Description

Technical Field

[0001] This utility model relates to the field of fiber optic distribution frame technology, specifically a moisture-proof fiber optic distribution frame. Background Technology

[0002] As the core connection hub in fiber optic communication systems, fiber optic distribution frames are widely used in data centers, communication equipment rooms, base stations, and edge computing sites. They primarily undertake the functions of splicing, distribution, scheduling, and protection of fiber optic links, and their operational stability directly determines the quality and reliability of fiber optic signal transmission. With communication networks extending into complex environments such as outdoor and semi-outdoor environments (e.g., underground equipment rooms, base stations in rainy areas), environmental humidity has become a key factor affecting the lifespan and operational performance of fiber optic distribution frames. Currently available fiber optic patch panels have significant shortcomings in their moisture-proof design, mainly in the following three aspects: First, unused network cable interfaces lack reliable sealing structures. Most patch panels rely solely on simple plastic dust covers to shield unused interfaces, leaving gaps between the covers and the interfaces. Moisture can easily seep into the interfaces, causing oxidation and corrosion of the metal contacts, leading to poor signal contact, increased insertion loss, and in severe cases, short circuits, affecting the normal conduction of the fiber optic link. Second, the back fiber optic connection area lacks adequate protection and sealing. Core components such as fiber optic splices and patch cords on the back of the patch panel are often exposed to open or semi-open environments, protected only by simple housings, which cannot effectively isolate external moisture. Furthermore, the cable management structure of some patch panels is disorganized, with loose fiber arrangement creating gaps between the housing and the cables. Moisture can easily seep in along these gaps and adhere to the splice surface, causing increased splice attenuation and a significant decrease in signal transmission stability. Third, moisture-proof maintenance is inconvenient. A few patch panels with basic moisture-proof functions have built-in desiccants, but the desiccants are mostly fixed in a sealed design. When replacing them, multiple parts such as the sealing cover and cable management rack of the patch panel need to be disassembled, which is cumbersome and can easily damage the original sealing structure. This results in insufficient moisture-proof effect and the internal components still face the problem of aging due to moisture after long-term use. Therefore, addressing the pain point of insufficient moisture resistance in existing fiber optic distribution frames, designing a moisture-proof fiber optic distribution frame that is reliably sealed, has a long-lasting moisture-proof effect, and is easy to maintain has become an important research and development direction in the field of fiber optic communication equipment.

[0015] like Figures 1 to 4As shown, a moisture-proof fiber optic patch panel includes a patch panel body 1. Several network cable interfaces 2 are evenly distributed on the front of the patch panel body 1. An elastic cord 4 is fixedly connected to the bottom of the front of the patch panel body 1. A rubber plug 3 is installed inside each network cable interface 2. The end of the elastic cord 4 away from the patch panel body 1 is fixedly connected to the rubber plug 3. A sealing cover 5 is fixedly connected to the back of the patch panel body 1. The top of the sealing cover 5 is secured by a screw... A sealing cover 6 is fixedly connected to the bolt and nut. Cable management frames 7 are fixedly connected to the front and rear sides of the bottom of the sealing cover 6 and the front and rear sides of the bottom of the inner wall of the sealing cover 5. Multiple evenly distributed semi-circular cable-holding grooves 15 are provided on the surface of the cable management frames 7. Semi-circular silicone blocks 8 are fixedly connected inside the semi-circular cable-holding grooves 15 on the back side, with the upper and lower semi-circular silicone blocks 8 fitting together. The upper and lower cable management frames 7 also fit together. Mounting blocks 16 are fixedly connected to both sides of the cable management frame body 1. The surface of the mounting blocks 16 has... The mounting port 17 and the above-mentioned patch panel body 1 are common existing technologies and are common knowledge to those skilled in the art. This application will not describe them in detail. After the sealing cover 6 is installed, the upper and lower corresponding cable management racks 7 fit together. The semi-circular cable slot 15 is used to manage the optical fiber. The semi-circular silicone block 8 can prevent external moisture from entering the area between the sealing cover 5 and the sealing cover 6 to a certain extent, thereby protecting the back components of the patch panel body 1. The standard parts used in this utility model can all be purchased from the market. The irregular parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

A sealing ring is provided between the sealing cover 5 and the sealing cover 6, which can improve the sealing performance after the sealing cover 5 and the sealing cover 6 are installed. The sealing ring is not shown.

[0016] refer to Figure 1 The rubber plug 3 has a fixed connection to a lever on its front side, and the lever is made of rubber.

[0017] As a technical optimization of this utility model, by setting a pry block on the front of the rubber plug 3, and the pry block is made of rubber, no additional tools are needed during use. The rubber plug 3 can be easily removed or installed from the network cable interface 2 simply by using the pry block, which greatly improves the convenience of operation. At the same time, the rubber pry block is soft and will not cause scratch damage to the rubber plug 3 or the network cable interface 2 during operation, thus balancing convenient operation and structural protection.

[0018] refer to Figure 2The top of the sealing cover 6 has an opening 13, and the top of the opening 13 is connected to a drying hood 9. A drawer 10 is slidably connected inside the drying hood 9, and a desiccant is placed inside the drawer 10.

[0019] As a technical optimization of this utility model, a drawer 10 containing desiccant is slidably connected inside the drying cover 9. The desiccant can continuously absorb moisture in the space enclosed by the sealing cover 5 and the sealing cap 6, keeping the internal environment dry and preventing damage to the main body 1 of the patch panel due to moisture. The drawer 10 can slide back and forth. When the moisture absorption capacity of the desiccant decreases, the drawer 10 can be easily pulled out of the drying cover 9 to replace the desiccant without disassembling the sealing cap 6. The operation is simple and effectively ensures the continuity of the device's moisture-proof effect, extending the service life of the patch panel.

[0020] refer to Figure 2 A support rod 14 is fixedly connected inside the opening 13. There are several support rods 14, which are evenly distributed inside the opening 13. The top of the support rod 14 fits against the bottom of the drawer 10.

[0021] As a technical optimization of this utility model, by fixing a support rod 14 inside the opening 13 and having the support rod 14 fit against the bottom of the drawer 10, a stable support can be provided for the drawer 10, ensuring that the drawer 10 can always slide smoothly inside the drying cover 9. At the same time, the support rod 14 is evenly distributed inside the opening 13, so it will not affect the air permeability of the opening 13. Moisture can still pass through the opening 13 smoothly into the drying cover 9 and come into contact with the desiccant. This ensures the normal use of the drawer 10 without affecting the moisture-proof effect of the device, and improves the overall structural stability.

[0022] refer to Figure 2 The drawer 10 has openings 11 on both sides and the back, and a ventilation mesh 12 is fixedly connected inside the openings 11.

[0023] As a technical optimization of this utility model, by opening 11 on both sides and the back of the drawer 10 and fixing a breathable mesh 12 thereon, the breathable mesh 12 allows the moisture in the space enclosed by the sealing cover 5 and the sealing cap 6 to smoothly enter the interior of the drawer 10 through the opening 11 and fully contact the desiccant, ensuring that the desiccant can efficiently absorb moisture and guarantee the drying effect. At the same time, the breathable mesh 12 can effectively prevent the desiccant particles inside the drawer 10 from leaking out, preventing the desiccant particles from entering the interior of the sealing cover 5 and contaminating the main body 1 of the wiring rack, preventing the particles from affecting the normal operation of the components, and ensuring the cleanliness of the device and the safety of the components while improving the drying efficiency.

[0024] refer to Figure 1 The front of drawer 10 extends to the front of drying cover 9 and is fixedly connected with a handle. Drawer 10 and drying cover 9 are fixedly connected by screws.

[0025] As a technical optimization of this utility model, the front of the drawer 10 extends to the front of the drying cover 9 and is equipped with a handle. When replacing the desiccant, the drawer 10 can be easily pulled out of the drying cover 9 using the handle, without the need for strenuous prying, greatly improving the ease of operation. The drawer 10 and the drying cover 9 are fixed together with screws, which can effectively prevent the drawer 10 from sliding out of the drying cover 9 due to vibration or accidental contact during the use of the device, ensuring that the desiccant in the drawer 10 is always in the correct position and stably plays its moisture-absorbing role. This avoids interruption of the moisture-proof effect due to the drawer 10 accidentally sliding out, thus balancing ease of operation and structural stability.

[0026] The working principle and usage process of this utility model are as follows: When in use, open the sealing cover 6 at the top of the sealing cover 5 with a tool, install the optical fiber to be connected, and place it in the semi-circular cable tray 7 at the bottom of the inner wall of the sealing cover 5 in sequence, so that the optical fiber fits into the semi-circular cable tray 15. At the same time, ensure that the semi-circular silicone block 8 located in the semi-circular cable tray 15 on the back is in close contact with the optical fiber. Then, put the sealing cover 6 back on the top of the sealing cover 5, and use bolts and nuts to firmly connect the sealing cover 6 to the sealing cover 5. At this time, the upper and lower corresponding cable trays 7 will fit together, further fixing the optical fiber and enhancing the sealing effect, preventing external moisture from entering from the back.

[0027] When the network cable interface 2 is needed, gently pull the lever on the front of the rubber plug 3 to remove the rubber plug 3 from the network cable interface 2. At this time, the elastic cord 4 connected to the rubber plug 3 will keep the rubber plug 3 connected to the patch panel body 1 to prevent the rubber plug 3 from being lost. Insert the network cable into the network cable interface 2 to complete the connection. If the network cable interface 2 is not in use for the time being, use the lever to push the rubber plug 3 back into the network cable interface 2 to seal the network cable interface 2 and prevent external moisture from entering.

[0028] Regularly inspect drawer 10 inside drying cover 9. If desiccant needs to be replaced, first unscrew the screws between drawer 10 and drying cover 9, hold the handle on the front of drawer 10 and pull drawer 10 out of drying cover 9. At this time, the support rod 14 inside the opening 13 will disengage from the bottom of drawer 10. Remove the expired desiccant from drawer 10 and put in new desiccant. Note that there are ventilation meshes 12 at the openings 11 on both sides and the back of drawer 10 to ensure that subsequent moisture can smoothly enter drawer 10 and come into contact with desiccant. After that, push drawer 10 back into drying cover 9 and tighten the screws to secure it, ensuring that drawer 10 is stable and will not slide out on its own. The operator can install the patch panel body 1 in the cabinet through the mounting block 16 and mounting port 17.
