Description

Technical Field

[0001] This application relates to the field of printed circuit board technology, and more specifically to a ruggedized printed circuit board. Background Technology

[0002] Circuit boards are indispensable basic components in modern electronic devices, widely used in computers, communication equipment, home appliances, industrial control, and other fields. The main function of a circuit board is to provide circuit connections and support, assembling various electronic components according to a predetermined circuit design to achieve signal transmission and power distribution. Depending on the materials and applications, circuit boards come in a wide variety of types, including ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, PCBs (printed circuit boards), aluminum-based boards, high-frequency boards, thick copper boards, impedance boards, and ultra-thin circuit boards. These circuit boards, with their high efficiency and reliability, have driven the miniaturization and functional optimization of electronic devices.

[0003] Despite the diversity and powerful functions of circuit boards, existing circuit boards still face certain technical challenges in practical use. Because the main body of a circuit board is typically made of relatively thin material, its overall strength is limited. When subjected to external forces, the circuit board is prone to bending, deformation, or even breakage. This structural fragility can damage the internal circuitry, leading to short circuits, open circuits, and other problems, causing the device to malfunction. Furthermore, in complex application scenarios, such as high-vibration and high-impact environments, the reliability of traditional circuit boards further decreases, affecting the stability and lifespan of electronic devices.

[0004] To address the aforementioned issues, existing technologies have proposed several improvements, such as increasing the circuit board thickness and using higher-strength substrates to enhance its mechanical strength. However, these methods often increase material costs and processing difficulties, limiting their application in mass production. Therefore, there is an urgent need for a structurally optimized and cost-effective ruggedized printed circuit board that can significantly improve its mechanical strength and impact resistance while maintaining excellent electrical performance, thus meeting the demands of various complex environments. Utility Model Content

[0006] According to one aspect of this application, a ruggedized printed circuit board includes a circuit board body, protective components, and reinforcing components. Protective components are installed on the upper and lower sides of the circuit board body. Each protective component includes an upper protective plate and a lower protective plate. The upper and lower protective plates are fixedly installed on the upper and lower sides of the circuit board body, respectively, with a gap between the upper and lower protective plates and the circuit board. Reinforcing components are installed on the outer surfaces of both the upper and lower protective plates. Each reinforcing component includes a first reinforcing component and a second reinforcing component. The first reinforcing component is fixedly installed on both lateral sides of the outer surfaces of the upper and lower protective plates, and the second reinforcing component is fixedly installed on both longitudinal sides of the outer surfaces of the upper and lower protective plates.

[0007] Preferably, a plurality of insertion holes are evenly provided around the perimeter of the circuit board body, and a connecting hole is provided on the upper protective plate and the lower protective plate corresponding to each insertion hole. A support post is fixedly inserted into each insertion hole, and the upper and lower ends of each support post are fixedly connected to the upper protective plate and the lower protective plate respectively through the connecting hole.

[0008] Preferably, the first reinforcing component includes a first mounting plate, a transverse reinforcing rod, and a first reinforcing double nut. The first mounting plate is fixedly installed on both sides of the outer surface of the upper and lower protective plates, perpendicular to both ends. Each first mounting plate has a first mounting opening slot. The two ends of the transverse reinforcing rod are placed on the first mounting plate through the first mounting opening slot. The two ends of the transverse reinforcing rod are threaded with the first reinforcing double nut. The first reinforcing double nut is located on both sides of the first mounting plate. The transverse reinforcing rod is fixedly connected to the first mounting plate through the first reinforcing double nut. The transverse reinforcing rod reinforces the transverse side of the circuit board body.

[0009] Preferably, the second reinforcement component includes a second mounting plate, a T-shaped reinforcing rod, and a second reinforcing double nut. The second mounting plate is vertically fixed at both ends of the longitudinal side of the outer surface of the upper and lower protective plates, and also vertically fixed at the middle of the other side. Each second mounting plate has a second mounting opening slot. The three ends of the T-shaped reinforcing rod are placed on the second mounting plate through the second mounting opening slot. The three ends of the T-shaped reinforcing rod are threaded with a second reinforcing double nut. The second reinforcing double nut is located on both sides of the second mounting plate. The T-shaped reinforcing rod is fixedly connected to the second mounting plate through the second reinforcing double nut, and the T-shaped reinforcing rod reinforces both the longitudinal side of the circuit board body and the transverse middle of the circuit board body.

[0010] Preferably, a plurality of heat dissipation grooves are evenly spaced on the upper protective plate located above the components of the circuit board body.

[0011] The advantages of this application compared with the prior art are as follows: This application provides a reinforced printed circuit board, which, through protective components provided on the upper and lower sides of the circuit board body and reinforcement components provided on the protective components, the protective components include an upper protective plate and a lower protective plate, which can form an integral part with the upper and lower surfaces of the circuit board body through support columns. The reinforcement components include a first reinforcement component and a second reinforcement component. The first reinforcement component can strengthen the lateral side structure of the upper and lower protective plates, and the second reinforcement component can strengthen the longitudinal side and diagonal structure of the upper and lower protective plates. This can enhance the overall compressive strength of the circuit board body, prevent the circuit board body from bending under the action of external force during use, and prevent the circuit board body from being unable to be used normally, thereby improving the overall service life and facilitating operation.

Multiple heat dissipation slots 9 are evenly spaced on the upper protective plate 2, located above the components of the circuit board body 1. The design of the heat dissipation slots 9 facilitates heat dissipation of the circuit board body 1 during use. Specifically, multiple insertion holes 6 are evenly spaced along the perimeter of the circuit board body 1, with corresponding positions for each insertion hole 6 on the upper protective plate 2 and lower protective plate 3. Each of the mounting holes 6 has a connecting hole 7, and a support column 8 is fixedly inserted into each hole 6.

Specifically, the first reinforcing member 4 includes a first mounting plate 41, a transverse reinforcing rod 42 and a first reinforcing double nut 43. The transverse side edges of the outer surfaces of the upper protective plate 2 and the lower protective plate 3 are fixedly installed on the longitudinal side edges. A first mounting plate 41 is fixed horizontally along both sides and vertically at both ends. Each first mounting plate 41 has a first mounting opening slot. The two ends of the horizontal reinforcing rod 42 are placed on the first mounting plate 41 through the first mounting opening slot.

The horizontal reinforcing rod 42 is fixedly connected to the first mounting plate 41 through the first reinforcing double nuts 43. The horizontal reinforcing rod 42 reinforces the horizontal side of the circuit board body 1. The second reinforcing component 5 includes a second mounting plate 51, a T-shaped reinforcing rod 52, and a second reinforcing double nut 53. The longitudinal... A second mounting plate 51 is fixed vertically at both ends of the circuit board body 1 along its longitudinal direction and at the middle of the other side. Each second mounting plate 51 has a second mounting opening slot.
