Connector arrangement for coaxial cables

In a combination, a coaxial cable having a protective outer sheath, an outer conductor inwards of said outer sheath and an inner conductor inwards of said outer conductor, the coaxial cable having an end comprised of an endmost first portion along which said inner conductor is exposed, a second portion from which both said protective sheath and said outer conductor have been removed, a third portion from which said protective sheath has been removed, and a fourth portion from which said protective sheath has not been removed;

• a moisture-proof and radiation-impervious connector arrangement connected to said end of said coaxial cable and comprising a connector sleeve having one end surrounding and tightly holding said fourth portion of said cable and provided at its other end with an internal conical cavity surrounding said third portion of said cable, an additional one-piece connector unit including an axially extending portion surrounding said second portion of said cable and having a conically configurated end portion which is located slipped under said outer conductor along at least part of said third portion of said cable, said conically configurated end portion projecting into said conical cavity in said connector sleeve, and said outer conductor along at least said part of said third portion of said cable being outwardly deformed and widened and tightly wedged between the outer surface of said conically configurated end portion and the wall of said internal conical cavity all around the circumference of the wedged portion of said outer conductor, said conically configurated end portion, said wall of said internal conical cavity and the wedged portion of said outer conductor together forming a circumferentially complete annular seal, and wherein the material of said additional connector unit at the portion thereof in contact with said wedged part of said outer conductor is electrically conductive so that all around said circumferentially complete annular seal there exists a circumferentially complete annular zone of electrical contact between the wedged portion of said outer conductor and ssaid conically configurated end portion;
• and means connecting together said connector sleeve and said additional connector unit, wherein said connector sleeve is comprised of a collar portion which constitutes said one end of said connector sleeve and which surrounds and tightly holds said protective outer sheath and an internal shoulder separating the interior of said collar portion from said internal conical cavity, and wherein the end face of said protective sheath at the boundary of said fourth portion of said cable abuts against said shoulder to be thereby properly positioned within said connector sleeve, wherein said connector sleeve at the end thereof provided with said internal conical cavity is further provided with an annular outwardly projecting abutment portion, and wherein said means comprises a connector nut having one end provided with an inwardly projecting ridge-like portion which abuts against said outwardly projecting abutment portion and another end in screwthreaded engagement with said additional connector unit, said screwthreaded engagement being such that when said connector nut is tightened said inwardly projecting ridge-like portion presses against said outwardly projecting abutment portion thereby drawing said connector sleeve and said additional connector unit tightly together, wherein said additional connector unit is an inset which is partially received within said connector nut and partially received within said internal conical cavity, and wherein said cable along said second portion thereof has a predetermined outer diameter, and wherein said inset has an internal bore having a diameter substantially equal to said predetermined outer diameter so as to surround and firmly hold said second portion of said cable end, and wherein said inset at the end thereof facing away from said internal conical cavity is further comprised of an extension provided with an external screwthread forconnecting said inset to another component, wherein said connector arrangement further includes a clamping sleeve surrounding and clamping said fourth portion of said cable end, said clamping sleeve having one end which adjoins said end face of said protective sheath and together with the latter abuts against said shoulder, to thereby be properly positioned within said connector sleeve, and wherein said clamping sleeve is provided at its other end with an external screwthread mating with an internal screwthread provided on the adjoining interior wall of said collar portion, wherein said clamping sleeve is provided with a plurality of annular inwardly projecting radial ridges.
