Abstract

A coaxial connector torque aid, in the form of a tubular grip element, is installed over a conventional coaxial connector to facilitate tightening of the connector onto an equipment port by hand. The tubular grip element includes an outer surface for being grasped by a user, and an internal bore for extending over the connector body. The tubular grip element is axially-slidable for being axially advanced to extend over, and fixedly engage, an outer surface portion of the nut, simultaneously with axial compression of the connector over an end of a coaxial cable. The tubular grip element has an axial length exceeding that of the nut to make the nut more accessible.

Claims

1. A method for facilitating rotation of a coaxial connector relative to a coaxial port, said method comprising the steps of:

a. providing a coaxial connector, the connector including a generally-cylindrical body for receiving a prepared end of a coaxial cable, and including a nut rotatably secured to the body for securing the connector onto a coaxial port, the nut including an outer surface;

b. providing a tubular grip element having an outer surface, an axial length, and an internal bore having a first end and an opposite second end, the internal bore having a circular cross-section with a constant inner diameter extending from the first end to the second end;

c. inserting the prepared end of a coaxial cable inside the body;

d. disposing the body of the connector inside the internal bore of the tubular grip element;

e. following steps c) and d), inserting the connector, tubular grip element, and coaxial cable into an axial compression tool; and

f. activating the axial compression tool to axially advance the tubular grip element to extend over, and non-rotatably press-fit engage, an outer surface portion of the nut.

2. The method of claim 1 wherein the coaxial connector is an axial compression-style coaxial connector, and wherein said activating step includes the step of securing the prepared end of the coaxial cable within the body simultaneously with the axial advancement of the tubular grip element over the outer surface portion of the nut.

3. The method of claim 1 wherein the nut of the coaxial connector has an axial length, and wherein the tubular grip element has an axial length, the axial length of the tubular grip element exceeding the axial length of the nut.

4. The method of claim 1 wherein the outer surface of the tubular grip element has a cylindrical surface.

5. The method of claim 1 wherein the outer surface of the tubular grip element comprises a plurality of flats.

6. The method of claim 5 wherein adjacent flats are joined to each other along common edges, and wherein each common edge is rounded.

7. The method of claim 5 wherein the plurality of flats includes four such flats.

8. The method of claim 5 wherein the plurality of flats includes six such flats.

9. The method of claim 5 wherein the plurality of flats includes eight such flats.

10. The method of claim 1 wherein step c) is performed before step d).

11. The method of claim 10 further including the step of inserting the prepared end of the coaxial cable inside the internal bore of the tubular grip element, and sliding the tubular grip element back along the coaxial cable, before performing step c).

12. A coaxial cable connector comprising in combination:

a. a coaxial connector, the connector including a generally-cylindrical body for receiving a prepared end of a coaxial cable, and including a nut rotatably secured to the body for securing the connector onto a coaxial port, the nut having an axial length and including an outer surface, and the body having an outer diameter of a predetermined dimension; and

b. a tubular grip element having an outer surface, an axial length, and an internal bore having a first end and an opposite second end, the tubular grip element having an axial length exceeding the axial length of the nut, the internal bore having a circular cross-section with a constant inner diameter extending from the first end to the second end, the body of the connector being disposed inside the internal bore of the tubular grip element, the tubular grip element being axially-slidable, relative to the body of the connector, for being axially advanced to extend over, and non-rotatably press-fit engage, an outer surface portion of the nut, the outer surface of the tubular grip element providing a surface that can be grasped by the fingers of a user to facilitate tightening of the nut to a coaxial port.

13. The coaxial cable connector of claim 12 wherein the tubular grip element fixedly engages the outer surface portion of the nut when axially advanced to extend over the outer surface portion of the nut.

14. The coaxial cable connector of claim 12 wherein the outer surface of the tubular grip element has a cylindrical surface.

15. The coaxial cable connector of claim 12 wherein the outer surface of the tubular grip element comprises a plurality of flats.

16. The coaxial cable connector of claim 15 wherein adjacent flats are joined to each other along common edges, and wherein each common edge is rounded.

17. The coaxial cable connector of claim 15 wherein the plurality of flats includes four such flats.

18. The coaxial cable connector of claim 15 wherein the plurality of flats includes six such flats.

19. The coaxial cable connector of claim 15 wherein the plurality of flats includes eight such flats.

20. The coaxial cable connector of claim 12 wherein the internal bore of the tubular grip element is defined by an inner wall, and wherein the inner wall of the tubular grip element includes a reduced-diameter reinforcing rib to resist collapse of the tubular grip element as a user rotates the tubular grip element to rotate the coupling nut relative to an equipment port.

21. The coaxial cable connector of claim 20 wherein the reinforcing rib is disposed generally proximate the central portion of the tubular grip element.

22. A coaxial cable connector comprising in combination:

a. a coaxial connector, the connector including a generally-cylindrical body for receiving a prepared end of a coaxial cable, and including a nut rotatably secured to the body for securing the connector onto a coaxial port, the nut having an axial length and including an outer surface; and

b. a tubular grip element having an outer surface and an internal bore, the tubular grip element having an axial length exceeding the axial length of the nut, the body of the connector being disposed inside the internal bore of the tubular grip element, the tubular grip element being axially-slidable, relative to the body of the connector, for being axially advanced to extend over, and non-rotatably engage, an outer surface portion of the nut, the outer surface of the tubular grip element providing a surface that can be grasped by the fingers of a user to facilitate tightening of the nut to a coaxial port;

wherein the internal bore of the tubular grip element is defined by an inner wall, and wherein the inner wall of the tubular grip element includes a reduced-diameter reinforcing rib to resist collapse of the tubular grip element as a user rotates the tubular grip element to rotate the coupling nut relative to an equipment port.
