Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and particularly to a high-speed connector, an electronic component, an electronic device, and a signal transmission method. Background Art

[0002] An electronic device usually includes multiple electronic components, and signal transmission is required between the multiple electronic components. With the continuous evolution of current electronic devices, the number of transmitted signals is increasing, and the rate is also getting faster. As an important part in signal transmission, a high-speed connector also has an important impact on the operating rate of an electronic device. Therefore, higher requirements are also put forward for the signal transmission rate of the high-speed connector. In addition, in addition to the signal transmission rate, higher and higher requirements are also put forward for the crosstalk, delay, signal integrity, stability, and anti-interference of the signals transmitted by the high-speed connector. Summary of the Invention

[0003] This application provides a high-speed connector, an electronic component, an electronic device, and a signal transmission method. The signal transmission performance of the high-speed connector is good, which is beneficial to improving the performance of the electronic component and the electronic device.

[0004] In a first aspect, this application provides a high-speed connector. The high-speed connector includes a metal housing and a plurality of terminals. One end of each terminal facing the insertion and extraction end of the high-speed connector is a first terminal portion. The metal housing includes a first housing, and the first terminal portion is located in the inner cavity of the first housing. The first housing of the above metal housing serves as the reference ground and shielding structure of the terminal. The cross-sectional shape of the first housing along a first plane is a rounded rectangle, and the first plane is perpendicular to the insertion and extraction direction of the high-speed connector. The first housing includes four flat plates and four arc plates, and the arc plates are only used to realize the transition connection between two adjacent flat plates. The area of the flat plates of the first housing is relatively large. The first housing of the above metal housing can be prepared by a metal stamping process. The area of the flat plate of the first housing is large, and the process of preparing the flat plate is relatively simple. In addition, the metal housing can be directly formed by processing the flat plate, with fewer processes. Moreover, the flat plate is not prone to internal stress, and the preparation tolerance of the flat plate is relatively easy to control, which is beneficial to improving the preparation accuracy of the first housing of the metal housing. Therefore, the metal housing in this solution is relatively easy to accurately prepare the designed theoretical value and realize the implementation of the metal housing with high precision. Thereby, the signal transmission performance of the high-speed connector can be improved. For example, the circuit impedance continuity of the high-speed connector can be good, the crosstalk can be small, the delay can be low, the signal integrity can be high, the stability can be high, and the anti-interference ability can be strong, etc.

[0005] In a further technical solution, the above high-speed connector further includes an insulating block, which is assembled on the metal housing, and the insulating block includes one or more receiving holes, and a plurality of terminals are inserted into the one or more receiving holes. The insulating block can be prepared by an injection molding process and is adapted to the first housing with a rounded rectangle shape. The structure is relatively simple and regular, which is beneficial to improving the precision of the insulating block and is relatively convenient for assembly. The cross-sectional shape of the part of the insulating block in the first housing along the first plane is also approximately a rounded rectangle, which is beneficial to simplifying the transmission impedance design of the high-speed connector and improving the performance of the high-speed connector in transmitting high-speed signals.

[0006] When specifically implementing the above insulating block, the outer peripheral surface of the insulating block facing the metal housing may include a plurality of protruding structures, and the surfaces of the plurality of protruding structures facing the metal housing are in contact with the metal housing. The space between adjacent protruding structures is equivalent to an air column. By adjusting the size, quantity, and position of the above protruding structures, the size, quantity, and position of the air column can be synchronously set, so as to accurately design the dielectric constant of the high-speed connector, achieve impedance continuity, and further improve the transmission performance of the high-speed connector.

[0007] In a specific technical solution, the above protruding structure is a strip-shaped protrusion extending along the insertion and extraction direction of the high-speed connector, so that the structure of the insulating block is continuous along the insertion and extraction direction of the high-speed connector, and impedance continuity can also be achieved along the insertion and extraction direction of the high-speed connector.

[0008] In a technical solution, the above insulating block includes a first part and a second part arranged in sequence along the direction away from the insertion and extraction end. The cross-sectional area of the first part along the first plane in the inner cavity of the first housing is smaller than the cross-sectional area of the second part along the second plane. The above first part can be used to insert into the receiving groove of the mating high-speed connector. When there is a gap between the high-speed connector and the mating connector, there is also a certain medium (the above first part) in the plane where the gap is located, so that the impedance of the high-speed connector is relatively continuous, which is beneficial to improving the signal transmission performance, and the high-speed connector can have greater demating compatibility.

[0009] When specifically implementing the above technical solution, each peripheral side surface of the above 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 first inclined surface includes a first end and a second end arranged in sequence along the direction away from the insertion and extraction end, and the distance between the first end and the surface of the adjacent metal housing is greater than the distance between the second end and the surface of the adjacent metal housing. In a technical solution, among the multiple cross-sections of the above first part along the first plane, the closer the cross-section is to the second part, the larger the area of the cross-section. The first inclined surface is inclined towards the surface of the metal housing along the direction away from the insertion and extraction end. In this embodiment, in addition to achieving impedance continuity, the first inclined surface can also be used as a guiding surface to facilitate the insertion of the high-speed connector and the mating connector.

[0010] To facilitate the assembly of the terminals, the above-mentioned insulating block further includes a groove. The groove is located on the side of the receiving hole away from the plugging and unplugging end, and the groove communicates with the receiving hole. The terminal is assembled from the above-mentioned groove and inserted into the above-mentioned receiving hole along the plugging and unplugging direction of the high-speed connector. The above-mentioned insulating block includes a limiting post, and the limiting post is located on the side wall of the groove and is spaced a certain distance from the bottom of the groove. The above-mentioned limiting post and the bottom of the groove are used to limit the terminal, which can reduce the probability of the terminal retreating and reduce the risk of pin withdrawal.

[0011] In a technical solution, the above-mentioned 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 above-mentioned first terminal portion includes a protruding portion, and the protruding portion includes a second inclined surface. The second inclined surface includes a third end and a fourth end arranged in sequence along the direction away from the plugging and unplugging end. The distance between the third end and the first surface is less than the distance between the fourth end and the first surface. The included angle between the end face of the protruding portion facing away from the plugging and unplugging end and the second inclined surface is an acute angle. Specifically, the above-mentioned protruding portion is a barb structure and is a ratchet tooth located on the first terminal portion. During the movement of the first terminal portion relative to the insulating block along the direction away from the plugging and unplugging end, the frictional force between the protruding portion and the inner wall of the receiving hole is relatively large, which is beneficial to increasing the difficulty of the terminal withdrawing from the insulating block and reducing the risk of pin withdrawal.

[0012] In a technical solution, the edge of the surface of the above-mentioned second terminal portion facing the plugging and unplugging end has a guiding surface, which is convenient for the second terminal portion to cross the above-mentioned limiting post. The surface of the second terminal portion facing away from the plugging and unplugging end is a flat surface, which is convenient for the surface of the second terminal portion facing away from the plugging and unplugging end to be reliably clamped with the limiting post.

[0013] The above-mentioned metal housing further includes a second housing, and the second housing is connected to the first housing. Specifically, the above-mentioned second housing is located on the side of the first housing away from the plugging and unplugging end, and the second terminal portion is located in the inner cavity of the second housing. The above-mentioned second metal housing can be used as the reference ground and shielding structure of the second terminal portion. The second housing is detachably assembled with a metal plate, and the metal plate is located on the side of the second terminal portion away from the plugging and unplugging end. The metal plate shields the signal from the side of the second terminal portion away from the plugging and unplugging end. The second housing and the metal plate can also shield the interference of the terminal, improving the signal transmission performance of the high-speed connector.

[0014] In a further technical solution, the above high-speed connector further includes a protective sleeve. The protective sleeve is sleeved on the outside of the first housing and is fixedly assembled with the metal housing. The protective sleeve may specifically be an insulating protective sleeve for protecting the first housing. The inner side of the protective sleeve facing the first housing includes at least one guiding groove, and the guiding groove extends along the plugging and unplugging direction of the high-speed connector. On the one hand, the guiding groove can serve as a guiding structure to facilitate the connection between the high-speed connector and the mating connector. On the other hand, it can also be used as an anti-misinsertion structure by making the number or position of the guiding grooves of different models of connectors different, preventing misinsertion of high-speed connectors with different functions and models.

[0015] Specifically, the protective sleeve includes a first side plate, a second side plate, a third side plate, and a clamping plate. The first side plate and the second side plate are arranged opposite to each other, and the third side plate and the clamping plate are arranged opposite to each other. Among them: the distance between the clamping plate and the third side plate is greater than the distance between the end of the first side plate away from the third side plate and the third side plate, and the clamping plate and the first side plate are connected by a first arc-shaped plate. The distance between the clamping plate and the third side plate is greater than the distance between the end of the second side plate away from the third side plate and the third side plate, and the clamping plate and the second side plate are connected by a second arc-shaped plate. The above first arc-shaped plate, clamping plate, and second arc-shaped plate enclose to form a bayonet. The two ends of the clamping plate are connected to the side plates at both ends through arc-shaped plates, which improves the stress form of the clamping plate and is beneficial to enhancing the structural strength of the protective sleeve.

[0016] In order to enhance the strength of the bayonet of the protective sleeve, strengthening parts such as reinforcing ribs or reinforcing blocks can also be added to the first arc-shaped plate and the second arc-shaped plate, so that the structural strength at the positions where the first arc-shaped plate and the second arc-shaped plate are located is relatively strong, and the connection strength between the clamping plate and the first side plate and the second side plate is relatively strong and not easily damaged.

[0017] The above high-speed connector further includes a stop pin. The protective sleeve includes a through hole, and the metal housing includes a clamping groove. The stop pin passes through the through hole and is clamped in the clamping groove, thereby realizing the fixed assembly of the protective sleeve and the metal housing, and the assembly method is relatively simple.

[0018] In order to improve the connection reliability, the surface of the above stop pin includes a first convex bump and a second convex bump. The first convex bump abuts against the inner wall of the through hole of the protective sleeve, and the second convex bump abuts against the side wall of the clamping groove of the metal housing. The area of the positive projection of the second convex bump on the surface of the stop pin is greater than the area of the positive projection of the first convex bump on the surface of the stop pin. Due to the different deformation amounts of the surface of the metal housing and the surface of the insulating block, the area of the second convex bump is greater than that of the first convex bump, and the contact area between the second convex bump and the surface of the metal housing is greater than the contact area between the first convex bump and the insulating block, making the stop pin more reliably fixed in the above through hole and clamping groove, thereby improving the reliability of the fixed assembly of the protective sleeve and the metal housing.

[0019] Second aspect, the present application further provides an electronic component. The electronic component includes an electronic device and the high-speed connector provided in the first aspect above, and the electronic device is electrically connected to the terminals of the high-speed connector. The high-speed connector of the electronic component has good signal transmission performance, and the performance of the electronic component is good.

[0020] Third aspect, the present application further provides an electronic device. The electronic device includes a mating connector and the electronic component provided in the second aspect above, and the mating connector is plugged into the high-speed connector. The high-speed connector has good signal transmission performance, and the performance of the electronic device is also good.

[0021] Fourth aspect, the present application further provides a signal transmission method. The signal transmission method uses the high-speed connector provided in the first aspect above to transmit signals. The terminals of the high-speed connector include a power terminal and a communication terminal, and the signal transmission method specifically includes: transmitting a power signal through the power terminal; transmitting a communication signal through the communication terminal.

[0068] In order to make the objectives, technical solutions, and advantages of this application clearer, the following will further describe this application in detail with reference to the accompanying drawings.

[0069] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0070] Reference to "an embodiment" or "a specific embodiment" etc. described in this specification means that a specific feature, structure or characteristic described in connection with that embodiment is included in one or more embodiments of the present application. The terms "comprising", "including", "having" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0071] To facilitate the understanding of the high-speed connector, electronic component, electronic device and signal transmission method provided by the embodiments of the present application, the application scenarios thereof will be introduced first below.

[0072] The electronic device in the embodiments of the present application can be an electronic device such as a communication device (such as a router), a computing device (such as a server), a network device (such as a switch), a storage device (such as a storage array) and a vehicle (for example, a vehicle including in-vehicle devices such as sensors), etc., especially an electronic device with high-speed signal transmission requirements. The present application does not limit the specific type of the electronic device, and any electronic device that uses a high-speed connector to achieve signal transmission can adopt the technical solution provided by the present application.

[0073] For the convenience of description, the application scenario of this solution is described by taking the electronic device as a vehicle as an example, and the application scenarios of other types of electronic devices are not described in detail here. With the advent of the era of the Internet of Vehicles and the popularization of intelligent driving, more data needs to be collected and processed at a faster speed. For example, transmitting signals of sensors such as in-vehicle and out-of-vehicle cameras, radars and lidars; or realizing signal transmission between vehicle sensors, between a vehicle and a network device, and between a vehicle and an infrastructure, etc., which requires generating, sending, receiving, storing and processing a large amount of data. Vehicles are full of electronic chips and board-level systems that communicate through high-speed networks and buses. Since the high-speed connector is an important structure on the signal transmission path, therefore, whether for entertainment or autonomous driving, customizing or selecting a high-performance high-speed connector is the top priority in the development of vehicles.

[0074] With the continuous advancement of current automotive intelligent networking, in-vehicle infotainment functions have been continuously improved. The successive installation of high-computing-power autonomous driving computing platforms and a large number of in-vehicle sensors has also put forward higher requirements for the information transmission rate and other performance of high-speed connectors. Transmitting high-speed data signals not only requires good circuit impedance continuity, low crosstalk, low delay, and high signal integrity, but also needs to have properties such as high stability, anti-interference, and high temperature resistance. In order to achieve the above performance of high-speed connectors, in addition to optimizing the design of the structure of high-speed connectors, it is also necessary to consider the size of tolerances during the preparation process of high-speed connectors, and whether the design scheme can be implemented accurately and reliably, etc.

[0075] The structure of the electronic device equipped with a high-speed connector in the above is an electronic component, and this electronic component can specifically be a circuit board component or a module component, etc. For example, the above electronic component can include electronic devices and high-speed connectors, and the high-speed connector includes terminals, and the above electronic devices are electrically connected to the terminals of the high-speed connector. In an alternative embodiment, the above electronic devices and the terminals of the high-speed connector are electrically connected through a circuit board, and the electronic component is formed into a single-board structure. Specifically, the electronic devices and the high-speed connectors can be respectively fixed to the circuit board, the electronic devices are connected to the lines of the circuit board, and the high-speed connectors are also connected to the lines of the circuit board, thereby realizing the connection between the electronic devices and the high-speed connectors. In an alternative embodiment, the above electronic devices and the high-speed connectors can also be electrically connected using an electrical transmission member. For example, the connection line can be a lead wire, a flexible circuit board, or a cable, etc.

[0076] The electronic device further includes a mating connector, and the above high-speed connector is plugged into the mating connector, thereby realizing signal transmission between the electronic component with the high-speed connector and the electronic component with the mating connector.

[0077] The high-speed connector provided in this application is used to transmit high-speed signals. For example, the transmission rate of the signal is greater than or equal to 10 Gbps; in addition, this high-speed connector can also be used to transmit high-frequency signals.

[0078] Figure 1 This is a schematic structural diagram of a high-speed connector in an embodiment of this application. Figure 2 This is an exploded structural diagram of a high-speed connector in an embodiment of this application, as Figure 1 and Figure 2As shown, in one embodiment, the high-speed connector 100 of the present application includes a metal housing 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 can be one, two, or more. In a possible embodiment, the number of terminals 4 included in the above high-speed connector 100 is an even number, and every two terminals 4 are used to transmit a pair of differential signals. The above plurality of terminals 4 are fixedly assembled with the insulating block 2, and the insulating block 2 is fixedly assembled with the metal housing 1 to form the high-speed connector 100.

[0079] Please continue to refer to Figure 1 and Figure 2 , the connector in the present application may further include a protective sleeve 3, and the metal housing 1 is fixedly assembled with the protective sleeve 3. The protective sleeve 3 can protect the metal housing 1 and can be provided with a latching structure or the like for connecting with the mating connector, improving the connection reliability between the connector in the embodiment of the present application and the mating connector.

[0080] Figure 3 is a schematic cross-sectional structure diagram of the connector in the embodiment of the present application. As Figure 3 shown, in the embodiment of the present application, one end of each terminal 4 facing the insertion / removal end 00 of the high-speed connector 100 is a first terminal portion 41. The metal housing 1 includes a first housing 11, and the first terminal portion 41 is located in the inner cavity of the first housing 11. The above first housing 11 can serve as a reference ground and a shielding structure for the terminal 4. Figure 4 is a schematic cross-sectional structure diagram of the first housing 11 in the embodiment of the present application. Please refer to Figure 4 , the cross-sectional shape of the first housing 11 along the first plane is a rounded rectangle, and the above first plane is specifically perpendicular to the insertion / removal direction M of the high-speed connector 100. The cross-sectional shape of the above first housing 11 along the first plane specifically includes a plurality of four straight edges. The four straight edges include 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 above first straight edge 111 and the third straight edge 113 have the same length and are parallel to each other. The second straight edge 112 and the fourth straight edge 114 have the same length and are parallel to each other. In addition, the above first straight edge 111 and the second straight edge 112 are perpendicular to each other. In addition, the orthographic projection of the above 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. An arc edge 115 is connected between any two adjacent straight edges, so that the adjacent two straight edges are in a rounded transition.

[0081] From the perspective of the three-dimensional structure of the metal housing 1, the first housing 11 encloses a receiving cavity that extends along the insertion and extraction direction M of the high-speed connector 100, and the first terminal portion 41 is located within the above-mentioned receiving cavity. The above-mentioned receiving cavity includes four side plates and four arc plates. The above-mentioned side plates are flat plates, and the four side plates and the four arc plates are arranged at intervals along the axial direction in sequence to enclose the above-mentioned receiving cavity. The above-mentioned four side plates include a fourth side plate, a fifth side plate, a sixth side plate, and a seventh side plate arranged in sequence along the axial direction. Among them, the fourth side plate is parallel to the sixth side plate, the fifth side plate and the seventh side plate are parallel, and the fourth side plate and the fifth side plate are perpendicular to each other. Adjacent side plates are connected by arc plates.

[0082] When specifically implementing the preparation of the above-mentioned first housing, the first housing 11 of the metal housing 1 can be prepared by a metal stamping process. In this solution, the area of the flat plate of the first housing 11 is relatively large, and the process for preparing the flat plate is relatively simple. In addition, the metal housing 1 can be directly formed by processing a flat plate, with fewer processes. Moreover, there are less likely to be internal stresses in the flat plate, and the preparation tolerance of the flat plate is relatively easy to control, which is beneficial to improving the preparation accuracy of the first housing 11 of the metal housing 1. Therefore, it is relatively easy to prepare the metal housing 1 in this solution to complete the designed theoretical value with relatively high precision and achieve the implementation of the metal housing 1 with high precision. Thereby, the signal transmission performance of the high-speed connector 100 can be improved. For example, it can make the circuit impedance of the high-speed connector 100 have good continuity, low crosstalk, low time delay, high signal integrity, high stability, and strong anti-interference ability, etc. Specifically, Figure 5 This is a comparison chart of the performance of the high-speed connector in the embodiment of the present application and the performance of the connector in the prior art. As Figure 5 shown, the solid line in the figure represents the performance of the connector in the prior art, and 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 the performance of the connector in the prior art.

Figure 7 This is a schematic end face structure diagram of the insulating block 2 and the first housing 11 in the embodiment of the present application, specifically the end face structure diagram of the insulating block 2 and the first housing 11 facing the insertion and extraction end 00. Please refer to Figure 2 、 Figure 3 、 Figure 6 and Figure 7, In one embodiment, the above-mentioned insulating block 2 is assembled to the metal housing 1, and the insulating block 2 includes one or more receiving holes 21, and a plurality of terminals 4 of the high-speed connector 100 are inserted into the one or more receiving holes 21. Specifically, in one embodiment, the number of the receiving holes 21 of the insulating block 2 can be made the same as the number of the terminals 4 of the high-speed connector 100, the above-mentioned receiving holes 21 correspond to the terminals 4 one by one, and one terminal 4 is inserted into one receiving hole 21. In one embodiment, the number of the receiving holes 21 of the insulating block 2 can also be made less than the number of the terminals 4 of the high-speed connector 100, and two or more terminals 4 are arranged in one receiving hole 21. In one embodiment, the insulating block 2 can also be made to include one receiving hole 21, and all the terminals 4 are inserted into the one receiving hole 21. In specific implementation, it is not limited to the above-listed several embodiments, and the relationship between the receiving holes 21 and the terminals 4 can be designed according to other requirements. The insulating block 2 can be prepared by an injection molding process and is adapted to the first housing 11 with a rounded rectangle shape. The structure is relatively simple and regular, which is beneficial to improving the accuracy of the insulating block 2 and is relatively convenient for assembly. The cross-sectional shape of the part of the insulating block 2 in the first housing 11 along the first plane is also approximately a rounded rectangle, which is beneficial to simplifying the transmission impedance design of the high-speed connector 100 and improving the performance of the high-speed connector 100 in transmitting high-speed signals.

[0084] Please refer to Figure 6 and Figure 7 , The outer peripheral surface of the metal housing 1 includes a plurality of protruding structures 22. Specifically, the above-mentioned protruding structures 22 extend along the insertion and extraction direction M of the high-speed connector 100. The surfaces of the above-mentioned plurality of protruding structures 22 facing the metal housing 1 are attached to the metal housing 1. The space between adjacent protruding structures 22 is equivalent to an air column. By adjusting the size, number and position of the above-mentioned protruding structures 22, the size, number and position of the air column can be set synchronously, so as to accurately design the dielectric constant of the high-speed connector 100, achieve impedance continuity, and further improve the transmission performance of the high-speed connector 100.

[0085] In a specific embodiment, the insulating block 2 is a symmetric structure. Specifically, the insulating block 2 is symmetric with respect to a first symmetry axis 23 extending in a first direction, symmetric with respect to a second symmetry axis 24 extending in a second direction, and centrosymmetric with respect to the center point O of the rounded rectangle. This solution makes the impedance on the peripheral side of the signal symmetric, which is beneficial to improving the transmission performance of the signal. In a specific embodiment, the above-mentioned first symmetry axis 23 and the second symmetry axis 24 are perpendicular to each other.

[0086] Figure 8 For a side structure schematic diagram of the insulating block 2 and the first housing 11 in the embodiment of the present application, please continue to refer to Figure 6 and Figure 8, the above-mentioned insulating block 2 includes a first part 25 and a second part 26 arranged in sequence along the direction away from the plug-in and unplugging end 00. The above-mentioned first part 25 and second part 26 are located in the inner cavity of the first housing 11, and the cross-sectional area of the first part 25 along the first plane is smaller than the cross-sectional area of the second part 26 along the second plane.

[0087] Figure 9 This is a schematic structural diagram of the high-speed connector and the mating connector plugged in the embodiment of the present application. As Figure 9 shown, in order to be adapted to the insulating block 2, the insulating structure of the mating connector 200 can include a receiving groove adapted to the above-mentioned first part 25. In the plugged state of the mating connector 200 and the high-speed connector 100 in the present application, the above-mentioned first part 25 is received in the receiving groove of the mating connector 200. Then when a gap appears between the high-speed connector 100 and the mating connector 200, the gap is not a continuous gap. Figure 10 This is a schematic structural diagram of the connector and the mating connector plugged in the prior art. As Figure 10 shown, in the prior art, when a gap appears between the high-speed connector 100 and the mating connector 200, the gap is a planar gap, and a cavity appears at the gap, resulting in impedance discontinuity. As Figure 9 shown, the present application can avoid the appearance of the above-mentioned cavity. Even if a gap appears between the high-speed connector 100 and the mating connector 200, there is a certain medium 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 Demating compatibility.

[0088] As Figure 8 shown, in one embodiment, the first part 25 of the above-mentioned insulating block 2 can be a plane parallel to the plugging and unplugging direction M. For example, the cross-section of the first part 25 along the first plane can also be a rounded rectangle or a rectangle. This is beneficial to simplifying the structure of the high-speed connector 100, improving the preparation accuracy of the insulating block 2, so as to improve the impedance control ability of the high-speed connector 100 and improve the signal transmission performance.

[0089] Figure 11 This is a schematic side structure diagram of the insulating block 2 and the first housing 11 in the embodiment of the present application. As Figure 6 and Figure 11As shown, each peripheral side surface of the first part 25 of the insulating block 2 is 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 shell 1 is greater than the distance between the second end 2512 and the surface of the adjacent metal shell 1. Alternatively, in the cross section of the first part 25 along the first plane, the closer to the second part 26, the larger the area of ​​the cross section is, or in other words, the smaller the distance between the cross section and the second part 26 is, the larger the area of ​​the cross section is. The first inclined surface 251 is inclined close to the surface of the metal shell 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 can also be used as a guide surface to facilitate the plugging of the high-speed connector 100 with the opposite connector 200.

[0090] In one embodiment, the first inclined surface 251 is a continuous inclined surface; in another embodiment, the first inclined surface 251 can also be a stepped inclined surface, which is not specifically limited in this application. In addition, in an optional embodiment, the first inclined surface 251 can be a plane, a curved surface, or an arc surface, which is not specifically limited in this application.

[0091] Figure 12 FIG. 1 is a partial cross-sectional view of the insulating block 2 and the terminal 4 in the embodiment of the present application. Figure 12 As shown, in one embodiment, the insulating block 2 includes a groove 27, which is located on a 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 a side away from the plug-in end 00, and the groove bottom 271 of the groove 27 is connected to the receiving hole 21. Figure 13 is a schematic diagram of a structure of a terminal in an embodiment of the present application, such as Figure 13 As shown, 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 column 28, which is located on the side wall of the groove 27 and is spaced a certain distance from the groove bottom 271 of the groove 27. The limiting column 28 and the groove bottom 271 of the groove 27 are used to limit the terminal 4, reduce the probability of the terminal retreating, and reduce the risk of pin withdrawal.

[0092] In a specific embodiment, the above-mentioned certain included angle can be a 90° included angle, which is beneficial to improving the fit between the terminal 4 and the bottom 271 of the groove 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 beneficial to reducing signal crosstalk and improving the performance and speed of the high-speed connector 100 in transmitting signals.

[0093] Please refer to Figure 12 and Figure 13 For the above, the edge of the surface of the second terminal portion 42 facing the insertion and extraction end 00 has a guiding surface 421, so as to facilitate the second terminal portion 42 to cross the above-mentioned limiting post 28. The surface of the second terminal portion 42 facing away from the insertion and extraction end 00 is a flat surface, which is convenient for the surface of the second terminal portion 42 facing away from the insertion and extraction end 00 to be reliably clamped with the limiting post 28. In a specific embodiment, the distance between the limiting post 28 and the bottom 271 of the groove 27 can be the thickness of the second terminal portion 42 in the insertion and extraction direction M, so as to improve the reliability of the terminal 4 in the insulating block 2. In a specific embodiment, the insulating block 2 itself has a certain flexibility, and the above-mentioned limiting post 28 can also have a certain flexibility. In short, when the second terminal portion 42 is inserted into the groove 27, the insulating block 2 and / or the limiting post 28 deform, so that the thickness of the groove 27 increases and the second terminal portion 42 can pass through the position where the limiting post 28 is located; after the second terminal portion 42 passes through the position where the limiting post 28 is located, the insulating block 2 and / or the limiting post 28 return to their original shapes, and the second terminal portion 42 can be clamped to the side of the limiting post 28 facing the insertion and extraction end 00, so that the second terminal portion 42 is more reliably limited in the insulating block 2.

[0094] Please continue to refer to Figure 12 and Figure 13 For the above, in order 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 protruding portion 411. The protruding portion 411 includes a second inclined surface 4111, and the second inclined surface 4111 includes a third end 41111 and a fourth end 41112 arranged in sequence along the direction away from the insertion and extraction end 00. The distance between the third end 41111 and the first surface is less than the distance between the fourth end 41112 and the first surface. During the process of inserting the first terminal portion 41 into the receiving hole 21, the above-mentioned second inclined surface 4111 has a certain guiding effect and less hindrance to the insertion process of the first terminal portion 41. The included angle between the end surface of the protruding portion 411 facing away from the insertion and extraction end 00 and the second inclined surface 4111 is an acute angle, so that the protruding portion 411 is a barbed structure. Then, during the process of the first terminal portion 41 moving relative to the insulating block 2 in the direction away from the insertion and extraction end 00, the friction between the protruding portion 411 and the inner wall of the receiving hole 21 is relatively large, which is beneficial to increasing the difficulty of the terminal 4 withdrawing from the insulating block 2 and reducing the risk of pin withdrawal.

[0095] In a specific embodiment, the end face of the protruding portion 411 facing away from the plug-in end 00 is a serrated structure, which is beneficial to further improve the friction between the protruding portion 411 and the inner wall of the receiving hole 21 of the insulating block 2.

[0096] In an alternative embodiment, one surface of the first terminal portion 41 may be provided with the protruding portion 411, and two or more surfaces of the first terminal portion 41 may also be provided with the protruding portion 411. For example, Figure 12 and Figure 13 in the illustrated embodiment, two opposite surfaces of the first terminal portion 41 each have a protruding structure 22.

[0097] In an alternative embodiment, the number of the protruding structures 22 provided on one surface of the first terminal portion 41 is not limited either. Only one protruding structure 22 may be provided, or two or more protruding structures 22 may be provided according to actual requirements to improve the friction between the first terminal portion 41 and the insulating block 2 and enhance the reliability of fixing the first terminal portion 41 in the receiving hole 21.

[0098] Please continue to refer to Figure 2 and Figure 3 , the metal housing 1 in the present application further includes a second housing 12. The second housing 12 is connected to the first housing 11, and the second housing 12 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 may be an integrally formed structure, or the first housing 11 and the second housing 12 may be prepared separately, and the first housing 11 and the second housing 12 are connected by using a connection process such as welding.

[0099] Please continue to refer to Figure 3 , the second housing 12 has an opening opposite to the insulating block 2. The insulating block 2 extends into the metal housing 1 from the opening, and a part of the structure of the insulating block 2 extends into the first housing 11. The second housing 12 is detachably assembled with a metal plate 121. The metal plate 121 is located on the side of the second terminal portion 42 facing away from the plug-in end 00. The second housing 12 and the metal plate 121 can also shield the interference of the terminal 4 and improve the signal transmission performance of the high-speed connector 100.

[0100] There are various options for specifically realizing the detachable assembly of the metal plate 121 and the second housing 12, which are not limited in the present application. For example, the metal plate 121 can be fixed to the second housing 12 by using screws; or the metal plate 121 and the second housing 12 can be snap-fitted.

[0101] Figure 14 This is a schematic diagram of a backside structure of a high-speed connector in an embodiment of the present application. Figure 15This is a schematic structural diagram of removing the metal plate 121 in the embodiment of the present application. Figure 16 This is a schematic structural diagram of the metal plate 121 in the embodiment of the present application. As Figure 14 , Figure 15 and Figure 16 shown, the second housing 12 can include a slot 122, and the metal plate 121 is inserted into the slot 122. As Figure 16 shown, the surface of the metal plate 121 further includes one or more protrusions 1211. The protrusions 1211 are located on the surface of the metal plate 121 facing the insulating block 2, and the protrusions 1211 are in contact with 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 it is not easy to fall off from the slot 122, thereby improving the shielding reliability of the high-speed connector 100.

[0102] As Figure 16 shown, in an alternative embodiment, the protrusion 1211 is a circular protrusion. When the metal plate 121 can include multiple protrusions 1211, the multiple protrusions 1211 are arranged at intervals in a straight line direction.

[0103] A cut-off corner can also be provided at the corner of the metal plate 121. Correspondingly, the second housing 12 also has a protrusion portion adapted to the cut-off corner. The cut-off corner and the protrusion portion serve as an anti-fooling structure for the metal plate 121, so that the protrusion portion can be oriented towards the insulation.

[0104] Figure 17 This is a schematic structural diagram of the protective sleeve 3 in the embodiment of the present application. As Figure 2 , Figure 3 and Figure 17 shown, the protective sleeve 3 in the embodiment of the present application can be an insulating protective sleeve. The insulating protective sleeve is sleeved on the outside of the first housing 11 and is fixedly assembled with the metal housing 1. Figure 18 This is a front structural diagram of the protective sleeve 3 in the embodiment of the present application. As Figure 17 and Figure 18 shown, the inner side of the protective sleeve 3 facing the first housing 11 includes at least one guiding groove 31. The guiding groove 31 extends along the insertion and extraction direction M of the high-speed connector 100. The guiding groove 31 can serve as a guiding structure for the mating connector to be inserted into the connector in this embodiment, facilitating the relatively smooth insertion of the two high-speed connectors 100. In this solution, the number and position of the guiding grooves 31 of different types of high-speed connectors can be different, so that the guiding grooves 31 can also serve as an anti-fooling structure to prevent the misinsertion of high-speed connectors with different functions and models.

[0105] Figure 19 This is a schematic diagram of different setting methods of the guiding grooves of the protective sleeve in the embodiment of the present application. As Figure 19As shown, by adjusting the number and position of the guiding grooves, different types of high-speed connectors can be easily distinguished, and incorrect insertion is not likely to occur.

[0106] In addition, as Figure 17 and Figure 18 shown, the above-mentioned protective sleeve 3 includes a first side plate 32, a second side plate 33, a third side plate 34 and a clamping plate 35. The first side plate 32 and the second side plate 33 are arranged opposite to each other, and the third side plate 34 and the clamping plate 35 are arranged opposite to each other. The distance between the clamping plate 35 and the third side plate 34 is greater than the distance between one end of the first side plate 32 away from the third side plate 34 and the third side plate 34. The clamping plate 35 and the first side plate 32 are connected by a first arc plate 36; the distance between the clamping plate 35 and the third side plate 34 is greater than the distance between one end of the second side plate 33 away from the third side plate 34 and the third side plate 34. The clamping plate 35 and the second side plate 33 are connected by a second arc plate 37. Understanding that the four sides of the above-mentioned protective sleeve 3 are approximately flat, the above-mentioned clamping plate 35 can be considered as an arched clamping plate 35, protruding from the plane of the side of the protective sleeve 3. Specifically, the above-mentioned first arc plate 36, clamping plate 35 and second arc plate 37 enclose to form a bayonet. Both ends of the clamping plate 35 are connected to the side plates at both ends through arc plates, which improves the force form of the clamping plate 35 and is beneficial to enhancing the structural strength of the protective sleeve 3.

[0107] To enhance the strength of the bayonet of the protective sleeve 3, reinforcing parts such as reinforcing ribs or reinforcing blocks can also be added to the first arc plate and the second arc plate, so that the structural strength of the positions where the first arc plate and the second arc plate are located is relatively strong, and the connection strength between the clamping plate 35 and the first side plate 32 and the second side plate 33 is relatively strong, and it is not easy to be damaged.

[0108] As Figure 2 , Figure 3 and Figure 17 shown, in one embodiment, in order to realize the fixed assembly of the protective sleeve 3 and the metal shell 1, the above-mentioned protective sleeve 3 includes a through hole 38, and the metal shell 1 includes a clamping groove 13. The above-mentioned high-speed connector 100 includes a stop pin 5, and the stop pin 5 passes through the through hole 38 and is clamped in the clamping groove 13. Thus, the fixed assembly of the protective sleeve 3 and the metal shell 1 is realized.

[0109] Figure 20 This is a schematic structural diagram of the stop pin 5 in the embodiment of the present application. Please combine Figure 20 , the surface of the stop pin 5 also includes a convex bump, which abuts against the through hole 38 or the clamping groove 13 of the above-mentioned protective sleeve 3 to improve the reliability of the stop pin 5 fixed in the through hole 38 and the clamping groove 13. Specifically, the above-mentioned convex bump can be a circular convex bump, so as to simplify the preparation process of the stop pin 5.

[0110] In a specific embodiment, the convex hulls on the surface of the above-mentioned stop pin 5 specifically include a first convex hull 51 and a second convex hull 52. The first convex hull 51 abuts against the inner wall of the through hole 38 of the protective sleeve 3, and the second convex hull 52 abuts against the side wall of the card slot 13 of the metal housing 1. The area of the orthographic projection of the second convex hull 52 on the surface of the stop pin 5 is larger than the area of the orthographic projection of the first convex hull 51 on the surface of the stop pin 5. Due to the different deformation amounts of the surfaces of the metal housing 1 and the insulating block 2, and the area of the second convex hull 52 being larger than that of the first convex hull 51, the contact area between the stop pin 5 and the surface of the metal housing 1 is larger than the contact area between the stop pin 5 and the insulating block 2, enabling the stop pin 5 to be relatively reliably fixed to the above-mentioned metal housing 1 and insulating block 2 respectively, and improving the reliability of the fixed assembly of the protective sleeve 3 and the metal housing 1.

[0111] Based on the same inventive concept, the present application also provides a signal transmission method, specifically a method for transmitting signals using the high-speed connector in the above-mentioned embodiment. Specifically, the terminals of the above-mentioned high-speed connector include power terminals and communication terminals, and the above-mentioned signal transmission method specifically includes: transmitting power signals through the power terminals; transmitting communication signals through the communication terminals. This signal transmission method has a relatively fast signal transmission speed and low loss.

[0112] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
