Abstract

A coaxial cable connector includes an internal compression ring that provides a weather seal for a wide range of coaxial cable diameter sizes. The compression ring includes a flexing portion with a defined recessed section designed to flex outwardly when in contact with a wide diameter coaxial cable. With larger cables, the wall flexes more, while with smaller cables the wall flexes less, if at all, providing a seal in all cases.

Claims

1. A compression connector connectable to one of a plurality of coaxial cables having different sized outer diameters, each cable having a center conductor, a dielectric insulator surrounding the center conductor, a conductive shield surrounding the dielectric insulator, and an outer protective insulating jacket, the compression connector comprising:

a main body defining an internal cavity;

a compression ring connected to one end of the main body;

the compression ring having an annular recess in an outer circumference thereof defining a flexible wall area of the compression ring; and

the annular recess forming a flexing space between the flexible wall area of the compression ring and the main body;

wherein the flexible wall area has a flexing range between a first position corresponding to a smallest outer diameter of the plurality of coaxial cables and a second position corresponding to a largest outer diameter of the plurality of coaxial cables;

the flexing range of the flexible wall area effective for permitting any one of the plurality of coaxial cables having different sized outer diameters;

such that when the coaxial cable is fully secured in the compression connector, the flexible wall area is within the flexing range.

2. A connector according to claim 1 further comprising an internal post mounted inside the main body, the internal post having a cross-section such that the internal post is effective for passing between the dielectric insulator and the outer protective insulating jacket of the coaxial cable inserted into the main body through the compression ring.

3. A connector according to claim 1, wherein the flexible wall area flexes outwardly into the flexing space when the compression ring is inserted into the main body after a coaxial cable is inserted into the connector.

4. A connector according to claim 1 wherein the compression ring has a first inner diameter at a first end, the first end being the end through which an inserted coaxial cable passes when inserted into the connector;

and the flexible wall area of the compression ring has a second inner diameter, smaller than the first inner diameter.

5. A connector according to claim 1 wherein the compression ring is made of metal, metallic alloy, composite, or plastic.

6. A compression connector connectable to one of a plurality of coaxial cables having different sized outer diameters, each cable having a center conductor, a dielectric insulator surrounding the center conductor, a conductive shield surrounding the dielectric insulator, and an outer protective insulating jacket, the compression connector comprising:

a main body defining an internal cavity;

a compression ring connected to one end of the main body;

the compression ring including flexing means for flexing outwardly towards the main body when a coaxial cable is inserted into the connector and the compression ring is fully inserted into the main body,

wherein the flexing means includes a flexing range between a first position corresponding to a smallest outer diameter of the plurality of coaxial cables and a second position corresponding to a largest outer diameter of the plurality of coaxial cables;

the flexing range of the flexing means effective for permitting any one of the plurality of coaxial cables having different sized outer diameters;

such that when the coaxial cable is fully secured in the compression connector, at least a portion of the flexing means is within the flexing range.

7. A connector according to claim 6 further comprising an internal post mounted inside the main body, the internal post having a cross-section such that the internal post is effective for passing between the dielectric insulator and the outer protective insulating jacket of the coaxial cable inserted into the main body through the compression ring.

8. A connector according to claim 6 wherein the flexing means is made of metal, metallic alloy, composite, or plastic.

9. A compression connector according to claim 6, wherein the flexing means includes an annular recess in an outer circumference thereof forming a flexible wall area of the compression ring;

and the annular recess forms a flexing space between the flexible wall area of the compression ring and the main body.

10. A connector according to claim 9 wherein the compression ring has a first inner diameter at a first end, the first end being the end through which the inserted coaxial cable passes when inserted into the connector;

and the flexible wall area of the compression ring has a second inner diameter, smaller than the first inner diameter.

11. A method of manufacturing a compression connector connectable to one of a plurality of coaxial cables having different sized outer diameters, comprising the steps of:

making a main body;

making a threaded nut body connected to the main body at a first end thereof;

making a compression ring connected to the main body at a second end thereof; and

forming an annular groove in an outer portion of the compression ring, thereby defining a flexible wall area in the compression ring,

wherein the flexible wall area has a flexing range between a first position corresponding to a smallest outer diameter of the plurality of coaxial cables and a second position corresponding to a largest outer diameter of the plurality of coaxial cables; and

the flexing range of the flexible wall area is effective for permitting any one of the plurality of coaxial cables having different sized outer diameters;

such that when the coaxial cable is fully secured in the compression connector, the flexible wall area is within the flexing range.

12. A method according to claim 11, wherein the flexible wall area has an inner diameter greater than or equal to an outer diameter of the coaxial cable.

13. A method according to claim 12, wherein the compression ring has a first inner diameter at an end through which an inserted coaxial cable passes when inserted into the connector;

and the flexible wall area of the compression ring has a second inner diameter, smaller than the first inner diameter.

14. A connector according to claim 13 further comprising the step of mounting an internal post inside the main body, the internal post having a cross-section such that the internal post is effective for passing between the dielectric insulator and the outer protective insulating jacket of the coaxial cable inserted into the main body through the compression ring.
