Abstract

Claims (34)

1. A coaxial connector for use with a coaxial cable with an outer conductor, comprising:

a connector body provided with a connector body bore;

an annular coupling groove provided in the connector body bore open to a cable end of the connector body;

a clamp sidewall of the coupling grove angled inward from a bottom of the coupling groove;

a slip ring seated within the coupling body bore, provided with a plurality of coupling spring fingers extending towards a connector end, an inner diameter of the coupling spring fingers provided with a grip surface; and

an annular compression body seated on an outer diameter of the slip ring between a compression surface of the coupling body and an upward projecting compression body shoulder of the coupling spring fingers;

the connector body and the coupling body coupled together via threads;

the slip ring dimensioned for axial advancement of the coupling body along the threads to drive the compression body against the compression shoulder to exert a compression force against a leading edge of the outer conductor to clamp the leading edge of the outer conductor against the clamp sidewall.

2. The coaxial connector of claim 1 , further including a surface to surface positive stop between the clamp nut and the connector body that stops the compression force at a predetermined maximum torque by preventing further movement of the clamp nut towards the connector body.

3. The coaxial connector of claim 1 , wherein the slip ring is retained within the connector body bore by an outward projecting coupling shoulder at a cable end of the slip ring, the coupling shoulder seated within an annular retention groove of the coupling body.

4. The coaxial connector of claim 1 , further including a compression sidewall angled outward from the bottom of the coupling groove;

the coupling spring fingers driven radially inward towards the clamp sidewall by contact with the compression sidewall.

5. The coaxial connector of claim 1 , wherein the grip surface is a plurality of annular barbs.

6. The coaxial connector of claim 5 , wherein the annular barbs have 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.

7. The coaxial connector of claim 1 , wherein the compression body is a helical coil spring ring.

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. The coaxial connector of claim 1 , further including a plurality of jacket grip spring fingers extending from a cable end of the slip ring.

11. The coaxial connector of claim 10 , further including a jacket wedge shoulder of the coupling body bore; the jacket wedge shoulder biasing the jacket grip spring fingers radially inward as the coupling body advances along the threads.

12. A coaxial connector for use with a coaxial cable with an outer conductor, comprising:

a connector body provided with a connector body bore;

the connector body provided with an inward angled annular clamp sidewall;

a coupling body with a coupling body bore; a slip ring seated within the coupling body bore; the slip ring provided with a plurality of axially projecting coupling spring fingers, an inner diameter of the coupling spring fingers provided with a grip surface;

the connector body and the coupling body coupled together via threads;

the slip ring dimensioned for axial advancement of the coupling body along the threads to generate a compression force for the coupling spring fingers to clamp a leading edge of the outer conductor against the clamp sidewall.

13. The coaxial connector of claim 12 , further including a surface to surface positive stop between the clamp nut and the connector body that stops the compression force at a predetermined maximum torque by preventing further movement of the clamp nut towards the connector body.

14. The coaxial connector of claim 12 , wherein the slip ring is retained within the connector body bore by an outward projecting shoulder at the cable end seated within an annular retaining groove of the coupling body.

15. The coaxial connector of claim 14 , wherein the outward projecting shoulder is biased inward against the jacket by contact with an elastomeric gasket during the axial advancement.

16. The coaxial connector of claim 12 , further including a compression sidewall angled outward from the clamp sidewall;

the spring fingers driven radially inward towards the clamp sidewall by contact with the compression sidewall as the coupling body is advanced towards the connector body.

17. The coaxial connector of claim 12 , further including a plurality of jacket grip spring fingers extending from a cable end of the slip ring.

18. The coaxial connector of claim 17 , further including a jacket wedge shoulder of the coupling body bore; the jacket wedge shoulder biasing the jacket grip spring fingers radially inward as the coupling body advances along the threads.

19. The coaxial connector of claim 12 , wherein the slip ring is c-shaped.

20. The coaxial connector of claim 12 , wherein the plurality of coupling spring fingers extend from a connector end of the slip ring.
