Abstract

Connectors and methods for attaching connectors to one or more cables and/or conduits are disclosed. The disclosed connectors and methods may secure an outer surface of the cable (e.g., an outer jacket of a cable) or conduit. A front coupler sleeve engages a sub-assembly comprising a back coupler sleeve and an actuator sleeve disposed around the cable or conduit. During engagement of an inner surface of the front coupler sleeve and an outer surface of the back coupler sleeve, an at least partially annular protrusion of the back coupler sleeve is displaced radially inwardly to secure the outer surface of the cable or conduit.

Claims

1. A connector for securing an outer surface of a cable or conduit, the connector comprising:

a back coupler sleeve comprising at least one inner surface defining a back coupler sleeve opening extending through the back coupler sleeve, an outer surface and an at least partially annular protrusion formed along the inner surface within the back coupler sleeve opening;

an actuator sleeve comprising an outer surface and an inner surface, the inner surface defining an actuator sleeve opening extending through the actuator and adapted to receive the cable, the inner surface including a tapered portion adapted to at least partially receive the at least partially annular protrusion of the back coupler sleeve within the actuator sleeve opening, the actuator sleeve inserted into the back coupler sleeve opening of the back coupler sleeve and disposed adjacent to the at least partially annular protrusion of the back coupler sleeve; and

a front coupler sleeve comprising an inner surface disposed about at least a portion of the outer surface of the back coupler sleeve and at least a portion of the outer surface of the actuator sleeve and adapted to engage the outer surface of the back coupler sleeve,

wherein engagement of inner surface of the front coupler sleeve and the outer surface of the back coupler sleeve is adapted to displace the at least partially annular protrusion of the back coupler sleeve radially inwardly to secure the outer surface of the cable or conduit.

2. The connector of claim 1 wherein the cable connector is adapted to secure the outer surface of at least one of a coaxial cable, a cored coaxial cable and a tube adapted to provide a conduit for receiving one or more cables within an opening of the tube.

3. The connector of claim 1 wherein the front coupler sleeve comprises a front nut including a front coupler sleeve threaded portion disposed along the front coupler sleeve inner surface.

4. The connector of claim 3 wherein the back coupler sleeve comprises a back coupler sleeve threaded portion disposed along the back coupler sleeve outer surface and adapted to engage the front coupler sleeve threaded portion to axially displace the back coupler sleeve relative to the front coupler sleeve.

5. The connector of claim 1 wherein the inner surface of the front coupler sleeve defines a front opening and a back opening adapted to receive the back coupler sleeve, the front opening disposed on an opposing end from the back opening.

6. The connector of claim 5 further comprising a packing coupler sleeve and packing sleeve, the packing coupler sleeve comprising an outer surface adapted to engage with the inner surface of the front coupler sleeve defining the front opening of the front coupler sleeve and the packing sleeve adapted to be retained between the packing coupler sleeve and the front coupler sleeve.

7. The connector of claim 6 wherein the outer surface of the packing coupler sleeve comprises a packing coupler sleeve threaded portion adapted for threadably engaging a second threaded portion of the front coupler sleeve disposed on an inner surface of the front opening of the front coupler sleeve.

8. The connector of claim 6 wherein a through-bore connects the front opening and the back opening of the front coupler sleeve.

9. The connector of claim 8 wherein the packing sleeve comprises a tapered portion adapted to be driven against a conical portion of the through-bore of the front coupler sleeve.

10. The connector of claim 8 wherein the front opening, back opening and through-bore of the front coupler sleeve form a continuous opening through the front coupler sleeve.

11. The connector of claim 10 wherein the continuous opening is adapted to receive a tubing providing a feed-through assembly extending through the connector.

12. The connector of claim 1 wherein the back coupler sleeve comprises an axially extending port disposed extending from a back end of the back coupler sleeve.

13. The connector of claim 12 wherein a grounding wire is coupled to the back coupler sleeve within the axially extending port.

14. The connector of claim 1 wherein the actuator sleeve comprises a ferrule.

15. The connector of claim 1 wherein an outer surface of the actuator sleeve forms a recess adapted to engage a lip of the back coupler sleeve to restrict axial movement of the actuator sleeve with respect to the back coupler sleeve.

16. The connector of claim 1 wherein a collapsible ring is disposed between the actuator sleeve and the back coupler sleeve.

17. The connector of claim 1 wherein a plurality of rings are disposed between the actuator sleeve and the back coupler sleeve.

18. The connector of claim 1 wherein the at least partially annular protrusion comprises an annular ring extending from the inner surface of the back coupler sleeve.
