Abstract
A fiber optic ferrule and a fiber optic connector housing make contact only along two sides of the fiber optic ferrule when in an unmated condition. One of the fiber optic ferrule and the fiber optic connector housing have been modified such that only two of the surfaces engage one another. The shoulders can be shortened, lengthened, or have a projection added to the current surfaces.
Claims16
A combination of a fiber optic ferrule and a fiber optic connector housing comprising:
- a fiber optic ferrule having a first pair of shoulders on a first pair of opposite sides of the fiber optic ferrule lying in a first plane and a second pair of shoulders on a second pair of opposite sides of the fiber optic ferrule lying in a second plane;
- and
- a fiber optic connector housing comprising:
- a main body having an interior surface defining a main opening extending through the main body to receive at least a portion of the fiber optic ferrule;
- a third pair of shoulders extending into the main opening from the interior surface, the third pair of shoulders disposed on opposite sides of the main opening and lying in a third plane;
- and
- a fourth pair of shoulders extending into the main opening from the interior surface, the fourth pair of shoulders disposed on a second pair of opposing sides of the main opening and lying in a fourth plane,
- wherein at least one pair of the first and second planes and the third and fourth planes are spaced apart from one another and wherein the interior surface is tapered such that the main opening is smaller at the third and fourth shoulders than at a front end of the fiber optic connector housing.

A fiber optic ferrule comprising:
- a first pair of shoulders on a first pair of opposite sides of the fiber optic ferrule lying in a first plane and facing in a forward direction;
- and
- a second pair of shoulders on a second pair of opposite sides of the fiber optic ferrule lying in a second plane and also facing in a forward direction, the first and second planes being parallel and spaced apart from one another, wherein the fiber optic ferrule has a front portion and an enlarged rear portion enlarged relative to the front portion, the first pair of shoulders dividing the front portion from the enlarged rear portion of the fiber optic ferrule on the first pair of opposite sides of the fiber optic ferrule and the second pair of shoulders dividing the front portion from the enlarged rear portion on the second pair of opposite shoulders.
A fiber optic connector inner housing comprising:
- a main body having an exterior surface and an interior surface, the main body extending between a front end and a rear end;
- a main opening extending through the main body between the front and rear ends, the main opening at least partially defined by the interior surface of the main body and to receive therein from the rear end at least a portion of fiber optic ferrule;
- a first pair of shoulders extending into the main opening from the interior surface, the first pair of shoulders disposed on opposite sides of the main opening and lying in a first plane;
- and
- a second pair of shoulders extending into the main opening from the interior surface, the second pair of shoulders disposed on a second pair of opposing sides of the main opening and lying in a second plane, the first and second planes being parallel and spaced apart from one another and wherein the interior surface is tapered such that the main opening is smaller at the first and second pair of shoulders than at the front end of the main body.
