[0002] Circuit board, also known as printed circuit board or printed circuit board, PCB in English, is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Before the emergence of circuit boards, the interconnection between electronic components was completed by direct connection of wires. Nowadays, wires are only used for experimental applications in laboratories, and circuit boards have occupied an absolute dominant position in the electronics industry.

[0003] Circuit boards are prone to dust accumulation during use, which can easily cause short circuit faults and other problems. Conventional circuit boards are usually coated with resin or film on the surface to achieve dust protection, but this method will cause the circuit board to be sealed and thicker, making it difficult to dissipate the heat generated during the operation of the circuit board, greatly affecting the normal operation and service life of the circuit board.

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] like Figures 1 to 5As shown, the utility model provides a dustproof and durable circuit board 100, which includes an assembly shell 10, two groups of dustproof components 20, two groups of limiting components 30 and a circuit board body 40. The assembly shell 10 is designed as a frame structure that penetrates from top to bottom. The two groups of dustproof components 20 are both engaged in the assembly shell 10 and are symmetrically arranged from top to bottom. The two groups of limiting components 30 are installed on both sides of the upper end of the assembly shell 10 and limit the dustproof components 20 on the upper side. The circuit board body 40 is clamped between the two groups of dustproof components 20.

[0019] The dustproof assembly 20 includes a clamping frame 21, a plurality of bearing rods 22 and a plurality of rotating leaves 23. The clamping frame 21 is provided with a plurality of heat dissipation windows 211 extending vertically therethrough. One end of the plurality of bearing rods 22 is fixedly mounted on the clamping frame 21, and the other end is pressed against the circuit board body 40. The plurality of rotating leaves 23 are respectively engaged in the heat dissipation windows 211 and can be adjusted and rotated synchronously. Specifically, in the present embodiment, the plurality of bearing rods 22 are all designed with elastic telescopic structures. The sides of the plurality of rotating leaves 23 and the heat dissipation windows 211 are all designed with inclined structures.

[0020] When the circuit board is powered on, the rotating leaf 23 can be adjusted to open the dustproof assembly 20, thereby ensuring the heat exchange efficiency between the circuit board and the outside world; and when the circuit board is powered off and idle, the rotating leaf 23 can be readjusted to close the dustproof assembly 20, thereby isolating the dust and dirt from the outside from entering the circuit board and affecting the use of the circuit board. The elastic and telescopic bearing rod 22 can play a certain buffering role and enhance the circuit board's ability to resist shock and bump, while the edge of the rotating leaf 23 with an inclined structure is more convenient for its adjustment and rotation.

[0021] The dustproof assembly 20 further includes a plurality of breathable dustproof nets 24, the two ends of which are respectively engaged with one side of the two rotating leaf pieces 23 or one side of the rotating leaf piece 23 and one side of the clamping frame 21, and the breathable dustproof nets 24 are movable and retractable. The upper dustproof assembly 20 further includes two lifting handles 25, which are mounted on the upper end of the clamping frame 21. The movable and retractable breathable dustproof nets 24 can further enhance the isolation effect of the dustproof assembly 20, and the lifting handles 25 facilitate the removal of the upper dustproof assembly 20 from the assembly housing 10, so as to perform maintenance and cleaning operations on the circuit board body 40 inside.

[0022] The position limiting assembly 30 includes a lifting seat 31, a rotating rod 32, a position limiting plate 33 and two sets of adjusting screw rods 34. Lifting slots 11 are respectively provided inside the two sides of the assembly housing 10. The lifting seat 31 is engaged in the lifting slots 11 and can be lifted and lowered movably. One end of the rotating rod 32 is axially connected to the lifting seat 31 and can be rotatable, and the other end extends to the inner side of the assembly housing 10. The position limiting plate 33 is fixedly mounted on the other end of the rotating rod 32. The two adjusting screw rods 34 are inserted into the lifting slots 11 from top to bottom and are inserted into the two ends of the lifting seat 31.

[0023] When the dustproof assembly 20 needs to be locked, the rotating rod 32 and the limiting plate 33 need only be rotated to keep them horizontal, and then the adjusting screw rod 34 needs to be rotated to lower the lifting seat 31 so that the limiting plate 33 can be pressed against the upper surface of the dustproof assembly 20. When the locking needs to be released, the adjusting screw rod 34 needs only to be rotated again to raise the lifting seat 31, and then the rotating rod 32 and the limiting plate 33 need to be pulled to keep them vertical.

[0024] To sum up, the beneficial effects of the dustproof and durable circuit board 100 of the utility model are: by designing an adjustable opening and closing dustproof component 20, the circuit board is protected from dust, so that the circuit board can be isolated from external dust and dirt when idle, and can ensure efficient heat dissipation of the circuit board during operation, thereby maximizing the service life of the circuit board; the movable limit component 30 is designed to engage and limit the circuit board body 40, so that the circuit board is easier to assemble and form, and can adapt to various thickness specifications; the utility model is highly practical and has a strong promotional significance.

[0025] The above-mentioned embodiment only expresses one implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
