Robust fiber connector
First Claim
1. A connector for use with robust optical fiber, said connector comprising:
- a housing member having a forward portion and a rear portion;
a barrel member having a ferrule mounted therein for connection to another component contained in said forward portion, said barrel member having a flange having a first outside diameter and a tubular portion extending rearwardly therefrom having a second outside diameter less than said first outside diameter;
a bore extending through said barrel member;
a stop member for limiting rearward movement of said barrel member within said housing to a distance less than that causing disconnection of said ferrule.

Abstract
A pull-proof optical fiber connector for use with robust optical fiber has a housing and a ferrule bearing barrel member therein having a first outside diameter over a front portion thereof and a second, lesser outside diameter rearward portion, and a bore extending therethrough forming an optical fiber passage.
The barrel member and, hence, the ferrule are rearwardly movable under axially pulling stress, and a stop member prevents further rearward movement prior to any disengagement of the ferrule with an associated ferrule or other apparatus. In one embodiment of the invention, the stop member is a fiber retention member having a front face and a bore extending therethrough of lesser diameter than the outside diameter of the second portion, thereby halting rearward movement when the end of the second portion butts against the front face of the cable retention member.
In another embodiment of the invention the stop member is the rear edge of a substantially rectangular opening in the housing, which functions to block a U-shaped retainer member which embraces the second portion of the barrel after allowable rearward movement under rearward axial stress.
