ABSTRACT:
A fiber optic connector is provided which includes a free floating ferrule so as to reliably withstand significant side-pull forces. In other words, the fiber optic connector is designed such that the minimum rotational angle of the combination of the ferrule and the pin clamp within the connector housing is greater than the maximum rotational angle of the connector housing within an adapter. In order to permit the ferrule to be free floating, the fiber optic connector can provide increased clearance or spacing between the combination of the ferrule and the pin clamp and the connector housing. For example, the inner sidewalls of the forward end of the connector housing may have either a beveled or a stepped profile in longitudinal cross-section so as to provide additional clearance at the forwardmost portion of the ferrule. The combination of the rear end of the ferrule and the pin clamp can also have a beveled profile so as to provide clearance at the rearwardmost portion of the ferrule and pin clamp combination. Similarly, the inner sidewalls of the connector housing proximate the rear end of the connector housing can also be tapered at an angle of at least 2.degree. to provide additional clearance.
