DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] Reference Figures 1-3 An embodiment provided by the present application: a flexible circuit board with a protection structure, comprising a support plate one 1, the support plate one 1 is provided with a support plate two 2 on one side, the support plate two 2 is fixedly connected with a fixed block 6 on the top, the fixed block 6 is slidably connected with a limiting plate 7 inside, the limiting plate 7 is fixedly connected with a clamping block 8 on one side, the fixed block 6 is provided with a telescopic rod 9 inside, the telescopic rod 9 is provided with a reset assembly on the outer wall, one end of the telescopic rod 9 is fixedly connected to the other side of the limiting plate 7, the other end of the telescopic rod 9 is fixedly connected to the inside of the fixed block 6, the support plate two 2 is provided with a flexible circuit board body 3 on the top, the reset assembly comprises a spring 10, the spring 10 is sleeved on the outer wall of the telescopic rod 9 inside, one end of the spring 10 is fixedly connected to the other side of the limiting plate 7, the other end of the spring 10 is fixedly connected to the inside of the fixed block 6, the support plate two 2 is fixedly connected with a connecting block 5 on both sides, the connecting block 5 is rotatably connected with a rotating shaft 4 inside, the rotating shaft 4 is rotatably connected to the inside of the support plate one 1;

[0028] Specifically, multiple support plate two 2 are combined between the two support plate one 1. The support plate two 2 provides stable support for the entire structure, and are connected to each other through the rotating shaft 4 to form a whole. This connection method not only allows the support plate two 2 to be easily adjusted, but also ensures the stability and durability of the entire structure. Then, the flexible circuit board body 3 is placed on the support plate two 2. In order to ensure the accuracy and stability of the flexible circuit board body 3, the clamping block 8 is used to limit it. The clamping block 8 is designed ingeniously and practically, which is limited inside the fixed block 6 through the limiting plate 7, so as to ensure the accurate position of the clamping block 8. Instead of being simply fixed in position, the clamping block 8 is supported by the tension of the spring 10. This design allows the clamping block 8 to have a certain elasticity when subjected to external force, which can not only firmly fix the flexible circuit board body 3, but also can be adjusted and buffered when necessary, effectively preventing the risk of the flexible circuit board body 3 falling off the support plate two 2 due to accidents.

[0029] Referring to Figure 1 and Figure 4 , the flexible circuit board body 3 is internally provided with a substrate layer 11, the top of the substrate layer 11 is fixedly connected with a copper foil layer 12, the top of the copper foil layer 12 is fixedly connected with a cover layer 13, the top of the cover layer 13 is fixedly connected with a shielding layer 14, and the flexible circuit board body 3 is composed of the substrate layer 11, the copper foil layer 12, the cover layer 13 and the shielding layer 14;

[0030] Specifically, the flexible circuit board body 3 is composed of the substrate layer 11, the copper foil layer 12, the cover layer 13 and the shielding layer 14. Among them, the substrate layer 11 is made of polyimide, which has very high flexibility and durability, so that the flexible circuit board can maintain stable performance in various environments and conditions. The copper foil layer 12, as the conductor part of the circuit board, undertakes the important task of electrical connection and signal transmission. It is composed of foil and can provide good electrical conductivity to ensure the rapid transmission of electronic signals within the board. The cover layer 13 is another important part, made of polyimide film. Its main role is to protect the copper foil layer 12 from mechanical damage, ensuring that the circuit board has a longer service life in actual application. The presence of the cover layer 13 also makes the flexible circuit board have better wear resistance during deformation such as bending and folding. In addition, the flexible circuit board is also provided with a shielding layer 14 composed of a conductive coating. The main function of the shielding layer 14 is to shield external electromagnetic fields to protect internal circuits and signals from interference. This is particularly important today as electronic devices are becoming increasingly miniaturized and multifunctional. Through the action of the shielding layer 14, the flexible circuit board can still work stably in a highly electromagnetic interference environment, improving its adaptability in complex scenarios.

[0031] Working principle: when using the flexible circuit board with protection structure, first, the flexible circuit board body 3 is composed of the substrate layer 11, the copper foil layer 12, the cover layer 13 and the shielding layer 14, the substrate layer 11 is made of polyimide and has good flexibility and durability, the copper foil layer 12 is composed of foil and provides electrical connection and signal transmission, the cover layer 13 is polyimide film and protects the copper foil layer 12 from mechanical damage, and the shielding layer 14 is composed of a conductive coating and can shield external electromagnetic fields to protect internal circuits and signals from interference, then a plurality of support plates two 2 are combined between two support plates one 1, the support plates two 2 are connected and combined by the shafts 4, then the flexible circuit board body 3 is limited on the support plates two 2 by the clamping blocks 8, the clamping blocks 8 are limited in the fixed blocks 6 by the limiting plates 7, and the clamping blocks 8 are supported by the tension of the springs 10, so that the clamping blocks 8 can limit the flexible circuit board body 3 and are not easy to fall off the support plates two 2.

[0032] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
