Abstract
Abstract 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: 17
Claim 1
Independent Claim
225 words
A connector for terminating a semi-rigid coaxial cable of the type having a center conductor surrounded by a dielectric medium and an outer conductor having a given inner diameter, which comprises: a. a insert assembly comprising 1. a coupling nut having external threads on one end and a longitudinal bore therethrough, 2. an outer ferrule adapted to receive said cable, said ferrule having a sleeve and on one end of said sleeve a radially extending rim, said rim having a inwardly facing recess, said sleeve adapted to be positioned in said bore in said coupling nut, 3. a retaining ring having teeth on the inner edge, said ring positioned in said recess in said rim and adapted to fit onto said cable whereby said teeth grip said cable; and b. an adapter assembly comprising 1. an inner ferrule adapted to be inserted into said cable, said inner ferrule having an inner diameter substantially equal to the inner diameter of said outer conductor; 2. a connector body having a passageway therethrough with a portion therein adapted to receive said inner ferrule and internal threads at one end adapted to threadedly receive said insert assembly whereby as said coupling nut threadedly engages said connector body, said inner ferrule is driven into said cable positioned within said outer ferrule thereby expanding said outer conductor against said outer ferrule.
