Abstract

A connector includes a fastener member and a single-body structured connector body having an exterior casing and integral interior post. The structuring of the connector body facilitates improved RF shielding and reduction of noise ingress into the connector. In one embodiment, a coaxial cable having a center conductor, a dielectric, a braided sheath, and a protective outer jacket is inserted onto the connector. The fastener member, in a pre-installed first configuration is slidably advanced onto the connector body and moved into a second configuration in which the fastener member coacts with the connector body so that the connector sealingly grips the coaxial cable. A threaded nut may be used to secure the connector to an interface port.

Claims

1. A connector for coupling an end of a coaxial cable to an interface port, the coaxial cable having a center conductor surrounded by a dielectric, the dielectric being surrounded by a protective outer jacket, said connector comprising:

a. a connector body for receiving the coaxial cable, wherein the connector body includes a first end, the first end including an opening defined by an exterior casing and an integral interior post, the post adapted to be inserted into an end of the coaxial cable around the dielectric and under the protective outer jacket thereof; and

,

b. a fastener member, wherein the fastener member causes the exterior casing of the connector body to be deformed inwardly toward the interior post of the connector body and against the protective outer jacket of the coaxial cable as received and as the fastener member is advanced over the connector body.

2. The connector of claim 1, wherein the opening is a ringed bore and is bounded by an interior wall facilitating integral structuring of the exterior shell and interior post of the connector body.

3. The connector of claim 1, further wherein the connector body comprises a second end, the second end having ringed flange.

4. The connector of claim 3, wherein the fastener member comprises a first end and opposing second end with a central passageway defined between the fastener member first end and the fastener member second end for allowing a portion of the coaxial cable to pass there through, the fastener member secured to the connector body prior to installation over said end of the coaxial cable in a preinstal led first configuration, the central passageway being dimensioned to compress the connector body radially inwardly when the fastener member is slidingly moved from the first preinstalled configuration toward the second end of the connector body.

5. The connector of claim 4, wherein the central passageway of the fastener member includes a ramped surface.

6. The connector of claim 5, wherein the central passageway of the fastener member further includes a first opening having a first diameter proximate with the first end and a second opening having a second diameter proximate with the second end, the second opening diameter being less than the first opening diameter, and wherein the ramped surface is positioned between the first opening and the second opening.

7. The connector of claim 6, wherein the first opening of the fastener member is dimensioned to radially compress the exterior casing of the first end of the connector body inwardly when the fastener member is in the first preinstalled configuration.

8. The connector of claim 6, wherein the first opening of the fastener member is dimensioned to provide a press-fit between the first end of the connector body and the fastener member when the fastener member is in the first preinstalled configuration.

9. The connector of claim 6, wherein the first opening has a constant diameter.

10. The connector of claim 6, wherein the first opening is tapered.

11. The connector of claim 4, wherein the fastener member is slidingly moved from the first preinstalled configuration toward the second end of said connector body without rotation.

12. The connector of claim 1, further comprising a threaded nut.

13. The connector of claim 12, wherein the threaded nut comprises an internal lip.

17. The connector of claim 5, wherein the central passageway of the fastener member further includes a first inner bore having a first diameter proximate with the first end and a second inner bore having a second diameter proximate with the second end, the second inner diameter being less than the first inner diameter, and wherein the ramped surface is positioned between the first inner bore and the second inner bore.

18. The connector of claim 17, wherein the first inner bore of the fastener member is dimensioned to radially compress the exterior casing of the first end of the connector body inwardly when the fastener member is in the first preinstalled configuration.

19. The connector of claim 17, wherein the first inner bore of the fastener member is dimensioned to provide a press-fit between the first end of the connector body and the fastener member when the fastener member is in the first preinstalled configuration.

20. The connector of claim 17, wherein the first inner bore has a constant diameter.

21. The connector of claim 17, wherein the first inner bore is tapered.

14. A connector for coupling an end of a coaxial cable to an interface port, the coaxial cable having a center conductor surrounded by a dielectric, the dielectric being surrounded by a protective outer jacket, said connector comprising:

a. a connector body for receiving the coaxial cable, wherein the connector body includes a first end and a second end, the first end including an opening partially defined by an unbroken surface extending between an exterior casing and an interior post, the post adapted to be inserted into an end of the coaxial cable around the dielectric and under the protective outer jacket thereof, the second end having a ringed flange; and

,

b. a fastener member having a first end and opposing second end with a central passageway defined between the fastener member first end and the fastener member second end for allowing a portion of the coaxial cable to pass there through, the fastener member secured to the connector body prior to installation over the end of the coaxial cable in a preinstalled first configuration, the central passageway being dimensioned to compress the connector body radially inwardly when the fastener member is slidingly moved from the first preinstalled configuration toward the second end of the connector body, wherein the fastener member causes the exterior casing of the connector body to be deformed inwardly toward the interior post of the connector body and against the protective outer jacket of the coaxial cable as received and as the fastener member is advanced over the connector body.

15. The connector of claim 14, wherein the opening is a ringed bore and is bounded by an integral interior wall facilitating the unbroken surface extending between the exterior casing and interior post of the connector body.

16. The connector of claim 14, wherein the central passageway of the fastener member includes a ramped surface.

22. The connector of claim 14, wherein the fastener member is slidingly moved from the first preinstalled configuration toward the second end of said connector body without rotation.

23. The connector of claim 14, further comprising a threaded nut.

24. The connector of claim 23, wherein the threaded nut comprises an internal lip.

25. A method of improving RF shielding and reducing noise ingress into a coaxial cable connector having a connector body and a post, said method comprising:

providing the post integral with the connector body, whereby the integration results in simultaneously providing for improved RF shielding and reduction in noise ingress into the connector.

26. The method of claim 25 further comprising a step of securely sealing a coaxial cable into the connector.

27. The method of claim 25 further comprising a step of attaching the connector to an interface port.

28. A method of improving RF shielding and reducing noise ingress into a coaxial cable connector, said method comprising:

a providing a connector, said connector including;

a1. a unitary connector body for receiving the coaxial cable, wherein the unitary connector body includes an exterior casing and an interior post,

a2. a fastener member, wherein the fastener member causes the opening of the connector body to be decreased as the fastener member is advanced over the connector body;

b. inserting a coaxial cable end through the fastener member and onto the connector body, wherein the connector body facilitates improved RF shielding and reduction of noise ingress into the connector; and

c. advancing the fastener member from a first preinstalled configuration to a second configuration such that a continuous seal and secure grip is formed between the connector and the coaxial cable.
