Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical fibers, in particular to a high-density, easily replaceable optical cable sealing component and an optical fiber joint box. Background Art
[0002] The main function of the fiber optic splice box is to split the optical cable into single optical fibers, which is installed on the wall, cable, pole or sewer. Its function is to provide the fusion splicing of optical fibers, the fusion splicing of optical fibers and pigtails, and the handover of optical connectors. The fiber optic splice box is mainly suitable for the straight-through and branching connections of various structural optical cables in the aerial, pipeline, direct burial and other laying methods. After the optical cable enters the fiber optic splice box, its outer sheath and reinforcing core must be mechanically fixed, the ground wire protection component must be installed, the end protection treatment must be performed, and the optical fibers must be grouped and protected.
[0003] Among them, the prior art generally adopts the following technical solutions to fix the optical fiber splice box: Figure 14-18 As shown, the optical fiber splice box sealing assembly includes two conventional circular holes. At the same time, the optical fiber splice box sealing assembly is specially used for digging and splicing optical cables, so its assembly must be divided into two parts, an upper shell and a lower shell, which are separated from each other (such as Fig.15 ), the two components are installed by splicing, so the optical fiber splice box sealing assembly of the prior art has the following defects:
[0004] Even if the same type of breakout card is used for the two conventional round hole fiber optic splice box sealing components, at most six fiber outlet holes can be separated. With the development of the optical communication industry, customers have higher and higher requirements for use, and the demand for fiber outlet holes in the fiber optic splice box is also increasing. The original six-hole design is far from meeting the growing demand; at the same time, the installation method of splicing the two components up and down cannot guarantee waterproof performance.
[0005] In addition, the fiber outlet holes connected with the breakout cards only have two states: either all sealed or all empty. That is, each fiber outlet hole with a breakout card cannot quickly adjust the number of branched fiber outlet holes according to actual working conditions. For example, one fiber outlet hole is divided into three branch fiber installation holes by a breakout card, but in actual conditions only two optical fibers need to be installed in the three branch fiber installation holes. Then the extra branch fiber installation hole is in an empty state, which may cause problems such as water seepage in the later stage.
[0006] Therefore, it is urgent to design a high-density, easily replaceable optical cable sealing assembly to solve the above technical problems. Utility Model Content
