Patent ID: 8632259

Claim:
An optical fiber connector for fixing an optical fiber comprising: an inner housing; and a fixing module sleeved in the inner housing, the fixing module comprising: a fixing mechanism comprising a supporting member and a clamping member cooperatively forming a cylindrical structure to fix the optical fiber inserted into the fixing module, the supporting member comprising a first fixing portion axially defining a first restricting groove, a first fixing end and a second fixing end at two opposite ends of the first fixing portion, the clamping member comprising a second fixing portion axially defining two sliding grooves on two borders of the second fixing portion; a locking member sleeved on the fixing mechanism, the locking member comprising an annular main body and two sliding protrusions formed at the inner wall of the annular main body, the sliding protrusions are opposite to each other, and the two sliding protrusions sliding along the two sliding grooves respectively; a position member fixed at the first fixing end of the supporting member; and an elastic member sleeved on the fixing mechanism with an end of the elastic member resisting with the position member and the other end of the elastic member resisting with the locking member, wherein the diameter of the fixing mechanism gradually decreases from the second fixing end to the first fixing end, and the radial depth of the two sliding grooves gradually decrease from the second fixing end to the first fixing end.
