[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] It should be noted that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are 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, and therefore cannot be understood as limiting the present application. The terms "installed", "connected" and "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. The terms "parallel", "perpendicular" and "equal" include the situations described and situations similar to the situations described, and the range of the similar situations is within the acceptable deviation range, where the acceptable deviation range is determined by a person of ordinary skill in the art taking into account the measurement being discussed and the errors associated with the measurement of a specific quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range of approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range of approximate equality can be, for example, that the difference between the two equalities is less than or equal to 5% of either one. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0046] First, combining Figure 1 and Figure 2 The 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 arranged in the chassis 200, so as to form a support and connection function for the circuit board module 100 through the chassis 200. The chassis 200 can also be used as a protective structural member of the circuit board module 100 to protect the circuit board module 100, and prevent the circuit board module 100 from entering the chassis 200 due to dust, water vapor, etc. in the external environment of the chassis 200, which affects the heat dissipation performance of the circuit board 110 and the use 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 to electrically connect to 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. The memory can be a hard disk 300, etc., and the embodiment of the present application does not make specific requirements for this.

[0048] When the hard disk 300 is connected to the circuit board 110, different connection terminals 117 can be set on the circuit board 110. The hard disk 300 is connected to the circuit board 110 through the connection terminals 117, so that the circuit board 110 and the hard disk 300 can achieve a stable electrical connection, making the server's data processing and signal interaction more stable.

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

[0050] In the specific implementation process, the assembly force between the interface of different hard disks 300 and the connection terminal 117 is also different. For example, 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, the assembly force will increase, the circuit board 110 will deform abnormally, the engagement distance between the interface of the hard disk 300 and the connection terminal 117 is not enough, so that the electrical connection between the hard disk 300 and the circuit board 110 is abnormal, and the server's data retrieval and storage rate of the hard disk 300 is reduced, affecting the performance and stability of the server.

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

[0052] It is understandable that the increase in the number of screws and the number of screw holes on the circuit board 110 will lead to changes in the wiring layout of the circuit board 110, and the available area of ​​the wiring of the circuit board 110 will be reduced. In order to meet the server's demand for data processing, it is necessary to increase the wiring area of ​​the circuit board 110, so that the wiring layout is reasonable, reduce 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 operating temperature of the circuit board 110 is kept within a stable range, so that the performance of the server is improved. However, as the area of ​​the circuit board 110 increases, it is not conducive to the miniaturization of the server. As the area of ​​the circuit board 110 increases, the deformation of the circuit board 110 also changes, which can easily lead to poor performance of the server.

[0053] To solve the above defects, see Figures 1 to 6 The circuit board module 100 in the embodiment of the present application further includes a first connector 120 and a second connector 130. The first connector 120 and the second connector 130 are disposed at opposite ends of the circuit board 110 along the first direction (X), so as to fix and limit the circuit board 110 through the first connector 120 and the second connector 130, and prevent the circuit board 110 from moving along the first direction (X), so as to 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 as to stabilize the operation of the server and improve the performance of the server.

[0054] In an optional embodiment, the first connector 120 and the circuit board 110 are connected by a snap-fitting manner. In this way, the first connector 120 and the circuit board 110 are connected by a snap-fitting manner, which can reduce the number of screws, so as to facilitate the installation and maintenance of the circuit board 110, thereby improving the installation efficiency and maintenance efficiency of the circuit board 110. As the number of screws is reduced, the available area of ​​the circuit board 110 is increased, and the size of the circuit board 110 can be reduced. On the basis of meeting the performance of the server, the space occupied by the circuit board 110 is reduced, which helps to miniaturize the server, and thus can also reduce the production cost of the server.

[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 to facilitate the installation and disassembly of the circuit board module 100 and the chassis 200, reduce the installation difficulty and maintenance difficulty of the server, and improve 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 in a snap-fit ​​manner, which can reduce the number of screws, so as to facilitate the installation and maintenance of the circuit board 110, thereby improving the installation efficiency and maintenance efficiency of the circuit board 110. As the number of screws is reduced, the available area of ​​the circuit board 110 is increased, and the size of the circuit board 110 can be reduced. On the basis of meeting the performance of the server, the space occupied by the circuit board 110 is reduced, which helps to miniaturize the server, and thus can also reduce the production cost of the server.

[0057] In the embodiment of the present application, along the first direction (X), the side of the second connecting member 130 facing away from the circuit board 110 is connected to the box wall of the chassis 200 in a snap-fit ​​manner to facilitate the installation and disassembly of the circuit board module 100 and the chassis 200, reduce the installation difficulty and maintenance difficulty of the server, and improve the installation efficiency and maintenance efficiency.

[0058] It can be understood that the first connecting member 120 and the second connecting member 130 are connected to the two ends of the circuit board 110 along the first direction (X). Through such a setting, 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, the first direction (X) can be the length direction of the circuit board 110 or the width direction of the circuit board 110. The embodiment of the present application is described by taking the first direction (X) along the length direction of the circuit board 110 as an example. 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 above-mentioned embodiment, the first connector 120 and the second connector 130 are both connected to the circuit board 110 in a snap-fit ​​manner, wherein the results for achieving the snap-fit ​​are various. As an optional embodiment, at least one of the first connector 120 and the second connector 130 has a snap-fit ​​slot, and in the first connector 120, the first connector 120 is connected to the circuit board 110 through the snap-fit ​​slot; in the second connector 130, the second connector 130 is connected to the circuit board 110 through the snap-fit ​​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 the corresponding snap-fit ​​slot, so that the movement of the circuit board 110 is limited by the setting of the snap-fit ​​slot, and the structural stability of the circuit board module 100 is improved. Furthermore, the structure of the snap-fit ​​slot is simple, which facilitates the connection of the first connector 120 and / or the second connector 130 with 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, and improving the production efficiency of the circuit board module 100 and the server.

[0061] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 As an optional implementation, the first connector 120 has a first slot 121 , the first slot 121 extends along a first direction (X), and the first connector 120 and the circuit board 110 are connected via the first slot 121 .

[0062] Exemplarily, the first card slot 121 extends along the first direction (X), and the notch of the first card slot 121 faces the circuit board 110, so that the circuit board 110 shell enters the first card slot 121 along the first direction (X) relative to the first connector 120. When the circuit board 110 is maintained, it is only necessary to move the circuit board 110 along the first direction (X) toward the side where the second connector 130 is located until it is disconnected from the first card slot 121. In this way, through the provision of the first card slot 121, the installation of the circuit board 110 is no longer fixed with screws, which facilitates the installation and removal of the circuit board 110, thereby improving the installation and removal efficiency of the circuit board module 100 and the server, so as to facilitate the maintenance of the circuit board module 100 and the server. In addition, the reduction in the number of screws can increase the available area for routing of the circuit board 110, reduce the structural size of the circuit board 110, and reduce the space occupied by the circuit board 110, thereby contributing to the miniaturization and lightweight of the server.

[0063] It should be noted that, in the embodiment 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, along the first direction (X), the structures of the inner wall of the first card slot 121 and the end surface of the circuit board 110 match each other, 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 with each other. 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, thereby improving the operating reliability of the server.

[0064] Combination Figure 1 , Figure 2 , Figure 4 and Figure 6 In some embodiments, the second connector 130 has a second slot 131 , the second slot 131 extends along the first direction (X), and the second connector 130 and the circuit board 110 are connected through the second slot 131 .

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

[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 first card slot 121 and the second card slot 131 can also limit the movement of the circuit board 110 along the second direction (Z), and limit the rotation of the circuit board 110 around the axis parallel to the first direction (X). In this way, when the hard disk 300 and the circuit board 110 are connected, the circuit board 110 is prevented from being deformed and flipped due to the force applied by the hard disk 300. Therefore, the embodiment of the present application improves the structural stability of the circuit board module 100 through such a first connecting member 120 and the second connecting member 130, 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 embodiment 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. The first direction (X) is along the length direction or width direction of the circuit board 110, and the second direction (Z) is along the width direction or length direction of the circuit board 110. In combination with the above content, the embodiment of the present application takes the first direction (X) along the length direction of the circuit board 110 and the second direction (Z) along the width direction of the circuit board 110 as an example to illustrate the content of the present application. Figure 1 , define the second direction (Z) as Z.

[0068] Furthermore, in an optional implementation of the present application, only the first connector 120 may have the first slot 121 ; or, only the second connector 130 may have the second slot 131 ; or, the first connector 120 may have the first slot 121 , and the second connector 130 may have the second 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 protruding structure, a recessed groove structure, etc., which is not required in the embodiments of the present application.

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

[0072] In some embodiments, see Figure 1 , Figure 2 , Figure 3 and Figure 5 , along the thickness direction (Y) of the circuit board 110, the first stopper 1211 can be protruded relative to the groove wall of the first slot 121, that is, the first stopper 1211 can be a protruding structure, a boss structure, a step structure, etc., which is not required in the embodiment of the present application. Along the first direction (X), the first stopper 1211 matches the shape of the end of the circuit board 110. In this way, through the stopper cooperation between the first stopper 1211 and the circuit board 110, the movement of the circuit board 110 along the first direction (X) is better limited, so that the circuit board module 100 remains stable relative to the chassis 200, so as to improve the operation stability and reliability of the server. It can be understood that through the setting of the first stopper 1211, the first stopper 1211 and the circuit board 110 form a stopper connection relationship in a face-to-face matching manner, which not only limits the movement of the circuit board 110, but also facilitates the installation of the circuit board 110 and the first connector 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 stopper 1211 may be equal to or less than the extension length of the circuit board 110 , and this embodiment of the present application does not limit this.

[0074] Optional, see Figure 1 , Figure 2 , Figure 4 and Figure 6The second card slot 131 has a second stopper 1311 . Along the first direction (X), the second stopper 1311 is located on a side of the second card slot 131 facing the circuit board 110 and stops at an end of the circuit board 110 .

[0075] It should be noted that the structure and function of the second stopper 1311 in the embodiment of the present application are similar to those of the first stopper 1211, and will not be elaborated in this section.

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

[0077] Along the second direction (Z), the extension length of the second stopper 1311 may be less than or equal to the extension length of the notch 111, so that the circuit board 110 and the second stopper 1311 are matched and connected, thereby improving the assembly efficiency of the circuit board module 100. At the same time, the cooperation between the second stopper 1311 and the notch 111 forms a positioning effect for the installation of the circuit board 110, preventing the circuit board 110 from being deformed and damaged due to the matching deviation between the circuit board 110 and the second connector 130, thereby 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 stopper 1311 may be smaller than the extension length of the notch 111 , or greater than the extension length of the notch 111 .

[0079] Among them, when the extension length of the second stop portion 1311 along the thickness direction (Y) of the circuit board 110 is less than the extension length of the notch 111, the second stop portion 1311 still forms a stopping and positioning function of the circuit board 110 by cooperating with the notch 111, but the circuit board 110 is prone to shaking or mis-insertion, and even the circuit board 110 may be deformed.

[0080] When the extension length of the second stopper 1311 is greater than the extension length of the notch 111 along the thickness direction (Y) of the circuit board 110, the second stopper 1311 will cause the groove space of the second slot 131 to increase, so that the circuit board 110 is prone to shaking, and will also cause the circuit board 110 to deform due to uneven force. Furthermore, the groove space of the second slot 131 increases, the structural size of the second connector 130 increases, and the space occupation of the second connector 130 increases, which is not conducive to reducing the space occupation of the circuit board module 100 and the server.

[0081] Therefore, in the embodiment of the present application, along the thickness direction (Y) of the circuit board 110, the extension length of the second stop portion 1311 is equal to the extension length of the notch 111, so that the structure of the circuit board module 100 is stabilized by the cooperation between the second stop portion 1311 and the notch 111, thereby avoiding the reduction in performance of the server caused by the deformation of the circuit board 110.

[0082] For example, the sizes of the circuit board 110 are different, and the two ends of the circuit board 110 along the first direction (X) have multiple clamping sections, and the multiple clamping sections are arranged at intervals along the second direction (Z). The first clamping groove 121 of the first connector 120 and the second clamping groove 131 of the second connector 130 correspond to the clamping sections of the circuit board 110. In this way, through such an arrangement, the circuit board 110 is clamped with the first connector 120 and the second connector 130 at multiple positions, thereby improving the structural stability of the circuit board module 100.

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

[0084] Exemplarily, the clamping portion may be a groove-shaped structure, a step structure, etc., and the embodiments of the present application do not make specific requirements for this. The clamping portion is adapted to the structure on the circuit board and achieves stable clamping.

[0085] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 In some embodiments, the circuit board 110 is provided with a first clamping portion, the first connector 120 is provided with a first clamping buckle 122, and the first connector 120 and the circuit board 110 are connected via the first clamping buckle 122 and the first clamping portion. Thus, the movement of the circuit board 110 along the first direction (X) is further restricted by the clamping cooperation between the first clamping buckle 122 and the first clamping portion, so that the structure of the circuit board module 100 is stable.

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

[0087] Combination Figure 1 , Figure 2 , Figure 4 and Figure 6 In some embodiments, a second clamping portion is provided on the circuit board 110, and a second buckle 132 is provided on the second connecting member 130. The second connecting member 130 and the circuit board 110 are clamped together by the second buckle 132 and the second clamping portion.

[0088] It should be noted that the second clamping portion in the embodiment of the present application has the same structure and function as the first clamping portion, and the second clip 132 has the same structure and function as the first clip 122, which will not be described in detail.

[0089] Exemplarily, the second buckle 132 may 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 clamping portion, or only the second connecting member 130 and the circuit board 110 may be connected through the second buckle 132 and the second clamping portion, or, when the first connecting member 120 and the circuit board 110 are connected through the first buckle 122 and the first clamping portion, the second connecting member 130 and the circuit board 110 are connected through the second buckle 132 and the second clamping portion.

[0091] When the first connecting member 120 and the circuit board 110 are connected by the first clip 122 and the first clip portion, the second connecting member 130 and the circuit board 110 are connected by the second clip 132 and the second clip portion, the first clip 122 and the second clip 132 form tension on the circuit board 110 along the first direction (X), and the load of the circuit board 110 along the first direction (X) is evenly distributed. In this way, the circuit board 110 is not easily deformed, and the electrical connection between the circuit board 110 and the hard disk 300 is stable, which is conducive to improving the reliability and stability of the server, as well as the performance of the server.

[0092] In addition, the embodiment of the present application reduces the number of screws used to fix the circuit board 110 by respectively engaging the first clip 122 and the second clip 132 with the first clip part and the second clip part of the circuit board 110, thereby facilitating the installation and maintenance of the circuit board module 100, reducing the cost and weight of the server, and facilitating the lightweighting of the server.

[0093] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7In some embodiments, the first clamping portion includes a first clamping hole 112, which penetrates the circuit board 110 along the thickness direction (Y) of the circuit board 110; and the first clamping buckle 122 is clamped to the hole wall of the first clamping hole 112 along the first direction (X). In this way, the first clamping buckle 122 cooperates with the hole wall of the first clamping hole 112, which facilitates the connection and disassembly of the circuit board 110 and the first connector 120, thereby improving the installation efficiency and maintenance efficiency of the circuit board module 100. Furthermore, the mutual cooperation between the first clamping buckle 122 and the first clamping hole 112 limits the movement of the circuit board 110 along the first direction (X), limits the movement of the circuit board 110 along the thickness direction (Y) of the circuit board 110, and limits the rotation of the circuit board 110 around an axis parallel to the first direction (X), so that the structure of the circuit board module 100 is stable, and the abnormal electrical connection after the hard disk 300 and the circuit board 110 are connected is prevented, thereby ensuring the stable and reliable operation of the server. In addition, on the basis of meeting the wiring layout requirements, the circuit board 110 reduces the material cost and weight of the circuit board 110 through the provision of the first clamping hole 112, thereby reducing the cost and weight of the server.

[0094] See also Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 In some embodiments, the second clamping portion includes a second clamping hole 113, and the second clamping hole 113 penetrates the circuit board 110 along the thickness direction (Y) of the circuit board 110; along the first direction (X), the second buckle 132 is clamped to the hole wall of the second clamping hole 113.

[0095] It should be noted that the structure and function of the second snap-fit ​​hole 113 in the embodiment of the present application are the same as those of the first snap-fit ​​hole 112 , and the structure and function of the second snap buckle 132 are the same as those of the first snap buckle 122 , which will not be repeated here.

[0096] Optional, see Fig. 9 , Fig.10 , Fig.12 The first clamping portion includes a first protruding extension section 114, and along the second direction (Z), the first protruding extension section 114 is protruding from one side edge of the circuit board 110; along the first direction (X), the first buckle 122 is clamped with the side of the first protruding extension section 114 away from the first connector 120. In this way, the circuit board 110 is fixed by the clamping cooperation between the first clamping portion and the first protruding extension section 114, the number of screws is reduced, the maintenance of the circuit board 110 is facilitated, and the installation and maintenance of the circuit board module 100 are improved.

[0097] It can be understood that for a smaller circuit board 110, if a hole-shaped structure is set on the circuit board 110 and is engaged with the first clip 122, the available wiring area of ​​the circuit board 110 will be reduced. In this way, by setting the first protruding extension section 114, not only can such a problem be solved, but also the installation of the circuit board 110 can be met, avoiding the need to separately set 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 section 114 may be located on any one of the two opposite sides of the circuit board 110 , which is not required in the embodiment of the present application.

[0099] See also Fig. 9 , Fig.11 , Fig.13 In the embodiment of the present application, the second clamping portion includes a second protruding extension section 115, and along the second direction (Z), the second protruding extension section 115 is arranged to protrude from the edge of one side of the circuit board 110; along the first direction (X), the second buckle 132 and the second protruding extension section 115 are clamped with one side away from the second connecting member 130.

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

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

[0102] When the first protruding extension section 114 and the second protruding extension section 115 are located on the same side of the circuit board 110, along the first direction (X), the two ends of the circuit board 110 are respectively provided with the first connector 120 and the second connector 130, so that the load of the circuit board 110 can be evenly distributed, thereby avoiding structural deformation of the circuit board 110 caused by uneven force, 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. Furthermore, the structure of the circuit board 110 is relatively regular, so as to reduce the difficulty of producing the circuit board 110.

[0103] It should be noted that in the embodiment of the present application, the first protruding extension section 114 and the second protruding extension section 115 protrude relative to the circuit board 110 along the second direction (Z) to extend to a length sufficient to ensure stable connection with the corresponding first clip 122 and the corresponding second clip 132, and the embodiment of the present application does not make any requirements for this.

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

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

[0106] Exemplarily, the third clamping portion 123 may be recessed or protruded relative to the surface of the first connecting member 120 facing the wall of the chassis 200, and correspondingly, the fourth clamping portion 210 may be protruded or recessed relative to the surface of the wall of the chassis 200 facing the first connecting member 120. In this way, the movement of the circuit board module 100 along the thickness direction (Y) of the circuit board module 100 is limited by the clamping cooperation between the third clamping portion 123 and the fourth clamping portion 210, and the situation of insufficient distance between the hard disk 300 and the circuit board 110 is prevented, 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 the implementation process, the circuit board module 100 can be installed in the chassis 200 through the relative sliding between the third clamping portion 123 on the first connecting member 120 and the fourth clamping portion 210 on the chassis 200. In this way, through the setting of the third clamping portion 123 and the fourth clamping portion 210, the screws used to fix the circuit board module 100 and the chassis 200 are reduced. This safety method is more convenient, thereby facilitating the installation and maintenance of the circuit board module 100.

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

[0109] 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.

[0110] In the embodiment of the present application, the first connecting member 120 and the chassis 200 are connected to the fourth connecting member 210 via the third clamping portion 123, and the second connecting member 130 and the chassis 200 are connected via the fifth clamping portion and the sixth clamping portion. In this way, the movement and deformation of the circuit board 110 along the thickness direction (Y) of the circuit board 110 are jointly restricted by the arrangement of the first connecting member 120 and the second connecting member 130, 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 working stability and usage performance of the server.

[0111] Combination Fig.14 , Fig.15 , Fig.16 , Fig.17 , Fig.18 The third clamping portion 123 includes a first portion 1231 and a second portion 1232. Along the second direction (Z), the first portion 1231 and the second portion 1232 are arranged sequentially, and along the thickness direction (Y) of the circuit board 110, the extension length of the first portion 1231 is smaller than the extension length of the second portion 1232; the shapes of the fourth clamping portion 210 and the third clamping portion 123 match.

[0112] It can be understood that along the second direction (Z), the third clamping portion 123 forms a structure that is narrow at the top and wide at the bottom through the arrangement of the first part 1231 and the second part 1232. Correspondingly, the fourth clamping portion 210 also has a structure that is narrow at the top and wide at the bottom because it matches the shape of the third clamping portion 123. In this way, the third clamping portion 123 and the fourth clamping portion 210 can slide along the second direction (Z), making the connection between the circuit board module 100 and the chassis 200 more convenient.

[0113] Understandable, see Fig.16 , Fig.17 , Fig.18 The narrower first portion 1231 of the third clamping portion 123 is clamped with the narrower portion of the fourth clamping portion 210, and the wider second portion 1232 of the third clamping portion 123 is clamped with the wider portion of the fourth clamping portion 210, thereby limiting the movement of the circuit board module 100 in the chassis 200 along the thickness direction (Y) of the circuit board 110, so that the connection between the circuit board module 100 and the chassis 200 is stable.

[0114] The fifth clamping portion includes a third part and a fourth part. The third part and the fourth part are arranged sequentially along the second direction (Z), and along the thickness direction (Y) of the circuit board 110, the extension length of the third part is smaller than the extension length of the fourth part; the shapes of the sixth clamping portion and the fifth clamping portion match.

[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 not difficult to understand that the embodiment of the present application limits the movement of the circuit board module 100 in the thickness direction (Y) of the circuit board 110 in the chassis 200 through the third clamping portion 123 on the first connecting member 120 and the fifth clamping portion on the second connecting member 130, which are connected to the chassis 200. In order to prevent the circuit board module 100 from moving relative to the chassis 200 along the first direction (X), causing the circuit board module 100 and the chassis 200 to be disconnected. In the embodiment of the present application, along the first direction (X), the side of the first connecting member 120 away from the circuit board 110 is provided with a third clamping buckle 124; along the thickness direction (Y) of the circuit board 110, the third clamping buckle 124 is located on the side of the third clamping portion 123 away from the circuit board 110; the third clamping buckle 124 is used to clamp with the box wall of the chassis 200 along the first direction (X).

[0117] Illustratively, the case wall of the chassis 200 has a protrusion structure or a step structure for the third buckle 124 to be snapped into the chassis 200 .

[0118] In some embodiments, the third buckle 124 may be an elastic buckle, so that the elastic force of the elastic buckle 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 buckle is provided on the side of the second connecting member 130 away from the circuit board 110 along the first direction (X); along the thickness direction (Y) of the circuit board 110, the fourth buckle is located on the side of the fifth buckle away from the circuit board 110; the fourth buckle is used to be buckled 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 buckle and the box wall of the chassis 200 are the same as the connection structure and function between the third buckle 124 and the box wall of the chassis 200, which will not be described in detail.

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

[0122] See also Fig.19 , Fig. 20 , Fig.21 In some embodiments, a guide portion 220 is provided on the chassis 200, and the guide portion 220 extends along the second direction (Z); a guide hole 116 is provided on one side of the circuit board 110 along the thickness direction (Y) of the circuit board 110; the guide hole 116 is used for the guide portion 220 to penetrate along the second direction (Z). In this way, the installation of the circuit board module 100 is guided and positioned by the provision of the guide hole 116 and the guide portion 220, so that the circuit board module 100 and the chassis 200 are connected, and the circuit board module 100 is prevented from being damaged by the circuit board 110 due to misalignment during installation.

[0123] In some embodiments, at least one of the guide portion 220 and the hole wall of the guide hole 116 has a guide slope 140. The guide slope 140 is provided to guide the guide portion 220 through the guide hole 116, which facilitates the installation and removal of the circuit board module 100.

[0124] In some embodiments, there are multiple guide parts 220, and the multiple guide parts 220 can be arranged at intervals along the first direction (X). Accordingly, the number of guide holes 116 on the circuit board 110 can also be multiple, and the multiple guide holes 116 are distributed in an array on the circuit board 110. The guide holes 116 in each column correspond to the same guide part 220 and are passed through by the guide part 220. In this way, through the arrangement of multiple guide parts 220 and multiple guide holes 116, the force distribution of the circuit board module 100 is uniform, so that the circuit board 110 is supported by the guide parts 220 in multiple directions, and the deformation of the circuit board 110 is reduced.

[0125] In some embodiments, along the thickness direction (Y) of the circuit board 110, the connection terminal 117 and the guide 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 and the connection terminal 117 are plugged in, the assembly force between the hard disk 300 and the circuit board 110 and the supporting effect of the guide portion 220 offset each other, thereby preventing the circuit board 110 from being deformed, further ensuring the stability of the electrical connection between the hard disk 300 and the circuit board 110, and making the working performance of the server stable.

[0126] In some embodiments, a stopper is provided in 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 the electrical component, and the side of the circuit board 110 away from the connection terminal 117 is used for the stopper to stop and cooperate. In this way, the stopper stops at the side of the circuit board 110 away from the connection terminal 117, and on the one hand, the circuit board 110 can be prevented from turning around the axis parallel to the first direction (X) by the stopper, and the stopper can also form a stopping effect and a supporting effect on the circuit board 110 along the thickness direction (Y) of the circuit board 110, thereby avoiding the deformation of the circuit board 110 caused by the mechanical force generated when the electrical component is assembled on the circuit board 110 through the connection terminal 117, so that the mechanical connection and electrical connection between the electrical component and the circuit board 110 can be stable and reliable, further ensuring the stable operation of the server.

[0127] See also Fig.19 , Fig. 20 , Fig. 22 Optionally, the stopper includes a stop hook 230, which is rotatably connected to the wall of the chassis 200; the stop hook 230 rotates relative to the wall of the chassis 200 to stop at the side of the circuit board 110 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 wall of the chassis 200, and the stop hook 230 has a stop position and an escape position. When at the stop position, along the thickness direction (Y) of the circuit board 110, the stop hook 230 stops at the side of the circuit board 110 away from the connection terminal 117, so as to support the circuit board 110 through the stop hook 230, thereby avoiding deformation of the circuit board 110 when the hard disk 300 and the circuit board 110 are connected, and improving the connection stability between the circuit board 110 and the hard disk 300.

[0129] In the clearance position, the stopping hook 230 and the circuit board 110 are out of the stopping relationship, which facilitates the installation and removal of the circuit board module 100 and the chassis 200.

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

[0131] In a second aspect, the embodiment of the present application may further provide a server, comprising: 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 embodiment of the first aspect of the present application, and the circuit board module 100 is disposed in the receiving cavity.

[0132] The server in the embodiment of the present application includes the circuit board module 100 in any one of the embodiments of the first aspect described above, and therefore, the installation efficiency and maintenance efficiency of the server, as well as the working stability and usage performance of the server can be improved.

[0133] The above is a detailed introduction to a circuit board module and a server provided by the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
