Optical fiber connector

An optical fiber connector adapted for connection with an adapter, the adapter being located in front of said optical fiber connector, and having an inner surrounding surface that defines a connecting hole, and a coupling groove that is formed in the inner surrounding surface, said optical fiber connector comprising:

• a main body unit extending in a front-rear direction, and including two side plates that are spaced apart from each other, and two connecting plates that are connected between said side plates, each of said connecting plates having a guiding groove that extends in the front-rear direction, and two position limiting portions that respectively protrude from two walls respectively defining two sides of said guiding groove toward each other in a transverse direction which is perpendicular to the front-rear direction;
• a sleeve unit sleeved onto said main body unit, movable relative to said main body unit in the front-rear direction, and having two connecting walls that are spaced apart from each other, and that extend in the front-rear direction, each of said connecting walls having an inner surface that faces toward said main body unit, a slide groove that is formed in said inner surface, and that is communicated with a respective one of said guiding grooves of said main body unit, and two guiding block portions that respectively protrude from two walls respectively defining two sides of said slide groove toward each other in the transverse direction, each of said slide grooves cooperating with a corresponding one of said guiding grooves to form a slide space;
• and
• a coupling unit including two coupling members that are respectively movable in said slide spaces in the front-rear direction, each of said coupling members having a base portion, two resilient arm portions that are spaced apart from each other in the transverse direction, and that extend rearwardly from said base portion, and two first protruding block portions that respectively protrude from said resilient arm portions in the transverse direction and away from each other, said base portion and said resilient arm portions being formed as one piece, each of said coupling members being movable between a non-working position where said base portion of a corresponding one of said coupling members is concealed within said sleeve unit, and where said first protruding block portions are disposed behind said position limiting portions of said main body unit, and a working position where said first protruding block portions are disposed in front of said position limiting portions of said main body unit, and where at least a portion of said base portion of the corresponding one of said coupling members is exposed outwardly from said sleeve unit, and is adapted to engage the coupling groove of the adapter;
• wherein said sleeve unit is configured to be movable rearwardly on said main body unit to press said first protruding block portions of each of said coupling members of said coupling unit toward each other, so as to allow said first protruding block portions to pass past said position limiting portions of said main body unit, thereby allowing for movement of each of said coupling members between the non-working position and the working position.
