Abstract

A method of making a coaxial cable assembly is disclosed, the assembly comprising a coaxial cable and a connector, or connector termination, on at least one end of the cable. A connector, comprised of connector components, is also disclosed. The method comprises placing connector components into contact with the cable before the connector components are assembled into a connector. The connector is assembled simultaneously with securing the connector to the cable to make a coaxial cable assembly. A method of preparing coaxial cable in a manner suitable for making coaxial cable assemblies is also disclosed. The coaxial cable assembly can be a jumper, or a lead.

Claims

1. A method of making a coaxial cable assembly, the method comprising:

passing an end of a coaxial cable through an internal bore in a tubular shell and an internal bore of a coupler, wherein the coaxial cable has a longitudinal axis;

inserting a first portion of a tubular post axially into the end of the coaxial cable, wherein the tubular shell and the coupler are axially spaced away from the first portion of the post, and the shell does not surround the first portion of the post; and

after the inserting step, moving the tubular shell and the coupler axially relative to the post and the coaxial cable, wherein at least part of the tubular shell surrounds at least part of the tubular post and wherein at least a portion of the coupler surrounds at least a part of the tubular shell and the coaxial cable.

2. The method of claim 1, wherein the coupler has a threaded internal surface.

3. The method of claim 1, wherein the tubular shell limits axial movement of the coupler.

4. The method of claim 1, wherein the tubular shell limits axial movement of the coupler in two directions.

5. The method of claim 1, wherein the tubular post limits axial movement of the coupler.

6. The method of claim 1, wherein, after the moving step, part of the coaxial cable is sandwiched between the shell and the post.

7. The method of claim 1, wherein, in the moving step, a portion of the tubular shell is pushed outward to engage the coupler by the coaxial cable and tubular post.

8. The method of claim 1, wherein at least part of the tubular shell is disposed in the internal bore of the coupler prior to passing the coaxial cable through the internal bore of the tubular shell.

9. A method of making a coaxial cable assembly, the method comprising:

passing an end of a coaxial cable through an internal bore in a tubular shell and an internal bore of a coupler;

inserting a tubular post into the end of the coaxial cable, wherein the tubular shell and the coupler are spaced away from the post, and the shell and the coupler does not surround the post; and

after the inserting step, moving the shell and the post together sufficient to surround at least part of the post with at least part of the shell.

10. The method of claim 9, further comprising the step of moving the coupler towards the end of the coaxial cable.

11. The method of claim 9, wherein the moving step further comprises bringing the shell into mechanical contact with the post.

12. The method of claim 11, wherein, in the moving step, at least part of the raised portion of the cable is disposed between the at least part of the post and the at least part of the shell.

13. The method of claim 9, wherein, after the moving step, the shell limits movement of the coupler.

14. The method of claim 9, further comprising, before the inserting step, mounting a coupler on the shell.

15. The method of claim 14 wherein the coupler is rotatably mounted on the shell.

16. A method of making a coaxial cable assembly, the method comprising:

providing a length of coaxial cable having an end, the cable comprising an inner conductor and outer components surrounding the inner conductor, the outer components comprising a first outer component surrounded by a second outer component;

providing a tubular shell, a tubular post, and a coupler;

inserting the end of the cable into a first end of the tubular shell;

inserting a back end of the tubular post into the end of the cable, wherein the back end is wedged between the first outer component and the second outer component of the cable;

moving the tubular shell axially toward a front end of the post sufficient for the shell to surround at least a portion of the tubular post, thereby causing the shell and the post to transmit a compressive force to the second outer component sufficient to secure the shell and the post onto the cable.

17. The method of claim 16, wherein the moving step causes a portion of the tubular shell to be moved radially outward and engage a portion of the coupler.

18. A coaxial connector comprising:

a tubular shell, the tubular shell having an internal bore to receive a coaxial cable therethrough and a lip at a front end;

a tubular post having an internal bore to receive at least a portion of the coaxial cable, the tubular post also having an outer surface and an annular collar configured to engage the front end of the tubular shell; and

a coupler having an internal bore to receive the coaxial cable and at least a portion of the tubular shell therein, the internal bore having an annular recess;

wherein in a fully compressed position the lip on the tubular shell is deflected radially outward and into the annular recess of the coupler by contact between the tubular shell and the tubular post and the tubular shell is press fit onto the tubular post.

19. The coaxial connector of claim 18, wherein the coupler is rotatable around the tubular shell and the tubular post.

20. The coaxial connector of claim 18, wherein the tubular shell has an outer surface, an annular recess in the outer surface, and wherein a portion of the coupler is disposed in the annular recess of the tubular shell sufficient to limit the coupler from moving in a rearward direction.
