This invention relates to a kind of folded and combined signal wires including a first wire and a second wire connected by a first connecting section and a second connecting section, a first connector is matched at the first end of the first wire and a second connector is matched at the second end of the first wire or the second end of the second wire, therefore, the first and second wires and signal lines distributed on the connecting sections connect the two connectors in circuit, and a foldable wire is formed in either of the two connectors so as to force the second wire to be rigged to the first wire along the foldable line to form a foldable line so that the second wire can be rigged to the first one along the foldable line, and the two wires are in single face plate, double face plate, multi-layer plate or a multi-face plate and a pile-up region is included in the two wires.
