Summary of the Invention

[0003] The purpose of the present invention is to provide a high-speed connector adopting a terminal structure, aiming to design a termination method to improve the connection reliability of the high-speed connector.

[0006] The first insulating housing includes an insertion tongue and an outer housing that are connected to each other. The insertion tongue is located inside the outer housing, and a gap is formed between the insertion tongue and the outer housing. The first conductive terminal is fixed to the insertion tongue and can deform in a direction away from the gap;

[0007] The second insulating housing is formed with a groove, and the second conductive terminal is fixed to the inner wall of the groove, protruding from the inner wall of the groove and can deform in a direction away from the groove;

[0008] After the second insulating housing is received in the gap and the insertion tongue is received in the groove, the first conductive terminal contacts the second conductive terminal;

[0009] The high-speed connector includes a locking structure, and the locking structure includes a locking component provided on the outer housing and a cooperating component provided on the outer wall of the second insulating housing; the locking component and the cooperating component can be relatively fixed;

[0010] The locking assembly includes a guide rail and a locking member that cooperates with the guide rail. The locking member passes through the outer housing, and a pushing stop member is provided outside the outer housing. A rolling member is formed at one end of the locking member facing away from the pushing stop member, and the rolling member is in interference fit with the mating member.

[0011] In one embodiment, the first conductive terminal is formed with a first rod portion and a second rod portion arranged at an obtuse angle; the insertion tongue is formed with a first limiting surface for limiting the movement range of the first rod portion and a first guiding surface for guiding the movement of the second rod portion.

[0012] In one embodiment, the second conductive terminal is formed with a third rod portion and a fourth rod portion arranged at an obtuse angle; the second insulating housing is formed with a second limiting surface for limiting the deformation range of the third rod portion and a second guiding surface for guiding the movement of the fourth rod portion.

[0013] In one embodiment, the second insulating housing is further formed with through holes, and the through holes communicate with the grooves through the second conductive terminals. The number of the through holes is the same as the number of the second conductive terminals.

[0014] In one embodiment, the outer housing of the first insulating housing is formed with air holes corresponding to the positions of the through holes, and the air holes are used for heat dissipation.

[0015] In one embodiment, the number of the rolling members is two, and the mating members are convex strips arranged at intervals; the two rolling members can be locked with the convex strips after pushing and pulling the pushing stop member.

[0016] In one embodiment, the locking assembly further includes a guide post arranged parallel to the guide rail.

The second conductive terminal is fixed to the inner wall of the groove, protrudes from the inner wall of the groove, and can deform in a direction away from the groove. Therefore, in the technical solution of this application, the elastic first conductive terminal and the elastic second conductive terminal are provided. When the first terminal assembly is inserted and mated with the first terminal assembly, the first conductive terminal contacts the second conductive terminal. Since both conductive terminals have a certain elasticity, the reliability of the electrical connection of the connector is improved in this technical solution. Further, in the technical solution of this application, the gap can accommodate the second insulating housing, and the groove can be accommodated in the insertion tongue. Therefore, in the technical solution of this application, the inner and outer surfaces of the second insulating housing can be locked in friction with the surface of the insertion tongue and the inner wall of the outer housing respectively. Compared with the cooperation between the plug and the socket in the prior art, the plugging and unplugging cooperation of the connector in this application is more reliable. At the same time, the locking structure can make the connection between the first terminal assembly and the second terminal assembly more reliable. Therefore, the connector of the technical solution of this application improves the reliability of the terminal structure and the plugging and unplugging connection of the high-speed connector.

[0037] For the technical objectives, features, and advantages of the present invention to be more obvious and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings. These 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. Therefore, it should not be construed as a limitation to the present invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present.

[0039] The following further illustrates the technical solutions of the present invention with reference to the accompanying drawings and through specific embodiments.

[0040] The embodiments of the present invention provide a high-speed connector employing a terminal structure.

[0041] Please refer to Figures 1 to 5 , in an 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 inserted and mated with each other; the first terminal assembly 200 includes a first insulating housing 210 and a first conductive terminal 220 having elasticity; the second terminal assembly 300 includes a second insulating housing 310 and a second conductive terminal 320 having elasticity;

[0042] The first insulating housing 210 includes a plugging tongue 211 and an outer housing 212 that are connected to each other. The plugging tongue 211 is located inside the outer housing 212. A gap 230 is formed between the plugging tongue 211 and the outer housing 212. The first conductive terminal 220 is fixed to the plugging tongue 211 and can be deformed in a direction away from the gap 230;

[0043] The second insulating housing 310 is formed with a groove 330. 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;

[0044] The second insulating housing 310 is received in the gap 230. After the insertion tongue 211 is received in the groove 330, the first conductive terminal 220 contacts the second conductive terminal 320.

[0045] It can be understood that in the technical solution of the present application, by providing the insertion tongue 211, the outer housing 212 and the second insulating housing 310, a gap 230 is formed between the insertion tongue 211 and the outer housing 212. The second insulating housing 310 is formed with a groove 330. The first conductive terminal 220 is fixed to the insertion 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. Therefore, in the technical solution of the present application, by providing the elastic first conductive terminal 220 and the elastic second conductive terminal 320, when the first terminal assembly 200 is inserted and mated with the second terminal assembly 200, the first conductive terminal 220 contacts the second conductive terminal 320. Since both conductive terminals have a certain elasticity, the reliability of the electrical connection of the connector is improved. Further, in the technical solution of the present application, the gap 230 can receive the second insulating housing 310, and the groove 330 can receive the insertion tongue 211. Therefore, in the technical solution of the present application, the inner and outer surfaces of the second insulating housing 310 can be frictionally engaged and locked with the surface of the insertion tongue 211 and the inner wall of the outer housing 212 respectively. Compared with the cooperation between the plug and the socket in the prior art, the plugging and unplugging cooperation of the connector of the present application is more reliable. Therefore, the connector of the technical solution of the present application improves the reliability of the high-speed connector terminal structure and its plugging and unplugging connection.

[0046] It can be understood that the terminal structure of the technical solution of the present invention can be used for the connection between circuit boards, and can also be used for the connection between a wire and a circuit board, or between wires.

[0047] Please refer to 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 that are arranged at an obtuse angle. The insertion tongue 211 is formed with a first limiting surface 211a for restricting the movement range of the first rod portion 221 and a first guiding surface 211b for guiding the movement of the second rod portion 222.

[0048] Further, please continue to refer to Figure 3The 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 housing 310 is formed with a second limiting surface 310a for limiting the deformation range of the third rod portion 321 and a second guiding surface 310b for guiding the movement of the fourth rod portion 322.

[0049] It can be understood that when the first terminal assembly 200 is disconnected from the second terminal assembly 300, the first rod portion 221 is not in contact with the first limiting surface 211a, and the third rod portion 321 is not in contact with the second limiting surface 310a.

[0050] When the first terminal assembly 200 is connected to the second terminal assembly 300, the first rod portion 221 deforms in a direction close to the first limiting surface 211a, and the second rod portion 222 slides relative to the first guiding surface 211b; the third rod portion 321 deforms in a direction close to the second limiting surface 310a, and the fourth rod portion 322 slides relative to the second guiding surface 310b.

[0051] Further, please refer to Figure 1 、 Figure 2 and Figure 3 The second insulating housing 310 is further formed with through holes 311. The through holes 311 are communicated with the grooves 330 through the second conductive terminals 320, and the number of the through holes 311 is the same as that of the second conductive terminals 320. It can be understood that the through holes 311 are mainly provided to adjust the deformation of the second conductive terminals 320. Specifically, the user can use other tools to adjust the deformation of the second conductive terminals 320 one by one or in batches.

[0052] It can also be understood that the through holes 311 can be used for ventilation and heat dissipation, so as to avoid signal loss or connector damage caused by overheating of the connector.

[0053] Further, please refer to Figure 2 and Figure 3 In an embodiment of the present application, the outer housing 212 of the first insulating housing 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.

[0054] It can be understood that when the first terminal assembly 200 is inserted and mated with the second terminal assembly 300, the positions of the air holes 212a can be communicated with the through holes 311, so as to realize natural heat dissipation of the first conductive terminals 220 and the second conductive terminals 320.

[0055] It can also be understood that the arrangement of the air holes 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 is plugged and mated with the second terminal assembly 300.

[0056] Please refer to Figure 1 、 Figure 2 and Figures 5 to 10 In addition, the present invention also provides a connector including the terminal structure 1000 of any one of the above-mentioned high-speed connectors. The connector includes a locking structure 400, and the locking structure 400 includes a locking component 410 disposed on the outer casing 212 and a mating member disposed on the outer wall of the second insulating housing 310; the locking component 410 and the mating member can be relatively fixed.

[0057] It can be understood that in the technical solution of the present application, setting the locking structure 400 can make the connection between the first terminal assembly 200 and the second terminal assembly 300 more reliable.

[0058] Optionally, the locking component 410 is a toggle clip, and the mating member is a limiting protrusion. Pressing the half clip can make the toggle clip disengage from the limiting protrusion.

[0059] Optionally, the locking component 410 can also be a silicone gasket, and the mating member is a limiting protrusion. The limiting protrusion can cause the silicone gasket to deform, so that the connector is relatively fixed.

[0060] Optionally, the locking component 410 is a clamping member.

[0061] Please refer to Figures 5 to 8 In a specific embodiment of the present application, the locking component 410 includes a guide rail 411 and a locking member 412 that cooperates with the guide rail 411. The locking member 412 penetrates through the outer casing 212, and a stop member 413 is disposed outside the outer casing 212. A rolling member 414 is formed at one end of the locking member 412 facing away from the stop member 413, and the rolling member 414 is in interference fit with the mating member.

[0062] Specifically, as Figure 5 、 Figure 6 and Figure 7 the number of the rolling members 414 is two, and the mating member is a rib disposed at intervals; the two rolling members 414 can be locked with the rib after pushing and pulling the stop member 413.

[0063] Specifically, the locked state can be referred to Figure 6 and the operating state of pushing and pulling the stop member 413 can be referred to Figure 7Moreover, since there are inevitably gaps between the second insulating housing 310 and the outer housing 212, the locking member 412 can move relative to the mating member under the action of an external force.

[0064] Please continue to refer to Figure 8 , Figure 9 and Figure 10 , the locking assembly 410 further includes a guide post 416 arranged parallel to the guide rail 411. The guide post 416 is fixedly connected to the outer housing 212. A first spring 417 and a second spring 418 are sleeved on the guide post 416. The first spring 417 and the second spring 418 are respectively arranged on both sides of the locking member 412 and are fixedly connected to the locking member 412.

[0065] It can be understood that by arranging the first spring 417 and the second spring 418 on both sides of the locking member 412, 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 in a preset position.

[0066] Specifically, the rolling member 414 is strip-shaped, and in order to increase the friction with the second insulating housing 310, the outer surface of the rolling member 414 has a plurality of convex structures.

[0067] Optionally, the convex structure can be a strip-shaped convex with a serrated cross-section or a strip-shaped convex with a fan-shaped cross-section.

[0068] It should also be emphasized that for a connector including the terminal structure 1000 of the high-speed connector described in any one of the above, when it mainly includes the locking assembly 410 for connecting wires to wires or wires to a circuit board.

[0069] Optionally, in order to endow the rolling member 414 with a certain deformation ability, the rolling member 414 can be made of rubber material.

[0070] As mentioned above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
