Clamp and grip coaxial connector
View Patent ↗A coaxial connector with a connector body is provided with a connector body bore. An annular coupling groove is provided in the connector body bore open to a cable end of the connector body. A clamp sidewall of the coupling grove is angled inward from a bottom of the coupling groove. A slip ring seated within the coupling body bore is provided with a grip surface. An annular compression body is positioned between the slip ring and the clamp sidewall. The connector body and the coupling body are coupled together via threads. The slip ring is dimensioned for axial advance of the coupling body along the threads to exert a compression force against the compression body to clamp a leading edge of the outer conductor between the compression body and the clamp sidewall.

5. The coaxial connector of claim 4 , wherein each of the annular barbs has a stop surface at a connector end and an insertion surface at a cable end; the stop surface provided normal to a longitudinal axis and a diameter of the insertion surface increasing towards the connector end.
6. The coaxial connector of claim 1 , wherein the compression body seats within a compression body groove of the coupling spring fingers.
7. The coaxial connector of claim 6 , wherein the coupling spring fingers extend toward the cable end farther than the compression body.
8. The coaxial connector of claim 1 , wherein the threads are multiple interleaved threads.
9. The coaxial connector of claim 1 , further including a sealing gasket seated between a cable end of the slip ring and an inward projecting sealing gasket shoulder of the coupling body bore.
10. A coaxial connector for use with a coaxial cable with an outer conductor, comprising:
