[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on December 29, 2023, with application number 202311864096.1 and application name "A High-Speed ​​Connector", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the technical field of electronic equipment, and in particular to a high-speed connector, an electronic component, an electronic device, and a signal transmission method. Background Art

[0004] Electronic devices typically include multiple electronic components, which require signal transmission between them. With the continuous evolution of modern electronic devices, the number of transmitted signals is increasing, and the speeds are also getting faster. As a crucial component of signal transmission, high-speed connectors significantly impact the operating speed of electronic devices. Consequently, high-speed connectors also place high demands on their signal transmission speeds. Furthermore, in addition to signal transmission speeds, high-speed connectors also place increasing demands on crosstalk, latency, signal integrity, stability, and interference immunity. Summary of the Invention

[0005] The present application provides a high-speed connector, an electronic component, an electronic device and a signal transmission method. The high-speed connector has good signal transmission performance, which is beneficial to improving the performance of the electronic component and the electronic device.

[0006] In a first aspect, the present application provides a high-speed connector. The high-speed connector comprises a metal housing and multiple terminals, each terminal having a first terminal portion at one end facing the plug-in / unplug end of the high-speed connector. The metal housing includes a first housing, with the first terminal portion located within an inner cavity of the first housing. The first housing of the metal housing serves as a reference ground and shielding structure for the terminals. The cross-section of the first housing along a first plane is a rounded rectangular shape, with the first plane perpendicular to the plug-in / unplug direction of the high-speed connector. The first housing comprises four flat plates and four arc plates, with the arc plates serving only to provide transitional connections between adjacent flat plates. The flat plates of the first housing have a relatively large area. The first housing of the metal housing can be manufactured using a metal stamping process. The large area of ​​the flat plates of the first housing simplifies the process for manufacturing the flat plates. Furthermore, the metal housing can be formed directly from flat plates, which reduces the number of steps. Furthermore, the flat plates are less susceptible to internal stress, making the manufacturing tolerances of the flat plates easier to control, thereby improving the manufacturing accuracy of the first housing of the metal housing. Therefore, the metal housing in this solution is easier to manufacture to the theoretical design value with high precision, achieving landing of the metal housing with high accuracy. This can improve the signal transmission performance of high-speed connectors, for example, it can make the circuit impedance continuity of high-speed connectors good, crosstalk small, delay low, signal integrity high, stability high and strong anti-interference properties.

[0007] In a further technical solution, the high-speed connector further comprises an insulating block, which is assembled within the metal housing and includes one or more receiving holes, into which the multiple terminals are inserted. This insulating block can be manufactured using an injection molding process and is adapted to fit within the rounded rectangular first housing. Its structure is relatively simple and regular, which improves the precision of the insulating block and facilitates assembly. The portion of the insulating block within the first housing also has a roughly rounded rectangular cross-section along the first plane, which simplifies the transmission impedance design of the high-speed connector and improves the connector's performance in transmitting high-speed signals.

[0008] In a specific implementation of the insulating block, the outer surface of the insulating block facing the metal shell can include multiple raised structures, with the surface of the multiple raised structures facing the metal shell being in contact with the metal shell. Air columns are formed between adjacent raised structures. By adjusting the size, number, and position of the raised structures, the size, number, and position of the air columns can be simultaneously adjusted, facilitating precise design of the high-speed connector's dielectric constant, achieving impedance continuity, and further improving the connector's transmission performance.

[0009] In a specific technical solution, the protrusion structure is a strip-shaped protrusion extending along the plugging and unplugging direction of the high-speed connector, so that the insulating block structure is continuous along the plugging and unplugging direction of the high-speed connector, and impedance continuity can also be achieved along the plugging and unplugging direction of the high-speed connector.

[0010] In one technical solution, the insulating block includes a first portion and a second portion arranged sequentially in a direction away from the plug-in end. The first portion and the second portion are located within the inner cavity of the first housing, and the cross-sectional area of ​​the first portion along a first plane is smaller than the cross-sectional area of ​​the second portion along a second plane. The first portion can be inserted into the receiving slot of the opposite high-speed connector. When a gap exists between the high-speed connector and the opposite connector, a certain amount of dielectric (the first portion) exists in the plane where the gap exists, making the impedance of the high-speed connector more continuous, which is beneficial for improving signal transmission performance and providing greater disassembly compatibility.

[0011] When the above technical solution is specifically implemented, each circumferential side surface of the above-mentioned first part is a first inclined surface, and the first inclined surface can specifically be a continuous inclined surface, a stepped inclined surface, a plane, a curved surface or an arc surface, etc. The above-mentioned first inclined surface includes a first end and a second end arranged in sequence in a direction away from the plug-in end, and the distance between the first end and the surface of the adjacent metal shell is greater than the distance between the second end and the surface of the adjacent metal shell. In one technical solution, among the multiple cross-sections of the above-mentioned first part along the first plane, the closer to the second part, the larger the area of ​​the above-mentioned cross-section. The first inclined surface is inclined close to the surface of the metal shell in a direction away from the plug-in end. In addition to achieving impedance continuity, the first inclined surface in this embodiment can also serve as a guide surface to facilitate the plugging of the high-speed connector with the opposite connector.

[0012] To facilitate terminal assembly, the insulating block also includes a groove. This groove is located on the side of the receiving hole away from the plug-in end and is connected to the receiving hole. The terminal is assembled through the groove and inserted into the receiving hole along the plug-in and pull-out direction of the high-speed connector. The insulating block also includes a retaining post located on the sidewall of the groove and spaced a certain distance from the bottom of the groove. The retaining post and the bottom of the groove are used to position the terminal, reducing the probability of the terminal retreating and the risk of pin backing out.

[0013] In one technical solution, the terminal further includes a second terminal portion connected to the first terminal portion, and the first terminal portion and the second terminal portion form a certain angle. The first surface of the first terminal portion includes a protrusion, and the protrusion includes a second inclined surface. The second inclined surface includes a third end and a fourth end sequentially arranged in a direction away from the plug-in end, and the distance between the third end and the first surface is smaller than the distance between the fourth end and the first surface. The angle between the end surface of the protrusion facing away from the plug-in end and the second inclined surface is an acute angle. Specifically, the protrusion is a ratchet located on the first terminal portion as a barb structure. In the process of the first terminal portion moving relative to the insulating block in a direction away from the plug-in end, the friction between the protrusion and the inner wall of the accommodating hole is relatively large, which is conducive to increasing the difficulty of the terminal withdrawing from the insulating block and reducing the risk of pin withdrawal.

[0014] In one technical solution, the edge of the surface of the second terminal portion facing the plug-in end has a guide surface to facilitate the second terminal portion to pass over the above-mentioned limit post. The surface of the second terminal portion facing away from the plug-in end is flat, which facilitates the reliable engagement of the surface of the second terminal portion facing away from the plug-in end with the limit post.

[0015] The above-mentioned metal shell also includes a second shell, which is connected to the first shell. Specifically, the above-mentioned second shell is located on the side of the first shell away from the plug-in end, and the second terminal part is located in the inner cavity of the second shell. The above-mentioned second metal shell can serve as a reference ground and shielding structure for the second terminal part. The above-mentioned second shell is detachably equipped with a metal plate, which is located on the side of the second terminal part away from the plug-in end. The metal plate shields the signal from the side of the second terminal part away from the plug-in end. The second shell and the metal plate can also shield the interference of the terminal, thereby improving the signal transmission performance of the high-speed connector.

[0016] In a further technical solution, the high-speed connector further includes a protective sleeve. The protective sleeve is sleeved on the outside of the first shell and fixedly assembled with the metal shell. The protective sleeve may specifically be an insulating protective sleeve for protecting the first shell. The protective sleeve includes at least one guide groove facing the inner side of the first shell, and the guide groove extends along the plug-in and pull-out direction of the high-speed connector. On the one hand, the guide groove can serve as a guiding structure to facilitate the connection between the high-speed connector and the opposite connector. On the other hand, it can also serve as an anti-mock structure by making the number or position of guide grooves of different models of connectors different, thereby preventing high-speed connectors of different functions and models from being inserted incorrectly.

[0017] The protective cover specifically includes a first side panel, a second side panel, a third side panel and a card plate. The first side panel and the second side panel are arranged opposite to each other, and the third side panel and the card plate are arranged opposite to each other. Wherein: the distance between the card plate and the third side panel is greater than the distance between the end of the first side panel away from the third side panel and the third side panel, and the card plate and the first side panel are connected by a first arc plate. The distance between the card plate and the third side panel is greater than the distance between the end of the second side panel away from the third side panel and the third side panel, and the card plate and the second side panel are connected by a second arc plate. The first arc plate, the card plate and the second arc plate are enclosed to form a bayonet. The two ends of the card plate are connected to the side panels at both ends by arc plates, which improves the force form of the card plate and is conducive to enhancing the structural strength of the protective cover.

[0018] In order to enhance the strength of the bayonet of the protective cover, reinforcement parts such as reinforcing ribs or reinforcing blocks can be added to the first curved plate and the second curved plate, so that the structural strength of the position where the first curved plate and the second curved plate are located is stronger, and the connection strength between the clamping plate and the first side plate and the second side plate is stronger and not easily damaged.

[0019] The high-speed connector further comprises a stop pin, the protective sleeve comprises a through hole, and the metal shell comprises a slot. The stop pin is passed through the through hole and engaged with the slot, thereby achieving fixed assembly of the protective sleeve and the metal shell, and the assembly method is relatively simple.

[0020] In order to improve connection reliability, the surface of the above-mentioned stop pin includes a first bulge and a second bulge. The first bulge abuts against the inner wall of the through hole of the protective cover, and the second bulge abuts against the side wall of the slot of the metal shell. The area of ​​the orthographic projection of the second bulge on the surface of the stop pin is larger than the area of ​​the orthographic projection of the first bulge on the surface of the stop pin. Due to the different deformation amounts of the surface of the metal shell and the surface of the insulating block, the area of ​​the second bulge is larger than the area of ​​the first bulge, and the contact area between the second bulge and the surface of the metal shell is larger than the contact area between the first bulge and the insulating block, so that the stop pin is more reliably fixed in the above-mentioned through hole and slot, thereby improving the reliability of the fixed assembly of the protective cover and the metal shell.

[0021] In a second aspect, the present application further provides an electronic assembly. The electronic assembly includes an electronic device and the high-speed connector provided in the first aspect, wherein the electronic device is electrically connected to terminals of the high-speed connector. The high-speed connector of the electronic assembly has good signal transmission performance, thereby improving the performance of the electronic assembly.

[0022] In a third aspect, the present application further provides an electronic device. The electronic device includes a counterpart connector and the electronic assembly provided in the second aspect, wherein the counterpart connector is plugged into a high-speed connector. The high-speed connector has good signal transmission performance, and the electronic device also has good performance.

[0023] In a fourth aspect, the present application further provides a signal transmission method. This signal transmission method utilizes the high-speed connector provided in the first aspect to transmit signals. The terminals of the high-speed connector include power terminals and communication terminals. The signal transmission method specifically comprises: transmitting a power signal via the power terminals; and transmitting a communication signal via the communication terminals. Signal transmission using the high-speed connector provides high signal quality and a fast signal transmission rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] References in this specification to "one embodiment" or "a specific embodiment" mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. The terms "including," "comprising," "having," and their variations all mean "including but not limited to," unless otherwise specifically stated.

[0048] To facilitate understanding of the high-speed connector, electronic component, electronic device, and signal transmission method provided in the embodiments of the present application, the application scenarios thereof are first introduced below.

[0049] The electronic devices in the embodiments of this application can be communication devices (such as routers), computing devices (such as servers), network devices (such as switches), storage devices (such as storage arrays), and vehicles (for example, vehicles including onboard devices such as sensors), and in particular, electronic devices that require high-speed signal transmission. This application does not limit the specific type of electronic device; any electronic device that uses a high-speed connector to achieve signal transmission can adopt the technical solutions provided in this application.

[0050] For ease of description, this solution uses a vehicle as an example application scenario. Application scenarios involving other types of electronic devices are not discussed in detail here. With the advent of the connected vehicle era and the widespread adoption of intelligent driving, more data needs to be collected and processed at faster speeds. For example, signals from sensors such as cameras, radar, and lidar inside and outside the vehicle must be transmitted; other tasks include transmitting signals between vehicle sensors, between vehicles and network devices, and between vehicles and infrastructure. This requires the generation, transmission, reception, storage, and processing of massive amounts of data. Vehicles are filled with electronic chips and board-level systems that communicate via high-speed networks and buses. Because high-speed connectors are crucial components in the signal transmission path, customizing and selecting high-performance high-speed connectors is a critical component of vehicle development, whether for entertainment or autonomous driving.

[0051] With the continuous advancement of intelligent connected vehicles, the continuous improvement of in-vehicle infotainment functions, the continuous installation of high-computing autonomous driving computing platforms and a large number of on-board sensors, and the increasing demand for information transmission rates and other performance of high-speed connectors, the transmission of high-speed data signals not only requires good circuit impedance continuity, low crosstalk, low latency, and high signal integrity, but also requires high stability, anti-interference, and high temperature resistance. To achieve the above-mentioned performance of high-speed connectors, in addition to optimizing the design of the high-speed connector structure, it is also necessary to consider the tolerances in the high-speed connector manufacturing process and whether the design solution can be implemented more accurately and reliably.

[0052] The structure equipped with a high-speed connector in the above-mentioned electronic device is an electronic assembly, which can specifically be a circuit board assembly or a module assembly. For example, the above-mentioned electronic assembly can include an electronic device and a high-speed connector, and the high-speed connector includes terminals, and the above-mentioned electronic device is electrically connected to the terminals of the high-speed connector. In an optional embodiment, the terminals of the above-mentioned electronic device and the high-speed connector are electrically connected through a circuit board, and the electronic assembly is formed into a single-board structure. Specifically, the electronic device and the high-speed connector can be respectively fixed to the circuit board, the electronic device is connected to the circuit board, and the high-speed connector is also connected to the circuit board, thereby realizing the connection between the electronic device and the high-speed connector. In an optional embodiment, the above-mentioned electronic device and the high-speed connector can also be electrically connected using an electrical transmission component. For example, the connecting line can be a lead, a flexible circuit board or a cable.

[0053] The electronic device also includes a counterpart connector. The high-speed connector is plugged into the counterpart connector to achieve signal transmission between the electronic component with the high-speed connector and the electronic component with the counterpart connector.

[0054] The high-speed connector provided in the present application is used to transmit high-speed signals, for example, a signal transmission rate greater than or equal to 10 Gps; in addition, the high-speed connector can also be used to transmit high-frequency signals.

[0055] FIG1 is a schematic diagram of the structure of a high-speed connector in an embodiment of the present application, and FIG2 is a schematic diagram of an exploded structure of a high-speed connector in an embodiment of the present application. As shown in FIG1 and FIG2 , in one embodiment, the high-speed connector 100 of the present application includes a metal shell 1, an insulating block 2, and a plurality of terminals 4. In a specific embodiment, the number of terminals 4 included in the high-speed connector 100 may be one, two, or more. In a possible embodiment, the number of terminals 4 included in the high-speed connector 100 is an even number, and every two terminals 4 are used to transmit a pair of differential signals. The plurality of terminals 4 are fixedly assembled with the insulating block 2, and the insulating block 2 is fixedly assembled with the metal shell 1 to form the high-speed connector 100.

[0056] Continuing with reference to Figures 1 and 2, the connector of the present application may further include a protective sleeve 3, with the metal housing 1 fixedly assembled with the protective sleeve 3. The protective sleeve 3 can protect the metal housing 1 and can be provided with a snap-fit ​​structure, etc., for connecting with a counterpart connector, thereby improving the reliability of the connection between the connector and the counterpart connector in the embodiment of the present application.

[0057] FIG3 is a schematic diagram of a cross-sectional structure of a connector in an embodiment of the present application. As shown in FIG3 , in the embodiment of the present application, one end of each terminal 4 facing the plug-in end 00 of the high-speed connector 100 is a first terminal portion 41. The metal shell 1 includes a first shell 11, and the first terminal portion 41 is located in the inner cavity of the first shell 11. The above-mentioned first shell 11 can serve as a reference ground and shielding structure for the terminal 4. FIG4 is a schematic diagram of the cross-sectional structure of the first shell 11 in an embodiment of the present application. Please refer to FIG4 . The cross-sectional shape of the first shell 11 along the first plane is a rounded rectangle. The above-mentioned first plane is specifically perpendicular to the plug-in direction M of the high-speed connector 100. The cross-sectional shape of the first shell 11 along the first plane specifically includes four straight edges, including a first straight edge 111, a second straight edge 112, a third straight edge 113, and a fourth straight edge 114 arranged in sequence along the circumferential direction. The first straight edge 111 and the third straight edge 113 are of equal length and parallel to each other, and the second straight edge 112 and the fourth straight edge 114 are of equal length and parallel to each other. Furthermore, the first straight edge 111 and the second straight edge 112 are perpendicular to each other. Furthermore, the orthographic projection of the first straight edge 111 on the third straight edge 113 coincides with the third straight edge 113, and the orthographic projection of the second straight edge 112 on the fourth straight edge 114 coincides with the fourth straight edge 114. A circular arc edge 115 connects any two adjacent straight edges, creating a rounded transition between the two adjacent straight edges.

[0058] From the perspective of the three-dimensional structure of the metal shell 1, the first shell 11 forms an accommodating cavity, which extends along the plug-in direction M of the high-speed connector 100, and the first terminal portion 41 is located in the above-mentioned accommodating cavity. The above-mentioned accommodating cavity includes four side panels and four arc panels. The above-mentioned side panels are flat panels. The four side panels and the four arc panels are arranged in sequence along the axial direction to enclose the above-mentioned accommodating cavity. The above-mentioned four side panels include a fourth side panel, a fifth side panel, a sixth side panel and a seventh side panel arranged in sequence along the axial direction, wherein the fourth side panel is parallel to the sixth side panel, the fifth side panel is parallel to the seventh side panel, and the fourth side panel is perpendicular to the fifth side panel. Adjacent side panels are connected by arc panels.

[0059] When preparing the first housing, a metal stamping process can be used to produce the first housing 11 of the metal housing 1. In this embodiment, the flat plate of the first housing 11 has a larger area, making the process for producing the flat plate relatively simple. Furthermore, the metal housing 1 can be formed directly from a flat plate, which reduces the number of steps. Furthermore, the flat plate is less susceptible to internal stress, making the production tolerances of the flat plate easier to control, thereby improving the production accuracy of the first housing 11 of the metal housing 1. Therefore, the metal housing 1 in this embodiment is easier to produce to the theoretical design value with greater precision, allowing the metal housing 1 to be placed on the ground with higher precision. This can improve the signal transmission performance of the high-speed connector 100, for example, by ensuring that the circuit impedance continuity, crosstalk, latency, signal integrity, stability, and anti-interference properties of the high-speed connector 100 are improved. Specifically, FIG5 is a comparison chart comparing the performance of the high-speed connector in the embodiment of the present application with that of the prior art connector. As shown in FIG5 , the solid line in the figure represents the performance of the prior art connector, while the dashed line represents the performance of the high-speed connector 100 in the embodiment of the present application. It can be seen that the performance of the high-speed connector 100 in the embodiment of the present application is superior to that of the prior art connector.

[0060] Figure 6 is a schematic structural diagram of an insulating block 2 in an embodiment of the present application, and Figure 7 is a schematic structural diagram of an end face of the insulating block 2 and the first housing 11 in an embodiment of the present application, specifically a schematic structural diagram of the end faces of the insulating block 2 and the first housing 11 facing the plug-in end 00. Referring to Figures 2, 3, 6, and 7, in one embodiment, the insulating block 2 is assembled to the metal housing 1, and the insulating block 2 includes one or more receiving holes 21, into which the multiple terminals 4 of the high-speed connector 100 are inserted. Specifically, in one embodiment, the number of receiving holes 21 in the insulating block 2 can be the same as the number of terminals 4 in the high-speed connector 100, with each receiving hole 21 corresponding to each terminal 4, and one terminal 4 being inserted into one receiving hole 21. In one embodiment, the number of receiving holes 21 in the insulating block 2 can also be less than the number of terminals 4 in the high-speed connector 100, with two or more terminals 4 being arranged in one receiving hole 21. In another embodiment, the insulating block 2 can also include one receiving hole 21, into which all terminals 4 are inserted. In specific implementations, the relationship between the receiving hole 21 and the terminal 4 is not limited to the aforementioned embodiments, and can be designed based on other requirements. The insulating block 2 can be manufactured using an injection molding process and adapted to fit within the rounded rectangular first housing 11. Its relatively simple and regular structure improves the precision of the insulating block 2 and facilitates assembly. The portion of the insulating block 2 within the first housing 11 also has a roughly rounded rectangular cross-section along the first plane, simplifying the transmission impedance design of the high-speed connector 100 and improving the high-speed signal transmission performance of the high-speed connector 100.

[0061] Referring to Figures 6 and 7 , the outer surface of the metal shell 1 includes a plurality of raised structures 22. Specifically, the raised structures 22 extend along the insertion and removal direction M of the high-speed connector 100. The surfaces of the raised structures 22 facing the metal shell 1 are in contact with the metal shell 1. Air columns are formed between adjacent raised structures 22. By adjusting the size, number, and position of the raised structures 22, the size, number, and position of the air columns can be simultaneously adjusted, thereby facilitating the precise design of the dielectric constant of the high-speed connector 100, achieving impedance continuity, and further improving the transmission performance of the high-speed connector 100.

[0062] In a specific embodiment, the insulating block 2 has a symmetrical structure. Specifically, the insulating block 2 is symmetrical about a first axis of symmetry 23 extending along the first direction, about a second axis of symmetry 24 extending along the second direction, and about the center point O of the rounded rectangle. This solution ensures impedance symmetry around the signal side, which is beneficial for improving signal transmission performance. In a specific embodiment, the first axis of symmetry 23 and the second axis of symmetry 24 are perpendicular.

[0063] FIG8 is a schematic diagram of the side structure of the insulating block 2 and the first housing 11 according to an embodiment of the present application. Referring again to FIG6 and FIG8 , the insulating block 2 includes a first portion 25 and a second portion 26 arranged sequentially in a direction away from the plug-in end 00. The first portion 25 and the second portion 26 are located in the inner cavity of the first housing 11. The cross-sectional area of ​​the first portion 25 along the first plane is smaller than the cross-sectional area of ​​the second portion 26 along the second plane.

[0064] FIG9 is a schematic diagram of a structure in which a high-speed connector and a counterpart connector are plugged in according to an embodiment of the present application. As shown in FIG9 , in order to adapt to the insulating block 2, the insulating structure of the counterpart connector 200 can include a receiving groove adapted to the above-mentioned first part 25. When the counterpart connector 200 is plugged in with the high-speed connector 100 in the present application, the above-mentioned first part 25 is accommodated in the receiving groove of the counterpart connector 200. Then, when a gap appears between the high-speed connector 100 and the counterpart connector 200, the gap is not a continuous gap. FIG10 is a schematic diagram of a structure in which a connector and a counterpart connector are plugged in according to the prior art. As shown in FIG10 , in the prior art, when a gap appears between the high-speed connector 100 and the counterpart connector 200, the gap is a planar gap, and a cavity appears at the gap, resulting in discontinuous impedance. As shown in FIG9 , the present application can avoid the occurrence of the above-mentioned voids. Even if a gap appears between the high-speed connector 100 and the opposite connector 200, there is a certain dielectric in the plane where the gap is located, so that the impedance of the high-speed connector 100 is relatively continuous, which is beneficial to improving the signal transmission performance, and the high-speed connector 100 can have greater demodulation compatibility.

[0065] As shown in Figure 8 , in one embodiment, the first portion 25 of the insulating block 2 can be a plane parallel to the insertion and removal direction M. For example, the cross-section of the first portion 25 along the first plane can also be a rounded rectangle or a rectangle. This helps simplify the structure of the high-speed connector 100 and improve the manufacturing accuracy of the insulating block 2, thereby enhancing the impedance control capability of the high-speed connector 100 and improving signal transmission performance.

[0066] FIG11 is a schematic diagram of the side structure of the insulating block 2 and first housing 11 in an embodiment of the present application. As shown in FIG6 and FIG11 , each circumferential side surface of the first portion 25 of the insulating block 2 comprises a first inclined surface 251. The first inclined surface 251 includes a first end 2511 and a second end 2512 arranged in sequence in a direction away from the plug-in end 00. The distance between the first end 2511 and the surface of the adjacent metal housing 1 is greater than the distance between the second end 2512 and the surface of the adjacent metal housing 1. Alternatively, in a cross-section of the first portion 25 along the first plane, the closer the cross-section is to the second portion 26, the larger the cross-section area. Alternatively, the smaller the distance between the cross-section and the second portion 26, the larger the cross-section area. The first inclined surface 251 is inclined toward the surface of the metal housing 1 in a direction away from the plug-in end 00. In addition to achieving impedance continuity, the first inclined surface 251 in this embodiment also serves as a guide surface to facilitate mating of the high-speed connector 100 with the mating connector 200.

[0067] In one embodiment, the first inclined surface 251 is a continuous inclined surface. In another embodiment, the first inclined surface 251 may be a stepped inclined surface, which is not specifically limited in this application. In addition, in alternative embodiments, the first inclined surface 251 may be a flat surface, a curved surface, or an arcuate surface, which is not specifically limited in this application.

[0068] FIG12 is a partial cross-sectional view of the insulating block 2 and the terminal 4 in an embodiment of the present application. As shown in FIG12 , in one embodiment, the insulating block 2 includes a groove 27, which is located on the side of the receiving hole 21 away from the plug-in end 00, and the groove 27 is connected to the receiving hole 21. Specifically, the notch of the groove 27 is located on the side away from the plug-in end 00, and the bottom 271 of the groove 27 is connected to the receiving hole 21. FIG13 is a structural schematic diagram of the terminal in an embodiment of the present application. As shown in FIG13 , the terminal 4 includes a first terminal portion 41 and a second terminal portion 42. The second terminal portion 42 is connected to the side of the first terminal portion 41 away from the plug-in end 00, and the first terminal portion 41 and the second terminal portion 42 form a certain angle. When assembling the terminal 4, the terminal 4 is inserted into the insulating block 2 from the notch of the groove 27 in the direction toward the plug-in end 00, and the first terminal portion 41 is inserted into the receiving hole 21 of the insulating block 2. The insulating block 2 includes a limiting post 28 located on the sidewall of the groove 27 and spaced a certain distance from the bottom 271 of the groove 27. The limiting post 28 and the bottom 271 of the groove 27 are used to limit the terminal 4, reducing the probability of the terminal retreating and the risk of pin withdrawal.

[0069] In a specific embodiment, the above-mentioned certain angle can be a 90° angle, which is conducive to improving the fit between the terminal 4 and the groove bottom 271 of the insulating block 2, and the first terminal portion 41 and the second terminal portion 42 have less overlap in the projection relationship, which is conducive to reducing signal crosstalk and improving the performance and speed of signal transmission of the high-speed connector 100.

[0070] Referring to Figures 12 and 13 , the edge of the surface of the second terminal portion 42 facing the plug-in end 00 has a guide surface 421, which facilitates the second terminal portion 42 passing over the retaining post 28. The surface of the second terminal portion 42 facing away from the plug-in end 00 is flat, facilitating reliable engagement between the surface of the second terminal portion 42 facing away from the plug-in end 00 and the retaining post 28. In a specific embodiment, the retaining post 28 and the bottom 271 of the groove 27 are spaced a distance equal to the thickness of the second terminal portion 42 along the plug-in direction M, thereby improving the reliability of the terminal 4 within the insulating block 2. In a specific embodiment, the insulating block 2 itself has a certain flexibility, which can also make the above-mentioned limiting column 28 have a certain flexibility. In short, when the second terminal part 42 is inserted into the groove 27, the insulating block 2 and / or the limiting column 28 are deformed, so that the thickness of the groove 27 increases and the second terminal part 42 can pass through the position where the limiting column 28 is located; after the second terminal part 42 passes through the position where the limiting column 28 is located, the insulating block 2 and / or the limiting column 28 restore their shape, and the second terminal part 42 can be clamped to the side of the limiting column 28 facing the plug-in end 00, so that the second terminal part 42 is more reliably limited to the insulating block 2.

[0071] Continuing to refer to Figures 12 and 13, to improve the connection reliability between the terminal 4 and the insulating block 2, the first surface of the first terminal portion 41 can include a protrusion 411. This protrusion 411 includes a second inclined surface 4111. The second inclined surface 4111 includes a third end 41111 and a fourth end 41112 arranged in sequence in a direction away from the plug end 00. The distance between the third end 41111 and the first surface is smaller than the distance between the fourth end 41112 and the first surface. During the insertion of the first terminal portion 41 into the receiving hole 21, the second inclined surface 4111 provides a certain guiding effect, which minimizes the obstruction to the insertion process of the first terminal portion 41. The angle between the end face of the protrusion 411 facing away from the plug-in end 00 and the second inclined surface 4111 is an acute angle, so that the protrusion 411 is a barbed structure. When the first terminal portion 41 moves relative to the insulating block 2 in a direction away from the plug-in end 00, the friction between the protrusion 411 and the inner wall of the accommodating hole 21 is relatively large, which is conducive to increasing the difficulty of the terminal 4 withdrawing from the insulating block 2 and reducing the risk of pin withdrawal.

[0072] In a specific embodiment, the end surface of the protrusion 411 facing away from the plug end 00 is a serrated structure, which is beneficial to further improve the friction between the protrusion 411 and the inner wall of the receiving hole 21 of the insulating block 2.

[0073] In an optional embodiment, the protrusion 411 may be provided on one surface of the first terminal portion 41, or on two or more surfaces of the first terminal portion 41. For example, in the embodiments shown in Figures 12 and 13, two opposing surfaces of the first terminal portion 41 each have a protrusion structure 22.

[0074] In an optional embodiment, the number of raised structures 22 provided on a surface of the first terminal portion 41 is not limited. Only one raised structure 22 may be provided, or two or more raised structures 22 may be provided according to actual needs to enhance the friction between the first terminal portion 41 and the insulating block 2, thereby enhancing the reliability of the first terminal portion 41 being fixed in the receiving hole 21.

[0075] Continuing to refer to Figures 2 and 3, the metal housing 1 in this application also includes a second housing 12, which is connected to the first housing 11 and is located on the side of the first housing 11 facing away from the plug-in end 00. The second terminal portion 42 is located in the inner cavity of the second housing 12. Specifically, the second housing 12 and the first housing 11 can be integrally molded. Alternatively, the first housing 11 and the second housing 12 can be prepared separately and then connected using a connection process such as welding.

[0076] Continuing with Figure 3, the second housing 12 has an opening opposite the insulating block 2. The insulating block 2 extends through this opening into the metal housing 1, and a portion of the insulating block 2 extends into the first housing 11. A metal plate 121 is removably mounted on the second housing 12. This metal plate 121 is located on the side of the second terminal portion 42 facing away from the plug end 00. This second housing 12 and metal plate 121 also shield the terminals 4 from interference, improving the signal transmission performance of the high-speed connector 100.

[0077] There are many options for realizing the detachable assembly of the metal plate 121 and the second housing 12, which are not limited in this application. For example, the metal plate 121 can be fixed to the second housing 12 using screws; or the metal plate 121 can be snap-fitted to the second housing 12.

[0078] Figure 14 is a schematic diagram of the back structure of a high-speed connector in an embodiment of the present application, Figure 15 is a schematic diagram of a structure in which the metal plate 121 is removed in an embodiment of the present application, and Figure 16 is a schematic diagram of a structure of the metal plate 121 in an embodiment of the present application. As shown in Figures 14, 15 and 16, the second shell 12 can include a slot 122, and the metal plate 121 is inserted into the above-mentioned slot 122. As shown in Figure 16, the surface of the above-mentioned metal plate 121 also includes one or more protrusions 1211, and the protrusions 1211 are located on the side surface of the metal plate 121 facing the insulating block 2, and the protrusions 1211 abut against the insulating block 2. This solution can make the friction between the metal plate 121 and the insulating block 2 larger, improve the assembly reliability of the metal plate 121, and not easily fall off from the slot 122, thereby improving the shielding reliability of the high-speed connector 100.

[0079] As shown in Figure 16, in an optional embodiment, the protrusion 1211 is a circular protrusion. When the metal plate 121 includes a plurality of protrusions 1211, the plurality of protrusions 1211 are sequentially spaced along a straight line.

[0080] The corners of the metal plate 121 may also be notched, and accordingly, the second housing 12 also has a protrusion adapted to the notched corner. The notched corner and the protrusion serve as foolproof structures for the metal plate 121, so that the protrusion can be arranged toward the insulation.

[0081] FIG17 is a schematic diagram of the structure of the protective cover 3 in the embodiment of the present application. As shown in FIG2, FIG3 and FIG17, the protective cover 3 in the embodiment of the present application can be an insulating protective cover, which is arranged on the outside of the first shell 11 and fixedly assembled with the metal shell 1. FIG18 is a schematic diagram of the front structure of the protective cover 3 in the embodiment of the present application. As shown in FIG17 and FIG18, the protective cover 3 includes at least one guide groove 31 facing the inner side of the first shell 11. The guide groove 31 extends along the plug-in direction M of the high-speed connector 100. The guide groove 31 can serve as a guide structure for plugging the opposite connector with the connector in this embodiment, facilitating smoother plug-in of the two high-speed connectors 100. In this solution, the number and position of the guide grooves 31 of different types of high-speed connectors can be different, so that the guide groove 31 can also serve as an anti-mock structure to prevent high-speed connectors of different functions and models from being plugged in incorrectly.

[0082] Figure 19 is a schematic diagram of different settings of the guide grooves of the protective cover in an embodiment of the present application. As shown in Figure 19, by adjusting the number and position of the guide grooves, different types of high-speed connectors can be easily distinguished and mis-insertion is less likely to occur.

[0083] Furthermore, as shown in Figures 17 and 18, the protective cover 3 includes a first side panel 32, a second side panel 33, a third side panel 34, and a retaining plate 35. The first side panel 32 and the second side panel 33 are disposed opposite each other, while the third side panel 34 and the retaining plate 35 are disposed opposite each other. The distance between the retaining plate 35 and the third side panel 34 is greater than the distance between the end of the first side panel 32 distal from the third side panel 34 and the third side panel 34. The retaining plate 35 is connected to the first side panel 32 via a first curved plate 36. The distance between the retaining plate 35 and the third side panel 34 is greater than the distance between the end of the second side panel 33 distal from the third side panel 34 and the third side panel 34. The retaining plate 35 is connected to the second side panel 33 via a second curved plate 37. Assuming that the four sides of the protective cover 3 are generally planar, the retaining plate 35 can be considered an arched retaining plate 35, protruding from the plane of the side surface of the protective cover 3. Specifically, the first curved plate 36, the retaining plate 35, and the second curved plate 37 enclose a retaining plate. Both ends of the clamping plate 35 are connected to the side plates at both ends through arc-shaped plates, which improves the stress form of the clamping plate 35 and is beneficial to enhancing the structural strength of the protective cover 3 .

[0084] In order to enhance the strength of the bayonet of the protective cover 3, reinforcement parts such as reinforcing ribs or reinforcing blocks can be added to the first curved plate and the second curved plate, so that the structural strength of the position where the first curved plate and the second curved plate are located is stronger, and the connection strength between the clamping plate 35 and the first side plate 32 and the second side plate 33 is stronger and not easily damaged.

[0085] As shown in Figures 2, 3, and 17, in one embodiment, to achieve secure assembly between the protective sleeve 3 and the metal housing 1, the protective sleeve 3 includes a through hole 38, and the metal housing 1 includes a retaining slot 13. The high-speed connector 100 includes a retaining pin 5, which passes through the through hole 38 and engages with the retaining slot 13. This ensures secure assembly between the protective sleeve 3 and the metal housing 1.

[0086] FIG20 is a schematic diagram of the structure of the stop pin 5 in an embodiment of the present application. Referring to FIG20 , the surface of the stop pin 5 also includes a convex bump, which abuts against the through hole 38 or the retaining groove 13 of the protective cover 3 to improve the reliability of the stop pin 5 being fixed within the through hole 38 and the retaining groove 13. Specifically, the convex bump can be a circular convex bump, thereby simplifying the preparation process of the stop pin 5.

[0087] In a specific embodiment, the bulge on the surface of the stop pin 5 specifically includes a first bulge 51 and a second bulge 52. The first bulge 51 abuts against the inner wall of the through hole 38 of the protective cover 3, and the second bulge 52 abuts against the side wall of the slot 13 of the metal shell 1. The area of ​​the orthographic projection of the second bulge 52 on the surface of the stop pin 5 is larger than the area of ​​the orthographic projection of the first bulge 51 on the surface of the stop pin 5. Since the deformation amounts of the surface of the metal shell 1 and the surface of the insulating block 2 are different, the area of ​​the second bulge 52 is larger than the area of ​​the first bulge 51, and the contact area between the stop pin 5 and the surface of the metal shell 1 is larger than the contact area between the stop pin 5 and the insulating block 2, so that the stop pin 5 is more reliably fixed to the metal shell 1 and the insulating block 2, respectively, thereby improving the reliability of the fixed assembly of the protective cover 3 and the metal shell 1.

Specifically, the terminals of the high-speed connector include power terminals and communication terminals. The signal transmission method specifically includes: transmitting a power signal via the power terminals; and transmitting a communication signal via the communication terminals.

[0089] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
