Patent Images
1. A connector for crimped attachment to a coaxial cable having a central conductor disposed within a dielectric sleeve, a braided sheath surrounding the sleeve and a jacket encircling the braided sheath, said connector comprising in combination:
- a) a hollow body for penetrable insertion intermediate the sleeve and the braided sheath to locate the conductor and sleeve within said body;
b) a ferrule attached to and extending from said body for enveloping the coaxial cable;
c) said body and said ferrule defining in combination a cylindrical slot for receiving the braided sheath and the jacket; and
d) at least one annular ridge encircling said ferrule, each of said ridges having a modified hexagonal perimeter defining three pairs of opposed planar surfaces and arcuate surfaces interconnecting adjacent ones of said planar surfaces prior to crimped attachment of said connector to the coaxial cable.

Abstract
A crimp connector for attachment to a coaxial cable by use of a conventional crimping tool includes a plurality of annular ridges to be crimped, which ridges define a modified hexagonal perimeter having three pairs of opposed planar surfaces and curved surfaces interconnecting adjacent ones of the planar surfaces. A method for crimping resulting in migration of the material of the ridges to maintain a rounded surface about the coaxial cable is disclosed.

15. A method for attaching a connector to the terminal end of a coaxial cable having a central conductor disposed within a dielectric sleeve, a braided sheath surrounding the sleeve and a jacket encircling the braided sheath, said method comprising the steps of:
-
a) inserting a hollow body of the connector intermediate the sleeve and the braided sheath to locate the conductor and the sleeve within the body and to position to coaxial cable within an hollow circular interior of a ferrule attached to and extending from the body; b) further inserting the braided sheath and the jacket within a cylindrical slot formed by the body and the ferrule; c) compressing between opposed jaws of a crimp tool defining a hexagon at least one ridge encircling the ferrule, which ridge has a modified hexagonal perimeter defining three pairs of parallel planar surfaces and arcuate surfaces interconnecting adjacent ones of the planar surfaces, to secure the ferrule with the encircled coaxial cable; and d) said step of compressing including the step of urging migration of material of the ridge into the corners of the hexagon defined by the crimp tool to maintain the interior surface of the ferrule generally circular to enhance formation of a seal by the ferrule about the coaxial cable. - View Dependent Claims (16, 17, 18, 19)

20. In a connector for terminating the terminal end of a coaxial cable by attaching the connector with a hexagonal crimp delivered by a conventional crimping tool, which connector includes a rotatably attached nut, a body for penetrably engaging the coaxial connector and a ferrule extending from the body and defining a generally circular interior for encircling and compressively engaging the coaxial cable, the improvement comprising in combination:
- at least one ridge encircling the ferrule proximate one end of the ferrule for crimping by the crimp tool, each of said ridges having a modified hexagonal perimeter defining three pairs of parallel planar surfaces and arcuate curved surfaces interconnecting adjacent ones of the planar surfaces to accommodate migration of material of said ridges upon crimping of said ridges about the coaxial cable to permit maintenance of a generally circular interior, surface of the ferrule.
