Patent ID: 7178988

Claim:
A method for assembling an optical connector plug adapted to be attached to or detached from either an SC type or an FC type optical connector adapter, said optical connector plug comprising: a plug frame internally supporting a ferrule secured to an end of an optical fiber such that said ferrule can rotate around the axial center of said ferrule; and a plug holder rotatably supported by said plug frame around said axial center of the ferrule, said plug holder being non-rotatably secured to said ferrule around said axial center of the ferrule, said plug holder having a holding part exposed outside of said plug frame, so that when assembling said optical connector plug, said ferrule is adapted to be rotated to a desired rotation angle in relation to said plug frame, said assembling method comprising the steps of: passing an optical fiber through a plug holder; inserting the end of said optical fiber in a ferrule and securing the end of said optical fiber in said ferrule; grinding the end face of said ferrule together with the end face of said optical fiber; and after grinding, inserting said ferrule and said plug holder into a plug frame, thereby assembling the main body of said plug; inserting the plug main body in an alignment adapter, then, with the optical fiber supported by the plug main body being optically connected to the optical fiber of the alignment adapter, aligning the optical fiber of the plug main body by non-incrementally rotating said plug holder in relation to said plug frame; and after aligning, securing said plug holder to the plug frame to be non-rotatable with respect thereto.
