Connector for coaxial transmission lines

Claim 1

A connector for transmission lines of the coaxial cable type, the combination comprising a body member, a contact pin mounted in said body member at one end thereof, said pin being provided with a centrally positioned cavity and a shoulder portion at its inner end, and a thin flexible disk of conductive material adapted to be positioned against said shoulder portion, said disk having a small central opening and a plurality of slits extending radially outwardly from said opening whereby the disk can be bowed toward said cavity to enlarge the opening for receiving the center conductor of a coaxial transmission line and then flexes back securely to clamp said center conductor and provide electrical connection therewith, said body member is provided with an internally threaded opening at the end thereof opposite to said contact pin and with an inwardly extending shoulder located intermediate its ends, a metallic eyeletlike member comprising a thin-walled sleeve having an outwardly extending flange is positioned in said body member outwardly of said shoulder, said sleeve being adapted to be slipped between the dielectric layer surrounding said center conductor of said coaxial transmission line and the outer conductor thereof and said flange being adapted to make electrical contact with a metallic surface on said shoulder, and an externally threaded adapter nut is screwed into said threaded end of the body member, said nut having an axially extending bore adapted for the passage of said coaxiAl transmission line therethrough, and said bore having an enlarged camlike portion at its inner end adapted to clamp said outer conductor and its outer insulating sheath against said thin-walled sleeve with the inner end of said nut pressing said flange of the eyeletlike member against said shoulder of the body member, and a dielectric spacing sleeve having an axially extending bore adapted for the passage of said inner conductor therethrough is positioned in said body member between said flexible disk and said eyeletlike member, said spacing sleeve serving to press said flexible disk against said shoulder portion of said contact pin upon tightening of said adapter nut.
