific electrical function, and they work together to meet the needs of electronic devices for data transmission, power connection or other signal transmission. This structured terminal group design not only improves the overall performance of the connector, but also ensures its stable operation in complex electromagnetic environments.

[0068] Please refer again to Figure 3 to gain a deeper understanding of a specific and optimized implementation of the connector against electromagnetic crosstalk in this embodiment. In this implementation, one notable detail is that the hollow areas 3 are not randomly distributed on the metal middle piece 2, but are carefully arranged in the middle region of the metal middle piece 2.

[0069] Placing the hollow areas 3 in the middle of the metal middle piece 2 involves a thoughtful consideration behind this design decision. First, the middle position is usually the area where electromagnetic fields are most concentrated and interference is most severe between the two rows of terminal groups 1. Therefore, placing hollow areas here can more effectively block the propagation path of electromagnetic interference, thereby significantly improving the effect of electromagnetic shielding.

[0070] Secondly, the design of middle hollow helps to maintain the overall structural strength of the metal middle piece 2, avoiding deformation or damage when subjected to external forces, thereby ensuring the stability and reliability of the connector during long-term use.

[0071] Moreover, this design also fully demonstrates the exquisite skills in detail processing and deep understanding of electromagnetic compatibility of the embodiment. By accurately positioning the hollow area 3 in the middle of the metal middle piece 2, not only more efficient electromagnetic shielding can be achieved, but also the structure and function of the connector can be further optimized without affecting the overall performance of the connector.

[0072] In summary, the ingenious design of the position of the hollow area 3 in the embodiment not only enhances the electromagnetic shielding performance of the connector, but also improves the structural strength and stability.

[0073] Please refer again to Figure 4 In an embodiment of the embodiment, the design of the metal middle piece 2 is particularly unique, which is composed of two arm parts 201 and two connecting parts 202. This structure not only enhances the flexibility and adaptability of the metal middle piece 2, but also lays a solid foundation for its more efficient role in electromagnetic shielding.

[0074] Specifically, the two arm parts 201 are designed to be spaced apart and are ingeniously located on the left and right sides of the terminal group 1. Such a layout enables the arm parts 201 to closely fit the side edges of the terminal group 1, thereby more effectively blocking the propagation path of electromagnetic interference.

[0075] At the same time, the two connecting parts 202 are also designed to be spaced apart, which are respectively located between the two arm parts 201 and form a stable structural framework by connecting the two arm parts 201. This design not only enhances the overall stability of the metal middle piece 2, but also provides more reliable protection for its electromagnetic shielding.

[0076] More noteworthy is the ingenious cooperation of the two arm parts 201 and the two connecting parts 202 in layout, which together enclose a unique hollow area 3. This hollow area 3 not only optimizes the electromagnetic shielding effect of the metal middle piece 2, but also provides a more flexible and efficient solution for dealing with complex electromagnetic environments.

[0077] Please refer again to Figure 4 In an embodiment of the embodiment, the arm part 201 of the metal middle piece 2 is designed to be more complex and functional, that is, a hole 4 is provided on the arm part 201 near the hollow area 3.

[0078] This design detail not only reflects the deep consideration of the electromagnetic shielding performance of the connector, but also demonstrates the ingenious design in structure. The setting of the hole 4 can further optimize the electromagnetic shielding effect of the metal middle piece 2, and by adjusting the size, shape and distribution of the hole, the distribution of the electromagnetic field and the propagation path of the interference can be more effectively controlled, thereby achieving more precise and efficient shielding of electromagnetic interference.

[0079] On the other hand, the introduction of the holes 4 also provides the metal middle piece 2 with more flexible structural characteristics. These holes can act as stress release points, helping to alleviate stress concentration of the metal middle piece when subjected to external forces, thereby enhancing the overall durability and reliability of the connector.

[0080] In addition, the design of the holes 4 can also have a positive impact on the heat dissipation performance of the connector. During the operation of electronic equipment, the connector will generate heat due to the passage of current. By providing holes on the metal middle piece, the area for heat exchange can be increased, helping to quickly dissipate heat and maintain stable operation of the connector.

[0081] In summary, the arrangement of the holes 4 on the arm portion 201 in this embodiment not only improves the electromagnetic shielding performance of the connector, but also enhances its structural strength and heat dissipation performance.

[0082] Please refer to Figures 5-8 In one embodiment of this embodiment, the design of the connector is further enriched and perfected, especially by introducing the first insulator 5, the second insulator 6 and the third insulator 7, which not only improves the overall structural stability of the connector, but also optimizes its electromagnetic shielding performance and assembly convenience.

[0083] First, the first insulator 5 and the second insulator 6 are designed to be arranged in an upper-lower stacking manner. This layout allows the two rows of terminal groups 1 to be inserted into the first insulator 5 and the second insulator 6 respectively, thereby achieving effective support and fixation of the corresponding terminal groups. At the same time, this stacking design also helps to reduce the overall size of the connector, meeting the demand for miniaturization and integration of modern electronic equipment.

[0084] Secondly, the addition of the third insulator 7 provides a more stable fixing environment for the connector. The fixing cavity provided in the third insulator can accommodate the first insulator 5 and the second insulator 6, and through the extension into the fixing cavity, it achieves effective fixation and limiting of the two. This design not only enhances the overall structural strength of the connector, but also helps to improve its stability and reliability in complex electromagnetic environments.

[0085] More noteworthy is that in this embodiment, protrusions 16 that can cooperate with the holes 4 for clamping are provided on the first insulator 5 and / or the second insulator 6 at positions corresponding to the holes 4. This design detail achieves a firm connection between the insulator and the metal middle piece 2, effectively preventing the metal middle piece 2 from shifting or deforming when subjected to external forces, thereby ensuring the long-term stable operation of the connector.

[0086] In summary, the design of the first, second and third insulators 5, 6 and 7, as well as the cooperation between the protrusion 16 and the hole 4, not only improves the structural stability of the connector, but also optimizes the assembly convenience and long-term reliability.

[0087] Please refer to Figures 5-8 In one embodiment of the present embodiment, the unique design of the anti-electromagnetic interference connector is further analyzed, i.e. the cooperation between the bent portion 8 formed by bending the rear end of the arm portion 201 and the third insulator 7.

[0088] In this embodiment, the arm portion 201 of the metal middle piece 2 is ingeniously designed to form a bent portion 8 at the rear end. This bending design not only enhances the structural strength of the arm portion 201, but also provides a more reliable way for its fixed connection with the third insulator 7. The introduction of the bent portion 8 enables the metal middle piece 2 to be more stably embedded in the third insulator 7, effectively preventing the metal middle piece from loosening or shifting during the use of the connector.

[0089] At the same time, the design of the bent portion 8 also takes into account the assembly convenience of the connector. Through the cooperation of the bent portion 8 and the third insulator 7, the assembly process of the connector can be simplified, the assembly efficiency can be improved, and the assembly cost can be reduced.

[0090] Please refer to Figures 9-10 In one embodiment of the present embodiment, the connector further comprises an outer shell 9 and an inner shell 10;

[0091] In this embodiment, the inner shell 10 serves as the core support structure of the connector, and the third insulator 7 is embedded in the cavity of the inner shell 10, thereby achieving effective fixation and protection of the third insulator and its internal components. The design of the inner shell 10 not only enhances the overall structural strength of the connector, but also provides a more stable support foundation, and helps to further isolate external electromagnetic interference, thereby improving the electromagnetic compatibility of the connector.

[0092] The outer shell 9 is sleeved on the outer surface of the inner shell 10, forming a second layer of protection for the connector. The introduction of the outer shell 9 improves the appearance and durability of the connector.

[0093] More noteworthy is that the rear end of the inner shell 10 is designed with a first plug-in foot 11 that can enhance the stability of the connection on the PCB board. The first plug-in foot 11 is a downwardly bent structure, which enables the connector to be more stably fixed when inserted into the PCB board, effectively preventing the connector from loosening or falling off during long-term use. At the same time, the bent structure of the first plug-in foot 11 can also provide better mechanical support, enhancing the connection strength and stability of the connector on the PCB board.

[0094] In summary, the design of the outer shell 9 and the inner shell 10, as well as the introduction of the first plug-in leg 11, not only enhances the structural strength and electromagnetic compatibility of the connector, but also significantly improves its connection stability on the PCB board and long-term reliability.

[0095] In one embodiment of the present embodiment, the outer shell 9 is designed to be plastic, while the inner shell 10 is made of metal. This design choice not only reflects a deep understanding of the performance requirements of the connector, but also demonstrates a subtle consideration in material selection.

[0096] The plastic outer shell 9 has the advantages of light weight, low cost, and easy processing. It can provide the necessary protection and support for the connector while maintaining a relatively light overall weight, which helps to meet the demand for lightweight in modern electronic devices.

[0097] The metal inner shell 10 can provide a more stable support structure for the connector, effectively resisting external impact and vibration. At the same time, the metal inner shell can also act as an electromagnetic shielding layer, further blocking the propagation path of electromagnetic interference and improving the overall electromagnetic shielding effect of the connector.

[0098] The material selection of the outer shell 9 and the inner shell 10 not only plays its unique performance advantages, but also cooperates with each other to improve the overall performance of the connector. The lightweight and insulating properties of the plastic outer shell 9 and the high strength and electromagnetic shielding properties of the metal inner shell 10 complement each other, so that the connector not only maintains lightweight, but also has excellent structural strength and electromagnetic compatibility.

[0099] Please refer to Figures 9-10 again, and in combination with reference to Figures 11-12 In one embodiment of the present embodiment, the connector further comprises two fixing members 12;

[0100] In this embodiment, the connector is ingeniously designed to include two fixing members 12, which are integrally formed on both sides of the outer shell 9. This design not only enhances the overall structural strength of the connector, but also provides a more stable fixing method.

[0101] The front end of the fixing member 12 is designed with a second plug-in leg 13 that can enhance the connection stability on the PCB board. Similar to the first plug-in leg 11 at the rear end of the inner shell 10, the second plug-in leg 13 also adopts a downward bending structure. This design allows the connector to form a more secure fixed connection with the PCB board through the second plug-in leg 13 when inserted into the PCB board, effectively preventing the connector from loosening or falling off during long-term use. At the same time, the bending structure of the second plug-in leg 13 can also provide better mechanical support, further enhancing the connection strength and stability of the connector on the PCB board.

[0102] More noteworthy is that the rear end of the fixing member 12 is also designed with two upper and lower inwardly extending clamping portions 14. The two clamping portions 14 can cleverly clamp the third insulator 7 inwardly, thereby achieving effective fixation and protection of the third insulator 7 and its internal components. Such clamping design not only simplifies the assembly process of the connector, improves the assembly efficiency, but also helps to reduce the assembly cost.

[0103] Please refer again to Figure 12 In an embodiment of the embodiment, the connector further comprises a waterproof ring 15.

[0104] The waterproof ring 15 is sleeved on the outer surface of the front end of the third insulator 7.

[0105] It should be noted that the addition of the waterproof ring 15 provides additional waterproof protection for the connector, which can effectively prevent harmful factors such as water and moisture from entering the interior of the connector during electrical connection, thereby ensuring the long-term stable operation of the connector.

[0106] The waterproof ring 15 is usually made of elastic materials such as rubber or silicone, which have good sealing performance and weather resistance, and can maintain stable waterproof effect in various harsh environments. When the connector is inserted into the corresponding socket or interface, the waterproof ring 15 can tightly fit the edge of the socket or interface, forming an effective waterproof barrier to prevent water from seeping between the connector and the socket.

[0107] In addition, the design of the waterproof ring 15 also takes into account the assembly convenience and cost-effectiveness of the connector. By simply sleeving, the waterproof ring 15 can be installed on the front end of the third insulator 7 without the need for additional fixing or bonding steps, thereby reducing the assembly cost and improving the assembly efficiency.

[0108] In summary, the design of the waterproof ring 15 in the embodiment not only enhances the waterproof performance of the connector, but also optimizes its assembly convenience and cost-effectiveness.

[0109] Although the terms such as terminal group and metal middle piece are used more in this application, the possibility of using other terms is not excluded. The use of these terms is only to facilitate the description and explanation of the essence of the utility model; any additional limitation is contrary to the spirit of the utility model.
