[0067] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0068] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0069] Please refer to Figure 1 and Figure 9The server provided by the embodiment of the present invention includes a chassis 10 and a board module 20.

[0070] The chassis 10 includes a box body 11 and a beam 12. The beam 12 is installed in the box body 11 along a first direction, so that the inner cavity of the box body 11 is constructed as a first accommodating cavity 111 and a second accommodating cavity 112 respectively located on both sides of the beam 12 along a second direction, wherein the second direction is perpendicular to the first direction.

[0071] The first direction can be as follows Figure 1 The Z-axis direction shown, the second direction can be as follows Figure 1 The X-axis direction is shown.

[0072] The board module 20 is installed in the chassis 10. The board module 20 includes a baseboard 21, a network card 22 and an expansion card. The baseboard 21 adopts an integrally formed structure. The baseboard 21 is detachably connected to the box body 11. The baseboard 21 is located below the beam 12. The network card 22 and the expansion card are both installed on the baseboard 21. The network card 22 and the expansion card are respectively accommodated in the first accommodating cavity 111 and the second accommodating cavity 112, and the network card 22 is fixed to the beam 12.

[0073] Considering the sizes of the network card 22 and the expansion card along the second direction, the size of the second accommodating cavity 112 along the second direction is set to be larger than the size of the first accommodating cavity 111 along the second direction.

[0074] When assembling the above-mentioned server, first, fix the base plate 21 in the box body 11, then fix the beam 12 in the box body 11, and make the beam 12 be above the base plate 21, then, plug the network card 22 and the expansion card into the base plate 21, and fix the network card 22 to the beam 12, when the expansion card is a first-form expansion card 23, then fix the first-form expansion card 23 to the beam 12, when the expansion card is a second-form expansion card 24, then fix the second-form expansion card 24 to the base plate 21.

[0075] It should be noted that the server provided by the application can be a GPU (English full name: Graphics Processing Unit, Chinese abbreviation: graphics processor) server, and the expansion card in the application is also called an adapter card or a plug-in card, which is a hardware device that can be inserted into the expansion slot of the mainboard, used to increase or enhance the function of the server, and accordingly, the expansion card can adopt a GPU card, and the first mode expansion card 23 can be a PCIe (also known as PCI-Express, English full name: peripheral component interconnect express, a high-speed serial computer expansion bus standard) mode GPU card, and the second mode expansion card 24 can be an OAM (English full name: Open Accelerator Module, a standardized module form for AI accelerator) mode GPU card.

[0076] Among them, the PCIe mode GPU card is connected to the PCIe connector on the substrate 21 through the gold finger, and is used to transmit the signal data of the GPU card operation; the OAM mode GPU card usually integrates some management and monitoring functions, which are used to monitor the running state, temperature, voltage and other parameters of the server, and provide remote management function. According to different GPU modes, the substrate 21 can be designed as a substrate suitable for PCIe mode GPU card or a substrate suitable for OAM mode GPU card.

[0077] In addition, the network card 22, that is, the network interface card, is a hardware device used to realize network connection, and the network card 22 is connected to the substrate 21, allowing the server to be connected to the network for data transmission.

[0078] In the GPU server system, the traditional substrate 21 adopts a split type substrate structure connected by a switching board and a mainboard, that is, the traditional substrate 21 adopts a switching board and a mainboard connected by two boards, and the switching board and the mainboard are assembled and connected by a row of high-density connectors, cables, guide columns and guide sleeves, and a power wrench, etc. In this architecture, the switching board needs to be designed as a separate detachable frame, and because the switching board and the mainboard are interconnected by high-density connectors, the plug-in force of the connector is very large, and a power wrench needs to be designed to assemble the switching board frame into the server system.

[0079] Therefore, the power wrench is arranged on both sides of the case 10, and when the detachable frame where the switching board is located is installed into the server system, the power wrench located on the inner wall of the server case 10 is rotated by an angle, and then the detachable frame is pushed in, and the inner wall of both sides of the case 10 is provided with a slide and a stop feature, and the clamps of the detachable frame are clamped into the wrench opening slot, and by using the lever principle, the detachable frame can be assembled into place by rotating the wrench.

[0080] The server system has high cost, complex structure, difficult assembly and high failure rate.

[0081] Compared with the traditional substrate 21 adopting the exchange board and the main board, the substrate 21 of the application adopts an integrated structure, that is, the exchange board and the main board are combined into one substrate 21. In this way, the high-density connector, the guide column and the guide sleeve required when connecting the exchange board and the main board are cancelled, and the production cost, including the material cost and the labor cost of assembly, can be saved.

[0082] Compared with the traditional exchange board which needs to be assembled into the exchange board frame and then assembled into the system, and needs to be designed with a helper wrench and other auxiliary installation, after the main board and the exchange board are combined into one substrate 21, the substrate 21 can be assembled into the box body 11 at one time, and the detachable frame where the exchange board is located does not need to be assembled again. Not only the complex structure such as the helper wrench is cancelled, but also the overall structure of the server is simplified, and the difficulty of assembly and the failure rate after assembly are reduced.

[0083] In addition, the box 10 provided by the application has sufficient space and appropriate fixing mechanism inside to adapt to two forms of expansion cards, that is, the box 10 can be compatible with the PCIe form expansion card and the OAM form expansion card. When assembling, if the second form connector of the substrate 21 is replaced by the first form connector, the box 10 can be compatible with the first form expansion card 23. At this time, the box 10 inside is adapted to the first form expansion card 23. This design allows users to choose the most suitable expansion card according to actual application needs and budget, without worrying about the compatibility of the box 10, that is, the expansion card does not need to replace the entire box 10. In this way, the flexibility and compatibility of the box 10 can be increased to adapt to the needs of different users.

[0084] Please refer to Figure 2 and Figure 3 , the cross beam 12 includes a beam body 121 and a connecting plate 122, the connecting plate 122 is arranged on the side of the beam body 121 away from the expansion card, the connecting plate 122 extends in the horizontal direction, and the connecting plate 122 is used for connecting the network card 22 to facilitate fixing the network card 22.

[0085] Specifically, the connecting plate 122 is provided with a first connecting hole 1221, and correspondingly, the network card 22 is connected with a first fixing frame 221, the first fixing frame 221 is provided with a second connecting hole 22121, and the second connecting hole 22121 and the first connecting hole 1221 are aligned and connected through a first connecting piece 222, so that the first fixing frame 221 is fixed to the connecting plate 122.

[0086] Among them, the first connecting hole 1221 can be a screw hole, the second connecting hole 22121 is a through hole or a light hole, and the first connecting member 222 is a connecting screw. In this way, the first connecting member 222 passes through the second connecting hole 22121 and is screwed into the first connecting hole 1221, so that the first fixing frame 221 is fixed to the connecting plate 122.

[0087] Please also refer to Figure 4 The first fixing frame 221 includes a first fixing plate 2211, a first hole plate 2212 and a second hole plate 2213. The first fixing plate 2211 is in the shape of a hollow triangular plate. The first hole plate 2212 and the second hole plate 2213 are respectively arranged at the two ends of the first fixing plate 2211 along the second direction, and the first hole plate 2212 and the second hole plate 2213 are arranged on the same side of the first fixing plate 2211. The first hole plate 2212 is provided with a second connecting hole 22121, and the second hole plate 2213 is provided with two third connecting holes 22131 distributed at intervals along the first direction. The axis of the second connecting hole 22121 is along the first direction, and the axes of the two third connecting holes 22131 are both along the second direction. Therefore, the axis of the second connecting hole 22121 is perpendicular to the axis of the third connecting hole 22131. The third connecting hole 22131 is used to connect the second connecting member 223, so that the first fixing frame 221 is fixed to the network card 22.

[0088] Of course, according to actual needs, the second connecting member 223 can also be a connecting screw. The second connecting member 223 passes through the third connecting hole 22131 and is screwed to the network card 22 to fix the first fixing bracket 221 to the side of the network card 22 close to the expansion card.

[0089] When installing the network card 22, first fix the first fixing frame 221 to the network card 22, then plug the network card 22 into the base plate 21, and then connect and fix the first fixing frame 221 and the connecting plate 122 on the beam 12 with connecting screws to ensure the installation stability of the network card 22.

[0090] Of course, the number of the first connection holes 1221 on the connection plate 122 can be determined according to the number of network cards 22 actually to be assembled.

[0091] To facilitate the fixing of the crossbeam 12, guide grooves 1211 are provided at both ends of the beam body 121. The guide grooves 1211 extend along the first direction. Correspondingly, a guide member is provided in the box body 11. The guide member can be a guide plate or a guide nail. The guide member slides in conjunction with the guide grooves 1211 so that the crossbeam 12 is installed in the box body 11 along the first direction.

[0092] That is to say, when the cross beam 12 is assembled downward in the box body 11, the guiding effect of the guide and the guide groove 1211 can not only prevent the cross beam 12 from being deviated in position and ensure that the cross beam 12 is assembled in place downward, but also the guide and the guide groove 1211 have the effect of plugging, so that the cross beam 12 is positioned and assembled in the box body 11.

[0093] Furthermore, on the basis of the guiding plugging of the cross beam 12 and the box body 11 through the guide and the guide groove 1211, the cross beam 12 and the box body 11 can be further connected through the third connecting piece 123.

[0094] Specifically, the connecting plate 122 is bent upward at both ends in the third direction to form the flaps 1222, so that the connecting plate 122 and the flaps 1222 at both ends form a U-shaped plate body structure, the flaps 1222 and one end of the corresponding beam body 121 are provided with at least three fourth connecting holes 1212, and the box body 11 is provided with through holes 113 corresponding to the fourth connecting holes 1212 one by one. After the fourth connecting holes 1212 and the corresponding through holes 113 are aligned, the third connecting piece 123 is connected to fix the cross beam 12 in the box body 11.

[0095] It should be noted that the third direction, the second direction and the first direction are perpendicular to each other, and the third direction is the Y-axis direction as shown in Figure 1 .

[0096] Among them, the fourth connecting hole 1212 can be a screw hole, and the third connecting piece 123 is a connecting screw, so that the third connecting piece 123 is screwed into the fourth connecting hole 1212 after passing through the through hole 113 on the box body 11, so that the cross beam 12 is fixed in the box body 11.

[0097] For example, one fourth connecting hole 1212 can be arranged on the flap 1222, and two fourth connecting holes 1212 can be arranged at the end of the corresponding beam body 121. After the three fourth connecting holes 1212 are screwed into the connecting screws, a stable three-point connection structure is formed, so as to ensure the stability and firmness of the connection between the cross beam 12 and the box body 11.

[0098] In addition, the bottom of the cross beam 12 is provided with at least two supporting legs 124, and the at least two supporting legs 124 are spaced apart along the third direction. The supporting leg 124 is L-shaped, and the supporting leg 124 is connected with the box body 11 through the fourth connecting piece 125. The fourth connecting piece 125 is specifically a non-releasable screw.

[0105] In this way, when assembling the first form expansion card 23, the second fixing frame 231 can be fixed on the first form expansion card 23 through the seventh connecting hole 23131 first, then the first form expansion card 23 fixed with the second fixing frame 231 is plugged on the substrate 21, and then the second fixing frame 231 is fixed and connected on the beam body 121, so as to ensure the installation stability of the first form expansion card 23.

[0106] In addition, the case 10 further comprises a support 13, which is installed on the side of the crossbeam 12 away from the network card 22, and the distance between the support 13 and the crossbeam 12 should be equal to or slightly greater than the size of the first-form expansion card 23 along the second direction, so as to facilitate the assembly of the first-form expansion card 23 between the crossbeam 12 and the support 13.

[0107] Please refer to Figure 5 and Figure 8 , in order to facilitate the connection of the support 13 and the first-form expansion card 23, the support 13 is provided with a positioning convex 131 (or a positioning convex bridge) and an eighth connecting hole 132, and correspondingly, the side of the first-form expansion card 23 away from the second fixing frame 231 is further connected with a baffle 233, the baffle 233 is provided with a positioning notch 2331 and a ninth connecting hole 2332, the positioning convex 131 is embedded in the positioning notch 2331 to realize positioning and cooperation, and the eighth connecting hole 132 is aligned with the ninth connecting hole 2332 and then connected through a sixth connecting piece 234, so as to fix the baffle 233 to the support 13.

[0108] Among them, the eighth connecting hole 132 can be a screw hole, the ninth connecting hole 2332 is a through hole or a light hole, and the sixth connecting piece 234 is a connecting screw, so that the sixth connecting piece 234 is screwed into the eighth connecting hole 132 after passing through the ninth connecting hole 2332, so that the baffle 233 is fixed to the support 13.

[0109] Compared with the crossbeam 12, the height of the support 13 is higher, and the height of the support 13 is close to the height of the first-form expansion card 23, and the support 13 is provided with positioning grooves spaced along the third direction, and the number of the positioning grooves is determined according to the number of the first-form expansion cards 23 to be installed, and when installed, the first-form expansion card 23 is correspondingly arranged in the positioning groove of the support 13, so as to facilitate the butt joint of the baffle 233 and the corresponding positioning structure and connecting hole position of the support 13.

[0110] In this way, when the first-form expansion card 23 is assembled, on the one hand, the first-form expansion card 23 is inserted into the second connector 215 on the substrate 21 through the gold finger, and on the other hand, the two sides of the first-form expansion card 23 along the second direction are respectively fixed and connected to the crossbeam 12 and the support 13, specifically, one side of the first-form expansion card 23 along the second direction is fixed and connected to the crossbeam 12 through the second fixing frame 231, and the other side of the first-form expansion card 23 along the second direction is fixed and connected to the support 13 through the baffle 233.

[0111] It can be understood that the gold finger of the first form expansion card 23 is inserted into the second connector 215 (usually a PCIe slot) on the motherboard 21 through its gold finger (a row of metal contact points). The gold finger is designed to match the contact points in the slot precisely to ensure electrical connection; the fixed connection of the first form expansion card 23: To ensure that the first form expansion card 23 is fixed in the case 10 to prevent the first form expansion card 23 from loosening due to vibration during transportation or use, the first form expansion card 23 is fixed and connected to the crossbeam 12 along one side of the second direction through the second fixing bracket 13, where the crossbeam 12 is a support structure inside the case 10 for fixing and supporting the network card 22 and the first form expansion card 23, at the same time, the first form expansion card 23 is fixed and connected to the bracket 13 along the other side of the second direction through the stop sheet 233, the stop sheet 233 can be designed as a metal or plastic component that fits the height and width of the first form expansion card 23, used to fix the edge of the first form expansion card 23 on the bracket 13 of the case 10 to prevent it from falling off.

[0112] When assembling, first fix the second fixing bracket 231 and the stop sheet 233 on both sides of the first form expansion card 23 respectively, then align the gold finger at the bottom of the first form expansion card 23 with the slot on the motherboard 21, then gently press down the first form expansion card 23 until the gold finger is fully inserted into the slot, then fix and connect the second fixing bracket 231 and the stop sheet 233 to the crossbeam 12 and the bracket 13 respectively to fix the first form expansion card 23.

[0113] After installation is complete, check whether the first form expansion card 23 is firmly fixed and perform a boot test to ensure that the first form expansion card 23 is correctly recognized by the system and functions normally.

[0114] This installation method ensures the stability and safety of the first form expansion card 23 in the case 10 and correctly connects with the interface on the motherboard 21, preventing poor contact or damage due to physical impact or vibration during daily use, and at the same time, by using the second fixing bracket 231 and the stop sheet 233, the case 10 design can be compatible with expansion cards of various sizes and shapes, improving the compatibility and flexibility of the case 10.

[0115] Please refer to Figure 7 , the motherboard 21 is provided with at least two fixing holes 212 for connecting the fixing member to fix the motherboard 21 to the case 11.

[0116] Of course, according to actual needs, the fixing hole 212 can be a gourd hole, the fixing member can be a dowel, the number of the fixing hole 212 and the fixing member is two, and the two fixing holes 212 are arranged on the base plate 21, and the base plate 21 and the bottom plate of the box body 11 are connected through the two fixing members penetrating through the two fixing holes 212 respectively, so as to ensure that the base plate 21 is fixed in the box body 11.

[0117] In order to facilitate carrying the base plate 21 in this state, the base plate 21 is further provided with a pair of hand carrying connecting members 213, which are arranged on the side of the fixing hole 212 away from the network card 22. It should be noted that the hand carrying connecting member 213 can be a hand carrying screw, and the positions of the pair of hand carrying screws should be arranged at the middle position of the base plate 21, so as to ensure the stability of the base plate 21 when carrying the base plate 21.

[0118] In addition, the base plate 21 is further provided with a second connector 215, and the first mode expansion card 23 is inserted into the second connector 215. The second connector 215 is usually a PCIe slot.

[0119] Please refer to Figure 9 and Figure 10 , the expansion card is a second mode expansion card 24 (OAM mode GPU card), and the base plate 21 is provided with a third connector 216, and the second mode expansion card 24 is inserted into the third connector 216.

[0120] In order to facilitate the connection of the base plate 21 with the second mode expansion card 24 and the box body 11, the box body 11 is provided with a stud, and the base plate 21 is further provided with a through hole, which is aligned with the stud and connected through a fastener 217. The fastener 217 can be a non-loose screw, that is, the non-loose screw penetrates through the through hole of the base plate 21 and is screwed on the stud of the box body 11, so that the base plate 21 is firmly fixed on the box body 11.

[0121] Please refer to Figure 12 , in order to facilitate carrying the base plate 21 in this state, the base plate 21 is further provided with a pair of handles 218 located on both sides of the second mode expansion card 24.

[0122] The handle 218 is a U-shaped handle, and the two handles 218 are detachably connected to the upper surface of the base plate 21 through screws. When it is necessary to carry the base plate 21 with the second mode expansion card 24 inserted, the two handles 218 can be installed on the base plate 21, and the base plate 21 with the second mode expansion card 24 inserted can be carried through the two handles 218, so as to facilitate the installation of the base plate 21 into the box body 11.

[0123] In some embodiments, the substrate 21 is provided with a first connector 214, and the network card 22 is plugged into the first connector 214. For example, two first connectors 214 can be arranged on the substrate 21 near the two side edges of the end close to the front window 14, so that four network cards 22 can be assembled on the substrate 21 for network connection.

[0124] For reference Figure 11 The case 10 further includes a front window 14 detachably connected to the case body 11. The front window 14 is rotationally connected with a pressing plate 141. The pressing plate 141 is used to rotate relative to the front window 14 and then be fixed to the front window 14 to press the network card 22 and prevent the network card 22 from being separated from the first connector 214.

[0125] It should be noted that one pressing plate 141 can cover at least two network cards 22. For the substrate 21 assembled with four network cards 22, two pressing plates 141 can be assembled on the front window 14, and one of the pressing plates 141 corresponds to pressing two network cards 22.

[0126] The pressing plate 141 is rotationally connected to the front window 14 through a rotation shaft in a third direction. In this way, the pressing plate 141 can rotate relative to the front window 14 along the axis of the third direction. When the pressing plate 141 is flipped upward to the outside of the front window 14, the installation space of the corresponding network card 22 can be released, and the network card 22 can be inserted into the corresponding first connector 214. After the network card 22 is plugged in, the pressing plate 141 is rotated again to face the front window 14. After the pressing plate 141 is rotated in place, the pressing plate 141 is fixedly connected to the front window 14 by screws. In this way, the pressing effect of the pressing plate 141 on the network card 22 can be achieved.

[0127] In addition, the detachable front window 14 is compatible with the installation of the substrate 21 in the case 10 in both PCIe form GPU card and OAM form GPU card scenarios.

[0128] In this way, when the network card 22 is assembled, the network card 22 is plugged into the first connector 214 on the substrate 21 through the gold finger. At the same time, the network card 22 is fixedly connected to the cross beam 12 through the first fixing frame 221 on the side close to the expansion card. In addition, the network card 22 inserted into the first connector 214 is pressed by the pressing plate 141 to ensure the stability of the installation of the network card 22.

[0129] It can be understood that, similarly, the network card 22 is inserted into the first connector 214 (usually a PCIe slot) on the motherboard 21 through its gold finger (a row of metal contact points), which is designed to match the contact points in the slot precisely to ensure electrical connection. Through the fixation of the first fixing bracket 221 and the pressing plate 141, it can be ensured that the network card 22 is fixed in the case 10 to prevent it from loosening due to vibration during transportation or use. Specifically, the side of the network card 22 close to the expansion card is fixedly connected to the crossbeam 12 through the first fixing bracket 221, which serves as a support structure inside the case 10 for fixing and supporting the network card 22 and the expansion card. In order to further ensure the stability of the network card 22, the network card 22 inserted into the first connector 214 is pressed by the pressing plate 141, which is usually a metal or plastic component that covers the network card 22 and is fixed to the case 10 by screws or buckles to increase additional pressure and prevent the network card 22 from loosening due to vibration.

[0130] When installing the network card 22, the first fixing bracket 221 can be fixedly connected to the network card 22 first, then the gold finger of the network card 22 is aligned with the slot of the first connector 214, after which the network card 22 is gently pressed until the gold finger is fully inserted into the slot. Then, the network card 22 is pressed by the pressing plate 141, and the pressing plate 141 is fixed to the front window 14. Finally, the first fixing bracket 221 is fixedly connected to the crossbeam 12.

[0131] After installation, it should be checked whether the network card 22 is firmly fixed and tested to ensure that the network card 22 is correctly recognized by the system and functions normally.

[0132] This installation method ensures the stability and safety of the network card 22 in the case 10, preventing poor contact or damage due to physical impact or vibration in daily use. At the same time, by using the first fixing bracket 221 and the pressing plate 141, the case 10 design can be compatible with network cards 22 of various sizes and shapes, improving the compatibility and flexibility of the case 10.

[0133] The above process ensures that the network card 22 can be stably installed in the case 10 and correctly connected to the interface on the motherboard 21. In this way, it can be ensured that the network card 22 can work reliably in various use environments.

[0134] In addition, in some cases, the network card 22 also needs additional cooling measures such as heat sinks or fans to prevent overheating, and the installation of the network card 22 should also consider electromagnetic interference shielding to ensure the stability of the network connection.

[0135] Specifically, a metal shield with good conductivity can be set between the network card 22 and the expansion card, and the metal shield can be grounded to reduce the electromagnetic interference of the expansion card on the network card 22 when it is working. The higher the magnetic permeability and the thicker the shield, the smaller the magnetic resistance and the better the magnetic field shielding effect. When the effect of single-layer shielding does not meet the requirements, multi-layer shielding can be used. At the same time, the grounding design of the shield is the key to suppressing electromagnetic interference.

[0136] In some embodiments, a prompt component can be provided to indicate that the network card 22 is in place. For example, a first elastic clip is provided on the network card 22, and a second elastic clip is provided on the substrate 21 to cooperate with the first elastic clip. When the network card 22 is installed in place, the first elastic clip and the second elastic clip are engaged and collide with each other to emit a click sound, thereby reminding the staff that the network card 22 has been installed in place.

[0137] Of course, an indicator light indicating that the network card 22 is plugged in place may also be provided on the base plate 21. Once the network card 22 is plugged in place, the indicator light may light up to remind the staff that the network card 22 has been installed in place.

[0138] In some embodiments, the crossbeam 12 is provided with a first heat dissipation air hole 1215, the front window 14 is provided with a second heat dissipation air hole 142, and a guide air duct is provided between the front window 14 and the crossbeam 12. The two ends of the guide air duct are respectively connected to the first heat dissipation air hole 1215 and the second heat dissipation air hole 142, so that the heat generated by the expansion card flows out of the chassis 10 through the first heat dissipation air hole 1215, the guide air duct and the second heat dissipation air hole 142 in sequence.

[0139] In this way, first heat dissipation holes 1215 are provided on the crossbeam 12, which allow air circulation and help to extract hot air from the inside of the chassis 10. Second heat dissipation holes 142 are provided on the front window 14, which allow external cold air to enter the inside of the chassis 10 to replace the extracted hot air. The guide air duct is a channel connecting the first heat dissipation holes 1215 and the second heat dissipation holes 142. The guide air duct guides the air flow to ensure that the hot air can be effectively discharged from the inside of the chassis 10.

[0140] With this arrangement, the heat dissipation performance is improved by optimizing the air flow path inside the chassis 10, ensuring that the hardware inside the chassis 10 can operate stably at a suitable temperature.

[0141] In some embodiments, the inner wall of the box body 11 is provided with a first limiting structure, and the substrate 21 is provided with a second limiting structure. When the substrate 21 is installed into the box body 11 along the first direction, the first limiting structure contacts and abuts against the second limiting structure to limit the displacement of the substrate 21 along the second direction.

[0142] For example, the first limiting structure may be a raised inner wall, and the corresponding second limiting structure may be an avoidance space.

[0152] It should be noted that the insertion of the network card 22 into the substrate 21 refers to the insertion of the network card 22 into the first connector 214 (usually a PCIe slot) on the substrate 21 through a row of metal contact points; the fixation of the network card 22 to the cross beam 12 refers to the fixation of the first fixing frame 221 connected to the network card 22 to the cross beam 12 through screws, so that the network card 22 is fixed to the cross beam 12 through the first fixing frame 221 on the basis of the insertion of the network card 22 into the substrate 21, to ensure the stable installation of the network card 22 to the substrate 21.

[0153] More specifically, the steps of assembling the network card 22 include: first, fixing the first fixing frame 221 on the side of the network card 22 close to the crossbeam 12, then turning the pressing plate 141 on the front window 14 outward, then inserting the network card 22 fixed with the first fixing frame 221 into the base plate 21, and turning the pressing plate 141 inward and fixing it to the front window 14, and finally fixing the first fixing frame 221 to the crossbeam 12 by screw connection.

[0155] In S5, when assembling the second form expansion card 24, the second form expansion card 24 is inserted into the base plate 21, and the second form expansion card 24 is locked to the base plate 21 by long screws.

[0158] Secondly, by arranging the crossbeam 12 inside the cabinet 11, the network card 22 and the first form expansion card 23 can be further fixed on the basis of being inserted into the corresponding connectors on the base plate 21, which ensures the installation firmness of the network card 22 and the first form expansion card 23 in the cabinet 11, and prevents the network card 22 and the first form expansion card 23 from being displaced or damaged due to vibration or accidental collision during transportation or operation;
