Abstract
Abstract A method and apparatus for securing a connector to a coaxial cable, and in particular to a multilayer core coaxial cable, without causing any damage or disturbance to the core. A split ferrule is fitted together over an exposed portion of the core at the end of the cable and is then pushed back with a sleeve formed on the rear of the ferrule being forced between the cable core and outer conductor. When the ferrule is in place, it is secured to the cable by suitable means, such as crimping, and the forward portion of the ferrule is utilized to secure the ferrule, and thus the cable, to a connector body.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
231 words
A method of securing a connector to a multilayer core coaxial cable having an inner and an outer conductor comprising the steps of: sliding a cylindrical crimp ferrule and a cylindrical connector member onto said cable, said connector member having a cylindrical bore of diameter slightly larger than that of said cable and an enlarged counterbore; trimming a predetermined amount of said outer conductor from the end of said cable; fitting the segments of a split ferrule together over the exposed end of said cable core, said ferrule, when fitted together, having an enlarged cylindrical portion, an elongated cylindrical sleeve of smaller diameter concentric with said enlarged portion, and a flat surface formed perpendicular to the axis of said ferrule on the enlarged portion end thereof; sliding said fitted-together ferrule up said core with said sleeve being forced between said core and said outer conductor; moving said connection member into engagement with said fitted-together ferrule with at least a portion of said enlarged portion fitted in said counterbore, and securing said member, and thus also said ferrule, to a mating connector body; crimping said crimp ferrule over the portion of said outer conductor which is over said ferrule sleeve; and utilizing the flat, enlarged portion end of said split ferrule, when its sleeve is properly positioned between said outer conductor and said core, as a trimming jig for trimming said core.
