Abstract

There is provided a coaxial cable connector for coupling an end of a coaxial cable to an outer diameter of a threaded interface port. The coaxial cable connector includes a connector body, a tubular inner post, and a sleeve member. The connector body has a first end, an opposing second end, and a bore therethrough. The inner post is disposed within the bore of the connector body, and includes a first end and a second end. The first end is adapted to engage the connector body so as to prevent relative axial movement with the connector body. The second end of the inner post is adapted to be inserted into the end of the coaxial cable. Either the first end of the connector body or the first end of the inner post includes a basket portion adapted to engage the threaded interface port. The basket portion includes an outer diameter, an inner diameter that is less than the outer diameter of the threaded interface port, and a relief element. The relief element is adapted to radially expand the outer diameter of the basket portion upon engaging the interface port. The sleeve member is disposed in overlaying relation to the basket portion, and includes an inner diameter that is less than the expanded outer diameter of the basket portion. The sleeve member is axially movable in relation to the basket portion from a first position to a second position to radially compress the basket portion.

Claims

1. A coaxial cable connector for coupling an end of a coaxial cable to an outer diameter of a threaded interface port, the connector comprising:

a connector body having a first end, an opposing second end, and a bore therethrough;

a tubular inner post disposed within the bore of the connector body, the inner post having a first end and a second end, the first end adapted to engage the connector body so as to prevent relative axial movement with the connector body, the second end of the inner post adapted to be inserted into the end of the coaxial cable;

wherein one of the first end of the connector body and the first end of the inner post includes a basket portion adapted to engage the threaded interface port, the basket portion comprising an outer diameter, an inner diameter that is less than the outer diameter of the threaded interface port, and a relief element adapted to radially expand the outer diameter of the basket portion upon engaging the interface port; and

a sleeve member disposed in overlaying relation to the basket portion, the sleeve member comprising an inner diameter that is less than the expanded outer diameter of the basket portion, the sleeve member being axially slidably movable in relation to the basket portion from a first position to a second position to radially compress the basket portion onto the threaded interface port, wherein the sleeve member includes a plurality of axial slots.

2. The coaxial cable connector of claim 1, wherein the relief element of the basket portion comprises a plurality of axial slots, permitting radial compression thereof.

3. The coaxial cable connector of claim 1, wherein the relief element of the basket portion comprises a material having elastic properties.

4. The coaxial cable connector of claim 1, wherein the sleeve member is made from plastic.

5. The coaxial cable connector of claim 1, wherein the sleeve member is made from metal.

6. The coaxial cable connector of claim 1, wherein the basket portion includes a set of internal threads.

7. The coaxial cable connector of claim 1, wherein the basket portion is made from an electrically conductive material.

8. The coaxial cable connector of claim 1, further comprising an axial locking element to impede the sleeve member from moving from the second position back to the first position.

9. The coaxial cable connector of claim 8, wherein the axial locking element comprises an annular protrusion on the inner diameter of the sleeve member and an outer annular protrusion on the connector body.

10. In combination, a coaxial cable connector for coupling an end of a coaxial cable to an outer diameter of a threaded port, the coaxial cable connector comprising:

a connector body having a first end, an opposing second end, and a bore therethrough;

an inner post having a first end and a second end, the second end of the post being disposed within the connector body and wherein the first end of one of the connector body and the inner post includes a basket portion and wherein the basket portion is defined by a cavity sized for engaging an interface port; and

a sleeve portion disposed in overlaying relation to the basket portion, the sleeve portion being axially slidably movable in relation to the basket portion from a first position to a second position to radially compress the basket portion onto the threaded interface port, wherein the sleeve portion includes a plurality of axial slots.

11. The combination as recited in claim 10, wherein the basket portion includes a cylindrical radial face having a plurality of axial slots defined therein.

12. The combination as recited in claim 10, wherein the sleeve member is made from plastic.

13. The combination as recited in claim 10, wherein the sleeve member is made from metal.

14. The combination as recited in claim 10, wherein the basket portion is made from an electrically conductive material.

15. The combination as recited in claim 10, wherein the basket portion includes a set of internal threads for engaging external threads of the interface port.

16. The combination as recited in claim 10, wherein the basket portion is formed in the first end of the inner post.

17. The combination as recited in claim 10, wherein the basket portion is formed in the first end of the connector body.

18. The combination as recited in claim 10, further including a compression member attached to the second end of the connector body for securing a prepared coaxial cable end.
