Almost every electronic device, from small items like watches and calculators to large systems like computers, communication devices, and military weaponry, utilizes PCBs to enable electrical interconnection between integrated circuits and other electronic components. A PCB consists of an insulating substrate, connecting wires, and solder pads for mounting and soldering electronic components, serving the dual purpose of conducting circuitry and providing insulation. It replaces complex wiring, enabling electrical connections between components in a circuit. This simplifies assembly and soldering, reduces the amount of wiring work required by traditional methods, significantly lessening the workload for workers; it also reduces overall size, lowers product costs, and improves the quality and reliability of electronic equipment.

[0003] Existing composite circuit boards are prone to damage to some electrical components due to external forces during use. This is mainly because the outer shell of the circuit board is mostly made of plastic. Plastic shells have a certain degree of toughness, and when the shell is subjected to external forces, it will deform and compress the electrical components, which will make the electrical components easy to be damaged. Utility Model Content

[0004] The purpose of this invention is to provide a composite PCB circuit board to solve the problems mentioned in the background art.

[0006] Preferably, the protective component includes a gate-shaped protective frame, and one outer wall of the protective frame has multiple equally spaced circular openings, and the protective rod is inserted into the inner wall of the circular opening.

[0007] Preferably, the protective frame has limit grooves on opposite outer walls, and two symmetrically arranged rubber pads are bonded to the bottom outer wall of the protective frame.

[0008] Preferably, the installation mechanism includes a mounting base fixedly connected to the plate body, and the top outer wall of the mounting base has two symmetrically arranged rectangular slots, and the protective frame is inserted into the inner wall of the two rectangular slots.

[0009] Preferably, the mounting base has an internal mounting cavity, and the inner walls on both sides of the mounting cavity have openings that communicate with the rectangular groove. The inner walls of the two openings are slidably connected to limit seats, and the specifications of the limit seats match the specifications of the limit groove. The outer walls on opposite sides of the two limit seats are fixedly connected to sliding seats.

[0010] Preferably, two symmetrically arranged fixing rods are fixedly connected to the inner walls of both sides of the mounting cavity, and springs are sleeved on the outer walls of the four fixing rods. The two sliding seats are slidably connected to the outer walls of the four fixing rods respectively. A driving disk is rotatably connected to one inner wall of the mounting cavity, and two connecting plates are eccentrically rotatably connected to one outer wall of the driving disk. One end of the two connecting plates is rotatably connected to the two sliding seats respectively. A rotating column is rotatably connected to one outer wall of the mounting seat, and the drive shaft of the rotating column is fixedly connected to the driving disk.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting multiple protective rods on the circuit board, the protective rods facilitate the protection of electrical components on the circuit board; and by setting an installation mechanism on the circuit board, the protective frame can be quickly disassembled. The protective rods are installed on the protective frame, which facilitates the maintenance or replacement of the protective rods in the future, thus solving the problem that electrical components on the existing circuit board are easily damaged by squeezing.

[0017] 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.

[0018] This utility model provides a technical solution:

[0019] Please see Figures 1-4 The figure shows a composite PCB circuit board, including a board body 1. Two symmetrically arranged mounting mechanisms 2 are installed on the top outer wall of the board body 1, and protective components 3 are connected to both mounting mechanisms 2. Multiple protective rods 4 are installed between the two protective components 3. The protective rods 4 have a T-shaped cross-section, and one end of the protective rods 4 has a through hole. The inner wall of the through hole is engaged with a limit pin.

[0020] In this embodiment, by installing two mounting mechanisms 2 on both sides of the top of the circuit board, the mounting mechanism 2 facilitates the quick assembly and disassembly of the two protective components 3. The two protective components 3 facilitate the support of the protective rod 4. The combination of multiple protective rods 4 facilitates the protection of electrical components on the circuit board, preventing the electrical components on the circuit board from being squeezed when the circuit board shell is deformed. The limiting pin on the protective rod 4 ensures that it is stably connected to the protective component 3.

[0021] Please see Figures 1-3 The protective component 3 shown in the figure includes a gate-shaped protective frame 8, and a number of equally spaced circular openings are provided on one side of the outer wall of the protective frame 8. The protective rod 4 is inserted into the inner wall of the circular opening. Limiting grooves 9 are provided on the opposite side of the outer wall of the protective frame 8. Two symmetrically arranged rubber pads 10 are adhered to the bottom outer wall of the protective frame 8.

[0022] In this embodiment, the round opening on the protective frame 8 facilitates the passage of the protective rod 4. Two protective frames 8 cooperate with the round opening to fix the protective rod 4 above the electrical components in the circuit board. The cooperation between multiple protective rods 4 facilitates the protection of the electrical components. When the outer shell is squeezed and deformed, the protective rod 4 is squeezed directly, avoiding the deformation of the outer shell from directly squeezing the electrical components. The opening of the limiting groove 9 facilitates the installation of the auxiliary protective frame 8 and ensures the stability of the protective frame 8.

[0023] Please see Figures 2-4The installation mechanism 2 shown in the figure includes a mounting base 5 fixedly connected to the plate body 1. Two symmetrically arranged rectangular slots 7 are formed on the top outer wall of the mounting base 5. A protective frame 8 is inserted into the inner wall of the two rectangular slots 7. An installation cavity 11 is formed inside the mounting base 5, and openings communicating with the rectangular slots 7 are formed on both sides of the inner wall of the installation cavity 11. Limit seats 17 are slidably connected to the inner walls of both openings, and the specifications of the limit seats 17 match the specifications of the limit slots 9. Sliding seats 16 are fixedly connected to the outer walls of opposite sides of the two limit seats 17. The installation cavity 11... Two symmetrically arranged fixing rods 12 are fixedly connected to the inner walls of both sides of the mounting cavity 11, and springs 13 are sleeved on the outer walls of the four fixing rods 12. Two sliding seats 16 are slidably connected to the outer walls of the four fixing rods 12 respectively. A drive disk 14 is rotatably connected to one inner wall of the mounting cavity 11, and two connecting plates 15 are eccentrically rotatably connected to one outer wall of the drive disk 14. One end of the two connecting plates 15 is rotatably connected to the two sliding seats 16 respectively. A rotating column 6 is rotatably connected to one outer wall of the mounting base 5, and the drive shaft of the rotating column 6 is fixedly connected to the drive disk 14.

[0024] In this embodiment, the two rectangular slots 7 on the mounting base 5 facilitate the insertion of the protective frame 8. The rubber pad 10 at the bottom of the protective frame 8 reduces wear between the bottom of the protective frame 8 and the rectangular slots 7. When the protective frame 8 is inserted into the rectangular slots 7, the limiting seat 17 is inserted into the limiting slot 9. The spring 13 drives the limiting seat 17 to be stably inserted into the limiting slot 9, effectively preventing the protective frame 8 from detaching from the mounting base 5. When disassembling the protective frame 8, the rotating column 6 is manually rotated. The rotation of the rotating column 6 drives the driving disk 14 to rotate. When the driving disk 14 rotates clockwise, it cooperates with the connecting plate 15 to pull the two sliding seats 16 to move towards each other. When the two sliding seats 16 move towards each other, they drive the two limiting seats 17 to disengage from the limiting slots 9, thereby unlocking the protective frame 8. When the two sliding seats 16 move towards each other, they compress the spring 13 on the fixing rod 12. When the rotating column 6 is released, the spring 13 resets and drives the limiting seats 17 to extend.
