[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] refer to Figures 1 to 4 The connector provided in this embodiment, which reduces high-frequency resonance, includes a housing 1 and a mounting base 2 installed inside the housing 1. A first terminal assembly 3 and a second terminal assembly 4 are symmetrically arranged on the mounting base 2, and a middle clip 5 is provided between the first terminal assembly 3 and the second terminal assembly 4. In some embodiments, the housing 1 and the mounting base 2 are snap-fitted together, and the first terminal assembly 3, the second terminal assembly 4, and the middle clip 5 can be fixed to the mounting base 2 by injection molding.

[0040] Mounting base 2 includes base 21 and extension 22 located at the top of base 21. First terminal assembly 3, second terminal assembly 4 and middle clip 5 all pass through base 21 and extension 22. An EMI pad 23 is provided on each of opposite sides of extension 22, and the first terminal assembly 3, second terminal assembly 4 and middle clip 5 are all located between two EMI pads 23.

[0041] A first grounding portion 231 is formed on the EMI pad 23. The first grounding portion 231 is exposed on the outer surface of the extension 22 and is used to contact the housing 1. In one embodiment, the first grounding portion 231 is formed by extending and bending from the edge of the EMI pad 23 in a direction perpendicular to the EMI pad 23, and the two EMI pads 23 are symmetrically arranged.

[0042] Understandably, EMI pads 23 are provided on both sides of the extension 22, so that the first terminal assembly 3, the second terminal assembly 4, and the middle clip 5 are located between the two EMI pads. This not only resists interference from external devices on the signal transmission of the first terminal assembly 3 and the second terminal assembly 4, but also prevents the first terminal assembly 3 and the second terminal assembly 4 from interfering with external devices during signal transmission. This effectively prevents mutual interference and influence between the connector and external devices, ensuring the normal and stable use of the connector. Through the contact between the first grounding part 231 of the EMI pad 23 and the housing 1, the high-frequency resonance of the connector can be effectively reduced, minimizing the adverse effects of high-frequency resonance on the connector, ensuring the normal performance of the connector, and improving the stability of the connector's signal transmission.

[0043] In some embodiments, the first terminal assembly 3 includes a plurality of first transmission terminals 31 arranged at equal intervals and first grounding terminals 32 located at both ends of the plurality of first transmission terminals 31. The second terminal assembly 4 includes a plurality of second transmission terminals 41 arranged at equal intervals and second grounding terminals 42 located at both ends of the plurality of second transmission terminals 41.

[0044] As a further optimization, a first connecting portion 51 is formed by extending outward from the side of the middle clip 5, a second connecting portion 321 is formed by extending outward from the side of the first grounding terminal 32, and a third connecting portion 421 is formed by extending outward from the side of the second grounding terminal 42. The second connecting portion 321 and the third connecting portion 421 are respectively connected to opposite sides of the first connecting portion 51, and the first connecting portion 51 abuts against the inner wall of the extension portion 22. In some embodiments, the connection between the first connecting portion 51 and the second connecting portion 321, and between the first connecting portion 51 and the third connecting portion 421, can be laser spot welding, and the second connecting portion 321 and the third connecting portion 421 can also abut against the inner wall of the extension portion 22.

[0045] By connecting the first connecting part 51 to the second connecting part 321 and then grounding them, and by connecting the first connecting part 51 to the third connecting part 421 and then grounding them, the high-frequency resonance of the connector can be effectively reduced, the signal transmission rate of the connector can be improved, thereby improving the transmission performance of the connector. At the same time, the anti-interference capability of the connector can also be improved, and the normal performance of the connector can be maintained.

[0046] The middle clip 5 also has a second grounding portion 52 and a third grounding portion 53 formed on its side. The second grounding portion 52 extends outward from the side of the middle clip 5, and the third grounding portion 53 extends outward from the bottom edge of the middle clip. The second grounding portion 52 and the third grounding portion 53 are located above and below the first connecting portion 51, respectively. The end of the second grounding portion 52 is exposed on the outer surface of the extension portion 22 for contact with the outer shell 1, and the third grounding portion 53 is exposed at the bottom end of the base portion 21 for grounding after connection with the PCB board. By grounding the second grounding portion 52 and the third grounding portion 53 after connection with the outer shell 1 and the PCB board, respectively, the high-frequency resonance of the connector can be further reduced, the adverse effects of high-frequency resonance on the connector can be reduced, and the anti-interference capability of the connector can be further improved, thus enhancing the overall performance of the connector.

[0047] The connector in this embodiment, which reduces high-frequency resonance, improves its anti-interference capability by setting an EMI gasket, while also preventing the connector from interfering with external devices. The contact between the first grounding part and the housing reduces high-frequency resonance, maintaining the overall stability of the connector's performance. By grounding the first connecting part after connecting to the second connecting part, and then grounding the first connecting part after connecting to the third connecting part, the high-frequency resonance of the connector is reduced, signal transmission efficiency is improved, and the connector's anti-interference capability is also enhanced. The middle clip, after being grounded by connecting to the housing and the PCB board through the second and third connecting parts respectively, further reduces high-frequency resonance and improves the overall performance of the connector.

[0048] Example 2

[0049] As a further optimization of Example 1, refer to Figures 5 to 6 Both the first transmission terminal 31 and the first grounding terminal 32 are provided with a first contact end 33 and a first fixed end 34, and both the second transmission terminal 41 and the second grounding terminal 42 are provided with a second contact end 43 and a second fixed end 44. The first contact end 33 and the second contact end 43 are both located in the extension 22 and exposed at the top of the extension 22, while the first fixed end 34 and the second fixed end 44 are both located in the base 21. It should be noted that the heights of different first contact ends 33 may be the same or different, and the heights of different second contact ends 43 may be the same or different, but each first contact end 33 is at the same height as its corresponding second contact end 43.

[0050] In this embodiment, the top of the extension 22 is higher than the first contact end 33, the second contact end 43 and the middle clip 5. The top of the middle clip 5 is embedded inside the top of the extension 22. The first contact end 33 and the second contact end 43 are exposed on opposite sides of the top of the extension 22. The ends of the first fixing end 34 and the second fixing end 44 both extend out of the bottom of the base 21 and are connected to the PCB board.

[0051] In some embodiments, the top of the middle clip 5 is at a height of H1, and the tops of the first terminal assembly 3 and the second terminal assembly 4 are both at a height of H2, where H1 > H2. This improves the mechanical strength, durability, and lifespan of the connector, while also allowing for better control of current flow, reduced resistance, and increased conductivity.

[0052] The middle clip 5 has a cutout portion 54 at its top, located between the first contact end 33 and the second contact end 43. The top of the extension 22 has a clearance through hole corresponding to the position of the cutout portion 54. The cutout portion 54 in the middle clip 5 can improve the transmission performance of the first contact end 33 and the second contact end 43 during high-frequency and high-speed transmission, thereby improving the signal transmission rate and stability of the connector.

[0053] The connector in this embodiment, which reduces high-frequency resonance, improves the connector's durability and lifespan by setting the height of the middle clip to be higher than that of the first and second terminal assemblies, while also increasing conductivity. Furthermore, by creating a cutout at the top of the middle clip, the connector's performance during high-frequency and high-speed transmission is improved, thereby enhancing signal transmission efficiency and stability.

[0054] Example 3

[0055] As a further optimization of Example 1, refer to Figure 7 The top of the outer shell 1 has a height of H3, and the top of the mounting base 2 has a height of H4, where H3 > H4. This provides better protection for the first terminal assembly 3 and the second terminal assembly 4, preventing them from being easily scratched or damaged due to exposure to the outside environment, thus ensuring the normal performance of the connector.

[0056] The outer shell 1 has elastic buckles 11 on its two inner sidewalls. The extension 22 has a buckle groove 221 corresponding to the position of the elastic buckle 11, and the elastic buckle 11 is engaged in the buckle groove 221. In this embodiment, the elastic buckle 11 is a U-shaped spring. When the outer shell 1 is fitted into the mounting base 2, the elastic buckle 11 deforms due to the pressure from the outer sidewall of the extension 22. When the elastic buckle 11 reaches the position of the buckle groove 221, it springs back and resets due to the absence of pressure, thus engaging in the buckle groove 221. This achieves the connection and fixation between the outer shell 1 and the mounting base 2, and the connection is stable and not easy to loosen during the insertion and removal of the connector.

[0057] In some embodiments, a limiting block 12 is also provided on the side wall of the housing 1, and a limiting groove 211 is formed on the base 21 corresponding to the position of the limiting block 12. In this embodiment, the limiting groove 211 is formed by the top end of the base 21 recessed towards the bottom end of the base 21, and the limiting block 12 is engaged in the limiting groove 211, thereby further limiting the displacement of the housing 1 on the mounting base 2, which is beneficial to improving the overall connection stability of the connector and ensuring stable signal transmission.

[0058] In some embodiments, the bottom of the housing 1 extends outward to form solder feet, which can be used to connect and fix the housing 1 to the PCB board.

[0059] The connector provided in this embodiment, which reduces high-frequency resonance, provides better protection for the first and second terminal assemblies by setting the outer shell higher than the mounting base, ensuring the normal performance of the connector. The cooperation between the elastic snap and the snap groove improves the connection stability between the outer shell and the mounting base. The cooperation between the limiting block and the limiting groove further limits the outer shell, thereby further improving the overall connection stability of the connector.
