Abstract

A crimp type F-Connector wherein the crimp required for easy installation reduced while affording reliable cable retention. A wide range of cable sizes are accommodated by one connector which is configured to provide adequate sealing and mechanical strength in the connector while facilitating optimized radial deformation for providing reliable retention and a reliable mechanical and electrical interface with the coaxial cable upon which it is crimped. The connector includes a crimping portion including a sleeve that has a plurality of ribs or external annular protrusions which are dimensioned to enhance rigidity and mechanical strength. The ribs are of equal diameters when uncrimped and are "flat" crimped to maximize the cable area against which crimp forces are applied. An innermost rib is proximate to a support wall and separated by an exaggerated spacing to reduce crimp forces experienced when installing the connector onto the cable.

Dependent claims

A coaxial cable end connector comprising:

an outer sleeve having an outer surface with an outer sleeve outer diameter and an outer sleeve inner surface with an outer sleeve inner diameter, said outer sleeve having a cable receiving end and a post connection end,
said outer sleeve including a support portion adjacent the post connection end, said support portion having an outer surface and having a support portion wall extending between said support portion outer surface and said outer sleeve outer surface,
said outer sleeve having a plurality of axially spaced ribs extending annularly from said outer surface of said outer sleeve, each of said plurality of axially spaced ribs having respective rib diameters, said plurality of axially spaced ribs including an outermost rib adjacent the cable receiving end of said outer sleeve and an innermost rib having an inner edge adjacent to and spaced from said support portion wall, one of said plurality of ribs having a largest rib diameter,
said outer sleeve having a first sleeve portion of a first length extending from said support portion wall to said inner edge of said innermost rib and a second sleeve portion of a second length extending from said support portion wall to said cable receiving end of said outer sleeve;
the difference between said largest rib diameter and said outer sleeve outer diameter divided by said largest rib diameter being a ratio of at least 0.10;
said first length divided by said second length being a ratio of at least 0.25.
