TOWING ASSEMBLY, FIBER OPTIC CONNECTOR AND METHODS OF PRODUCING AND ASSEMBLING THE SAME
First Claim
1. A fiber optic connector comprising:
- a housing; and
an integrated ferrule assembly adapted to be inserted into or pulled out of the housing in a manner of a single piece;
wherein N positioning keys are formed on an outer periphery of a ferrule tail seat of the ferrule assembly, wherein N is an integer equal to or greater than two, the N positioning keys are spaced each other at an equal angle around the outer periphery of the ferrule tail seat, and one of the N positioning keys corresponding to an eccentric orientation of an optical fiber fixed in the ferrule assembly is cut off to form a cutting portion;
(N−
1) positioning slots, which correspond to (N−
1) positioning keys on the ferrule tail seat respectively, are formed in the housing, and there is no positioning slots formed in a part of the housing corresponding to the cutting portion, such that the integrated ferrule assembly is allowed to be inserted into the housing only when the (N−
1) positioning keys are aligned with the (N−
1) positioning slots, respectively.

Abstract
A fiber optic connector includes: a housing and an integrated ferrule assembly. N positioning keys are formed on an outer periphery of a ferrule tail seat of the ferrule, wherein N is an integer equal to or greater than two, the N positioning keys are spaced at an equal angle around the outer periphery of the ferrule tail seat, and one of the N positioning keys corresponding to an eccentric orientation of an optical fiber secured in the ferrule is cut out to form a cutting portion; (N−1) positioning slots, which correspond to (N−1) positioning keys on the ferrule tail seat, respectively, are formed in the housing, and there is no positioning slot formed in a part of the housing corresponding to the cutting portion, such that the integrated ferrule assembly may be inserted into the housing only when the N−1 positioning keys are aligned with the (N−1) positioning slots respectively. Thus, the fiber optic connector is adapted to be assembled and detached in the field, preventing effectively the ferrule assembly of the fiber optic connector from being inserting into the housing thereof in an incorrect orientation angle.

9. A towing assembly comprising:
-
an integrated ferrule assembly comprising a ferrule body, a ferrule tail seat, a spring, a spring seat, a crimp ring, a shrinkable tube, a boot, an optical cable and a dust cap which are assembled; and a towing portion sleeved hermetically on the spring seat of the integrated ferrule assembly; wherein, internal threads are formed on an inner wall of the towing portion and external threads are formed on an outer wall of the spring seat, and the towing portion is threaded to the spring seat; a groove is formed on the outer wall of the spring seat and an elastic seal ring is disposed in the groove, the inner wall of the towing portion is provided to press against the elastic seal ring when the towing portion is sleeved on the spring seat, so that a fitting interface between the towing portion and the integrated ferrule assembly is sealed; and N positioning keys are formed on an outer periphery of the ferrule tail seat, wherein N is an integer equal to or greater than two, the N positioning keys are arranged to be spaced at an equal angle around the outer periphery of the ferrule tail seat, and one of the N positioning keys corresponding to an eccentric orientation of an optical fiber secured in the ferrule is cut off to form a cutting portion. - View Dependent Claims (10, 11, 12, 13, 14)
