The L-shaped block 11 and the L-shaped groove 12 ensure that when the two shells 1 are ultrasonically welded, the L-shaped block 11 will be welded together with the inner wall of the L-shaped groove 12, thereby increasing the contact area and making the welding of the two shells 1 more secure. An insert 15 is provided on one side of the L-shaped block 11. The insert 15 and the protrusion 4 can block the metal spring 2 and prevent the metal spring 2 from separating from the shell 1, thereby ensuring the firmness and reliability of the fiber optic adapter and the fiber optic box after assembly. A through groove 6 that matches the insert 15 is provided on the shell 1, and the through groove 6 facilitates the insert 15 to pass through the shell 1.

[0016] Among them, a positioning hole 10 and a positioning column 9 are respectively provided on the adjacent sides of the two shells 1. The positioning column 9 and the positioning hole 10 are used together to play a positioning role between the two shells 1 to avoid displacement between the two shells 1.
