Method for standardizing coaxial cable jacket diameters
View Patent ↗A method of preparing the end of a coaxial cable for insertion within a coaxial cable connector involves stripping the cable jacket from the end of the cable, and reducing the outer diameter of the cable jacket portion lying adjacent the stripped portion of the jacket to a relatively constant reduced diameter. The reduced diameter portion of the cable jacket can then be reliably sealed to the back nut of the coaxial connector by an O-ring. A related preparation tool is disclosed for simultaneously stripping the cable jacket from the end of the cable, and reducing the outer diameter of the cable jacket portion lying adjacent the stripped portion, as the tool is rotated about the end of the coaxial cable. The tool may also serve to remove a portion of the outer conductor, as well as a coring member to remove dielectric surrounding the inner conductor of the cable.
1. A method of preparing an end of a coaxial cable, the coaxial cable including a inner conductor, an outer conductor, a dielectric therebetween, and a protective outer cable jacket, wherein said method improves the seal between the cable jacket and a coaxial connector, said method comprising the steps of:
a. stripping the cable jacket entirely off of the end of the outer conductor for a first predetermined length, said first predetermined length extending between the end of the coaxial cable and a first point;
b. removing an outer portion of the cable jacket while maintaining an inner portion of the cable jacket for a second predetermined length, thereby reducing the outer diameter of a portion of the cable jacket for said second predetermined length, said second predetermined length extending from the first point to a second point;
c. said step of reducing the outer diameter of the cable jacket including the step of making the outer diameter of said cable jacket relatively constant and smoother over said second predetermined length;
d. inserting the end of the coaxial cable into a coaxial connector; and
e. compressing a seal between the coaxial connector and a point on the cable jacket located along said second predetermined length.
2. The method of claim 1 including the further step of removing a portion of the outer conductor over a third predetermined length that is shorter than said first predetermined length to help expose the inner conductor.
3. The method of claim 1 including the further step of removing a portion of the dielectric covering the inner conductor over a third predetermined length that is shorter than said first predetermined length to help expose the inner conductor.
4. The method of claim 1 wherein the step of compressing a seal includes the steps of compressing a seal between a back nut of the coaxial connector and a point on the cable jacket located along said second predetermined length.
