Coaxial connector and coaxial cable connector assembly and related method
View Patent ↗A method of making a coaxial cable assembly is disclosed, the assembly comprising a coaxial cable and a connector, or connector termination, 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.
1. A method of making a coaxial cable assembly, the coaxial cable comprising an inner conductor, a dielectric surrounding the inner conductor, a braid surrounding the dielectric, and a protective layer surrounding the braid, the method comprising:
passing an end of a coaxial cable through an internal bore in a tubular shell, 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 a coupler is mounted on the post, and wherein the shell is axially spaced away from the first portion of the post, and the shell does not surround the first portion of the post;
moving the shell axially relative to the post and the cable, wherein at least part of the shell surrounds and contacts at least part of the post;
wherein, after the moving step, at least a portion of the braid is seized between the post and the shell and the shell limits axial movement of the coupler;
and wherein the method further comprises:
removing a portion of the protective layer, a portion of the braid, and a portion of the dielectric from the end of the coaxial cable to provide a prepared end of the cable, wherein the prepared end comprises: a protective layer cut edge; a protruding portion of the braid that protrudes a length X from the cut edge of the protective layer, a protruding portion of the dielectric that protrudes a length Y from the cut edge of the protective layer, and a protruding portion of the inner conductor that protrudes a length Z from the cut edge of the protective layer, wherein the ratio of X/Y is less than 1.
2. The method of claim 1 wherein the coupler is rotatably mounted on the post.
3. The method of claim 1 wherein, in the moving step, the shell and the post are press fit together.
4. The method of claim 1 , wherein after the moving step, part of the cable is sandwiched between the shell and the post.
5. The method of claim 1 wherein the protruding portion of the dielectric terminates in a dielectric cut edge, and the protruding portion of the inner conductor protrudes a length A from the dielectric cut edge.
6. The method of claim 5 wherein the length A is between 0.25 and 0.375 inch.
7. The method of claim 1 wherein the coaxial cable further comprises a foil layer disposed between the braid and the dielectric, wherein the removing step further comprises removing a portion of the foil layer, and wherein the prepared end further comprises a protruding portion of the foil layer that protrudes a length Y′ from the cut edge of the protective layer, wherein the length Y′ is less than or equal to the length Y.
8. The method of claim 1 further comprising lifting at least part of the protruding portion of the braid radially outwardly.
