Flexible printed circuit (FPC) board capable for preventing radio frequency interference

Abstract

The invention provides a flexible printed circuit (FPC) board capable for preventing radio frequency interference. The FPC board comprises an FPC substrate, wherein hollow plates are pasted at two sides of the top of the FPC substrate, an anti-interference layer is arranged at the top of the FPC substrate, fixed rods are fixedly arranged at two sides of inner walls of the hollow plates, the bottomof the fixed rod arranged at the right side is hinged with a rotation rod via a hinge piece, a torsional spring is fixedly arranged at one side of the rotation rod, a trapezoid block is fixedly arranged at the other side of the rotation rod, a sliding rod is welded with the bottom of the trapezoid block, a sliding rail is slidingly connected with the bottom of the sliding rod, clamping grooves are formed in two sides of the anti-interference layer, and one end of the sliding rod extends to the clamping grooves. In the FPC board capable of preventing the radio frequency interference, the interference of an external signal on the FPC substrate is prevented by arranging the anti-interference layer, so that the stability of the FPC substrate can be ensured; and by arranging the torsional spring and the sliding rod, the operation that the anti-interference layer is subsequently disassembled to maintain a circuit on the FPC substrate is facilitated.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to an FPC circuit board for preventing radio frequency interference. Background technique [0002] It is easy to cause signal interference due to external forces, that is, radio frequency interference, which makes its performance unstable. For example, when the FPC circuit board applied to the display screen, when radio frequency interference occurs, the flickering phenomenon will occur, making it unreliable. While the quality of the display screen cannot be guaranteed, it cannot satisfy the user's comfortable experience. For the FPC circuit boards used in various display screens, the structure of the relevant FPC circuit boards is improved. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a radio frequency interference-proof FPC circuit board, which solves the problems rai...
