Abstract

Provided is an optical fiber adapter. The optical fiber adapter includes a first adapter body, a shielding gate elastically hinged to a lower end portion of the first adapter body, and a second adapter body whose a lower end portion is inserted into a cavity of the first adapter body. An end surface of the lower end portion of the second adapter body extends downward to form extension posts and an engagement arm, the extension posts are pressed against two ends of a hinge shaft of the shielding gate, and the engagement arm is exposed outside the shielding gate and is engaged with an optical fiber connector joint inserted into a lower end portion of the first adapter body. This structural design can facilitate the installation and fixation of the shielding gate, and thus a better light-shielding and dust-proof effect can be achieved.
