Description

Technical Field

[0001] This utility model belongs to the field of communication equipment technology, and specifically relates to an optical cable distribution box that is easy to maintain. Background Technology

[0002] Fiber optic distribution boxes are interface devices used to connect backbone fiber optic cables and distribution layer fiber optic cables. They integrate fiber optic cable introduction (fixing, stripping, and protection), fiber optic splicing, fiber optic branching, and distribution, and independently complete fiber optic distribution management functions.

[0003] In traditional optical fiber distribution boxes, fiber optic splitters are installed in an overlapping manner, with the front of adjacent fiber optic splitters blocking each other. This makes it inconvenient for workers to perform splicing, distribution, inspection and maintenance. This structural layout is not conducive to the later inspection, maintenance and fiber sorting and management by construction personnel. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an easy-to-maintain optical fiber distribution box with a reasonable structural design and layout, which facilitates splicing, distribution and maintenance operations by staff.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: an easy-to-maintain optical fiber distribution box, including a box body and a fiber splicing tray set in the box body. The box body is provided with two layers of flip-plates that can be flipped in the horizontal direction. The two layers of flip-plates are staggered. At least one independently distributed optical fiber splitter is installed on each layer of flip-plates. The optical fiber splitters on each layer of flip-plates are laid along the surface of the plate body.

[0006] As a preferred technical solution, two fiber optic splitters are installed on each flip panel, and the two adjacent fiber optic splitters do not interfere with each other.

[0007] As a preferred technical solution, the box body is provided with two left and right flap fixing frames, and the two flaps are respectively hinged to the flap fixing frames.

[0008] As a preferred technical solution, the two flip plates rotate in opposite directions.

[0009] As a preferred technical solution, an optical cable fixing seat is provided inside the box below the two flip-up panels.

[0010] As a preferred technical solution, the fiber melting tray is hidden behind the rear flip plate.

[0011] Compared with the prior art, the present invention has the following advantages: each fiber optic splitter adopts a flip-type installation and a front-panel layout design to achieve independent distribution of each fiber optic splitter. The labels of each splitter are clearly visible, there is no front-panel obstruction, the line layout is reasonably planned, and it is convenient for fiber optics to be sorted and managed, making it more convenient for staff to perform fiber optic splicing, distribution, inspection and other maintenance work.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0019] like Figures 1 to 4 As shown, the easy-to-maintain optical fiber distribution box includes a box body 1 and a fiber splicing tray 2 (a 12-core fiber splicing tray) set inside the box body 1. The box body 1 is provided with two layers of flip-plates 3 that can be flipped horizontally. The two layers of flip-plates 3 are stacked alternately, increasing the depth of the box body by 30mm. Each layer of flip-plates 3 is equipped with an independently distributed optical fiber splitter 4, and the optical fiber splitter 4 on each layer of flip-plates 3 is laid flat along the surface of the plate body.

[0020] In this embodiment, two independently distributed fiber optic splitters 4 are installed on each flip plate 3. The two adjacent fiber optic splitters 4 do not interfere with each other, and the labels of each splitter are clearly visible. There is no frontal obstruction, which facilitates the sorting and management of optical fibers.

[0021] In this embodiment, the housing 1 is equipped with two left and right flap fixing frames 5, which are designed to be of different heights. The front flap 3 is hinged to the higher flap fixing frame 5, and the rear flap 3 is hinged to the lower flap fixing frame 5, thus achieving a staggered design. (Reference) Figure 3 and Figure 4 The two flip plates 3 rotate in opposite directions. When rotated outward by 90°, the two flip plates 3 open outward respectively. After the flip plates 3 open by 90°, it is necessary to ensure that the fiber optic splitter 4 does not interfere with the edge of the enclosure 1; Reference Figure 1 and Figure 2 When rotated 90° inward, the two flip plates 3 return to their staggered state.

[0022] refer to Figure 1 To facilitate fiber optic cable fixing and wiring layout, a fiber optic cable fixing seat 6 is provided inside the housing 1, below the two layers of flip panels 3. (Reference) Figure 3 In order to further reduce the width of the box, the fiber fusion tray 2 is hidden behind the rear flap 3.

[0023] In this utility model, each fiber optic splitter is installed using a flip-type design and a front-mounted flat layout design to achieve independent distribution of each fiber optic splitter, rationally plan the line layout, facilitate the sorting and management of optical fibers, and make it more convenient for staff to perform maintenance work such as fiber splicing, distribution, and repair.

[0024] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
