Abstract

A connector used in coaxial cable communication applications, and more specifically to coaxial connectors having features for sealing against environmental contaminants, facilitating effective attachment to a corresponding interface port, and improving the efficiency of structures and processes for attaching the connectors to coaxial cables. Furthermore, an associated method is also provided.

Claims

1. A coaxial cable connector comprising;

a connector body;

a post, engageable with the connector body;

a coupling member, axially rotatable with respect to the connector body, the coupling member having a first end and opposing second end;

an outer sleeve engageable with the coupling member, the sleeve configured to rotate the coupling member;

a compression portion structurally integral with the connector body, wherein the compression portion is configured to break apart from the body when axially compressed; and

a radial restriction member, wherein at least some part of the radial restriction member is disposed radially extent of the compression portion to restrict radial expansion of the compression portion.

2. The coaxial cable connector of claim 1, wherein the radial restriction member comprises at least one strap positioned around at least a section of the compression portion.

3. The coaxial cable connector of claim 1, wherein the radial restriction member includes an inwardly extending lip.

4. The coaxial cable connector of claim 1, wherein the outer sleeve extends to the first end of the coupling member.

5. The coaxial cable connector of claim 1, wherein the outer sleeve extends beyond the first end of the coupling member, to guide the coupling member onto a corresponding port.

6. The coaxial cable connector of claim 1, wherein the outer sleeve includes an engagement member configured to mate with a retaining structure of the coupling member.

7. A coaxial cable connector comprising;

a connector body;

a post engageable with connector body;

a coupling member, axially rotatable with respect to the connector body, the coupling member having a first end and opposing second end portion;

a sealing element attached to the first end of the coupling member, wherein the sealing element prevents ingress of environmental elements proximate the first end of the coupling member that is configured to mate with a port; and

an outer sleeve engageable with the coupling member, the sleeve configured to rotate the coupling member.

8. The coaxial cable connector of claim 7, further comprising a compression portion.

9. The coaxial cable connector of claim 8, wherein the compression portion is a separate fastener member radially disposed over the connector body to radially compress the connector body onto a coaxial cable.

10. The coaxial cable connector of claim 8, wherein the compression portion is a separate insertable compression sleeve configured to be inserted within an opening of the connector body proximate a rearward end of the connector body.

11. The coaxial cable connector of claim 7, wherein the outer sleeve extends to the first end of the coupling member.

12. The coaxial cable connector of claim 7, wherein the outer sleeve includes an engagement member configured to mate with a retaining structure of the coupling member.

13. A coaxial cable connector comprising;

a connector body;

a post engageable with connector body;

a coupling member, axially rotatable with respect to the connector body, the coupling member having a first end and opposing second end;

a sealing element attached to the first end of the coupling member, wherein the sealing element prevents ingress of environmental elements proximate the first end of the coupling member that is configured to mate with a port; and

a compression portion structurally integral with the connector body, wherein the compression portion is configured to break apart from the body when axially compressed.

14. The coaxial cable connector of claim 13, further comprising a radial restriction member, wherein at least some part of the radial restriction member is disposed radially extent of the compression portion to restrict radial expansion of the compression portion.

15. The coaxial cable connector of claim 14, wherein the radial restriction member comprises at least one strap positioned around at least a section of the compression portion.

16. The coaxial cable connector of claim 14, wherein the radial restriction member includes an inwardly extending lip.

17. A method of fastening a coaxial cable to a communication port, the method comprising:

providing a coaxial cable connector including;

a connector body;

a post operably attached to the connector body;

a coupling member axially rotatable with respect to the connector body;

an outer sleeve engageable with the coupling member;

a compression portion structurally integral with the connector body; and

a radial restriction member, wherein at least some part of the radial restriction member is disposed radially extent of the compression portion to restrict radial expansion of the compression portion;

axially compressing the compression portion to form an environmental seal around the coaxial cable, wherein when axially compressed, the compression portion breaks away from the body and securely connects to the coaxial cable; and

fastening the coupling member to an interface port by operating the outer sleeve.

18. A coaxial cable connector comprising;

a connector body;

a post engageable with connector body;

a coupling member, axially rotatable with respect to the connector body, the coupling member having a first end and opposing second end;

a sealing element attached to the first end of the coupling member, wherein the sealing element prevents ingress of environmental elements proximate the first end of the coupling member that is configured to mate with a port;

a compression portion structurally integral with the connector body, wherein the compression portion is configured to break apart from the body when axially compressed; and

an outer sleeve engageable with the coupling member, the sleeve configured to rotate the coupling member.
