An insert core is installed in the installation groove. A first check portion is provided at the end of the insert core. A second check portion cooperating with the first check portion is provided on the inner wall of the main body housing. A blocking portion is provided on the side wall of the insert core. A spring is sleeved outside the insert core. Two ends of the spring are respectively in contact with the blocking portion and the second check portion. An optical fiber is inserted and installed in the tail sleeve. The optical fiber includes a core, aramid wrapped outside the core, and an epidermis wrapped outside the aramid. The core of the optical fiber is embedded and installed in the insert core.

[0006] Preferably, an external thread is provided on the outer side wall of the middle part of the main body housing, and an internal thread meshing with the external thread is provided on the inner wall of the tail sleeve.

[0007] Preferably, one end of the insert core extends outside the main body housing.

[0008] Preferably, the inner wall of one end of the insert core is conical.

[0009] Preferably, a chamfer is provided at the other end of the insert core.

[0010] Compared with the related technology, the utility model provided has the following beneficial effects:

[0011] Through the cooperation of the second check portion and the first check portion, the insert core is prevented from detaching from the main body housing.

[0012] An external thread is provided on the outer side wall of the middle part of the main body housing, and an internal thread meshing with the external thread is provided on the inner wall of the tail sleeve, which is convenient for installation and disassembly. The assembly process of this LC connector is relatively simple, does not require crimping, and has fewer components and low cost. Description of the Drawings
