Abstract

A coaxial connector for interconnection with a coaxial cable with a solid outer conductor by friction welding is provided with a monolithic connector body with a bore dimensioned for an interference fit with an outer diameter of the outer conductor. A friction groove may be formed around the leading end of the outer conductor by application of a friction weld support against the inner diameter and leading end of the outer conductor. The friction groove may include a material chamber formed between a radial friction protrusion of the bore and a bottom of the friction groove. The friction weld support may be provided with ceramic surfaces contacting the outer conductor, a stop shoulder dimensioned to abut a cable end of the bore and/or an elastic insert seated within an inner conductor bore.

Claims (8)

1. A friction weld support for friction welding a coaxial connector with a solid outer conductor coaxial cable; comprising:

an insert body with a cable end insert portion with an outer diameter dimensioned to seat within an inner diameter of the outer conductor;

the insertion portion is ceramic material;

the insert body provided with a stop shoulder at a connector end of the insert portion; the stop shoulder dimensioned to abut a connector end of a bore of a connector body of the coaxial connector;

the insert portion operative as an inner sidewall of an annular friction groove formed upon insertion of a leading end of the outer conductor into the bore and insertion of the insert portion into the inner diameter of the outer conductor, the stop shoulder abutting the connector end of the bore.

2. The support of claim 1 , further including an extraction shoulder proximate a connector end of the insert body.

3. The support of claim 1 , further including an inner conductor bore in the insert body, coaxial with the insertion portion; a diameter of the inner conductor bore greater than an outer diameter of an inner conductor of the coaxial cable.

4. The support of claim 3 , further including an elastic insert, seated within the inner conductor bore.
