[0003] In related technologies, single boards may be equipped with connectors, and two adjacent single boards can be interconnected by snapping the connectors together. However, when a single board malfunctions and needs to be replaced, the tight structure of the connector makes the disassembly and installation process extremely cumbersome, not only consuming a lot of time, but also potentially damaging the single board due to improper operation.

Detailed Implementation

[0045] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0046] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0047] This application provides an interconnection device, a single-board assembly, and a complete system. The interconnection device, single-board assembly, and complete system are described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features in the following embodiments and implementations can be combined with each other.

[0048] Please refer to Figure 1 This application provides a single-board assembly, which includes an interconnection device and two single boards 10. The interconnection device is used to connect the two single boards 10.

[0049] The single board 10 can take various forms, such as a system motherboard, a power management board, or a network data exchange board. For example, the single board 10 can be a GPU (Graphics Processing Unit) board or a CPU (Central Processing Unit) board, but it is not limited to these.

[0050] Each board 10 includes a main body 11 and a connecting part 12 disposed on the main body 11. The connecting part 12 may be a solder pad or a communication interface soldered on the main body 11, or a connector fixed on the main body 11, but is not limited to these.

[0051] The interconnection device includes a connection structure and a movable structure. The connection structure includes a connection component 20, which includes a cable 22 and two contact connectors 21. The cable 22 connects the two contact connectors 21, meaning the two contact connectors 21 can establish a connection through the cable 22. The two contact connectors 21 are used for one-to-one connection with two single boards 10. Specifically, the two contact connectors 21 are used for one-to-one connection with the connection parts 12 on the two single boards 10.

[0052] The aforementioned contact connector 21 is a device for realizing electrical connection. It can establish a connection by contacting the connection part 12 on the single board 10, thereby transmitting current or signal. It can disconnect the connection by separating from the connection part 12 on the single board 10. The contact connector 21 can be a pin-shaped contact connector or a sheet-shaped wire contact connector, but is not limited to these.

[0053] The connecting assembly 20 has a first position and a second position. In the first position, the two contact connectors 21 are connected one-to-one with the connecting portions 12 of the two single boards 10; that is, one contact connector 21 is connected to the connecting portion 12 of one single board 10, and the other contact connector 21 is connected to the connecting portion 12 of the other single board 10. The two contact connectors 21 are also connected by a cable 22, thus establishing a connection between the two single boards 10 through the connecting assembly 20. In the second position, the contact connectors 21 are separated from the corresponding connecting portions 12 on the single board 10, thereby disconnecting the two single boards 10. It should be noted that the second position refers to a certain gap between the contact connectors 21 and the corresponding connecting portions 12. Due to this gap, the contact connectors 21 and the corresponding connecting portions 12 cannot establish a connection. This gap can be in any direction, as long as it allows the connectors 21 to separate from the corresponding connecting portions 12; therefore, no specific limitation is imposed.

[0054] The movable structure connects two contact connectors 21, which are used to drive the connection component 20 to switch between the first position and the second position.

[0055] By adopting the above technical solution, the connecting component 20 includes a cable 22 and two contact connectors 21. It establishes and disconnects the connection by contacting the connecting portion 12 on the single board 10, forming a relatively portable contact connection method. Compared to the tight connector snap-fit ​​structure in related technologies, the contact connection method of this solution makes it easier to establish and disconnect the connection with the single board 10 when it needs to be replaced or repaired, simplifying the disassembly and installation process. The movable structure connecting the two contact connectors 21 allows the connecting component 20 to switch between a first position (contact connector 21 connected to the connecting portion 12 of the single board 10) and a second position (contact connector 21 separated from the connecting portion 12 of the single board 10). This allows for convenient and quick connection and disconnection of the single board 10 and the connecting component 20, further improving the convenience of replacing the single board 10 and avoiding damage to other single boards 10 or connectors that may be caused by cumbersome operations.

[0056] Furthermore, it's easy to understand that in traditional connection methods using a backplane or panel, signals need to pass through the wiring within the board and the backplane or panel, increasing the signal transmission path. In this application, however, the connection component can directly and precisely connect the connection points on two boards 10. This achieves accurate interconnection while reducing the signal transmission path, improving the reliability of the interconnection between the two boards 10, and reducing the cost incurred due to the need for excessive driving components caused by long paths.

[0057] In one embodiment, the movable structure includes a rotating component 30 and a moving component 40. The moving component 40 includes two moving parts 41, both of which are connected to the rotating component 30, and each of the two moving parts 41 is connected to one of the two contact connectors 21. When the rotating component 30 rotates, it can drive the two moving parts 41 to move, thereby moving the two contact connectors 21 and causing the connecting component 20 to switch between a first position and a second position.

[0058] The contact connector 21 is moved by rotating the rotating component 30, thereby controlling the switching of the connection component 20 between the first and second positions. The rotation operation is relatively simple and intuitive, requiring no complicated operating skills or tools. Operators can easily complete the connection and disconnection operations between the board 10 and the connection component 20, improving work efficiency.

[0059] It should be noted that the rotation direction of the aforementioned rotating component 30 may include a first rotation direction and a second rotation direction, wherein the first rotation direction is opposite to the second rotation direction. When the rotating component 30 rotates along the first rotation direction, the connecting component 20 can switch from the second position to the first position; when the rotating component 30 rotates along the second rotation direction, the connecting component 20 can switch from the first position to the second position. The first and second rotation directions can be freely set, and this application does not impose specific limitations on them.

[0060] The aforementioned rotating assembly 30 and moving part 41 can be coupled in, but are not limited to, gear and rack, crank connecting rod and slider, or lead screw and nut.

[0061] For example, the rotating assembly 30 includes a lead screw, which is a rod-shaped component with external threads. Each moving part 41 includes a nut with internal threads that mate with the lead screw, and the nut is fitted onto the lead screw. When the lead screw rotates in a first rotation direction, due to the threaded engagement between the nut and the lead screw, the rotation of the lead screw causes the nut to move linearly along the lead screw. The nut drives the contact connector 21 connected to it to move towards the connection portion 12 of the single board 10, thereby connecting the contact connector 21 to the corresponding connection portion 12. When the lead screw rotates in a second rotation direction, the lead screw rotates in the opposite direction, and the nut moves linearly in the opposite direction along the lead screw. The nut drives the contact connector 21 connected to it to move away from the connection portion 12 of the single board 10, thereby causing the contact connector 21 to separate from the corresponding connection portion 12. In this embodiment, there can be one lead screw, with two nuts fitted onto opposite ends of the lead screw; or, there can be two lead screws, with two lead screws corresponding to two nuts, each nut fitted onto the corresponding lead screw.

[0062] Alternatively, the rotating assembly 30 includes two cranks, each moving part 41 including a slider constrained on a specific track, which may be formed in the cabinet 50 of the entire system, but is not limited thereto. Each crank is hinged to the slider via a connecting rod. When the crank rotates in the first rotation direction, the circular motion of the crank is transmitted to the slider via the connecting rod. Because the slider is constrained by the track, the slider can convert the circular motion of the crank into linear motion, moving towards the connection part 12 of the single board 10, thereby driving the contact connector 21 to move towards the connection part 12 of the single board 10, thus connecting the contact connector 21 to the corresponding connection part 12. When the crank rotates in the second rotation direction, the crank makes a reverse circular motion, and again through the transmission of the connecting rod, the slider moves linearly along the track away from the connection part 12 of the single board 10, thereby causing the contact connector 21 to separate from the corresponding connection part 12.

[0063] The rotating assembly 30 may include one or two rotating parts 31, which will be described in detail below.

[0064] In one embodiment, the rotating assembly 30 includes a rotating member 31, which is connected to two moving members 41 respectively; when the rotating member 31 rotates, the rotating member 31 can drive the two moving members 41 to move.

[0065] In this way, one rotating component 31 can drive two moving components 41 to move. The overall structure is relatively simple, reducing the number of parts and occupying less space. This is conducive to reasonable layout in single-board components and improves space utilization.

[0066] In one example, the rotating component 31 includes a lead screw with a first external thread and a second external thread, the first and second external threads being in opposite directions. Each moving component 41 includes a nut, one of which is fitted onto the first external thread and the other onto the second external thread. When the lead screw rotates, it can move both nuts.

[0067] Furthermore, within the single-board assembly, the connecting portions 12 of the two single boards 10 are disposed facing each other along a first direction; the first direction is parallel to the thickness direction of the single board 10. However, this is not a limitation; for example, in other embodiments, the first direction may also be perpendicular to the thickness direction of the single board 10.

[0068] The first direction includes a first sub-direction and a second sub-direction pointing in opposite directions. When the rotating member 31 rotates, each moving member 41 drives the corresponding contact connector 21 to move along the first sub-direction or the second sub-direction, so as to drive the connection assembly 20 to switch between the first position and the second position.

[0069] It should be noted that, as Figure 1 As shown, the first direction can be referenced to the X direction, the first sub-direction can be referenced to the X1 direction, and the second sub-direction can be referenced to the X2 direction.

[0070] Specifically, when the rotating member 31 rotates along the first rotation direction, one of the two moving members 41 moves along the first sub-direction, and the corresponding contact connector 21 moves along the first sub-direction; the other moving member 41 moves along the second sub-direction, and the corresponding contact connector 21 moves along the second sub-direction. When the rotating member 31 rotates along the second rotation direction, the aforementioned moving member 41 moves along the second sub-direction, and the aforementioned moving member 41 moves along the first sub-direction. In other words, when the rotating member 31 rotates along the second rotation direction, the moving member 41 that originally moved along the first sub-direction will change to move along the second sub-direction, and the other moving member 41 that originally moved along the second sub-direction will move along the first sub-direction.

[0071] The aforementioned rotating component 31 may include a gear, and the moving component 41 may include a rack, with the gear meshing with the racks on the two moving components 41 respectively; alternatively, the aforementioned rotating component 31 may include a lead screw, and the moving component 41 may include a nut, the lead screw having two oppositely oriented first external threads, and one of the two nuts being fitted onto the first external thread, and the other nut being fitted onto the first external thread. However, these are not limited to these embodiments.

[0072] In one specific embodiment, both the rotating member 31 and the moving member 41 are rod-shaped. The rotating member 31 is provided with a gear portion 311, and the moving member 41 is provided with a rack portion. The two opposite ends of the gear portion 311 respectively mesh with the rack portions on the two moving members 41. That is, one end of the gear portion 311 meshes with the rack portion of one moving member 41, and the other end of the gear portion 311 meshes with the rack portion of the other moving member 41.

[0073] The engagement between the gear section 311 and the rack section is relatively smooth, which can reduce vibration and impact during transmission and help protect the contact connector 21 of the single board 10 and the interconnection device from damage caused by vibration and impact.

[0074] Among them, the rotating component 31 can be driven by a variety of methods, such as manual, electric, or pneumatic, which makes it easier to implement in production.

[0075] For example, when manually driven, the end of the rotating part 31 can be provided with a handle 312, and the operator can rotate the rotating part 31 by using the handle 312; when electrically driven, a motor can be used to connect the rotating part 31, and the movement of the moving part 41 can be controlled by controlling the forward and reverse rotation and the speed of the motor.

[0076] Furthermore, the axial dimension of the gear portion 311 is greater than the width of the rack portion. This larger axial dimension of the gear portion 311 can compensate for axial deviations that may occur during installation or use. Even if there is slight axial misalignment between the gear and rack, a good meshing state can still be ensured because the axial dimension of the gear portion 311 is greater than the width of the rack portion. Moreover, since one gear portion 311 needs to mesh with two rack portions simultaneously, the larger axial dimension of the gear portion 311 facilitates meshing with the two rack portions.

[0077] Furthermore, there are multiple moving components 40 and multiple connecting components 20. The two moving parts 41 of each moving component 40 are connected one-to-one with the two contact connectors 21 of each connecting component 20. Each board 10 includes multiple connecting parts 12. In two boards 10, the multiple connecting parts 12 of one board 10 correspond one-to-one with the multiple connecting parts 12 of the other board 10. The connecting parts 12 of one board 10 and the corresponding connecting parts 12 of the other board 10 are connected by a connecting component 20. That is, a connecting component 20 connects the two corresponding connecting parts 12 on the two boards 10.

[0078] Specifically, the rotating member 31 may be provided with multiple gear sections 311, which are spaced apart along the length of the rotating member 31. Each gear section 311 can be connected to the rack section on two moving members 41 of a set of moving components 40. By providing multiple gear sections 311 on a single rotating member 31, the rotation of a single rotating member 31 can drive multiple sets of moving components 40 simultaneously, which improves operating efficiency.

[0079] like Figure 1In the illustrated embodiment, the two single boards 10 are a first single board 10a and a second single board 10b, which are spaced apart along the thickness direction of the single board 10. The connecting portions 12 on the first single board 10a and the second single board 10b can both be solder joints. Two contact connectors 21 are a first contact connector 21a and a second contact connector 21b, respectively. The first contact connector 21a is used to connect to the connecting portion 12 of the first single board 10a, and the second contact connector 21b is used to connect to the connecting portion 12 of the second single board 10b. The length of the cable 22 is greater than the gap width between the first single board 10a and the second single board 10b, which allows the cable 22 to not interfere with the movement of the first contact connector 21a and the second contact connector 21b. The two moving parts 41 are a first moving part 41a having a first rack portion and a first moving part 41b having a second rack portion. The end of the first moving part 41a near the first single plate 10a is fixedly connected to the first contact connector 21a, and the end of the first moving part 41b near the second single plate 10b is fixedly connected to the second contact connector 21b. Both the first rack portion and the second rack portion extend along the aforementioned thickness direction. One end of the rotating member 31 is provided with a gear part 311, and the other end of the rotating member 31 is provided with a handle 312. The handle 312 is located outside the gap between the first single plate 10a and the second single plate 10b, so as to facilitate the operator to manually rotate the rotating member 31. The two opposite ends of the gear part 311 are respectively engaged with the first rack part and the second rack part. When the rotating member 31 rotates, one end of the gear part 311 engages with the first rack part, which can drive the first moving member 41a to move in a direction close to or away from the first single plate 10a, thereby driving the first contact connector 21a to connect or separate from the connection part 12 of the first single plate 10a. The other end of the gear part 311 engages with the second rack part, which can drive the first moving member 41b to move in a direction close to or away from the second single plate 10b, thereby driving the second contact connector 21b to connect or separate from the connection part 12 of the second single plate 10b.

[0080] Please refer to Figure 2 In one embodiment, the rotating assembly 30 includes two rotating members 31, which are connected one-to-one with two moving members 41. When the rotating members 31 rotate, each rotating member 31 can drive the corresponding moving member 41 to move.

[0081] Thus, each rotating component 31 corresponds to one moving component 41, enabling independent control of the two moving components 41. This allows for individual adjustment of the moving distance, speed, and direction of each moving component 41 according to actual needs, facilitating the handling of more complex single-board 10 interconnection scenarios.

[0082] The cooperation between the rotating part 30 and the moving part 41 can be, but is not limited to, a gear and rack, a crank connecting rod and slider, or a lead screw and nut. For details, please refer to the above embodiments, which will not be repeated here.

[0083] Correspondingly, within the single-board assembly, the connecting portion 12 of the single-board 10 is disposed at the edge of the main body 11 and protrudes outward from the main body 11. In other words, the connecting portion 12 is arranged in the edge region of the main body 11 and protrudes outward from the surface of the main body 11, forming a physical extension structure. When the two rotating members 31 rotate, each moving member 41 drives the corresponding contact sensor to move in a direction closer to or away from the connecting portion 12.

[0084] Specifically, when the rotating member 31 rotates in the first rotation direction, the corresponding moving member 41 can move in the direction close to the corresponding connecting part 12. When the rotating member 31 rotates in the second rotation direction, the corresponding moving member 41 can move in the direction away from the corresponding connecting part 12.

[0085] In one embodiment, there are multiple moving components 40 and multiple connecting components 20. The two moving parts 41 of each moving component 40 are connected to the two contact connectors 21 of each connecting component 20 in a one-to-one correspondence. One of the two rotating parts 31 corresponds to and is connected to one moving part 41 of each group of moving components 40, and the other rotating part 31 corresponds to and is connected to the other moving part 41 of each group of moving components 40. When the rotating part 31 rotates, it drives the corresponding moving part 41 to move.

[0086] Each rotating member 31 may be provided with multiple gear portions 311, and each moving member 41 may be provided with a rack portion. Each gear portion 311 of the rotating member 31 meshes with the rack portion of the corresponding moving member 41.

[0087] Specifically, the rotating member 31 may also include a rod-shaped body 313, with a plurality of gear portions 311 sleeved on the body 313 and spaced apart along the length of the body 313. The body 313 and the plurality of gear portions 311 may be integrally formed, but are not limited thereto.

[0088] Correspondingly, within the single board assembly, each single board 10 includes multiple connecting parts 12. The multiple connecting parts 12 of one single board 10 correspond one-to-one with the multiple connecting parts 12 of the other single board 10. The connecting parts 12 of one single board 10 and the corresponding connecting parts 12 of the other single board 10 are connected by a connecting component 20.

[0089] This allows for the establishment of more precise interconnection channels between the two boards 10, which helps improve the connection efficiency between the two boards 10 and thus increase the signal transmission speed between the two boards 10.

[0090] Furthermore, the plurality of connecting portions 12 include at least a plurality of first connecting portions 121 and a plurality of second connecting portions 122, and the main body portion 11 includes a first side edge 111 and a second side edge 112; wherein, the plurality of first connecting portions 121 are located on the first side edge 111 and protrude from the first side edge 111, and the plurality of second connecting portions 122 are located on the second side edge 112 and protrude from the second side edge 112. The aforementioned first side edge 111 and second side edge 112 may be adjacent, spaced apart, or opposite to each other.

[0091] In this way, multiple interconnection channels between the two boards 10 can be distributed on different sides of the boards 10, effectively alleviating the interconnection pressure between one side of the boards 10 and improving the stability and reliability of the connection. Furthermore, with the connection parts 12 distributed on different sides of the boards 10, each port on a board 10 can select the interconnection channel closest to it to transmit signals to the other board 10, further improving the transmission efficiency between the two boards 10.

[0092] like Figure 2 In the illustrated embodiment, the main body 11 includes a first side edge 111, a second side edge 112, and a third side edge 113. The plurality of connecting parts 12 include a first connecting part 121, a second connecting part 122, and a third connecting part 123. The first connecting part 121 is disposed on the first side edge 111 and protrudes from the first side edge 111 in a second direction. The second connecting part 122 is disposed on the second side edge 112 and protrudes from the second side edge 112 in a third direction. The third connecting part 123 is disposed on the third side edge 113 and protrudes from the fourth side edge in a fourth direction.

[0093] The second side edge 112 connects the first side edge 111 and the second side edge 112. The first side edge 111 is parallel to the third side edge 113. The second side edge is perpendicular to both the first side edge 111 and the third side edge. The second direction is perpendicular to the third direction, and the direction of the second direction is opposite to the direction of the fourth direction.

[0094] In one embodiment, the movable component further includes an elastic element, which is fixedly connected to a corresponding contact connector 21.

[0095] Specifically, the movable component 41 has a first hook portion, and one end of the elastic component can be hooked onto the first hook portion for fixed connection with the movable component 41. The contact connector 21 may have a second hook portion, and the other end of the elastic component can be hooked onto the second hook portion, but it is not limited to this. For example, in other embodiments, one end of the elastic component can be pasted to the movable component 41, and the other end can also be pasted to the contact connector 21. Alternatively, the movable component 41 has a first snap-fit ​​groove, one end of the elastic component is snapped into the first snap-fit ​​groove, and the contact connector 21 has a second snap-fit ​​groove, the other end of the elastic component is snapped into the second snap-fit ​​groove. Of course, the elastic component can also be fixedly connected to the movable component 41 and the contact connector 21 respectively by other fixing methods, which will not be elaborated further.

[0096] The elastic element can absorb the mechanical stress generated by the moving part 41 during movement. When the rotating assembly 30 drives the moving part 41 to contact or separate the contact connector 21 from the connection part 12 of the single board 10, the elastic element buffers the impact through its own elastic deformation, avoiding damage to the connector or the connection part 12 of the single board 10 due to rigid collision.

[0097] The aforementioned elastic components can be springs, sheet metal, etc.

[0098] Furthermore, the contact connector includes a base and a contact portion for connecting the circuit board, the contact portion being designed to extend and retract relative to the base. This extension and retraction of the contact portion provides a buffering effect. At the moment of contact, the contact portion can first retract and then gradually extend to tightly fit the connection point of the circuit board, reducing the impact force during connection, protecting the contact portion and the connection point of the circuit board from damage, and extending their service life.

[0099] Specifically, the base may be provided with a sleeve for accommodating and fixing the contact part. One end of the contact part is fixed inside the sleeve of the base by an elastic part, and the other end is a free end, which is unrestrained and used to abut against the connecting part for connection.

[0100] When the contact portion comes into contact with the connecting portion 12 of the single plate 10, one end of the contact portion is fixed inside the sleeve of the base by an elastic part (such as a spring or spring sheet), while the other end is a free end. At the moment of contact, the single plate 10 exerts a force on the free end of the contact portion, causing the contact portion to be compressed and thus deforming the elastic part. Taking a spring as an example, a spring has the characteristic of elastic deformation. When compressed by an external force, it will undergo compression deformation. At this time, the contact portion will retract a certain distance into the sleeve, thereby absorbing part of the impact force and playing a buffering role. As the external force continues to act, after the spring is compressed to a certain extent, it will gradually generate a reverse elastic force. This elastic force will cause the contact portion to gradually extend. When the elastic force and the force exerted by the single plate 10 on the contact portion reach equilibrium, the contact portion will fit tightly with the connecting portion 12 of the single plate 10, completing the connection process.

[0101] In one embodiment, the contact connector 21 includes a magnetic part, which is used to magnetically connect with the corresponding board when the connection assembly 20 is in a first position.

[0102] Specifically, the single board 10 has a magnetic attraction part; when the connecting assembly 20 is in the first position, the magnetic attraction part and the magnetic attraction part are attracted and connected.

[0103] On the one hand, when the connecting assembly 20 switches from the second position to the first position, when the contact connector 21 approaches the board 10, the magnetic force between the magnetic attraction part and the magnetic mating part will generate a mutual attraction. This attraction can guide the contact connector 21 to automatically align with the connection part 12 on the board 10. On the other hand, when the connecting assembly 20 is in the first position, the continuous attraction between the magnetic attraction part and the magnetic mating part can provide stable contact pressure between the contact connector 21 and the connection part 12 of the board 10. This stable pressure helps to overcome the influence of external factors such as vibration and impact, ensures the stability of current or signal transmission, and reduces the failure rate caused by poor contact.

[0104] Furthermore, the contact connector 21 also includes a magnetic shield, a base, and a contact portion for connecting the connection portion 12. The contact portion, the magnetic shield, and the magnetic attraction portion are all mounted on the base, and the magnetic shield is located between the magnetic attraction portion and the contact portion, separating the magnetic attraction portion and the contact portion.

[0105] The magnetic shielding component prevents mutual interference between the two components, allowing the magnetic attraction part to focus on achieving the adsorption connection function with the magnetic mating part of the board 10, while the contact part can stably transmit current or signals. This separation of functions helps improve the overall reliability and stability of the contact connector 21, reduces the probability of failure caused by magnetic field interference, and ensures the normal operation of the entire board assembly.

[0106] The aforementioned magnetic shielding components may include ferromagnetic materials (such as pure iron and silicon steel) and metal oxides (such as ferrites), but are not limited to these.

[0107] In one embodiment, the interconnecting device further includes a limiting component that engages with the rotating component 30 when the connecting component 20 is in a first position.

[0108] Specifically, the limiting component includes limiting members, and the number of limiting members can be the same as the number of rotating members 31, with each limiting member corresponding to one rotating member 31.

[0109] The aforementioned limiting component may include a pin, and the rotating component 31 has a positioning hole. The pin can be inserted into or removed from the positioning hole manually or automatically. For example, when the connecting component 20 is in the first position, the user can manually insert the pin into the positioning hole of the rotating component 30 to restrict the rotational freedom of the rotating component 31. When it is necessary to rotate the rotating component 31, the pin can be removed. Alternatively, the aforementioned limiting component may include a buckle, and the rotating component 31 has a slot that matches the buckle. When the connecting component 20 is in the first position, the buckle engages with the slot to limit the rotation of the rotating component 31. When it is necessary to rotate the rotating component 31, a certain external force can be applied to deform the buckle and disengage it from the slot. Alternatively, the limiting component may be an electromagnetic lock, and the rotating component 31 has a locking part that cooperates with the electromagnetic lock. The electromagnetic lock consists of an electromagnet and a bolt, and the extension and retraction of the bolt are achieved by controlling the on and off of the electromagnet. When the connecting assembly 20 is in the first position, the electromagnetic lock is energized, the bolt extends and engages with the locking part of the rotating member 31, restricting the rotation of the rotating member 31. When it is necessary to rotate the rotating member 31, the power supply to the electromagnetic lock is disconnected, the bolt retracts, and the restriction is released.

[0110] With this configuration, when the connecting component 20 is in the first position, i.e., when the two boards 10 are connected through the connecting component 20, the rotating component 30 may rotate unexpectedly due to external vibrations, accidental touches, or other factors. The limiting component can effectively restrict the rotational freedom of the rotating component 30, ensuring that the connecting component 20 remains stably in the first position, thereby guaranteeing the stability of the connection between the two boards 10 and preventing the normal transmission of current or signals from being affected by a loose connection.

[0111] This application also provides a complete system, which may be, but is not limited to, a server system or a switch system.

[0112] The complete system includes a cabinet 50 and the single-board assembly described in any of the above embodiments or implementations. The cabinet 50 has installation space, within which the single-board assembly is installed.

[0113] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
