Abstract
A crimp band is provided with a first portion configured to be received over a rear portion of a connector body. The first portion is shaped to have an interference fit with the rear portion of the connector body when the first portion is received thereon. Methods of forming a cable assembly with such a crimp band involve initially securing a cable to the connector with the crimp band, completing at least one additional processing step with the cable initially secured by the crimp band, completing a re-work of the additional processing step(s) with the crimp band removed from the connector, and later permanently securing the cable to the connector with the crimp band.
Claims20
A method of making a fiber optic cable assembly from a cable and a connector, wherein the cable includes a cable jacket, at least one optical fiber carried within the cable jacket, and aramid yarn carried within the cable jacket, and wherein the connector includes a ferrule and a connector body, the method comprising:
- positioning a crimp band over an end portion of the cable jacket;
- terminating the at least one optical fiber with the ferrule after positioning the crimp band, wherein the at least one optical fiber extends from an end of the cable jacket before the terminating;
- assembling the connector body with the ferrule before or after the terminating step;
- positioning at least some length of aramid yarn that extends from the end of the cable jacket over a rear portion of the connector body;
- moving the crimp band over the rear portion of the connector body after the preceding steps such that the at least some length of the aramid yarn is positioned between the crimp band and the rear portion of the connector body, wherein the crimp band is configured to have an interference fit with the rear portion of the connector body without being crimped such that the moving results in the crimp band securing the at least some length of aramid yarn to the rear portion of the connector body;
- performing one or more additional processing steps while the at least some length of aramid yarn remains secured to the rear portion of the connector body by the interference fit with the crimp band;
- determining that a re-work of the assembling step or any of the one or more additional processing steps is needed before crimping the crimp band over the rear portion of the connector body;
- removing the crimp band from the rear portion of the connector body and performing the re-work;
- and
- crimping the crimp band over the rear portion of the connector body after performing the re-work.
A method of making a fiber optic cable assembly from a cable and a connector, wherein the cable includes a cable jacket, at least one optical fiber carried within the cable jacket, and aramid yarn carried within the cable jacket, and wherein the connector includes a ferrule and a connector body, the method comprising:
- positioning a crimp band over an end portion of the cable jacket;
- securing the at least one optical fiber to the ferrule after positioning the crimp band, wherein the at least one optical fiber extends from an end of the cable jacket before the securing;
- assembling the connector body with the ferrule before or after the securing step;
- positioning at least some length of aramid yarn that extends from the end of the cable jacket over a rear portion of the connector body;
- moving the crimp band over the rear portion of the connector body after the preceding steps such that the at least some length of aramid yarn is positioned between the crimp band and the rear portion of the connector body, wherein the crimp band is configured to have an interference fit with the rear portion of the connector body without being crimped such that the moving results in the crimp band securing the at least some length of aramid yarn to the rear portion of the connector body;
- inspecting the connector while the at least some length of aramid yarn remains secured to the rear portion of the connector body by the interference fit with the crimp band;
- identifying that one or more additional processing steps or assembly steps is required based on the inspecting;
- removing the crimp band from the rear portion of the connector body and performing the one or more additional processing steps or assembly steps that were identified;
- and
- crimping the crimp band over the rear portion of the connector body after performing the one or more additional processing steps or assembly steps that were identified.
A method of making a telecommunications cable assembly from a cable and a connector, wherein the cable carries at least one signal conductor, the method comprising:
- positioning a crimp band over a cable jacket of the cable;
- terminating the at least one signal conductor with the connector, wherein the crimp band is spaced from the connector during the terminating, and wherein an end section of the at least one signal conductor extends from an end of the cable jacket before the terminating;
- positioning at least some amount of strength members of the cable over a rear portion of the connector;
- moving at least a first portion of the crimp band over the rear portion of the connector after the terminating step and after the step of positioning at least some amount of the strength members, wherein the first portion of the crimp band is configured to have an interference fit with the rear portion of the connector without being crimped such that the moving results in the crimp band initially securing the at least some amount of the strength members to the connector;
- performing one or more additional processing steps while the crimp band remains uncrimped and the cable remains initially secured to the connector by the crimp band;
- determining that a re-work of at least one of the one or more processing steps is required;
- removing the crimp band from the connector so that the cable is no longer initially secured to the connector;
- performing the re-work;
- and
- permanently securing the cable to the connector using the crimp band, wherein the crimp band is crimped to permanently secure the cable to the connector.
