Definitions

  • This invention relates to an improved coaxial connector construction
  • An RF coaxial line consists of an inner conduc-tor, which is usually round but not necessarily so, a surrounding, usually coaxial, dielectric member, which is primarily 4to provide electrical insulation but which almost always lis to provide mechanical support for the center conductor as well, and an outer conductor, which has aninner surface which forms the boundary of the RF transmission line.
  • the coaxial line then consists of three coaxial parts.
  • the coaxial line is in the form of a connector the means for mounting the connector is normally connected with the outer conductor and it is necessary to anchor the dielectric and the inner conductor to the outer conductor.
  • the coaxial line takes the form of a cable the three coaxial parts are firmly anchored by the frictional forces due to closeness of iit of these parts over a considerable length.
  • the dielectric is of a relatively smooth and frictionless material, such as Teflon, which, in a connector, does not frictionally grip the center conductor adequately to prevent axial movement -of the center conductor relative to the remainder of the connector kupon repeated engagement and disengagement with a mating connector; if the dielectric were not anchored, as by a combination of shoulders and snap rings, .it would be possible for the dielectric itself to shift relatively axially.
