Shielded banana plug with double shroud and input receptacle

摘要

A shielded banana plug attached to one end of a test lead is suitable for connection to a corresponding input receptacle in an instrument. The plug includes an inner conductor having an first nonconductive shroud which is concentric with and spaced apart from the inner conductor. The shroud extends beyond the tip of the inner conductor. A conductive shield is concentric with and outside the first nonconductive shroud and is recessed from the end of the shroud. A nonconductive outer shroud is spaced apart from and concentric with the shield and extends beyond the tip of the inner conductor. An input receptacle suitable for mating with the shielded banana plug includes an conductive inner sleeve for receiving the inner conductor, a nonconductive shroud that is concentric with and outside the inner sleeve and which extends beyond the inner sleeve, and a conductive outer sleeve for receiving the conductive shield. The input receptacle is also suitable for mating with a conventional, nonshielded banana plug.
