Flexible high-power RF line with joints
A tiltable RF joint for high power coaxial RF lines includes a first outer conductor with a first inner conductor centered therein and a second outer conductor with a second inner conductor centered therein. The first inner conductor that contains a joint socket is mechanically coupled to a joint ball of the second inner conductor and forms a socket-ball connection. The first inner conductor also contains a center contact surface that is shaped as a spherical segment and that is in contact with a center contact spring of the second inner conductor. Any one of the outer conductors has an outer conductor contact spring that is in contact with an outer conductor contact surface at the other outer conductor.
