Technical Field

[0001] This invention relates to the field of semiconductor testing technology, and in particular to a power supply device and chassis. Background Technology

[0002] In semiconductor automated testing equipment, the test head chassis is a core component, containing a circuit board rack for mounting power supply boards, signal boards, etc.

[0003] In existing technical solutions, a distributed power supply design is typically adopted, where each functional board is equipped with an independent power supply device. However, as the complexity of the test system increases and the number of test channels grows, the above design leads to a linear increase in the number of power supply devices within the chassis. Each power supply device not only requires a certain amount of installation space but also generates corresponding wiring space requirements, which significantly increases the size of the test head chassis, posing a challenge to the miniaturization and high-density integration of the equipment.

[0011] In an optional embodiment, the first conductive female connector further includes a first plug-in portion connected to the first connecting portion. The first plug-in portion has a first plug-in hole, and the outer surface of the first plug-in portion is provided with a first limiting groove.

Detailed Implementation

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] A first aspect of the present invention provides a power supply device, such as... Figures 1 to 5 As shown, it includes a first copper strip 1, a second copper strip 2, an insulating shell 3, an insulating base 4, and at least one conductive component 5; The first copper strip 1 and the second copper strip 2 are arranged parallel to each other and spaced apart inside the insulating shell 3. The first copper strip 1 has a first insert finger 11 protruding towards the second copper strip 2, and the second copper strip 2 has a second insert finger 21 protruding towards the first copper strip 1. The first insert finger 11 and the second insert finger 21 are arranged alternately, and the arrangement direction is parallel to the length direction of the first copper strip 1 and the second copper strip 2. The bottom end of the insulating base 4 is connected to the insulating shell 3. The conductive components 5 are all installed in the insulating base 4 and each has a first insertion hole 5121 and a second insertion hole 5221 for inserting the corresponding board 6. The first insertion finger 11 and the second insertion finger 21 are electrically connected to the conductive components 5 to supply power to the corresponding board 6.

[0026] The aforementioned power supply device can be configured with a corresponding number of conductive components 5 according to the number of boards 6, enabling a single power supply device to simultaneously provide power to one or more boards 6. This power supply device achieves centralized management of power resources, solving the space occupation and wiring redundancy problems caused by multiple independent power supply devices in traditional distributed power supply designs. It significantly reduces the overall size and wiring complexity of the power supply device and improves the space utilization rate within the test head chassis.

[0027] In addition, such as Figure 5 As shown, the first insert portion 11 and the second insert portion 21 form a conductive structure with an insert-like distribution. Since the arrangement direction of the first insert portion 11 and the second insert portion 21 is parallel to the length direction of the first copper strip 1 and the second copper strip 2, and the conductive component 5 is connected to the first insert portion 11 and the second insert portion 21, as... Figure 6 and Figure 7As shown, the first insertion hole 5121 and the second insertion hole 5221 occupy a smaller dimension d1 in the width direction of the two copper strips than the dimension d2 occupied when the two copper strips are designed with equal width everywhere. This effectively shortens the space occupied by the conductive component 5 in the width direction when connecting the first copper strip 1 and the second copper strip 2. Since the conductive component 5 is disposed in the insulating base 4, the dimension occupied by the insulating base 4 in the above-mentioned direction can be reduced at the same time, further reducing the space occupied by the power supply device itself.

[0028] It should be noted that the first copper bar 1 and the second copper bar 2 are connected to an external power source, forming a P-pole copper bar and a N-pole copper bar. Specifically, the first copper bar 1 and the second copper bar 2 have independent power supply control, which can improve system safety and flexibility and solve the problem that a single point of failure may cause the entire system to lose power in the prior art.

[0029] In alternative implementations, such as Figure 4 As shown, the insulating shell 3 adopts a split structure design, including a base 31 and a cover 32. The cover 32 is detachably connected to the base 31, and the two are connected by means of snap-fit, screw fastening, etc., forming a receiving cavity inside. The first copper strip 1 and the second copper strip 2 are both set in the above-mentioned receiving cavity to achieve physical isolation of the power transmission path and electrical safety protection.

[0030] Among them, such as Figure 8 and Figure 9 As shown, at least one of the base 31 and the cover 32 is provided with a partition assembly 33, which is located in the gap area between the first copper strip 1 and the second copper strip 2, thereby further isolating the two conductive copper strips in space and improving the insulation reliability and electromagnetic compatibility of the product.

[0031] by Figure 9 For example, the cover 32 is provided with a partition assembly 33. The partition assembly 33 can be made of insulating material, such as flame-retardant engineering plastic, which has good dielectric strength and heat resistance, and can effectively prevent arc discharge or creepage between the first copper bar 1 and the second copper bar 2 due to excessive voltage difference, thus significantly improving the electrical safety of the power supply device.

[0032] In alternative implementations, such as Figure 9 As shown, the partition assembly 33 includes a first partition 331 and a second partition 332. The first partition 331 is disposed between the first insertion finger 11 of the first copper strip 1 and the main body of the second copper strip 2 to completely isolate the first insertion finger 11 from the adjacent second copper strip 2 in space. Correspondingly, the second partition 332 is disposed between the second insertion finger 21 of the second copper strip 2 and the main body of the first copper strip 1 to achieve symmetrical insulation protection.

[0033] With the above arrangement, the first partition 331 and the second partition 332 are respectively located in the gap between the intersecting areas of the two copper strips. Without interfering with the alternating arrangement of the first insertion part 11 and the second insertion part 21, the two are limited in the cavity, which is suitable for high voltage and high current application scenarios.

[0034] Specifically, the first partition 331 and the second partition 332 are spaced apart and are both parallel to the length direction of the first copper strip 1 and the second copper strip 2.

[0035] In alternative implementations, such as Figure 9 As shown, the first insert finger portion 11 is provided with a first mounting hole 111, and the second insert finger portion 21 is provided with a second mounting hole 211. The first mounting hole 111 and the second mounting hole 211 are used to achieve mechanical fixation and electrical connection between the first insert finger portion 11, the second insert finger portion 21 and the conductive component 5. Specifically, the first mounting hole 111 penetrates through the thickness direction of the first insert finger portion 11, and the second mounting hole 211 penetrates through the thickness direction of the second insert finger portion 21, and their positions are precisely aligned with the corresponding conductive female on the conductive component 5.

[0036] In the above embodiments, the first mounting hole 111 and the second mounting hole 211 respectively provided on the first insertion finger portion 11 and the second insertion finger portion 21 provide mounting positions for the conductive component 5. Compared with the conductive component 5 contacting the two insertion fingers by abutting, a more efficient and reliable bidirectional electrical connection can be achieved.

[0037] The first mounting hole 111 and the second mounting hole 211 can be circular, elliptical or polygonal, and the appropriate shape can be selected according to the actual assembly requirements.

[0038] In alternative implementations, such as Figure 10 and Figure 11 As shown, the conductive component 5 includes a first conductive female connector 51, a second conductive female connector 52, a first conductive fastener 53, and a second conductive fastener 54. Both the first conductive female connector 51 and the second conductive female connector 52 are installed in the insulating base 4. The first conductive female connector 51 has a first insertion hole 5121, and the first conductive fastener 53 is connected between the first conductive female connector 51 and the first insertion finger 21. The second conductive female connector 52 has a second insertion hole 5221, and the second conductive fastener 54 is connected between the second conductive female connector 52 and the second insertion finger 21.

[0039] Through the above structural design, the insertion part of the first copper strip 1 and the second copper strip 2 can be connected to the corresponding conductive female head through conductive fasteners, so that the first conductive female head 51 and the second conductive female head 52 can be set facing each other in the direction parallel to the length of the two copper strips, reducing the space occupied by the two conductive female heads in the width direction of the copper strips, and avoiding the micro-motion wear problem caused by gold finger insertion and removal in the prior art.

[0040] Both the first conductive female connector 51 and the second conductive female connector 52 are metal conductive terminal structures, preferably made of copper alloy material with good conductivity and mechanical strength. The first insertion hole 5121 on the first conductive female connector 51 and the second insertion hole 5221 on the second conductive female connector 52 are arranged to open in the same direction, so as to facilitate the simultaneous completion of dual-channel electrical connection when the board 6 is inserted.

[0041] The inlet ends of both the first insertion hole 5121 and the second conductive female connector 52 can be flared, with the diameter of the inlet end gradually decreasing from the outside to the inside along its axial direction, thereby reducing the difficulty of connecting the board.

[0042] Furthermore, the first conductive fastener 53 is a conductive screw or rivet, etc., one end of which forms an electrical connection with the first conductive female head 51, and the other end extends into the corresponding first mounting hole 111 on the first insert finger portion 11. Mechanical fixing and low-impedance electrical connection are achieved through threaded engagement or interference fit. Similarly, the second conductive fastener 54 firmly connects the second conductive female head 52 to the second mounting hole 211 on the second insert finger portion 21, thereby establishing a complete current path from the second copper strip 2 through the second insert finger portion 21, the second conductive fastener 54 to the second conductive female head 52.

[0043] In alternative implementations, such as Figure 12 As shown, the first conductive female connector 51 includes a first connecting portion 511 for achieving electrical connection and mechanical fixation. The first connecting portion 511 is located at one end of the first conductive female connector 51 and is constructed as a polyhedral structure to adapt to the installation space and improve connection adaptability. Specifically, a plurality of first mounting surfaces 5111 are evenly distributed along the circumference of the outer peripheral surface of the first connecting portion 511. Each first mounting surface 5111 is symmetrically arranged around the central axis of the first connecting portion 511. Each first mounting surface 5111 is provided with a first connecting hole 5112 for cooperating with the first conductive fastener 53 to connect the first conductive female connector 51 to the first insertion finger portion 11.

[0044] By designing the first connecting part 511 as a polygonal cross-section (e.g., quadrilateral, hexagonal, or octagonal) with multiple first mounting surfaces 5111, not only is the contact stability between it and the insulating base 4 enhanced, but the first conductive female head 51 also has multiple mounting angles. Since each first mounting surface 5111 is provided with a first connecting hole 5112, it is not necessary to distinguish its mounting direction when installing the first conductive female head 51, which improves the installation flexibility, facilitates the operation of installers, and reduces the assembly difficulty.

[0045] For example, such as Figure 12 As shown, the first mounting surface 5111 is configured as four, so the first conductive female head 51 has four mounting angles, each angle differing by 90°.

[0046] The first connecting hole 5112 can be a threaded hole. The first conductive fastener 53 passes through the first insert finger 11 and the cover 32, extends into the insulating seat 4, and is screwed into the first connecting hole 5112.

[0047] In alternative implementations, such as Figure 12 As shown, the first conductive female connector 51 further includes a first plug-in portion 512 located at the other end of the first conductive female connector 51. The first plug-in portion 512 is integrally formed or fixedly connected to the first connecting portion 511 and extends axially to realize electrical connection with the external board 6. The center of the first plug-in portion 512 is provided with a first plug-in hole 5121 extending through it axially. The first plug-in hole 5121 is used to receive and contact the corresponding plug on the board 6 to establish a stable electrical path.

[0048] To improve the positioning accuracy of the first conductive female connector 51 during installation and its structural stability during operation, and to prevent it from rotating circumferentially or moving axially within the insulating base 4, such as... Figure 12 As shown, a first limiting groove 5122 is provided on the outer peripheral surface of the first insertion part 512. The first limiting groove 5122 is a structure formed by radial recess, preferably an annular groove or a polygonal groove.

[0049] Accordingly, a first limiting pin is provided inside the insulating base 4. The first limiting pin is detachably connected to the insulating base 4. After the first conductive female head 51 is installed inside the insulating base 4, the first limiting pin can be inserted into the insulating base 4 and extend into the first limiting groove 5122 to form a mechanical limiting fit. Through the above limiting fit relationship, the position of the first conductive female head 51 relative to the insulating base 4 can be effectively constrained. Especially when subjected to insertion and extraction forces, it can still cooperate with the first conductive fastener 53 to maintain the stability of the position of the first conductive female head 51, and at the same time, it avoids the first conductive fastener 53 bearing the insertion and extraction forces alone, thus enhancing the conductivity stability.

[0050] Of course, the aforementioned first limiting pin can also be connected by screws or other fasteners.

[0051] Similarly, the structure of the second conductive female connector 52 is the same as that of the first conductive female connector 51. It includes a second connecting part 521. The outer peripheral surface of the second connecting part 521 is provided with a plurality of second mounting surfaces 5211 arranged circumferentially along the second connecting part 521. Each second mounting surface 5211 is provided with a second connecting hole 5212 for connecting the second conductive fastener 54.

[0052] The advantage of the above-mentioned setup is that it improves the installation flexibility of the second conductive female connector 52, making it easier for installers to operate and reducing assembly difficulty.

[0053] Accordingly, such as Figure 4 As shown, the second conductive female connector 52 also includes a second plug-in portion 522 connected to the second connecting portion 521. The second plug-in portion 522 has a second plug-in hole 5221. The outer surface of the second plug-in portion 522 is provided with a second limiting groove 5222. The insulating base 4 is provided with a second limiting pin 42 that extends into the second limiting groove 5222.

[0054] The above configuration can effectively constrain the position of the second conductive female head 52 relative to the insulating base 4, and also prevent the second conductive fastener 54 from directly bearing the insertion and removal, thereby enhancing the conductivity stability.

[0055] In alternative implementations, such as Figure 2 As shown, the top of the insulating base 4 is provided with a guide groove 41. The entrance end of the guide groove 41 is funnel-shaped, and its opening size gradually decreases from the outside to the inside. The frame 8 may be provided with a receiving groove opposite to the guide groove 41, and the board 6 can be finally limited into the receiving groove to realize the installation of the board 6.

[0056] like Figure 2 As shown, the insulating base 4 not only provides electrical isolation and physical protection for the conductive components 5, enhancing the safety and electromagnetic compatibility of the device, but also integrates a guide groove 41 on its top, providing mechanical guidance and positioning for the insertion of the board 6. This integrated design organically combines insulation and mechanical guidance functions, reducing the space required for additional guide structures, allowing for a more compact chassis structure and improved space utilization.

[0057] When the power supply device is installed on the rack 8, at least one side of the insulating base 4 will directly face or be in contact with the metal surface of the rack 8. Since the first conductive female connector 51 and the second conductive female connector 52 in the conductive assembly 5 are made of conductive material, and part of their structure may be exposed from the side of the insulating base 4 or arranged close to the edge of the rack 8, there is a risk of accidental contact with the rack 8 leading to short circuit, leakage, or grounding failure without additional insulation measures.

[0058] To address the aforementioned safety hazards, in an optional embodiment, the power supply device further includes an insulating sheet 7. The insulating sheet 7 is a non-conductive component with a predetermined thickness and mechanical strength, typically made of heat-resistant, flame-retardant engineering plastics or ceramic composite materials with good dielectric properties, such as polyamide, polybutylene terephthalate, or epoxy glass cloth.

[0059] The shape of the insulating sheet 7 can match the contour of the insulating base 4 facing the frame 8, and can completely cover all potentially exposed conductive areas on that side. The insulating sheet 7 can be fixed to the corresponding surface of the insulating base 4 by means of snap-fit, adhesive, screw or embedding, ensuring that it will not shift or fall off under vibration, insertion and removal operations or long-term operation conditions.

[0060] Specifically, such as Figure 4 As shown, the insulating base 4 is provided with through holes for installing the first conductive female head 51 and the second conductive female head 52. The insulating sheet 7 is provided with a boss 71 for extending into the through hole. The boss 71 can not only position the insulating sheet 7, but also provide auxiliary limiting for the two conductive female heads to ensure that the two conductive female heads will not fall out of the insulating base 4.

[0061] A second aspect of the present invention provides a chassis, such as Figure 13 As shown, the chassis provided in the second aspect of the present invention includes a frame 8 and the aforementioned power supply device, wherein the frame 8 is connected to the insulating base 4.

[0062] The chassis provided in the second aspect of the present invention includes the power supply device provided in the first aspect of the present invention, thereby having all the beneficial effects of the power supply device provided in the first aspect of the present invention.

[0063] Specifically, the frame 8 can be connected to the bottom of the insulating base 4 via screws or other connectors.

[0064] In alternative implementations, such as Figures 13 to 16 As shown, the chassis also includes a board 6, which is movably connected to a floating seat 62. The floating seat 62 is provided with a plug 64, which is inserted into the first plug hole 5121 and the second plug hole 5221.

[0065] When board 6 is inserted into the chassis, floating seat 62 moves accordingly, aligning plug 64 with and inserting it into the first and second sockets 5121, thereby establishing a power transmission path. Because floating seat 62 has a degree of freedom of movement, even if there is a slight misalignment or installation deviation between board 6 and the power supply device during the insertion process, floating seat 62 can compensate for this deviation through self-adjustment, ensuring that plug 64 can be smoothly and accurately inserted into the corresponding sockets, avoiding problems such as damage to the plug, poor contact, or increased insertion damage caused by forced insertion.

[0066] In alternative implementations, such as Figures 14 to 16 As shown, the board 6 also includes a board body 61, a limiting component 63, and a plug 64; the floating seat 62 is rotatably engaged with the board body 61; one of the board body 61 and the floating seat 62 is fixedly connected to the limiting component 63, and the other is provided with a limiting hole group, the limiting component 63 extends into the limiting hole group and there is a gap between it and the limiting hole group; the plug 64 is connected to the floating seat 62.

[0067] In the board 6 provided in the above embodiment, by setting the floating seat 62 and the board body 61 to a rotational fit, and combining the clearance fit between the limiting component 63 and the limiting hole group, when the board 6 is inserted into the rack 8, even if there is an initial alignment deviation, the floating seat 62 can rotate relative to the limit component 63 within the tolerance range, thereby guiding the plug 64 to dock smoothly, solving the contact failure problem caused by the deformation of the chassis in the Z-axis direction.

[0068] It is understandable that the Z-axis mentioned above refers to the height direction of the board.

[0069] Furthermore, the aforementioned structure eliminates the reliance on elastic elements in traditional floating connectors to achieve floating functionality, avoiding issues such as fatigue, aging, and performance degradation that occur when elastic materials are subjected to long-term pressure, thus ensuring the long-term stability and durability of the floating function. Compared to the stringent mechanical precision requirements of backplane direct-insertion connections, this structure reduces the alignment difficulty during assembly and maintenance, improves the maintainability and operational stability of the equipment in high-frequency insertion and removal scenarios, and is particularly suitable for semiconductor automated testing equipment with high reliability requirements.

[0070] In alternative implementations, such as Figure 16 As shown, the board body 61 includes a fixed base 611, and the fixed base 611 is provided with a fixed shaft 6111. The axial direction of the fixed shaft 6111 is parallel to the thickness direction of the board 6. The floating seat 62 is sleeved on the fixed shaft 6111 through a rotating hole, thereby realizing a rotational engagement with the fixed shaft 6111. The above-mentioned rotational engagement allows the floating seat 62 to rotate freely within a certain angle range around the axis of the fixed shaft 6111, providing rotational freedom for the spatial position adjustment of the plug 64 during the docking process.

[0071] Furthermore, one of the fixed seat 611 and the floating seat 62 is fixedly connected to the limiting component 63, while the other is provided with a limiting hole group. The limiting hole group consists of one or more through holes with a predetermined geometric shape (such as a circle, ellipse, or polygon), evenly distributed on an arc-shaped trajectory centered on the fixed axis 6111. One end of the limiting component 63 is fixed to the fixed seat 611 or the floating seat 62, and the other end extends into the limiting hole group, maintaining a predetermined gap with the hole wall to form a clearance fit structure.

[0072] by Figure 16 For example, the floating seat 62 is fixedly connected to the limiting component 63, and the fixed seat 611 is provided with a group of limiting holes.

[0073] In alternative implementations, such as Figure 14 As shown, the board body 61 includes a first side plate 65 and a second side plate 66 arranged opposite to each other along the thickness direction of the board. The two are arranged in parallel and together form the main support frame of the board. A preset distance is maintained between the first side plate 65 and the second side plate 66 to accommodate internal electronic components, wiring channels and mechanical connection components, while providing sufficient structural strength to resist bending moment and shear force during insertion and removal.

[0074] Furthermore, the fixed base 611 serves as the rotational support foundation for the floating base 62. Its two ends are firmly connected to the first side plate 65 and the second side plate 66, respectively, through methods such as screw fastening, riveting, or integral molding. This secures the fixed base 611 stably between the two side plates, forming a bridging installation structure. This connection method not only enhances the rigidity and stability of the overall structure but also ensures that the fixed base 611 does not shift or twist under stress, providing a reliable rotational axis foundation for the subsequent precise rotational movement of the floating base 62.

[0075] In alternative implementations, such as Figure 16 As shown, the floating seat 62 includes a floating part 621 and a connecting part 622, which can be integrally formed to ensure structural strength and motion stability. The floating part 621 is disposed in the receiving space between the first side plate 65 and the second side plate 66 of the board body 61. The above layout effectively utilizes the longitudinal space inside the board, avoids adding extra external dimensions, and is conducive to the miniaturization and modular integration of the device.

[0076] The floating part 621 is provided with a rotating hole, which forms a rotational engagement with the fixed shaft 6111, allowing the floating seat 62 to rotate within a certain angle range around the axis of the fixed shaft 6111. The floating part 621 is also fixedly connected to the limiting component 63. Specifically, one end of the limiting component 63 is fixed to the floating part 621, and the other end extends into the limiting hole group on the fixed seat 611, maintaining a preset gap between it and the hole wall of the limiting hole group.

[0077] When the board 6 is inserted into the chassis, if there is an initial positional deviation between the first plug hole 5121 and the second plug hole 5221 on the power supply device and the plug 64, the floating seat 62 can automatically adjust its spatial posture through the above-mentioned rotational degrees of freedom, guide the plug 64 to be smoothly aligned and complete the insertion action, thereby realizing a flexible docking mechanism of "aligning first and then connecting".

[0078] Additionally, the connecting portion 622 extends outward from the floating portion 621 and is exposed in the external area of ​​the board for mounting the plug 64. The plug 64 is fixedly connected to the end of the connecting portion 622 away from the floating portion 621, with its electrical connection end exposed outward to facilitate electrical contact with the first plug hole 5121 and the second plug hole 5221 in the power supply device.

[0079] In alternative implementations, such as Figure 16 and Figure 17 As shown, the limiting component 63 includes a first limiting member 631 that is fixedly connected to the floating seat 62, and correspondingly, a first limiting hole 6112 matching it is provided on the fixing seat 611 of the board body 61.

[0080] The first limiting member 631 can be a rigid structure such as a pin, a protrusion, a screw, or an integrally formed positioning post, preferably a cylindrical structure. The first limiting hole 6112 is a through hole or blind hole opened on the fixed base 611, and its shape is adapted to the first limiting member 631, usually a circular hole. In particular, the diameter of the first limiting hole 6112 is larger than the outer diameter of the first limiting member 631, thereby forming a circumferentially uniform or asymmetrically distributed gap between the two. The gap constitutes a degree of freedom space that allows the floating base 62 to rotate slightly within a certain range.

[0081] In alternative implementations, such as Figure 16 and Figure 17 As shown, the limiting component 63 further includes a second limiting member 632 fixedly connected to the floating seat 62. Correspondingly, the fixed seat 611 on the board body 61 is provided with a second limiting hole 6113, and the diameter of the second limiting hole 6113 is larger than the outer diameter of the second limiting member 632, so that the floating seat 62 can rotate relative to the board body 61 within a certain range.

[0082] Furthermore, the second limiting member 632 and the second limiting hole 6113, combined with the aforementioned first limiting member 631 and the first limiting hole 6112, can effectively constrain the degrees of freedom of the floating seat 62. At the same time, since the first limiting member 631 and the second limiting member 632 are subjected to force together, it ensures the necessary room for movement to achieve deviation compensation, and also prevents connection instability caused by excessive shaking.

[0083] In alternative implementations, such as Figure 16 As shown, the floating seat 62 is provided with a third limiting hole 623, and the board body 61 also includes a limiting post 6121 that extends into the third limiting hole 623 and has a gap between it and the third limiting hole 623. The length direction of the limiting post 6121 is perpendicular to the rotation axis of the floating seat 62.

[0084] Since there is a gap between the third limiting hole 623 and the limiting post 6121, the gap is used to ensure that the floating seat 62 can rotate relative to the board body 61 while limiting the maximum amount of rotation of the floating seat 62.

[0085] In actual use or maintenance, operators may neglect to disassemble the limiting component 63 and fail to restore it in time, causing the original limiting structure to fail and affecting the normal working performance of the floating seat 62. By adding a third limiting hole 623 and a limiting post 6121 as an independent mechanical limiting pair, even if the limiting component 63 is temporarily removed or missing, the floating seat 62 can still maintain basic positional constraint capability through the above-mentioned redundant structure, avoiding complete loss of floating limiting function and significantly reducing the risk of connection failure or hardware damage caused by human error.

[0086] Specifically, the aforementioned limiting post 6121 is arranged parallel to the first side plate 65 and the second side plate 66.

[0087] In alternative implementations, such as Figure 16 As shown, the board body 61 also includes a wire lead-out seat 612 connected between the first side plate 65 and the second side plate 66, and the limiting post 6121 can be fixed on the wire lead-out seat 612.

[0088] Specifically, the board body 61 also includes a wire extending from the outlet 6122 of the wire lead-out seat 612 and connected to the plug 64. The length of the wire between the outlet 6122 and the plug 64 is greater than the straight-line distance between them. In other words, the wire is in a non-tensioned state in this section, with a certain slack or a preset bending shape, such as a flexible routing method like a U-shape, S-shape, or wave shape. This structural design allows the wire to have sufficient deformation capacity in space.

[0089] During the insertion and docking of board 6 into the chassis, the floating seat 62, guided by the clearance fit between the limiting component 63 and the limiting hole group, may undergo slight rotation or offset relative to the board body 61 to compensate for the positional deviation between the plug 64 and the corresponding socket on the power supply device. During this dynamic adjustment, the floating seat 62 causes relative movement of the plug 64 connected to it, and the wires connecting the plug 64 also experience slight stretching or positional adjustment. This design prevents the wires from experiencing excessive mechanical stress or being forcibly straightened during adjustment.
