Patent ID: 8531809

Claim:
A surge protector comprising: a first surge suppression assembly ( 1 ) comprising a base board ( 10 ), a first conductive layer ( 20 ) disposed on the base board ( 10 ), a second conductive layer ( 30 ) disposed on the base board ( 10 ) and spaced from the first conductive layer ( 20 ) wherein the first conductive layer ( 20 ) comprises an arm ( 21 ), an extension ( 22 ) distal to the arm ( 21 ) and having toothed edges, a substantially C-shaped member ( 23 ) projecting out of the extension ( 22 ) and having toothed edges, and a substantially circular member ( 24 ) with toothed edges formed at an open end of the extension ( 22 ) to be disposed at about center of the substantially C-shaped member ( 23 ); the second conductive layer ( 30 ) comprises an arm ( 31 ) including a terminal ( 311 ), an extension ( 32 ) being distal to the arm ( 31 ), a projecting first substantially C-shaped member ( 33 ) having toothed edges, and a second substantially C-shaped member ( 34 ) at an open end of the extension ( 32 ); and the first substantially C-shaped member ( 33 ), the substantially C-shaped member ( 23 ), the second substantially C-shaped member ( 34 ), and the substantially circular member ( 24 ) are arranged in a concentric, spaced fashion with two sets of two half-circular gaps ( 11 ) formed at positions spaced from both sides of the extension ( 22 ) respectively; and an overvoltage protection assembly ( 60 ) comprising an overvoltage protection member ( 61 ) interconnecting the arm ( 31 ) and the terminal ( 311 ); wherein the overvoltage protection assembly ( 60 ) is electrically connected to the first surge suppression assembly ( 1 ) via the arm ( 31 ); and wherein the overvoltage protection member ( 61 ) is implemented as a unitary member, a plurality of members connected in series, or a plurality of members connected in parallel.
