Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board structure technology, and in particular to a shockproof and pressure-resistant circuit board structure. Background Technology
[0002] Circuit boards are named as follows: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, PCB, ultra-thin circuit board, printed circuit board (copper etching technology), etc. Circuit boards miniaturize and visualize circuits, playing an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. In existing technologies, because circuit boards generally have many electronic components soldered on them during use, they are easily subjected to external impacts and collisions during installation and use, which can cause electronic components to loosen or fall off, leading to circuit board failure and ultimately causing malfunctions in the entire electronic device.
[0003] Chinese Patent Announcement No.: CN220235058 U, Announcement Date: December 22, 2023. This utility model proposes a shock-resistant and pressure-resistant circuit board structure, including: a circuit board body, a buffer enclosure groove, a shock-resistant base plate, and a spring telescopic shaft. The inner diameter surface of the buffer enclosure groove mates with the outer diameter surface of the circuit board body. The circuit board body is embedded in the buffer enclosure groove, with its top surface exposed outside the groove. The spring telescopic shaft passes through the buffer enclosure groove and the shock-resistant base plate. A shock-resistant top plate is detachably connected to the inner diameter surface of the buffer enclosure groove. The drawback of this technical solution is that each shock-resistant top plate is prone to breakage under gravity, causing the circuit board below to be unable to withstand the pressure and break.
[0004] In summary, the existing structure has the drawback of low pressure resistance, which makes the circuit board prone to breakage. Utility Model Content
[0005] This invention aims to overcome the shortcomings of existing technologies where low structural pressure resistance leads to easy breakage of circuit boards. It provides a shockproof and pressure-resistant circuit board structure that improves the structural pressure resistance and protects the circuit board from breakage.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A shockproof and pressure-resistant circuit board structure includes a central support with a circuit board body inserted inside; a pressure-resistant top plate detachably connected to the upper end of the central support; a pressure-resistant bottom plate detachably connected to the lower end of the central support; corner protectors with mounting grooves at the corners of the surfaces of both the pressure-resistant top and bottom plates, and corner protectors engaging with the mounting grooves; reinforcing ribs connected to the central support, with positioning grooves on both the pressure-resistant top and bottom plates, and reinforcing ribs embedded in the positioning grooves; and reinforcing slats connected to both the pressure-resistant top and bottom plates.
[0007] The circuit board is supported by inserting into a central bracket. A pressure-resistant top plate is connected to the upper end of the central bracket to provide pressure protection for the upper side of the circuit board, while a pressure-resistant bottom plate is connected to the lower end of the central bracket to provide pressure protection for the lower side of the circuit board. The circuit board is placed flat within the central bracket to ensure maximum pressure protection area. Anti-collision corner pads are installed in mounting grooves at the corners where the pressure-resistant top plate and the central bracket, and the pressure-resistant bottom plate and the central bracket are connected, to weaken the sharp corners, improve safety, and prevent stress concentration leading to impact damage. Reinforcing ribs are added at the joints where the pressure-resistant top plate and the central bracket, and the pressure-resistant bottom plate and the central bracket are connected, to strengthen the structural load-bearing capacity, improve overall bending resistance, and prevent the circuit board from deforming under pressure. Both the pressure-resistant top plate and the pressure-resistant bottom plate are connected to reinforcing ribs, further enhancing their structural strength and improving their bending resistance to pressure and impact, thus protecting the circuit board. The circuit board structure achieves high strength, impact resistance, and pressure resistance, protecting the circuit board from damage and breakage, thereby protecting and extending the service life of the circuit board.
[0008] Preferably, the central support has a mounting screw hole, and both the pressure-resistant top plate and the pressure-resistant bottom plate are fitted with fixing screws, which are threaded into the mounting screw hole. The pressure-resistant top plate is connected to the central support via the fixing screw, ensuring a stable connection between them. Similarly, the pressure-resistant bottom plate is connected to the central support via the fixing screw, ensuring a stable connection between them. This ensures the stability and detachability of the entire structure, facilitating the installation and maintenance of the circuit board. This achieves the effect of improving the stability of connections between circuit board structures and facilitating easy assembly, disassembly, and maintenance.
[0009] Preferably, the mounting slot is equipped with a locking groove, and a locking block is connected to one side of the corner protector pad, which engages with the locking groove. The mounting slot connects to the locking block on one side of the corner protector pad via the locking groove, allowing for quick installation of the corner protector pad on the pressure-resistant top and bottom plates, as well as quick removal and replacement. This improves the efficiency of circuit board assembly and ease of maintenance.
[0010] Preferably, a buffer pad is provided on the other side of the corner protector. One side of the buffer pad is connected to the corner protector, and the other side of the buffer pad has a rounded corner shape. The buffer pad, made of rubber, is connected to the outer side of the corner protector. Its rounded corner shape and soft material buffer impact force and protect the circuit board, further improving the impact resistance of the circuit board structure.
[0011] Preferably, both the pressure-resistant top plate and the pressure-resistant bottom plate are provided with mounting screw holes two times. A fixing screw two is threaded into the mounting screw holes two times. One end of the fixing screw two is connected to a fixing block, which abuts against the circuit board body. The other end of the fixing screw two is connected to an anti-slip block. The pressure-resistant top plate rotates the fixing screw two on the mounting screw holes two times to abut against one side of the circuit board body, and the pressure-resistant bottom plate rotates the fixing screw two on the mounting screw holes two times to abut against the other side of the circuit board body. This fixes the circuit board body to the central support from both the top and bottom, allowing for vertical heat dissipation while ensuring stable installation. The anti-slip block facilitates rotation of the fixing screw two from the outside. This achieves the effect of improving the stability and ease of operation of the circuit board installation.
[0012] Preferably, the reinforcing rib has a triangular shape, with one end protruding from the central support. The positioning groove has a Y-shaped cross-section. One side of the triangular reinforcing rib connects to the central support, while the other side protrudes from the central support to engage with the positioning groove, forming a triangular support to increase strength. The Y-shaped cross-section of the positioning groove allows the reinforcing rib to be inserted into the groove during assembly. This achieves the effect of improving the circuit board's structural compressive strength and connection stability.
[0013] Preferably, the reinforcing ribs include upper ribs, of which several are provided. These upper ribs are connected to both the outer and inner surfaces of the pressure-resistant top plate and are evenly distributed. The upper ribs on the outer and inner surfaces of the pressure-resistant top plate are arranged in a cross-shaped pattern. The upper ribs are evenly connected to the outer and inner surfaces of the pressure-resistant top plate, and their crisscrossing and perpendicular arrangement enhances the impact and pressure resistance of the pressure-resistant top plate, thereby improving the overall pressure resistance of the circuit board structure.
[0014] Preferably, the reinforcing ribs include lower ribs, of which several are provided. These lower ribs are connected to both the outer and inner surfaces of the pressure-resistant base plate and are evenly distributed. The lower ribs on the outer and inner surfaces of the pressure-resistant base plate are arranged in a cross-shaped pattern. The lower ribs are evenly connected to the outer and inner surfaces of the pressure-resistant base plate, and their crisscrossing and perpendicular arrangement enhances the impact and pressure resistance of the pressure-resistant base plate. This achieves the effect of improving the overall pressure resistance of the circuit board structure.
[0015] The beneficial effects of this utility model are: the circuit board structure has high strength, impact resistance, and pressure resistance; it protects the circuit board from damage and breakage; it protects and extends the service life of the circuit board; and it improves the stability of the connection between structures and facilitates installation, removal, and maintenance.
