Description

Technical Field

[0001] This utility model relates to an electronic device, and more particularly to a pre-fixed structure for a PCB board. Background Technology

[0002] For PCB assembly processes, it is often required that the PCB mounting direction be perpendicular to the plane of the PCB to facilitate the positioning and fixing of the PCB with the mounting components, such as assembly frames, housings, or covers.

[0003] The current conventional design method involves pre-fixing the PCB board to the mounting components using plastic clips. This means that plastic clips are placed on the mounting components and corresponding to both sides of the PCB board to achieve pre-fixation. When the PCB board and the plastic clips are engaged, a uniform force needs to be applied vertically to the PCB board to ensure that multiple plastic clips engage with the PCB board simultaneously. This avoids difficulties in assembling some clips due to PCB board misalignment. Finally, the PCB board and the mounting components are officially fixed together using evenly distributed screws.

[0004] Its shortcomings are: 1. When assembling plastic clips, the PCB needs to be subjected to a relatively uniform force. Usually, both hands need to be used at the same time to ensure that both sides of the PCB are subjected to force simultaneously in order to achieve this requirement, which is not convenient to operate.

[0005] 2. When there are elastic structures such as springs on the PCB, the force direction of the PCB is consistent with the assembly direction. The plastic clips are elastic and easily deformable, which makes the connection strength between the plastic clips and the PCB board insufficient. The clips used for pre-fixation are easy to loosen, resulting in the PCB board not being effectively pre-fixed. Utility Model Content

[0006] The purpose of this invention is to provide a pre-fixed structure suitable for assembling PCBs at an inclined angle, making PCB installation and fixing more convenient, and allowing PCBs to be installed and fixed with one hand.

[0007] The purpose of this utility model is achieved as follows: a pre-fixed structure suitable for assembling PCB boards at an inclined angle includes a PCB board fixed to a mounting component. The PCB board and the mounting component are connected and fixed by locking screws. One side of the surface of the mounting component is provided with an L-shaped protrusion and a limiting protrusion. An insertion port for accommodating the edge of the PCB board is left between the L-shaped protrusion and the limiting protrusion. The other side of the surface of the mounting component corresponding to the insertion port is provided with a buckle. When one edge of the PCB board is inserted into the insertion port and the other end is pressed towards the buckle, the hook on the buckle hooks the other edge of the PCB board.

[0008] When installing and securing the PCB board to the mounting components, first insert one end of the PCB board into the socket, then press the other end of the PCB board downwards so that the hook on the clip precisely engages the edge of the other end of the PCB board. This process can be completed with just one hand, achieving pre-fixation of the PCB board. Then, the PCB board is further secured to the mounting components using locking screws, completing the PCB board installation. When the PCB board has elastic components, placing them near the L-shaped protrusions ensures adequate pre-fixation. This device is particularly suitable for automotive electronic equipment, facilitating both factory installation and subsequent maintenance.

[0009] To further facilitate the pre-positioning and installation of the PCB board, the surface of the mounting component is provided with protruding positioning posts, and the PCB board is provided with corresponding waist-shaped holes. When one edge of the PCB board is inserted into the socket and the other end is pressed in the buckling direction, the positioning post is precisely inserted into the waist-shaped hole.

[0010] To facilitate the installation of the PCB board and achieve positioning of both sides of the PCB board, two raised side baffles are provided on the surface of the mounting component at the end corresponding to the L-shaped protrusion. When one edge of the PCB board is inserted into the socket, the two sides adjacent to one end of the PCB board are precisely locked between the two side baffles.

[0011] Furthermore, two L-shaped protrusions and two limiting protrusions are provided on one side of the surface of the mounting component, and two snap fasteners are also provided on the other side of the surface of the mounting component. This design allows for stable pre-fixing as well.

[0012] To ensure the pre-positioning of the PCB board end, an end baffle is provided on the surface of the mounting component and between the two clips.

[0013] To facilitate the pre-fixation of the PCB board to the hook of the clip, the protruding top of the end baffle is provided with an inclined guide. When the PCB board is pressed down, under the action of the guide, the PCB board can move downward and toward the insertion end, thereby making it easier to connect with the hook of the clip.

[0014] Furthermore, the surface of the mounting component is provided with a plurality of protruding screw mounting seats, the height of which is the same as the height of the limiting protrusion. The lower side of the PCB board is supported on the screw mounting seats, and the upper side of the PCB board is connected and fixed to the screw mounting seats by the locking screws.

[0015] Furthermore, the height of the limiting protrusion is not higher than the height of the screw mounting base. This ensures that when the PCB board is fixed with the screws, the limiting protrusion does not affect the PCB board, and the lower side of the PCB board is supported on the screw mounting base.

[0016] To facilitate PCB board insertion, the inner side of the socket formed by the L-shaped bump and the limiting protrusion is chamfered.

[0017] For ease of fixing, the PCB board is rectangular in shape. Attached Figure Description

Detailed Implementation

[0028] like Figure 1-9 As shown, a pre-fixed structure suitable for assembling PCB boards at an inclined angle is provided, including a PCB board 5 fixed to a mounting component 1. The PCB board 5 and the mounting component 1 are connected and fixed by locking screws 6. One side of the surface of the mounting component 1 is provided with an L-shaped protrusion 2 and a limiting protrusion 11. An insertion port 12 is provided between the L-shaped protrusion 2 and the limiting protrusion 11 to accommodate the edge of the PCB board 5. The other side of the surface of the mounting component 1 corresponding to the insertion port 12 is provided with a buckle 7. When one edge of the PCB board 5 is inserted into the insertion port 12 and the other end is pressed towards the buckle 7, the hook 7a on the buckle 7 hooks the other edge of the PCB board 5.

[0029] When installing and fixing the PCB board 5 to the mounting component 1, first insert one end of the PCB board 5 into the socket 12, then press the other end of the PCB board 5 downwards so that the hook 7a on the clip 7 hooks precisely onto the edge of the other end of the PCB board 5. This operation can be completed with just one hand, thus achieving pre-fixation of the PCB board 5. Then, the PCB board 5 is further fixed to the mounting component 1 using the locking screw 6, completing the installation of the PCB board 5. When the PCB board 5 has elastic components, these components can be positioned near the L-shaped protrusion 2 to ensure adequate pre-fixation.

[0030] To further facilitate the pre-positioning and installation of the PCB board 5, the surface of the mounting component 1 is provided with a protruding positioning post 4, and the PCB board 5 is provided with a corresponding oblong hole 9. When one edge of the PCB board 5 is inserted into the socket 12 and the other end is pressed towards the buckle 7, the positioning post 4 is precisely inserted into the oblong hole 9. To facilitate the positioning post 4 entering the oblong hole 9, the top of the positioning post 4 is set in a conical shape.

[0031] To facilitate the installation of PCB board 5 and achieve positioning of both sides of PCB board 5, two raised side baffles 3 are provided on the surface of the mounting component 1 at the end corresponding to the L-shaped protrusion 2. When one edge of PCB board 5 is inserted into the socket 12, the two sides adjacent to one end of PCB board 5 are precisely locked between the two side baffles 3.

[0032] Furthermore, two L-shaped protrusions 2 and two limiting protrusions 11 are provided on one side of the surface of the mounting component 1, and two snap fasteners 7 are also provided on the other side of the surface of the mounting component 1. This design allows for stable pre-fixing as well.

[0033] To ensure the pre-positioning of the ends of the PCB board 5, an end baffle 8 is provided on the surface of the mounting component 1 and between the two clips 7.

[0034] To facilitate the pre-fixation of the PCB board 5 with the hook 7a of the buckle 7, the top of the protruding end baffle 8 is provided with an inclined guide portion 8a. When the PCB board 5 is pressed down, under the action of the guide portion 8a, the PCB board 5 can move downward and toward the insertion end 12, thereby making it easier to connect with the hook 7a of the buckle 7.

[0035] Furthermore, the surface of the mounting component 1 is provided with a plurality of protruding screw mounting seats 10, the height of the screw mounting seats 10 being the same as the height of the limiting protrusion 11, the lower side of the PCB board 5 being supported on the screw mounting seats 10, and the upper side of the PCB board 5 being connected and fixed to the screw mounting seats 10 by locking screws 6.

[0036] Furthermore, the height of the limiting protrusion 11 is not higher than the height of the screw mounting base 10. This ensures that when the PCB board 5 is fixed by the locking screw 6, the limiting protrusion 11 does not affect the PCB board 5, and the lower side of the PCB board 5 is supported on the screw mounting base 10.

[0037] To facilitate the insertion of the PCB board 5, the inner side of the socket 12 formed by the L-shaped bump 2 and the limiting protrusion 11 is chamfered.

[0038] For ease of fixing, PCB board 5 is rectangular in shape.

[0039] This device is particularly suitable for in-vehicle electronic equipment, facilitating both factory installation and subsequent maintenance. The advantages of this device include: 1. Easy to operate and supports one-handed operation: The simple process of inserting and pressing greatly improves installation efficiency, especially in environments with limited space or requiring batch assembly.

[0040] 2. Effective protection of components: The pre-fixed structure prevents the PCB board from shifting or shaking during screw tightening, providing excellent protection for sensitive elastic components and solder joints on the board.

[0041] 3. Precise and reliable positioning: Through multiple positioning methods such as the socket, side baffle, positioning post and buckle, the PCB board is accurately positioned in three-dimensional space (X, Y and Z directions), which lays a solid foundation for subsequent electrical connection and mechanical fixation.

[0042] 4. Improved maintenance efficiency: When repairs are needed, the disassembly process is equally simple. Just unscrew the screws and release the clips, which facilitates on-site maintenance.

[0043] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
