Abstract

An electrical connector for use with coaxial cables includes a deformable cylindrical casing and a slidably engaged shell.

Claims

1. A coaxial cable connector comprising:

a cylindrical casing has a first end for receiving a coaxial cable and a second end that receives a core tube;

the core tube engages a first fastener operable to fasten the connector to a mating second fastener;

a shell has first and second open ends;

in a first configuration before a coaxial cable is fixed to the connector, the casing extends through the shell;

the casing and the shell are dimensioned such that the shell is operative to radially press and radially deform the casing when the shell is moved from its position in the first configuration toward the casing first end; and

,

the deformed casing is operative to pinch portions of a coaxial cable located between the cylindrical casing and the core tube.

2. The coaxial cable connector of claim 1 further comprising:

a central casing section having a tapered abutment face; and

,

the shell operable in concert with the tapered abutment face to cause casing radial deformation.

3. The coaxial cable connector of claim 2 further comprising:

first and second casing sections having first and second wall thicknesses;

the first wall thickness being greater than the second wall thickness;

the central casing section located between the first and second cylindrical casing sections; and

,

the casing deformation including deformation of the first casing section and excluding deformation of the second casing section.

4. The coaxial cable connector of claim 2 further comprising a shell wall taper for coacting with the casing tapered abutment face.

5. The coaxial cable connector of claim 2 wherein the casing is made of a deformable plastic material.

6. A coaxial cable connector comprising:

a cylindrical casing has a first end for receiving a coaxial cable and a second end receiving a core tube;

the core tube is coupled to a fastener;

a shell is located in an initial position between the first and second ends of the cylindrical casing;

the shell slidably engages the cylindrical casing;

movement of the shell from the initial position toward the cylindrical casing first end is operable to radially compress a deformable portion of the cylindrical casing; and

,

the deformed cylindrical casing is operable to fix portions of a coaxial cable passing between the cylindrical casing and the core tube.

7. The coaxial cable connector or claim 6 wherein the casing includes a tapered abutment face operable to coact with the shell.

8. A method of making a coaxial cable connector comprising the steps of:

providing a cylindrical casing having a deformation region located between non-deformable opposed ends of the casing;

slidably engaging a shell with the casing between the casing opposed ends; and

,

dimensioning the casing and the shell such that movement of the shell over the deformation region is operable to fix portions of a coaxial cable passing between the casing and a core tube.

9. The method of claim 8 wherein the opposed ends include a cable entry end and shell movement fixing the cable is shell movement toward the cable entry end.

10. The method of claim 9 wherein the deformation region includes an outside annular flange located between a tapered abutment face and a locating groove.

11. The method of claim 10 wherein shell movement toward the cable entry end is operative to deform the tapered abutment face, the outside annular flange and the locating groove.
