An anti - detachment protrusion 54 protruding from the upper slot of the wire groove 53 is integrally fixed on the upper side wall of the welding partition 52, so that the size of the upper slot of the wire groove 53 is reduced. After the protective sleeve at the wire welding position is clamped in the wire groove 53, the anti - detachment protrusion 54 can effectively prevent the wire from coming out of the wire groove 53.

[0039] An articulated ear plate 55 is convexly fixedly connected to the outer side wall of the welding partition 52 close to the side wall of the box body 1. There are two articulated ear plates 55 and they are spaced along the length direction of the welding partition 52. An articulated shaft 56 is fixedly connected between the two articulated ear plates 55, and there is a gap between the articulated shaft 56 and the welding partition 52.

The articulated shaft 56 can be inserted into / removed from the rotating groove 131 through the installation groove 132.

[0040] Referring to Figure 3 、 Figure 6, a support plate 14 for abutting against the lower end face of the welding bottom plate 51 is integrally and convexly fixed on the inner wall of the bottom of the box body 1.

The binding band can be a cable tie or a Velcro tie.

[0042] The implementation principle of the optical fiber fusion splicing module box in the embodiment of the present application is as follows: the fusion splicing clamping seat 5 of the optical fiber fusion splicing module box can be foldably connected to the inner wall of the box body 1. During the wiring process, the fusion splicing clamping seat 5 can be folded to the vertical state to reduce the occupied space, which is convenient for the staff to insert the wiring terminal of the optical fiber cable at the input end into the input wiring port 32 of the adapter 3. And after the too-long optical fiber cable can be wound around the outer peripheral wall of the support plate 14, the fusion splicing clamping seat 5 is folded to the horizontal state, so that the clamping head 141 is buckled in the clamping hole 57. Then, the protective sleeve fixedly sleeved on the cable fusion splicing position is clamped in the wire groove 53. Subsequently, the wire harness is fixed by the binding band, and finally the box cover 2 is closed.

[0043] The hinge shaft 56 can be easily inserted into or removed from the rotating groove 131 through the installation groove 132, so as to facilitate the installation and disassembly of the fusion splicing clamping seat 5. According to different use requirements, the corresponding fusion splicing clamping seat 5 can be configured, improving the flexibility and construction efficiency of the optical fiber fusion splicing module box in the optical fiber wire harness construction.
