A strain relief system for a fiber optic connector includes a boot made up of two halves, the halves being fitted together by press-fit pins supported by a flange which also serves increase the rigidity of the boot. The boot is held in place on the cable by using internal ribs at an distal from the connector. The force required to make the ribs hold the boot in place is provided by stretching a standard elastomeric boot over the outer diameter of the section containing the ribs. The system further incorporates a support clip at the connector end to assist the two halves in staying together and further resist lateral bending moments. The outer profile of the support clip can be adapted to fit a variety of different connector configurations, and thus the support clip also serves as an adapter for the strain relief system.

Strain relief system for a fiber optic connector

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.
