Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a connector, connector module and communication device. Background Technology

[0002] Communication equipment, as a crucial component of signal transmission, is widely used in technologies such as computers, networks, servers, and high-end storage, and is an essential part of modern communications. In future communication fields, particularly in AI computing, the transmission rate of communication equipment becomes paramount as algorithm performance improves. Connectors, as a key part of the interconnection system within communication equipment, must be designed to meet high-speed transmission requirements while ensuring signal integrity. Currently, mainstream connectors are moving towards transmission rates of 224G / 448G.

[0003] However, connectors are currently trending towards miniaturization and integration, requiring more transmission lines within a smaller space to achieve faster transmission rates. Furthermore, the demand for signal transmission bandwidth is increasing to achieve higher data transmission speeds. However, with a high density of signal transmission components (e.g., differential signal transmission terminal pairs), the spacing between adjacent components is small, leading to significant crosstalk. This reduces the effective transmission bandwidth while maintaining signal integrity, resulting in a decrease in signal transmission rate. While increasing the distance between signal transmission components can reduce crosstalk during high-speed signal transmission, it hinders connector miniaturization and high-density design.

[0004] In summary, existing connector technologies struggle to simultaneously achieve miniaturization and high density while further improving signal transmission rates. Summary of the Invention

[0005] The connectors, connector modules, and communication devices provided in this application solve the problem that connectors in the prior art are difficult to improve their signal transmission rate while meeting the requirements of miniaturization and high density.

[0006] A first aspect of this application provides a connector including a signal transmission module, wherein the signal transmission module includes an insulating mounting base, a plurality of signal transmission parts, and a shielding structure.

[0007] Multiple signal transmission units are fixed to an insulating base and arranged sequentially at intervals in a first direction. Each signal transmission unit includes two signal transmission terminals spaced apart in the first direction, and each signal transmission unit has a first end and a second end. The first end is used to connect to a corresponding signal transmission unit of another connector. A shielding structure is fixed to the insulating base and includes a shielding member disposed on one side of the multiple signal transmission units in a second direction, and spaced apart from each signal transmission unit in the second direction. The second direction is perpendicular to the first direction. Furthermore, no shielding structure is provided between the first portions of any two adjacent signal transmission units; the first portion of each signal transmission unit is the portion of the signal transmission unit excluding the second end.

[0008] The connector signal transmission module provided in this application embodiment is provided with a plurality of signal transmission parts arranged sequentially at intervals in a first direction. Each signal transmission part includes two signal transmission terminals arranged at intervals in the first direction (for example, each signal transmission part is configured as a differential signal transmission terminal pair). Each signal transmission part has a first end and a second end. The first end of the signal transmission part is used to connect with the corresponding signal transmission part of another connector, so that the signal transmission part in the connector is electrically connected to the corresponding signal transmission part of another connector to transmit communication signals (for example, differential pair signals).

[0009] In this connector, a shield is provided on one side of each of the multiple signal transmission sections along the second direction, and the shield is spaced apart from each signal transmission section in the second direction. The surface of the shield facing each signal transmission section serves as a reference ground plane for that section, ensuring a closed signal return path and guaranteeing the integrity of signal transmission within the connector. Furthermore, while maintaining a constant spacing between adjacent signal transmission sections, the shield reduces crosstalk between adjacent sections during signal transmission. This increases the effective transmission bandwidth while ensuring signal integrity, thereby further improving the signal transmission rate.

[0010] As can be seen from the above, in the embodiments of this application, for the scenario of multiple signal transmission parts being arranged in a high density in the connector, that is, when the spacing between two adjacent signal transmission parts is limited (small spacing), by setting a shield on one side, the shield is used for grounding to ensure signal return. It can also confine most of the interference signals generated by each signal transmission part to a certain area, reducing the impact of the interference signals on adjacent signal transmission parts. In this way, signal crosstalk between adjacent signal transmission parts can be reduced, and while ensuring the integrity of the transmitted signal, the signal transmission rate is increased and the signal transmission quality is improved.

[0011] Furthermore, no shielding structure is provided between the first parts of any two adjacent signal transmission sections (i.e., the other parts of the signal transmission section excluding the second end). Therefore, the shielding structure of the signal transmission module in the connector has the advantages of simple structure, high reliability, and low cost.

[0012] Therefore, the connector provided in this application embodiment can achieve miniaturization and high density while further improving the signal transmission rate of the connector. Furthermore, the connector has a simple structure, high reliability, and low cost.

[0013] In one possible implementation, the shielding member extends along a first direction and has a first side and a second side disposed opposite to each other in the first direction, and a plurality of signal transmission units are located between the first side and the second side of the shielding member in the first direction. Each signal transmission unit is disposed overlapping the shielding member in its length direction.

[0014] By adopting the above scheme, the shield extends along the arrangement direction of the signal transmission section, so that multiple signal transmission sections in this direction are located within the coverage area of ​​the shield, ensuring the integrity of signal return and grounding during signal transmission, thereby reducing crosstalk and improving the signal transmission rate and quality.

[0015] In one possible implementation, the second end of the signal transmission unit is provided with additional shielding members on both sides in the first direction, and the additional shielding members are fixed to the shielding members.

[0016] Using the above solution, an additional shield is placed between the second ends of two adjacent signal transmission sections to specifically isolate crosstalk phenomena that exist at the locations where the second ends of each signal transmission section are electrically connected to other devices, thereby reducing crosstalk.

[0017] In one possible implementation, the shielding element is configured as a sheet or a block structure. When the connector has an additional shielding element, the additional shielding element is configured as a sheet or a block structure.

[0018] In one possible implementation, any two adjacent signal transmission sections are spaced apart by a first spacing, the two signal transmission terminals of each signal transmission section are spaced apart by a second spacing, and the signal transmission section and the shielding member are spaced apart by a third spacing.

[0019] In each signal transmission section of the signal transmission module, the corresponding second and third spacings are configured to be related to the corresponding first spacing.

[0020] By employing the above scheme, with a fixed first spacing (i.e., a fixed distance between adjacent signal transmission units), and utilizing the principle of high-speed signal electromagnetic field coupling, the second spacing (i.e., the distance between the two signal transmission terminals of the signal transmission unit) and the third spacing (i.e., the distance between the signal transmission unit and the shielding component) are reduced. This leverages the tight coupling characteristic of differential signal transmission terminal pairs (i.e., setting a smaller distance between the two signal transmission terminals of a differential signal transmission terminal pair) and the proximity of the differential signal transmission terminal pairs to the reference ground plane. This concentrates a large portion of the interference signals (e.g., electromagnetic field signals) generated during signal transmission by each differential signal transmission terminal pair within a certain area, significantly reducing the degree to which these interference signals couple to adjacent differential signal transmission terminal pairs, thereby substantially reducing signal crosstalk. Therefore, without the need for complex shielding structures, signal crosstalk between adjacent signal transmission units can be significantly reduced. While ensuring signal transmission integrity, this improves signal transmission rate and quality, reduces production costs, and enhances reliability.

[0021] In one possible implementation, in the signal transmission module, multiple signal transmission units are not shielded on the other side in the second direction.

[0022] Using the above solution, the signal transmission module only has a shield on one side in the second direction, which can reduce signal crosstalk. Its structure is simple and helps to save production costs and reduce processing time.

[0023] A second aspect of this application provides a connector module, including a first connector and a second connector, wherein both the first connector and the second connector adopt the connectors provided by the first aspect above and any possible implementation thereof, and the first ends of the corresponding signal transmission parts of the first connector and the second connector are in contact and electrically connected.

[0024] The connector module provided in this application adopts the connector provided in the first aspect above and any possible implementation thereof. While satisfying miniaturization and high density, it can further improve the signal transmission rate of the connector and improve the overall performance of the connector module.

[0025] In one possible implementation, the first end of the signal transmission terminal in the first connector includes a spring, which elastically abuts against the first end of the corresponding signal transmission terminal in the second connector. In the signal transmission section, the first ends of the two signal transmission terminals together constitute the first end of the signal transmission section.

[0026] The above solution provides a spring piece at the first end of the signal transmission terminal in the first connector. The spring piece can elastically abut against the first end of the corresponding signal transmission terminal in the second connector to achieve electrical connection between the first connector and the second connector. It can also improve the reliability of the connection between the corresponding signal transmission parts of the first connector and the second connector and ensure the stability of signal transmission.

[0027] In one possible implementation, the shielding structure in the first connector is a first shielding structure, and the corresponding shielding component is a first shielding component. The shielding structure in the second connector is a second shielding structure, and the corresponding shielding component is a second shielding component.

[0028] The first shielding member and the corresponding second shielding member are elastically abutted at their opposite ends.

[0029] By employing the above solution, the first shield in the first connector and the second shield in the second connector elastically abut against each other, forming a closed grounding path between the connectors, enabling signal return and ensuring the integrity of signal transmission. Simultaneously, for the area connecting the corresponding signal transmission sections of the first and second connectors, signal crosstalk between adjacent signal transmission channels can be reduced. Furthermore, the reliability of the connection between the first and second shields can be guaranteed.

[0030] In one possible implementation, the first shielding component includes a first shielding portion and a second shielding portion, which are sequentially connected and relatively fixed in a third direction, wherein the third direction is perpendicular to the first direction and the second direction, respectively.

[0031] The first shielding part is configured as follows: a first shielding sheet with an integral structure; the second shielding part includes a plurality of second shielding sheets arranged sequentially at intervals in a first direction, one end of each second shielding sheet being connected to the first shielding sheet, and the other end being elastically abutting against the second shielding component corresponding to the second connector.

[0032] The above solution includes a first shielding plate and multiple second shielding plates, the specific form of which is not limited, thus the design is flexible and can be selected according to the actual application. Multiple second shielding plates are used to elastically abut against the second shielding plate corresponding to the second connector, which improves the stability of the structural fit while ensuring signal return, and makes the connector more reliable.

[0033] In one possible implementation, in the first connector, a plurality of second shielding plates are arranged in a one-to-one correspondence with a plurality of signal transmission sections, and a gap is formed between any two adjacent second shielding plates, the gap being located between adjacent signal transmission sections in a first direction.

[0034] Using the above scheme, gaps exist between the multiple second shielding plates in the first connector, making the second shielding plates more prone to elastic deformation. This allows for better elastic contact with corresponding positions on the second shielding component, improving the reliability of the shielding structure connection. The gaps are located between adjacent signal transmission sections in the first direction, providing better shielding performance compared to gaps located within the coverage area of ​​a single signal transmission section.

[0035] In one possible implementation, each second shielding sheet is configured as an integral structure with the first shielding sheet.

[0036] Using the above solution, the first shielding component is an integrated structure, which is simple to process and facilitates the uniformity of the overall structure of the signal transmission unit, thereby improving stability.

[0037] In one possible implementation, the surface of the second shield facing the signal transmission section is provided with a plurality of raised spring contacts, which are spaced apart in a first direction, and each spring contact elastically abuts against the first shield.

[0038] By adopting the above scheme, the first shielding component elastically abuts against the spring-loaded part of the second shielding component, making the electrical connection between the first connector and the second connector more stable and ensuring the stability of signal return during signal transmission.

[0039] A third aspect of this application provides a communication device, including the connector module provided in the second aspect above and any possible implementation thereof.

[0040] The communication device provided in this application embodiment has a connector module that, while meeting the requirements of miniaturization and high-density design, can reduce signal crosstalk, ensure the signal transmission rate and quality, and thus enable the connector module to achieve stable signal transmission between system hardware, ensuring the stable operation of the communication device.

[0041] In one possible implementation, the communication device further includes a circuit board, wherein the shielding structure in the first connector is electrically connected to the ground plane of the circuit board, and the second end of each signal transmission section in the first connector is electrically connected to the trace layer of the circuit board.

[0042] The communication equipment also includes cables, each cable corresponding to a signal transmission section of the second connector, the shielding layer of each cable being electrically connected to the shielding structure of the second connector, and the signal core of each cable being electrically connected to the signal transmission terminal of the corresponding signal transmission section in the second connector.

[0099] The following specific embodiments illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Although the description of this application will be presented in conjunction with some embodiments, this does not mean that the features of this application are limited to this embodiment. On the contrary, the purpose of describing the application in conjunction with embodiments is to cover other options or modifications that may be derived based on the claims of this application. To provide a thorough understanding of this application, many specific details will be included in the following description. This application may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this application, some specific details will be omitted in the description. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0100] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0101] The following explains the terminology that may appear in the embodiments of this application.

[0102] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0103] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0104] In the description of this application, it should be understood that "electrical connection" can be understood as physical contact and electrical conduction between components; it can also be understood as the form in which different components in a circuit structure are connected through physical lines that can transmit electrical signals, such as copper foil or wires on a printed circuit board (PCB).

[0105] In the description of this application, it should be noted that the mutual perpendicularity in this application is not absolute perpendicularity. Approximate perpendicularity due to processing and assembly errors (e.g., an angle of 89° between two structural features) is also within the scope of mutual perpendicularity in this application. Similarly, the mutual parallelism in this application is not absolute parallelism. Approximate parallelism due to processing and assembly errors (e.g., an angle of 1° between two structural features) is also within the scope of mutual parallelism in this application.

Approximate central symmetry due to processing and assembly errors (e.g., a partial structure offset by a certain distance or angle relative to the axis of symmetry) is also within the scope of central symmetry in this application. This application does not impose specific limitations in these respects.

[0106] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0107] Currently, connectors play a crucial role in communication equipment, serving as key components for achieving high-speed data transmission. To meet the design requirements of 224G / 448G transmission rates, more transmission lines need to be integrated into connectors to achieve miniaturization and high-density design. However, with a high layout density of signal transmission sections (e.g., differential signal transmission terminal pairs), crosstalk between adjacent signal transmission sections becomes severe, reducing both signal integrity and transmission rate, failing to meet requirements. Alternatively, increasing the distance between signal transmission sections can reduce crosstalk during high-speed signal transmission, but this is detrimental to connector miniaturization and high-density design. The following detailed description, using an exemplary connector structure, illustrates this point.

[0108] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a connector.

[0109] like Figure 1As shown, connector 500' includes one or more signal transmission modules 510'. Each signal transmission module 510' typically contains multiple signal transmission sections 520', which are fixed relative to each other by insulating mounting bases 511'. Each signal transmission section 520' consists of two spaced-apart signal transmission terminals 521', or can be understood as a differential signal terminal pair, where the signal transmission sections 520' and the signal transmission terminals 521' are differential signal terminals, capable of transmitting communication signals within connector 500'. When connector 500' transmits high-speed signals, most of the interference signals (e.g., electromagnetic field signals) generated by the signal transmission sections 520' will couple to adjacent signal transmission sections 520', potentially causing signal distortion and loss, affecting communication quality and system performance. Therefore, with the trend towards miniaturization and high-density connector design, the spacing between adjacent signal transmission sections is small, leading to severe crosstalk and a lower signal transmission rate.

[0110] Based on this, this application provides a connector that, by incorporating a shielding structure in the signal transmission module, enables the connector to further improve its signal transmission rate while meeting the requirements of miniaturization and high density. Furthermore, the connector has a simple structure, high reliability, and low cost.

[0111] This application also provides a connector module and a communication device. By using this connector, signal crosstalk during signal transmission can be reduced, ensuring the rate and quality of signal transmission in the communication device. Thus, the connector module can achieve stable signal transmission between system hardware, ensuring the stable operation of the communication device.

[0112] It should be noted that there are no restrictions on the specific type of communication equipment. Specifically, communication equipment can be devices such as routers, switches, core routers, aggregation routers, rack switches, and transmission switches, as well as base stations, terminal equipment, vehicle-mounted equipment, servers, supercomputers, etc.

[0113] The following section first explains the relevant terms involved in the embodiments of this application.

[0114] Crosstalk refers to the electromagnetic field generated by signal changes during transmission at a signal transmission point (e.g., a differential signal transmission terminal pair). This electromagnetic field can propagate through space or wires, affecting adjacent signal transmission points and causing signal interference or unintended energy transfer. The more severe the crosstalk, the greater the impact between adjacent signal transmission points, the worse the signal transmission integrity, and the more severe the data distortion. Furthermore, as connectors evolve towards higher speeds, the rapid changes in signals further amplify this effect, leading to signal distortion, data errors, and noise interference. Moreover, because high-speed signals have higher effective frequencies, any crosstalk can cause changes in signal timing and voltage amplitude, affecting the correct response at the receiving end. This necessitates stricter control of crosstalk intensity for high-speed signals.

[0115] Bandwidth typically refers to the frequency range occupied by a signal, measured in Hertz (Hz), and indicates the frequency range that a connector can transmit.

[0116] Transmission rate refers to the amount of data transmitted per unit of time, usually measured in bits per second (bps). Generally speaking, the larger the bandwidth, the higher the transmission rate. This is because a wider bandwidth can accommodate more frequency components, thus allowing more data to be transmitted.

[0117] Near-end crosstalk refers to crosstalk measured at the transmitting end caused by signal transmission on another pair of lines. In other words, when two lines are physically close, a signal on one line will induce a voltage on the other line, and this induced voltage is measured at the transmitting end.

[0118] Far-end crosstalk refers to crosstalk caused by signal transmission on another pair of lines, measured at the receiving end. In other words, when a signal on one line affects another line, this effect is measured at the receiving end.

[0119] The following will describe the scenarios in which connector modules are used in communication equipment, with reference to the accompanying drawings.

[0120] Please see Figure 2 , Figure 2 This is a schematic diagram of signal transmission of a communication device according to an embodiment of this application.

[0121] like Figure 2 As shown, the communication device 100 includes a first electronic unit 110, a second electronic unit 120, and a connector module 200. The first electronic unit 110 and the second electronic unit 120 can be connected for communication via the connector module 200. It should be noted that this embodiment does not limit the number or location of the connector modules 200 in the communication device 100; those skilled in the art can select them according to actual needs.

[0122] Furthermore, the connector module 200 includes a first connector 300 and a second connector 400. Corresponding signal transmission parts (e.g., differential signal transmission terminal pairs) between the first connector 300 and the second connector 400 are in contact and electrically connected to transmit signals (e.g., differential signals) between them. That is, the first electronic unit 110 achieves a communication connection with the second electronic unit 120 through the first connector 300 and the second connector 400. The specific structure of the connector module 200, the first connector 300, and the second connector 400 will be described in detail later.

[0123] It should be noted that the specific types of the first electronic unit 110 and the second electronic unit 120 are not limited in the embodiments of this application. In one possible implementation, the first electronic unit 110 may include a first electronic device (e.g., a signal processing module, etc.), and the second electronic unit may include a second electronic device (e.g., an optical module, etc.). The first electronic device of the first electronic unit 110 is communicatively connected to the second electronic device of the second electronic unit 120 through the first connector 300 and the second connector 400. It should also be noted that the first electronic unit 110 may include a power module, which can supply power to the second electronic device of the second electronic unit 120 through the first connector 300 and the second connector 400 in sequence. The second electronic unit 120 may also include a power module, which can supply power to the first electronic device of the first electronic unit 110 through the second connector 400 and the first connector 300 in sequence. That is to say, in addition to transmitting the differential signals mentioned above, the connector module 200 can also transmit power signals, and the embodiments of this application do not limit this.

[0124] Furthermore, the communication connection between the first electronic device of the first electronic unit 110 and the first connector 300 is not limited. In one possible implementation, the first electronic unit 110 also includes a circuit board 130 (see...). Figure 3a and Figure 3b The circuit board may be, for example, a PCB board. The first electronic device is disposed on and electrically connected to the circuit board 130. The first connector 300 is fixed (e.g., soldered) and electrically connected to the circuit board 130. The first connector 300 communicates with the first electronic device through the circuit board 130.

[0125] In other possible implementations, the first electronic unit 110 may also include a cable (not shown in the figure), with both ends of the cable electrically connected to the first electronic device and the first connector 300, respectively, and the first connector 300 communicating with the first electronic device through the cable; or, the first electronic unit 110 may include a cable and a circuit board, with the first electronic device disposed on and electrically connected to the circuit board, and both ends of the cable electrically connected to the first electronic device and the first connector 300, respectively, and the first connector 300 communicating with the first electronic device in sequence through the cable and the circuit board.

[0126] Similarly, the communication connection method between the second electronic device of the second electronic unit 120 and the second connector 400 is not limited, and the communication connection method between the first electronic device and the first connector 300 described above can also be used. For example, the second connector 400 can communicate with the second electronic device through a circuit board, or through a cable, or sequentially through a cable and a circuit board. This will not be elaborated further in the embodiments of this application.

[0127] The above text provides a principled introduction to the application scenarios and basic structure of the connector module 200 in the communication device 100. The following text will first explain the specific application of the connector module 200 when the communication device 100 is a router, with reference to the attached diagram.

[0128] Please see Figure 3a and Figure 3b , Figure 3a This is a schematic diagram of a communication device according to an embodiment of this application in an application scenario. Figure 3b This is a schematic diagram illustrating the communication device according to an embodiment of this application in another application scenario. It should be noted that... Figure 3a and Figure 3b This is for illustrative purposes only, primarily to illustrate the signal transmission path of communication equipment. The structure and placement of the components shown do not impose limitations on the actual product. Furthermore, the actual product may include more or fewer components than those illustrated in the diagram.

[0129] like Figure 3a As shown, in one possible implementation, the communication device 100 is a router. Specifically, the first electronic unit 110 includes a circuit board 130, which is stacked and electrically connected to the first connector 300. The specific type of the circuit board 130 is not limited. In one example, the circuit board 130 is a PCB board, such as a double-sided board, a multilayer board, or an ultra-high density (UHD) board.

[0130] In one possible implementation, the first electronic unit 110 may further include a signal processing module 112. The signal processing module 112 is disposed on the circuit board 130 and electrically connected to the first connector 300 via the circuit board 130. The first electronic unit 110 may also include a heat sink 113, which is stacked on top of the signal processing module 112, with the heat sink 113 located on the side of the signal processing module 112 furthest from the circuit board 130. This provides an effective heat dissipation path for the signal processing module 112, ensuring that the communication device 100 can maintain a relatively stable operating environment for the signal processing module 112 even during prolonged operation.

[0131] It should be noted that the specific type of signal processing module 112 (e.g., a chip) is not limited. For example, in one possible implementation, the signal processing module 112 may include components such as a central processing unit (CPU), a graphics processing unit (GPU), and a data processing unit (DPU).

[0132] Those skilled in the art will understand that the components connected to the signal processing module 112 via the connector module 200 are not limited thereto.

[0133] like Figure 3a As shown, in one possible implementation, the second electronic unit 120 may include a connection module 121, which is electrically connected to the second connector 400 of the connector module 200 via a cable 122. Furthermore, the connection module 121 is used to electrically connect to a second electronic device (not shown) in the second electronic unit 120. This allows the second electronic device to sequentially pass through the connection module 121, the cable 122, and the second signal transmission section 420 of the second connector 400 (see...). Figure 9 ), the first signal transmission section 320 of the first connector 300 (see Figure 8dThe circuit board 130 is electrically connected to the signal processing module 112 to realize signal transmission between the second electronic device and the signal processing module 112. Exemplarily, the connection module 121 can be used to plug in an optical module (not shown in the figure). Specifically, the optical module can be different types of optical modules such as Small Form-Pluggable (SFP), Dual Small Form Factor Pluggable (DSFP), Quad Small Form Factor Pluggable (QSFP), and Quad Small Form Factor Pluggable-Double Density (QSFP DD). This application embodiment is not limited herein. Exemplarily, the connection module 121 on the circuit board 130 can be plugged into and electrically connected to the connection module 121 of another circuit board. In this case, the circuit board 130 can be a single board 111, and the other circuit board can be a backplane.

[0134] The following will combine Figure 3b When the communication device 100 is a server, the specific application of the connector module 200 will be explained.

[0135] In one possible implementation, the communication device 100 is a server. Specifically, such as... Figure 3b As shown, the communication device 100 has a circuit board 130 (in one example, the circuit board 130 can be a backplane 114) inside, which is used to realize communication and electrical connection between the various functional modules inside. That is, the first electronic unit 110 includes a backplane 114 and a hard disk module 115. The hard disk module 115 is plugged into the backplane 114 and can read and write data.

[0136] The communication device 100 also includes a motherboard 123, a power module 116, and a heat sink 113. The motherboard 123 is a core component of the communication device 100's hardware system, compatible with various hardware components including data processing modules, hard disk modules 115, memory 125, storage devices, and network devices. Essentially, the motherboard 123 provides a platform for connecting and communicating with various hardware devices. The power module 116 is electrically connected to the motherboard 123 and supplies power to the devices on the motherboard 123. It should be noted that the power module 116 can also be electrically connected to the motherboard 123 via connector module 200; this embodiment does not limit this connection. Those skilled in the art will understand that this embodiment does not limit the specific structure and location of the heat sink 113. The heat sink 113 can be configured as an air-cooling system (e.g., a fan) to provide heat dissipation support for the communication device 100. Air cooling prevents components such as the data processing module, hard disk module 115, and memory 125 from being damaged or experiencing performance degradation due to overheating, thereby ensuring the normal operation of the communication device 100. It is understood that the second electronic unit 120 may include a motherboard 123, a power module 116, a heat sink 113, and various other hardware.

[0137] Furthermore, in one possible implementation, such as Figure 3b As shown, the first connector 300 of the connector module 200 is electrically connected to the backplane 114, and the second connector 400 is electrically connected to the motherboard 123 via cable 122. This allows signals from the data processing module in the communication device 100 to be transmitted sequentially through the motherboard 123, cable 122, the second signal transmission section 420 of the second connector 400, and the first signal transmission section 320 of the first connector 300 to the backplane 114, enabling communication with the hard disk module 115 and thus facilitating the function activation of the corresponding functional modules in the communication device 100. It should be noted that in other possible implementations, the connector module 200 can also be placed between the motherboard 123 and cable 122; this embodiment does not limit this. The specific type of the data processing module is not limited and may include a Redundant Array of Independent Disks Controller (RAID controller) 124A, a Baseboard Management Controller (BMC) 124B, or a Central Processing Unit (CPU) 124C, etc.

[0138] Furthermore, this application embodiment does not limit the number of connector modules 200 in the communication device 100. Those skilled in the art can make corresponding settings according to the implementation of the functions between the modules in the communication device 100.

[0139] It should be noted that the above is merely an exemplary description of the application scenario of connector module 200 in communication device 100, and does not constitute a specific limitation on the application scenario of the embodiments of this application. The basic structure of a connector will be described in detail below with reference to the accompanying drawings. It should be noted that the first connector 300 can be the connector 500 described below, the second connector 400 can also be the connector 500 described below, or both the first connector 300 and the second connector 400 can be the connector 500 described below; this application embodiment does not impose any limitations on this. The specific structures of the first connector 300 and the second connector 400 will be described in detail later. The basic structure and communication principle of connector 500 will be described first below.

[0140] Please see Figures 4a-4c , Figures 4a-4c This is a schematic diagram of various arrangements of the signal transmission module of the connector in the embodiments of this application.

[0141] like Figures 4a-4c As shown, the connector 500 includes one or more signal transmission modules 510. Each signal transmission module 510 includes multiple signal transmission sections arranged sequentially and relatively fixed. The signal transmission sections are used to transmit differential signals in the communication device 100, which is more stable and reliable during high-speed transmission.

[0142] In one possible implementation, connector 500 includes multiple signal transmission modules 510. These multiple signal transmission modules 510 can be arranged in an array to transmit signals together, enabling high-speed communication of connector 500. That is, the first connector 300 may include multiple first signal transmission modules 310, and the second connector 400 may include multiple second signal transmission modules 410. In one example, such as... Figure 4c As shown, multiple signal transmission modules 510 are arranged in the first direction x and the second direction y, which improves the integration of the connector 500 and is beneficial for the miniaturization of the connector 500 and the high-density transmission of communication signals. The first direction x and the second direction y are perpendicular to each other, and both the first direction x and the second direction y are perpendicular to the third direction z. In other examples, such as... Figure 4a As shown, multiple signal transmission modules 510 can also be arranged sequentially in the first direction x, or, as... Figure 4b As shown, multiple signal transmission modules 510 are arranged sequentially in the second direction y, but this embodiment does not limit this arrangement. Furthermore, in other possible implementations, the signal transmission modules 510 may also be arranged opposite to each other; for example, the signal transmission modules 510 may be arranged opposite to each other in the second direction y and spaced apart in the first direction x.

[0143] It should be noted that the first direction x can be the length direction of the insulating fixing base in the signal transmission module, the second direction y can be the height direction of the insulating fixing base in the signal transmission module, and the third direction z can be the width direction of the insulating fixing base. This application embodiment does not impose any limitations on these directions. The basic structure of the insulating fixing base will be explained later.

[0144] Please see Figures 5a-5d , Figure 5a This is a schematic diagram of the signal transmission module in the connector according to an embodiment of this application from one perspective. Figure 5b This is a schematic diagram of the signal transmission module in the connector of this application embodiment. Figure 5c This is a schematic diagram of the signal transmission module in the connector according to an embodiment of this application from another perspective. Figure 5d This is a schematic diagram of another implementation of the signal transmission module in the connector of this application embodiment.

[0145] like Figure 4c and Figure 5a As shown, the signal transmission module 510 includes an insulating mounting base 511 and a plurality of signal transmission units 520. The plurality of signal transmission units 520 are fixed to the insulating mounting base 511 and are arranged sequentially at intervals in the first direction x. Alternatively, it can be understood that the insulating mounting base 511 can be used to fix the signal transmission units 520. The number of signal transmission units 520 can be one, two, three, or more. This embodiment does not limit the number of signal transmission units 520 in the signal transmission module 510. The accompanying drawings are for illustrative purposes only, and those skilled in the art can select the appropriate number based on design needs.

[0146] Furthermore, each signal transmission unit 520 has two signal transmission terminals 530 spaced apart in the first direction x. For example, each signal transmission unit 520 is configured as a differential signal transmission terminal pair for transmitting differential signals, suitable for high-speed signals. Figure 5a As shown, each signal transmission terminal 530 of the signal transmission unit 520 has a first end 531 and a second end 532. The first end 531 and the second end 532 of the signal transmission terminal 530 are located at opposite ends along its length. Specifically, the first end 531 and the second end 532 of the signal transmission terminal 530 can be two ends that are far apart in the third direction z. The length direction of the signal transmission terminal 530 can be understood as the direction in which the extension path of the signal transmission terminal 530 lies. In the signal transmission unit 520, the first ends 531 of two signal transmission terminals 530 together constitute the first end 521 of the signal transmission unit 520, and the second ends 532 of two signal transmission terminals 530 together constitute the second end 522 of the signal transmission unit 520. Furthermore, the portion of the signal transmission unit 520 other than its second end 522 constitutes the first portion 523 of the signal transmission unit 520.

[0147] In this connector 500, the first end 531 of each signal transmission terminal 530 in the signal transmission section 520 is used for connection to the corresponding signal transmission section of another connector, thereby electrically connecting the corresponding signal transmission terminals 530 of each signal transmission section 520 in the two connectors 500 to realize signal transmission.

[0148] It should be noted that, in other possible implementations, the signal transmission module may also include a signal transmission section for transmitting single-terminal signals, or it can be understood that the signal transmission section includes a signal transmission terminal, and the single-terminal signal transmitted by the signal transmission section is suitable for low-speed signals. The signal transmission section for transmitting single-terminal signals is fixed to the insulating mounting base 511 and is spaced apart from the signal transmission section 520 mentioned above in the first direction. The signal transmission module may also include a signal transmission section for transmitting power signals, which is fixed to the insulating mounting base 511 and is spaced apart from the signal transmission section 520 mentioned above in the first direction. This application embodiment does not limit this.

[0149] It should be noted that the specific extension path of the signal transmission terminal 530 is not limited. For example, the signal transmission terminal 530 can extend along at least one of a straight line, a broken line, or a curve.

[0150] It should be noted that each signal transmission terminal 530 of the first signal transmission unit 520 can be an integral structure or a separate structure, and the embodiments of this application do not limit this.

[0151] The specific positional relationship between the insulating mounting base 511 and the signal transmission unit 520 is not limited. For example... Figure 5a As shown, in one possible implementation, the signal transmission section 520 passes through the insulating mounting base 511 along its length, with the first end 521 and the second end 522 of the signal transmission section 520 extending out of the insulating mounting base 511. The entire area of ​​the signal transmission section 520 passing through the insulating mounting base 511 (located between the first end 521 and the second end 522) is enclosed within the insulating mounting base 511; or, in other words, the entire area of ​​the signal transmission section 520 passing through the insulating mounting base 511 is hidden within the insulating mounting base 511. The insulating mounting base 511 ensures the stability of signal transmission between the two signal transmission terminals 530 in the signal transmission section 520, and also secures multiple signal transmission sections 520 together within a certain space, meeting the compact design requirements of the connector 500.

[0152] In other possible implementations, the area of ​​the signal transmission unit 520 that passes through the insulating fixing base 511 may be partially enclosed within the insulating fixing base 511, or it can be understood that the area of ​​the signal transmission unit 520 that passes through the insulating fixing base 511 is partially hidden within the insulating fixing base 511 and partially exposed outside the insulating fixing base 511. This application embodiment does not limit this.

[0153] The material of the insulating mounting base 511 is not limited. In one possible implementation, the insulating mounting base 511 is made of plastic, which is low in cost, simple to process and mold, and can also provide good insulation and protection for the signal transmission terminal 530. In other possible implementations, the insulating mounting base 511 can also be made of plastic or other materials, and this application embodiment does not limit this.

[0154] The basic structure of connector 500 has been described above. It can be understood that connector 500 can internally house one or more signal transmission modules 510. Each signal transmission module 510 includes at least one signal transmission section 520, which comprises two spaced-apart signal transmission terminals 530 (e.g., a differential signal transmission terminal pair). This allows the signal transmission terminals 530 of connector 500 to abut against corresponding signal transmission terminals in another connector, ensuring electrical connection and thus realizing the signal transmission function of connector 500. It should be noted that due to the complementary nature of the signals, the two signal transmission terminals 530 in a differential signal transmission terminal pair do not generate crosstalk between each other, or the degree of crosstalk is extremely low and its impact on signal transmission rate and quality is negligible.

[0155] However, when the spacing between adjacent signal transmission units 520 is small, the signal crosstalk generated between adjacent signal transmission units 520 during signal transmission is quite severe, which will significantly affect the signal transmission rate and quality. To address this, this embodiment of the application provides a shielding structure 540 in the signal transmission module 510, enabling the connector to achieve miniaturization and high density while ensuring the integrity of signal return during signal transmission and significantly reducing the degree of signal crosstalk between adjacent signal transmission units, thereby improving the signal transmission rate and quality.

[0156] The following section will first briefly introduce two reference designs for the shielding structure.

[0157] Please see Figure 7a and Figure 7b , Figure 7a This is a schematic diagram of the signal transmission module in the first reference design. Figure 7b This is a schematic diagram of the signal transmission module in the second reference design.

[0158] In a reference design, such as Figure 7a As shown, for each pair of signal transmission terminals 521” in the signal transmission module 510”, a shielding plate 512” is set around them. This can effectively reduce signal crosstalk between adjacent pairs of signal transmission terminals 521”, thereby reducing the impact on high-speed signal transmission. However, in the design and production process, the design and production requirements for setting the shielding plates 512” around the perimeter are high, and it is necessary to ensure good contact between the shielding plates 512” around the perimeter. This also brings certain difficulties to production and installation. Specifically, by overlapping the shielding plates 512” around each pair of signal transmission terminals 521”, a riveting structure or a complex MIM structure (Metal-Insulator-Metal structure, i.e., metal-insulator-metal structure) is required, which has the problems of complex structure, higher production cost, and high reliability risk.

[0159] In another reference design, such as Figure 7b As shown, for each pair of signal transmission terminals 521"' in the signal transmission module 510"', a shielding sheet 512"' can be arranged to form a semi-enclosed shielding space. That is, shielding sheets 512"' are provided on both sides of the first direction x"' of each pair of signal transmission terminals 521"' (or it can be understood as a shielding sheet 512"' is provided between two pairs of signal transmission terminals 521"'), and a shielding sheet 512"' is provided on one side of the second direction y"' of each pair of signal transmission terminals 521"'. In other words, a shielding sheet 512"' is provided on the side of the signal transmission terminal 521"' away from the insulating fixing base 511"'. The shielding sheet 512"' and the signal transmission terminal 521"' are fixed to the insulating fixing base 511"'. At this time, the shielding sheet 512"' can reduce the signal crosstalk between each adjacent pair of signal transmission terminals 521"' to a certain extent. However, the process is complex, and there are still problems such as high production cost and high reliability risk.

[0160] This application provides a connector that achieves miniaturization and high density while maintaining a simple structure, high reliability, and low cost, and can further improve the signal transmission rate of the connector. The following is combined with... Figures 5a-5c Please provide a detailed description of the connector's shielding structure.

[0161] like Figures 5a-5cAs shown, the signal transmission module 510 includes a shielding structure 540 for signal return and crosstalk reduction during signal transmission. Specifically, the shielding structure 540 is fixed to the insulating mounting base 511, and includes a shielding member 541. The shielding member 541 is disposed on one side of a plurality of signal transmission parts 520 in the second direction y, and is spaced apart from each signal transmission part 520 in the second direction y. Specifically, the shielding member 541 includes a plurality of sub-shielding members 544 arranged sequentially in the first direction x. The plurality of sub-shielding members 544 are disposed one-to-one with the plurality of signal transmission parts 520 of the signal transmission module 510. Each sub-shielding member 544 is disposed on one side of the corresponding signal transmission part 520 in the second direction y, and is spaced apart from the corresponding signal transmission part 520 in the second direction y.

[0162] In this embodiment, each signal transmission unit 520 and its corresponding sub-shielding member 544 are arranged overlapping in the first direction x. It should be noted that the specific way in which the signal transmission unit 520 and its corresponding sub-shielding member 544 overlap in the first direction x is not limited; for example, they may partially overlap or completely overlap. This embodiment does not impose any restrictions on this. Furthermore, the way in which different signal transmission units 520 and their corresponding sub-shielding members 544 overlap in the first direction x may be the same or different. This embodiment does not impose any restrictions on this.

[0163] like Figure 5c As shown, in one possible implementation, the signal transmission section 520 is entirely located between the two sides of the corresponding sub-shield 544 along the first direction x. In this case, the signal transmission section 520 and the corresponding sub-shield 544 completely overlap in the first direction x, which helps to further optimize the crosstalk performance between adjacent signal transmission sections 520 and improve the reliability of signal transmission in the connector. The signal transmission section 520 being entirely located between the two sides of the corresponding sub-shield 544 along the first direction x can include the following situations: in the first direction x, the first side of the signal transmission section 520 is aligned with the first side of the corresponding sub-shield 544; or, located between the two sides of the corresponding sub-shield 544, the second side of the signal transmission section 520 is aligned with the second side of the corresponding sub-shield 544; or, located between the two sides of the corresponding sub-shield 544. Wherein, the first side and second side of the signal transmission section 520 are arranged opposite to each other in the first direction x, and the two opposite sides of the two signal transmission terminals 530 in the first direction x respectively constitute the first side and second side of the signal transmission section 520. The first side and the second side of the sub-shielding member 544 are arranged opposite to each other in the first direction x.

[0164] In other possible implementations, a portion of the signal transmission unit 520 may be located between the two sides of the corresponding sub-shield 544 along the first direction x, and another portion of the signal transmission unit 520 may be located outside the two sides of the corresponding sub-shield 544 along the first direction x. In this case, the signal transmission unit 520 and the corresponding sub-shield 544 partially overlap in the first direction x. Specifically, this may include the following situations: in the first direction x, the first side of the signal transmission unit 520 is located on the side of the first side of the corresponding sub-shield 544 away from the second side, and the second side of the signal transmission unit 520 is located between the two sides of the corresponding sub-shield 544; or, the first side of the signal transmission unit 520 is located between the two sides of the corresponding sub-shield 544, and the second side of the signal transmission unit 520 is located on the side of the second side of the corresponding sub-shield 544 away from the first side.

[0165] Furthermore, in the length direction of the signal transmission section 520, each signal transmission section 520 overlaps with its corresponding sub-shielding member 544, or it can be understood that each signal transmission section 520 overlaps with the shielding member 541 in its length direction. The length direction of the signal transmission section 520 is the direction of the extension path of the two signal transmission terminals 530 of the signal transmission section 520.

[0166] It should be noted that the specific way in which the signal transmission section 520 and the corresponding sub-shielding member 544 overlap in the length direction of the signal transmission section 520 is not limited. For example, they can partially overlap or completely overlap, and this embodiment does not impose any restrictions on this. Furthermore, the way in which different signal transmission sections 520 and their corresponding sub-shielding members 544 overlap in the length direction of the signal transmission section 520 can be the same or different, and this embodiment does not impose any restrictions on this.

[0167] like Figure 5aAs shown, in one possible implementation, the signal transmission section 520 is entirely located between the two ends of the corresponding sub-shield 544 along its length. In this case, the signal transmission section 520 completely overlaps with the corresponding sub-shield 544, so that the entire signal transmission section 520 is within the coverage area of ​​the corresponding sub-shield 544 in this direction. This helps to further optimize the crosstalk performance between adjacent signal transmission sections 520, and can further improve the signal transmission rate and quality. The signal transmission section 520 being entirely located between the two ends of the corresponding sub-shield 544 along its length can include the following situations: the first end 521 of the signal transmission section 520 is aligned with the first end of the corresponding sub-shield 544, or located between the two ends of the corresponding sub-shield 544; the second end 522 of the signal transmission section 520 is aligned with the second end of the corresponding sub-shield 544, or located between the two ends of the corresponding sub-shield 544. The first end of the sub-shield 544 is used to connect to another connector corresponding to the sub-shield.

[0168] In other possible implementations, along the length of the signal transmission section 520, a portion of the signal transmission section 520 may be located between the two ends of the corresponding sub-shield 544, and another portion of the signal transmission section 520 may be located outside the two ends of the corresponding sub-shield 544. In this case, the signal transmission section 520 and the corresponding sub-shield 544 partially overlap along the length of the signal transmission section 520. Specifically, this may include the following situations: along the length of the signal transmission section 520, the first end 521 of the signal transmission section 520 is located on the side of the first end of the corresponding sub-shield 544 away from the second end, and the second end 522 of the signal transmission section 520 is located between the two ends of the corresponding sub-shield 544; or, the first end 521 of the signal transmission section 520 is located between the two ends of the corresponding sub-shield 544, and the second end 522 of the signal transmission section 520 is located on the side of the second end of the corresponding sub-shield 544 away from the first end.

[0169] Those skilled in the art will understand that, in the first direction x, adjacent sub-shields 544 can be spaced apart (see...). Figure 5d They can also be interconnected. When adjacent sub-shields 544 are interconnected, the adjacent sub-shields 544 can adopt an integrated structure (see...). Figure 5c Alternatively, a split structure can be adopted (in which case adjacent sub-shields 544 can be fixed together, for example, by welding), and this application embodiment does not limit this. It should be noted that all adjacent sub-shields 544 can be configured as a single integrated structure (see...). Figure 5c Alternatively, it can be entirely configured as a split structure (see...). Figure 5dIt can also be partially configured as an integrated structure or partially configured as a split structure; the embodiments of this application do not impose any restrictions on this.

[0170] The surface of the shield 541 facing each signal transmission section 520 serves as the reference ground plane for the corresponding signal transmission section 520 (i.e., the surface of each sub-shield 544 facing the corresponding signal transmission section 520 serves as the reference ground plane for the corresponding signal transmission section 520), thus closing the signal return path and ensuring the integrity of signal transmission in the connector. Furthermore, while maintaining a constant spacing between adjacent signal transmission sections 520, the shield 541 reduces crosstalk between adjacent signal transmission sections 520 when each section 520 transmits its own signal. This increases the effective transmission bandwidth while ensuring the integrity of the signal transmission in the connector 500, thereby further improving the signal transmission rate.

[0171] Furthermore, no shielding structure is provided between any two adjacent signal transmission sections 520, specifically the first portions 523. In other words, no shielding structure is provided on either side of the first portions 523 of the signal transmission section 520 in the first direction x. Compared with the reference designs of the two shielding structures mentioned above, the shielding structure 540 of the signal transmission module 510 in the connector 500 of this embodiment has the advantages of simple structure, high reliability, and low cost while ensuring crosstalk performance.

[0172] Therefore, as Figures 5b-5c As shown, in a scenario where multiple signal transmission sections 520 are densely arranged in the connector 500, i.e., when the first spacing L1 (the spacing between two adjacent signal transmission sections 520) is limited (or can be understood as L1 being small), by setting a shield 541 on one side, which is used for grounding, signal return is ensured. This also confines most of the interference signals (e.g., electromagnetic field signals) generated by each signal transmission section 520 to a certain area, making the energy of the interference signal coupled to the adjacent signal transmission section very small. This significantly reduces the impact of the electromagnetic interference signal on the adjacent signal transmission section 520, reduces signal crosstalk between adjacent signal transmission sections, and significantly increases the signal transmission rate and improves the signal transmission quality while ensuring the integrity of the transmitted signal.

[0173] Therefore, in this embodiment, to meet the design requirements of connector miniaturization and high density, the signal transmission rate of the connector can be further improved by setting a shielding structure. Furthermore, the connector has a simple structure, high reliability, and low cost.

[0174] like Figures 5b-5cAs shown, in one possible implementation, in the signal transmission module 510, the other side of the plurality of signal transmission units 520 in the second direction y is not provided with a shielding member, making the shielding structure 540 of the signal transmission module 510 simpler and more reliable, which is beneficial for saving production costs and reducing processing time. In other possible implementations, in the signal transmission module 510, the other side of the plurality of signal transmission units 520 in the second direction y may also be provided with a shielding member. For example, each signal transmission unit 520 may have a corresponding sub-shielding member provided on the other side of the second direction y, or some signal transmission units 520 may have a corresponding sub-shielding member provided on the other side of the second direction y, while some signal transmission units 520 may not have a sub-shielding member provided on the other side of the second direction y.

[0175] Furthermore, with the expansion of computing demands, connectors are moving towards transmission rates of 224G / 448G, requiring the bandwidth of connectors on the link to be extended to 70GHz, and crosstalk reduced to the -50dB to -60dB range. This means that even during high-speed signal transmission, low signal crosstalk must be maintained to ensure communication quality. To better illustrate the improvement in crosstalk performance of connector 500 by this structure, the embodiments of this application also simulated the changes in loss and crosstalk with frequency.

[0176] Please see Figures 6a to 6c , Figure 6a This is a diagram illustrating the signal loss-frequency curve of the connector in an embodiment of this application. Figures 6b-6c This is a diagram illustrating the signal crosstalk-frequency curve effect in the connector of this application embodiment.

[0177] like Figure 6a As shown, during connector signal transmission, signal loss drops sharply when the frequency exceeds 90GHz, while the loss fluctuates slightly when the frequency is below 90GHz. Specifically, the signal transitions smoothly between 0-85GHz, and the loss is negligible, thus meeting the design requirements for high-speed signal transmission in the connector. Figure 6b As shown, at a frequency of 56 GHz, far-end crosstalk (e.g., as...) Figure 5a As shown, the crosstalk signal generated by the second end 522 of the signal transmission unit 520 to the first part of the adjacent signal transmission unit is -43dB, and the far-end crosstalk is -37dB when the frequency is 70GHz. Figure 6c As shown, near-end crosstalk at a frequency of 56 GHz (e.g., as...) Figure 5aAs shown, the crosstalk signal generated by the second end 522 of the signal transmission section 520 to the second end of the adjacent signal transmission section is -60dB, and the near-end crosstalk is -51dB when the frequency is 70GHz. That is, as the signal transmission rate increases, the crosstalk level during the signal transmission of the connector remains basically unchanged, or the crosstalk can be reduced. In other words, the connector provided in this application embodiment can better reduce the crosstalk between signal transmission sections for high-speed transmitted signals, and improve the quality and rate of signal transmission in the connector.

[0178] The following combination Figure 5b The shielding structure 540 in this embodiment reduces signal crosstalk, based on the principle of electromagnetic field coupling. It should be noted that... Figure 5b The dashed line indicates the area where the electromagnetic field is mainly concentrated. In actual scenarios, there is also an electromagnetic field around it, but because its intensity is very low and the degree of signal interference is very low, it is not shown here. It should be noted that, regarding the electromagnetic field generated by a single signal transmission unit 520 during signal transmission, the electromagnetic field strength is greater near the location of the signal transmission unit 520 and lower further away from the location of the signal transmission unit 520.

[0179] like Figure 5b As shown, each pair of signal transmission terminals 530 (i.e., signal transmission section 520) generates an electromagnetic field during signal transmission. By providing a shield 541, most of the energy of this electromagnetic field can be confined within a certain area, thereby making the energy of the electromagnetic field (i.e., interference signal) coupled to adjacent signal transmission sections very small. This significantly reduces the impact of the electromagnetic interference signal on adjacent signal transmission sections 520, thus reducing signal crosstalk between adjacent signal transmission sections 520. For example, as... Figure 5bAs shown, by providing shielding 541, most of the electromagnetic field energy generated by the middle signal transmission unit 520 during signal transmission can be confined to region B. Since the left and right signal transmission units 520 are located outside region B, the electromagnetic field energy confined to region B will not couple to the left and right signal transmission units 520, or the coupling degree will be very low. Similarly, by providing shielding 541, most of the electromagnetic field energy generated by the left signal transmission unit 520 during signal transmission can be confined to region A, and most of the electromagnetic field energy generated by the right signal transmission unit 520 during signal transmission can be confined to region C. When any two regions A, B, and C do not overlap, the degree of crosstalk between adjacent signal transmission units can be reduced to a significant extent. It should be noted that as the signal transmission rate increases, the area occupied by the electromagnetic interference region (e.g., regions A, B, and C mentioned above) also increases, meaning crosstalk is more likely to occur. In simple terms, as signal transmission rates increase, crosstalk between different signal transmission units 520 can be reduced by increasing the distance between them, thereby ensuring signal transmission rate and quality. However, such a design is not conducive to the miniaturization and high-density design of connectors and cannot meet application requirements.

[0180] Therefore, by setting a shielding structure 540 in the signal transmission module 510, the integrity of the signal return flow during signal transmission can be guaranteed, and most of the interference signals generated by the signal transmission unit 520 can be confined to a certain area, reducing the impact of coupling to the adjacent signal transmission unit 520 on its signal transmission, reducing the degree of signal crosstalk, and ensuring the speed and quality of signal transmission.

[0181] like Figure 5cAs shown, in one possible implementation, any two adjacent signal transmission sections 520 are spaced apart by a first gap L1, the two signal transmission terminals 530 of each signal transmission section 520 are spaced apart by a second gap L2, and the signal transmission section 520 and the shielding member 541 are spaced apart by a third gap L3. In each signal transmission section 520 of the signal transmission module 510, the corresponding second gap L2 (i.e., the distance between the two signal transmission terminals 530 of the signal transmission section 520) and the third gap L3 (i.e., the distance between the signal transmission section 520 and the shielding member 541) are related to the corresponding first gap L1. When the first gap L1 is constant, by utilizing the principle of high-speed signal electromagnetic field coupling, by reducing the second gap L2 and the third gap L3, and by utilizing the tight coupling characteristic between the two signal transmission terminals 530 (i.e., a smaller L2) and the short distance from the signal transmission section 520 to the reference ground plane (i.e., a smaller L3), most of the energy of the electromagnetic interference signal generated by each signal transmission section 520 during signal transmission is concentrated and confined to a certain area (see [reference]). Figure 5b Within regions A, B, and C, the energy of the electromagnetic interference signal coupled to adjacent signal transmission units 520 is minimized, thereby significantly reducing the impact of the electromagnetic interference signal on adjacent signal transmission units 520 and reducing signal crosstalk between adjacent signal transmission units 520. Therefore, without the need for a complex shielding structure 540, signal crosstalk between adjacent signal transmission units 520 can be significantly reduced. This ensures signal transmission integrity while improving signal transmission rate and quality, reducing production costs, and increasing reliability.

[0182] It should be noted that, for a single signal transmission unit 520, if its corresponding first spacing L1 remains unchanged, the smaller the corresponding second spacing L2 and third spacing L3, the more concentrated the region where the electromagnetic field generated by the signal transmission unit 520 is confined (e.g., Figure 5b The smaller the regions A, B, and C are, the lower the energy of the electromagnetic interference signal coupled to the adjacent signal transmission unit 520, the smaller the impact on the adjacent signal transmission unit 520, and the lower the degree of signal crosstalk between the adjacent signal transmission units 520.

[0183] Those skilled in the art will understand that the embodiments of this application do not limit the specific values ​​of the first spacing L1, the second spacing L2, and the third spacing L3 mentioned above, and can be reasonably set according to actual needs. For example, regarding the setting of the first spacing L1, based on the miniaturization of the connector 500, more signal transmission parts 520 can be arranged in a limited space, while also taking into account technical factors such as manufacturing process and signal crosstalk, the value of the first spacing L1 can be reasonably set. Regarding the setting of the second spacing L2 and the third spacing L3, given a fixed first spacing L1, based on the miniaturization of the connector 500, more signal transmission parts 520 can be arranged in a limited space, while also taking into account technical factors such as signal transmission rate and signal crosstalk, the values ​​of the second spacing L2 and the third spacing L3 can be reasonably set.

[0184] It should be noted that the specific structure of the shielding component 541 is not limited. In one possible implementation, such as... Figure 5a As shown, the shielding member 541 extends along the first direction x and has a first side surface 542 and a second side surface 543 disposed opposite to each other in the first direction x. A plurality of signal transmission units 520 are located between the first side surface 542 and the second side surface 543 of the shielding member 541 in the first direction x. Alternatively, it can be understood that the plurality of signal transmission units 520 are located entirely within the area corresponding to the shielding member 541 in the first direction x, so that the plurality of signal transmission units 520 are entirely within the coverage area of ​​the shielding member 520, ensuring the integrity of signal return and grounding during signal transmission, thereby reducing crosstalk and improving the rate and quality of signal transmission.

[0185] In one possible implementation, the shielding element 541 can be a one-piece structure; in other possible implementations, the shielding element 541 can be a separate structure. The possible forms of the shielding element will be described in detail later.

[0186] It should be noted that the specific structure of the shielding component 541 is not limited. In one possible implementation, the shielding component 541 is configured as a sheet-like structure (see...). Figure 8d In this case, the sheet-like shielding component has good elastic deformation capability, which can better provide elastic contact with the corresponding position of the other connector, improving the reliability of the connector module. In other possible implementations, the shielding component 541 is configured as a block structure (see...). Figure 9 This structure facilitates the design of other structures (see...). Figure 9 The spring-loaded part 4411 in the middle improves the structural reliability of the connector during electrical connection.

[0187] Generally, the shielding component is made of metal because metal has good conductivity and magnetic permeability. The surface of the metal shielding component reflects and refracts some electromagnetic waves, preventing them from penetrating the shielding component and thus achieving a shielding effect. On the other hand, the interior of the shielding component absorbs some of the energy of the electromagnetic waves and converts it into heat energy, thereby weakening the propagation of electromagnetic waves and reducing the energy that electromagnetic interference signals may couple to adjacent signal transmission units 520, thus reducing the degree of signal crosstalk within the signal transmission module 510. It should be noted that the additional shielding component mentioned later can also be made of metal, which can better shield electromagnetic interference signals between signal transmission units. Furthermore, the grounding pin and signal pin mentioned later can also be made of metal, which has good conductivity.

[0188] The above text mainly describes the specific structure of connector 500 and how to reduce crosstalk. The following text will explain the specific structure and mating relationship of connector module 200 and related components.

[0189] The following description, in conjunction with the accompanying drawings, first illustrates an exemplary structure of the first connector 300.

[0190] Please see Figures 8a-8d , Figure 8a This is a schematic diagram of the signal transmission module of the first connector in the connector module of this application embodiment. Figure 8b This is a front view schematic diagram of the signal transmission module of the first connector in the connector module of this application embodiment. Figure 8c This is a side view of the signal transmission module of the first connector in the connector module of this application embodiment. Figure 8d This is an exploded view of the signal transmission module of the first connector in the connector module of the embodiment of this application.

[0191] It should be noted that the first connector 300 can adopt the specific structure of the connector 500 described above. Accordingly, the first connector 300 includes at least one first signal transmission module 310 (i.e., signal transmission module 510), each first signal transmission module 310 includes a plurality of first signal transmission parts 320 (e.g., differential signal transmission terminal pairs, i.e., signal transmission parts 520), and each first signal transmission part 320 includes two first signal transmission terminals 330 (e.g., differential signal transmission terminals, i.e., signal transmission terminals 530) spaced apart in the first direction x. Those skilled in the art will understand that, in use, the first connector 300 can be designed according to specific requirements, and the embodiments of this application are not limited here.

[0192] The shielding structure of the first connector 300 will be described in detail below.

[0193] The shielding structure in the first connector 300 is the first shielding structure 340 (i.e., shielding structure 540), and the corresponding shielding component is the first shielding component 341 (i.e., shielding component 541). For example... Figure 8a , Figure 8c and Figure 8d As shown, the first shielding member 341 includes a first shielding portion 3411 and a second shielding portion 3413, which are sequentially connected and relatively fixed in the third direction z. In one possible implementation, the first shielding portion 3411 adopts a first shielding sheet 3412 with an integral structure. In one example, the first shielding sheet 3412 and the second end 322 (i.e., the second end 522) of the first signal transmission unit 320 are disposed opposite each other in the second direction y, and the first shielding sheet 3412 and the first signal transmission unit 320 can be fixed simultaneously by the insulating fixing seat 311 (i.e., the insulating fixing seat 511). It should be noted that the specific structure and fixing method of the first shielding sheet 3412 are not limited in the embodiments of this application.

[0194] like Figure 8b and Figure 8d As shown, in one possible implementation, the second shielding portion 3413 includes a plurality of second shielding plates 3414 arranged sequentially at intervals in the first direction x. One end of each second shielding plate 3414 is connected to the first shielding plate 3412, and the other end is elastically abutted against the second shielding member 441 in the corresponding second connector 400 (see...). Figure 10b ).

[0195] The connection method between the second shielding plate 3414 and the first shielding plate 3412 is not limited. In one possible implementation, such as... Figure 8d As shown, the second shielding plate 3414 and the first shielding plate 3412 are fixed together as a whole. That is, the first shielding component 341 formed by the first shielding portion 3411 and the second shielding portion 3413 is an integral structure, which is simple to process and facilitates the uniformity of the overall structure of the signal transmission unit, thus improving stability. In other possible implementations, the first shielding component 341 is a split structure. For example, the second shielding plate 3414 can be installed and fixed onto the first shielding plate 3412 one by one by welding.

[0196] Those skilled in the art will understand that the specific structure and fixing method of the second shielding plate 3414 are not limited, thus allowing for flexible design and selection based on actual application. When multiple second shielding plates 3414 are used to elastically abut against the corresponding second shielding components, the stability of the structural fit is improved while ensuring signal return, making the connector more reliable. It should be noted that in other possible implementations, the second shielding portion 3413 includes one second shielding plate 3414, meaning the second shielding plate 3414 is an integral structure that can be fixed to the first shielding plate 3412. In this case, the first shielding component 341 can be an integral structure or a separate structure, and this application embodiment does not impose any limitations on this.

[0197] In one possible implementation, such as Figure 8d As shown, and in combination Figure 10b It can be understood that in the first connector 300, multiple second shielding plates 3414 can be arranged one-to-one with multiple first signal transmission sections 320. A gap S1 is formed between any two adjacent second shielding plates 3414, and the gap S1 is located between adjacent first signal transmission sections 320 in the first direction x. Alternatively, it can be understood that each first signal transmission section 320 is equipped with one second shielding plate 3414. The second shielding plates 3414 can be arranged according to the number of first signal transmission sections 320 in the first signal transmission module 310, and the gap S1 between adjacent second shielding plates 3414 makes it easier for the second shielding plates 3414 to undergo elastic deformation, allowing for better elastic contact with the corresponding position (i.e., the spring-loaded part 4411) on the second shielding member 441. This improves the reliability of the shielding structure connection in the connector module 200 and ensures the integrity and stability of signal transmission. Specifically, the gap S1 being located between adjacent first signal transmission sections 320 in the first direction x provides a better shielding effect compared to the gap S1 being located within the coverage area of ​​a single first signal transmission section 320.

[0198] It should be noted that the number of the second shielding sheet 3414 in this embodiment is not limited. In one possible implementation, such as Figure 8a and Figure 8d As shown, the first connector 300 will have an additional second shielding plate 3414 on each side of the first signal transmission module 310 to achieve a more complete shielding and grounding effect.

[0199] In one possible implementation, such as Figure 8dAs shown, a sub-shielding member 3415 (i.e., sub-shielding member 544) corresponding to a first signal transmission section 320 may be a second shielding plate 3414 corresponding to the first signal transmission section 320, and a portion of a first shielding plate 3412 connected to the second shielding plate 3414. Other possible structures of the first connector 300 will be described below.

[0200] like Figure 8a and Figure 8b As shown, and in combination Figure 3a and Figure 3b It is understood that, in one possible implementation, the end of the first shield 341 in the first connector 300 away from the second connector 400 may also be provided with a grounding pin 342. In one example, the grounding pin 342 is fixed to the end of the first shield 3412 away from the second shield 3414, so that the first shielding structure 340 in the first connector 300 can be electrically connected to the ground plane of the circuit board 130 (or can be understood as the single board 111 or the backplane 114) in the communication device 100, ensuring that the grounding signal can achieve signal return through the grounding connection part on the circuit board 130, the grounding pin 342 in the first connector 300, and the first shielding structure 340, thus ensuring the integrity of signal transmission. It should be noted that this application does not limit the fixing method and setting position of the grounding pin 342. In one possible implementation, the grounding pin 342 and the first shield 341 are an integral structure, and the grounding pin 342 and the first shield 341 are arranged perpendicularly to each other. In other possible implementations, the grounding pin 342 is fixed to the first shield 341 by a processing technology such as welding, and the grounding pin 342 and the first shield 341 may not be perpendicular to each other.

[0201] like Figure 8a and Figure 8b As shown, and in combination Figure 3a and Figure 3b It is understood that, in one possible implementation, the second end 322 of the first signal transmission unit 320 has a signal pin 3321 for transmitting signals. In one example, the signal pin 3321 can be electrically connected to the trace layer of the circuit board 130 in the communication device 100 to realize signal transmission. In one possible implementation, the first connector 300 is directly soldered to the circuit board 130 via the signal pin 3321, and this application embodiment does not limit this.

[0202] like Figure 8a and Figure 8dAs shown, in one possible implementation, additional shielding members 343 are provided on both sides of the second end portion 322 of the first signal transmission unit 320 in the first direction x, and the additional shielding members 343 are fixed to the first shielding member 341. The additional shielding members 343, located on both sides of the second end portion 322 of the first signal transmission unit 320, can specifically isolate crosstalk phenomena present at the locations where the second end portion 322 of each first signal transmission unit 320 is electrically connected to other devices (e.g., circuit board 130), thereby reducing crosstalk. In this case, two additional shielding members 343 are provided between the second ends portion 322 of adjacent first signal transmission units 320, resulting in better shielding for each first signal transmission unit 320 at its second end portion 322. It should be noted that the number of additional shielding members 343 is not limited in the embodiments of this application. In other possible implementations, an additional shielding member 343 can be provided between the second ends 322 of adjacent first signal transmission units 320. That is, adjacent first signal transmission units 320 can share an additional shielding member 343 to achieve the shielding effect. Specifically, the shielding effect of the additional shielding member is related to its thickness. Therefore, when a single additional shielding member is used for shielding, its thickness can be increased accordingly to ensure the shielding effect.

[0203] It should be noted that the method of fixing the additional shield 343 is not limited in the embodiments of this application. In one possible implementation, the two adjacent sides of the additional shield 343 are fixedly connected to the grounding pin 342 and the first shield 341, respectively.

[0204] Furthermore, the structure of the additional shielding member 343 is not limited. In one possible implementation, the additional shielding member 343 is a triangular metal shielding sheet. In other possible implementations, the additional shielding member 343 may also be a metal block structure, and this application embodiment does not limit this.

[0205] Those skilled in the art will understand that the fixing method between the additional shielding member 343 and the first shielding member 341 is not limited. In other possible implementations, the additional shielding member 343 can form an integral structure with the first shielding member 341. In one example, the additional shielding member 343 and the first shielding sheet 3412 are an integral structure. Those skilled in the art can make specific settings according to actual needs.

[0206] It should be noted that the extension path of the first signal transmission terminal 330 is not limited. For example... Figure 8cAs shown, in one possible implementation, the second end 332 (i.e., the second end 532) of the first signal transmission terminal 330 extends along a straight line parallel to the third direction z. The first shielding portion 3411 can be arranged parallel to the second end 332 of the first signal transmission terminal 330. The portion of the first signal transmission terminal 330 excluding its second end 332 can extend along a broken line, and this portion can be inclined in the third direction z. The second shielding portion 3413 can be arranged parallel or approximately parallel to the portion of the first signal transmission terminal 330 excluding its second end 332. This ensures that the distance between the first signal transmission terminal 330 and the first shielding member 341 remains as consistent as possible along the extension path of the first signal transmission terminal 330, which is beneficial for impedance matching and reducing crosstalk between signal transmission components. In other possible implementations, such as... Figure 8c As shown, the second shielding portion 3413 may not be parallel to the portion of the first signal transmission terminal 330 other than its second end 332. However, it is necessary to take into account signal crosstalk and make reasonable arrangements. This structure can better realize the insertion and removal between the first connector 300 and the second connector 400, reduce the spatial interference between the signal transmission terminal and the shielding, improve the reliability of the structure, and ensure the stability of signal transmission.

[0207] Furthermore, in one possible implementation, such as Figure 8c and Figure 8d As shown, and in combination Figure 10b It is understood that the first end 331 (i.e., the first end 531) of the first signal transmission terminal 330 in the first connector 300 may include a spring tab 3311. The first connector 300 can elastically abut against the corresponding second signal transmission terminal 430 in the second connector 400 via the spring tab 3311 of the first signal transmission terminal 330. This achieves electrical connection between the first connector 300 and the second connector 400 and also improves the contact reliability of the connectors during insertion. It should be noted that the shape of the spring tab 3311 along its length is not limited. In one possible implementation, the spring tab 3311 can be V-shaped. In other possible implementations, the spring tab 3311 can be a semi-enclosed "C" shaped structure.

[0208] In other possible implementations, the signal transmission terminals in the first connector 300 and the second connector 400 can also be electrically connected by means of crimping or other methods, and this application does not limit this.

[0209] Furthermore, to better secure the first signal transmission terminal 330 in the first connector 300, a snap-fit ​​portion 3111 can be provided on the insulating mounting base 311, and correspondingly, a snap-fit ​​portion 333 can be provided on the first signal transmission terminal 330. In one possible implementation, such as... Figure 8d As shown, the latching portion 333 is formed by recessing the first signal transmission terminal 330 portion toward the adjacent first signal transmission terminal 330. Through the latching action between the latching portion 3111 and the latching portion 333, the first signal transmission terminal 330 is better limited and fixed, which can reduce the possible damage to it during the insertion and removal process, improve the structural stability of the first signal transmission terminal 330 when transmitting signals, and ensure the signal transmission rate and quality of the first connector 300.

[0210] The above mainly introduces the specific structure of the first connector 300. The following text will elaborate on the specific structure of the second connector 400.

[0211] Please see Figures 9-10c , Figure 9 This is an exploded view of the signal transmission module of the second connector in the connector module of this application embodiment. Figure 10a This is a three-dimensional structural diagram of the mating of the first connector and the second connector in the connector module of this application embodiment. Figure 10b for Figure 10a A cross-sectional view along line AA, in which the cables have been removed. Figure 10c This is a schematic diagram of the signal transmission module in the first connector and the second connector of the connector module in the embodiment of this application.

[0212] like Figure 9 As shown, and in combination Figures 5a to 5c It should be understood that the second connector 400 can adopt the specific structure of the connector 500 described above. Accordingly, the second connector 400 includes at least one second signal transmission module 410 (i.e., signal transmission module 510), each second signal transmission module 410 includes a plurality of second signal transmission parts 420 (i.e., signal transmission parts 520), and each second signal transmission part 420 includes two second signal transmission terminals 430 (i.e., signal transmission terminals 530) spaced apart in the first direction x. Those skilled in the art will understand that, in use, the second connector 400 can be designed according to specific requirements, and the embodiments of this application are not limited herein.

[0213] The second signal transmission module 410 includes a second shielding structure 440 (i.e., shielding structure 540), and the second shielding structure 440 includes a second shielding element 441 (i.e., shielding element 541). For example... Figure 9 and Figure 10bAs shown, the surface of the second shield 441 facing the second signal transmission section 420 is provided with a plurality of protruding spring-loaded portions 4411 for elastically abutting against the corresponding first shield 341 in the first connector 300 to achieve signal return. The plurality of spring-loaded portions 4411 are arranged at intervals in the first direction x. It should be noted that the number of spring-loaded portions 4411 is not limited in this embodiment.

[0214] Furthermore, the specific structure and formation method of the spring-loaded portion 4411 are not limited in the embodiments of this application. For example... Figure 9 As shown, in one possible implementation, the spring-loaded portion 4411 is configured as an elastic arm, which is fixed to the second shield 441. For example, the elastic arm can be fixed to the second shield 441 by welding. In other possible implementations, the connection between the spring-loaded portion 4411 and the second shield 441 can also be an integral structure, and this application embodiment does not limit this.

[0215] It should be noted that the specific form of the second shielding member 441 is not limited in the embodiments of this application. In one possible implementation, the second shielding member 441 is a one-piece structure; in other possible implementations, the second shielding member 441 is a split structure. The second shielding member 441 can be designed as a two-piece, three-piece, etc. Figure 9 As shown, the thickness of the portion of the second shield 441 located in the second signal transmission section 420 is increased, which can better support the second signal transmission terminal 430 and facilitate the fixing of the insulating fixing seat 411 (i.e., the insulating fixing seat 511), thereby improving the stability of signal transmission in the second connector 400.

[0216] In one possible implementation, additional shielding members 442 are provided on both sides of the second end portion 422 of the second signal transmission unit 420 in the first direction x, and the additional shielding members 442 are fixed to the second shielding member 441. The additional shielding members 442 are located at the end of the second shielding member 441 near the second end portion 422 of the second signal transmission unit 420, and are used to specifically isolate crosstalk phenomena that exist at the locations where the second end portion 422 of each second signal transmission unit 420 is electrically connected to other devices (e.g., cables), thereby reducing crosstalk. Figure 9 and Figure 10c As shown, in one example, an additional shield 442 can be provided between adjacent second signal transmission units 420. In this case, adjacent second signal transmission units 420 share an additional shield 442, which can reduce the degree of crosstalk, realize signal return, and ensure the integrity of signal transmission.

[0217] like Figures 10a-10c As shown, and in combination Figure 3a and Figure 3bIt is understood that the second connector 400 is configured to correspond to each signal transmission section of the cable 122 in the communication device 100, and the shielding layer of each cable 122 contacts the second shielding structure 440 of the second connector 400 to achieve grounding signal electrical connection. The signal core of each cable 122 is electrically connected to the second signal transmission terminal 430 of the corresponding second signal transmission section 420 in the second connector 400.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
