Abstract

This application discloses a connector plug, a server node, and a server, relating to the field of server technology. It includes a first fixing member, a first plug body, a connecting member, a fixing rod, and an elastic member. The first plug body is axially movable relative to the first fixing member. Simultaneously, through the cooperative structure of the fixing rod, connecting member, and elastic member, the first plug body can achieve axial adaptive floating adjustment when positional deviations occur during connector mating, utilizing the elastic force of the elastic member. This provides excellent assembly tolerance and deviation compensation capabilities, avoiding the shortcomings of traditional rigid connectors that lack adjustment margins and rely entirely on machining precision for alignment.

Description

Technical Field

[0001] This application relates to the field of server technology, and more particularly to a connector plug, a server node, and a server. Background Technology

[0002] With the rapid development of cloud computing, big data, and artificial intelligence technologies, the application scenarios of data center servers are becoming increasingly diversified, placing higher demands on the integration and connection reliability of internal server components. In server architecture design, the layout of network interface cards (NICs) and input / output ports is typically divided into two modes: front-out and rear-out, to adapt to the cabling specifications and heat dissipation requirements of different data centers. Currently, the industry commonly uses rigid, fixed connector structures to achieve electrical connections between server nodes and the chassis backplane or power module. This conventional technical solution usually involves directly locking the connector body to the server frame or beam with screws, relying on precision machining to ensure the alignment accuracy of the plug ends, and relying on manual or automated equipment to push the plug into the socket to complete the connection during assembly.

[0003] However, in existing server manufacturing and assembly processes, inherent dimensional tolerances in the processing of rack sheet metal parts, coupled with cumulative errors from multi-level assembly of the entire machine, often lead to significant positional deviations in high-density connectors during mating. This rigid connection method lacks necessary fault tolerance and adaptive adjustment capabilities, exposing the mating process to significant mechanical stress risks. A long-standing industry pain point is that when alignment deviations exceed allowable limits, forced insertion and removal can easily cause connector pin bending, contact hole collapse, or even interface breakage, leading to serious consequences such as unstable signal transmission or connection failure. This severely restricts the improvement of server product yield and operational efficiency, and also limits the flexible adaptability of a single model under different outgoing network modes. Summary of the Invention

[0004] This application provides a connector plug, server node, and server to at least solve the technical problems in related technologies, such as large alignment deviations, high insertion and extraction stress, easy bending of pins and collapse of holes, and poor contact caused by cabinet processing tolerances and cumulative assembly tolerances.

[0005] The first aspect of this application provides a connector plug, comprising: a first fixing member, a first plug body, a connecting member, a fixing rod, and an elastic member. The first fixing member has a first mounting opening, the first plug body is movably inserted into the first mounting opening, and one end of the first plug body forms a first insertion end and the other end forms a connection end. The connecting member is disposed on one side of the first fixing member and is fixedly connected to the connection end. The connecting member has a first mounting hole, the axis of which is parallel to the axis of the first mounting opening. The fixing rod movably passes through the first mounting hole and is connected to the first fixing member. The elastic member is connected between the fixing rod and the connecting member, and the elastic member is configured to provide an elastic force along the axial direction of the first mounting opening to the connecting member and the first plug body under the action of an external force, so as to drive the first plug body to float along the axial direction of the first mounting opening.

[0006] A second aspect of this application provides a server node, including a node frame and a first connector, the first connector being a connector plug as described above, one end of the node frame being provided with a support beam, and the connector plug being mounted to the support beam via a first fastener.

[0007] A third aspect of this application provides a server, including a housing and a server node as described above, the server node being detachably disposed inside the housing.

[0008] Through this application, since the first plug body can move axially relative to the first fixing member, and through the cooperative structure of the fixing rod, connecting member and elastic member, the first plug body can achieve axial adaptive floating adjustment by utilizing the elastic force of the elastic member when the connector docking produces positional deviation. It has good assembly fault tolerance and deviation compensation capabilities, avoiding the defects of traditional rigid connectors that have no adjustment margin and rely entirely on machining precision to ensure alignment. Therefore, it can solve the technical problems of existing server connectors, which have large docking alignment deviations due to sheet metal machining tolerances and multi-layer assembly cumulative errors, and the mechanical stress easily generated by forced insertion, causing damage to connector pins and interfaces and abnormal signal transmission. It effectively adapts to various application scenarios such as front-out and rear-out servers, and achieves the technical effects of significantly reducing the connector docking assembly failure rate, improving product assembly yield and connection reliability, while enhancing the flexibility of model and scenario adaptation and optimizing equipment operation and maintenance efficiency.

[0014] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1 to 4As shown, an embodiment of this application provides a connector plug, which includes a first fixing member 1, a first plug body 2, a connecting member 3, a fixing rod 4, and an elastic member 5. The first fixing member 1 has a first mounting opening, and the first plug body 2 is movably inserted into the first mounting opening. One end of the first plug body 2 forms a first insertion end 21, and the other end forms a connecting end. In this embodiment, the first fixing member 1 serves as the mounting base for the entire floating plug, used for fixed connection with external devices or panels. Its material can be a high-strength metal or a rigid engineering plastic to ensure connection stability. The first mounting opening penetrates the first fixing member 1, providing a guiding space for the axial movement of the first plug body 2. The first plug body 2, as the core component for realizing electrical connection, is slidably inserted into the first mounting opening, thus possessing the physical basis for free movement along the axial direction. One end of the first plug body 2 is designed as the first insertion end 21 for insertion into a suitable connector socket; the other end is the connecting end for fixed connection with the connecting member 3. It should be understood that the first plug body 2 and the first mounting port can be a clearance fit to reduce moving friction resistance, or a lubricating coating or self-lubricating material can be provided on the contact surface to further ensure the smoothness of floating.

[0016] The connector 3 is located on one side of the first fixing member 1 and is fixedly connected to the connecting end. The connector 3 has a first mounting hole 312, the axis of which is parallel to the axis of the first mounting opening. The connector 3 and the connecting end of the first plug body 2 can be fixed by means of threaded connection, interference fit, welding, or integral molding to ensure that the two remain synchronized during movement and do not undergo relative displacement. The first mounting hole 312 on the connector 3 provides a guide channel for the fixing rod 4. By configuring the axis of the first mounting hole 312 to be parallel to the axis of the first mounting opening, the direction of movement of the first plug body 2 is ensured to be consistent with the direction of action of the floating driving force, thereby avoiding jamming or accelerated wear caused by lateral force during movement.

[0017] The fixing rod 4 movably passes through the first mounting hole 312 and connects to the first fixing member 1. In this structure, the fixing rod 4 plays a dual role: on the one hand, it serves as a guide shaft for the movement of the connecting member 3 and the first plug body 2, restricting its rotational freedom and allowing it to only translate axially; on the other hand, it serves as a mounting base for the elastic member 5, with one end remaining relatively fixed to the first fixing member 1. The connection method between the fixing rod 4 and the first fixing member 1 can be threaded fastening, snap-fit ​​connection, or press-fit, etc., and the specific choice should be determined based on assembly convenience and strength requirements. The fixing rod 4 and the first mounting hole 312 also have a clearance fit to allow the connecting member 3 to slide axially along the fixing rod 4. In practical engineering applications, the surface finish of the fixing rod 4 has a significant impact on the floating performance; therefore, grinding is usually used to reduce the coefficient of friction.

[0018] The elastic element 5 connects the fixed rod 4 and the connector 3. The elastic element 5 is configured to provide an axial elastic force along the first mounting opening to the connector 3 and the first plug body 2 under external force, thereby causing the first plug body 2 to float axially along the first mounting opening. The elastic element 5 is the core component for achieving the floating function, and its typical implementation is a compression spring or a tension spring. When the first plug end 21 experiences external resistance from the adapter socket during insertion, this external force is transmitted to the connector 3 through the first plug body 2, thereby compressing or stretching the elastic element 5. By rationally designing the stiffness coefficient k, the elastic element 5 can provide sufficient and appropriate axial elastic force along the first mounting opening to the connector 3 and the first plug body 2 under external force. This elastic force drives the first plug body 2 to adaptively float axially, thereby automatically compensating for positional deviations caused by machining tolerances, accumulated assembly errors, etc., achieving flexible docking. It should be understood that the specific form of the elastic element 5 is not limited to a helical spring, but can also be other elements with elastic energy storage function such as rubber elastomers, bellows or disc springs, as long as they can provide the required axial elastic restoring force.

[0019] When the connector plug and adapter socket are inserted, if there is an axial positional deviation between them, the first insertion end 21 will first contact the socket and be subjected to an axial reaction force. This external force is transmitted to the connector 3 through the first plug body 2, causing the connector 3 to displace relative to the fixed rod 4, thereby compressing or stretching the elastic element 5 located between them. The elastic element 5 deforms and stores energy under the external force, simultaneously generating a reverse elastic restoring force. Under the action of the elastic restoring force, the connector 3 drives the first plug body 2 to make a slight floating movement along the axial direction of the first mounting port. This floating movement allows the first plug body 2 to automatically adjust its axial position until the first insertion end 21 is fully aligned with the socket and successfully inserted. When the external force is removed or the insertion is complete, the elastic element 5 releases the stored energy, driving the first plug body 2 to return to its initial equilibrium position.

[0020] The connector plug provided in this embodiment of the application has a first plug body 2 that can be movably inserted into the first mounting port and an elastic element 5 connecting the fixed rod 4 and the connector 3. When misalignment caused by tolerances occurs during the insertion process, the elastic element 5 can absorb axial errors through its own deformation and provide elastic restoring force, causing the first plug body 2 to adaptively float along the axial direction. Therefore, this structure effectively solves the problems of large misalignment and high insertion and extraction stress caused by machining tolerances and accumulated assembly tolerances in high-density connectors, avoids damage such as bent pins and collapsed holes caused by rigid mating, significantly reduces the risk of poor contact during insertion and extraction, and improves the connection reliability and service life of the connector.

[0021] like Figure 2and Figure 4 As shown, in some embodiments of this application, the first fixing member 1 includes two fixing blocks 11 spaced apart along a first direction. The first direction is perpendicular to the insertion direction. Taking the application of the connector plug on the server node as an example, the first direction is the width direction of the server node. The gap between the two fixing blocks 11 forms a first mounting opening. One end of the connector 3 is provided with a first sliding guide 311. The first fixing member 1 includes a second sliding guide 111. The first sliding guide 311 and the second sliding guide 111 slide in cooperation.

[0022] The two fixing blocks 11 can be fixed to the external equipment frame by fasteners 30. The material of the fixing blocks 11 can be high-strength aluminum alloy or stainless steel to ensure sufficient support rigidity. The specific shape of the fixing blocks 11 can be adapted to the needs of the installation space. For example, they can be rectangular blocks, stepped shapes, or structures with reinforcing ribs. This application embodiment does not make any special limitations in this regard.

[0023] Specifically, the first sliding guide 311 is disposed at one end of the connector 3 and moves synchronously with the connector 3 and the first plug body 2; the second sliding guide 111 is disposed on the first fixing member 1 and remains stationary. When the first plug body 2 is subjected to an external force and floats along the axis of the first mounting port, relative sliding occurs between the first sliding guide 311 and the second sliding guide 111. This sliding fit relationship constitutes a geometric constraint on the movement trajectory of the first plug body 2, making it only able to translate along a predetermined axis, and unable to rotate around the axis or wobble in a plane perpendicular to the axis.

[0024] In one optional embodiment, the first sliding guide portion 311 and the second sliding guide portion 111 can be configured as a slider and a groove. For example, the sidewall of the connector 3 can protrude to form a slider, serving as the first sliding guide portion 311, while corresponding grooves can be formed on the opposite inner surfaces of the fixing block 11, serving as the second sliding guide portion 111. The slider is embedded in the groove and can slide along the length of the groove. In another optional embodiment, a guide post and a guide sleeve can also be used, i.e., the first sliding guide portion 311 is a guide hole, and the second sliding guide portion 111 is a guide post, with the guide post inserted into the guide hole to form a clearance fit. Figure 3 and Figure 4As shown, the second sliding guide 111 is a guide post, and the first sliding guide 311 is a guide hole provided on the connector 3. The guide post is slidably inserted into the guide hole in a direction parallel to the axis of the first mounting port. Each fixing block 11 is provided with two guide posts, which respectively cooperate with the two guide holes on the connector 3, thus ensuring that the connector 3 and the fixing block 11 can only slide axially and cannot rotate. Regardless of the specific structural form adopted, the core is to restrict the freedom of the first plug body 2 to only axial movement through the contact cooperation of the first sliding guide 311 and the second sliding guide 111. This greatly improves the alignment accuracy and repeatability of the plug end while ensuring the floating function to absorb axial tolerances and vibrations.

[0025] Due to the sliding engagement design of the first sliding guide 311 and the second sliding guide 111, a stable sliding constraint pair is formed between the connector 3 and the first fixing member 1. This design effectively solves the problems of radial swaying, torsion, or skewness that are prone to occur during the elastic reset process of traditional floating plugs. When the first plug body 2 floats axially under the action of the elastic member 5, the first sliding guide 311 always slides along the path of the second sliding guide 111, forcing the first plug body 2 to maintain parallelism with the axis, ensuring that the first plug end 21 can be aligned when contacting the mating object, and avoiding pin bending, poor contact, or connector damage caused by posture deviation. This structure is particularly suitable for high-density connector mating scenarios, and can significantly absorb displacement errors caused by machining tolerances, assembly tolerances, and thermal expansion, while maintaining extremely high connection reliability. It has unique advantages such as compact structure, high guiding stiffness, and strong resistance to lateral disturbances.

[0026] Furthermore, in some embodiments of this application, the fixing block 11 further includes a third sliding guide portion 112. The third sliding guide portion 112 and the second sliding guide portion 111 are arranged sequentially along a direction parallel to the axis of the first mounting port, and the third sliding guide portion 112 is located on the side of the second sliding guide portion 111 away from the first sliding guide portion 311. The third sliding guide portion 112 serves as an axial extension or supplement to the second sliding guide portion 111. The two remain parallel along the axial direction of the first mounting port and are arranged sequentially. This arrangement significantly increases the coverage length of the guide structure in the axial direction. The third sliding guide portion 112 can be a groove, guide rail, or through hole formed on the surface of the fixing block 11. Its specific shape can be designed according to the actual required guiding accuracy and load-bearing capacity. For example, it can be a dovetail groove, T-groove, or rectangular groove, or it can be a continuous guide surface with the same or different cross-sectional shape as the second sliding guide portion 111. By setting guide portions at different axial positions, it is possible to effectively avoid cantilever or guide failure at the end of the floating stroke of the connector 3, thereby improving the motion stability of the entire floating plug within a large displacement range.

[0027] For example, such as Figure 3 and Figure 4 As shown, the connector 3 includes two connecting blocks 31 and two connecting plates 32. The two connecting blocks 31 are spaced apart along a first direction on both sides of the connecting end of the first plug body 2, and the two connecting blocks 31 are corresponding one-to-one with the two fixing blocks 11. The two connecting plates 32 are spaced apart along a second direction, which is perpendicular to both the insertion direction and the first direction. Taking the connector plug as an example in a server node, the second direction is the height direction of the server node. The two connecting plates 32 are connected to the upper and lower ends of the connecting blocks 31, respectively. Specifically, they can be fixed by screws, welding, or bonding. The purpose is to achieve relative fixation between the connecting plates 32 and the connecting blocks 31 so that they can move synchronously. The connecting plates 32 are provided with insertion holes, and the upper and lower sides of the first plug body 2 are provided with protrusions for insertion into the insertion holes, thereby achieving relative fixation between the connecting plates 32 and the first plug body 2 so that they can move synchronously.

[0028] The first sliding guide part 311 is a guide hole provided on the connecting block 31, the second sliding guide part 111 is a guide post provided on the fixed block 11, the front end of the connecting plate 32 protrudes from the end face of the connecting block 31 along the insertion direction to form the fourth sliding guide part, the fixed block 11 is rectangular in shape, and the upper and lower surfaces of the fixed block 11 respectively form the third sliding guide part 112, which slides in cooperation with the fourth sliding guide part.

[0029] The connector 3 has a first mounting channel 313 at one end away from the first sliding guide 311. The first mounting channel 313 is coaxially connected to the first mounting hole 312. The diameter of the first mounting channel 313 is larger than the diameter of the first mounting hole 312, so as to form a first connecting part around the first mounting hole 312. The fixed rod 4 has a second connecting part 42 that protrudes radially at one end away from the fixed member. An elastic ring is sleeved on the fixed rod 4, and the two ends of the elastic member 5 are respectively connected to the first connecting part and the second connecting part 42.

[0030] The first mounting channel 313 and the first mounting hole 312 together form a stepped hole structure on the connector 3. This structure utilizes the annular end face formed by the change in hole diameter as the first connecting part. The hole diameter of the first mounting channel 313 can be adaptively designed according to the outer diameter of the elastic element 5, as long as the hole diameter of the first mounting channel 313 is larger than the hole diameter of the first mounting hole 312, thus leaving sufficient annular contact surface. For example, when the first mounting hole 312 is used to guide and fix the rod 4, the hole diameter of the first mounting channel 313 can be 2mm to 10mm larger than the hole diameter of the first mounting hole 312. This application embodiment does not impose any special limitation on this.

[0031] The fixing rod 4 includes a rod body 41, with a second connecting portion 42 formed radially protruding from the end of the rod body 41 away from the fixing member. The second connecting portion 42 is used to cooperate with the elastic member 5 to form an axial limit on one end of the elastic member 5. In this application, the second connecting portion 42 can be integrally formed with the rod body 41. For example, a radial boss can be directly formed at the end of the rod body 41 by cold heading, or the rod body 41 can be designed as a bolt structure, using the bolt head as the second connecting portion 42. This integrated structural design avoids the failure risk caused by welding deformation or thread loosening, ensuring the reliability of the connection between the second connecting portion 42 and the rod body 41 under high-frequency floating conditions.

[0032] The elastic element 5 is typically in the form of a compression spring, sleeved on the outside of the rod body 41. The rod body 41 serves as a guide shaft to prevent buckling of the elastic element 5 during compression. One end of the elastic element 5 abuts against the end face of the first connecting portion, and the other end abuts against the end face of the second connecting portion 42. This application constructs a closed elastic force loading chamber through the coordinated cooperation of the first connecting portion and the second connecting portion 42. When the connector plug is subjected to external force, the first plug body 2 drives the connecting member 3 to move relative to the rod body 41, forcing the elastic element 5 to undergo compression or elongation deformation between the first connecting portion and the second connecting portion 42, thereby outputting an elastic restoring force.

[0033] Specifically, the installation structure of the elastic element 5 utilizes the annular end face of the stepped hole as the first connecting part, which, together with the second connecting part 42 at the end of the rod body 41, achieves axial pre-tightening and positioning of the elastic element 5. During assembly, simply insert the elastic element 5 into the rod body 41, then pass the rod body 41 through the first mounting hole 312 of the connector 3, positioning the second connecting part 42 within the first mounting channel 313, thus completing the installation of the elastic element 5. This blind-installation design significantly reduces assembly difficulty and improves production efficiency. Simultaneously, since the first connecting part and the second connecting part 42 are located on the connector 3 and the rod body 41 respectively, they maintain a clamping state on the elastic element 5 during relative movement, effectively preventing the elastic element 5 from falling off or losing pre-tightening force due to axial movement during long-term reciprocating motion.

[0034] The fixing block 11 is provided with a threaded hole, and the rod body 41 is provided with a threaded section. The threaded section is screwed into the threaded hole to fix the fixing rod 4 to the fixing block 11.

[0035] As a component of the first fixing element 1, the threaded hole on the fixing block 11 provides a connection base. This threaded hole can be a through hole or a blind hole, and can be designed according to the thickness and structural strength requirements of the fixing block 11. The threaded section on the rod body 41 refers to the area on the surface of the rod body 41 with a threaded structure, which matches the internal thread of the threaded hole. By rotating the rod body 41, the threaded section is screwed into the threaded hole, and the self-locking characteristic of the threaded pair achieves a tight connection between the fixing rod 4 and the fixing block 11. This threaded connection method is simple in structure, easy to assemble and disassemble, and allows for precise adjustment of the relative position of the fixing rod 4 in the axial direction by rotating it. This facilitates the adjustment of the pre-compression of the elastic element 5 sleeved on the fixing rod 4 to adapt to different tolerance requirements in docking conditions, while ensuring the reliability of the connection under vibration and preventing loosening. The specific tooth profile, nominal diameter, and pitch of the threaded hole and threaded section can be selected according to the actual load and space constraints; this embodiment does not impose any special limitations on these parameters.

[0036] Furthermore, the connector plug in this embodiment of the application also includes a guide pin 6. The guide pin 6 is arranged in a direction parallel to the axis of the first mounting port, and one end of the guide pin 6 is fixedly connected to the connector 3, while the other end movably passes through the first fixing member 1 and protrudes from the first plug end 21.

[0037] In practice, the guide pin 6 is typically made of a rigid material, such as metal or high-strength engineering plastic, to ensure that it is not easily bent or deformed under lateral forces. One end of the guide pin 6 is fixedly connected to the connector 3 by means of integral molding, threaded connection, welding, or interference fit, ensuring that the guide pin 6 can move synchronously with the connector 3. The other end of the guide pin 6 protrudes beyond the first plug end 21, that is, the free end of the guide pin 6 extends axially beyond the plug end face of the first plug body 2, so that it contacts the guide structure on the adapter socket before the first plug body 2 in the initial stage of plugging.

[0038] During connector mating, the guide pin 6 acts as a primary guide component, pre-intervening and correcting positional deviations between the first plug body 2 and the adapter socket in the direction perpendicular to the mating axis. When the guide pin 6 is inserted into the guide mating hole 6011 corresponding to the adapter socket, if there is a center alignment deviation, the side wall of the guide mating hole 6011 will press against the side of the guide pin 6. This lateral pressing force will drive the connector 3 to automatically slide the first plug body 2 towards the center position, achieving automatic correction. This coarse positioning mechanism can effectively eliminate deviations caused by machining tolerances, assembly errors, or vibration accumulation, preventing the guide pin 6 of the first plug body 2 from directly colliding with the adapter socket, thereby protecting the precision connector contacts from damage and significantly reducing the difficulty of blind mating, improving the success rate and reliability of mating.

[0039] Furthermore, the end of the guide pin 6 away from the connector 3 is provided with a guide bevel.

[0040] A guide bevel is disposed at the end of the guide pin 6 to provide guidance when the guide pin 6 is inserted into the corresponding guide mating hole 6011. This guide bevel can be an inclined surface formed at the end of the guide pin 6 by cutting, chamfering, or molding. When there is a slight center deviation between the guide pin 6 and the guide mating hole 6011, the guide bevel can reduce the contact area between the guide pin 6 and the edge of the mating hole during the initial insertion stage, converting part of the axial insertion resistance into a radial force. This radial force automatically corrects the positional deviation of the guide pin 6, thereby guiding the guide pin 6 smoothly into the guide mating hole 6011. In practical applications, the shape of the guide bevel can be set according to the actual working conditions. For example, it can be a conical surface, a pyramidal surface, or a rounded curved surface, as long as it can reduce the insertion resistance and guide the guide pin 6 smoothly into the guide mating hole 6011. This application embodiment does not impose any special limitations on this. By setting a guiding bevel at the end of the guide pin 6, the bending or jamming of the guide pin 6 caused by hard collision can be effectively avoided during the coarse positioning stage of connector mating. This improves the adaptive mating capability of the floating plug in the presence of alignment deviation, thereby improving the mating smoothness, reducing the insertion and extraction stress, and protecting the integrity of the guide pin 6 structure.

[0041] like Figure 5 As shown, this application embodiment also provides a server node, which includes a node frame 40 and a first connector 10. The first connector 10 adopts a connector plug as described in the above embodiment. One end of the node frame 40 is provided with a support beam 20, and the connector plug is installed on the support beam 20 through a first fixing member 1.

[0042] The node frame 40 serves as the main load-bearing structure of the server node, housing core components such as the motherboard, power supply, and cooling system, and providing a mounting base for external interface modules. The node frame 40 is typically made of metal (such as aluminum alloy or galvanized steel sheet), offering good structural strength and electromagnetic shielding performance. The support beam 20 extends horizontally, and its surface is machined with mounting holes or threaded interfaces for securing connectors, ensuring that connector plugs can be securely mounted on the node frame 40.

[0043] like Figures 6 to 9 As shown, the first connector 10 serves as an interface unit for data exchange between the server node and an external network or storage device, and adopts the connector plug structure described in the aforementioned embodiments. This connector plug is mounted on the support beam 20 of the node frame 40 via its first fixing member 1. Specifically, the first fixing member 1 and the support beam 20 can be detachably connected via fasteners 30 (such as screws or bolts), or can be installed using quick-release structures such as clips or slide rails.

[0044] In some embodiments of this application, the first fixing member 1 and the supporting beam 20 are radially floatingly engaged along the first mounting opening via a floating mechanism.

[0045] The floating mechanism is used to achieve relative displacement of the first fixing member 1 relative to the support beam 20 in a direction perpendicular to the axis of the first mounting opening, i.e., radial floating. Exemplarily, this radial floating direction may include a first direction and a second direction. This radial floating fit is typically achieved by reserving a radial clearance at the connection interface between the first fixing member 1 and the support beam 20, or by employing a specific elastic connection structure. For example, the first fixing member 1 and the support beam 20 can be connected by a hole-shaft fit with radial clearance, or by setting an elastic buffer element, so that when the first fixing member 1 is subjected to radial external force, it can generate a slight translation relative to the support beam 20, and maintain this position or reset after the external force is removed, thereby absorbing radial dimensional deviations caused by factors such as machining tolerances, assembly errors, or thermal deformation.

[0046] This design enables the connector plug to float not only along the axial direction of the first mounting port, but also in the first and second radial directions, thus creating a three-axis fully floating docking structure. During the mating process at the server node, when there is a radial center deviation between the first insertion end 21 of the first plug body 2 and the adapter socket, the floating mechanism allows the first fixing member 1 to automatically offset the entire floating plug radially to conform to the position of the socket. This avoids lateral forces caused by rigid mating, effectively solving the technical problems of high-density connectors being difficult to align under tolerance accumulation, which can easily lead to pin bending or poor contact. This significantly improves the reliability, fault tolerance, and service life of the connector mating.

[0047] In a specific implementation, the support beam 20 is provided with a second mounting port 201, and the first plug-in end 21 can movably pass through the first mounting port and the second mounting port 201; the floating mechanism includes a fastener 30 and a second mounting hole 202 provided on the support beam 20. The fastener 30 passes through the second mounting hole 202 and is fixedly connected to the first fixing member 1. There is a gap between the outer wall of the fastener 30 and the inner wall of the second mounting hole 202, so that the fastener 30 floats radially in the second mounting hole 202.

[0048] The second mounting opening 201 on the support beam 20 is mainly used to provide clearance space for the first plug end 21 of the first plug body 2 on the server node frame 40, ensuring that the first plug end 21 can pass smoothly through the support beam 20 and be plugged into the external docking component. The geometry and size of the second mounting opening 201 are adaptively designed according to the outline of the first plug end 21. For example, it can be set as a rectangular hole, a circular hole, or an oblong hole. Its core is to allow the first plug end 21 to pass through unobstructed while retaining sufficient room for movement to accommodate subsequent floating adjustments.

[0049] The floating mechanism mainly consists of a fastener 30 and a second mounting hole 202 formed on the supporting beam 20. The fastener 30 passes through the second mounting hole 202 and is fixedly connected to the first fixing member 1, thereby suspending the connector plug entirely on the supporting beam 20. In this embodiment, the fastener 30 can be a stepped screw, bolt, or other fastening element with a shank and a head, its end being screwed into a threaded hole on the first fixing member 1. The diameter of the second mounting hole 202 is typically larger than the diameter of the shank of the fastener 30; this dimensional difference provides the necessary physical space for the radial movement of the fastener 30 within the hole.

[0050] Based on the above structure, the gap formed between the outer wall of the fastener 30 and the inner wall of the second mounting hole 202 releases the radial rigid constraint between them, allowing the fastener 30 to float radially within the second mounting hole 202. When the first plug end 21 is subjected to lateral force during insertion, or when there is a deviation in the mating position due to the tolerance of the cabinet sheet metal processing or the cumulative tolerance of the whole machine assembly, the fastener 30 can undergo a slight radial displacement within this gap range, thereby causing the first fixing member 1 and the first plug body 2 mounted thereon to adaptively float relative to the support beam 20. This radial floating mechanism can automatically correct the alignment deviation and effectively avoid connector damage or poor contact caused by hard mating. The specific value of the gap can be set according to the tolerance estimate and the required floating amount in the actual application scenario, for example, set between 0.5mm and 2.0mm, which is not strictly limited in this application.

[0051] Furthermore, such as Figure 9 As shown, the fastener 30 includes a connecting rod 301 and a stop portion 302. The connecting rod 301 passes through the second mounting hole 202, and the diameter of the connecting rod 301 is smaller than the diameter of the second mounting hole 202. One end of the connecting rod 301 is fixedly connected to the first fixing member 1, and the other end is provided with a radially protruding stop portion 302, which is located on the side of the second mounting hole 202 away from the first fixing member 1.

[0052] The connecting rod 301 can be made of high-strength metal, such as carbon steel, stainless steel, or aluminum alloy, to ensure its structural strength. The connection between the connecting rod 301 and the first fixing member 1 can be achieved through threaded connection, welding, riveting, or integral molding, etc., and this embodiment does not impose any special limitations on this. Since the diameter of the connecting rod 301 is smaller than the diameter of the second mounting hole 202, a radial gap exists between the outer wall of the connecting rod 301 and the inner wall of the second mounting hole 202. The size of this radial gap can be set according to the actual radial float required by the server node, for example, it can be from 0.5mm to 2.0mm, thereby allowing the first fixing member 1 to undergo slight radial displacement relative to the supporting beam 20 to accommodate assembly tolerances and thermal expansion and contraction.

[0053] A stop portion 302 is located at the end of the connecting rod 301 away from the first fixing member 1 and protrudes radially along the connecting rod 301. The stop portion 302 is used to restrict the axial freedom of movement of the connecting rod 301 and prevent the connecting rod 301 from disengaging from the second mounting hole 202. The shape of the stop portion 302 can be disc-shaped, flange-shaped, or polygonal boss-shaped, as long as its radial dimension is larger than the diameter of the second mounting hole 202. The stop portion 302 and the connecting rod 301 can be an integrally formed structure or a separate connection structure, for example, fixed to the end of the connecting rod 30128 by means of thread fastening, snap connection, or welding. The stop portion 302 is located on the side of the second mounting hole 202 away from the first fixing member 1, that is, the stop portion 302 forms a limiting block on the second mounting hole 202 in the axial direction. When the first fixing member 1 is subjected to a tensile force along the axial direction away from the support beam 20, the stop part 302 will contact the surface of the support beam 20, thereby preventing the connecting rod 301 from being pulled out of the second mounting hole 202, ensuring the reliability of the connection between the connector plug and the support beam 20, and avoiding accidental detachment during maintenance or transportation.

[0054] like Figure 10 As shown, this application also provides a server, which includes a chassis (not shown in the figure) and a server node 100 as described in the above embodiments. The server node 100 is detachably disposed inside the chassis. The chassis serves as the external encapsulation structure of the server, providing physical support, electromagnetic shielding, and a heat dissipation environment, and its interior forms an installation space to accommodate the server node 100.

[0055] The server also includes a second connector 60. The second connector 60 is fixed inside the enclosure, and when the server node 100 is installed inside the enclosure, the first connector 10 and the second connector 60 are plugged into each other.

[0056] The second connector 60, as an interface component fixedly installed inside the enclosure, is used to form a mating connection with the first connector 10 installed on the server node 100. The specific type of the second connector 60 can be selected according to the signal transmission requirements of the actual application scenario; for example, it can be a high-speed signal connector, a power connector, or a composite connector, etc., and this embodiment does not impose any special limitations on this. The second connector 60 is typically fixedly installed at a specific location within the enclosure, such as on the back panel, crossbeam, or a specially designed bracket to ensure its positional stability. During the process of pushing the server node 100 into the enclosure, the first connector 10 and the second connector 60 automatically align and plug into each other through a guide structure, thereby establishing an electrical and mechanical connection between the server node and the enclosure. This plug-in method replaces traditional cable connections, achieving plug-and-play functionality between the server node and the enclosure, effectively improving assembly efficiency and connection reliability.

[0057] Through the above technical solution, this application achieves rapid interconnection between the server node 100 and the interior of the enclosure. By setting a fixed second connector 60 inside the enclosure, it automatically mates with the first connector 10 on the server node 100 during node installation, eliminating the need for manual cable plugging and unplugging or complex fixing operations. This significantly simplifies the server assembly and maintenance process and improves operational efficiency. Simultaneously, because the first connector 10 adopts a floating connection structure, combined with the fixed setting of the second connector 60, the two can automatically adapt to processing tolerances and assembly errors during the docking process, avoiding connector damage or poor contact caused by hard docking, and ensuring the long-term stability and signal transmission quality of the server.

[0058] Among them, such as Figure 13 As shown, the second connector 60 includes a second fixing member 601 and a second plug body 602. The second fixing member 601 is configured to fix the second plug body 602 to the housing. The second fixing member 601 is provided with a guide mating hole 6011, which is configured to engage with the guide pin 6 on the first connector 10. One end of the guide mating hole 6011 is set to be tapered along the insertion direction.

[0059] The second fastener 601 is used to securely install the second plug body 602 inside the server chassis. Its specific structure can be adapted to the spatial layout inside the chassis. The second plug body 602, as the core component that mates with the first connector 10, has terminals inside for transmitting signals or current. In the above structure, one end of the guide hole 6011 is designed as a tapered shape along the insertion direction. This tapered structure is typically designed as a tapered hole or a flared shape, with its diameter gradually decreasing along the insertion direction. When the first connector 10 approaches the second connector 60, the guide pin 6 first contacts the tapered, larger diameter end of the guide hole 6011. Guided by the tapered hole wall, the guide pin 6 is automatically corrected to a position coaxial with the guide hole. As the insertion depth increases, the guide pin 6 smoothly slides into the smaller diameter straight hole section, achieving precise alignment.

[0060] Through the above technical solution, this application achieves adaptive guiding docking between the second connector 60 and the first connector 10. Since one end of the guide hole 6011 is set to a tapered shape along the insertion direction, this tapered hole and the guiding slope of the guide pin 6 work together to form a self-aligning guiding mechanism. In the initial stage of insertion, even if there is a certain horizontal or vertical deviation between the first connector 10 and the second connector 60, the tapered guide hole 6011 can use its geometry to force the insertion path to converge, smoothly guiding the guide pin 6 to the correct position. This design significantly improves the success rate and smoothness of blind mating, effectively avoiding bending, scratching, or hole wall damage to the guide pin 6 due to misalignment, protecting the precision connector components, and extending their service life.

[0061] The server includes a chassis and a power supply 200 housed within the chassis. The power supply 200 is fixedly located on the side of the second connector 60 furthest from the server node 100 and is electrically connected to the second connector 60. The power supply 200 provides power to the entire server system, ensuring the stable operation of the server node. The power supply 200 has a first network interface card (NIC) port 50 exposed on the side wall of the chassis, and / or, the server node 100 has a second NIC port 70 exposed on the side wall of the chassis at the end furthest from the power supply.

[0062] The first network interface card (NIC) port 50 and the second NIC port 70 are located on different side walls of the enclosure, such as the rear window side wall and the front window side wall, respectively, for network signal input and output. This layout design allows the server to support both front-out mode (network connection via the second NIC port 70 on the server node) and rear-out mode (network connection via the first NIC port 50 on the power supply). Users can flexibly choose to connect the OCP (Open Compute Project) NIC 80 to either the first NIC port 50 on the front window or the second NIC port 70 on the rear window, depending on the cabling requirements of the actual data center environment. This achieves server compatibility for both front and rear outgoing cabling scenarios, greatly improving the server's versatility and market adaptability, and avoiding the increased costs and extended delivery cycles caused by redesigning the server structure for different outgoing cabling requirements.

[0063] In practice, the node frame 40 contains electrical components such as memory and motherboard. The first network card port 50 and the first connector 10 are located at both ends of the node frame 40 and are electrically connected to the electrical components inside the node frame 40 to achieve signal transmission. The power supply fixed in the enclosure has a second network card port 70, which is electrically connected to the second connector 60. When the server node is installed in the enclosure, the first connector 10 and the second connector 60 are plugged in accordingly. Thus, the second network card port 70 is electrically connected to the electrical components inside the node frame 40 through the second connector 60 and the first connector 10, thereby achieving signal transmission.

[0064] For example, an embodiment of this application provides a server node applied to a 2U high-density server chassis, such as... Figure 11 As shown, the server node mainly includes a node frame 40, a slide rail 402, a first connector 10, a support beam 20, a handle assembly 90, an elastic latch 403, a base 300, rivets, rollers, brackets, locking components, and bosses.

[0065] The handle assembly 90 consists of a handle rivet, a pin, a torsion spring 903, a handle 901, a handle screw, and a hand screw 902. The handle rivet and the pin are riveted to the node frame 40. The torsion spring 903 is assembled between the handle 901 and the node frame 40. The handle 901 rotates around the handle screw. When the hand screw 902 is tightened, the handle 901 remains locked. When the hand screw 902 is loosened, the torsion spring 903 releases its elastic force to drive the handle 901 to automatically spring open.

[0066] The elastic buckle 403 is riveted and fixedly installed on the node frame 40; the elastic buckle 403 has a slanted boss 405 and an unlocking pressing position 404; the outer diameter of the head of the I-beam 407 is larger than the corresponding limiting hole diameter of the elastic buckle 403, which limits the pressing stroke of the unlocking pressing position 404 and prevents overpressure damage to the structural components; the slanted boss 405 has a slanted surface on the outside. When the server node 100 is pulled out and pushed into the base 300, the slanted surface can automatically retract inward due to the pressure, without the need for manual unlocking.

[0067] The connector plug is assembled onto the support beam 20 by four fasteners 30. The diameter of the second mounting hole 202 on the support beam 20 for the fasteners 30 is larger than the outer diameter of the connecting rod 301 of the fastener 30, and the outer diameter of the step of the unthreaded section of the fastener 30 is larger than the thickness of the plate of the support beam 20. This structure allows the first plug body to have radial floating margin on the support beam 20. The connector plug has a built-in elastic element 5, and the elastic element 5 is given a preset compression amount according to the estimated tolerance of the housing during assembly. The elastic force of the elastic element 5 is set to be greater than the insertion and extraction force of the first plug 10 and the second plug 60 separating from each other.

[0068] Rivets and rollers are riveted to the base 300; the side brackets and locking fasteners are fixed to the base 300 with rivets; the locking fasteners have bosses; the handle 901 has a V-shaped groove; after the node frame 40 is fully pushed into place, rotate the handle 901, the V-shaped groove engages with the boss, and tighten the hand screw 902 to complete the mechanical locking of the node frame 40. The bracket has bracket holes; during the outward pulling of the node frame 40, the inclined boss 405 of the elastic buckle 403 slides into the bracket hole, and the inclined boss 405 bears the load and supports the entire server node 100; the operator manually presses the unlocking press position 404, the inclined boss 405 retracts inward and disengages from the bracket hole, and the node frame 40 can be completely removed, achieving anti-fall protection.

[0069] Assembly process: Assembling the server node: First, install and fix the slide rail 402 to the node frame 40; install the connector plug on the support beam 20 and lock it using four fasteners 30; radial floating is achieved by utilizing the difference in diameter between the fasteners 30 and the second mounting hole 202 on the support beam 20; the connector plug has a built-in elastic element 5 that allows for axial floating. Then, rivet the handle and I-beam to the node frame 40; install the torsion spring and handle in sequence, and complete the hinge with the handle screw; rivet the elastic lock to the node frame 40, and the I-beam provides overpressure limiting protection for the elastic lock.

[0070] Assemble the base: Rivet the rivets and rollers to the base 300; fix the bracket and fastener to the base 300 with rivets; align the mounting holes on the second fastener 601 with the cylindrical positioning on the base 300 and lower it, then tighten the hand-turned screws.

[0071] The insertion process is as follows: Loosen the hand screw, and the handle will spring open under the action of the torsion spring; the slide of the node frame 40 is aligned with the gap between the roller and the rivet and pushed in; the inclined surface of the inclined boss 405 on the elastic lock 403 is automatically pushed back under pressure, and it can be installed without unlocking; when pushed in, the side wall of the guide mating hole 6011 on the second fixing part 601 presses the guide pin 6, which drives the entire connector plug to make radial adaptive floating, eliminate the housing machining tolerance, and complete the coarse positioning of the connector plug; push in further, and rely on the radial floating mechanism to achieve fine positioning; after it is in place, rotate the handle, and the handle's figure-eight groove engages with the locking buckle boss, tighten the hand screw to lock the pull-out node; complete the motherboard cable wiring; the OCP network card 80 can be plugged into the first network card port 50 of the front window or the second network card port 70 of the rear window according to the project requirements.

[0072] Disassembly procedure: Loosen the hand screw 902, and the torsion spring 903 will drive the handle 901 to spring open; hold the handle 901 and pull the server node 100 outward; as the server node 100 moves outward, the inclined protrusion 405 of the elastic lock 403 falls into the bracket hole, supporting the server node 100 and preventing it from falling; while the operator is holding the server node, press the unlocking button 404, and the inclined protrusion 405 will retract inward and disengage from the bracket hole, allowing the server node 100 to be completely pulled out of the enclosure.
