[0001] The utility model relates to a circuit board, in particular to a circuit board with good protection effect. Background Art

[0002] A circuit board, also known as a printed circuit board, is a core component in electronic devices for connecting and supporting electronic components. It replaces traditional complex wire connections through pre-designed conductive lines to achieve electrical interconnection between components.

[0003] Even with anti-static bags for protection, existing circuit boards are prone to being bumped during transportation, resulting in damage to electrical components on the circuit board. To address this problem, we propose a circuit board with good protection effect. Summary of the Utility Model

A protection cavity is formed inside the protection cover, and the electrical components on the circuit board body are located in the protection cavity;

[0006] The upper side of the protection cavity is detachably connected with a sealing top plate assembly;

[0007] A wiring port is arranged on the circuit board body.

[0008] The further setting of the utility model is: The protection cover includes a lower seat and an upper cover. A plurality of through holes are formed inside the lower seat, and bolts are arranged in each of the through holes. Each bolt is threadedly connected to the base;

[0029] Embodiment:

[0030] As Figures 1 to 4 shown, a circuit board with good protection effect includes a circuit board body 11. A base 12 is fixedly provided on the lower side of the circuit board body 11. A plurality of mounting holes are vertically penetrated through the upper side surface of the base 12, so as to facilitate technicians to assemble the circuit board with good protection effect into an electrical device. A protective cover 13 is installed on the base 12. A protection cavity 14 with an upward opening is formed in the protective cover 13. A protection net 31 is fixedly provided on the upper side of the protection cavity 14. Electrical components (not shown in the figure) on the circuit board body 11 are all covered in the protection cavity 14. The protection net 31 protects the circuit board with good protection effect after installation, so that it does not interfere with the connection wires of other electrical components.

[0031] Furthermore, the protective cover 13 includes a lower seat 16 and an upper cover 17. A plurality of through holes 18 are formed in the lower seat 16. Bolts 19 are respectively arranged in the through holes 18, and each bolt 19 is threadedly connected to the base 12 to fix the lower seat 16.

[0032] A lifting ring groove 20 is formed in the lower side surface of the upper cover 17. A support ring sleeve 21 is fixedly arranged on the upper side surface of the lower seat 16. The upper cover 17 is slidably connected to the support ring sleeve 21 up and down through the lifting ring groove 20. A plurality of springs 22 are connected between the upper side surface of the support ring sleeve 21 and the bottom wall of the lifting ring groove 20. Rubber rings 23 are fixedly arranged at the edges of the upper side surface of the support ring sleeve 21. The rubber rings 23 act as dampers. During transportation, when the upper cover 17 is squeezed, it will move downward and squeeze the springs 22. Through the cooperation of the springs 22 and the rubber rings 23, a buffering and shock-absorbing effect is achieved, so as to protect the electrical components on the circuit board body 11, and further ensure the stability of the upper cover 17 and the support ring sleeve 21.

[0033] A wiring port 32 is arranged at the lower edge of one side side wall of the circuit board body 11. A wiring hole 34 corresponding to the wiring port 32 is formed at the lower edge of the support ring sleeve 21 on the same side. A sealing sticker 36 is pasted on the outer side of the wiring hole 34 to ensure that dust and impurities will not enter the wiring hole 34 during transportation. When installing the circuit board with good protection effect, the technician tears off the sealing sticker 36, and inserts the wiring terminal (not shown in the figure) of other equipment into the wiring port 32 through the wiring hole 34. Limit plates 33 are fixedly arranged on the left and right outer side walls of the support ring sleeve 21. The downward stroke of the upper cover 17 is limited through the limit plates 33 to prevent the lower side surface of the upper cover 17 from interfering with the wiring terminal.

[0034] Furthermore, since the protection net 31 is not a closed structure, dust is likely to enter the protection cavity 14 through the protection net 31 during transportation. In order to protect the electrical components on the circuit board body 11, sliding grooves 24 are respectively formed in the left and right side walls on the upper side of the protection cavity 14. A front sliding plate 25 and a rear sliding plate 26 are symmetrically slidably connected back and forth in the sliding grooves 24 on the left and right sides together. A permanent magnet 27 is fixedly arranged on the rear side surface of the front sliding plate 25. A slot 28 is formed in the front side surface of the rear sliding plate 26. A metal sheet 29 is fixedly arranged on the bottom wall of the slot 28. During the transportation of the circuit board with good protection effect, the permanent magnet 27 is inserted into the slot 28 and magnetically adsorbed on the metal sheet 29, so that the protection cavity 14 is in a closed state, so as to prevent impurities and dust from entering the protection cavity 14 and adhering to the surface of the electrical components, causing faults of the electrical components, and further achieving the purpose of protecting the electrical components;

[0035] After installing the circuit board with good protection effect on the installation platform, in order to ensure the heat dissipation efficiency of the electrical components, the technician can pull out the front slide plate 25 and the rear slide plate 26 from the sliding groove 24, and dragging handles 30 are fixedly arranged on the front side surface of the front slide plate 25 and the rear side surface of the rear slide plate 26, so as to facilitate the technician to drag the front slide plate 25 and the rear slide plate 26.

[0036] Moreover, the left and right side walls of the circuit board body 11 are abutted against the lower left and right side walls of the protection cavity 14, and a plurality of heat dissipation fins 35 are fixedly arranged on the left and right outer side walls of the upper cover 17, so as to further improve the heat dissipation efficiency of the circuit board with good protection effect. It should be noted here that both the upper cover 17 and the lower seat 16 are made of aluminum matrix composite materials, which have excellent thermal conductivity and good insulation performance, so as to ensure the normal operation of the circuit board body 11.

[0037] At the same time, it should be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection scope of the present invention.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
