Description

Technical Field

[0001] The present application relates to the field of server technology, and in particular to a circuit board module and a server. Background Art

[0002] A server is a device used to provide data processing. The data in the server is stored in a memory, and the memory is connected to the circuit board to facilitate data retrieval.

[0003] In the related art, a circuit board is placed in a server chassis, and a connection terminal is provided on the circuit board. The memory is connected to the circuit board via the connection terminal. The circuit board and the chassis are connected with screws. However, this connection method makes the installation and maintenance of the circuit board inconvenient. Summary of the Invention

[0004] The present application provides a circuit board module and a server to at least solve the problem of inconvenience in installation and maintenance of circuit boards in the related art.

[0005] In a first aspect, the present application provides a circuit board module for use in a server. The server includes a chassis, and the circuit board module is disposed within the chassis. The circuit board module includes:

[0006] circuit board.

[0007] The first connecting member is connected to one end of the circuit board in a snap-fit manner along a first direction, and the side of the first connecting member facing away from the circuit board is used for snap-fitting with the inner wall of the chassis.

[0008] The second connecting member is connected to the other end of the circuit board in a snap-fit manner along the first direction, and the side of the second connecting member facing away from the circuit board is used for snap-fitting with the inner wall of the chassis.

[0009] The first direction intersects with the thickness direction of the circuit board.

[0010] The circuit board module provided in the present application fixes and limits the circuit board through the first connecting member and the second connecting member, preventing the circuit board from moving along the first direction, so as to facilitate the connection between the circuit board and the hard disk, and also prevent the problem of abnormal electrical connection between the hard disk and the circuit board caused by the position movement of the circuit board, so as to stabilize the operation of the server and improve the performance of the server. The first connecting member and the second connecting member are both connected to the circuit board in a snap-on manner. In this way, the number of screws can be reduced, so as to facilitate the installation and maintenance of the circuit board, thereby improving the installation efficiency and maintenance efficiency of the circuit board. As the number of screws is reduced, the available area of the circuit board increases, and the size of the circuit board can be reduced. On the basis of meeting the performance of the server, the space occupied by the circuit board is reduced, which helps to miniaturize the server, and thus can also reduce the production cost of the server.

[0011] In a second aspect, the present application further provides a server, including: a chassis and the circuit board module provided in the first aspect. The chassis has a receiving cavity, and the circuit board module is disposed in the receiving cavity.

[0012] Since the server provided by the present application includes the circuit board module in any of the embodiments in the foregoing first aspect, the installation efficiency and maintenance efficiency of the server, as well as the working stability and performance of the server, can be improved.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

[0044] It should be noted that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. The terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

For example, "parallel" includes absolute parallel and approximate parallel, and the acceptable deviation range of approximate parallel can be, for example, within 5° deviation; "perpendicular" includes absolute perpendicular and approximate perpendicular, and the acceptable deviation range of approximate perpendicular can also be, for example, within 5° deviation.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0045] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0046] In the first aspect, in combination with Figure 1 and Figure 2 , an embodiment of the present application provides a circuit board module 100, which is applied to a server. It can be understood that the server includes a chassis 200, and the circuit board module 100 is disposed in the chassis 200 to form a supporting and connecting function for the circuit board module 100 through the chassis 200. The chassis 200 can also be used as a protective structural member for the circuit board module 100 to protect the circuit board module 100, preventing dust, water vapor, etc. in the external environmental substances of the chassis 200 from entering the chassis 200, affecting the heat dissipation performance of the circuit board 110, and the service performance of the server, thereby improving the data processing performance of the server and the working stability of the server.

[0047] In some embodiments, the circuit board module 100 includes a circuit board 110, which can be used for electrical connection with electrical components. For example, the circuit board 110 can be provided with a central processing unit (CPU), a memory, etc. to meet the data processing requirements of the server. Among them, the memory can be a hard disk 300, etc., and the embodiments of the present application do not make specific requirements for this.

[0048] Among them, when the hard disk 300 is connected to the circuit board 110, different connection terminals 117 can be provided on the circuit board 110, and the hard disk 300 is connected to the circuit board 110 through the connection terminals 117, so as to facilitate a stable electrical connection between the circuit board 110 and the hard disk 300, making the data processing and signal interaction of the server more stable.

[0049] Exemplarily, different types of hard disks 300 have corresponding different interfaces. Common interfaces of the hard disk 300 include serial interfaces, such as SAS interface (Serial Attached SCSI), SATA interface (Serial ATA), NVMe interface (NVM Express), etc. The structure of the connection terminal 117 in the embodiments of the present application matches the interface of the hard disk 300, so that the hard disk 300 can be directly plugged and matched with the connection terminal 117 through the interface.

[0050] In the process of specific implementation, the assembly force between different interfaces of the hard disk 300 and the connection terminal 117 is also different. Exemplarily, the assembly force between the hard disk 300 with SAS interface and SATA interface and the connection terminal 117 is usually 25N, and the assembly force between the hard disk 300 with NVMe interface and the connection terminal 117 is usually 59N. Due to the different assembly forces between the hard disk 300 and the circuit board 110, abnormal situations such as an increase in the assembly force and deformation of the circuit board 110 may occur, and the biting distance between the interface of the hard disk 300 and the connection terminal 117 is insufficient, resulting in abnormal electrical connection between the hard disk 300 and the circuit board 110, and the rate of data retrieval and storage of the hard disk 300 by the server is reduced, affecting the use performance and stability of the server.

[0051] In addition, inside the chassis 200, the circuit board 110 and the inner side wall of the chassis 200 are often connected by screws. In some embodiments, the number of screws can be increased, and multiple fixing points are provided between the circuit board 110 and the side wall of the chassis 200 through multiple screws, thereby improving the connection stability between the circuit board 110 and the chassis 200. However, such a connection method will reduce the installation efficiency and maintenance efficiency of the circuit board 110.

[0052] It can be understood that as the number of screws increases, the number of screw holes on the circuit board 110 increases, which leads to changes in the wiring layout of the circuit board 110 and a reduction in the available area for the wiring of the circuit board 110. To meet the server's data processing requirements, it is necessary to increase the wiring area of the circuit board 110 to make the wiring layout reasonable, reduce the mutual interference between signals, improve the reliability and stability of the server's signal processing, and help improve the heat dissipation efficiency of the circuit board 110 so that the working temperature of the circuit board 110 is maintained within a stable range, thereby improving the usage performance of the server. However, as the area of the circuit board 110 increases, it is not conducive to the miniaturization of the server. When the area of the circuit board 110 increases, the deformation amount of the circuit board 110 also changes, which easily leads to a deterioration in the performance of the server.

[0053] To solve the above defects, refer to Figures 1 to 6 , the circuit board module 100 in the embodiment of the present application further includes a first connecting member 120 and a second connecting member 130. The first connecting member 120 and the second connecting member 130 are arranged at opposite ends of the circuit board 110 along the first direction (X) to fix and limit the circuit board 110 through the first connecting member 120 and the second connecting member 130, prevent the circuit board 110 from moving along the first direction (X), facilitate the connection between the circuit board 110 and the hard disk 300, and also prevent the problem of abnormal electrical connection between the hard disk 300 and the circuit board 110 caused by the position movement of the circuit board 110, so that the server runs stably and the usage performance of the server is improved.

[0054] In an alternative embodiment, the first connecting member 120 and the circuit board 110 are connected in a snap-fit manner. In this way, the first connecting member 120 and the circuit board 110 are connected in a snap-fit manner, which can reduce the number of screws, facilitate the installation and maintenance of the circuit board 110, and thus improve the installation efficiency and maintenance efficiency of the circuit board 110. As the number of screws decreases, the available area of the circuit board 110 increases, the size of the circuit board 110 can be reduced, and on the basis of meeting the server's performance, the space occupation ratio of the circuit board 110 can be reduced, which helps the miniaturization of the server, and in this way, the production cost of the server can also be reduced.

[0055] In the embodiment of the present application, along the first direction (X), the side of the first connecting member 120 facing away from the circuit board 110 is connected to the box wall of the chassis 200 in a snap-fit manner, which facilitates the installation and disassembly of the circuit board module 100 and the chassis 200, reduces the installation difficulty and maintenance difficulty of the server, and improves the installation efficiency and maintenance efficiency.

[0056] Optionally, the second connector 130 and the circuit board 110 are connected in a snap-fit manner. In this way, the second connector 130 and the circuit board 110 are connected by a snap-fit manner, which can reduce the number of screws, facilitating the installation and maintenance of the circuit board 110, thereby improving the installation efficiency and maintenance efficiency of the circuit board 110. With the reduction of the number of screws, the available area of the circuit board 110 increases, the size of the circuit board 110 can be reduced, and on the basis of meeting the performance of the server, the space occupation ratio of the circuit board 110 is reduced, which helps to miniaturize the server, and thus the production cost of the server can also be reduced.

[0057] In the embodiment of the present application, along the first direction (X), the side of the second connector 130 facing away from the circuit board 110 and the wall of the chassis 200 are connected in a snap-fit manner, facilitating the installation and disassembly of the circuit board module 100 and the chassis 200, reducing the installation difficulty and maintenance difficulty of the server, and improving the installation efficiency and maintenance efficiency.

[0058] It can be understood that the first connector 120 and the second connector 130 are connected to both ends of the circuit board 110 along the first direction (X). By such a setting method, the stability of the circuit board module 100 is improved, the deformation of the circuit board 110 can be reduced, and the electrical connection between the hard disk 300 and the circuit board 110 is stable, thereby improving the working stability of the server.

[0059] It should be noted that the first direction (X) in the embodiment of the present application intersects with the thickness direction (Y) of the circuit board 110. That is to say, the first direction (X) can be the length direction of the circuit board 110 or the width direction of the circuit board 110. Among them, the embodiment of the present application takes the first direction (X) along the length direction of the circuit board 110 as an example for illustration. Refer to Figure 1 Define the first direction (X) as X and the thickness direction (Y) of the circuit board as Y.

[0060] In combination with the foregoing embodiments, both the first connector 120 and the second connector 130 are connected to the circuit board 110 in a snap-fit manner. Among them, there are various ways to achieve snap-fit. As an alternative embodiment, at least one of the first connector 120 and the second connector 130 has a card slot. In the first connector 120, the first connector 120 is connected to the circuit board 110 through the card slot; in the second connector 130, the second connector 130 is connected to the circuit board 110 through the card slot. In the embodiment of the present application, the first connector 120 and / or the second connector 130 are connected to the circuit board 110 through corresponding card slots. In this way, the movement of the circuit board 110 is restricted by the setting of the card slot, improving the structural stability of the circuit board module 100. Moreover, the structure of the card slot is simple, facilitating the connection between the first connector 120 and / or the second connector 130 and the circuit board 110, making the installation and maintenance of the circuit board module 100 more convenient, and facilitating the production of the first connector 120 and / or the second connector 130, improving the production efficiency of the circuit board module 100 and the server.

[0061] Combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , as an alternative embodiment, the first connector 120 has a first card slot 121, and the first card slot 121 extends along the first direction (X). The first connector 120 and the circuit board 110 are connected through the first card slot 121.

[0062] Exemplarily, the first card slot 121 extends along the first direction (X), and the slot opening of the first card slot 121 faces the circuit board 110. In this way, the circuit board 110 can enter the first card slot 121 relative to the first connector 120 along the first direction (X). When maintaining the circuit board 110, it is only necessary to move the circuit board 110 along the first direction (X) towards the side where the second connector 130 is located until it is disconnected from the first card slot 121. In this way, through the setting of the first card slot 121, screws are no longer used for fixing during the installation of the circuit board 110, facilitating the installation and disassembly of the circuit board 110, thereby improving the installation and disassembly efficiency of the circuit board module 100 and the server, and facilitating the maintenance of the circuit board module 100 and the server. In addition, the number of screws is reduced, which can increase the available area for wiring on the circuit board 110, reduce the structural size of the circuit board 110, reduce the space occupancy ratio of the circuit board 110, and thus contribute to the miniaturization and light weight of the server.

[0063] It should be noted that in the embodiments of the present application, the structures of the first card slot 121 and the end of the circuit board 110 are adapted to each other. That is to say, along the first direction (X), the inner wall of the first card slot 121 and the end face of the circuit board 110 are structurally matched, and along the second direction (Z), the extension length of the first card slot 121 is the same as the extension length of the end of the circuit board 110 that cooperates therewith. In this way, through the structural setting of the first card slot 121, the circuit board 110 is prevented from moving along the first direction (X), thereby reducing the probability of abnormal electrical connection between the circuit board 110 and the hard disk 300 and improving the operation reliability of the server.

[0064] Combined with Figure 1 、 Figure 2 、 Figure 4 and Figure 6 , in some embodiments, the second connecting member 130 has a second card slot 131, and the second card slot 131 extends along the first direction (X). The second connecting member 130 and the circuit board 110 are connected through the second card slot 131.

[0065] It should be noted that the structures and functions of the second card slot 131 and the first card slot 121 are similar, and the structure of the second card slot 131 will not be described in detail in this part.

[0066] It can be understood that the first connecting member 120 is connected to the circuit board 110 through the first card slot 121, and the second connecting member 130 is connected to the circuit board 110 through the second card slot 131. The two ends of the circuit board 110 are respectively located in the corresponding first card slot 121 and the corresponding second card slot 131. In this way, the movement of the circuit board 110 along the second direction (Z) can also be restricted by the first card slot 121 and the second card slot 131, as well as the rotation of the circuit board 110 around the axis parallel to the first direction (X). In this way, when the hard disk 300 is connected to the circuit board 110, the circuit board 110 is prevented from being deformed and flipped due to the force exerted by the hard disk 300. Therefore, in the embodiments of the present application, through such first connecting member 120 and second connecting member 130, the structural stability of the circuit board module 100 is improved, so that the electrical connection between the hard disk 300 and the circuit board 110 is stable, thereby improving the operation stability of the server.

[0067] It should be noted that in the embodiments of the present application, the first direction (X), the second direction (Z) and the thickness direction (Y) of the circuit board 110 are perpendicular to each other. Among them, the first direction (X) is along the length direction or the width direction of the circuit board 110, and the second direction (Z) is along the width direction or the length direction of the circuit board 110. Combining the foregoing content, in the embodiments of the present application, the first direction (X) is along the length direction of the circuit board 110, and the second direction (Z) is along the width direction of the circuit board 110 as an example to illustrate the content of the present application. Refer to Figure 1 , define the second direction (Z) as Z.

[0068] Furthermore, in an alternative embodiment of the present application, only the first connecting member 120 may have the first card slot 121; or, only the second connecting member 130 may have the second card slot 131; or, the first connecting member 120 has the first card slot 121 and the second connecting member 130 has the second card slot 131.

[0069] In some embodiments, at least one of the first card slot 121 and the second card slot 131 has a stop portion; the stop portion of the first card slot 121 stops at the end of the circuit board 110; the stop portion of the second card slot 131 stops at the end of the circuit board (110).

[0070] Exemplarily, the stop portion may be a convex structure, a concave groove structure, etc., and the embodiments of the present application do not make requirements in this regard.

[0071] Optionally, the first card slot 121 has a first stop portion 1211. Along the first direction (X), the first stop portion 1211 is located on the side of the first card slot 121 facing the circuit board 110 and stops at the end of the circuit board 110.

[0072] In some embodiments, referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , along the thickness direction (Y) of the circuit board 110, the first stop portion 1211 may protrude relative to the groove wall of the first card slot 121. That is to say, the first stop portion 1211 may be a convex structure, a boss structure, a step structure, etc., and the embodiments of the present application do not make requirements in this regard. Along the first direction (X), the shape of the first stop portion 1211 matches the shape of the end of the circuit board 110. In this way, through the stop cooperation between the first stop portion 1211 and the circuit board 110, the movement of the circuit board 110 along the first direction (X) is better restricted, so that the circuit board module 100 remains stable relative to the chassis 200, thereby improving the operation stability and reliability of the server. It can be understood that through the setting of the first stop portion 1211, the first stop portion 1211 and the circuit board 110 form a stop connection relationship in a surface-to-surface cooperation manner, which not only restricts the movement of the circuit board 110 but also facilitates the installation of the circuit board 110 and the first connecting member 120, thereby improving the installation efficiency and maintenance efficiency of the circuit board module 100 and the server.

[0073] It should be noted that along the second direction (Z), the extension length of the first stop portion 1211 may be equal to or less than the extension length of the circuit board 110, and the embodiments of the present application do not limit this.

[0074] Optionally, referring to Figure 1 、 Figure 2 、 Figure 4 and Figure 6, the second card slot 131 has a second stop portion 1311. Along the first direction (X), the second stop portion 1311 is located on the side of the second card slot 131 facing the circuit board 110 and stops at the end of the circuit board 110.

[0075] It should be noted that the structure and function of the second stop portion 1311 in the embodiments of the present application are similar to those of the first stop portion 1211, and this part will not be elaborated here.

[0076] The structure of the circuit board 110 is diverse. Refer to Figure 1 , Figure 2 and Figure 8 , in an alternative embodiment of the present application, the circuit board 110 has a notch 111. Along the first direction (X), the notch 111 is located at the end of the circuit board 110 facing the second card slot 131. In order to improve the connection stability between the circuit board 110 and the second connector 130 through the second card slot 131, the shapes of the notch 111 and the second stop portion 1311 in this embodiment match each other, and the second stop portion 1311 and the notch 111 are cooperatively connected to stop the circuit board 110.

[0077] Along the second direction (Z), the extension length of the second stop portion 1311 can be less than or equal to the extension length of the notch 111, so that the circuit board 110 and the second stop portion 1311 are cooperatively connected to improve the assembly efficiency of the circuit board module 100. At the same time, the cooperation between the second stop portion 1311 and the notch 111 forms a positioning effect on the installation of the circuit board 110, preventing the situation where the circuit board 110 is deformed and damaged due to the mating deviation between the circuit board 110 and the second connector 130, and further improving the assembly efficiency of the circuit board module 100.

[0078] In some embodiments, along the thickness direction (Y) of the circuit board 110, the extension length of the second stop portion 1311 can be less than the extension length of the notch 111 or greater than the extension length of the notch 111.

[0079] Among them, when along the thickness direction (Y) of the circuit board 110, the extension length of the second stop portion 1311 is less than the extension length of the notch 111, the second stop portion 1311 still forms a stopping and positioning effect on the circuit board 110 through the cooperation with the notch 111, but the circuit board 110 is prone to shaking or misinsertion, and even the situation of deformation of the circuit board 110 may occur.

[0080] When the extension length of the second stop portion 1311 is greater than that of the notch 111 in the thickness direction (Y) of the circuit board 110, the second stop portion 1311 will cause an increase in the groove-shaped space of the second card slot 131, resulting in the circuit board 110 being prone to shaking and deformation caused by uneven stress on the circuit board 110. Moreover, the increase in the groove-shaped space of the second card slot 131 leads to an increase in the structural size of the second connecting member 130 and an increase in the space occupation ratio of the second connecting member 130, which is not conducive to reducing the space occupation ratio of the circuit board module 100 and the server.

[0081] Therefore, in the embodiment of the present application, in the thickness direction (Y) of the circuit board 110, the extension length of the second stop portion 1311 is equal to that of the notch 111, so as to cooperate with each other through the second stop portion 1311 and the notch 111 to make the structure of the circuit board module 100 stable and avoid the reduction of the performance of the server caused by the deformation of the circuit board 110.

[0082] Exemplarily, the sizes of the circuit boards 110 are different, and both ends of the circuit board 110 in the first direction (X) have a plurality of latching segments, and the plurality of latching segments are arranged at intervals in the second direction (Z). The first card slot 121 of the first connecting member 120 and the second card slot 131 of the second connecting member 130 respectively correspond to the latching segments of the circuit board 110 one by one. In this way, through such a setting, the circuit board 110 is respectively latched with the first connecting member 120 and the second connecting member 130 at multiple positions, improving the structural stability of the circuit board module 100.

[0083] In some embodiments, the circuit board 110 is provided with a plurality of latching portions, the first connecting member 120 is connected to the circuit board 110 through at least one latching portion, and the second connecting member 130 is connected to the circuit board 110 through at least one latching portion.

[0084] Exemplarily, the latching portion can be a groove-shaped structure, a step structure, etc., and the embodiment of the present application does not make specific requirements for this. Among them, the latching portion is adapted to the structure on the circuit board and realizes stable latching.

[0085] Combined Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , in some embodiments, the circuit board 110 is provided with a first latching portion, the first connecting member 120 is provided with a first buckle 122, and the first connecting member 120 and the circuit board 110 are connected through the first buckle 122 and the first latching portion. In this way, through the latching cooperation between the first buckle 122 and the first latching portion, the movement of the circuit board 110 in the first direction (X) is further restricted, making the structure of the circuit board module 100 stable.

[0086] Exemplarily, the first buckle 122 can be an elastic buckle.

[0087] Combined with Figure 1 、 Figure 2 、 Figure 4 and Figure 6 In some embodiments, a second latching portion is provided on the circuit board 110, and the second connecting member 130 is provided with a second buckle 132. The second connecting member 130 and the circuit board 110 are latched through the second buckle 132 and the second latching portion.

[0088] It should be noted that the structure and function of the second latching portion in the embodiments of the present application are the same as those of the first latching portion, and the structure and function of the second buckle 132 and the first buckle 122 are the same, and will not be elaborated herein.

[0089] Exemplarily, the second buckle 132 can be an elastic buckle.

[0090] It should be noted that in the embodiments of the present application, only the first connecting member 120 and the circuit board 110 may be connected through the first buckle 122 and the first latching portion, or only the second connecting member 130 and the circuit board 110 may be connected through the second buckle 132 and the second latching portion. Or, when the first connecting member 120 and the circuit board 110 are connected through the first buckle 122 and the first latching portion, the second connecting member 130 and the circuit board 110 are connected through the second buckle 132 and the second latching portion.

[0091] When the first connecting member 120 and the circuit board 110 are connected through the first buckle 122 and the first latching portion, the second connecting member 130 and the circuit board 110 are connected through the second buckle 132 and the second latching portion. The first buckle 122 and the second buckle 132 form a tension on the circuit board 110 along the first direction (X), and the load distribution of the circuit board 110 along the first direction (X) is uniform. Thus, the circuit board 110 is not easily deformed, the electrical connection between the circuit board 110 and the hard disk 300 is stable, which is beneficial to improving the reliability and stability of the server, as well as the performance of the server.

[0092] In addition, in the embodiments of the present application, by means of the first buckle 122 and the second buckle 132 being respectively latched with the first latching portion and the second latching portion of the circuit board 110, the number of screws for fixing the circuit board 110 is reduced, which facilitates the installation and maintenance of the circuit board module 100, reduces the cost and weight of the server, and is beneficial to realizing the lightweight of the server.

[0093] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 7, in some embodiments, the first engaging portion includes a first engaging hole 112. Along the thickness direction (Y) of the circuit board 110, the first engaging hole 112 penetrates through the circuit board 110; along the first direction (X), the first engaging buckle 122 is engaged with the hole wall of the first engaging hole 112. In this way, through the cooperation between the first engaging buckle 122 and the hole wall of the first engaging hole 112, the connection and disassembly of the circuit board 110 and the first connecting member 120 are facilitated, and the installation efficiency and maintenance efficiency of the circuit board module 100 are improved. Furthermore, through the mutual cooperation between the first engaging buckle 122 and the first engaging hole 112, the movement of the circuit board 110 along the first direction (X) is restricted, the movement of the circuit board 110 along the thickness direction (Y) of the circuit board 110 is restricted, and the rotation of the circuit board 110 around the axis parallel to the first direction (X) is restricted, making the structure of the circuit board module 100 stable and preventing abnormal electrical connection after the hard disk 300 and the circuit board 110 are connected, thereby ensuring the stable and reliable operation of the server. In addition, on the basis of meeting the requirements of the wiring layout, through the setting of the first engaging hole 112, the material cost and weight of the circuit board 110 are reduced, and the cost and weight of the server are reduced.

[0094] See Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 , in some embodiments, the second engaging portion includes a second engaging hole 113. Along the thickness direction (Y) of the circuit board 110, the second engaging hole 113 penetrates through the circuit board 110; along the first direction (X), the second engaging buckle 132 is engaged with the hole wall of the second engaging hole 113.

[0095] It should be noted that the structure and function of the second engaging hole 113 in the embodiments of the present application are the same as those of the first engaging hole 112, and the structure and function of the second engaging buckle 132 are the same as those of the first engaging buckle 122, and will not be elaborated herein.

[0096] Optionally, see Figure 9 , Figure 10 , Figure 12 , in some embodiments, the first engaging portion includes a first protruding extension 114. Along the second direction (Z), the first protruding extension 114 protrudes from one side edge of the circuit board 110; along the first direction (X), the first engaging buckle 122 is engaged with the side of the first protruding extension 114 away from the first connecting member 120. In this way, through the engaging cooperation between the first engaging portion and the first protruding extension 114, the fixing of the circuit board 110 is realized, the number of screws is reduced, which is convenient for the maintenance of the circuit board 110, and the installation and maintenance of the circuit board module 100 are improved.

[0097] It can be understood that for a circuit board 110 with a relatively small size, if a hole-shaped structure is provided on the circuit board 110 and is clamped with the first buckle 122, the available area for the circuit traces on the circuit board 110 will decrease. Thus, by providing the first protruding extension 114, not only can such problems be solved, but also the installation of the circuit board 110 can be satisfied, avoiding the need to separately provide different first connectors 120 for small-sized circuit boards 110, thereby improving the applicability of the first connector 120.

[0098] It should be noted that along the second direction (Z), the first protruding extension 114 can be located on either side of the opposite sides of the circuit board 110, and the embodiments of the present application do not make any requirements in this regard.

[0099] See Figure 9 、 Figure 11 、 Figure 13 In the embodiments of the present application, the second clamping portion includes a second protruding extension 115. Along the second direction (Z), the second protruding extension 115 protrudes from one side edge of the circuit board 110; along the first direction (X), the second buckle 132 is clamped with the side of the second protruding extension 115 away from the second connector 130.

[0100] It should be noted that the structure and function of the second protruding extension 115 in the embodiments of the present application are the same as those of the first protruding extension 114, and will not be elaborated herein.

[0101] In some embodiments, along the second direction (Z), the first protruding extension 114 and the second protruding extension 115 can be located on different sides of the circuit board 110, or, along the second direction (Z), the first protruding extension 114 and the second protruding extension 115 are located on the same side of the circuit board 110.

[0102] Among them, when the first protruding extension 114 and the second protruding extension 115 are located on the same side of the circuit board 110, along the first direction (X), both ends of the circuit board 110 can, through the settings of the first connector 120 and the second connector 130, make the load distribution of the circuit board 110 uniform, thereby avoiding structural deformation of the circuit board 110 caused by uneven stress, further improving the stability of the electrical connection between the hard disk 300 and the circuit board 110, and making the working performance of the server reliable and stable. Moreover, the structure of the circuit board 110 is relatively regular to reduce the production difficulty of the circuit board 110.

[0103] It should be noted that in the embodiments of the present application, the lengths by which the first protruding extension 114 and the second protruding extension 115 protrude along the second direction (Z) relative to the circuit board 110 only need to satisfy stable connection with the corresponding first buckle 122 and the corresponding second buckle 132, and the embodiments of the present application do not make any requirements in this regard.

[0104] The snap - fit assembly structure of the circuit board module 100 and the chassis 200 will be described below in conjunction with the structures of the first connecting member 120 and the second connecting member 130.

[0105] Combined with Figure 14 、 Figure 15 、 Figure 16 、 Figure 17 、 Figure 18 In some embodiments, along the first direction (X), on the side of the first connecting member 120 facing away from the circuit board 110, a third snap - fitting portion 123 is provided, and the third snap - fitting portion 123 extends along the second direction (Z); on the box wall of the chassis 200 opposite to the first connecting member 120, a fourth snap - fitting portion 210 is provided, and the fourth snap - fitting portion 210 extends along the second direction (Z); the third snap - fitting portion 123 is used to snap - fit with the fourth snap - fitting portion 210.

[0106] Exemplarily, the third snap - fitting portion 123 can be recessed or protruded relative to the surface of the first connecting member 120 facing the box wall of the chassis 200. Correspondingly, the fourth snap - fitting portion 210 can be protruded or recessed relative to the surface of the chassis 200 facing the first connecting member 120. In this way, through the snap - fit cooperation between the third snap - fitting portion 123 and the fourth snap - fitting portion 210, the movement of the circuit board module 100 in the thickness direction (Y) of the circuit board module 100 is restricted, preventing the occurrence of insufficient clearance and distance between the hard disk 300 and the circuit board 110, thereby improving the connection stability between the hard disk 300 and the circuit board 110, and further improving the stability and reliability of the server.

[0107] During implementation, the circuit board module 100 can be installed in the chassis 200 through the relative sliding between the third snap - fitting portion 123 on the first connecting member 120 and the fourth snap - fitting portion 210 on the chassis 200. In this way, through the settings of the third snap - fitting portion 123 and the fourth snap - fitting portion 210, the number of screws used for fixing the circuit board module 100 and the chassis 200 is reduced. Such a fastening method is more convenient, thus facilitating the installation and maintenance of the circuit board module 100.

[0108] In the embodiments of the present application, along the first direction (X), on the side of the second connecting member 130 facing away from the circuit board 110, a fifth snap - fitting portion is provided, and the fifth snap - fitting portion extends along the second direction (Z); on the box wall of the chassis 200 opposite to the second connecting member 130, a sixth snap - fitting portion is provided, and the sixth snap - fitting portion extends along the second direction (Z); the fifth snap - fitting portion is used to snap - fit with the sixth snap - fitting portion.

[0109] It should be noted that the structure and function of the fifth snap - fitting portion in the embodiments of the present application are the same as those of the third snap - fitting portion 123, and the structure and function of the sixth snap - fitting portion are the same as those of the fourth snap - fitting portion 210, and will not be elaborated herein.

[0110] In the embodiment of the present application, the first connecting member 120 and the chassis 200 are connected through the third engaging portion 123 and the fourth engaging portion 210, and the second connecting member 130 and the chassis 200 are connected through the fifth engaging portion and the sixth engaging portion. Thus, through the arrangement of the first connecting member 120 and the second connecting member 130, the movement and deformation of the circuit board 110 in the thickness direction (Y) of the circuit board 110 are jointly restricted, so that the connection between the circuit board 110 and the hard disk 300, and the connection between the circuit board module 100 and the chassis 200 are stable and reliable, thereby ensuring the stable operation and performance of the server.

[0111] Combined with Figure 14 、 Figure 15 、 Figure 16 、 Figure 17 、 Figure 18 ,the third engaging portion 123 includes a first part 1231 and a second part 1232. Along the second direction (Z), the first part 1231 and the second part 1232 are arranged in sequence, and along the thickness direction (Y) of the circuit board 110, the extension length of the first part 1231 is less than that of the second part 1232; the fourth engaging portion 210 and the third engaging portion 123 are in a matching shape.

[0112] It can be understood that along the second direction (Z), through the arrangement of the first part 1231 and the second part 1232 of the third engaging portion 123, a structure with a narrower upper part and a wider lower part is formed. Correspondingly, since the fourth engaging portion 210 is in a matching shape with the third engaging portion 123, the fourth engaging portion 210 also has a structure with a narrower upper part and a wider lower part. Thus, it is convenient for the third engaging portion 123 and the fourth engaging portion 210 to slide along the second direction (Z), making the connection between the circuit board module 100 and the chassis 200 more convenient.

[0113] It can be understood that referring to Figure 16 、 Figure 17 、 Figure 18 ,the narrower first part 1231 of the third engaging portion 123 is engaged with the narrower part of the fourth engaging portion 210, and the wider second part 1232 of the third engaging portion 123 is engaged with the wider part of the fourth engaging portion 210, thereby restricting the movement of the circuit board module 100 in the chassis 200 in the thickness direction (Y) of the circuit board 110, making the connection between the circuit board module 100 and the chassis 200 stable.

[0114] The fifth engaging portion includes a third part and a fourth part. Along the second direction (Z), the third part and the fourth part are arranged in sequence, and along the thickness direction (Y) of the circuit board 110, the extension length of the third part is less than that of the fourth part; the sixth engaging portion and the fifth engaging portion are in a matching shape.

[0115] It should be noted that the structure and function of the fifth clamping portion in the embodiment of the present application are the same as the structure and function of the third clamping portion 123, and the structure and function of the sixth clamping portion are the same as the structure and function of the fourth clamping portion 210, which will not be repeated here.

[0116] It is easy to understand that in this embodiment of the present application, the third engaging portion 123 on the first connector 120 and the fifth engaging portion on the second connector 130 cooperate with the chassis 200 to restrict movement of the circuit board module 100 within the chassis 200 along the thickness direction (Y) of the circuit board 110. To prevent the circuit board module 100 from moving relative to the chassis 200 along the first direction (X), which could cause the circuit board module 100 and the chassis 200 to become disconnected, a third engaging portion 124 is provided on the side of the first connector 120 facing away from the circuit board 110 along the first direction (X). The third engaging portion 124 is located on the side of the third engaging portion 123 facing away from the circuit board 110 along the thickness direction (Y) of the circuit board 110. The third engaging portion 124 is configured to engage with the wall of the chassis 200 along the first direction (X).

[0117] Illustratively, the case wall of the chassis 200 has a protruding structure or a step structure for the third buckle 124 to be engaged with the chassis 200 .

[0118] In some embodiments, the third clip 124 can be an elastic clip, so that the elastic force of the elastic clip can facilitate the installation and removal of the circuit board module 100 and the chassis 200, thereby reducing the maintenance difficulty of the server and improving the maintenance efficiency.

[0119] In the embodiment of the present application, a fourth clip is provided on the side of the second connecting member 130 facing away from the circuit board 110 along the first direction (X); along the thickness direction (Y) of the circuit board 110, the fourth clip is located on the side of the fifth clip facing away from the circuit board 110; the fourth clip is used to clip with the box wall of the chassis 200 along the first direction (X).

[0120] It should be noted that the connection structure and function between the fourth clip and the wall of the chassis 200 are the same as the connection structure and function between the third clip 124 and the wall of the chassis 200 , and will not be described in detail.

[0121] Thus, in the embodiments of the present application, through the settings of the third buckle 124 and the fourth buckle, the movement of both ends of the circuit board module 100 along the first direction (X) relative to the chassis 200 along the second direction (Z) can be restricted, further making the connection between the circuit board module 100 and the chassis 200 stable. Moreover, both ends of the circuit board 110 module along the first direction (X) are connected to the chassis 200, which can ensure uniform load distribution of the circuit board module 100, thereby avoiding deformation of the circuit board 110 during the use of the circuit board module 100, ensuring stable electrical connection between the hard disk 300 and the circuit board 110, and further enhancing the stability and reliability of the server.

[0122] See Figure 19 , Figure 20 , Figure 21 , in some embodiments, a guiding portion 220 is provided on the chassis 200, and the guiding portion 220 extends along the second direction (Z); along the thickness direction (Y) of the circuit board 110, a guiding hole 116 is provided on one side of the circuit board 110; the guiding hole 116 is for the guiding portion 220 to penetrate along the second direction (Z). Thus, through the settings of the guiding hole 116 and the guiding portion 220, a guiding and positioning effect is formed on the installation of the circuit board module 100, so that the circuit board module 100 can be connected to the chassis 200, and damage to the circuit board 110 caused by misalignment during the installation of the circuit board module 100 can be prevented.

[0123] In some embodiments, at least one of the guiding portion 220 and the hole wall of the guiding hole 116 has a guiding inclined surface 140. Through the setting of the guiding inclined surface 140, a guiding effect is formed for the guiding portion 220 to pass through the guiding hole 116, which is beneficial to the installation and disassembly of the circuit board module 100.

[0124] In some embodiments, there are multiple guiding portions 220, and the multiple guiding portions 220 can be arranged at intervals along the first direction (X). Correspondingly, the number of guiding holes 116 on the circuit board 110 can also be multiple, and the multiple guiding holes 116 are arranged in an array on the circuit board 110. Each column of guiding holes 116 corresponds to the same guiding portion 220 and is for the guiding portion 220 to pass through. In this way, through the settings of the multiple guiding portions 220 and the multiple guiding holes 116, the force distribution of the circuit board module 100 is made uniform, so that the circuit board 110 is supported by the guiding portion 220 in multiple directions, reducing the deformation of the circuit board 110.

[0125] In some embodiments, along the thickness direction (Y) of the circuit board 110, the connection terminal 117 and the guiding hole 116 on the circuit board 110 are located on opposite sides of the circuit board 110. In this way, when the hard disk 300 is plugged into the connection terminal 117, the assembly force between the hard disk 300 and the circuit board 110 and the supporting effect of the guiding portion 220 cancel each other out, thereby preventing the circuit board 110 from deforming, further ensuring the stable electrical connection between the hard disk 300 and the circuit board 110, and enabling the stable operation performance of the server.

[0126] In some embodiments, a stop member is provided inside the chassis 200; along the thickness direction (Y) of the circuit board 110, a connection terminal 117 is provided on one side of the circuit board 110, and the connection terminal 117 is used to connect electrical components, and the side of the circuit board 110 facing away from the connection terminal 117 is for the stop member to stop and cooperate with. In this way, by the stop member stopping on the side of the circuit board 110 facing away from the connection terminal 117, on the one hand, the stop member can prevent the circuit board 110 from flipping around the axis parallel to the first direction (X), and can also form a stopping and supporting effect on the circuit board 110 along the thickness direction (Y) of the circuit board 110, thereby avoiding the mechanical force generated when the electrical components are assembled on the circuit board 110 through the connection terminal 117, which causes the circuit board 110 to deform. In this way, the mechanical connection and electrical connection between the electrical components and the circuit board 110 can be made stable and reliable, and the stable operation of the server can be further ensured.

[0127] See Figure 19 、 Figure 20 、 Figure 22 Optionally, the stop member includes a stop hook 230, and the stop hook 230 is rotatably connected to the box wall of the chassis 200; the stop hook 230 rotates relative to the box wall of the chassis 200 to stop on the side of the circuit board 110 facing away from the connection terminal 117 along the thickness direction (Y) of the circuit board 110.

[0128] It can be understood that the stop hook 230 is rotatably connected to the box wall of the chassis 200, and the stop hook 230 has a stop position and a clearance position. In the stop position, along the thickness direction (Y) of the circuit board 110, the stop hook 230 stops on the side of the circuit board 110 facing away from the connection terminal 117 to support the circuit board 110 through the stop hook 230, avoiding the deformation of the circuit board 110 when the hard disk 300 is connected to the circuit board 110, and improving the connection stability between the circuit board 110 and the hard disk 300.

[0129] In the clearance position, the stop hook 230 is disengaged from the stop relationship with the circuit board 110, facilitating the installation and disassembly of the circuit board module 100 and the chassis 200.

[0130] It should be noted that the stop member(s) can be one or more. When there are multiple stop members, the multiple stop members can be arranged at intervals in the first direction (X) within the chassis 200. The embodiment of the present application does not make specific requirements on the number of stop members.

[0131] In a second aspect, an embodiment of the present application can also provide a server, including: a chassis 200 and a circuit board module 100. The chassis 200 has a receiving cavity; the circuit board module 100 is the circuit board module 100 in any one of the embodiments in the first aspect of the present application, and the circuit board module 100 is arranged in the receiving cavity.

[0132] For the server in the embodiment of the present application, since it includes the circuit board module 100 in any one of the embodiments in the foregoing first aspect, the installation efficiency and maintenance efficiency of the server, as well as the working stability and service performance of the server, can be improved.

[0133] The above has introduced in detail a circuit board module and a server provided by the present application. Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
