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.
Claims14
A fiber optic ferrule comprising:
- a first pair of opposing short sides;
- a second pair of opposing long sides that have a length greater than the opposing short sides, each of the second pair of opposing long sides joined to each of the first pair of opposing short sides;
- and
- a forward facing surface provided on each of the second pair of long sides, the forward facing surface configured to engage an interior surface of a connector housing, wherein there is a clearance between the first pair of opposing short sides of the fiber optic ferrule and the interior surface of the connector housing in an unmated configuration of a fiber optic connector, the clearance of the fiber optic ferrule with the connector housing extending all along the first pair of opposing short sides of the fiber optic ferrule from an end face thereof to a rearmost end of the fiber optic ferrule and the second pair of long sides engage the interior surface of the connector housing when the fiber optic ferrule is inserted in the connector housing.
