Abstract

A coaxial connector is provided with a connector body dimensioned to couple with the outer conductor, an insulator supporting an inner contact coaxial within a bore of the connector body. A spring contact may be positioned to contact an end of the inner conductor. Alternatively, an adapter may be mountable in an adapter bore of the inner contact, the adapter bore open to a cable end of the inner contact. The spring contact mountable within the adapter bore, the spring contact biasing the adapter against an end of the inner conductor.

Claims
