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

1. 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.

2. The coaxial connector means of claim 1 wherein said slidable pressure contact means comprises annular spring finger means for enveloping said outer conductor of a coaxial cable and maintaining electrical contact therewith.

3. The coaxial connector means of claim 1 wherein said resilient pressure contact means comprises a spring loaded extensible center conductor of said coaxial connector means.

4. The coaxial connector means of claim 1 further comprising coaxial transition means coupled to both said slidable and said resilient in-line pressure contact means for providing impedance matched electrical continuity to standard coaxial connector means.

5. The coaxial connector means of claim 4 further comprising coupling means for coupling a standard coaxial connector to said transition means.

6. The coaxial connector means of claim 5 wherein said coaxial transition means comprises:

outer conductor means coupled to said slidable pressure contact means; and

inner conductor means coupled to said resilient in-line pressure contact means.

7. The coaxial connector means of claim 6 wherein said inner conductor means comprises a spring loaded extensible shaft.

8. The coaxial connector means of claim 7 wherein said resilient in-line pressure contact means comprises an in-line pressure contact coupled to said spring loaded extensible shaft.

9. The coaxial connector means of claim 8 wherein said inner conductor means further comprises coupling means for coupling said inner conductor means to the center conductor of standard coaxial connector means.

10. The coaxial connector means of claim 5 wherein said inner conductor means comprise a resilient spring contact probe as is generally employed in production testing of bare and loaded printed circuit boards, wire wrapped back planes and in other applications where circuit access requires a compliant contact system.
