Abstract
Abstract A cable connector is comprised of at least a first piece including a ferrule having serrations for mechanically connecting with different parts of a coaxial cable, a mandrel and a closing collar. A second piece of the connector is comprised of an entry body including a pin terminal, a support insulator and an actuator. Additionally, the connector provides a visual determination of the complete mating of one piece of the connector to the other.
