Patent ID: 7196893

Claim:
Anti-interference filter and lightning arrester device in a coaxial line for the transmission of high-frequency signals, comprising a housing ( 1 ) with two connectors ( 2 , 3 ), the housing ( 1 ) forming an outer conductor connected to ground, an inner conductor ( 4 ) carried through the housing ( 1 ), a connection ( 5 ) between inner conductor ( 4 ) and housing ( 1 ) for the diverting of overvoltages and two gas capsule diverters ( 6 , 7 ) in the connection ( 5 ) between inner conductor ( 4 ) and housing ( 1 ), characterized in that in the connection ( 5 ) between inner conductor( 4 ) and housing ( 1 ) the two gas capsule diverters ( 6 , 7 ) are interconnected in series, between the two gas capsule diverters ( 6 , 7 ) a contact point ( 8 ) is disposed and a switching configuration ( 9 ) with an interrupter element ( 10 ) for the interruption of a current flowing across the gas capsule diverters ( 6 , 7 ) is disposed between the contact point ( 8 ) and the housing ( 1 ) or ground, the switching configuration ( 9 ) comprising a resistance element ( 11 ) connected with the contact point ( 8 ), a voltage-limiting element ( 12 ) being connected in series with the resistance element ( 11 ), and a coil ( 13 ) of a switching relay also being connected in series with the resistance element ( 11 ), the voltage-limiting element ( 12 ) and the coil 13 of the switching relay being connected in parallel.
