Right angle strain relief for optical fiber connector

Claim 1

An optical connector comprising; an alignment ferrule having a central passage for aligning an optical fiber of an optical cable; molded, flexible curved rubber boot having a cylindrical axial bore sized for receiving the optical fiber cable therewithin; the alignment ferrule having a central passage for aligning an optical fiber, and having a radially enlarged collar and a circumferential groove spaced from a rear transverse face of the collar, and having a rear circumferential groove and a flange; a snap ring mounted in the groove; a coupling nut moveable axially over the ferrule and having a transverse inner flange encircling the alignment ferrule forwardly of the snap ring; a spring for compression directly in engagement against the rear transverse face of the collar and for compression against the inner flange; a clearance between the coupling nut and the collar in which the collar is moveable during retraction of the collar into the coupling nut to compress the spring; said boot having a cylindrical axial bore sized for receiving the optical fiber cable therewithin; an annular flange and a recess within axial bore at a front end of said boot complementarily fitted to said rear circumferential groove and said flange of said ferrule; and said boot having a curvature along a curved line extending the cable 90 degrees to the plane of connection between said ferrule and said boot.
