Dielectric spacer for coaxial cable and connector
Coaxial connectors include: a generally cylindrical inner contact configured at one end to mate with a corresponding inner contact of a mating connector and at an opposite end to engage an inner conductor of a coaxial cable; a generally cylindrical outer conductor body spaced apart from and circumferentially surrounding the inner contact and configured at one end to mate with a corresponding outer conductor body contact of a mating connector and at an opposite end to electrically connect with an outer conductor of the coaxial cable; a first dielectric spacer interposed between the inner contact and the outer conductor body; and a second dielectric spacer interposed between the inner contact and the outer conductor body and including axially-extending fingers. The second dielectric spacer engages the outer conductor body so that the fingers exert radially-inwardly directed pressure on the inner conductor of the coaxial cable that engages the inner contact.
1. A coaxial connector, comprising:

a first dielectric spacer interposed between the inner contact and the outer conductor body; and
a second dielectric spacer interposed between the inner contact and the outer conductor body, the second dielectric spacer including axially-extending fingers;
