Description

Technical Field

[0001] This utility model relates to the field of optical communication, and in particular to an optical communication housing with optical fiber fixing function. Background Technology

[0002] In the current era of rapid development in optical communication technology, optical communication equipment, as the core carrier of signal transmission, directly affects the overall communication quality due to the stability and functionality of its internal structure. Among them, the optical communication housing, as the protection and installation carrier for optical fibers and optical components, must simultaneously meet two core requirements: efficient fiber fixation and convenient housing assembly, in order to adapt to the deployment and maintenance of communication equipment in various scenarios.

[0003] This application improves upon the existing technology, in which the optical communication housings currently on the market have obvious technical limitations in the optical fiber fixing process: most housings use an integrated or single-specification clamping structure to fix the optical fiber, which can only be adapted to optical fibers of a specific diameter. When dealing with optical fibers of different outer diameters (such as the common 0.25mm tight-buffered fiber and 0.9mm loose-buffered fiber), either the fiber sheath is damaged due to excessive clamping, affecting signal transmission, or the fiber is displaced within the housing due to excessive clamping, causing signal attenuation or connection interruption. This makes it difficult to meet the practical application requirements of sharing the same housing with multiple fiber specifications. On the other hand, the fiber splitting design of existing housings is relatively simple, relying mostly on manual combing of the fiber before fixing, lacking a dedicated splitting structure. When multiple fibers need to be fixed at the same time, fiber entanglement and crossing are very likely to occur, which not only increases the difficulty of installation, but also prolongs maintenance time due to the difficulty in fiber identification. At the same time, in existing housings, the fixing plates, pressure plates and other components used for fixing fibers are usually directly connected to the inner wall of the housing with multiple sets of bolts. During installation, the position of the components needs to be repeatedly calibrated, and the bolt tightening operation needs to be completed step by step with the help of multiple tools. The assembly process is cumbersome and time-consuming. Utility Model Content

[0013] As a further embodiment of this utility model: symmetrically distributed support plates are provided between the two positioning posts, and the support plates are fixedly connected to the optical communication housing.

The stud is rotated, and the stud drives the connecting rod to move, which in turn drives the pressure plate to move down through the movable column to fix the optical fiber. For optical fibers with larger outer diameters, the optical fiber will push the pressure block, causing the pressure block to move up and enter the groove. The spring contracts, and through the elastic action of the spring, the device fixes optical fibers of different diameters. Attached Figure Description
