Abstract

Abstract A coaxial cable of the type comprising a litz wire with individually enameled strands as an inner conductor and a wire plait as an outer conductor is spliced to a coaxial connector by exposing a top of the inner conductor and stripping part of the insulation from the outer conductor to expose a portion thereof set back from the tip of the inner conductor. Before splicing, the stripped cable extremity is immersed in a solvent for the enamel such as sulfuric acid, then subjected to ultrasonic vibration in a bath containing alcohol or fluorinated hydrocarbons, and thereafter immersed in a solution of tin. After neutralization and drying, the conductor portions so treated are joined to corresponding conductors of the coaxial connector whereupon a sleeve is placed around the joint and crimped to secure the connector to the cable.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 154 words
A process for splicing a coaxial cable to a coaxial connector, said cable having an inner and an outer conductor at least one of which is composed of individually enameled wire strands, a first layer of insulation separating said conductors, and a second layer of insulation surrounding said outer conductor, comprising the steps of: (I) stripping away parts of said first and second layers to expose a tip of said inner conductor and a portion of said outer conductor, set back from said tip, on a cable extremity to be spliced; (II) immersing said cable extremity in a solvent for the enamel covering said wire strands; (III) removing the dissolved enamel by subjecting said cable extremity to ultrasonic vibration in a bath; (IV) immersing said extremity in a chemical tin-plating solution; and (V) thereafter joining said tip of said inner conductor and said portion of said outer conductor to corresponding conductors of said connector.
Claim 2
Dependent Claim 154 words
A process for splicing a coaxial cable to a coaxial connector, said cable having an inner and an outer conductor at least one of which is composed of individually enameled wire strands, a first layer of insulation separating said conductors, and a second layer of insulation surrounding said outer conductor, comprising the steps of: (I) stripping away parts of said first and second layers to expose a tip of said inner conductor and a portion of said outer conductor, set back from said tip, on a cable extremity to be spliced; (II) immersing said cable extremity in a solvent for the enamel covering said wire strands; (III) removing the dissolved enamel by subjecting said cable extremity to ultrasonic vibration in a bath; (IV) immersing said extremity in a chemical tin-plating solution; and (V) thereafter joining said tip of said inner conductor and said portion of said outer conductor to corresponding conductors of said connector.
Claim 3
Dependent Claim 13 words
A process as defined in claim 1 wherein said solvent is sulfuric acid.
Claim 4
Dependent Claim 14 words
A process as defined in claim 1 wherein said bath contains a fluorinated hydrocarbon.
Claim 5
Dependent Claim 33 words
A process as defined in claim 1, 2 or 3 comprising, after step (III), the further steps of immersing said cable extremity in a basic neutralizing solution and then drying said cable extremity.
Claim 6
Dependent Claim 13 words
A process as defined in claim 1 wherein said bath contains an alcohol.
