Description

Technical Field

[0001] This utility model relates to the field of patch panel technology, and in particular to an optical fiber patch panel. Background Technology

[0002] Fiber optic distribution boxes are suitable for wiring connections between optical cables and optical communication equipment. They are essential in network construction. Through the adapters inside the distribution box, optical signals are led out using optical patch cords to realize optical wiring functions. They are suitable for protective connections of optical cables and pigtails, and are also suitable for use at fiber optic terminal points in fiber optic access networks.

[0003] For example, patent application number CN202420552541.4 discloses a waterproof fiber optic distribution box, including a box body and a cover. The cover is hinged to the box body, and a latch that cooperates with the box body is provided on the inner outer edge of the cover. A limit switch is provided on the upper front of the box body. A first sealing strip is provided on the edge of the box body, and a second sealing strip is provided on the edge of the cover. From left to right, a circuit breaker, a surge protection module, a socket, a switching power supply, a power splitter, and a 485 serial port server are arranged in sequence inside the upper part of the box body. This distribution box has advantages such as good sealing performance. To organize excess fiber optic cables inside the distribution box, some distribution boxes have a winding reel inside the box body. The winding reel has multiple positioning posts, and the fiber optic cables are evenly wound around the outside of the positioning posts, thereby avoiding fiber optic cable tangling and confusion. However, when there are too many excess fiber optic cables in the distribution box, during maintenance, accidental contact can easily cause some fiber optic cables to break off from the positioning posts, affecting subsequent maintenance.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes an optical fiber distribution box, including a box body 1 and a mounting plate 4 located inside the box body 1. An adapter 5 and an optical splitter 7 are installed on the upper end of the mounting plate 4. The adapter 5 is provided with multiple connectors 6. The connectors 6 are connected to optical fiber lines 8. The end of the optical fiber line 8 away from the connector 6 passes through the winding device at the upper end of the box body 1 and is connected to the user port 10 located on the side of the box body 1.

[0021] The optical fiber of the external trunk optical cable is first connected to the optical splitter 7 for signal distribution, and then connected to the optical fiber line 8 through the connector 6 on the adapter 5 to realize the initial transmission of optical signal. After the optical fiber line 8 is wound up by the winding device, the optical signal is transmitted to the user port 10.

[0022] The winding device includes a winding reel 9, which is placed between the user port 10 and the adapter 5 and is fixedly connected to the housing 1. The upper end of the winding reel 9 is provided with multiple first positioning posts 11. A second positioning post 12 is provided on the side of the first positioning post 11 near the center of the winding reel 9. A stop sleeve 13 is fitted on the second positioning post 12, and the stop sleeve 13 is threadedly connected to the second positioning post 12.

[0023] The first positioning post 11 and the second positioning post 12 cooperate to form a winding channel for the optical fiber 8, which organizes the excess optical fiber 8. The first positioning post 11 and the second positioning post 12 can control the bending radius of the optical fiber 8, avoiding optical signal attenuation caused by excessive bending of the optical fiber 8. The stop sleeve 13 installed on the second positioning post 12 can be rotated and inserted into the line gap to fix the wound optical fiber 8, ensuring that the optical fiber 8 will not slip off the positioning post and unravel, resulting in better storage effect.

[0024] It is worth explaining in detail that the second positioning post 12 has an adjustment thread 15 on its outer side, the inner side wall of the stop sleeve 13 is threaded to the adjustment thread 15, and the outer edge of the stop sleeve 13 has a stop protrusion 14 for locking the gap between the first positioning post 11 and the second positioning post 12. The stop protrusion 14 is fixedly connected to the stop sleeve 13.

[0025] Workers can rotate the stop sleeve 13 to move it up and down along the adjusting thread 15 of the second positioning post 12. When the fiber optic cable 8 is wrapped around the gap between the first positioning post 11 and the second positioning post 12, moving the stop sleeve 13 can drive the stop protrusion 14 to engage in the gap, thereby firmly fixing the fiber optic cable 8 in the gap and preventing the fiber optic cable 8 from shifting when the housing 1 shakes or is pulled by external force. No additional fasteners such as cable ties are needed, making the fixing of the fiber optic cable 8 simpler.

[0026] In a preferred embodiment, the retaining protrusion 14 is made of rubber, and its length is equal to the distance between the first positioning post 11 and the second positioning post 12. The rubber retaining protrusion 14 has good elasticity, and when it is inserted into the gap between the first positioning post 11 and the second positioning post 12, it can not only fit tightly against the inner wall of the gap to fix the line, but also avoid scratching or squeezing damage to the optical fiber 8 caused by hard materials.

[0027] It is worth explaining in detail that the lower end of the first positioning post 11 is detachably connected to the upper end of the winding disc 9, and the lower end of the second positioning post 12 is fixedly connected to the upper end of the winding disc 9.

[0028] In a preferred embodiment, the lower end of the first positioning post 11 is provided with a threaded post 16, which is fixedly connected to the first positioning post 11. The threaded post 16 is threadedly connected to a threaded hole 17 on the upper end of the winding reel 9. When it is necessary to install or remove the first positioning post 11, the threaded post 16 at the lower end can be rotated to loosen or tighten the threaded hole 17 on the winding reel 9, thereby completing the installation or removal of the first positioning post 11.

[0029] To keep the wiring box sealed, a cover 2 is provided at the top of the box body 1. The side of the cover 2 is rotatably connected to the box body 1 via a hinge structure. A sealing strip 3 is provided on the inside of the cover 2, which fits snugly against the inner wall of the box body 1. The cover 2 can be opened and closed flexibly via the hinge structure, facilitating the installation and maintenance of the internal components of the box body 1. When the cover 2 is closed, the sealing strip 3 on the inside of the cover 2 will fit tightly against the inner wall of the box body 1, filling the gap between the cover 2 and the box body 1, thereby preventing dust, moisture, insects and other impurities from entering the interior of the box body 1.

[0030] How this application works:

[0031] After the external backbone optical cable is connected to the housing 1, it is connected to the optical fiber 8 via the connector 6 on the adapter 5. The optical fiber 8 can be wound and stored on the winding reel 9. By adjusting the stop sleeve 13 on the outside of the second positioning post 12, the position of the stop protrusion 14 is adjusted by adjusting the adjusting thread 15 to fix the optical fiber 8 after winding and prevent it from loosening. The optical splitter 7 distributes the backbone optical signal to each optical fiber 8, and finally connects to the user optical modem through the user port 10.
