Abstract
A strain relief system for the backside of a fiber optic connector has a controlled bend radius defined by the formula R=[(W+t).sup.2 /2(1-cos .phi.)].sup.1/2, where W is the rib thickness, t is the width of spaces between the ribs, and .phi. is an angle defined by comers of the ribs which engage each other at the minimum bending radius and a pivot point about which the ribs pivot relative to each other.
Claims14
An optical fiber connector, comprising:
- a boot which includes:
- a generally cylindrical main section having a principal longitudinal axis;
- a plurality of ribs in the generally cylindrical section, said ribs having a width W in the direction of the longitudinal axis defined by a plurality of cuts having a width t in the direction of the longitudinal axis;
- said boot being bendable through an angle .phi. about pivot points defined by respective intersections of the longitudinal axis with bisectors of said cuts such that as said boot is bent, edges of said ribs engage each other,
- wherein dimensions W, t, and .phi., are selected to provide a predetermined minimum bending radius;
- and
- means including a connector member and a crimp ferrule between which an optical fiber jacket portion is secured.
