    Abstract: An optical fiber connector includes a connector housing module, a fastener, a linkage member, and a pull handle. The connector housing module includes at least one clip arm, and the connector housing module is adapted to be inserted into a target object and buckled to the target object by the clip arm. The fastener buckles the connector housing module. The linkage member is pivotally connected to the fastener and movably abuts against the clip arm. The pull handle movably passes between the fastener and the linkage member to be connected to the linkage member. When the connector housing module is inserted into the target object, the pull handle is adapted to be forced to drive the linkage member to pivot relative to the fastener and press against the clip arm, so as to remove a buckling state between the clip arm and the target object and pull the connector housing module out of the target object.

The multi-fiber connector (40) also includes a ferrule (10a, 10b) with optical contacts (20a, 20b) at a front end (14a, 14b). The ferrule (10a, 10b) is spring biased toward the front end (14a, 14b) of the connector body (44). The ferrule (10a, 10b) has a pair of alignment pin openings (30a, 30b) extending into the ferrule from a front end (14a, 14b). The ferrule (10b) also has a pair of alignment pins (22) mounted within the alignment pin openings (30a, 30b). The base ends of the alignment pins (22) have a different transverse cross-sectional shape than the alignment pin openings (30a, 30b). This difference in transverse cross-sectional shapes allows the alignment pins to pivot relative to the ferrule along a major axis of the ferrule.
