Abstract
Apparatus and method for preparing end of coaxial cable having foamed TFE primary insulation comprises steps of engaging first blades to make a first cut completely through the outer insulation and braid, then withdrawing the blades before making a second cut which penetrates only the outer insulation, then pulling the cable against the second blades to remove slugs of outer insulation and braid as an unit. Braid is subsequently flared by rotating a tool against the exposed braid, and primary insulation is axially compressed to expose the signal conductor.
Claims18
A method of preparing coaxial cable proximate the end thereof for termination to a coaxial electrical contact, said cable being of the type comprising a signal conductor, inner insulation surrounding said signal conductor, a braided metal shield surrounding said inner insulation, and an outer insulative jacket surrounding said shield, said method comprising the steps of:
- cutting through said outer insulative jacket and said shield circumferentially at a first distance from said end with blade means,
- withdrawing said blade means,
- cutting said outer insulative jacket circumferentially at a second distance from said end with said blade means, said second distance being greater than said first distance,
- removing the outer insulative jacket from said second distance to said end and said shield from said first distance to said end as a unit.
A method of preparing coaxial cable proximate the end thereof for termination to a coaxial electrical contact, said cable being of the type comprisng a signal conductor, inner insulation surrounding said signal conductor, a braided metal shield surrounding said inner insulation, and an outer insulative jacket surrounding said shield, said method comprising the steps of
- removing said outer jacket to a second distance from said end,
- removing said shield to a first distance from said end, said first distance being less than said second distance, said shield being exposed from said first distance to said second distance, said inner insulation being exposed from said first distance to said end,
- initially flaring the shield to a generally conical configuration, said flaring being accomplished by rotating a flaring tool against the exposed shield about a circumferential path on said shield, said tool radially compressing said inner insulation through said shield to cause said initial flaring.
A method of preparing coaxial cable proximate the end thereof for termination to a coaxial electrical contact, said cable being of the type comprising a signal conductor, inner insulation surrounding said signal conductor, a braided metal shield surrounding said inner insulation, and an outer insulative jacket surrounding said shield, said method comprising the steps of
- removing said outer jacket to a second distance from said end,
- removing said shield to a first distance from said end, said first distance being less than said second distance, said shield being exposed from said first distance to said second distance, said inner insulation being exposed from said first distance to said end
- initially flaring the shield to a generally conical configuration, said flaring being accomplished by clamping said outer jacket adjacent the exposed shield and rotating a tool against the cable about a circumferential path between the second distance and the end.
A method of preparing an end section of a coaxial cable for termination to an electrical coaxial contact, the coaxial cable comprising a signal conductor, inner insulation covering the signal conductor, an outer conductor covering the inner insulation, and an outer insulative jacket covering the outer conductor, the method comprising the steps of:
- cutting circumferentially through the outer insulative jacket and the outer conductor at a first position along the end section of the cable spaced inwardly from the end of the cable;
- cutting circumferentially through the outer insulative jacket at a second position along the end section of the cable spaced inwardly from the first position;
- and
- removing the outer insulative jacket from the second position to the end and the outer conductor from the first position to the end as a unit.
A method of preparing an end section of a coaxial cable for termination to an electrical coaxial contact, the coaxial cable comprising a signal conductor, inner insulation covering the signal conductor, an outer conductor covering the inner insulation, and an outer insulative jacket covering the outer conductor, the method comprising the steps of:
- cutting circumferentially through the outer insulative jacket at first and second positions along the end section of the cable spaced inwardly from the end of the cable, the first position being closer to the end than the second position, the outer conductor being also circumferentially cut through at first position;
- and
- removing the outer insulative jacket from the second position to the end and the outer conductor from the first position to the end as a unit.
