The invention belongs to the technical field of machine body lightning protection, and particularly relates to a conductive method and structure between a composite material movable cover and a machine body fixed structure, a conductive path is provided between a composite material radome and a machine body structure which are connected in a hinged mode, and a copper net and a diversion copper bar with a proper section size are laid in a composite material structural part. And a low-impedance path is designed between the movable component and the fixed component by utilizing the fastening piece, the anti-loose cup-shaped piece and the lapping wire. On the basis of not influencing radar work and not damaging the original appearance of a radome, the problem that conducting and shunting between a composite material movable component and a fixed structural component are difficult is solved, and meanwhile, a lightning protection device or measure adopted in the method has the capacity of corrosion resistance, vibration looseness prevention and repeated disassembly and assembly and replaceability; the method is high in application expansibility, can be widely applied to conductive paths of other composite material movable components and fixed components, and has great reference significance.
