Description

Technical Field

[0001] This utility model relates to the field of housing component technology, specifically a circuit board housing component. Background Technology

[0002] In the design and manufacturing of electronic and mechanical equipment, the installation and fixation of internal components such as circuit boards, sensors, and controllers is a critical step. Especially when two circuit boards are involved, traditional methods typically rely on multiple screw holes and supports to ensure stability and accurate positioning between the layers. However, this method not only increases assembly complexity but also leads to inconvenience during maintenance and repair, while consuming valuable internal space. To address these issues, there is an urgent need for a new fixing solution that simplifies the assembly process, reduces the number of required parts, eliminates the need for additional support structures, and facilitates quick installation and disassembly, thereby achieving more efficient space utilization, improved maintenance convenience, and ensuring long-term stability. This improved installation and fixing method is particularly suitable for scenarios involving two or more layers of circuit boards. By employing innovative mechanisms such as integrated brackets, flexible clamps, or snap-fit ​​designs, circuit board installation and replacement can be easily completed without tools, significantly improving work efficiency. This method is applicable not only to various industries such as consumer electronics, industrial control systems, medical equipment, and communication facilities but also enhances product assembly efficiency, user experience, and market competitiveness.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0017] Reference Figure 1-3 According to an embodiment of the present invention, a circuit board housing component includes a base housing 1. The base housing 1 has a vertically penetrating mounting cavity 3. The mounting cavity 3 has symmetrically arranged locking mechanisms on its upper and lower sides. These symmetrically arranged locking mechanisms ensure simultaneous installation of two circuit boards, maintain operational consistency, simplify the operation process, and improve work efficiency. The base housing 1 also has symmetrically arranged protective plates 13 on its upper and lower sides. The locking mechanisms include symmetrically arranged inner recesses 9 that communicate with the mounting cavity 3, and symmetrically arranged outer recesses on both sides. A base support block 7 is provided and fixedly connected to the wall of the mounting cavity 3. A rotating arm 10 is provided in the inner recess 9. One end of the rotating arm 10 is rotatably connected to the wall of the inner recess 9 through a rotating shaft 11. A clamp 15 extending into the mounting cavity 3 is fixedly provided at the end of the rotating arm 10 away from the rotating shaft 11. A pressure spring 14 is provided between the rotating arm 10 and the wall of the inner recess 9. A threaded sleeve 19 is fixedly provided in the top wall of the inner recess 9. A first inclined surface 16 and a second inclined surface 17 are provided on the clamp 15.

[0018] Advantageously or exemplaryly, a connector 2 is fixedly provided on the front end face of the base housing 1. By placing the connector on the front side of the base housing, users or technicians can more conveniently perform power and signal line connection operations without having to go around to the back of the device or other hard-to-access locations, thus improving installation efficiency.

[0019] Beneficially or exemplaryly, the inner walls of the mounting cavity 3 are symmetrically provided with through grooves 4. The through groove 4 on the left is provided with a dustproof net 12, and the through groove 4 on the right is provided with a miniature cooling fan 5. The miniature cooling fan on the right can actively draw in air to form an airflow, which helps to dissipate heat from the internal electronic components or mechanical parts and prevents performance degradation or damage caused by overheating.

[0020] Advantageously or exemplaryly, a circuit board component 6 is placed on the base block 7, and the circuit board component 6 has beveled notches 20 on the left and right sides.

[0021] Advantageously or exemplaryly, the protective plate 13 is connected to the threaded sleeve 19 by bolts 18. The engagement of the bolts and the threaded sleeve can provide strong mechanical strength, ensuring that the protective plate will not loosen or fall off when subjected to external impact or vibration, thereby improving the stability of the overall structure.

[0022] In use, the rotating arm 10 is subjected to the pressure of the top spring 14, which keeps the clamping head 15 inserted into the mounting cavity 3 to its maximum extent. At this time, the side of the circuit board 6 with electronic components is oriented towards the center of the mounting cavity 3, and then it is moved downwards, so that the circuit board 6 abuts against the first inclined surface 16 on the clamping head 15. This causes the clamping head 15 to overcome the pressure of the top spring 14 and move into the inner recess 9. When the circuit board 6 moves below the clamping head 15, the rotating arm 10 is again subjected to the pressure of the top spring 14. The top pressure causes the clamp 15 to extend into the mounting cavity 3 to the maximum extent, and the second inclined surface 17 to abut against the inclined surface notch 20, thereby temporarily fixing the circuit board 6. Then, the protective plate 13 is removed, and the bolt 18 is tightened to secure the protective plate 13 to the base housing 1. At the same time, the bolt 18 is inserted into the inner recess 9 on the side away from the protective plate 13, and the bolt 18 abuts against the clamp 15, thereby locking the clamp 15 and thus securing the circuit board 6.

[0023] When disassembly is required, remove bolt 18 and take off protective plate 13 to release the locking state of clamp 15. At this time, since the circuit board 6 is in a temporary fixed state, the circuit board 6 will not fall off by itself, which improves safety and convenience. Then pull the circuit board 6 outward from the base housing 1, so that the clamp 15 overcomes the top pressure of the top pressure spring 14 and moves into the inner recess 9. When the circuit board 6 is away from the clamp 15, the disassembly and assembly of the circuit board 6 can be carried out.

[0024] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of this utility model. All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
