Coaxial connector for cable with a solid outer conductor
View Patent ↗A coaxial connector with a connector body is provided with a connector body bore. A grip ring is retained within the connector body bore, and an outer diameter of the grip ring abuts an annular wedge surface provided with a taper between a maximum diameter proximate the connector end and a minimum diameter proximate the cable end. The wedge surface may be provided directly on the connector body bore sidewall or alternatively on an inner diameter of a clamp ring coupled to the cable end of the connector body. An inner diameter of the grip ring is provided with a grip surface. A spring contact is retained within the connector body bore. The grip surface and an inner diameter of the spring contact are dimensioned to receive the outer conductor from the cable end there through and to then couple with an outer diameter of the outer conductor.

4. The connector of claim 1 , wherein the spring contact is a helical coil spring.
5. The connector of claim 1 , wherein the grip surface has a curve corresponding to a corrugation trough of the solid outer conductor.
6. The coaxial connector of claim 1 , wherein the wedge surface is formed in a sidewall of the connector body bore.
7. The coaxial connector of claim 6 , further including an outer conductor seal abutting the connector end of the grip ring; the outer conductor seal dimensioned to seal between the connector body and the outer diameter of the outer conductor.
8. The connector of claim 1 , wherein the grip ring has a generally v-shaped cross-section.
9. The connector of claim 8 , wherein the grip surface has a curve corresponding to a corrugation trough of the solid outer conductor.
10. The connector of claim 1 , wherein the grip ring abuts cable end of the spring contact.
11. The connector of claim 10 , further including an outer conductor seal abutting the cable end of the grip ring; the outer conductor seal dimensioned to seal between the connector body and the outer diameter of the outer conductor.
12. The coaxial connector of claim 1 , further including a clamp ring coupled to the cable end of the connector body;
the wedge surface formed in an inner diameter of the clamp ring, proximate the connector end of the clamp ring.
13. The connector of claim 12 , further including an annular spacer between the spring contact and the grip ring.
14. The connector of claim 13 , wherein an outer diameter of the annular spacer abuts the wedge surface.
15. The coaxial connector of claim 12 , wherein the clamp ring is coupled to the cable end of the connector body by a retaining feature.
16. The connector of claim 15 , wherein the retaining feature is a thread between the connector body sidewall and an outer diameter of the clamp ring; the thread operable to drive the wedge surface towards the spring contact.
17. The connector of claim 15 , wherein the retaining feature is an annular snap groove provided in the sidewall of the connector body bore and a corresponding snap barb on an outer diameter of the clamp ring.
18. The connector of claim 17 , further including a thread between the connector body sidewall and an outer diameter of the clamp ring; the thread operable to drive the wedge surface towards the spring contact.
