Abstract

Coaxial connectors include a connector body and an inner contact post. A compression sleeve is also provided that is configured to impart a generally circumferential compressive force to secure one or more elements of a coaxial cable between the connector body and the inner contact post when the compression sleeve is in a seated position. The compression sleeve or the connector body includes a first disengagement mechanism that is configured to assist moving the compression sleeve from the seated position to an unseated position in which at least some of the circumferential compressive force is eliminated.

Claims

1. A coaxial connector, comprising:

a connector body;

an inner contact post that is at least partly within the connector body;

a compression element that is configured to impart a generally circumferential compressive force to secure one or more elements of a coaxial cable between the connector body and the inner contact post when the compression element is in a seated position;

wherein at least one of the compression element or the connector body includes a first disengagement mechanism that is configured to assist moving the compression element from the seated position to an unseated position in which at least some of the circumferential compressive force is eliminated.

2. The coaxial connector of claim 1, wherein the compression element comprises a compression sleeve, and wherein the first disengagement mechanism comprises a first cammed surface on the connector body and a second mating cammed surface on the compression element.

3. The coaxial connector of claim 1, wherein the first disengagement mechanism comprises a first surface on the connector body that is arranged in an inclined mating relationship with a second surface on the compression element.

4. The coaxial connector of claim 1, wherein the first disengagement mechanism comprises a first set of threads on a surface of the connector body and a second, mating set of threads on the compression element.

5. The coaxial connector of claim 1, wherein at least one of the compression element or the connector body includes a second disengagement mechanism that is configured to operate independent of the first disengagement mechanism.

6. The coaxial connector of claim 5, wherein the first disengagement mechanism comprises a first surface on the connector body that is arranged in an inclined mating relationship with a second surface on the compression element and wherein the second disengagement mechanism comprises a first set of threads on a surface of the connector body and a second, mating set of threads on the compression element.

7. The coaxial connector of claim 1, wherein at least one of the compression element or the connector body includes at least one raised projection and the other of the compression element or the connector body includes at least one mating recess that is configured to receive a respective one of the raised projection(s).

8. The coaxial connector of claim 7, wherein the at least one raised projection comprises an annular ridge and the at least one mating recess comprises an annular groove.

9. The coaxial connector of claim 8, wherein the annular ridge is configured to forcibly engage the annular groove when the compression element and connector body are fully seated together with a retention force that opposes axially reversing forces sufficient to meet SCTE requirements.

10. The coaxial connector of claim 8, wherein the annular ridge is configured to forcibly engage the annular groove when the compression element and connector body are fully seated together sufficiently to block water ingress.

11. The coaxial connector of claim 7, wherein a bottom portion of the connector body includes an open area that is configured to receive excess end portions of electrical shielding wires of a coaxial cable that is attached to the coaxial connector when the compression element is in the seated position.

12. The coaxial connector of claim 1, wherein the compression element is pre-mounted on the connector body in an extended, unseated position in which the connector is ready to receive a prepared end of a coaxial cable, and wherein the compression element is configured to be moved into a seated position by axially inserting the compression element into or over the connector body, thereby securing the end of the coaxial cable to the connector.

13. The coaxial connector of claim 4, wherein the first and second sets of threads are arranged relative to each other and are formed of a material such that the compression element may be forcibly driven axially into the connector body into the seated position without permanently deforming either the first or second sets of threads.

14. The coaxial connector of claim 13, wherein at least one of the compression element or the connector body includes an annular ridge and the other of the compression element or the connector body includes an annular groove that is configured to receive the annular ridge when the compression element is in the seated position.

15. The coaxial connector of claim 1, wherein the compression element is configured to indirectly impart a compressive force on a coaxial cable that is attached to the connector when the compression element is in the seated position.

16. The coaxial connector of claim 1, wherein the connector body is at least partly within the compression element when the compression element is in the seated position.

17. The coaxial connector of claim 1, wherein at least one of the connector body and the compression element includes an alignment feature.

18. The coaxial connector of claim 17, wherein the alignment feature comprises a visual alignment indicia that specifies the proper alignment of connector body with respect to the compression element prior to moving the compression element into its seated position.

19. The coaxial connector of claim 17, wherein the alignment feature comprises a protrusion on one of the compression element or the connector body and a mating recess on the other of the compression element or the connector body, wherein the protrusion and recess are positioned so that the protrusion fits within the recess when the connector body is in proper alignment with the compression element for moving the compression element into its seated position.

20. A method of reusing a coaxial connector that is installed on a first coaxial cable on a second coaxial cable, the method comprising:

unseating a compression sleeve of the coaxial connector from a seated position in which the compression sleeve and connector body of the coaxial cable together impart a compressive force on the first coaxial cable;

removing the first coaxial cable from the coaxial connector;

inserting the second coaxial cable within the connector body;

moving the compression sleeve into the seated position so that the compression sleeve and connector body together impart a compressive force on the second coaxial cable.

21. The method of claim 20, wherein unseating the compression sleeve from the seated position comprises popping an annular ridge that is provided on one of the compression sleeve or connector body from an annular groove that is provided on the other of the compression sleeve or connector body.

22. The method of claim 20, wherein unseating the compression sleeve from the seated position comprises rotating the compression sleeve relative to the connector body in order to activate a disengagement mechanism that provides a mechanical advantage for unseating the compression sleeve from the seated position.

23. The method of claim 22, wherein the disengagement mechanism comprises a first set of threads on the connector sleeve and a second set of threads on the connector body that are configured to mate with the first set of threads.

24. The method of claim 23, wherein unseating a compression sleeve of the coaxial connector from the seated position comprises rotating the compression sleeve relative to the connector body to unscrew the compression sleeve from the connector body, and wherein moving the compression sleeve into the seated position so that the compression sleeve and connector body together impart a compressive force on the second coaxial cable comprises forcibly axially inserting one of the compression sleeve or the connector body into the other of the compression sleeve or connector body so that the first set of threads and the second set of threads jump each other during the insertion process.

25. The method of claim 24, wherein the compression sleeve and connector body each include mating cammed or inclined surfaces.
