[0002] With the rapid increase in demand for high-bandwidth transmission and high-performance computing, the requirements for signal rate and bandwidth between boards (such as service boards and line cards) in high-speed system architecture are becoming increasingly higher.

[0003] Single boards using PCB (Printed Circuit Board) technology have high losses and poor flexibility.

[0004] In an orthogonal high-speed system architecture, the tolerance and deformation of the boards will inevitably accumulate between the connections between the boards (such as connectors), causing the connectors to operate in an incompletely mated state, resulting in a decrease in connector performance and affecting signal transmission.

[0038] To enable those skilled in the art to better understand the technical solutions of the embodiments of the present disclosure, the cable connection structure, single board assembly, and single board assembly connection structure provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0039] The embodiments of the present disclosure will be described more fully below with reference to the accompanying drawings, but the illustrated embodiments may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully enable those skilled in the art to understand the scope of this disclosure.

[0040] The accompanying drawings of the embodiments of the present disclosure are used to provide a further understanding of the embodiments of the present disclosure and constitute a part of the specification. Together with the embodiments of the present disclosure, they are used to explain the present disclosure and do not constitute a limitation of the present disclosure. By describing the detailed exemplary embodiments with reference to the accompanying drawings, the above and other features and advantages will become more apparent to those skilled in the art.

[0041] The embodiments of the present disclosure may be described with reference to plan views and / or cross-sectional views by way of ideal schematic views of the present disclosure. Therefore, the exemplary illustrations may be modified according to manufacturing techniques and / or tolerances.

[0042] In the absence of conflict, the various embodiments of the present disclosure and the various features therein may be combined with each other.

[0043] The terms used in this disclosure are only used to describe specific embodiments and are not intended to limit the disclosure. As used in this disclosure, the term "and / or" includes any and all combinations of one or more related enumerated items. As used in this disclosure, the singular forms "a" and "the" are also intended to include plural forms, unless the context clearly indicates otherwise. As used in this disclosure, the terms "comprising" and "made of" specify the presence of the features, wholes, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or groups thereof.

[0044] Unless otherwise defined, all terms (including technical and scientific terms) used in this disclosure have the same meanings as those commonly understood by those skilled in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this disclosure, and will not be interpreted as having an idealized or overly formal meaning unless expressly defined in this disclosure.

[0045] The embodiments of the present disclosure are not limited to the embodiments shown in the drawings, but include modifications of the configurations formed based on the manufacturing process. Therefore, the regions illustrated in the drawings are schematic in nature, and the shapes of the regions shown in the drawings illustrate the specific shapes of the regions of the elements, but are not intended to be limiting.

[0046] High-speed system architectures use printed circuit boards (PCBs) as a signal transmission medium. As signal transmission rates and bandwidths increase, insertion loss also increases. To reduce insertion loss, some technologies use cables instead of printed circuit boards as a signal transmission medium.

[0047] On the one hand, compared with PCB, the insertion loss per unit length of cable is lower; on the other hand, since PCB is used as the medium for signal transmission, signal transmission needs to rely on PCB traces. Compared with PCB traces that use crimping to transmit signals, cables have greater flexibility.

[0048] The use of cables effectively reduces insertion loss during signal transmission. However, in actual high-speed system architectures, especially orthogonal high-speed system architectures, the accumulation of tolerances and structural deformations (such as single-board deformation) causes the connecting devices (such as connectors) between single boards to be unable to operate in a fully mated state, that is, in a non-fully mated state (de-mate). Using cables instead of PCBs as a signal transmission medium cannot solve this problem.

[0049] When a connector operates in a partially mated state (de-mate), its impedance characteristics and insertion loss will degrade significantly compared to when it operates in a fully mated state. This degradation is particularly pronounced when the signal transmission bandwidth reaches a certain threshold. The expected high-speed serial single-channel signal rate (SerDes rate) is 112Gbps or even higher, with an operating frequency of 28GHz (fluctuating between 0 and 42GHz), reaching the threshold where connector performance deteriorates significantly. Therefore, the performance degradation caused by the partially mated connector has a non-negligible impact on signal transmission.

[0050] When the connector operates in a non-fully mated state, not only will the performance of the connector be reduced, but in order to ensure mechanical contact when the connector operates in a non-fully mated state, the connector terminals need to be designed with a longer friction distance. In order to ensure the performance and robustness of the connector under a longer friction distance, the design complexity and design cost of the connector are further greatly increased.

[0051] In some related technologies, connector upgrades with higher design complexity are used to ensure that the connector has better performance even when working in a non-fully mated state. However, the iteration cycle of connectors with higher design complexity is long, and especially the challenge of making them compatible with existing products is huge.

[0052] Other related technologies limit board deformation and tolerances in high-speed system architectures to ensure connectors operate in a fully mated state, thereby guaranteeing connector performance. However, even with current structural designs that employ advanced panel wrenches and screw locks to minimize tolerance accumulation on the board rather than at board connections (e.g., connectors), the large size of the chassis and boards, structural deformation, and other factors can still cause connectors to operate in a non-fully mated state, resulting in a certain de-mate distance. Even a de-mate distance of 1.0 mm can significantly degrade connector performance.

[0053] First, refer to Figures 1 to 8 , an embodiment of the present disclosure provides a cable connection structure, which includes:

[0054] A carrier 101 having at least one cable connector 104 disposed thereon, each cable connector 104 having a first port connected to the cable 12 and a second port electrically connected to the first port;

[0055] The sliding structure 102 is connected to the carrier 101, and the carrier 101 is used to connect to the single board 11 through the sliding structure 102. The carrier 101 can make the single board 11 connected to it slide in a first direction, and the first direction is the direction of approaching or moving away from the second port of the cable connector 104 on the carrier 101.

[0056] The cable connection structure of the embodiment of the present disclosure specifically includes a carrier 101 , at least one cable connector 104 fixedly disposed on the carrier 101 , and a sliding structure 102 connected to the carrier 101 .

[0057] The cable connector 104 is fixed to the carrier 101. For example, the cable connector 104 can be fixed to the carrier 101 by crimping (of course, the crimping pins do not have a signal transmission function and only serve a fixing purpose). Of course, the cable connector 104 can also be fixed to the carrier 101 by other means (such as welding, bonding, clamping, etc.).

[0058] Cable connector 104 has a first port and a second port. The first port is used to connect to cable 12, and the second port is electrically connected to the first port and can also be connected to other ports. In other words, a signal can be transmitted through cable 12 to the first port connected to cable 12, and then transmitted to other ports connected to the second port connected to the first port.

[0059] The sliding structure 102 connected to the carrier 101 can specifically be a slide rail. The carrier 101 can be connected to the single board 11 via the sliding structure 102. The single board 11 connected to the carrier 101 can slide in a first direction via the sliding structure 102, which is a direction toward or away from the second port of the cable connector 104. The sliding is relative. If the single board 11 connected to the sliding structure 102 is fixed and cannot slide, the carrier 101 can slide relative to the single board 11 along the first direction.

[0060] The cable connection structure of the embodiment of the present disclosure fixes the cable connector 104 on a carrier 101 that can slide relative to the single board 11, so that the position of the cable connector 104 relative to the single board 11 can change in a certain direction. When the single board 11 is deformed or has tolerances that cannot meet the requirements of the cable connector 104 in the required position, that is, the cable connector 104 cannot work in a fully mated state, the relative position of the cable connector 104 and the single board 11 is changed through the sliding structure 102, so that the cable connector 104 is still in a position where it can be fully mated, thereby ensuring that the cable connector 104 can still work in a fully mated state, avoiding the situation where the single board 11 is deformed or the tolerances accumulate in the connector, causing the connector to work in a non-fully mated state, thereby causing the connector performance to decline and affecting signal transmission.

[0061] In some embodiments, reference Figures 1 to 8 The carrier 101 is plate-shaped and is provided with a plurality of cable connectors 104 . The plurality of cable connectors 104 are sequentially arranged along a direction perpendicular to the first direction.

[0062] The carrier 101 of the cable connection structure of the embodiment of the present disclosure can be in the form of a plate, specifically a single board 11, and can be smaller than a typical single board 11. A plurality of cable connectors 104 are fixed to the carrier 101. The plurality of cable connectors 104 are arranged in a direction perpendicular to the first direction, that is, the arrangement direction of the cable connectors 104 is perpendicular to the sliding direction of the single board 11.

[0063] Since the carrier 101 is connected to the single board 11 through the sliding structure 102, the length of the carrier 101 in the first direction perpendicular to the first direction is fixed. Setting the cable connector 104 in a direction perpendicular to the first direction can ensure that the length of the carrier 101 in the first direction perpendicular to the first direction is fully utilized (if the cable connector 104 is set in a direction parallel to the first direction, only the length of the cable connector 104 of the carrier 101 in the first direction perpendicular to the first direction is utilized), thereby reducing the size of the carrier 101.

[0064] In some embodiments, the cable connection structure further includes a sliding locking device 103 for fixing the sliding structure 102 relative to the supporting member 101 .

[0065] The cable connection structure of the disclosed embodiment further includes a sliding locking device 103, which can secure the sliding structure 102 relative to the carrier 101. Essentially, the sliding locking device 103 establishes a rigid structural relationship between the single board 11 connected to the sliding structure 102 and the carrier 101, fixing their relative positions. That is, when the sliding locking device 103 is locked, the single board 11 connected to the sliding structure 102 is fixed and cannot slide, and the carrier 101 is also fixed and cannot slide. When the sliding locking device 103 is unlocked, the single board 11 connected to the sliding structure 102 can slide relative to the carrier 101 (either the single board 11 connected to the sliding structure 102 slides along the sliding structure 102, or the carrier 101 slides along the sliding structure 102, or both can slide along the sliding structure 102).

[0066] Through the sliding locking device 103, when the connection between the single board 11 connected to the sliding structure 102 and the carrier 101 has been set and no relative position change is desired, the relative position of the single board 11 connected to the sliding structure 102 and the carrier 101 can be fixed to facilitate their installation or movement as a whole.

[0067] Secondly, refer to Figure 2 , an embodiment of the present disclosure provides a single board assembly 1, which includes: a single board 11, any one of the above-mentioned cable connection structures, the single board 11 is slidably connected to the bearing member 101 through a sliding structure 102;

[0068] The board 11 includes at least one cable interface 111;

[0069] The board assembly 1 further includes a cable 12 connected between the cable interface 111 and the first port of the cable connector 104 .

[0070] The single-board assembly 1 of the disclosed embodiment specifically includes any of the aforementioned cable connection structures, and a single-board 11 slidably connected to the cable connection structure's support member 101 via the cable connection structure's sliding structure 102. Single-board 11 is provided with at least one cable interface 111 (which may also be a cable connector). Cable interface 111 can be located anywhere on single-board 11 (e.g., on the board itself or on its edge). Cable interface 111 on single-board 11 is connected to the first port of the cable connector 104 of the cable connection structure via a cable 12.

[0071] Specifically, the single board 11 may be a service single board, a switching network board, etc. The cable interface 111 on the single board 11 and the cable connector 104 of the cable connection structure may have a one-to-one relationship, i.e., each cable interface 111 on the single board 11 is connected to the first port of a different cable connector 104 of the cable connection structure; the cable interface 111 on the single board 11 and the cable connector 104 of the cable connection structure may have a one-to-many relationship, i.e., each cable interface 111 on the single board 11 is connected to the first ports of multiple different cable connectors 104 of the cable connection structure; the cable interface 111 on the single board 11 and the cable connector 104 of the cable connection structure may have a many-to-one relationship, i.e., the first port of each cable connector 104 of the cable connection structure is connected to multiple different cable interfaces 111 on the single board 11.

[0072] The cable 12 is more flexible than the PCB. The cable connector 104 is connected to the board 11 through the cable 12. Even if the relative positions of the cable connector 104 and the board 11 change, the connection through the cable 12 will not affect signal transmission.

[0073] The single board assembly 1 of the disclosed embodiment utilizes the flexibility of the cable 12 and fixes the cable connector 104 on a carrier 101 that can slide relative to the single board 11, so that the position of the cable connector 104 relative to the single board 11 can change in a certain direction. When the single board 11 is deformed or has tolerances that cannot satisfy the cable connector 104 in the required position, that is, the cable connector 104 cannot work in a fully mated state, the sliding structure 102 is used to change the relative position of the cable connector 104 and the single board 11, so that the cable connector 104 is still in a position where it can be fully mated, to ensure that the cable connector 104 can still work in a fully mated state, thereby avoiding the situation where the single board 11 is deformed or the tolerances accumulate in the connector, causing the connector to work in a non-fully mated state, thereby causing the connector performance to decline and affecting the signal transmission.

[0074] Thirdly, refer to Figures 1 to 8 , an embodiment of the present disclosure provides a single board component connection structure, which includes:

[0075] A first single board component group, comprising at least one single board component 1 of any one of the above;

[0076] A second single board component group, comprising at least one single board component 2 of any one of the above;

[0077] The second port of at least one cable connector 104 in each single board assembly 1 in the first single board assembly group is electrically connected to the second port of the cable connector 204 of one single board assembly 2 in the second single board assembly group.

[0078] In order to distinguish the first single board component group from the second single board component group, Figures 1 to 8 The board components of the second board component group are labeled 2. Each board component 2 includes a carrier 201, a sliding structure 202, and a cable connector 204 located on the carrier 201. In some embodiments, the board components 2 also include a sliding locking structure 203. However, the structures of the board components 2 and 1 are essentially the same, and both are board components according to the present disclosure.

[0079] The single-board component connection structure of the embodiment of the present disclosure specifically includes a first single-board component group and a second single-board component group, each of which includes at least one of the above-mentioned single-board components 1 or 2. Each single-board component 1 of the first single-board component group has at least one second port of a cable connector 104 electrically connected to the second port of a cable connector 204 of one of the single-board components 2 of the second single-board component group.

[0080] The single-board component connection structure of the disclosed embodiment fixes the cable connector 104 on a carrier 101 that can slide relative to the single board 11, so that the position of the cable connector 104 relative to the single board 11 can change in a certain direction. When the single board 11 is deformed or has tolerances that cannot meet the requirements of the cable connector 104 in the required position, that is, the cable connector 104 cannot work in a fully mated state, the sliding structure 102 is used to change the relative position of the cable connector 104 and the single board 11, so that the cable connector 104 is still in a position where it can be fully mated, thereby ensuring that the cable connector 104 can still work in a fully mated state, thereby avoiding the situation where the single board 11 is deformed or the tolerances accumulate in the connector, causing the connector to work in a non-fully mated state, thereby causing the connector performance to decline and affecting signal transmission.

[0081] In some embodiments, reference Figures 1 to 4 The second port of at least one cable connector 104 in each single board component 1 in the first single board component group is connected to the second port of the cable connector 204 of one single board component 2 in the second single board component group.

[0082] In the single-board component connection structure of the embodiment of the present disclosure, each single-board component 1 of the first single-board component group has at least one second port of a cable connector 104 connected to the second port of a cable connector 204 of one of the single-board components 2 of the second single-board component group. The connection here refers to the connection of different groups of cable connectors 104 or 204 in a fully mated state.

[0083] That is, the second port of at least one cable connector 104 in each single board component 1 in the first single board component group is directly connected to the second port of the cable connector 204 of a single board component 2 in the second single board component group, rather than being electrically connected through other ports or cables 12.

[0084] In some embodiments, reference Figure 2 and Figure 3 The first single board assembly group includes a plurality of any of the above single board assemblies 1, wherein the single boards 11 of each single board assembly 1 are parallel to each other;

[0085] The second single board assembly group includes a plurality of any of the above-mentioned single board assemblies 2, wherein the single boards 21 of each single board assembly 2 are parallel to each other, and the angle between them and the single boards 11 in the first single board assembly group is greater than 0 degree and less than or equal to 90 degrees.

[0086] In the single board component connection structure of the embodiment of the present disclosure, the first single board component group includes a plurality of single board components 1 , and the second single board component group includes a plurality of single board components 2 .

[0087] Specifically, the single board 11 or 21 in the first single board component group and the second single board component group can be a service single board or a switching network board, etc., which are usually plate-shaped. The single boards 11 of each single board component 1 in the first single board component group are parallel to each other, and the single boards 21 of each single board component 2 in the second single board component group are parallel to each other. There is a specific angle (i.e., relative inclination) between the single boards of the single board components of different groups (i.e., single board 11 and single board 21).

[0088] The boards of different groups of board assemblies are relatively tilted, and the boards of each board assembly can intersect with the boards of multiple board assemblies in another board assembly group to achieve more connections. Further, the angle between the board 11 and the board 21 is greater than 60 degrees and less than or equal to 90 degrees. Further, as Figure 2 As shown, the angle between the single board 21 and the single board 11 is equal to 90 degrees, and the first single board component group and the second single board component group form an orthogonal high-speed system architecture.

[0089] Through the first single-board component group and the second single-board component group of the embodiment of the present disclosure, it is possible to realize that the signal is transmitted from the cable interface 111 on the single board 11 of the first single-board component group through the cable 12 to the first port of the cable connector 104 of the cable connection structure in the single-board component 1 of the first single-board component group, and then through the second port of the cable connector 104 in the first single-board component group and the second port of the cable connector 204 in the second single-board component group, it reaches the first port of the cable connector 204 in the second single-board component group, and then through the cable 22 to the cable interface 211 on the single board 21 of the second single-board component group, thereby realizing the transmission of the signal from the single board 11 of the first single-board component group to the single board 21 of the second single-board component group. Of course, the signal can also be transmitted in the reverse direction, that is, from the single board 21 of the second single-board component group to the single board 11 of the first single-board component group.

[0090] In some embodiments, the single board assembly connection structure further includes a connection locking device 3 for locking the cable connector 104 of the first single board assembly group and the cable connector 204 of the second single board assembly 2 electrically connected thereto.

[0091] The single board assembly connection structure of the embodiment of the present disclosure further includes a connection locking device 3 for locking the cable connector 104 of the first single board assembly group and the cable connector 204 of the second single board assembly group.

[0092] When the second port of the cable connector 104 of the first single-board component group is connected to the second port of the cable connector 204 of the second single-board component group, that is, the cable connector 104 of the first single-board component group is fully matched with the cable connector 204 of the second single-board component group, the connection locking device 3 is locked to fix the connection state of the cable connector 104 of the first single-board component group and the cable connector 204 of the second single-board component group, so that the cable connector 104 of the first single-board component group and the cable connector 204 of the second single-board component group are always fully matched, ensuring that the cable connector 104 of the first single-board component group and the cable connector 204 of the second single-board component group work in a fully matched state.

[0093] In some embodiments, reference Figure 4 The single board component connection structure further includes a fixing frame 5 , and the first single board component group and the second single board component group are located on opposite sides of the fixing frame 5 .

[0094] The single-board component connection structure of the disclosed embodiment further includes a fixing frame 5, which can specifically be a system frame, with the first single-board component group and the second single-board component group located on either side thereof. The fixing frame 5 has a slot for inserting the single board 11 or the single board 21. When the single board 11 or the single board 21 is fully inserted into the slot, it can be assumed that the cable connector 104 or the cable connector 204 corresponding to the single board 11 or the single board 21 is also in the correct position. When the cable connector 204 connected to the cable connector 104 or 204 or the single board 21 or the single board 11 corresponding to the cable connector 104 or 204 is also fully inserted into the fixing frame 5, it indicates that the two cable connectors 104 and 204 are correctly connected and are in a fully mated state.

[0095] In some embodiments, the single board assembly 1 or 2 of the single board assembly connection structure of the embodiment of the present disclosure includes a sliding locking device, and the assembly process thereof may specifically be:

[0096] The sliding locking device 103 or 203 is locked, and the supporting member 101 or 201 of the cable connection structure and the single board 11 or 21 of the single board assembly 1 or 2 become a rigid structural relationship, and the relative position is fixed. The single board 11 or 21 of the single board assembly 1 or 2 with the relative position of the single board 11 or 21 and the supporting member 101 or 102 is inserted into the fixed frame 5 to facilitate the second port of the cable connector 104 or 204 thereon to be connected to the second port of the cable connector 204 or 104 of the corresponding group of single board assemblies 2 or 1.

[0097] When the single board components 1 and 2 of the first single board component group and the second single board component group are fully inserted into the fixed frame 5, that is, the cable connector 104 of the first single board component group is fully matched with the cable connector 204 of the second single board component group, the connection locking device 3 is locked to fix the connection state of the cable connector 104 of the first single board component group and the cable connector 204 of the second single board component group, and at the same time, the sliding locking devices 103 and 203 are unlocked so that the single boards 11 and 12 can slide along the sliding structures 102 and 202.

[0098] When there is deformation or tolerance of the single board 11 or 21, so that when the cable connector 104 of the first single board component group and the cable connector 204 of the second single board component group are working in a fully matched state, the single board 11 or 21 has not reached its predetermined position (such as the other side of the single board 11 or 21 cannot be fully connected with other components of the system), so that the system where the single board component connection structure is located cannot work normally, then the single board 11 or 21 is slid to make the single board 11 or 21 reach its predetermined position (that is, the cable connector 104 or 204 is stationary, the single board 11 or 21 can slide, and is not fully inserted into the fixed frame 5) to ensure that the system where the single board component connection structure is located can work normally. At the same time, the cable connector 104 of the first single board component group and the cable connector 204 of the second single board component group are also working in a fully matched state.

[0099] In some embodiments, the cable connection structure of the single board assembly connection structure further includes a sliding locking device 103 or 203;

[0100] Reference Figure 6 The single board component connection structure also includes a linkage structure 4, which is used to place the connection locking device 3 in a locked state and the sliding locking device in an unlocked state; or to place the connection locking device 3 in an unlocked state and the sliding locking device in a locked state.

[0101] The single board assembly connection structure of the embodiment of the present disclosure further includes a sliding locking device 103 or 203 , a connection locking device 3 and a linkage structure 4 .

[0102] When the sliding locking device 103 or 203 of the single board assembly 1 or 2 is in the locked state, the single board 11 or 21 of the single board assembly 1 or 2 and the carrier 101 or 201 form a rigid structural relationship and are fixed in relative position. When the sliding locking device 103 or 203 of the single board assembly 1 or 2 is in the unlocked state, the single board 11 or 12 of the single board assembly 1 or 2 can slide relative to the carrier 101 or 201 in the first direction.

[0103] When the connection locking device 3 is in the locked state, the second port of the cable connector 104 of the first single-board assembly group is connected to the second port of the cable connector 204 of the second single-board assembly group, that is, the cable connector 104 of the first single-board assembly group is fully mated with the cable connector 204 of the second single-board assembly group. When the connection locking device 3 is in the unlocked state, the positions of the second port of the cable connector 104 of the first single-board assembly group and the second port of the cable connector 204 of the second single-board assembly group can change relative to each other.

[0104] The linkage structure 4 links the sliding locking device 103 or 203 and the connecting locking device 3 to ensure that when the connecting locking device 3 is in the locked state, the sliding locking device is in the unlocked state; or when the connecting locking device 3 is in the unlocked state, the sliding locking device is in the locked state.

[0105] The linkage structure 4 enables linkage between the connection locking device 3 and the sliding locking device 103 or 203, preventing the connection locking device 3 and the sliding locking device 103 or 203 from being in the same state, which would cause the single-board assembly connection structure of the present embodiment to malfunction. If both the connection locking device 3 and the sliding locking device 103 or 203 are in the unlocked state, the carrier 101 or 201 may also slide when the single board 11 or 21 slides, resulting in the cable connector 104 of the first single-board assembly group and the cable connector 204 of the second single-board assembly group not being able to fully mate.

[0106] Of course, you can also refer to Figure 5If the single-board component connection structure does not include the linkage structure 4, the connection locking device 3 can be placed in a locked state and the sliding locking device can be placed in an unlocked state through manual control; or the connection locking device 3 can be placed in an unlocked state and the sliding locking device can be placed in a locked state.

[0107] In some embodiments, reference Figure 7 and Figure 8 , the plate assembly connection structure further includes a back plate 6;

[0108] The carrier 101 or 201 is connected to the back plate 6;

[0109] The backplane 6 has a third port, which is connected to the second port, and the third port connected to the second port of the single board component 1 in the first single board component group is connected to another third port through a connecting circuit, and the other third port is connected to the second port of the single board component 2 in the second single board component group.

[0110] Reference Figure 7 The carrier 101 or 201 is connected to the backplane 6. The second port of the cable connector 104 of each single board assembly 1 in the first single board assembly group can also be connected to the backplane connector on the backplane 6. That is, the second port of the cable connector 104 and the backplane connector are in a fully mated state. The second port of the cable connector 204 of each single board assembly 2 in the second single board assembly group is also connected to the other port of the backplane connector, and is also in a fully mated state.

[0111] There are multiple backplane connectors on the backplane 6. The cable connector 104 in the first single-board component group and the cable connector 204 in the second single-board component group that connect different ports of the same backplane connector are electrically connected through the backplane connector. Since the cable connector 104 or 204 of each single-board component 1 or 2 is in a fully mated state with the backplane connector, the cable connector 104 in the first single-board component group and the cable connector 204 in the second single-board component group are naturally in a fully mated state.

[0112] Of course, refer to Figure 8 The first single-board component group and the second single-board component group can be located on the same side of the backplane 6. At this time, different backplane connectors on the backplane 6 are electrically connected, and the cable connector 104 in the first single-board component group that connects the two electrically connected backplane connectors and the cable connector 204 in the second single-board component group are also connected through these two backplane connectors.

[0113] In the actual structure, the second single-board component group can also be replaced with a traditional PCB crimping connector, that is, the second port of the cable connector 104 of the single-board component 1 in the first single-board component group is connected to the PCB crimping connector through the backplane connector to realize signal transmission.
