Abstract
Abstract This invention relates to a coaxial cable connector featuring inner and outer ferrules between which the outer conductor of a semi-rigid cable is squeezed. The assembly of the connector onto the cable is accomplished with ordinary standard hand wrenches operating on an outer coupling containing the outer ferrule nut threadedly engaging a connector body containing the inner ferrule. The structure of the connector preserves the critical diameters of the coaxial cable thereby reducing or eliminating reflective loss of radio frequency energy.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
220 words
A method of terminating a semi-rigid coaxial cable having a metallic tubular outer conductor onto a connector comprising the steps of: a. staking an inner ferrule into a connector body having a bore therethrough; b. inserting a outer ferrule having a rim and a sleeve projecting axially from said rim, through a coupling nut until said rim engages an end of said nut, c. flaring an end of said sleeve protruding from the end of said coupling nut opposite said end engaging said rim thereby securing said outer ferrule to said coupling nut; d. staking a cable retaining ring having inwardly facing serrations into a inwardly facing recess in said rim; e. sliding a guage over external threads on said coupling nut; f. threading said coupling nut into said connector body until said connector body engages said guage; g. inserting an end of said coaxial cable through said outer ferrule and through said retaining ring until said cable abuts said inner ferrule and whereby said serrations grip said cable; h. removing said connector body from said coupling nut; i. removing said guage from said coupling nut; j. re-threading said connector body onto said coupling nut thereby driving said inner ferrule into said tubular outer conductor causing said outer conductor and said sleeve on said outer ferrule to radially deform outwardly.
Claim 2
Independent Claim
220 words
A method of terminating a semi-rigid coaxial cable having a metallic tubular outer conductor onto a connector comprising the steps of: a. staking an inner ferrule into a connector body having a bore therethrough; b. inserting a outer ferrule having a rim and a sleeve projecting axially from said rim, through a coupling nut until said rim engages an end of said nut, c. flaring an end of said sleeve protruding from the end of said coupling nut opposite said end engaging said rim thereby securing said outer ferrule to said coupling nut; d. staking a cable retaining ring having inwardly facing serrations into a inwardly facing recess in said rim; e. sliding a guage over external threads on said coupling nut; f. threading said coupling nut into said connector body until said connector body engages said guage; g. inserting an end of said coaxial cable through said outer ferrule and through said retaining ring until said cable abuts said inner ferrule and whereby said serrations grip said cable; h. removing said connector body from said coupling nut; i. removing said guage from said coupling nut; j. re-threading said connector body onto said coupling nut thereby driving said inner ferrule into said tubular outer conductor causing said outer conductor and said sleeve on said outer ferrule to radially deform outwardly.
Claim 3
Dependent Claim
33 words
The method of claim 1 adding the step of longitudinally extruding said outer conductor adjacent to said rim on said outer ferrule during said re-threading of said connector body onto said coupling nut.
Claim 4
Independent Claim
214 words
A method of terminating a semi-rigid coaxial cable having a metallic tuBular outer conductor onto a connector comprising the steps of: a. staking an inner ferrule into a connector body having a bore therethrough; b. inserting a outer ferrule having a rim and a sleeve projecting axially from said rim, through a coupling nut until said rim engages an end of said nut; c. flaring an end of said sleeve protruding from the end of said coupling nut opposite said end engaging said rim thereby securing said outer ferrule to said coupling nut; d. staking a cable retaining ring having inwardly facing serrations into a inwardly facing recess in said rim; e. placing a gauge over external threads on said coupling nut; f. threading said coupling nut into said connector body until said connector body engages said gauge; g. inserting an end of said coaxial cable through said outer ferrule and through said retaining ring until said cable abuts said inner ferrule and whereby said serrations grip said cable; h. removing said gauge from said coupling nut; i. continuing the threading of said connector body onto said coupling nut thereby driving said inner ferrule into said tubular outer conductor causing said outer conductor and said sleeve on said outer ferrule to radially deform outwardly.
Claim 5

214 words
A method of terminating a semi-rigid coaxial cable having a metallic tuBular outer conductor onto a connector comprising the steps of: a. staking an inner ferrule into a connector body having a bore therethrough; b. inserting a outer ferrule having a rim and a sleeve projecting axially from said rim, through a coupling nut until said rim engages an end of said nut; c. flaring an end of said sleeve protruding from the end of said coupling nut opposite said end engaging said rim thereby securing said outer ferrule to said coupling nut; d. staking a cable retaining ring having inwardly facing serrations into a inwardly facing recess in said rim; e. placing a gauge over external threads on said coupling nut; f. threading said coupling nut into said connector body until said connector body engages said gauge; g. inserting an end of said coaxial cable through said outer ferrule and through said retaining ring until said cable abuts said inner ferrule and whereby said serrations grip said cable; h. removing said gauge from said coupling nut; i. continuing the threading of said connector body onto said coupling nut thereby driving said inner ferrule into said tubular outer conductor causing said outer conductor and said sleeve on said outer ferrule to radially deform outwardly.
Claim 6
Dependent Claim
33 words
