Description

Technical Field

[0001] This application relates to a fixing device, specifically to an expansion card module fixing device and an electronic device. Background Technology

[0002] Currently, with the rapid development of all aspects of society, the requirements for the efficiency of data center fault handling are becoming increasingly stringent. PCIe (Peripheral Component Interconnect Express) cards on servers are generally fixed with screws; that is, the PCIe card is directly inserted into the PCIe interface, and then the PCIe card cover is screwed onto the chassis. Repairing or replacing PCIe cards requires tools, causing considerable inconvenience and wasting a significant amount of time for users and maintenance personnel. There is an urgent need for a PCIe card fixing device that allows for tool-free, rapid installation and removal of PCIe cards to improve machine assembly efficiency. Summary of the Invention

[0003] In view of the above situation, it is necessary to provide an expansion card module fixing device to solve the problem that the installation or removal of expansion cards requires tools, which causes a lot of inconvenience to users and maintenance personnel.

[0004] This application provides an expansion card module fixing device, which includes a card bracket, a module bracket, a first connector, and a second connector. The card bracket is used to fix the expansion card. The module bracket includes a first fixing plate and a second fixing plate. The first fixing plate is perpendicular to a first direction, and the second fixing plate is perpendicular to a second direction. The module bracket is used to fix the card bracket. The first connector includes a first snap-fit ​​structure disposed on the card bracket. The first fixing plate has a first card slot with a first opening facing the first direction. The first snap-fit ​​structure can be inserted into the first card slot through the first opening to restrict the relative movement of the snap-fit ​​structure and the first fixing plate along the second direction. The second connector includes a second snap-fit ​​structure disposed on the card bracket. The second fixing plate has an insertion hole. The second snap-fit ​​structure can engage with the insertion hole to restrict the relative movement of the card bracket relative to the second fixing plate along the first direction.

[0005] In this expansion card module fixing device, a card bracket is used to fix the expansion card. The card bracket and the first fixing plate are connected through a first snap-fit ​​structure and a first card slot. The card bracket and the second fixing plate are connected through a second snap-fit ​​structure and a socket, thus fixing the card bracket and the module bracket. The module bracket is mounted on the housing, thereby fixing the expansion card to the housing. The inclusion of the first and second connectors allows for quick, tool-free installation and removal of the expansion card.

[0006] In some embodiments of this application, the expansion card module fixing device further includes a card pressing fastener, which is pivotally connected about an axis parallel to the second direction of the card bracket and can cooperate with the card bracket to clamp the expansion card.

[0007] In this expansion card module fixing device, after the expansion card is inserted into the card holder, rotating the card clamping fastener clockwise along the second direction engages with the card holder to secure the expansion card. When the expansion card needs to be removed from the card holder for repair or replacement, rotating the card clamping fastener counterclockwise along the second direction moves it away from the expansion card, allowing for easy removal. This expansion card module fixing device features a card clamping fastener for quick, tool-free installation and removal of the expansion card and card holder.

[0008] In some embodiments of this application, the clamping fastener extends along the length direction of the card holder.

[0009] In this expansion card module fixing device, the card clamping fastener extends along the length of the card bracket and can be made very thin, occupying very little space in the width direction of the card bracket.

[0010] In some embodiments of this application, the second fixing plate includes a support frame and a plate body, the plate body being perpendicular to the second direction, and the support frame being perpendicular to and fixedly connected to the plate body.

[0011] The second fixed plate includes a support frame and a plate body. The support frame and the plate body are vertically fixed. The end of the support frame away from the plate body is connected to the card bracket through a connector. The fixed height and position of the card bracket relative to the plate body can be adjusted by adjusting the position and height of the support frame.

[0012] In some embodiments of this application, the first snap-fit ​​structure includes a first column portion connected to the card bracket and a first snap-fit ​​portion connected to the first column portion. The first column portion is used to insert into the first card slot, and the first snap-fit ​​portion is used to lock into the first fixing plate along the second direction.

[0013] In this expansion card module fixing device, the first snap-fit ​​structure includes a first column part and a first snap-fit ​​part. By sliding the first column part in the first card slot and by contacting or disengaging the first snap-fit ​​part from the first card slot, the connection or disassembly of the card bracket and the first fixing plate can be quickly achieved without tools.

[0014] In some embodiments of this application, the second snap-fit ​​structure includes a handle, a locking rod, a rotating shaft, and a base. One end of the locking rod passes through the base and is connected to the rotating shaft. The handle is rotatably connected to the locking rod via the rotating shaft. One end of the handle has an arc-shaped surface. When the handle rotates around the rotating shaft, the base acts on the handle through the arc-shaped surface to drive the rotating shaft and the locking rod to move relative to the base parallel to the second direction.

[0015] In this expansion card module fixing device, the curved surface of the handle slides on the base near the handle, causing the rotating shaft to move closer to or away from the base along a second direction. One end of the locking lever passes through the base and connects to the rotating shaft, which drives the locking lever to move relative to the base in the second direction or the opposite direction. When the handle is pressed down, the rotating shaft drives the locking lever to move relative to the base in the second direction, allowing the other end of the locking lever to pass sequentially through the through hole and the insertion hole of the card bracket along the second direction, thus connecting the card bracket and the support frame, i.e., connecting the card bracket and the second fixing plate. When the handle is lifted, the rotating shaft drives the locking lever to move relative to the base in the opposite direction of the second direction, causing the other end of the locking lever to move away from the insertion hole, thus disconnecting the card bracket and the support frame, i.e., disconnecting the card bracket and the second fixing plate. The quick-release lock allows for quick, tool-free connection or disassembly of the card bracket and the second fixing plate.

[0016] In some embodiments of this application, the expansion card module fixing device further includes a third connector, the third connector including a third snap-fit ​​structure, the module bracket further including a third fixing plate, the third fixing plate being perpendicular to a third direction; the third fixing plate is provided with a third slot, the third slot having a second opening facing the first direction and a hanging groove communicating with the second opening, the third snap-fit ​​structure being fixedly connected to the card bracket, and the third snap-fit ​​structure being able to be inserted into the third slot from the opening to restrict movement.

[0017] In this expansion card module fixing device, the opening has a guiding function, allowing the third snap-fit ​​structure to quickly reach the hanging slot through the opening. The hanging slot and the third snap-fit ​​structure are engaged, which can quickly connect the card bracket and the third fixing plate without tools.

[0018] In some embodiments of this application, the expansion card module fixing device further includes a fourth connector, which includes a fourth snap-fit ​​structure. The card holder has a fourth slot, and the fourth snap-fit ​​structure is fixed to the second fixing plate. The fourth snap-fit ​​structure can be inserted into the fourth slot to restrict the relative movement of the card holder and the second fixing plate along the second direction. In this expansion card module fixing device, the fourth connector can further increase the fixing stability of the card holder and the second fixing plate.

[0019] In some embodiments of this application, the fourth slot is a snap-fit ​​hole, which includes a wide opening and a narrow opening communicating with the wide opening. The wide opening and the narrow opening are arranged along the length direction of the card bracket. The fourth snap-fit ​​structure includes a second column portion connected to the support frame and a second snap-fit ​​portion connected to the second column portion. The second column portion is used to pass through the narrow opening, and the second snap-fit ​​portion is used to pass through the wide opening and contact and engage with the narrow opening.

[0020] In this expansion card module fixing device, the snap-fit ​​hole includes a wide opening and a narrow opening. The fourth snap-fit ​​structure includes a second column part and a second snap-fit ​​part. After the second snap-fit ​​part extends into the snap-fit ​​hole through the wide opening, the wide opening communicates with the narrow opening. By moving the card bracket along the second direction, the second column part is inserted into the narrow opening, and the second snap-fit ​​part is located at the narrow opening. The narrow opening and the second snap-fit ​​part contact and cooperate, restricting the relative movement of the fourth snap-fit ​​structure and the fourth card slot along the second direction, so as to realize the tool-free quick connection of the card bracket and the second fixing plate.

[0021] In some embodiments of this application, the module bracket is disposed on the housing, and a portion of the housing serves as the first fixing plate, the second fixing plate, and the third fixing plate of the module bracket.

[0022] There is no need to design separate first, second, and third fixing plates, saving materials and reducing costs.

[0023] Another aspect of the embodiments of this application provides an electronic device including the expansion card module fixing device in any of the above embodiments.

[0024] This electronic device can quickly install and remove expansion cards without tools using an expansion card module fixing device. Attached Figure Description

[0071] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0072] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0073] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have a component that is centrally located. When a component is considered to be "set" on another component, it can be directly set on the other component or may also have a component that is centrally located.

[0074] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0075] This application provides an expansion card module fixing device, which includes a card bracket, a module bracket, a first connector, and a second connector. The card bracket is used to fix the expansion card. The module bracket includes a first fixing plate and a second fixing plate. The first fixing plate is perpendicular to a first direction, and the second fixing plate is perpendicular to a second direction. The module bracket is used to fix the card bracket. The first connector includes a first snap-fit ​​structure disposed on the card bracket. The first fixing plate has a first card slot with a first opening facing the first direction. The first snap-fit ​​structure can be inserted into the first card slot through the first opening to restrict the relative movement of the card bracket and the first fixing plate along the second direction. The second connector includes a second snap-fit ​​structure disposed on the card bracket. The second fixing plate has an insertion hole. The second snap-fit ​​structure can be inserted into the insertion hole to restrict the relative movement of the card bracket relative to the second fixing plate along the first direction.

[0076] In this expansion card module fixing device, a card bracket is used to fix the expansion card. The card bracket and the first fixing plate are connected through a first snap-fit ​​structure and a first card slot. The card bracket and the second fixing plate are connected through a second snap-fit ​​structure and a socket, thus fixing the card bracket and the module bracket. The module bracket is mounted on the housing, thereby fixing the expansion card to the housing. The inclusion of the first and second connectors allows for quick, tool-free installation and removal of the expansion card.

[0077] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0078] Please see Figure 1 and Figure 2 One embodiment of this application provides an expansion card module fixing device 100, which can install and remove expansion cards 200 without tools, thereby improving the efficiency of machine assembly and maintenance.

[0079] The expansion card module fixing device 100 includes a card bracket 50, a module bracket 60, a first connector 10, and a second connector 20. The card bracket 50 is used to fix the expansion card 200. The module bracket 60 is disposed on the housing 300 and is used to fix the card bracket 50.

[0080] Expansion card 200 includes PCIe card, PCI card or other functional modules with similar functions, mainly used to electrically connect to the circuit board to expand the circuit board's performance, such as network card, graphics card, adapter card, PCIe acquisition card, etc.

[0081] For ease of description, the length direction of the card holder 50 is defined as the first direction X, the width direction as the third direction Y, and the thickness direction as the second direction Z in the following description.

[0082] The expansion card module fixing device 100 also includes a card clamping fixing member 51, which is rotatably mounted on the card holder 50. Specifically, the card clamping fixing member 51 is pivotally connected about an axis parallel to the thickness direction of the card holder 50. When the expansion card 200 is inserted into the card holder 50, viewed along the second direction Z, rotating the card clamping fixing member 51 clockwise causes the card clamping fixing member 51 and the card holder 50 to clamp the expansion card 200, thus fixing the expansion card 200. When it is necessary to remove the expansion card 200 from the card holder 50 for maintenance or replacement, viewed along the second direction Z, rotating the card clamping fixing member 51 counterclockwise causes the card clamping fixing member 51 to move away from the expansion card 200, thereby removing the expansion card 200. The card clamping fixing member 51 facilitates quick, tool-free installation and removal of the expansion card 200 and the card holder 50.

[0083] Please see Figure 3 Specifically, the card holder 50 is provided with a rotating shaft 52, and the card clamping fastener 51 is provided with a card hole that cooperates with the rotating shaft 52. The card clamping fastener 51 is sleeved on the rotating shaft 52 through the card hole, and the card clamping fastener 51 can rotate around the rotating shaft 52.

[0084] Specifically, the shape of the card hole can be determined according to actual needs, and a circular hole is preferred.

[0085] In one embodiment, the card clamping fastener 51 extends along the first direction X. When viewed along the third direction Y, the projection surface of the card clamping fastener 51 on the card holder 50 does not exceed the periphery of the card holder 50. Preferably, the dimension of the card clamping fastener 51 in the second direction Z is approximately equal to the dimension of the card holder 50 in the second direction Z. The card clamping fastener 51 extends along the length direction of the card holder 50 and can be made very thin, so that the card clamping fastener 51 occupies very little space in the width direction of the card holder 50.

[0086] The module bracket 60 includes a first fixing plate 61, a second fixing plate 62, and a third fixing plate 63. The first fixing plate 61 is perpendicular to the first direction X, the second fixing plate 62 is perpendicular to the second direction Z, and the third fixing plate 63 is perpendicular to the third direction Y, so that the module bracket 60 has fixing surfaces in three directions: the first direction X, the third direction Y, and the second direction Z. The module bracket 60 can limit the displacement of the card bracket 50 from three directions, thereby improving the fixing stability of the module bracket 60 on the card bracket 50.

[0087] Please also refer to Figure 2The first fixing plate 61 has a window 615. The first fixing plate 61 includes a top plate 611, a bottom plate 612, a first side plate 613, and a second side plate 614. The top plate 611, the bottom plate 612, the first side plate 613, and the second side plate 614 form the window 615. When the card bracket 50 is placed into the module bracket 60, the card pressing fastener 51 passes through and partially extends out of the window 615. The first side plate 613 contacts or approaches the card pressing fastener 51, limiting the displacement of the card pressing fastener 51. When viewed along the second direction Z, it makes it difficult for the card pressing fastener 51 to rotate counterclockwise away from the thickness direction of the expansion card 200, which can further increase the fixing stability of the expansion card 200.

[0088] The first connector 10 includes a first snap-fit ​​structure 11, which is disposed on the card bracket 50. The top plate 611 is provided with a first card slot 12. The first snap-fit ​​structure 11 and the first card slot 12 engage to achieve the connection between the card bracket 50 and the first fixing plate 61 in the second direction Z.

[0089] Preferably, there are two first connectors 10, which are spaced apart along the length of the card holder 50. This can increase the balance of the card holder 50 when it is fixed, thereby increasing the stability of the card holder 50.

[0090] In other embodiments, the first connector 10 may also be configured in other quantities, such as three or four, which is not limited here.

[0091] In one embodiment, the first snap-fit ​​structure 11 includes a first column portion 111 connected to the card bracket 50 and a first snap-fit ​​portion 112 connected to the first column portion 111. The first column portion 111 is used to insert into the first card slot 12, and the first snap-fit ​​portion 112 is in contact with the top plate 611. That is, the side of the first snap-fit ​​portion 112 facing the second fixing plate 62 is in contact with the side of the top plate 611 away from the second fixing plate 62, thereby preventing the first snap-fit ​​portion 112 and the top plate 611 from moving along the second direction Z.

[0092] Specifically, the outer diameter of the first column portion 111 is smaller than the outer diameter of the first latching portion 112, and the outer diameter of the first column portion 111 is smaller than the cross-sectional width of the first latching groove 12, so that the first column portion 111 can be inserted into the first latching groove 12. The outer diameter of the first latching portion 112 is larger than the cross-sectional width of the first latching groove 12. When the first column portion 111 extends into the first latching groove 12 in the opposite direction of the first direction X, the first latching groove 12 engages with the first latching portion 112, thereby restricting the relative movement of the card bracket 50 and the first fixing plate 61 in the second direction Z.

[0093] In one embodiment, the first slot 12 is a U-shaped slot with the opening of the U-shaped slot away from the top plate 611 along the first direction X. The U-shaped slot is flared to facilitate the first snap-fit ​​structure 11 to slide quickly into the first slot 12 in the opposite direction of the first direction X.

[0094] Please also refer to Figure 4 In one embodiment, the second fixing plate 62 includes a support frame 621 and a plate body 622. The plate body 622 is perpendicular to the second direction Z, and the support frame 621 is fixedly connected to the plate body 622. The second connecting member 20 includes a second snap-fit ​​structure 21. The second snap-fit ​​structure 21 is disposed on the card bracket 50, and the support frame 621 is provided with an insertion hole 22. The second snap-fit ​​structure 21 engages with the insertion hole 22 to realize the connection between the card bracket 50 and the support frame 621 along the first direction X, that is, to realize the connection between the card bracket 50 and the second fixing plate 62 along the first direction X.

[0095] Specifically, the second latching structure 21 is a quick-release lock, and the insertion hole 22 is a through hole. The quick-release lock includes a handle 211, a locking bar 212, a rotating shaft 213, and a base 214. The handle 211 can rotate around the rotating shaft 213 and is mounted on the base 214. The end of the handle 211 near the base 214 has an arc-shaped surface. When the handle 211 rotates around the rotating shaft 213, the arc-shaped surface slides on the surface of the base 214 near the handle 211, causing the rotating shaft 213 to move closer to or further away from the base 214 along the second direction Z. One end of the locking bar 212 passes through the base 214 and connects to the rotating shaft 213. The rotating shaft 213 drives the locking bar 212 to move relative to the base 214 in the second direction Z or the opposite direction of the second direction Z. When handle 211 is pressed, shaft 213 drives locking rod 212 to move relative to base 214 in the second direction Z, allowing the other end of locking rod 212 to pass sequentially through the through hole and insertion hole 22 of card bracket 50 in the second direction Z, thus connecting card bracket 50 and support frame 621, i.e., connecting card bracket 50 and second fixing plate 62. When handle 211 is lifted, shaft 213 drives locking rod 212 to move relative to base 214 in the opposite direction of the second direction Z, causing the other end of locking rod 212 to move away from insertion hole 22, thus disconnecting card bracket 50 and support frame 621, i.e., disconnecting card bracket 50 and second fixing plate 62. The quick-release lock allows for quick and tool-free connection or disassembly of card bracket 50 and second fixing plate 62.

[0096] In one embodiment, the expansion card module fixing device 100 further includes a third connector 30, which includes a third snap-fit ​​structure 31. A third slot 32 is provided on the third fixing plate 63, and the third snap-fit ​​structure 31 is fixedly connected to the card bracket 50. The connection between the third slot 32 and the third snap-fit ​​structure 31 realizes the connection between the card bracket 50 and the third fixing plate 63 along the third direction Y.

[0097] In one embodiment, the third slot 32 has a second opening 321 at the edge facing the first direction X and a hanging groove 322 communicating with the second opening 321. The third snap-fit ​​structure 31 slides into the second opening 321 in the opposite direction of the first direction X and is positioned in the hanging groove 322, which can quickly realize the connection between the card bracket 50 and the third fixing plate 63 along the third direction Y.

[0098] In one embodiment, the third snap-fit ​​structure 31 includes a third column portion 311 connected to the card bracket 50 and a third snap-fit ​​portion 312 connected to the third column portion 311. The third column portion 311 is used to pass through the third card slot 32, and the third snap-fit ​​portion 312 is used to snap-fit ​​with the third card slot 32.

[0099] Specifically, the outer diameter of the third column portion 311 is smaller than the outer diameter of the third snap-fit ​​portion 312, and the outer diameter of the third column portion 311 is smaller than the cross-sectional width of the hanging groove 322, allowing the third column portion 311 to pass through the hanging groove 322. The outer diameter of the third snap-fit ​​portion 312 is larger than the cross-sectional width of the hanging groove 322. When the third column portion 311 slides into the hanging groove 322 in the opposite direction of the first direction X, the hanging groove 322 and the third snap-fit ​​portion 312 engage to achieve the connection between the card bracket 50 and the third fixing plate 63 in the third direction Y.

[0100] In one embodiment, the expansion card module fixing device 100 further includes a fourth connector 40, which includes a fourth snap-fit ​​structure 41. The card bracket 50 is provided with a fourth card slot 42. The fourth snap-fit ​​structure 41 is fixedly connected to the support frame 621. The snap-fit ​​cooperation between the fourth snap-fit ​​structure 41 and the fourth card slot 42 further increases the stability of the connection between the card bracket 50 and the second fixing plate 62 along the second direction Z.

[0101] In one embodiment, the fourth slot 42 is a snap-fit ​​hole, which includes a wide opening 421 and a narrow opening 422 communicating with the wide opening 421. The wide opening 421 and the narrow opening 422 are arranged along the second direction Z. The fourth snap-fit ​​structure 41 includes a second column portion 411 connected to the support frame 621 and a second snap-fit ​​portion 412 connected to the second column portion 411. The second column portion 411 is used to pass through the narrow opening 422, and the second snap-fit ​​portion 412 is used to pass through the wide opening 421 and snap-fit ​​with the narrow opening 422.

[0102] Specifically, the outer diameter of the second column portion 411 is smaller than the outer diameter of the second snap-fit ​​portion 412, and the outer diameter of the second column portion 411 is smaller than the cross-sectional width of the constricted opening 422, allowing the second column portion 411 to pass through the constricted opening 422. The outer diameter of the second snap-fit ​​portion 412 is smaller than the cross-sectional width of the wide opening 421, and the outer diameter of the second snap-fit ​​portion 412 is larger than the cross-sectional width of the constricted opening 422. Therefore, the second snap-fit ​​portion 412 can only extend into the snap-fit ​​hole through the wide opening 421, and not through the constricted opening 422, when it moves in the opposite direction of the second direction Z. After the second snap-fit ​​portion 412 extends into the snap-fit ​​hole through the wide opening 421, the wide opening 421 communicates with the constricted opening 422. By moving the card bracket 50 along the first direction X, the second column portion 411 falls into the constricted opening 422, and the constricted opening 422 engages with the second snap-fit ​​portion 412, achieving tool-free quick connection of the card bracket 50 and the second fixing plate 62 along the second direction Z.

[0103] When it is necessary to disconnect the card bracket 50 and the second fixing plate 62, the card bracket 50 is moved along the first direction X so that the second column part 411 falls from the constriction 422 into the wide opening 421. When the second snap-fit ​​part 412 is located at the wide opening 421, the second snap-fit ​​part 412 can pass through the wide opening 421 along the second direction Z to realize that the fourth snap-fit ​​structure 41 is disengaged from the snap-fit ​​hole, thereby realizing the separation of the card bracket 50 and the second fixing plate 62.

[0104] In one embodiment, the module bracket 60 is disposed on the housing 300, and a portion of the housing 300 serves as the first fixing plate 61, the second fixing plate 62, and the third fixing plate 63 of the module bracket 60. This eliminates the need for separate design of the first fixing plate 61, the second fixing plate 62, and the third fixing plate 63, saving materials and reducing costs.

[0105] Preferably, the first snap-fit ​​structure 11, the third snap-fit ​​structure 31 and the fourth snap-fit ​​structure 41 have the same structure, which facilitates mold making and installation and reduces costs.

[0106] Preferably, the first snap-fit ​​structure 11, the third snap-fit ​​structure 31, and the fourth snap-fit ​​structure 41 are I-shaped pins. I-shaped pins can be purchased directly from the market without additional processing, saving mold-making costs.

[0107] The tool-free quick installation process for the expansion card 200 includes the following steps:

[0108] First, place the expansion card 200 on the card holder 50. Observe along the second direction Z and rotate the card clamping fastener 51 clockwise so that the card clamping fastener 51 and the card holder 50 cooperate to clamp the expansion card 200, thereby fixing the expansion card 200.

[0109] Then, the second snap-fit ​​portion 412 of the fourth snap-fit ​​structure 41 passes through the wide opening 421 of the snap-fit ​​hole in the opposite direction of the second direction Z, and then moves the card bracket 50 in the opposite direction of the first direction X so that the second column portion 411 falls into the narrow opening 422. The narrow opening 422 engages with the second snap-fit ​​portion 412, realizing the connection between the card bracket 50 and the second fixing plate 62 in the second direction Z. At the same time, the third snap-fit ​​structure 31 on the card bracket 50 slides into the second opening 321 at the edge of the third slot 32 in the opposite direction of the first direction X, and is positioned in the hanging slot 322, quickly realizing the connection between the card bracket 50 and the third fixing plate 63 in the third direction Y. At the same time, the first column portion 111 of the first snap-fit ​​structure 11 on the card bracket 50 moves in the opposite direction of the first direction X and extends into the first slot 12. The first snap-fit ​​portion 112 engages with the first slot 12, realizing the connection between the card bracket 50 and the first fixing plate 61 in the third direction Y.

[0110] Finally, press down the handle 211 of the quick-release lock on the card bracket 50. The locking rod 212 moves along the second direction Z, passing through the through hole and the insertion hole 22 of the card bracket 50 in sequence, thereby connecting the card bracket 50 and the support frame 621 along the first direction X, that is, connecting the card bracket 50 and the second fixing plate 62. Tool-free quick installation of the expansion card 200 is completed.

[0111] The tool-free quick removal process for the expansion card 200 includes the following steps:

[0112] First, lift the handle 211 of the quick-release lock on the card holder 50. The locking rod 212 moves in the opposite direction of the third direction Y and leaves the socket 22. That is, the card holder 50 and the socket 22 are disconnected in the first direction X.

[0113] Then, the card holder 50 is moved along the first direction X, causing the third snap-fit ​​structure 31 on the card holder 50 to slide out of the mounting groove 322 and leave the third slot 32 through the second opening 321, thus releasing the connection between the card holder 50 and the third fixing plate 63 along the third direction Y. Simultaneously, the first column portion 111 of the first snap-fit ​​structure 11 on the card holder 50 slides out of the first slot 12 along the first direction X, releasing the snap-fit ​​relationship between the first snap-fit ​​portion 112 and the first slot 12 along the second direction Z. At the same time, the fourth snap-fit ​​structure 41 slides from the constricted opening 422 into the wide opening 421 along the first direction X, and the second snap-fit ​​portion 412 leaves the fourth slot 42 through the wide opening 421 in the opposite direction of the second direction Z, releasing the connection between the card holder 50 and the second fixing plate 62 along the first direction X. At this point, the connection between the card holder 50 and the module bracket 60 is released.

[0114] After removing the card holder 50, observe along the second direction Z, rotate the card clamping fastener 51 counterclockwise so that the card clamping fastener 51 moves away from the expansion card 200, and then remove the expansion card 200.

[0115] Another aspect of this application provides an electronic device including the expansion card module fixing device 100 as described above. This electronic device allows for quick and tool-free installation and removal of the expansion card 200. The electronic device may be, but is not limited to, a personal computer or a server.
