1. A fiber connector plug, comprising:
a fiber comprising a front end and a periphery;
a ferrule fastened to the front end;
a main housing that is sleeve-shaped and sleeved over the periphery, wherein the main housing comprises an outer surface and a sealing structure disposed on the outer surface, and wherein the sealing structure is configured to sealingly connect to an inner surface of a fiber adapter; and
a first locking structure disposed on the outer surface of the main housing such that the sealing structure is located between the first locking structure and the ferrule along an axial direction of the main housing, wherein the first locking structure is configured to fit a second locking structure on the fiber adapter to fasten the fiber connector plug to the fiber adapter, wherein the sealing structure is located between the first locking structure and the ferrule along an axial direction of the main housing, and wherein the sealing structure is configured to sealingly connect to an inner surface of the fiber adapter, and wherein the first locking structure comprises:
a sliding member slidably connected between a first position of the main housing and a second position of the main housing; and
a locking part fastened to the outer surface of the main housing and located between the sliding member and the ferrule along the axial direction; and
wherein the sliding member is configured to:
fit the locking part and to jointly lock to the second locking structure when the sliding member is located in the first position; and
unlock the locking part from the second locking structure when the sliding member is located in the second position.
