[0029] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0030] Example 1

[0031] Please see Figures 1-3 As shown, this embodiment provides a flexible circuit board, including a flexible circuit board body 1. An adhesive film 7 is bonded and fixed to the bottom end of the flexible circuit board body 1 to increase the toughness of the flexible circuit board body 1. A set of protective components is provided between the flexible circuit board body 1 and the adhesive film 7 to protect the edges of the flexible circuit board body 1 to prevent damage to the edges during bending or folding.

[0032] To achieve a firm connection between the flexible circuit board body 1 and the adhesive film 7, in this embodiment, multiple adhesive strips 8 are provided between the adhesive film 7 and the flexible circuit board body 1. These adhesive strips 8 are uniformly adhered and fixed to the bottom end of the flexible circuit board body 1. The provision of adhesive strips 8 not only increases the stability of the connection, but also disperses stress to a certain extent, improving the fracture resistance of the flexible circuit board body.

[0033] Multiple second connecting slots 5 are also provided inside the flexible circuit board body 1. These second connecting slots 5 are used to install various components on the flexible circuit board body 1.

[0034] Example 2

[0035] Improvements based on Example 1: See Appendix Figure 1 -Appendix Figure 3 This embodiment further details the design of the protective component. The protective component includes a wrapping side film 2, which is fixed to the top of the flexible circuit board body 1 and bent towards the top of the flexible circuit board body 1, thus adhering and fixing it to the flexible circuit board body 1. In this way, the wrapping side film 2 can effectively wrap and protect the edges of the flexible circuit board body 1.

[0036] To further enhance the connection stability between the flexible circuit board body 1, the wrapping side film 2, and the adhesive film 7, a set of connecting components is also provided in this embodiment. The connecting components include multiple extension blocks 3, which are uniformly fixed to the wrapping side film 2. Each extension block 3 has a first connecting groove 4, which communicates with a second connecting groove 5 within the flexible circuit board body 1. Simultaneously, multiple third connecting grooves 6 are also formed within the adhesive film 7, which communicate with the second connecting grooves 5, enabling a tight connection between the flexible circuit board body 1, the wrapping side film 2, and the adhesive film 7 when the flexible circuit board body 1 is fixed.
