[0002] In conventional PCBA (Printed Circuit Board Assembly), boards such as SSD (Solid State Drive) cards are usually fixed using threaded connections. However, with the connector position fixed, considering that different models and specifications of boards usually have different height dimensions, it is necessary to use an additional steel plate for conversion. At this time, the installation of different specifications of boards usually requires a separate steel plate to be designed. This method is not only costly, but also has limitations on the height of the connector selection and poor versatility. Summary of the Invention

[0031] 200. Connecting components. Detailed Implementation

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Referring to Figures 1 to 4, an embodiment of the first aspect of this application discloses a board fixing structure, including a housing 100 and a connecting component 200.

[0034] Specifically, at least two mounting spaces 110 are provided on the housing 100 at intervals, and the at least two mounting spaces 110 are respectively used to fix boards of the same or different specifications; the connecting component 200 is used to install the housing 100, and the housing 100 can be adjusted relative to the connecting component 200 before installation is completed so that one of the mounting spaces 110 is in a preset installation position.

[0035] In the embodiments of this application, by providing an installation space 110 on the housing 100 that can fix boards of the same or different specifications, when fixing boards of different heights at the same position using this board fixing structure, the orientation of the housing 100 is adjusted so that the corresponding installation space 110 matches the corresponding board, and the installation is achieved by fixing the position with the connecting component 200, thereby improving the compatibility of the structure and reducing the production cost.

[0036] It should be understood that when circuit boards such as SSD cards are installed on a PCBA, one end of the board is connected to a connector, while the other end requires a fixing structure for fixation. To ensure compatibility with different specifications of circuit boards, this application aims to use a single fixing structure for boards at the same location but different heights, thereby reducing costs. Based on this, before completely fixing the housing 100 to the appropriate position on the PCBA using the connecting component 200, this application adjusts the mounting orientation of the housing 100 based on the relative height of the board to be fixed, ensuring that the mounting space 110 corresponding to that relative height is in the mounting position. This mounting space 110 is used to fix the other end of the board, and then the connecting component 200 is installed in place to fix the housing 100, thus achieving the effect of mounting the board on the PCBA.

[0037] It is understood that in some embodiments, the arrangement of two adjacent mounting spaces 110 being spaced apart from each other can, on the one hand, reserve space for the housing 100 to adjust its orientation, avoiding or reducing the occurrence of collisions between the board and the housing 100; on the other hand, after one mounting space 110 is fixed with the board that needs to be fixed, the remaining mounting spaces 110 can be used to fix boards of other specifications. Based on the spacing between two adjacent mounting spaces 110, adjacent boards will not interfere with each other during installation, so that the mounting space 110 can be fully utilized and the boards on the PCBA can be arranged more compactly.

[0038] In some embodiments, the mounting space 110 is used to fix one end or one side of the board. Therefore, the size and dimensions of the mounting space 110 need to be adjusted synchronously in conjunction with the fixing position of the board and the setting position of the connecting component 200 to ensure that the mounting space 110 can accommodate the one end or one side of the board to be fixed. In this way, by limiting the size, the inner wall used to form the mounting space 110 can be used to achieve the effect of limiting and fixing the board.

[0039] In some embodiments, the installation space 110 can be set to a space range larger than the size of one end or one side of the board, and corresponding connectors or limiting members are provided on the installation space 110. Then, corresponding mating structures are provided at the corresponding positions of the board, so that after the end or one side of the board to be fixed is set in the installation space 110, the fixing effect is achieved by using the connectors or limiting members to cooperate with the corresponding mating structures.

[0040] It is understood that the connecting component 200 is used to fix the housing 100 to the PCBA or the internal structure of the device, thereby achieving the effect of mounting the circuit board on the PCBA. Before fixing one end of the circuit board in the mounting space 110 of the housing 100, the orientation needs to be adjusted. Therefore, before fixing the housing 100, relative movement can occur between the housing 100 and the connecting component 200. In some embodiments, the housing 100 and the connecting component 200 are connected by a detachable connection. When the housing 100 and the connecting component 200 are relatively separated, their orientation can be better adjusted. After the housing 100 is adjusted to a suitable orientation, the connecting component 200 is then installed on the housing 100 and the housing 100 is fixed in a suitable position. In some embodiments, the housing 100 and the connecting component 200 are connected by a movable connection. The housing 100 can be adjusted relative to the connecting component 200. When the orientation is adjusted to a suitable position, the connecting component 200 is positioned and the housing 100 is fixed while maintaining the orientation. Specifically, the movable connection methods include common movable methods such as translation, rotation or swing, and the movable method can be adaptively adjusted provided that the installation space 110 can be adjusted to the preset installation position.

[0041] It should be noted that the board fixing structure of this application solves the problem of material consistency due to different card heights by using at least two installation spaces 110. At the same time, the two installation spaces 110 are set on the housing 100, and the orientation of the installation space 110 is adjusted before the connecting component 200 fixes the housing 100 to make the installation space 110 fit the corresponding board, thereby solving the problem of high cost caused by the use of adapter steel sheets in related technologies.

[0042] The board fixing structure disclosed in the embodiments of this application will be explained and described in detail below with reference to Figures 1 to 4.

[0043] While utilizing the inner wall of the installation space 110 to achieve the effect of limiting and fixing the board, in order to solve the technical problem of material consistency due to different card heights, in some embodiments of this application, as shown in Figure 1, at least two installation spaces 110 are staggered along the height direction of the housing 100.

[0044] It is understandable that by setting multiple installation spaces 110 staggered in the height direction, the different installation spaces 110 of the board fixing structure can be used to fix the plug-in cards of different heights, thereby solving the problem of poor material consistency.

[0045] Furthermore, while utilizing the inner wall of the installation space 110 to achieve the effect of limiting and fixing the board, in order to further solve the problem that one adapter steel sheet can only correspond to the fixing of one board, resulting in high cost, in some embodiments of this application, as shown in Figure 2, at least two installation spaces 110 are located in the same plane in the height direction of the vertical housing 100.

[0046] Understandably, the high cost problem can be solved by setting multiple mounting spaces 110 on a single board mounting structure to fix multiple boards respectively.

[0047] It should be noted that when the board fixing structure of this application is actually used on the PCBA, the position of the installation space 110 is designed and determined in advance according to the designed product structure, and the structure shown in Figure 1 and / or Figure 2 is flexibly selected to adaptably meet the product assembly requirements.

[0048] In some embodiments, the housing 100 is provided with a plurality of mounting spaces 110, some of which are located in the same plane in the height direction perpendicular to the housing 100, while other mounting spaces 110 are staggered along the height direction of the housing 100. This not only further solves the problem of high cost caused by one adapter steel sheet being able to correspond to only one card, but also allows different mounting spaces 110 to be used to fix cards of different heights, thereby solving the problem of poor material consistency.

[0049] In some specific embodiments, referring to Figures 3 and 4, the PCBA is provided with two board fixing structures. The mounting space 110 on one board fixing structure is offset along the height direction of the housing 100, and the mounting space 110 on the other board fixing structure is in the same plane in the height direction perpendicular to the housing 100. The two board fixing structures are used to connect and fix adjacent boards.

[0050] It should be understood that the structural design of the installation space 110 is key to achieving the above functions in order to better fix the board and make installation more convenient.

[0051] In some embodiments of this application, at least a portion of the mounting space 110 is a slot, which is formed on the circumferential sidewall of the housing 100. It is understood that fixing one end of the card to the inner wall of the mounting slot not only enhances structural stability and damage resistance but also simplifies the installation process and flexibly adapts to various scenarios and adjustment needs.

[0052] In other embodiments, the installation space 110 may be a space enclosed or defined by structural members or connectors, and the same fixing effect can be achieved by using structural members or connectors to limit the position of the board.

[0053] Furthermore, the slot is an arc-shaped slot. While ensuring the limiting and fixing effect, the arc-shaped slot can also avoid the board by rotating and adjusting the shell by 100 degrees, thus avoiding or reducing the occurrence of structural interference.

[0054] In one specific embodiment, at least two mounting spaces 110 have the same structure. It is understood that, considering that the differences between different specifications of boards are mostly in the height position after being connected to the connector, it is sufficient to process mounting spaces 110 with the same structure on the housing 100 to meet the usage requirements most of the time and achieve the effect of simplifying the processing procedure.

[0055] In some embodiments of this application, a mounting hole 120 is formed on the housing 100, and a connecting member 200 is disposed through the mounting hole 120. The connecting member 200 is used to define the orientation of the housing 100 after it is installed. It is understood that during installation, the connecting member 200 passes through the mounting hole 120 and the connection position on the PCBA and pre-positions the housing 100. After the housing 100 is adjusted to the correct orientation, the connecting member 200 is securely installed on the connection position on the PCBA, thereby achieving the effect of defining the orientation of the housing 100 after it is installed.

[0056] In some embodiments, the housing 100 may be provided with common positioning structures such as bosses and guide posts, and corresponding mating structures may be provided at the corresponding positions on the PCBA, so that the housing 100 can be more easily pre-positioned to the position of the connection position, thereby improving the installation efficiency of the connection component 200.

[0057] In one specific embodiment, the mounting hole 120 is located at the center of the housing 100, and at least two mounting spaces 110 are arranged opposite each other on the circumferential sidewall of the housing 100 with the mounting hole 120 as the center. It is understood that the mounting hole 120 being located at the center of the housing 100 allows the housing 100 to rotate around the connecting member 200, and the oppositely arranged mounting spaces 110 facilitate the sequential placement of circuit boards.

[0058] In one specific embodiment, the connecting component 200 is a threaded fastener, and the housing 100 can be adjusted in orientation before the threaded fastener is tightened, facilitating both rotational adjustment and easy fixation. Furthermore, the threaded connection method eliminates the need for structural modifications to the PCBA, saving costs.

[0059] In other embodiments, the connecting component 200 can be adapted to the structure of the PCBA to be a common connecting component such as a pin or a snap fastener. If necessary, the mounting hole 120 of the housing 100 can be adapted to meet the usage requirements of first rotating and adjusting, and then installing and fixing.

[0060] It should be understood that in the embodiments of this application, multiple installation spaces 110 are formed on the housing 100, which may affect the installation efficiency when searching for a suitable orientation during use.

[0061] In some embodiments of this application, the housing 100 is provided with a pointing structure 130, which is located between two installation spaces 110. The pointing structure 130 serves as an identifier to remind technicians, enabling them to promptly determine the board specifications corresponding to the installation space 110 during installation, thereby improving installation efficiency.

[0062] Specifically, the pointing structure 130 can be a foolproof block, an indicator graphic, or an indicator text, etc., which can prompt technicians and improve efficiency by specifying appropriate usage logic or user manual.

[0063] The board fixing structure of this application embodiment is described in detail below with a specific example. It should be noted that the following embodiment is only an exemplary description and should not be construed as limiting the embodiments of this application.

[0064] Referring to Figures 1 to 4, in this embodiment of the board fixing structure, a mounting hole 120 extending along the height direction is formed at the center of the housing 100. This mounting hole 120 is used to install threaded fasteners. The threaded fasteners allow the housing 100 to be installed in a suitable position, thereby placing the board to be fixed onto the PCBA. To address the high cost of adapter steel sheets in related technologies, the housing 100 of this application has two slots on its circumferential sidewall as mounting spaces 110. Furthermore, to solve the problem of material consistency due to different card heights, the slots are staggered along the height direction of the housing 100, so that each slot is at a different relative height position on the housing 100 and is compatible with fixing different specifications of boards. When installing small cards of different heights at the same position, the housing 100 is first pre-positioned in a suitable position using threaded fasteners. Then, the housing 100 is rotated by a certain angle until the corresponding slot can accommodate and fix the board. Finally, the threaded fasteners are tightened to fix the housing 100, thus ensuring compatibility with the fixing of various small cards and enabling its application in similar products.

[0065] The second aspect of this application discloses a PCBA, which is short for Printed Circuit Board Assembly. PCBA refers to the process of mounting electronic components onto a printed circuit board (PCB) using surface mount technology (SMT) or through-hole technology (DIP), and then soldering them to form a complete circuit system. The PCBA can be a mobile phone PCBA, a PC computer PCBA, a server PCBA, an automotive PCBA, etc. The PCBA includes: the board fixing structure of the first aspect of this application.

[0066] The electronic device according to the third aspect of this application may be a smartphone, computer, smart home device, vehicle or automation device, etc., and the electronic device includes: the PCBA according to the second aspect of this application.

[0067] It is easy to understand that the PCBA in the second aspect embodiment of this application and the electronic device in the third aspect embodiment of this application both have the technical effects of the board fixing structure in the first aspect embodiment, and therefore will not be described again.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0069] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0070] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
