Abstract

A connector coaxial cable connector comprising a connector body having an outer ramped surface, a post, engageable with the connector body, a coupling member, axially rotatable with respect to the post, and a compression portion structurally integral with the connector body, the compression portion having a ramped inner surface, wherein the inner ramped surface is configured to cooperate with the outer ramped surface during compression of the compression portion onto a portion of the connector body. Furthermore, an associated method is also provided.

Claims

1. A coaxial cable connector comprising;

a connector body having an outer ramped surface;

a post, engageable with the connector body;

a coupling member, axially rotatable with respect to the post; and

a compression portion structurally integral with the connector body, the compression portion having a ramped inner surface,

wherein the inner ramped surface is configured to cooperate with the outer ramped surface when the compression portions breaks away from the connector body during compression of the compression portion onto a portion of the connector body.

2. The coaxial cable connector of claim 1, wherein the ramped inner surface of the compression portion acts a stress concentrator for consistent cracking in form and location during compression, when the compression portion breaks away from the connector body.

3. The coaxial cable connector of claim 1, 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.

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

5. The coaxial cable connector of claim 1, wherein the compression portion includes a first outer ramped surface proximate a forward end of the compression portion.

6. The coaxial cable connector of claim 1, wherein the connector body includes an external annular detent configured to interfere with the removal of a radial restriction member.

7. A coaxial cable connector comprising;

a connector body having a first end and a second end, the connector body including an outer ramped surface proximate the second end;

a post engageable with the connector body;

a coupling member, axially rotatable with respect to the post;

a compression portion sharing a frangible connection with the connector body, the frangible connection being defined by the outer ramped surface of the connector body and an internal annular groove.

8. The coaxial cable connector of claim 7, wherein the compression portion is configured to radially compress the second end of the connector body onto a coaxial cable.

9. The coaxial cable connector of claim 7, 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.

10. The coaxial cable connector of claim 7, wherein the radial restriction member includes an inwardly extending lip.

11. The coaxial cable connector of claim 7, wherein the compression portion includes a first outer ramped surface proximate a forward end of the compression portion.

12. The coaxial cable connector of claim 7, wherein the connector body includes an external annular detent configured to interfere with the removal of a radial restriction member.

13. A coaxial cable connector comprising;

a connector body having a first end and a second end, the connector body including an outer ramped surface proximate the second end;

a post engageable with the connector body;

a coupling member, axially rotatable with respect to the post;

a compression portion sharing a frangible connection with the connector body; and

a stress concentrator positioned proximate the frangible connection;

wherein the stress concentrator is an internal annular groove comprising two opposingly ramped inner surfaces.

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 includes an inwardly extending lip.

16. A method of fastening a coaxial cable to a coaxial cable, the method comprising:

providing a coaxial cable connector including;

a connector body having an outer ramped surface;

a post, engageable with the connector body;

a coupling member, axially rotatable with respect to the post; and

a compression portion structurally integral with the connector body, the compression portion having a ramped inner surface; and

axially compressing the compression portion to securably attach the connector to the coaxial cable and form an environmental seal around the coaxial cable, wherein the inner ramped surface is configured to cooperate with the outer ramped surface during the axial compression of the compression portion onto a portion of the connector body.
