Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0022] An embodiment of the present invention provides a terminal structure 1000 of a high-speed connector.

[0023] See also Figures 1 to 5 In one embodiment of the present application, the terminal structure 1000 of the high-speed connector includes a first terminal assembly 200 and a second terminal assembly 300 that are pluggable and matched with each other; the first terminal assembly 200 includes a first insulating housing 210 and a first conductive terminal 220 with elasticity; the second terminal assembly 300 includes a second insulating housing 310 and a second conductive terminal 320 with elasticity; The first insulating housing 210 includes a plug tongue 211 and an outer housing 212 connected to each other, the plug tongue 211 is located inside the outer housing 212, a gap 230 is formed between the plug tongue 211 and the outer housing 212, and the first conductive terminal 220 is fixed to the plug tongue 211 and can be deformed in a direction away from the gap 230; The second insulating housing 310 is formed with a groove 330, and the second conductive terminal 320 is fixed to the inner wall of the groove 330, protrudes from the inner wall of the groove 330, and can be deformed in a direction away from the groove; After the second insulating housing 310 is received in the gap 230 and the inserting tongue 211 is received in the groove 330 , the first conductive terminal 220 contacts the second conductive terminal 320 .

[0024] It can be understood that the technical solution of the present application is to set a plug tongue 211, an outer shell 212 and a second insulating shell 310, and a gap 230 is formed between the plug tongue 211 and the outer shell 212, and the second insulating shell 310 is formed with a groove 330, the first conductive terminal 220 is fixed to the plug tongue 211, and can be deformed in a direction away from the gap 230; the second conductive terminal 320 is fixed to the inner wall of the groove 330, protrudes from the inner wall of the groove 330, and can be deformed in a direction away from the groove, so the technical solution of the present application is to set a first conductive terminal 220 with elasticity and a second conductive terminal 320 with elasticity; when the first terminal assembly 200 is plugged into the first terminal assembly 200, the first conductive terminal 220 is in contact with the second conductive terminal 320, and since both conductive terminals have a certain elasticity, the technical solution improves the reliability of the electrical connection of the connector. Furthermore, the gap 230 in the technical solution of the present application can accommodate the second insulating shell 310, and the groove 330 can be accommodated in the plug tongue 211, so the inner and outer surfaces of the second insulating shell 310 in the technical solution of the present application can be respectively locked with the surface of the plug tongue 211 and the inner wall of the outer shell 212 through friction, and the plug-in and unplugging of the connector of the present application is more reliable than the plug-in and plug-in socket in the prior art. Therefore, the connector of the technical solution of the present application improves the reliability of the high-speed connector terminal structure and the plug-in and unplugging connection of the connector.

[0025] It can be understood that the terminal structure of the technical solution of the present invention can be used for connecting between circuit boards, and can also be used for connecting between wires and circuit boards, or between wires.

[0026] See also Figure 3 and Figure 4 In a specific embodiment, the first conductive terminal 220 is formed with a first rod portion 221 and a second rod portion 222 which are set at an obtuse angle; the plug-in tongue 211 is formed with a first limiting surface 211a for limiting the movable range of the first rod portion 221 and a first guide surface 211b for guiding the movement of the second rod portion 222.

[0027] For further information, please refer to Figure 3 The second conductive terminal 320 is formed with a third rod portion 321 and a fourth rod portion 322 which are arranged at an obtuse angle; the second insulating shell 310 is formed with a second limiting surface 310a for limiting the deformation range of the third rod portion 321 and a second guide surface 310b for guiding the movement of the fourth rod portion 322.

[0028] It can be understood that when the first terminal assembly 200 is disconnected from the second terminal assembly 300 , the first rod portion 221 does not contact the first limiting surface 211 a , and the third rod portion 321 does not contact the second limiting surface 310 a .

[0029] When the first terminal assembly 200 is connected to the second terminal assembly 300, the first rod portion 221 is deformed toward the first limiting surface 211a, and the second rod portion 222 slides relative to the first guide surface 211b; the third rod portion 321 is deformed toward the second limiting surface 310a, and the fourth rod portion 322 slides relative to the second guide surface 310b.

[0030] For further information, see Figure 1 , Figure 2 and Figure 3 The second insulating housing 310 is further formed with a through hole 311, the through hole 311 is connected to the groove 330 through the second conductive terminal 320, and the number of the through holes 311 is the same as the number of the second conductive terminals 320. It can be understood that the through hole 311 is mainly provided to adjust the deformation of the second conductive terminal 320. Specifically, the user can adjust the deformation of the second conductive terminal 320 one by one or in batches by using other tools.

[0031] It can also be understood that the provision of the through hole 311 can be used for ventilation and heat dissipation, thereby avoiding signal loss or connector damage caused by overheating of the connector.

[0032] For further information, see Figure 2 and Figure 3 In one embodiment of the present application, the outer shell 212 of the first insulating shell 210 is formed with air holes 212a corresponding to the positions of the through holes 311, and the air holes 212a are used for heat dissipation.

[0033] It is understandable that when the first terminal assembly 200 is plugged into the second terminal assembly 300 , the position of the air hole 212 a can be connected to the through hole 311 , thereby achieving natural heat dissipation of the first conductive terminal 220 and the second conductive terminal 320 .

[0034] It can also be understood that the provision of the air hole 212a can also be used to adjust the reliability of the contact between the first conductive terminal 220 and the second conductive terminal 320 when the first terminal assembly 200 and the second terminal assembly 300 are plugged into each other.

[0035] See also Figure 1 , Figure 2 as well as Figures 5 to 10The present invention also proposes a connector including a terminal structure 1000 of any of the above-mentioned high-speed connectors, which includes a locking structure 400, and the locking structure 400 includes a locking component 410 arranged on the outer shell 212 and a matching piece arranged on the outer wall of the second insulating shell 310; the locking component 410 and the matching piece can be relatively fixed.

[0036] It can be understood that the provision of the locking structure 400 in the technical solution of the present application can make the connection between the first terminal assembly 200 and the second terminal assembly 300 more reliable.

[0037] Optionally, the locking component 410 is a rocker clip, the matching piece is a limiting protrusion, and pressing the halved clip can cause the rocker clip to detach from the limiting protrusion.

[0038] Optionally, the locking component 410 may also be a silicone gasket, and the matching piece may be a limiting protrusion, and the limiting protrusion may cause the silicone gasket to deform so as to relatively fix the connector.

[0039] Optionally, the locking assembly 410 is a snap-fit ​​component.

[0040] See also Figures 5 to 8 In a specific embodiment of the present application, the locking assembly 410 includes a guide rail 411 and a locking member 412 that cooperates with the guide rail 411. The locking member 412 passes through the outer shell 212, and a push stop member 413 is provided outside the outer shell 212. A rolling member 414 is formed at one end of the locking member 412 away from the push stop member 413, and the rolling member 414 is interference fit with the mating member.

[0041] Specifically, Figure 5 , Figure 6 and Figure 7 The number of the rolling members 414 is two, and the matching members are convex strips arranged at intervals; the two rolling members 414 can be locked with the convex strips after pushing and pulling the push-stop member 413.

[0042] For specific locking status, please refer to Figure 6 The working state of pushing and pulling the push stop member 413 can be referred to Figure 7 And because there is inevitably a gap between the second insulating housing 310 and the outer housing 212, the locking member 412 can move relative to the matching member under the action of an external force.

[0043] Please continue reading Figure 8 , Fig. 9 and Fig.10The locking assembly 410 also includes a guide column 416 arranged parallel to the guide rail 411, and the guide column 416 is fixedly connected to the outer shell 212. A first spring 417 and a second spring 418 are sleeved on the guide column 416. The first spring 417 and the second spring 418 are respectively arranged on both sides of the locking member 412 and fixedly connected to the locking member 412.

[0044] It is understandable that a first spring 417 and a second spring 418 are provided on both sides of the locking member 412 , and when the locking member 412 moves along the guide rail 411 , the first spring 417 and the second spring 418 help to keep the locking member at a preset position.

[0045] Specifically, the rolling element 414 is in an elongated strip shape, and in order to increase the friction force with the second insulating shell 310 , the outer surface of the rolling element 414 has a plurality of protrusion structures.

[0046] Optionally, the protrusion structure may be a strip-shaped protrusion with a sawtooth-shaped cross section, or a strip-shaped protrusion with a fan-shaped cross section.

[0047] It should also be emphasized that the connector including the terminal structure 1000 of any of the above-mentioned high-speed connectors, when including the locking assembly 410, is mainly used for connecting wires to wires, or wires to circuit boards.

[0048] Optionally, in order for the rolling element 414 itself to have a certain deformation capability, the rolling element 414 may be made of rubber.

[0049] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
