The present invention relates generally to the technical field of optical modules, and more particularly to an assembly component for mounting a cylindrical optical fiber terminal box.
An optical fiber splice closure is mainly applicable to straight-through and branch connection of optical cables of various structures that are laid in a manner such as aerial laying, pipe laying, and directly-buried laying. The optical fiber splice closure is generally applied to different scenarios according to customer requirements, for example, being directly mounted on a wall, being mounted on a utility pole by means of a hoop, or being hung on a household cable. For a cuboid optical fiber splice closure, an existing mounting bracket can be completely adapted to the above scenarios. However, for a cylindrical optical fiber terminal box, an outer circumferential surface of the terminal box is not flat, which cannot be adapted to the mounting bracket effectively, and therefore, smooth mounting of the cylindrical optical fiber terminal box in various scenarios cannot be ensured. Even if the cylindrical optical fiber terminal box is assembled by means of the mounting bracket in the prior art, the cylindrical optical fiber terminal box cannot be adapted and mounted to the utility pole, wall or rope, a risk of falling off may be caused. Meanwhile, the mounting bracket in the prior art is not conducive to smooth switching of various scenarios. Therefore, it is urgent to develop an assembly component for mounting a cylindrical optical fiber terminal box, so that the cylindrical optical fiber terminal box can be adapted to three mounting scenarios, i.e., mounting on the wall, mounting on the utility pole, and hanging on the household cable.
