Description

Technical Field

[0001] This utility model relates to the field of optical cable junction boxes, and in particular to a novel optical cable junction box. Background Technology

[0002] Optical fiber splice closures are critical equipment in optical fiber communication networks, used for splicing, branching, and providing physical protection for fiber optic connectors. As optical fiber networks evolve towards higher density, longer distances, and higher reliability, the design of the fiber coiling structure within the splice closure directly impacts the transmission performance and maintenance efficiency of the optical cable line. Traditional splice closures often employ a single-layer planar fiber coiling structure, which can easily lead to fiber overlap and crossing due to insufficient space during coiling. Micro-bending loss occurs between adjacent fibers due to compression, especially in dense fiber deployments where the bending radius may be lower than industry standards (typically ≥30mm), causing signal attenuation or even breakage.

[0022] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to Figures 1 to 2 This utility model provides a novel optical cable junction box, including a box body 100 and an optical fiber tray installed inside the box body 100;

[0024] The fiber optic disk includes a unit disk body 200 and an end cap 205;

[0025] The unit disk 200 has a top-opening structure, and both ends of the unit disk 200 are provided with inlets and outlets for optical cables to enter and exit. The outer wall of the unit disk 200 is provided with multiple positioning blocks 201. The top of the positioning block 201 is recessed with a positioning groove 203, and the bottom of the positioning block 201 is provided with a positioning protrusion 204 corresponding to the positioning groove 203. Adjacent unit disks 200 are stacked and combined by positioning grooves 203 and positioning protrusions 204. The bottom of the unit disk 200 is provided with a limiting protrusion 206. The limiting protrusion 206 of the upper unit disk 200 enters the disk body of the lower unit disk 200, so that a racetrack-shaped optical fiber coiling space is formed inside the unit disk 200.

[0026] End cap 205 is installed on the topmost unit disk 200;

[0027] In use, according to the requirements of optical cable cabling, the corresponding number of unit trays 200 are stacked and combined to realize the combined installation of multiple unit trays 200. Each layer of unit trays 200 can independently coil optical fibers, which can effectively avoid the optical fibers from crossing and overlapping due to insufficient space during the coiling process. After adjacent unit trays are combined, a racetrack-shaped optical fiber coiling space is formed within the unit tray 200. The racetrack-shaped optical fiber coiling space can prevent the optical cable from scattering loss due to excessive bending, thereby reducing signal attenuation and ensuring stable transmission of optical signals. In addition, with the stackable unit trays 200, when the unit tray 200 is opened, the optical fiber coiling is in a semi-open state, which facilitates internal maintenance.

[0028] In this embodiment, the bottom of the unit disk 200 located at the bottom does not have a limiting protrusion 206, and is fixedly installed on the bottom of the inner wall of the box 100.

[0029] In this embodiment, the top opening of the unit disk 200 is provided with multiple limiting baffles 202 to prevent optical fibers from detaching.

[0030] In this embodiment, the end cap 205 is threadedly connected to the unit disk 200 by the screw 207. The positioning block 201 of the unit disk 200 has a screw hole corresponding to the screw 207. The screw 207 is threadedly connected to the screw hole on the positioning block 201 of each unit disk 200. The bottom of the end cap 205 is also provided with a limit protrusion 206. The unit disks 200 are fixedly connected by tightening the screw 207.

[0031] In this embodiment, the housing 100 includes an upper housing and a lower housing, which are connected by a hinge. Both ends of the upper housing and the lower housing are provided with semi-circular interfaces. When the upper housing and the lower housing are connected, the two semi-circular interfaces form a connection interface that facilitates the entry and exit of optical cables or optical fibers.

[0032] The working principle of this utility model is as follows:

[0033] According to the requirements of optical cable cabling, a corresponding number of unit trays 200 are stacked and combined to realize the combined installation of multiple unit trays 200. Each layer of unit trays 200 can independently coil optical fibers, which can effectively avoid the optical fibers from crossing and overlapping due to insufficient space during the coiling process. After the adjacent unit trays are combined, a racetrack-shaped optical fiber coiling space is formed within the unit tray 200. The racetrack-shaped optical fiber coiling space reduces the twisting and compression of the optical cable during the coiling process, reduces the stress level of the optical fiber, and can prevent the optical cable from scattering loss due to excessive bending, thereby reducing signal attenuation and ensuring stable transmission of optical signals.

[0034] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
