Technical Field
[0001] The invention relates to a flexible circuit board, in particular to a single-sided static flexible circuit board. Background Art
[0002] The substrate of a single-sided flexible circuit board usually has good flexibility, electrical insulation, heat resistance and dimensional stability. Copper foil acts as a conductive layer and provides the required electrical connection. In addition, the mechanical strength of the flexible circuit board in a specific area can be improved by adding reinforcement materials (such as FR4, steel sheet or PI reinforcement) to meet different application requirements.
[0003] Adding reinforcement materials in specific areas is to improve the mechanical strength of these areas to prevent cracking or damage during use. Once the flexure position of the single-sided flexible circuit board does not occur at the reinforcement position, it is more likely to cause cracking or damage. Summary of the invention

[0006] On the basis of the above technical scheme, the static deflection reinforcement structure includes a rotating shaft, a sliding hole, a support column, an interface, a fixed block, a reinforcing material, and an adhesive. The rotating shaft is axially connected to each other for rotation, the sliding hole is radially opened at the side end of the rotating shaft, the support column is slidably connected to the rotating shaft through the sliding hole, the interface is alternately distributed at the front and rear ends of the support column, and the support column is connected to the bottom of the interface part through the interface, the fixed blocks are alternately distributed at the front and rear ends of the support column, the reinforcing material is fixed to the top of the fixed block, the adhesive is distributed at the top of the reinforcing material, and the reinforcing material is fixed to the bottom of the flexible substrate through the adhesive.
[0007] Based on the above technical solution, the interface component supports and reinforces the flexible substrate by rotating the support columns to bend the reinforcing material.
[0008] Compared with the prior art, the present invention has the following advantages: the present invention ensures that the deflection occurs at the reinforcement position by installing a static deflection reinforcement structure on a single-sided static flexible circuit board.

[0014] like Figures 1 to 3 As shown, a single-sided static flexible circuit board includes a flexible substrate 1, a circuit 2, a coating 3, an interface component 4, and a static flexural reinforcement structure 5. The circuit 2 is distributed on the top of the flexible substrate 1, the coating 3 is coated on the top of the flexible substrate 1, and the upper parts of the two interface components 4 are respectively connected to the front and rear ends of the circuit 2, and the static flexural reinforcement structure 5 is installed at the bottom of the front and rear two interface components 4.
[0015] The static deflection reinforcement structure 5 includes a rotating shaft 6, a sliding hole 7, a support column 8, an interface 9, a fixed block 10, a reinforcing material 11, and an adhesive 12. The rotating shaft 6 is axially connected to each other in rotation, the sliding hole 7 is radially opened at the side end of the rotating shaft 6, the supporting column 8 is slidably connected to the rotating shaft 6 through the sliding hole 7, the interface 9 is alternately distributed at the front and rear ends of the supporting column 8, and the supporting column 8 is connected to the bottom of the interface member 4 through the interface 9, the fixed block 10 is alternately distributed at the front and rear ends of the supporting column 8, the reinforcing material 11 is fixed to the top of the fixed block 10, the adhesive 12 is distributed at the top of the reinforcing material 11, and the reinforcing material 11 is fixed to the bottom of the flexible substrate 1 through the adhesive 12.
