Tray, mainboard module and server

Abstract

This application relates to a tray, a motherboard module, and a server. The tray includes a chassis and a mounting component. The chassis includes a first mounting area and a second mounting area, with the first mounting area used for the motherboard. The mounting component is disposed in the second mounting area and defines a mounting area for expansion cards along a first direction, the mounting area being located within the second mounting area. The technical solution of this application utilizes the space of the second mounting area to install expansion cards, while the tray independently provides a first mounting area for the motherboard. The installation of the expansion cards occupies only the space of the second mounting area, essentially not occupying the mounting space of the motherboard itself, and even less so the space of the motherboard. This not only helps improve the utilization rate of motherboard space, thus improving motherboard performance, but also reduces wear and tear on the motherboard during expansion card insertion and removal, lowering motherboard maintenance costs.

Technical Field

[0001] This application relates to the field of server technology, and in particular to trays, motherboard modules, and servers. Background Technology

[0002] Servers provide computing or application services to terminals such as PCs, smartphones, and ATMs on a network. Servers possess high-speed computing power, long-term reliable operation, and powerful data throughput capabilities. Existing servers mainly consist of a chassis, a motherboard, and various modules housed within the chassis. The motherboard, as the mainboard, serves to ensure the server's high stability, high performance, and high compatibility, and can be expanded with various expansion cards.

[0003] In related technologies, motherboards have mounting structures for expansion cards; the more expansion cards, the stronger the server's performance. However, these mounting structures occupy motherboard space, affecting motherboard layout and hindering performance improvements. Summary of the Invention

[0004] Therefore, it is necessary to provide a tray, motherboard module, and server to address the issue that expansion card insertion structures occupy motherboard space and are detrimental to motherboard performance improvement.

[0005] A tray, comprising:

[0006] The chassis includes a first mounting area and a second mounting area, wherein the first mounting area is used to mount the motherboard; and

[0007] An insertion component is disposed in the second mounting area and defines an insertion area for inserting an expansion card along a first direction, the insertion area being located within the second mounting area.

[0008] In some embodiments, the insertion assembly includes two insertion rails, each of which extends along the first direction and is disposed in the second mounting area, and the two rails are spaced apart along a second direction intersecting the first direction and enclosing the insertion area.

[0009] In some embodiments, each of the insert rails is provided with an insert groove, the insert groove being disposed through the first direction, and the openings of the insert grooves of the two insert rails being disposed opposite each other in the second direction.

[0010] In some embodiments, the chassis includes two bending strips disposed in the second mounting area and spaced apart in the second direction;

[0011] Each of the aforementioned bending strips extends along the first direction and is bent along the second direction to form a fixing groove that opens toward each other;

[0012] The two insertion rails are respectively inserted into the two fixing slots.

[0013] In some embodiments, the tray includes a connector that securely connects the bending strip to the insert rail.

[0014] In some embodiments, one of the bending strip and the insert rail has a positioning recess and the other has a positioning protrusion, and the bending strip and the insert rail are positioned and engaged via the positioning recess and the positioning protrusion.

[0015] In some embodiments, the insertion assembly further includes a locking structure disposed on the insertion rail for locking the expansion card to the insertion rail.

[0016] In some embodiments, the insert rail has an insert slot, and the locking structure includes a locking member; the locking member is switchable relative to the insert rail between a locked position extending into the insert slot and an unlocked position exiting the insert slot.

[0017] In some embodiments, the locking structure further includes an operating element, and the insert rail has a mounting hole communicating with the insert slot;

[0018] The locking element is movably disposed in the mounting hole, and the operating element is located outside the insertion rail and is capable of driving the locking element to switch between the locked position and the unlocked position when moving.

[0019] In some embodiments, the locking structure further includes an adapter shaft that rotatably connects the operating member and the locking member.

[0020] In some embodiments, the mounting hole includes a first hole segment and a second hole segment coaxially disposed, the second hole segment communicating between the first hole segment and the insertion slot;

[0021] The locking member has a locking end facing the insertion slot, and the locking structure further includes an elastic member, which is sleeved on the locking member and located within the second hole segment and elastically abuts against the locking end.

[0022] A motherboard module, comprising:

[0023] Motherboard; and

[0024] As described in any of the preceding claims, the motherboard is mounted in the first mounting area of ​​the tray.

[0025] In some embodiments, the motherboard module further includes an expansion card;

[0026] The insertion assembly includes a locking structure and an insertion rail, the insertion rail having an insertion slot, and the locking structure disposed on the insertion rail;

[0027] The expansion card is provided with a locking recess, and when the expansion card is inserted into the insertion slot, the locking recess can be locked with the locking member of the locking structure.

[0028] A server, comprising:

[0029] Chassis; and

[0030] The motherboard module as described in any of the above claims is housed within the chassis.

[0033] The end plate has a clamping part, which is pressed against the end of the insertion rail near the insertion port.

[0034] The aforementioned tray, motherboard module, and server place the expansion card mounting components in the second mounting area of ​​the tray. The expansion cards are installed using the space in the second mounting area, while the tray independently provides a first mounting area for the motherboard. The installation of the expansion cards occupies the space in the second mounting area and does not occupy the mounting space of the motherboard itself, let alone the space of the motherboard. This not only helps to improve the utilization rate of the motherboard space, thereby improving the performance of the motherboard, but also reduces the wear and tear on the motherboard during the expansion card insertion and removal process, thus reducing the maintenance cost of the motherboard.

[0055] This application addresses the problem that expansion card insertion structures occupy motherboard space, which is detrimental to improving motherboard performance, and proposes a tray, motherboard module, and server.

[0056] The server provided in this application embodiment, depending on its product form, can be a rack server, tower server, blade server, cabinet server, etc. Depending on its instruction set architecture, the server can be a CISC (Complex Instruction Set Computing) server, a RISC (Reduced Instruction Set Computing) server, or an EPIC (Explicitly Parallel Instruction Computing) server. Depending on the number of processors, the server can be a single-socket server, a dual-socket server, a quad-socket server, an eight-socket server, etc.

[0057] Typically, a server includes a motherboard, and hard drive modules, a central processing unit (CPU), memory modules, a power supply module, I / O modules, a GPU module, etc., all electrically connected to the motherboard. The configuration of each module and the motherboard is conventional in the field and will not be elaborated upon. The expansion cards mentioned in the embodiments of this application may be, but are not limited to, network cards, TV cards, video capture cards, sound cards, graphics cards, etc.

[0058] The tray, motherboard module, and server provided in the embodiments of this application will be described in detail below.

[0059] Figure 1 This is a partial structural diagram of a server 1000 according to some embodiments. Figure 2 This is a partial structural diagram of a server 1000 in some other embodiments.

[0060] According to some embodiments of this application, please refer to Figure 1 and Figure 2 The server 1000 provided in this application embodiment includes a chassis 200 and a motherboard module 100. The motherboard module 100 is housed within the chassis 200. The chassis 200 is the outer frame structure of the server 1000, mainly used to house and protect various functional devices within the server 1000, and can expose various ports for connecting to external data / power cables. Typically, but not limited to, the chassis 200 is made of plastic. Typically, the chassis 200 includes a housing and a cover plate, the housing forming a cavity for accommodating various functional devices, and the cover plate closing onto the opening end of the cavity.

[0061] In some embodiments, the motherboard module 100 includes a motherboard 20 and a tray 10, with the tray 10 supporting the motherboard 20 and the motherboard 20 mounted on the tray 10. Typically, the motherboard 20 is securely and detachably mounted on the tray 10. The tray 10 can be securely connected to the chassis 200, or it can be plugged in, etc. The tray 10 can be a metal tray, a plastic tray, etc. The motherboard 20 is a core component of the server 1000, and its main function is to transmit various electronic signals. For the specific structure of the motherboard 20, please refer to the conventional configuration; details will not be elaborated here.

[0062] The tray 10 in the server 1000 of this application embodiment will be described in detail below.

[0063] Please refer to Figures 1 to 2 In some embodiments, tray 10 includes chassis 11 and insertion assembly 12. Chassis 11 includes a first mounting area Q1 and a second mounting area Q2, the first mounting area Q1 being used for motherboard 20. Insertion assembly 12 is disposed in the second mounting area Q2 and defines an insertion area K for inserting expansion card 30 along a first direction X, the insertion area K being located within the second mounting area Q2.

[0064] The chassis 11 is the main body that supports the motherboard 20, and it is divided into at least a first mounting area Q1 and a second mounting area Q2. The first mounting area Q1 is used to mount the motherboard 20, and the shape of the first mounting area Q1 can be adapted to the outer contour shape of the motherboard 20. The base plate is set on the chassis 200 and can be fixedly connected to the chassis 200. The specific connection method can be, but is not limited to, fastening connection, plug-in connection, etc.

[0065] The insertion component 12 is located in the second mounting area Q2 of the chassis 11, separate from the first mounting area Q1, and does not occupy the mounting space of the motherboard 20. The insertion component 12 defines an insertion area K for inserting the expansion card 30 along the first direction X, and the insertion area K is located within the range of the second mounting area Q2. In practical applications, the expansion card 30 can be inserted into the insertion area K along the first direction X, realizing the quick installation of the expansion card 30, and the expansion card 30 basically falls within the range of the second mounting area Q2 under the restriction of the insertion area K.

[0066] The insertion assembly 12 primarily serves to guide the tool-less insertion of the expansion card 30 into the chassis 200 and to support the expansion card 30. The insertion assembly 12 defines an insertion area K, which can be an insertion plane area. For example, the insertion assembly 12 includes an insertion plate, which constitutes the insertion area K. Corresponding slides, tracks, or other structures for inserting the expansion card 30 along the first direction X can be provided on the insertion plate. The insertion area K can also be an insertion hole. For example, the insertion assembly 12 includes an insertion box with an insertion hole extending along the first direction X, into which the expansion card 30 can be inserted. The expansion card 30 is essentially accommodated within the insertion area K; at least in the projection onto the plane of the motherboard 20, the expansion card 30 is essentially located within the insertion area K.

[0067] Understandably, after the expansion card 30 is inserted into the insertion assembly 12, its connector 31 can be inserted into the corresponding expansion slot 21 on the motherboard 20 to achieve electrical connection between the two. By using the insertion assembly 12 to support part of the weight of the expansion card 30, the insertion reliability and service life of the expansion card 30 into the expansion slot 21 on the motherboard 20 can be improved.

[0068] Understandably, the motherboard 20 is roughly flat. Typically, the first direction X is parallel to the plane where the motherboard 20 is located. Specifically, the chassis 200 may have an end plate 210, which provides a slot 211 for installing an expansion card 30. The first direction X can be the direction of the chassis 200 where the end plate 210 is located, such as the front-to-back direction.

[0069] In the technical solution of this application, the insertion component 12 of the expansion card 30 is set in the second installation area Q2 of the tray 10. The expansion card 30 is installed using the space of the second installation area Q2. The tray 10 independently provides the first installation area Q1 for installing the motherboard 20. The installation of the expansion card 30 occupies the space of the second installation area Q2, and basically does not occupy the installation space of the motherboard 20, let alone the space of the motherboard 20 itself. This not only helps to improve the space utilization of the motherboard 20 and thus improve the performance of the motherboard 20, but also reduces the wear and tear on the motherboard 20 during the insertion and removal of the expansion card 30, and reduces the maintenance cost of the motherboard 20.

[0070] Figure 3 for Figure 1 The diagram shown is an exploded view of server 1000.

[0071] In some embodiments, please refer to Figures 1 to 3 The insertion assembly 12 includes two insertion rails 12a, each of which extends along a first direction X, and the two are arranged at intervals along a second direction Y that intersects the first direction X and enclose an insertion area K.

[0072] The second direction Y is approximately perpendicular to the first direction X. Typically, the first direction X is the length direction of the expansion card 30, and the second direction Y is the width direction of the expansion card 30.

[0073] The expansion card 30 has two sides (defined as insertion edges) in its width direction that are respectively inserted into two insertion rails 12a along the first direction X. Understandably, the insertion edges of the expansion card 30 and the insertion rails 12a can be, but are not limited to, a recessed-protrusion engagement. Specifically, one of the insertion edges and the insertion rails 12a has an insertion recess, and the other has an insertion protrusion, and both the insertion recess and the insertion protrusion extend along the first direction X and are disposed in the second mounting area Q2. For example, the insertion recess and the insertion protrusion can be recessed-protrusion mating in a third direction Z (which can be the thickness direction of the expansion card 30) that is perpendicular to both the first direction X and the second direction Y.

[0074] Two insertion rails 12a are spaced apart and enclosed to form an insertion area K. This insertion area K can be located on one side of the two insertion rails 12a in the third direction Z, and extends in the second direction Y from the area where one insertion rail 12a is located to the area where the other insertion rail 12a is located. That is, the expansion card 30 can be supported on the insertion rails 12a. The insertion area K can also be located within the range defined by the height of the two insertion rails 12a themselves in the third direction Z, that is, the expansion card 30 can be accommodated between the two insertion rails 12a.

[0075] At this time, the expansion card 30 is inserted using two insertion rails 12a. The insertion assembly 12 has a simple structure and low manufacturing cost.

[0076] For specific embodiments, please refer to Figures 1 to 3 Each insertion rail 12a is provided with an insertion groove a1, which is arranged through the first direction X. The groove openings of the insertion grooves a1 of the two insertion rails 12a are arranged opposite each other in the second direction Y.

[0077] The insertion slot a1 engages with the insertion edge of the expansion card 30, accommodating and guiding the insertion edge of the expansion card 30 to be inserted into the insertion rail 12a along the first direction X. The opening of the insertion slot a1 is located on the second direction Y of the insertion rail 12a, and the openings of the insertion slots a1 of the two insertion rails 12a are arranged opposite each other to facilitate the installation of the expansion slot and to accommodate the expansion card 30 in the space area located between the two insertion slots a1 and the space between them, which is the insertion area K.

[0078] At this time, the insertion slots a1 of the insertion rails 12a are arranged opposite to each other. When the expansion card 30 is inserted into the insertion rail 12a along the insertion slot a1, the expansion card 30 is housed in the space in the third direction Z where the two insertion rails 12a are located. The insertion rails 12a have good housing performance for the expansion card 30. In the second direction Y, the expansion card 30 is completely located within the second installation area Q2 where the two insertion rails 12a are located. This can prevent the expansion card 30 from extending into the space of the first installation area Q1 in the first direction X, thereby increasing the installation space of the motherboard 20 and thus improving the performance of the motherboard 20.

[0079] For specific embodiments, please refer to Figures 1 to 3 The chassis 11 includes two bent strips 11b, which are disposed in the second mounting area Q2 and spaced apart in the second direction Y. Each bent strip 11b extends along the first direction X and is bent along the second direction Y to form a fixing groove b1 that opens toward each other. Two insert rails 12a are respectively inserted into the two fixing grooves b1.

[0080] Specifically, the bending strip 11b includes a first part and a second part. The first part is disposed on the chassis 11 of the second mounting area Q2. The second part is bent relative to the first part and spaced apart from the chassis 11. The second part, the first part and the chassis 11 together form a fixing groove b1. The fixing groove b1 extends along the first direction X and the groove opening is located in the second direction Y.

[0081] The slots (i.e. openings) of the two fixing slots b1 are arranged opposite each other. Each insert rail 12a can be installed by inserting it into the fixing slot b1 from the slot opening of one fixing slot b1 or by inserting it into the fixing slot b1 along the first direction X.

[0082] At this time, the insert rail 12a is installed using the fixing groove b1. The fixing groove b1 can be used to position and limit the insert rail 12a, making the installation of the insert rail 12a on the chassis 11 easier.

[0083] Further in the embodiments, please refer to Figures 1 to 3 The tray 10 includes a connector 13, which securely connects the bent strip 11b to the insert rail 12a.

[0084] The connector 13 can be a bolt, pin, screw, rivet, pin, etc. Specifically, a connecting hole 13c can be provided on the bent strip 11b and the insert rail 12a, and the bent strip 11b and the insert rail 12a can be fixedly connected by the connector 13 passing through the connecting hole 13c.

[0085] At this point, the bent strip 11b and the insert rail 12a are fixedly connected by the connector 13. The structure is simple, the cost is low, and it is convenient to maintain and replace the insert rail 12a.

[0086] Of course, in other embodiments, the bending strip 11b and the insert rail 12a can also be connected by welding, hot-melt connection, magnetic connection, etc.

[0087] Further in the embodiments, please refer to Figures 1 to 3 One of the bent strip 11b and the insert rail 12a has a positioning recess d1 and the other has a positioning protrusion d2. The bent strip 11b and the insert rail 12a are positioned and engaged via the positioning recess d1 and the positioning protrusion d2.

[0088] exist Figures 1 to 3 In the illustrated embodiment, the bent strip 11b has a positioning recess d1, specifically a positioning hole. The insert rail 12a has a positioning protrusion d2, specifically a positioning post. When installing the insert rail 12a, during the process of inserting the insert rail 12a into the fixing groove b1 of the bent strip 11b through the groove opening, the positioning protrusion d2 of the insert rail 12a is aligned with the positioning recess d1 of the bent strip 11b. After the insert rail 12a is inserted into place, the bent strip 11b and the insert rail 12a are fixed by the connector 13, thus completing the installation of the insert rail 12a.

[0089] At this time, the positioning protrusion d2 and the positioning recess d1 can be used to position the insert rail 12a and the bent strip 11b, which facilitates the setting of the connector 13 and can also quickly determine the installation position of the insert rail 12a in the second installation area Q2.

[0090] Figure 4 This is a schematic diagram of the installation of the locking structure 14 and the insert rail 12a in some embodiments. Figure 5 for Figure 4 A schematic diagram of the internal structure of the structure shown. Figure 6 for Figure 4 A partial schematic diagram of the structure shown.

[0091] In some embodiments, please refer to Figure 3 and combined Figures 4 to 6 The insertion assembly 12 also includes a locking structure 14, which is disposed on the insertion rail 12a and is used to lock the expansion card 30 to the insertion rail 12a.

[0092] The locking structure 14 is a structure that locks the expansion card 30 onto the insertion rail 12a. It can be, but is not limited to, a locking magnet, a locking bolt, a locking plate, etc. Any structure that can maintain the stable position of the expansion card 30 on the insertion rail 12a is acceptable.

[0093] At this time, using the locking structure 14 to lock the expansion card 30 onto the insertion rail 12a can reduce the probability of expansion card detachment and improve the installation reliability of the expansion card 30.

[0094] For specific implementation examples, please refer to Figure 3 and combined Figures 4 to 6 The insertion rail 12a has an insertion slot a1, and the locking structure 14 includes a locking member 14e, which can switch between a locked position extending into the insertion slot a1 and an unlocked position exiting the insertion slot a1 relative to the insertion rail 12a.

[0095] Correspondingly, the expansion card 30 is provided with a locking recess 32, which can lock with the locking member 14e when the expansion card 30 is inserted into the insertion slot a1.

[0096] The locking element 14e can be a locking lever, locking shaft, locking block, etc. The locking element 14e is movably mounted on the insertion rail 12a, and its movability can be either movement or rotation. The locking element 14e has two positions during its movement: a locked position and an unlocked position. When in the locked position, the locking element 14e extends into the insertion slot a1; when in the unlocked position, the locking element 14e disengages from the insertion slot a1.

[0097] When installing the expansion card 30, first switch the locking member 14e to the unlocked position. At this time, the expansion card 30 can be inserted into the insertion rail 12a along the insertion slot a1. After the expansion card 30 is inserted, switch the locking member 14e to the locked position. At this time, the locking member 14e extends into the insertion slot a1, and the portion of the locking member 14e within the insertion slot a1 can precisely engage with the locking recess 32 of the expansion card 30, thus achieving locking between the locking member 14e and the locking recess 32. The locking recess 32 can be a recessed hole, groove, etc.

[0098] At this time, the expansion card 30 is fixed to the insertion rail 12a by the cooperation of the locking member 14e and the locking recess 32, which is convenient to operate and occupies less space. The insertion component 12 has a more compact structure, which can reduce the space size of the second installation area Q2 and increase the space size of the first installation area Q1, thereby helping to improve the performance of the motherboard 20.

[0099] Regarding the configuration of the locking member 14e on the insertion rail 12a, for example, the locking member 14e is disposed at one end of the insertion rail 12a in the first direction X, and the locking recess 32 on the expansion card 30 is recessed at one end of the expansion card 30 along the first direction X. When the locking member 14e is in the locked position, it can be inserted into the insertion slot a1 and simultaneously extend into the locking recess 32. Of course, the configuration of the locking member 14e on the insertion rail 12a can also adopt the following embodiment.

[0100] Further in the embodiments, please refer to Figure 3 and combined Figures 4 to 5 The locking structure 14 also includes an operating member 14f. The insert rail 12a has a mounting hole a2 communicating with the insert slot a1. The locking member 14e is movably disposed in the mounting hole a2. The operating member 14f is located outside the insert rail 12a and can drive the locking member 14e to switch between a locked position and an unlocked position when moving.

[0101] The mounting hole a2 is provided in an axial direction that is approximately perpendicular to the first direction X. Figures 4 to 6 In this embodiment, the axial direction of the mounting hole a2 is approximately parallel to the third direction Z. The locking member 14e is movably disposed within the mounting hole a2 along the third direction Z.

[0102] The operating element 14f is operated by the user and can drive the locking element 14e to move along the mounting hole a2 under the action of external force. The locking element 14e switches between the unlocked position and the locked position when moving.

[0103] At this point, the movement configuration of the locking element 14e is simple and easy to implement, and the setting of the operating element 14f is convenient for maintenance personnel to operate.

[0104] Further in the embodiments, please refer to Figure 3 and combined Figures 4 to 6The locking structure 14 also includes a transition shaft 14h, which rotatably connects the operating member 14f and the locking member 14e. Specifically, the transition shaft 14h is rotatably connected to both the operating member 14f and the locking member 14e. In actual operation, the maintenance personnel can rotate the operating member 14f along the abutment position (i.e., the rotating bracket) where it abuts against the insertion rail 12a. Driven by the transition shaft 14h, the locking member 14e moves along the mounting hole a2. In this way, the maintenance personnel can rotate the operating member 14f along the pivot point, making the operation more labor-saving.

[0105] Further in the embodiments, please refer to Figure 5 The mounting hole a2 includes a first hole segment a21 and a second hole segment a22 coaxially arranged, with the second hole segment a22 communicating with the first hole segment a21 and the insertion slot a1. The locking member 14e has a locking end e1 facing the insertion slot a1, and the locking structure 14 also includes an elastic member 14g, which is sleeved on the locking member 14e, located inside the second hole segment a22, and elastically abuts against the locking end e1.

[0106] The locking end e1 can move along the second hole segment a22 without entering the first hole segment a21, and the area of ​​its cross section perpendicular to the third direction Z is larger than the portion of the locking member 14e located in the first hole segment a21.

[0107] The diameter of the first hole section a21 is smaller than that of the second hole section a22 and the two are coaxial. The locking end e1 and the elastic element 14g will not come out of the second hole section a22 and enter the first hole section a21. That is, the first hole section a21 and the second hole section a22 form a stepped hole.

[0108] The elastic element 14g can be, but is not limited to, a spring, a rubber ring, or a silicone ring. It can elastically deform in the moving direction of the locking element 14e. One end of it abuts against the inner wall of the second hole section a22, and the other end abuts against the locking end e1. When the operating element 14f drives the locking element 14e to move along the mounting hole a2 toward the outside of the insertion slot a1, the locking end e1 can compress the elastic element 14g. When the external force on the operating element 14f is removed, under the action of the restoring force of the elastic element 14g, the locking end e1 moves toward the insertion slot a1, and the locking end e1 can extend into the locking recess 32.

[0109] At this time, the locking end e1 can be tightly set in the locking recess 32 by using the elastic element 14g, which improves the locking reliability between the locking element 14e and the expansion card 30.

[0110] Figure 7 for Figure 2 Enlarged view of point I in the middle.

[0111] In some embodiments, please refer to Figure 7The chassis 200 includes an end plate 210, which has an insertion port 211 located on one side of the insertion assembly 12 in the first direction X. The insertion assembly 12 includes an insertion rail 12a, and the end plate 210 has a clamping part 212, which is pressed against the end of the insertion rail 12a near the insertion port 211.

[0112] The insertion port 211 connects the inside and outside of the chassis 200, and the expansion card 30 is inserted into the insertion assembly 12 through the insertion port 211. The clamping part 212 can be located inside or outside the insertion port 211. The clamping part 212 and the end plate 210 can be integrally formed or separately set.

[0113] The clamping part 212 is pressed against the end of the insertion rail 12a near the insertion port 211, which can prevent one end of the insertion rail 12a from warping, help improve the straightness of the insertion rail 12a, and thus improve the smoothness of the insertion of the expansion card 30. At the same time, by clamping the insertion rail 12a with the clamping part 212, it can also reduce or even prevent one side of the tray 10 installed in the chassis 200 from warping, limit the position of the tray 10, and improve the installation reliability of the tray 10.

[0114] In one embodiment of this application, the server 1000 includes a motherboard 20, a tray 10, an expansion card 30, and a chassis 200. The tray 10 includes a chassis 11 and a mounting assembly 12. The motherboard 20 is mounted in a first mounting area Q1 of the chassis 11, and the mounting assembly 12 is mounted in a second mounting area Q2 of the chassis 11. The mounting assembly 12 includes two mounting rails 12a, two bending strips 11b, and a locking structure 14. Each mounting rail 12a has a mounting slot a1. The two mounting rails 12a are spaced apart in the second direction Y and enclose a mounting area K. The chassis 200 includes an end plate 210, which has a mounting port 211. The expansion card 30 is inserted into the mounting slot a1 along the first direction X via the mounting port 211 and into the mounting area K. The bending strips 11b form a fixing groove b1, and the mounting rails 12a are partially fitted into the fixing groove b1. The locking structure 14 is provided on the insertion rail 12a and can lock the expansion card 30 onto the insertion rail 12a. The end plate 210 is provided with a pressing part 212, which is pressed against the end of the insertion rail 12a near the insertion port 211.

[0115] Furthermore, expansion card 30 is a network card.

[0116] In addition, the motherboard module 100 provided in this application embodiment includes the motherboard 20 and the tray 10 in any of the above embodiments, and has all the above-mentioned beneficial effects, which will not be repeated here.
