  • Patent number: 5217393
    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.
