Crimping tool system for optical fiber cables

U.S. Patent Number: 5274903

Abstract: A crimping tool system is provided for compressing a connector component onto an optical fiber cable, wherein the component includes an open end into which the cable is inserted. A tool includes a pair of jaws relatively movable toward and away from each other. Each jaw includes a first stage recessed surface area combining with the first stage recessed surface area of the other jaw to define a first stage crimping cavity sized to compress the cable sufficiently to ensure that the cable is insertable into the open end of the connector component. Each jaw includes a second stage recessed surface area combining with the second stage recessed surface area of the other jaw to define a second stage crimping cavity sized to compress the connector component onto the cable. The second stage recessed surface areas have protrusions for indenting the connector component and driving portions of the component against the cable. A rigid retention insert member surrounds the optical fiber of the cable to project the fiber, and the insert member is positionable inside an outer jacket of the cable to provide a rigid backing for the outer jacket when the connector component is crimped thereon.
