Description

Technical Field

[0001] This utility model relates to the field of telecommunications fiber optic box technology, and more specifically, to a wall-mounted telecommunications fiber optic box. Background Technology

[0002] An optical fiber distribution box is a device for terminating optical cables in wiring closets and equipment rooms. It is suitable for wiring connections between optical cables and optical communication equipment. Through the adapters inside the distribution box, optical signals are led out using optical patch cords to realize optical wiring functions. It is suitable for protective connections of optical cables and pigtails, and is also suitable for use at optical fiber terminal points in optical fiber access networks.

[0003] A search revealed that prior art CN220526072U discloses a wall-mounted fiber optic box, including a mounting plate and a box body. The box body is fixedly mounted on one side of the mounting plate via a mounting mechanism and a limiting mechanism. The mounting mechanism includes a snap-fit ​​groove. The snap-fit ​​plate and snap-fit ​​groove allow for snap-fit ​​installation between the box body and the mounting plate. Simultaneously, the movable rod, under the torque of the torsion spring shaft, stops at the top of the box body, thus limiting its position and preventing it from wobbling under vibration, resulting in high stability. Furthermore, the rubber protrusions and grooves limit the movable rod, preventing it from shaking. The limiting groove also limits the bolts, preventing them from falling off, improving the robustness and practicality of the wall-mounted fiber optic box. However, the aforementioned patent has the following shortcomings: the strength of mounting the box body on the back using only a snap-fit ​​groove and a snap-fit ​​plate is insufficient; additionally, another worker is required to operate the movable rod during installation, resulting in inconvenience. Therefore, we propose a wall-mounted telecommunications fiber optic box. Utility Model Content
