[0035] The utility model is further described below in conjunction with specific embodiments and drawings.

[0036] See Figure 1-15 As shown, a high-speed connector comprises an insulating seat 1 and a plurality of signal terminals 2 and a plurality of grounding terminals 3, wherein the signal terminals 2 and the grounding terminals 3 are respectively inserted and fixed in a first terminal slot 11 and a second terminal slot 12 of the insulating seat 1.

[0037] A plurality of slots 10 are arranged on the upper end of the insulating seat 1, and a plurality of first terminal slots 11 and second terminal slots 12 are arranged on both sides of each slot 10. A row of terminals is arranged on both sides of each slot 10, and each row of terminals includes a plurality of signal terminals 2 and a plurality of ground terminals 3.

[0038] The grounding terminal 3 in the present invention is different from the grounding terminal in the background technology. Specifically, each of the grounding terminals 3 includes a first grounding terminal 31 and a second grounding terminal 32 that are independent of each other, and a grounding plate 33, wherein each of the first grounding terminals 31 has a first elastic conductive arm 311 and a first pin portion 312; each of the second grounding terminals 32 has a second elastic conductive arm 321 and a second pin portion 322; the first and second pin portions both extend out of the lower end surface of the insulating seat 1, and the first and second elastic conductive arms are both exposed in the matching slot 10 provided at the upper end of the insulating seat 1. The inner wall of the matching slot 10 is provided with a first avoidance groove 101 and a second avoidance groove 102 that respectively provide sufficient space for the first elastic conductive arm 311 and the second elastic conductive arm 321 to generate elastic deformation. When the first elastic conductive arm 311 and the second elastic conductive arm 321 come into contact with the terminal of the mating connector, the first elastic conductive arm 311 and the second elastic conductive arm 321 will both produce elastic deformation and move backwards. At this time, the first elastic conductive arm 311 and the second elastic conductive arm 321 are respectively accommodated in the first avoidance groove 101 and the second avoidance groove 102, thereby preventing the first elastic conductive arm 311 and the second elastic conductive arm 321 from having insufficient space to produce elastic deformation and form a stable conductive connection with the terminal of the mating connector.

[0039] When the grounding terminal 3 in the present invention is assembled, the first grounding terminal 31 and the second grounding terminal 32 are both inserted into the same second terminal groove 12, and the grounding plate 33 is also inserted and fixed in the second terminal groove 12, and is embedded between the first grounding terminal 31 and the second grounding terminal 32, and respectively drives the first grounding terminal 31 and the second grounding terminal 32 to move outward to be clamped and positioned with the inner wall of the second terminal groove 12; that is, the present invention divides a grounding terminal 3 into three independent, smaller parts, specifically the first grounding terminal 31, the second grounding terminal 32 and the grounding plate 33, so that the grounding terminal can be made of smaller materials. , which is more convenient to manufacture; during assembly, first insert the first grounding terminal 31 and the second grounding terminal 32 into the same second terminal slot 12, and finally insert and fix the grounding plate 33 into the second terminal slot 12, and embed it between the first grounding terminal 31 and the second grounding terminal 32, and respectively drive the first grounding terminal 31 and the second grounding terminal 32 to move outward to hold and position with the inner wall of the second terminal slot 12, and make the first and second grounding terminals conductive, so as to ensure that the first grounding terminal 31 and the second grounding terminal 32 are stably installed in the insulating seat 1, and are extremely firm. During the plug-in use process, there will be no phenomenon of the grounding terminal retreating, thereby ensuring the quality of the product. At the same time, the grounding terminal 3 will not scratch the inner wall of the second terminal slot 12 during the assembly process, that is, it will not form plastic debris or burrs on the inner wall of the second terminal slot 12, and there is no need to add additional steps for processing, which improves production efficiency and ensures product quality.

[0040] A plurality of first convex bumps 313 are formed on one side of the first grounding terminal 31 close to the second grounding terminal 32 and are spaced apart in the longitudinal direction. A plurality of second convex bumps 323 are formed on one side of the second grounding terminal 32 close to the first grounding terminal 31, and the two side surfaces of the grounding sheet 33 are respectively in contact with the first convex bumps 313 and the second convex bumps 323. In other words, the grounding sheet 33 and the first grounding terminal 31 and the second grounding terminal 32 are in contact at multiple points, which can form better contact and better stability, thereby enabling the grounding sheet 33 to better tension and position the first grounding terminal 31 and the second grounding terminal 32, so that the first grounding terminal 31 and the second grounding terminal 32 are more stably fixed in the second terminal slot 12 of the insulating seat 1, thereby ensuring the stability and firmness of the assembly structure.

[0041] The cross sections of the first convex hump 313 and the second convex hump 323 are both arc-shaped, and the first convex hump 313 and the second convex hump 323 are symmetrically distributed.

[0042] A first barb 314 is provided on one side of the first grounding terminal 31 away from the second grounding terminal 32; a second barb 324 is provided on one side of the second grounding terminal 32 away from the first grounding terminal 31. The first barb 314 and the second barb 324 move toward the inner walls on both sides of the second terminal slot 12 under the action of the grounding sheet 33, so that the first barb 314 and the second barb 324 are respectively clamped and positioned with the inner walls on both sides of the second terminal slot 12, thereby ensuring the stability of the assembly structure, and its interference ability is stronger, and the stability of the assembly structure can be ensured.

[0043] A first elastic hole 315 is provided on a side of the first grounding terminal 31 close to the first convex bump 313, so that a first elastic portion 316 capable of elastic deformation is formed on one side of the first grounding terminal 31, and both ends of the first elastic portion 316 are integrally connected to the first grounding terminal 31, and the first convex bump 313 is formed on the outer side of the first elastic portion 316; a second elastic hole 325 is provided on a side of the second grounding terminal 32 close to the second convex bump 323, so that a second elastic portion 326 capable of elastic deformation is formed on one side of the second grounding terminal 32, and both ends of the second elastic portion 326 are integrally connected to the second grounding terminal 32, and the second convex bump 323 is formed on the outer side of the second elastic portion 326. That is to say, the first grounding terminal 31 is formed with a first elastic part 316 that can generate elastic deformation, and the second grounding terminal 32 is formed with a second elastic part 326 that can generate elastic deformation. The first elastic part 316 and the second elastic part 326 are respectively in contact with the two side surfaces of the grounding plate 33, so that elastic contact is formed therebetween, thereby avoiding the problem that the grounding plate 33 cannot be inserted between the first grounding terminal 31 and the second grounding terminal 32, and ensuring assembly efficiency. At the same time, after the grounding plate 33 is inserted between the first grounding terminal 31 and the second grounding terminal 32, the first barb 314 of the first grounding terminal 31 and the second barb 324 of the second grounding terminal 32 can be respectively clamped and positioned with the inner walls of the two sides of the second terminal slot 12, and the positioning is elastic clamping, and the positioning effect is better.

[0044] The first and second guiding slopes 331 and 332 are respectively provided on both sides of the upper end of the grounding plate 33 for guiding the insertion between the first grounding terminal 31 and the second grounding terminal 32. The first and second guiding slopes 331 and 332 are distributed in an eight-shaped shape. When the grounding plate 33 is inserted between the first and second grounding terminals 31 and 32, the first and second guiding slopes 331 and 332 first contact the first and second convex bumps 313 and 323, respectively, which can play a good guiding role, so that the grounding plate 33 can be better inserted between the first and second grounding terminals 31 and 32 as a whole, and its assembly efficiency is higher.

[0045] The insulating seat 1 is provided with an embedding groove 13 which is connected to the second terminal groove 12 and is vertically distributed with the second terminal groove 12. The grounding plate 33 is embedded and fixed in the embedding groove 13, and its assembly structure is extremely simple. The grounding plate 33 is L-shaped, and has a space-avoiding groove 333 at its upper end. The groove wall of the space-avoiding groove 333 corresponds to the groove wall of the slot 10, so that the grounding plate 33 does not protrude in the slot 10, so that the first grounding terminal 31 and the second grounding terminal 32 can be stably positioned, and at the same time, the grounding plate 33 will not affect the insertion of the mating connector into the slot 10.

[0046] The first grounding terminal 31 and the second grounding terminal 32 are mirror-symmetrical structures and are symmetrically distributed on both sides of the grounding plate 33 .

[0047] The first pin portion 312 is fixed with a first solder ball 317, and the second pin portion 322 is fixed with a second solder ball 327. By pre-positioning the first solder ball 317 and the second solder ball 327 on the first pin portion 312 and the second solder ball 327, it is possible to facilitate the rapid assembly of the entire high-speed connector and the PCB board in the later stage, thereby improving efficiency.

[0048] The first grounding terminal 31 and the second grounding terminal 32 are both made of C7025 copper alloy, which is a copper alloy containing 2% nickel and 0.5% silicon. C7025 copper alloy has high strength, high thermal conductivity and excellent corrosion resistance; it has excellent thermal properties, and the following are some characteristics of its thermal properties: High thermal conductivity: C7025 copper alloy has extremely high thermal conductivity, which enables it to conduct heat quickly. It is an excellent thermal conductive material and can be widely used in heat exchangers, heat conductors and other fields. Moderate thermal expansion coefficient: The thermal expansion coefficient of C7025 copper alloy is relatively low, so that it can maintain a relatively stable size and shape when the temperature changes, which makes it very suitable for application in high temperature environments. Good high temperature resistance: C7025 copper alloy has good high temperature resistance and can work for a long time in high temperature environment without plastic deformation or softening, which makes it widely used in high temperature working environments such as aerospace and automobiles. Strong oxidation resistance: C7025 copper alloy exhibits strong oxidation resistance in high temperature environment and is not easily corroded by oxides. This property makes it an ideal material for working in high temperature oxidation environment, such as burners, stoves, etc.

[0049] The grounding plate 33 is made of C7521 nickel silver, which is a copper-based alloy with nickel as the main added element. It is silvery white and has a metallic luster, hence the name nickel silver. Copper and nickel can be infinitely dissolved in each other to form a continuous solid solution, that is, no matter how much the proportion of each other is, it is always an α-single-phase alloy. When nickel is melted into red copper and the content exceeds 16%, the color of the resulting alloy becomes as white as silver. The higher the nickel content, the whiter the color. The nickel content in nickel silver is generally 25%. Pure copper plus nickel can significantly improve strength, corrosion resistance, hardness, resistance and thermoelectricity, and reduce the temperature coefficient of resistivity. Therefore, nickel silver has abnormally good mechanical and physical properties compared to other copper alloys, good ductility, high hardness, beautiful color, corrosion resistance, and rich deep drawing performance. It is widely used in shipbuilding, petrochemical, electrical appliances, instruments, medical equipment, daily necessities, handicrafts and other fields, and is also an important resistor and thermocouple alloy.

[0050] The grounding terminal of the utility model adopts a grounding sheet 33 made of C7521 white copper to connect the first grounding terminal 31 and the second grounding terminal 32 made of C7025 copper alloy on both sides, which can greatly improve the crosstalk resonance.

[0051] As shown in the combined figure, it is a characteristic impedance curve diagram of the high-speed connector using a one-touch grounding terminal in the prior art; as shown in the combined figure, it is a characteristic impedance curve diagram of the improved grounding terminal of the utility model. It can be seen from the two curve diagrams that the characteristic impedance of the improved grounding terminal of the utility model is better than the characteristic impedance of the high-speed connector using a one-touch grounding terminal in the prior art. The improvement of the grounding terminal ensures impedance matching and the impedance has been optimized.

[0052] As shown in the combined figure, it is a summation curve diagram of the near-end crosstalk of the high-speed connector using a one-touch grounding terminal in the prior art, as shown in the combined figure, it is a summation curve diagram of the far-end crosstalk of the high-speed connector using a one-touch grounding terminal in the prior art, as shown in the combined figure, it is a summation curve diagram of the near-end crosstalk after the grounding terminal is improved by the utility model, as shown in the combined figure, it is a summation curve diagram of the far-end crosstalk after the grounding terminal is improved by the utility model. It can be seen from the four curve diagrams that after the grounding terminal is improved by the utility model, the crosstalk resonance has been greatly improved, and the overall result is good.

[0053] In summary, the utility model divides a grounding terminal 3 into three independent, smaller parts, specifically the first grounding terminal 31, the second grounding terminal 32 and the grounding plate 33. During assembly, the first grounding terminal 31 and the second grounding terminal 32 are first inserted into the same second terminal slot 12, and finally the grounding plate 33 is also inserted and fixed in the second terminal slot 12, and embedded between the first grounding terminal 31 and the second grounding terminal 32, and the first grounding terminal 31 and the second grounding terminal 32 are respectively driven to move outward to hold and position with the inner wall of the second terminal slot 12, so as to ensure that the first grounding terminal 31 and the second grounding terminal 32 are stably installed in the insulating seat 1, and are extremely firm. During the insertion and use process, there will be no phenomenon of the grounding terminal retreating, thereby ensuring the quality of the product. At the same time, the grounding terminal 3 will not scratch the inner wall of the second terminal slot 12 during the assembly process, that is, it will not cause plastic debris or burrs to form on the inner wall of the second terminal slot 12, and there is no need to add additional steps for processing, thereby improving production efficiency and ensuring product quality.
