Abstract
Abstract In a push-on cable connector assembly, the connector is merely pushed onto the coaxial cable and positive pressure devices maintain electrical continuity at points of contact between the outer conductor of the cable undergoing tests and that of the connector assembly and between the inner conductor of said cable and that of the connector assembly. A spring fingered ferrule provides positive contact pressure with the outer conductor of the coaxial cable. Uniquely, a resilient spring contact probe, commonly applied in production testing of printed circuit boards, is adapted as the center conductor of the push-on connector assembly and provides positive contact pressure between the center conductor of the cable undergoing tests and the center conductor of the push-on connector assembly. A standard coaxial connector of the designer's choice is provided as part of the push-on cable connector assembly.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
Coaxial connector means providing push-on connection to the end of a coaxial cable comprising slidable pressure contact means for slidably positioning said connector on the outer conductor of a coaxial cable and for maintaining contact therewith when so positioned so as to provide electrical continuity between itself and said outer conductor; and resilient in-line pressure contact means for resiliently maintaining in-line contact with the center conductor of a coaxial cable on whose outer conductor said slidable pressure contact means has been slidably positioned so as to provide electrical contact between itself and said center conductor.
Claim 2
Dependent Claim
95 words
Coaxial connector means providing push-on connection to the end of a coaxial cable comprising slidable pressure contact means for slidably positioning said connector on the outer conductor of a coaxial cable and for maintaining contact therewith when so positioned so as to provide electrical continuity between itself and said outer conductor; and resilient in-line pressure contact means for resiliently maintaining in-line contact with the center conductor of a coaxial cable on whose outer conductor said slidable pressure contact means has been slidably positioned so as to provide electrical contact between itself and said center conductor.
Claim 3
Dependent Claim
