Description

Technical Field

[0001] The invention relates to a server and an adapter card bearing seat. Background Art

[0002] In current servers, the adapter card for expansion cards to be plugged into is fastened to the carrier by screws, and the carrier is also fixed to the housing by screws. However, in the process of disassembling and assembling the adapter card, manual installation and removal of the screws are required, which takes a certain amount of time and requires additional jigs or tools. Furthermore, as the electronic components in the server are configured more and more compactly, the space available for users to use tools to install and remove screws is increasingly insufficient, making it difficult to smoothly install and disassemble the adapter card, which increases the operation time. In addition, the use of screws to fix the adapter card will also incur material costs for the screws. Therefore, researchers in this field are currently working hard to solve the problem of the difficulty in reducing the operation time and material costs derived from the use of screws to fix the adapter card. Summary of the invention

[0003] The present invention provides a server and an adapter card bearing seat, which can save the operation time and material cost required for disassembling and assembling the adapter card.

[0004] A server disclosed in one embodiment of the present invention comprises a housing, a motherboard, an adapter card holder, an adapter card and an expansion card. The motherboard is located in the housing. The adapter card holder comprises a main body, a first retaining member and a second retaining member. The main body is fixed in the housing, the first retaining member and the second retaining member are respectively connected to different positions of the main body, and the first retaining member and the second retaining member are asymmetrically arranged relative to the main body. The adapter card is mounted on the main body and electrically connected to the motherboard. The first retaining member and the second retaining member are detachably fixed to the adapter card. The expansion card is plugged into the adapter card.

[0005] Another embodiment of the present invention discloses an adapter card holder for carrying an adapter card, comprising a main body, a first retaining member and a second retaining member. The main body is used for assembling the adapter card. The first retaining member and the second retaining member are respectively connected to different locations of the main body, and the first retaining member and the second retaining member are asymmetrically arranged relative to the main body. The first retaining member and the second retaining member are respectively used to detachably clamp to the adapter card.

[0006] According to the server and the adapter card holder disclosed in the above embodiments, the adapter card is installed on the main body of the adapter card holder and is fixed by the first retaining member and the second retaining member that are asymmetrically arranged relative to the main body of the adapter card holder, so the adapter card can be removed and assembled in a tool-free manner. Therefore, the operation time and tools required for installing and removing screws can be saved, the probability of damaging the adapter card during the installation and removal of screws and the material cost of the screws can be reduced, and even if the space where the adapter card is located is very narrow, the adapter card can still be removed and assembled smoothly.

[0084] See also Figure 1 and Figure 2 . Figure 1 It is a partial three-dimensional schematic diagram of a server disclosed according to the first embodiment of the present invention. Figure 2 for Figure 1 Schematic diagram of the exploded view of the adapter card and the adapter card carrier.

[0085] In this embodiment, the server 1 includes a housing 10, a motherboard 20, a riser card holder 30, a riser card 40 and an expansion card 50. The motherboard 20 is located in the housing 10 and has an electrical connector 21.

[0086] Next, see Figures 3 to 6 . Figure 3 for Figure 2 A partially enlarged exploded diagram of the adapter card holder. Figure 4 for Figure 2 A partially enlarged exploded diagram of an adapter card and an adapter card carrier. Figure 5 for Figure 1 A side view schematic diagram of an adapter card and an adapter card bearing seat. Figure 6 for Figure 1 A partial cross-sectional schematic diagram of an adapter card and an adapter card bearing seat.

[0087] The adapter card holder 30 includes a main body 31, a first retaining member 32 and a second retaining member 33. The main body 31 is fixed in the housing 10 by screws (not shown), for example. The main body 31 includes a first side portion 31A and a second side portion 31B connected to each other. The first side portion 31A of the main body 31 has a receiving groove 311 and two opposite inner wall surfaces 3111 forming the receiving groove 311. In addition, the first side portion 31A of the main body 31 also has a first limiting portion 312, a second limiting portion 313, two first abutting ribs 314, a supporting structure 315 and two pivot holes 316. The first limiting portion 312 is located on one side of the receiving groove 311, and the second limiting portion 313 maintains a distance from the first limiting portion 312. The two first abutting ribs 314 protrude from the two inner wall surfaces 3111 respectively, and are located between the first limiting portion 312 and the second limiting portion 313. The supporting structure 315 is located in the receiving groove 311 and is located on the side of the second limiting portion 313 away from the two first abutting ribs 314. The supporting structure 315 has a first notch 3151. The two pivot holes 316 are respectively located on the two inner wall surfaces 3111 of the main body 31. The second side portion 31B of the main body 31 has a positioning hole 317. The purposes of the aforementioned receiving groove 311, the first limiting portion 312, the second limiting portion 313, the first abutting ribs 314, the supporting structure 315, the pivot hole 316 and the positioning hole 317 will be described in detail later.

[0088] The first retaining member 32 and the second retaining member 33 are respectively connected to different locations of the main body 31, and the first retaining member 32 and the second retaining member 33 are asymmetrically arranged relative to the main body 31. The asymmetrical arrangement of the first retaining member 32 and the second retaining member 33 relative to the main body 31, for example, means that the structures of the first retaining member 32 and the second retaining member 33 are asymmetrical relative to the center of the main body 31, and the positions of the first retaining member 32 and the second retaining member 33 are asymmetrical relative to the center of the main body 31. The detailed structures of the first retaining member 32 and the second retaining member 33 will be described in detail below.

[0089] The first holding member 32 includes a pivoting portion 321, an extending portion 322 and a holding portion 323. In addition, the first holding member 32 may further include a pushing portion 324. The pivoting portion 321 and the holding portion 323 are respectively connected to two opposite ends of the extending portion 322. The pushing portion 324 and the holding portion 323 protrude from the extending portion 322 in the same direction, and the pushing portion 324 is separated from the holding portion 323 and is closer to the pivoting portion 321 than the holding portion 323. The pivoting portion 321 and a portion of the extending portion 322 are located in the receiving groove 311 and between the two inner wall surfaces 3111. The pivoting portion 321 has two opposite pivoting posts 3211. The two pivoting posts 3211 are combined with two pivoting holes 316 of the first side portion 31A of the main body 31, so that the pivoting portion 321 can pivot relative to the main body 31. The first limiting portion 312 and the second limiting portion 313 of the main body 31 of the riser card holder 30 correspond to the extension portion 322 and the abutment portion 324 of the first retaining member 32, respectively, to limit the pivoting angle range of the first retaining member 32. In other words, the first limiting portion 312 and the second limiting portion 313 of the main body 31 of the riser card holder 30 limit the first retaining member 32 to only one fixed position (e.g. Figure 6 shown in the position) and a release position (e.g. Figure 7 positions shown).

[0090] In this embodiment, the extending portion 322 of the first retaining member 32 has two opposite second abutting ribs 3221 . The two second abutting ribs 3221 are respectively used to abut against the two first abutting ribs 314 of the main body 31 of the riser card holder 30 .

[0091] The second holding member 33 includes a first hook 331 and a second hook 332. The first hook 331 includes a first connecting arm 3311 and a first block 3312. One end of the first connecting arm 3311 is connected to the main body 31, and the first block 3312 protrudes from the end of the first connecting arm 3311 away from the main body 31. The second hook 332 includes a second connecting arm 3321 and a second block 3322. One end of the second connecting arm 3321 is connected to the main body 31 and is located between the first hook 331 and the first holding member 32. The second block 3322 protrudes from the end of the second connecting arm 3321 away from the main body 31. Figure 4 and Figure 5 As shown, the length L1 of the second locking block 3322 of the second hook 332 protruding from the second connecting arm 3321 is, for example, smaller than the length L2 of the first locking block 3312 of the first hook 331 protruding from the first connecting arm 3311 .

[0092] In this embodiment, the first block 3312 has a first push inclined surface 33121 and a first abutting inclined surface 33122, and the first push inclined surface 33121 and the first abutting inclined surface 33122 face different directions. The second block 3322 has a second push inclined surface 33221 and a second abutting inclined surface 33222, and the second push inclined surface 33221 and the second abutting inclined surface 33222 face different directions.

[0093] The adapter card 40 can support any level of expansion card, such as PCIe 4.0 or PCIe 5.0 expansion card. The adapter card 40 includes a circuit board 41, a main electrical connector 42, a cable 43, a sub-electrical connector 44 (such as Figure 1 The circuit board 41 has a first surface 411, a second surface 412 and a second notch 413. The first surface 411 is opposite to the second surface 412, and the second notch 413 is formed by recessing from the edge of the circuit board 41. The main electrical connector 42 is disposed on the first surface 411 of the circuit board 41. One end of the cable 43 is disposed on the second surface 412 of the circuit board 41, and the other end is connected to the sub-electrical connector 44. Figure 1 As shown, the sub-electrical connector 44 is assembled with the electrical connector 21 of the motherboard 20, so that the circuit board 41 is electrically connected to the motherboard 20 through the cable 43. The cover 45 is disposed on the circuit board 41 and shields part of the cable 43 to provide a function of protecting the connection between the cable 43 and the circuit board 41. The cover 45 of the adapter card 40 has a positioning column 451 and an elongated convex rib 452, and the elongated convex rib 452 has a push-against inclined surface 4521 and a push-against arc surface 4522 separated from each other. The purpose of the push-against inclined surface 4521 and the push-against arc surface 4522 of the elongated convex rib 452 of the cover 45 will be described in detail later.

[0094] like Figures 4 to 6As shown, when the adapter card 40 is assembled on the adapter card carrier 30, the positioning column 451 of the adapter card 40 is inserted into the positioning hole 317 of the main body 31, the circuit board 41 of the adapter card 40 is partially located in the accommodating groove 311 of the main body 31, the supporting structure 315 of the main body 31 is located in the second notch 413 of the circuit board 41 of the adapter card 40 and supports the circuit board 41, and the first notch 3151 of the supporting structure 315 corresponds to the inner edge 4131 of the second notch 413 of the circuit board 41. In addition, the first retaining member 32 is located at the clamping position, and the two second abutting ribs 3221 of the extending portion 322 of the first retaining member 32 respectively abut against the two first abutting ribs 314 of the main body 31, and the pushing portion 324 of the first retaining member 32 is located in the second notch 413 of the circuit board 41. One side of the pushing portion 324 of the first retaining member 32 abuts against the second limiting portion 313, and the other side and the retaining portion 323 respectively abut against the two opposite sides of the adapter card 40, so that the first retaining member 32 is clamped on the circuit board 41. Furthermore, the first block 3312 of the first hook 331 of the second retaining member 33 and the second block 3322 of the second hook 332 are fixed to the elongated convex rib 452 of the cover body 45 of the adapter card 40, so that the first abutting inclined surface 33122 of the first block 3312 and the second abutting inclined surface 33222 of the second block 3322 face the pushing arc surface 4522 of the elongated convex rib 452.

[0095] In this embodiment, the positioning post 451 of the adapter card 40 is inserted into the positioning hole 317 of the main body 31, which can limit the horizontal displacement of the adapter card 40 on the long axis L of the main body 31. In addition, the holding portion 323 of the first holding member 32 of the adapter card holder 30 and the first hook 331 and the second hook 332 of the second holding member 33 can limit the vertical displacement of the adapter card 40 in the height direction H of the main body 31.

[0096] It should be noted that the positioning column 451 of the adapter card 40 and the positioning hole 317 of the main body 31 are optional structures. In other embodiments, the adapter card may not have a positioning column, and the main body may not have a positioning hole, and the limitation of the horizontal displacement of the adapter card may be achieved by other suitable structures.

[0097] Furthermore, by disposing the two second abutting ribs 3221 of the extension portion 322 of the first retaining member 32 to abut against the two first abutting ribs 314 of the main body 31 respectively, the first retaining member 32 can be prevented from unexpectedly pivoting toward the release position to ensure that the first retaining member 32 remains in the clamping position and is clamped to the circuit board 41 of the adapter card 40.

[0098] It should be noted that the two first abutting ribs 314 of the main body 31 and the two second abutting ribs 3221 of the extension 322 of the first retaining member 32 are optional structures. In other embodiments, the main body may not have the first abutting ribs, the extension of the first retaining member may not have the second abutting ribs, and limiting the first retaining member in the locking position may be achieved by other suitable structures.

[0099] In this embodiment, the first notch 3151 of the support structure 315 can prevent the support structure 315 from interfering with the inner edge 4131 of the second notch 413 of the circuit board 41 , thereby ensuring that the circuit board 41 is evenly supported by the support structure 315 .

[0100] It should be noted that the first notch 3151 of the support structure 315 is an optional structure. If the manufacturing precision of the support structure and the circuit board is good, so that there is no concern that the support structure and the inner edge of the second notch of the circuit board will interfere with each other, the first notch of the support structure can be omitted. On the other hand, the second notch of the circuit board is an optional structure. In other embodiments, the circuit board may not have the second notch, and the support structure of the main body can be omitted accordingly.

[0101] like Figure 1 As shown, the expansion card 50 is, for example, an expansion card of any level, such as a PCIe 4.0 or PCIe 5.0 expansion card 50, which is plugged into the main electrical connector 42 of the circuit board 41 of the adapter card 40, so that the expansion card 50 is electrically connected to the motherboard 20 through the circuit board 41 of the adapter card 40 and the cable 43.

[0102] Next, see Figure 4 , Figure 6 and Figure 7 , Figure 7 for Figure 6 A partial cross-sectional schematic diagram of the first retaining member of the adapter card carrier being operated.

[0103] When the user wants to remove the riser card 40 from the riser card holder 30, the user can apply force to the holding portion 323 of the first holding member 32 along the direction D1, so that the two second abutting ribs 3221 of the extension portion 322 of the first holding member 32 pass over the two first abutting ribs 314 of the main body 31, and the first holding member 32 is pivoted from the locking position to the releasing position. During the process of the first holding member 32 pivoting toward the releasing position, the holding portion 323 will gradually separate from the circuit board 41, and the abutting portion 324 of the first holding member 32 will lift up one side of the circuit board 41 of the riser card 40. During the process of lifting one side of the circuit board 41, since the protruding length of the second block 3322 of the second hook 332 is shorter than the protruding length of the first block 3312 of the first hook 331, the pushing arc surface 4522 of the long convex rib 452 of the cover 45 of the adapter card 40 presses the second abutting inclined surface 33222 of the second hook 332 to push the second hook 332 away and release the second hook 332 from the cover 45, while the first block 3312 of the first hook 331 remains fixed to the cover 45 due to its longer protruding length. When the extension portion 322 of the first retaining member 32 abuts against the first limiting portion 312 of the main body 31, the first retaining member 32 can no longer pivot along the direction D1 and is positioned at the release position, and the retaining portion 323 of the first retaining member 32 has been released from the circuit board 41. At this time, only the first hook 331 of the adapter card holder 30 is still fixed to the cover 45 of the adapter card 40. The user only needs to apply force in the direction D2 to make the push arc surface 4522 of the long convex rib 452 of the cover 45 of the adapter card 40 press against the first abutting inclined surface 33122 of the first hook 331, so as to push the first hook 331 away and release the first hook 331 from the cover 45. In this way, the adapter card 40 can be removed from the adapter card holder 30.

[0104] Next, see Figure 4 , Figure 8 and Fig. 9 . Figure 8 and Fig. 9 Draw separately Figure 1 A partial cross-sectional schematic diagram and a side schematic diagram of the process of assembling the adapter card to the adapter card bearing seat.

[0105] When the user wants to install the adapter card 40 on the adapter card holder 30, the first fixing member 32 is first placed in the unlocked position to clear the installation path of the adapter card 40. Then, the positioning column 451 of the adapter card 40 is aligned with the positioning hole 317 of the main body 31, and the pushing inclined surface 4521 of the elongated convex rib 452 of the cover 45 of the adapter card 40 is pressed against the first pushed inclined surface 33121 of the first clamping block 3312 of the first hook 331 and the second pushed inclined surface 33221 of the second clamping block 3322 of the second hook 332, and one side of the circuit board 41 of the adapter card 40 is aligned with the pushing portion 324 of the first fixing member 32. Then, the adapter card 40 is pressed down along the direction D3, so that the elongated convex rib 452 of the cover 45 of the adapter card 40 pushes the first hook 331 and the second hook 332 away, and the first fixing member 32 is pivoted along the direction D4. Thus, after the positioning post 451 of the cover 45 of the riser card 40 is inserted into the positioning hole 317 of the main body 31, the first retaining member 32 is located at the locking position and is locked to the circuit board 41 of the riser card 40, and the first hook 331 and the second hook 332 are locked to the long rib 452 of the cover 45 of the riser card 40. Thus, the assembly operation of installing the riser card 40 on the riser card holder 30 is completed.

[0106] In this embodiment, the adapter card 40 is mounted on the main body 31 of the adapter card holder 30 and is fixed by the first retaining member 32 and the second retaining member 33 of the adapter card holder 30 which are asymmetrically arranged relative to the main body 31. Therefore, the adapter card 40 can be removed and assembled in a tool-free manner. Therefore, the operation time and tools required for screw installation and removal can be saved, the probability of damaging the adapter card 40 during screw installation and removal and the material cost of the screws can be reduced, and even if the space where the adapter card 40 is located is very narrow, the adapter card 40 can still be removed and assembled smoothly.

[0107] In addition, since the adapter card 40 is not fixed to the adapter card holder 30 by screws, the circuit board 41 of the adapter card 40 does not need to be provided with holes for screw assembly, so that the wiring area or the electronic component setting area on the circuit board 41 is not affected by the holes.

[0108] In addition, the main body 31 , the first retaining member 32 and the second retaining member 33 of the adapter card holder 30 may be made of recycled plastic material to meet the requirements of environmental friendliness, social responsibility and corporate governance (ESG).

[0109] In the present embodiment, when the first hook 331 and the second hook 332 of the second retaining member 33 are fixed to the elongated convex rib 452 of the cover body 45 of the adapter card 40, the configuration of the first abutting inclined surface 33122 of the first hook 331 and the second abutting inclined surface 33222 of the second hook 332 facing the pushing arc surface 4522 of the elongated convex rib 452 of the cover body 45 allows the first hook 331 and the second hook 332 to provide sufficient retaining force for the adapter card 40 while allowing the elongated convex rib 452 of the cover body 45 to easily push the first hook 331 and the second hook 332 away when the adapter card 40 is removed from the adapter card carrier 30, thereby facilitating the removal of the adapter card 40 from the adapter card carrier 30.

[0110] Furthermore, the combination of the pushing inclined surface 4521 of the elongated convex rib 452 of the cover body 45 of the adapter card 40, the first pushed inclined surface 33121 of the first hook 331, and the second pushed inclined surface 33221 of the second hook 332 allows the elongated convex rib 452 of the cover body 45 of the adapter card 40 to easily push the first hook 331 and the second hook 332 apart during the process of assembling the adapter card 40 on the adapter card carrier 30, thereby facilitating the assembly of the adapter card 40 on the adapter card carrier 30.

[0111] On the other hand, the length L1 of the second card block 3322 protruding from the second connecting arm 3321 is smaller than the length L2 of the first card block 3312 protruding from the first connecting arm 3311, so that the holding force provided by the second card block 3322 to the adapter card 40 is smaller than the holding force provided by the first card block 3312 to the adapter card 40, thereby ensuring that when the pushing portion 324 of the first retaining member 32 lifts one side of the adapter card 40, the second card block 3322 is first released from the adapter card 40, but the first card block 3312 remains fixed to the adapter card 40, temporarily maintaining the position of the other side of the adapter card 40.

[0112] It should be noted that the length L1 of the second block 3322 protruding from the second connecting arm 3321 is not limited to be less than the length L2 of the first block 3312 protruding from the first connecting arm 3311. In other embodiments, the length of the second block protruding from the second connecting arm may be equal to the length of the first block protruding from the first connecting arm.

[0113] On the other hand, the second hook 332 is an optional structure. In other embodiments, the second holder may not have the second hook, but only the first hook. In addition, the second holder 33 is not limited to the type of hook structure, but can be adjusted to other suitable structures according to needs. Furthermore, the second holder is not limited to the cover that can be detachably fixed to the adapter card. In other embodiments, the adapter card may not have a cover, and the second holder may be detachably fixed to the circuit board.

[0114] In this embodiment, the push portion 324 of the first retaining member 32 helps to lift the adapter card 40 when the first retaining member 32 is operated to remove the adapter card 40, and allows the adapter card 40 to drive the first retaining member 32 to pivot back to the fixed position during the assembly of the adapter card 40, thereby facilitating the assembly and disassembly of the adapter card 40. It should be noted that the push portion 324 of the first retaining member 32 is an optional structure and can be omitted.

[0115] In addition, the first retaining member 32 is not limited to being a pivotable element. In other embodiments, the first retaining member may be a non-pivotable element, but an elastically deformable element, so as to meet the requirement of being detachably fixed to the adapter card. In this way, the first limiting portion and the second limiting portion of the main body of the adapter card holder may be omitted accordingly.

[0116] On the other hand, the receiving groove 311 of the adapter card holder 30 is an optional structure and can be omitted.

[0117] Next, see Fig.10 and Fig.11 . Fig.10 It is an exploded schematic diagram of an adapter card and an adapter card supporting seat disclosed according to a second embodiment of the present invention. Fig.11 for Fig.10 A front view schematic diagram of an adapter card and an adapter card bearing seat.

[0118] The adapter card holder 30a of this embodiment is similar to the adapter card holder 30 of the above embodiment. The main difference between the two is that the matching structure between the second retaining member and the adapter card is different, and an elastic member is additionally provided on the first retaining member. The following mainly describes the difference between the adapter card holder 30a of this embodiment and the adapter card holder 30 of the above embodiment, and the same or similar structures between the two are not repeated.

[0119] In this embodiment, the second retaining member 33a of the adapter card holder 30a includes two snap-on elastic arms 331a. The two snap-on elastic arms 331a are separately connected to the main body 31a, and a snap-on slot 332a is formed between the two snap-on elastic arms 331a. The snap-on slot 332a has a narrow section 3321a and a wide section 3322a connected to each other, and the width W1 of the wide section 3322a is greater than the width W2 of the narrow section 3321a.

[0120] The adapter card 40a includes a circuit board 41a and a fastening member 46a. The fastening member 46a includes a head 461a and a body 462a connected to each other, and one end of the body 462a away from the head 461a is disposed on the circuit board 41a. The width W3 of the head 461a is greater than the width W4 of the body 462a and the width W1 of the wide section 3322a of the slot 332a, and the width W4 of the body 462a is greater than the width W2 of the narrow section 3321a of the slot 332a. The body 462a of the fastening member 46a is located in the wide section 3322a of the slot 332a, and the two snap spring arms 331a are located between the head 461a of the fastening member 46a and the circuit board 41a, so that the fastening member 46a can be detachably fastened to the slot 332a of the second retaining member 33a.

[0121] In this embodiment, the adapter card holder 30a further includes an elastic member 34a, and the extension portion 322a of the first retaining member 32a has an assembly groove 3221a. The elastic member 34a is, for example, a metal strip that can be elastically deformed. The opposite ends of the elastic member 34a are fixed to the main body 31a of the adapter card holder 30a, and a portion of the elastic member 34a is inserted into the assembly groove 3221a of the extension portion 322a of the first retaining member 32a. The elastic member 34a is used to apply a force to bias the first retaining member 32a toward the fixed position.

[0122] Next, see Fig.12 , Fig.12 for Fig.11 A front view schematic diagram of a first retaining member of an adapter card carrier.

[0123] When the user wants to remove the adapter card 40a from the adapter card holder 30a, the user can apply force to the retaining portion 323a of the first retaining member 32a along the direction D1, so that the first retaining member 32a pivots from the locking position to the release position, and the elastic member 34a accumulates elastic force. During the process of the first retaining member 32a pivoting toward the release position, the push portion 324a of the first retaining member 32a drives the adapter card 40a to pivot around the fastening member 46a, and lifts up one side of the circuit board 41a of the adapter card 40a. Then, the user can apply force along the direction D2, so that the body 462a of the fastening member 46a causes the two buckle elastic arms 331a to elastically deform outward, and break away from the restraint of the two buckle elastic arms 331a. In this way, the adapter card 40a is removed from the adapter card holder 30a.

[0124] On the contrary, when the user wants to install the adapter card 40a on the adapter card holder 30a, he first holds the first retaining member 32a by hand to place the first retaining member 32a in the unlocked position to make way for the installation path of the adapter card 40a. Then, the body 462a of the fastening member 46a of the adapter card 40a is aligned with the slot 332a of the second retaining member 33a. Then, the user can press down one side of the adapter card 40 along the direction D3 so that the body 462a of the fastening member 46a of the adapter card 40 is inserted into the slot 332a of the second retaining member 33a. Next, the other side of the adapter card 40a is pressed against the pushing portion 324a of the first retaining member 32a, and then the first retaining member 32a is released, allowing the elastic member 34a to automatically drive the first retaining member 32a to pivot from the release position to the locking position, thereby forcing the first retaining member 32a to lock the circuit board 41a of the adapter card 40a.

[0125] It should be noted that the elastic member 34a is an optional element and can be omitted or configured according to needs. In addition, in one embodiment, the elastic member can be configured on the first holding member 32 of the adapter card holder 30 of the above embodiment.

[0126] According to the server and the adapter card holder disclosed in the above embodiments, the adapter card is installed on the main body of the adapter card holder and is fixed by the first retaining member and the second retaining member of the adapter card holder that are asymmetrically arranged relative to the main body, so the adapter card can be removed and assembled in a tool-free manner. Therefore, the operation time and tools required for installing and removing screws can be saved, the probability of damaging the adapter card during the installation and removal of screws and the material cost of the screws can be reduced, and even if the space where the adapter card is located is very narrow, the installation and removal of the adapter card can still be carried out smoothly.

[0127] In addition, since the adapter card is not fixed to the adapter card support seat by screws, the circuit board of the adapter card does not need to be provided with holes for screw assembly, so that the wiring area or the electronic component setting area on the circuit board is not affected by the holes.

[0128] In addition, the main body, the first retaining member and the second retaining member of the adapter card holder can be made of recycled plastic materials to meet the requirements of environmental friendliness, social responsibility and corporate governance (ESG).
