Description

Technical Field

[0001] This application relates to the field of server technology, and more particularly to an electronic device expansion card bracket and an electronic device. Background Technology

[0002] Currently, expansion cards in electronic devices, such as PCIe cards (Peripheral Component Interconnect Express) on servers, typically employ a physical deployment where one end of the PCIe card and the Riser card (PCIe expansion adapter card) are connected via gold fingers, while the other end remains free. This method is prone to sagging or deformation under its own weight, equipment vibration, or additional stress during transportation, resulting in weak structural support and poor reliability. Misalignment of the free end directly affects the gold finger connection, leading to uneven pressure distribution or poor contact with the slot. This poor contact can easily cause communication link failures, manifesting as unstable signal transmission, bandwidth loss, or even link interruption, severely impacting system stability and data transmission performance. Furthermore, PCIe cards and Riser cards are mostly installed and fixed with screws, requiring each screw to be tightened or loosened individually during installation and removal, a cumbersome process with low efficiency. Summary of the Invention

[0003] This application provides an electronic device expansion card holder and an electronic device to at least solve the problem of poor structural reliability of expansion card deployment on servers in related technologies.

[0004] This application provides an electronic device expansion card holder, comprising: a main body; a first connecting portion located at a first end of the main body, the first connecting portion having a first connecting structure for mating with one end of an expansion card; a second connecting portion located at a second end of the main body opposite to the first end, the main body, the first connecting portion, and the second connecting portion together forming a receiving area for accommodating the expansion card, the second connecting portion having a second connecting structure for mating with the other end of the expansion card; and a limiting member disposed on the first connecting portion and / or the second connecting portion, and at least a portion of the limiting member being movably disposed relative to the first connecting portion and / or the second connecting portion, the expansion card being locked to the first connecting portion and / or the second connecting portion by the limiting member.

[0005] This application also provides an electronic device, including an expansion card and the aforementioned electronic device expansion card holder. The expansion card includes an expansion device and an adapter device, both of which are detachably mounted on the electronic device expansion card holder.

[0006] In this application, a first connecting portion and a second connecting portion are respectively provided at both ends of the main body. These three portions are used to install and accommodate an expansion card. The first and second connecting portions each have a first connecting structure and a second connecting structure. When the expansion card is installed into the accommodating area, both ends of the expansion card mate with the first and second connecting structures, respectively, forming a preliminary limiting relationship. At this time, the limiting effect of the first and second connecting structures on the expansion card is relatively small, and the expansion card is still in a state where it can wobble or even fall off. Since the first and second connecting structures only play a preliminary limiting role, this embodiment also provides a limiting member. The limiting member provides a locking and limiting relationship for the expansion card after preliminary installation. That is, when the expansion card is placed in the container area, forming a preliminary engagement relationship between the expansion card and the first and second connecting structures, the limiting member blocks the path of the expansion card out of the accommodating area, thereby preventing the expansion card from being disassembled and locking it to the bracket, preventing disassembly. With the above-described configuration, since both ends of the expansion card are supported by the first and second connecting structures respectively, both ends of the expansion card can be effectively supported, preventing one end from sinking due to vibration or other factors. This ensures the stability and reliability of the expansion card after installation, thereby guaranteeing the reliability of the connection at the gold fingers, ensuring system stability and data transmission performance. Furthermore, compared to the traditional screw installation method, the limiting component in this embodiment can adopt a quick-release structure, enabling rapid switching between locking and unlocking, thus achieving the purpose of quick installation and removal of the expansion card and facilitating maintenance operations.

[0027] 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.

[0028] To address the issue of poor structural reliability in the deployment of expansion cards on servers in related technologies, this application provides an electronic device expansion card bracket and an electronic device.

[0029] like Figures 1 to 15An electronic device expansion card holder is shown, comprising a main body 10, a first connecting portion 20, a second connecting portion 30, and a limiting member. The first connecting portion 20 is located at a first end of the main body 10 and has a first connecting structure for mating with one end of an expansion card 70. The second connecting portion 30 is located at a second end of the main body 10 opposite to the first end. The main body 10, the first connecting portion 20, and the second connecting portion 30 together form a receiving area for accommodating the expansion card 70. The second connecting portion 30 has a second connecting structure for mating with the other end of the expansion card 70. The limiting member is disposed on the first connecting portion 20 and / or the second connecting portion 30, and at least a portion of the limiting member is movably disposed relative to the first connecting portion 20 and / or the second connecting portion 30. The expansion card 70 is locked to the first connecting portion 20 and / or the second connecting portion 30 by the limiting member.

[0030] In this embodiment, a first connecting part 20 and a second connecting part 30 are respectively provided at both ends of the main body 10. The three are used to install and accommodate the expansion card 70. The first connecting part 20 and the second connecting part 30 have a first connecting structure and a second connecting structure, respectively. When the expansion card 70 is installed into the accommodating area, the two ends of the expansion card 70 are respectively connected to the first connecting structure and the second connecting structure. The two ends of the expansion card 70 form a preliminary limiting relationship with the first connecting structure and the second connecting structure. At this time, the limiting effect of the first connecting structure and the second connecting structure on the expansion card 70 is small, and the expansion card 70 is still in a state where it can shake or even fall off. Since the first and second connecting structures only serve as preliminary limiting mechanisms, this embodiment also includes a limiting component. The limiting component engages with the initially installed expansion card 70, locking it in place. That is, when the expansion card 70 is placed in the container area, forming a preliminary engagement between the expansion card 70 and the first and second connecting structures, the limiting component blocks the path of the expansion card 70 out of the container area. This prevents the expansion card 70 from being disassembled, locking it to the bracket and preventing it from being disassembled. With the above-described configuration, since both ends of the expansion card 70 are supported by the first and second connecting structures respectively, both ends of the expansion card 70 can be effectively supported, preventing one end from sinking due to vibration or other factors. This ensures the stability and reliability of the expansion card 70 after installation, thereby guaranteeing the reliability of the connection at the gold fingers, ensuring system stability and data transmission performance. In addition, compared with the traditional screw installation method, the limiting component in this embodiment can adopt a quick-release structure, which can realize the quick switching between locking and unlocking of the limiting component, thereby achieving the purpose of quick installation and removal of the expansion card 70, facilitating maintenance and other operations.

[0031] This embodiment uses a server as an example for illustration. Accordingly, the expansion card bracket of the electronic device is the expansion card bracket of the server. The expansion card 70 includes two parts: an expansion device 71 and an adapter device 72. The expansion device 71 is a PCIe card, and the adapter device 72 is a Riser card. Of course, the bracket of this embodiment can also be applied to other electronic devices as needed, such as routers, switches, etc. Accordingly, the expansion card 70 can also be other types of devices.

[0032] Optionally, the number of limiting members can be set as needed, and there can be one or more. In this embodiment, there are multiple limiting members. Both the first connecting part 20 and the second connecting part 30 are provided with limiting members, or more specifically, there are two, which are located at the first connecting part 20 and the second connecting part 30 respectively. The two ends of the expansion device 71 of the expansion card 70 are respectively mated with the first connecting part 20 and the second connecting part 30, and locked with the limiting member at the first connecting part 20. The two ends of the adapter device 72 of the expansion card 70 are respectively mated with the first connecting part 20 and the second connecting part 30, and locked with the limiting member at the second connecting part 30. That is to say, both ends of the expansion device 71 and the adapter device 72 are mated with the first connecting structure and the second connecting structure, so that both ends of the expansion device 71 and the adapter device 72 can be effectively supported, ensuring the overall stability of the expansion card 70. The setting of the two limiting members allows the locking of the expansion device 71 and the adapter device 72 to be carried out separately and independently, so that the expansion device 71 and the adapter device 72 do not affect each other. When it is only necessary to remove the expansion device 71, only the corresponding limiting member needs to be operated, without affecting the adapter device 72.

[0033] Optionally, the limiting member can be configured in various ways. For example, the limiting member can be rotatably connected to the first connecting part 20 or the second connecting part 30. In this case, the limiting member can adopt a flip-plate structure. When the limiting member rotates, it can switch between a position that blocks the disassembly path of the expansion device 71 and a position that avoids the disassembly path of the expansion device 71, thereby achieving locking after the expansion device 71 is installed and unlocking during disassembly, thus realizing the installation and fastening of the expansion device 71 and the avoidance of disassembly. Alternatively, the limiting member can have a deformable part 431. The deformable part 431 is deformable and can deform under external force. It is a component that cooperates with the adapter 72. In this case, the deformable part 431 can be in the form of a spring or similar material. When the deformable part 431 is not deformed, it is in its initial position, abutting against the adapter 72, thus limiting the adapter 72 and preventing its disassembly. When the adapter 72 needs to be disassembled, the person moves the deformable part 431, causing it to deform. After deformation, the deformable part 431 avoids the disassembly path of the adapter 72, allowing it to be disassembled. Of course, the specific locking and limiting form of the limiting member is not limited to the above-described setting in this embodiment; other structural forms can also be used, as long as they can cooperate with the corresponding device of the expansion card 70 to prevent the device from being disassembled.

[0034] like Figures 1 to 3 As shown, in this embodiment, the main body 10, the first connecting part 20, and the second connecting part 30 form a semi-enclosed structure. Since the first connecting part 20 and the second connecting part 30 are located at both ends of the main body 10, the main body 10 has an opening side on the side where the first connecting part 20 and the second connecting part 30 are not provided, thus forming an installation opening on this side. The expansion card 70 is mainly installed into the receiving area from this installation opening. The adapter 72 enters the receiving area from the installation opening as a whole and is slightly tilted. One end of the adapter 72 is initially installed on one of the first connecting structure and the second connecting structure, and then the other end cooperates with the other of the first connecting structure and the second connecting structure. Finally, it is locked by the limiting member. The expansion device 71 is installed into the receiving area in a roughly parallel direction along the installation opening and is locked by the limiting member after installation.

[0035] like Figure 4 and Figure 5As shown, in this embodiment, the first connecting part 20 includes a first connecting body 21 and a first positioning part 22. The first connecting body 21 is connected to the main body 10. The first connecting body 21 is the main part of the first connecting part 20. It cooperates with the main body 10 to jointly form an accommodating area. The first connecting body 21 has a third end and a fourth end facing the accommodating area. That is, the third end and the fourth end are the two opposite ends inside the accommodating area. The expansion device 71 of the expansion card 70 is inserted into the accommodating area along the direction from the third end to the fourth end, so that the line between the third end and the fourth end is the short side of the accommodating area, and the third end is closer to the mounting opening than the fourth end. The line between the first end and the second end is the long side of the accommodating area. A first positioning part 22, serving as at least part of the first connecting structure, is provided at the third end and / or the fourth end. In this embodiment, the first positioning part 22 is provided at both the third end and the fourth end. Thus, when the expansion device 71 is installed in the receiving area, it can be guided and positioned at the first positioning part 22, thereby enabling the first positioning part 22 to guide and position the installation of the expansion device 71, ensuring the stable and reliable installation of the expansion device 71. At the same time, the limiting member includes a first limiting member 41 located at the third end. Since the first limiting member 41 is located at the installation opening, when the expansion device 71 is installed in the receiving area, the position of the first limiting member 41 can be switched, so that the expansion device 71 and the first limiting member 41 form a locking and limiting engagement relationship, thereby achieving the locking of the expansion device 71.

[0036] It should be noted that the expansion device 71 includes two parts: a main device and a connecting piece. The main device is the main part, and the connecting piece is the part that cooperates with the first connecting body 21. The connecting piece has an L-shaped structure. The first side of the L-shape is connected to the main device, and the second side of the L-shape is bent away from the main device.

[0037] In this embodiment, there are multiple first positioning parts 22, and first positioning parts 22 are provided at both the third and fourth ends. The number and structure of the first positioning parts 22 at each end can also be set as needed. In this embodiment, the first positioning part 22 at the fourth end is in the form of a guide groove. The guide groove extends along the installation direction of the expansion device 71. When the expansion device 71 is installed into the receiving area from the third end to the fourth end, the free end of the first side of the connecting piece can be inserted into the guide groove and initially limited in the guide groove, thereby achieving initial fixation of that end. At the same time, in this embodiment, there are two first positioning structures 60 at the third end. The two first positioning structures 60 are a protrusion and a through hole, respectively. Correspondingly, the second side of the connecting piece is also provided with holes and protrusions that cooperate with the protrusion and through hole. When the free end of the first side is inserted into the guide groove, the holes and protrusions on the second side also cooperate with the protrusion and through hole, respectively, so that both ends of the connecting piece are initially limited by the first positioning parts 22, completing the initial installation of the expansion device 71.

[0038] In this embodiment, the first limiting member 41 is rotatably disposed at the third end and located on the outer side of the third end away from the receiving area. Specifically, a pivot hole 25 is provided on the outer side of the third end, that is, the side at the outer edge of the mounting opening. A pivot is also provided in conjunction with the pivot. The pivot passes through the first limiting member 41 and the pivot hole 25, so that the first limiting member 41 can be rotatably engaged with the first connecting body 21 through the pivot. When the expansion device 71 is installed, the first limiting member 41 is flipped so that the first limiting member 41 is separated from the outer side of the third end. The first limiting member 41 avoids the insertion of the second side of the connecting piece. After the expansion device 71 is initially installed, the first limiting member 41 is flipped so that the first limiting member 41 blocks the disassembly path of the expansion device 71. More specifically, it blocks the second side of the connecting piece, so that the first limiting member 41 obstructs the disassembly path of the expansion device 71 and prevents the expansion device 71 from being disassembled from the first connecting part 20, thereby achieving a locking effect on the expansion device 71 and making it impossible to disassemble the expansion device 71.

[0039] like Figures 10 to 12 As shown, in this embodiment, the first limiting member 41 further includes a locking part 42. The locking part 42 is connected to the first limiting member 41 and can be locked in place with the first connecting body 21. The locking part 42 in this embodiment is a quick-release structure, such as a hand-tightening screw, which allows for quick assembly and disassembly without the need for other tools, making it convenient and fast. In conjunction with the locking part, this embodiment provides a locking hole 26 on the first connecting body 21. The locking hole 26 and the locking part 42 can be engaged through a threaded structure. Thus, after the expansion device 71 is initially positioned, when the first limiting member 41 is flipped over, the first limiting member 41 covers the expansion device 71, and the locking part 42 aligns with the locking hole 26, allowing the locking part 42 to extend into the locking hole 26, thereby achieving a locking relationship between the locking part 42 and the first connecting body 21.

[0040] In this embodiment, the locking hole 26 is located on the outer side of the first connecting body 21 away from the receiving area. Correspondingly, the first limiting member 41 has a bent section. The bent section bends from the side where the mounting opening is located to the outer side of the first connecting body 21. The locking part 42 is located at the bent section, so that the position of the locking part 42 can be adapted to the locking hole 26. At the same time, the locking part 42 can also be located at the end face of the bracket, which facilitates operation by personnel and reduces the impact on the width of the bracket.

[0041] Optionally, a clearance hole can be provided on the first limiting member 41 as needed. The clearance hole is designed to cooperate with the protrusion, so that when the first limiting member 41 flips to lock the connecting piece, it can cooperate with the protrusion to avoid the protrusion of the protrusion affecting the flipping of the first limiting member 41 to the correct position, and ensure that the first limiting member 41 can be tightly cooperated with the first connecting body 21 when it is flipped to lock.

[0042] To facilitate the external connection of the expansion device 71, this embodiment provides a relatively large docking opening 27 on the first connecting body 21. The docking opening 27 extends from the third end to the fourth end, so that the interface at the end of the expansion device 71 can be exposed through the docking opening 27, thereby facilitating the connection of adapter devices, wire terminals and other devices, and realizing the effect of external connection of the expansion card 70.

[0043] like Figure 4 and Figure 5 As shown, in this embodiment, the first connecting part 20 includes conductive foam 24, which is provided inside the receiving area and / or on the top surface of the first connecting body 21. In this embodiment, conductive foam 24 is provided on both the top surface of the first connecting body 21 and the inner side of the first connecting body 21 facing the receiving area, and multiple conductive foams 24 are provided on the inner side. In this embodiment, one conductive foam 24 is provided above and below the mating opening 27, thereby providing electromagnetic shielding, preventing mutual interference between signals, and ensuring stability during use. The surface of the first connecting body 21 is treated with conductive anodizing.

[0044] like Figure 5 , Figure 14 and Figure 15 As shown, in this embodiment, the first connecting portion 20 further includes a first mounting portion 23, which serves as at least part of the first connecting structure. The first mounting portion 23 is located on the inner side of the fourth end, and it can be mated with the adapter 72 of the expansion card 70 for mounting the adapter 72. Specifically, in this embodiment, a mounting groove is provided on the inner side of the fourth end, with the opening of the mounting groove facing the second end. The mounting groove serves as the first mounting portion 23. Thus, when installing the adapter 72, one end of the adapter 72 can be inserted into the mounting groove, thereby achieving the initial installation of one end of the adapter 72.

[0045] Overall, the first connection structure in this embodiment includes a first positioning part 22 and a first mounting part 23, which are used for the initial installation of the expansion device 71 and the adapter device 72, respectively. Of course, the first connection structure can also be adjusted as needed, and other structures can be added as needed to further limit the installation of the expansion card 70.

[0046] like Figures 6 to 9 As shown, in this embodiment, the second connecting part 30 includes a second connecting body 31 and a second positioning part 32. The second connecting body 31 is connected to the main body 10. The second connecting body 31 is the main part of the second connecting part 30. It cooperates with the main body 10 to form an accommodating area. Correspondingly, the limiting member includes a second limiting member 43. The second limiting member 43 is connected to the second connecting body 31, so that the second limiting member 43 achieves a cooperating relationship with the main body 10 through the second connecting body 31. The second limiting member 43 is used to lock and limit the cooperation with the adapter 72. When the adapter 72 of the expansion card 70 is installed in the accommodating area, after a preliminary snap-fit ​​cooperation is achieved between one end of the adapter 72 and the first mounting part 23, the other end is pushed further inward. At this time, the other end of the adapter 72 can gradually approach the second limiting member 43, thereby achieving a limiting cooperation with the second limiting member 43. The second limiting member 43 achieves the locking effect on the adapter 72, so that the adapter 72 is stably installed in the accommodating area. The second positioning part 32 is connected to the second connecting body 31 and / or the main body 10. In this embodiment, the second positioning part 32 is connected to the main body 10 and to the top lower surface of the main body 10. The second positioning part 32 has a limiting groove 321 as at least part of the second connecting structure. The limiting groove 321 extends along the mounting direction of the expansion device 71 of the expansion card 70, that is, the limiting groove 321 extends along the direction from the third end to the fourth end. In this way, when the expansion device 71 is installed in the receiving area, one end of the expansion device 71 can slide into the first positioning part 22 along the mating opening 27 and connect with the second connecting body 31 and / or the main body 10. The positioning parts 22 achieve initial positioning and engagement. Simultaneously, the protruding edge of the other end of the expansion device 71 can extend into the limiting groove 321 and slide along it. At this time, the opposite sides of the limiting groove 321, i.e., the upper and lower sides, support the expansion device 71, preventing it from moving vertically and allowing it to only be inserted or removed laterally into the receiving area. This achieves initial positioning of the other end of the expansion device 71. After the initial installation of the expansion device 71, the first limiting member 41 locks it in place, preventing removal and disassembly. The limiting groove 321 supports the original free end of the expansion device 71, restricting its movement in the thickness direction and limiting vertical vibration. Furthermore, the structure of the limiting groove 321 facilitates installation of the expansion device 71, and, in conjunction with the first positioning part 22, ensures effective guidance and support for both ends of the expansion device 71. The second positioning part 32 can provide sufficient free end support for the expansion device 71, strengthen its structural strength in the module, increase its resistance to vibration, impact and other scenarios, and improve the stability and reliability of the module operation.

[0047] like Figure 7 As shown, in this embodiment, the second connecting body 31 has a support area communicating with the receiving area. The support area is opened towards the receiving area, so that when the adapter 72 is installed in the receiving area, a part of the adapter 72 can be located in the support area. At the same time, the inner wall of the support area has a support protrusion 311 as at least part of the second connecting structure. The support protrusion 311 protrudes into the support area, so that the adapter 72 can be located at the support protrusion 311, thereby forming a support fit with the support protrusion 311, and achieving effective support for the elongated adapter 72.

[0048] The second connecting body 31 in this embodiment adopts a multi-segment structure with bending, specifically including a first segment, a second segment, and a third segment that are bent and connected in sequence. The first and third segments bend in the same direction relative to the second segment, resulting in a U-shaped structure for the second connecting body 31. In this embodiment, the second connecting body 31 is located on the side of the second end of the main body 10, so that the second segment and one side of the main body 10, more specifically, the longitudinal side, form a roughly parallel structure. The first and third segments are located above and below the second segment, respectively, and both extend laterally, thus forming a support area between the first, second, and third segments. Support protrusions 311 protrude from the surfaces of the first and third segments facing the support area, allowing the support protrusions 311 on both the upper and lower sides to accommodate and support the free end of the adapter 72. Of course, the specific structural form of the second connecting body 31 can be adjusted as needed and is not limited to the structural form described in this embodiment.

[0049] like Figure 6 As shown, in this embodiment, the second connecting body 31 has a mounting recess 312, that is, a mounting recess 312 is provided on the rear side of the second segment away from the support area. Correspondingly, the second limiting member 43 includes a connecting segment and a deformable portion 431, both of which are in the form of sheets. The connecting segment is used for connection and engagement with the second connecting body 31. The shape and size of the mounting recess 312 are approximately the same as those of the connecting segment, so that the connecting segment can be installed and accommodated within the mounting recess 312, and the connecting segment does not protrude from the surface of the mounting recess 312, making the entire rear side surface of the second connecting body 31 substantially flush. The deformable part 431 is connected to the connecting section. In this embodiment, the two are connected by bending to form an L-shaped structure. The deformable part 431 extends out of the mounting recess 312 and is in the form of a spring, so that it can be deformed. In this way, the deformable part 431 can be located at the end of the adapter 72, so that it can form a limiting and locking engagement with the end of the adapter 72.

[0050] like Figures 13 to 15 As shown, in this embodiment, a snap-fit ​​protrusion 432 for engaging with the adapter 72 is provided on the side of the deformable portion 431. The snap-fit ​​protrusion 432 can engage with the snap-fit ​​position at the end of the adapter 72. When the deformable portion 431 is not deformed, it is in its initial state under its own elastic force. At this time, the side of the deformable portion 431 is close to the adapter 72, thereby forming a snap-fit ​​limiting engagement relationship between the snap-fit ​​protrusion 432 and the snap-fit ​​position on the adapter 72. The snap-fit ​​protrusion 432 hinders the adapter 72 from engaging with the adapter 72. The end detaches, thereby locking both ends of the adapter 72 in conjunction with the first mounting part 23. When it is necessary to disassemble the adapter 72, the deformation part 431 is moved to deform the deformation part 431. At this time, the deformation part 431 deforms in a direction away from the adapter 72, thereby causing the locking protrusion 432 to move in a direction away from the adapter 72 and avoid the disassembly path of the adapter 72. This allows the end of the adapter 72 to be disengaged from the second limiting member 43 and then from the receiving area, thereby realizing the disassembly of the adapter 72.

[0051] In this embodiment, the snap-fit ​​protrusion 432 has an inclined surface on the side facing the installation opening, and the inclined surface is set at an angle. In this way, when installing the adapter 72, the operator does not need to move the deformable part 431. At this time, as the adapter 72 is installed, the end of the adapter 72 will first contact the inclined surface, and then press against the inclined surface, so that the deformable part 431 will deform under the pressure of the adapter 72, and then the end of the adapter 72 can pass over the snap-fit ​​protrusion 432. Subsequently, the snap-fit ​​protrusion 432 will automatically recover under the elastic force of the deformable part 431, which further facilitates the installation of the adapter 72.

[0052] like Figure 8As shown, in this embodiment, a positioning and fitting structure is provided between the second positioning part 32 and the main body part 10, and the two are positioned and connected through the positioning and fitting structure. Specifically, one of the second positioning part 32 and the main body part 10 has a plurality of positioning posts 322 for positioning and fitting. In this embodiment, two positioning posts 322 are provided on the upper surface of the second positioning part 32, and correspondingly, two holes are provided on the main body part 10. The two positioning posts 322 are not the same size, and the size of the hole matches the size of the corresponding positioning post 322. In this way, a one-to-one matching relationship is formed between the positioning post 322 and the hole. When the installation direction of the second positioning part 32 is correct, the limiting groove 321 on it faces the container area, and the positioning post 322 can be inserted into the hole of the corresponding size, thereby realizing the installation positioning and fitting. However, when the installation direction of the second positioning part 32 is incorrect, the positioning hole and the hole of the corresponding size are misaligned, which causes the second positioning part 32 to be unable to be fixed, reminding the assembly personnel to make corrections. This can ensure that the second positioning part 32 is installed accurately and reliably.

[0053] In this embodiment, the limiting slide 321 has a side opening, with its upper, lower, and opposite sides all being shielded. The inner wall of the limiting slide 321 is inclined, and along the installation direction of the expansion device 71, the cross-sectional size of the limiting slide 321 perpendicular to the installation direction gradually decreases. This creates a dovetail-shaped enclosure structure, ensuring both stability and reliability during installation, and allowing the limiting slide 321 to accommodate the edge of the expansion device 71 with a thickness of 1.6±0.2mm. A gentle chamfer can also be provided within the limiting slide 321 to prevent scratching of components during card insertion.

[0054] like Figure 8 and Figure 9 As shown, the second positioning part 32 in this embodiment also adopts an L-shaped sheet structure. Two spaced protrusions are provided on the surface of the longitudinal section facing the receiving area, and the gap between the two protrusions is the limiting groove 321. A positioning post 322 is provided on the upper surface of the transverse section to achieve positioning and engagement with the main body 10. Simultaneously, the second connecting part 30 in this embodiment also includes a reinforcing part 33, which is connected to the second positioning part 32. The reinforcing part 33 can adopt a reinforcing rib or other structural form. The reinforcing part 33 is located on the outer surface of the second positioning part 32, that is, on the side of the L-shaped structure away from the receiving area. The reinforcing part 33 can be connected to both the longitudinal and transverse sections of the L-shaped structure, thereby enhancing the structural strength of the second positioning part 32 and ensuring the overall structural strength of the bracket.

[0055] like Figure 1 and Figure 2As shown, in this embodiment, the main body 10 includes a first plate segment 11 and a second plate segment 12 that are bent and connected in sequence. The first plate segment 11 and the second plate segment 12 form an accommodating area. In this embodiment, the first plate segment 11 and the second plate segment 12 are bent into an L-shape, and their size can be adapted to the size of the expansion card 70. The crease line between the first plate segment 11 and the second plate segment 12 extends along the direction from the first end to the second end. In this way, both the first end and the second end are open, so that the first connecting part 20 and the second connecting part 30 can be installed. The opening located between the first end and the second end can be used as an installation opening to realize the installation and locking of the expansion card 70. During installation, the expansion device 71 of the expansion card 70 is located at the first plate segment 11, thus cooperating with the first connecting structure and the first limiting member 41. The adapter device 72 of the expansion card 70 is located at the second plate segment 12, thus cooperating with the second connecting structure and the second limiting member 43. Since the adapter device 72 is farther from the mounting opening than the expansion device 71, the adapter device 72 is installed first, followed by the expansion device 71. During disassembly, the expansion device 71 is removed first, followed by the adapter device 72. A convex structure can be provided on the second plate segment 12 as needed to enhance structural strength.

[0056] Optionally, the main body 10, the first connecting part 20, and the second connecting part 30 can adopt an integrated structure as needed; they can also adopt a split structure with subsequent assembly; or both methods can be used simultaneously, that is, two of the three components are split structures, and the third component is integrated with one of the aforementioned two components. When an integrated structure is adopted, the first connecting part 20 and the second connecting part 30 are integrally formed with the main body 10. This embodiment adopts a split form, and both the first connecting part 20 and the second connecting part 30 are detachably connected to the main body 10. More specifically, in this embodiment, both the first connecting part 20 and the second connecting part 30 are provided with a mounting structure 50 between them and the main body 10. The mounting structure 50 includes mounting holes and mounting posts. In this embodiment, the mounting connection between the components is achieved through the installation of the mounting structure 50.

[0057] In addition to the aforementioned mounting structure 50, this embodiment also provides a positioning structure 60 between the first connecting part 20 and the second connecting part 30 and the main body part 10. The positioning structure 60 includes a positioning hole and a positioning protrusion. The positioning structure 60 enables the two components to be initially positioned during installation, and then the mounting structure 50 is used to lock them in place.

[0058] In this embodiment, the aforementioned mounting structure 50 and positioning structure 60 are provided between the first connecting body 21 and the main body 10, and between the second connecting body 31 and the main body 10. Specifically, the mounting structure 50 and positioning structure 60 are provided between the first connecting body 21 and the main body 10, between the second connecting body 31 and the main body 10, and between the second positioning part 32 and the main body 10. Thus, the mounting structure 50 and positioning structure 60 enable the connection between the two components. The specific number and position of the mounting structure 50 and positioning structure 60 between the two components can be adjusted as needed to ensure a stable and reliable connection. The mounting holes and positioning holes can be designed to compensate for minor machining tolerances to ensure the straightness of the overall frame after installation.

[0059] In this embodiment, since the overall structure of the first connecting part 20 and the second connecting part 30 is relatively complex, both are made of aluminum alloy to ensure the feasibility and strength of the structure. The main body 10 in the middle is made of stamped sheet metal to reduce manufacturing costs. The second limiting member 43 is made of stainless steel with a thickness of 0.1-0.5mm to ensure the elasticity and functional strength of this part. Since the second positioning part 32 is in contact with the expansion device 71, it is made of non-conductive plastic that will not damage the circuit board.

[0060] This embodiment also provides an electronic device, including an expansion card 70 and the aforementioned electronic device expansion card bracket. The expansion card 70 includes an expansion device 71 and an adapter device 72. As mentioned above, the expansion device 71 and the adapter device 72 are detachably mounted on the electronic device expansion card bracket via a first limiting member 41 and a second limiting member 43, respectively, and are effectively positioned and supported via a first connecting part 20 and a second connecting part 30. This ensures that the expansion device 71 and the adapter device 72 can be stably installed and supported, avoiding poor contact due to deformation at one end, and are also easy to disassemble, thus improving the installation and disassembly efficiency of the expansion card 70.

[0061] In this embodiment, one end of the adapter 72 is provided with a plug-in part for plugging into the first mounting part 23, and the other end is provided with a snap-fit ​​part for limiting and snapping into the snap-fit ​​protrusion 432. A connector is provided on the middle side of the adapter 72, so that the expansion device 71 can be plugged into the connector to realize the electrical connection between the expansion device 71 and the adapter 72, and at the same time play a certain positioning role.

[0062] It should be noted that "multiple" in the above embodiments refers to at least two.

[0063] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0064] By providing a first connecting part 20 and a second connecting part 30 at both ends of the main body 10, the three are used to install and accommodate the expansion card 70. The first connecting part 20 and the second connecting part 30 have a first connecting structure and a second connecting structure, respectively. When the expansion card 70 is installed into the accommodating area, the two ends of the expansion card 70 are respectively connected to the first connecting structure and the second connecting structure. The two ends of the expansion card 70 form a preliminary limiting relationship with the first connecting structure and the second connecting structure. At this time, the limiting effect of the first connecting structure and the second connecting structure on the expansion card 70 is small, and the expansion card 70 is still in a state where it can shake or even fall off. Since the first and second connecting structures only serve as preliminary limiting mechanisms, this embodiment also includes a limiting component. The limiting component engages with the initially installed expansion card 70, locking it in place. That is, when the expansion card 70 is placed in the container area, forming a preliminary engagement between the expansion card 70 and the first and second connecting structures, the limiting component blocks the path of the expansion card 70 out of the container area. This prevents the expansion card 70 from being disassembled, locking it to the bracket and preventing it from being disassembled. With the above-described configuration, since both ends of the expansion card 70 are supported by the first and second connecting structures respectively, both ends of the expansion card 70 can be effectively supported, preventing one end from sinking due to vibration or other factors. This ensures the stability and reliability of the expansion card 70 after installation, thereby guaranteeing the reliability of the connection at the gold fingers, ensuring system stability and data transmission performance. In addition, compared with the traditional screw installation method, the limiting component in this embodiment can adopt a quick-release structure, which can realize the quick switching between locking and unlocking of the limiting component, thereby achieving the purpose of quick installation and removal of the expansion card 70, facilitating maintenance and other operations.

[0065] The above provides a detailed description of an electronic device expansion card holder and an electronic device provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
