Fig.24 Schematic diagram of the appearance of the first metal shell 1 and the second metal shell 2 when they are assembled, with the docking protrusion 17 of the first metal shell 1 aligned with the docking recess 27 of the second metal shell 2. Fig.25 It is a schematic diagram of the appearance of the first metal shell 1 and the second metal shell 2 after being assembled, in which the docking protrusion 17 of the first metal shell 1 is docked with the docking recess 27 of the second metal shell 2; in some embodiments, when the second metal shell 2 is to be installed on top of the first metal shell 1, the stop blocks 29 of the second metal shell 2 are passed over the shoulders 412 of the pressing member 4, so that the limiting grooves 28 are aligned with the shoulders 412 of the pressing member 4, and then the second metal shell 2 is correspondingly covered on top of the first metal shell 1, and then the second metal shell 2 is moved on the first metal shell 1, so that the docking protrusions 17 are respectively docked with the docking recesses 27, and the shoulders 412 of the pressing member 4 are respectively locked in the limiting grooves 28, thereby completing the assembly operation of the first metal shell 1 and the second metal shell 2.

[0111] See also Fig. 20 , Fig. 20 2 is a schematic diagram of the appearance of the second metal shell 2. The second metal shell 2 has an assembly slot 26 and is in a rectangular structure with the second docking portion 21. The lower surface of the second metal shell 2 does not include a stop block 29. In some embodiments, the lower surface of the second metal shell 2 does not include a stop block 29 (i.e., the stop block 29 is deleted). Fig.19 When the second metal shell 2 is to be installed on the top of the first metal shell 1, the second metal shell 2 is correspondingly covered on the top of the first metal shell 1, and then the second metal shell 2 is slidably moved on the first metal shell 1, so that each docking protrusion 17 is docked with each docking recess 27, and each shoulder 412 of the pressing member 4 is respectively locked in each limiting groove 28, so as to simply complete the assembly operation of the first metal shell 1 and the second metal shell 2.

[0112] See also Fig.26 , Fig.26 The figure is a schematic diagram of the side appearance of the optical fiber connector 100, in which the upper surface of the second metal shell 2 is higher than the upper surface of each coupling body 31; in some embodiments, the upper surface of each coupling body 31 has a first horizontal plane 31a, and the upper surface of the second metal shell 2 has a second horizontal plane 2a. The metal stopper 35 has a fulcrum 35a connected to the surface of the coupling body 31, and the second horizontal plane 2a and the fulcrum 35a are located on the same horizontal axis. The second horizontal plane 2a is higher than the first horizontal plane 31a and is adjacent to the side end of the metal stopper 35; when the pressing portion 42 is pressed and the metal stopper 35 is linked to swing, the side end of the metal stopper 35 will move toward the second horizontal plane 2a and the side end of the metal stopper 35 is suitable for abutting against the second horizontal plane 2a. Because the side end of the metal stopper 35 abuts against the second horizontal plane 2a which is higher than the first horizontal plane 31a, the side end of the metal stopper 35 is prevented from swinging too much and deforming, and the problem that the side end of the metal stopper 35 cannot rebound and return to its original position is avoided.

[0113] In summary, according to some embodiments, a first metal shell and a second metal shell made of metal material provide a solid structure to prevent damage, thereby extending the service life of the optical fiber connector; secondly, according to some embodiments, a plug is fixed to the through hole of the coupling body and abuts against the elastic component to firmly limit the elastic component in the through hole; furthermore, according to some embodiments, there are multiple combination methods between the coupling body, the first metal shell and the second metal shell, and between the first metal shell and the second metal shell for easy matching and use.
