Patent ID: 7782588

Claim:
A series surge suppression structure, comprising: a circuit board, a grounding line and a plurality of galvanization circuits being disposed thereon, a multilayer surge absorption unit being disposed in series on said ground line and said plurality of galvanization circuits, said each galvanization circuit being formed by connecting a plurality of chokes thereon together in series, said each surge absorption unit being constituted by a pair of parallel chokes and a layered surge suppression element connected between one end of said either choke and said ground line; a power connection terminal, positioned on one side of said circuit board and electrically connected to a final end of said multilayer surge absorption unit; and a protection terminal, positioned on another side of the circuit board, and electrically connected to a final end of another side of said multilayer surge absorption unit; whereby, said protection terminal is used to connect a communication circuit or an electric facilities and said power connection terminal is used to connect to an external wire to form a multilayer surge absorption protection by means of series connection.
