Abstract
Abstract A coaxial connector for a coaxial conductor, such as an antenna feeder, which can isolate one device from another along the length of the conductor, such as an antenna from a television receiver for avoiding electric shock. The connector includes a disc-shaped condenser and a circular condenser disposed around and coaxial with the disc-shaped condenser, central conductors and outer conductors of the coaxial conductor are connected through the disc-shaped condenser and the circular condenser respectively.
