Technical Field

[0001] This utility model relates to the field of wavelength division multiplexer technology, specifically a pluggable wavelength division multiplexer with port wiring protection. Background Technology

[0002] Wavelength division multiplexers (WDMs) are core devices in optical fiber communication systems. They enable high-capacity signal transmission over a single optical fiber by multiplexing and demultiplexing optical signals of different wavelengths. Plug-in WDMs are widely used in various communication networks due to their flexible installation and convenient maintenance.

[0003] However, existing products have obvious defects: First, the ports lack effective protective structures, and improper operation during the insertion and removal of fiber optic connectors can easily cause scratches on the ceramic ferrules and allow dust to enter, affecting signal transmission quality; Second, the fiber optic connectors lack a stable locking mechanism after being connected to the ports, and are easily loosened and detached due to external forces such as vibration and pulling, causing communication interruption; Therefore, it is necessary to design a pluggable wavelength division multiplexer with port wiring protection to solve the above problems.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1 Please refer to Figure 1-5 As shown, this utility model provides a pluggable wavelength division multiplexer with port wiring protection, including a multiplexer body 1, port protection components and connector locking components. The front end face of the multiplexer body 1 is provided with a mounting groove 2, and several sets of connection ports 3 are provided inside the groove 2. Multiple sets of port protection components are provided, which are hinged to one side of the mounting groove 2 and correspond one-to-one with the multiple sets of connection ports 3. A fixing seat 7 is provided on one side of the multiplexer body 1. The fixing seat 7 is connected and fixed to the multiplexer body 1 near both ends by mounting feet 8. Multiple sets of connector locking components are provided, which are all located on the top of the fixing seat 7.

[0016] Specifically, the mounting base 7 on one side of the multiplexer body 1 can support multiple sets of connector locking components. When in use, the port protection components corresponding to the connection ports 3 can be opened, and the fiber optic connectors can be inserted into the corresponding connection ports 3 inside the mounting slot 2. The corresponding connector locking components on the top of the mounting base 7 can then lock the fiber optic connectors. When not in use, the port protection components are reset and closed to protect them, thus achieving protection of the connection ports 3 and a stable connection of the fiber optic connectors. Through the above structure, the ports can be specifically protected, ensuring reliable connection of the fiber optic connectors. The overall structure is simple and has good protection and locking effects, improving the stability of the equipment.

[0017] The port protection component includes a dust cover 4 and a flexible hinge 5. One end of the dust cover 4 is hinged to one side of the mounting groove 2 via the flexible hinge 5, and the other end is engaged with the mounting groove 2. A sealing gasket 6 adapted to the connection port 3 is provided on one side of the dust cover 4. When the port protection component is working, the dust cover 4 is hinged to one side of the mounting groove 2 of the multiplexer body 1 via the flexible hinge 5. Under normal conditions, the other end of the dust cover 4 is engaged with the mounting groove 2, and the sealing gasket 6 on one side can form a seal protection against the connection port 3. When inserting the fiber optic connector, the dust cover 4 is lifted, and the connector can be connected to the connection port 3. Thus, by setting up the component, the connection port 3 can be sealed and protected, enhancing the dustproof and moisture-proof effect, avoiding port contamination or damage, and ensuring the stability of signal transmission.

[0018] The dust cover 4 is made of transparent PC material, which allows for direct observation of the cleanliness and wiring status of the connection port 3 without opening the cover, thus balancing protection and ease of use.

[0019] The connector locking assembly includes a positioning groove 9 and a pressure block 14. The top of the fixing base 7 has a positioning groove 9 corresponding to the position of the connection port 3. A threaded groove 10 is provided on one side of the positioning groove 9, and a connecting rod 11 is threadedly connected to its inner side. The end of the connecting rod 11 has a knob 12, and a connecting seat 13 is fitted around the outer ring and rotatably connected to it. The bottom of the connecting seat 13 has a pressure block 14. After the fiber optic connector is connected to the connection port 3, its outer sheath is embedded in the positioning groove 9 at the corresponding position on the top of the fixing base 7. By rotating the knob 12, it can drive the connecting rod 11 to rotate. When the connecting rod 11 is screwed into the threaded groove 10, the knob 12 can push the connecting seat 13 toward the positioning groove 9. The pressure block 14 at the bottom of the connecting seat 13 can simultaneously press the fiber optic cable to achieve a stable lock of the connector. By rotating the knob 12 in the opposite direction, the pressure block 14 loses its pressing force and can be removed from the positioning groove 9, thereby unlocking and taking out the connector. Thus, by setting it up, the connector can be effectively prevented from loosening and falling off due to external force, ensuring communication stability.

[0020] The bottom surface of the pressure block 14 is arc-shaped and is bonded with an anti-slip rubber pad. The arc-shaped design of the bottom surface of the pressure block 14 can adapt to the shape of the optical fiber. The anti-slip rubber pad can enhance the contact friction and fit, making the lock more secure and avoiding damage to the optical fiber, thus further improving the reliability of the connection.

[0021] The positioning groove 9 and the pressure block 14 are both provided with an arc-shaped guide surface 15 on one side. The arc-shaped guide surface 15 on one side of the positioning groove 9 and the pressure block 14 can prevent the optical fiber from being scratched and damaged when it is bent.

[0022] Working principle: First, the fixing seat 7, which is fixed to one side of the multiplexer body 1 by the mounting foot 8, carries multiple sets of connector locking components. When not in use, the dust cover 4 of the port protection component is engaged with the mounting groove 2 by the elastic hinge 5, and the sealing gasket 6 on one side is in contact with the connection port 3 to form a sealed protection. The transparent PC material dust cover 4 allows for direct observation of the port status. When in use, the dust cover 4 corresponding to the connection port 3 is lifted, and the fiber optic connector is guided into the corresponding connection port 3 along the positioning groove 9. Rotating the knob 12 can drive the connecting screw 11 in the threaded groove 10 to screw in, which can push the connector 13 and the pressure block 14 with anti-slip rubber pad on the bottom arc surface to press the fiber optic cable and achieve a stable lock. To unlock, rotate the knob 12 in the opposite direction to reset the pressure block 14. After the connector is pulled out, the dust cover 4 can be reset and engaged by the elastic hinge 5 to seal the connection port 3 again, thus completing the entire operation process.
