Optical fiber connector and optical fiber adapter

An optical fiber connector comprising:

• a casing body that includes
• a casing wall portion defining an accommodating space therein, and
• an engaging portion extending inclinedly from said casing wall portion away from said accommodating space, being flexible, extending substantially along a longitudinal axis, and having a distal end that is distal from and movable relative to said casing wall portion along a height axis perpendicular to the longitudinal axis;
• a housing that includes two seat members removably mounted to said casing body and detachably connected to each other, each of said seat members having
• a side wall portion that extends along the longitudinal axis,
• an end wall portion that extends from said side wall portion along a width axis perpendicular to the longitudinal axis and the height axis, and
• a connecting wall portion that extends from said end wall portion along the height axis and that abuts against said side wall portion of another one of said seat members, said side wall portions, said end wall portions and said connecting wall portions of said seat members cooperatively defining two accommodating grooves that extend in a direction of the longitudinal axis, said side wall portions being spaced apart from each other along the width axis and defining a disposition groove extending along the longitudinal axis;
• two resilient members that are disposed respectively in said accommodating grooves and that are respectively located at two opposite sides of said disposition groove along the height axis;
• a tail sleeve that includes
• a receiving portion mounted to said seat members, and slidable along the longitudinal axis, and
• a cover portion extending from said receiving portion along the longitudinal axis in a direction away from said casing body;
• and
• an auxiliary member that includes
• a base portion mounted on said tail sleeve, and
• a drive portion extending from said base portion along the longitudinal axis and driving movement of said distal end of said engaging portion, said auxiliary member being co-movable with said tail sleeve when said tail sleeve is pulled away from said casing body along the longitudinal axis such that said drive portion drives said distal end of said engaging portion to move toward said casing wall portion along the height axis.
