Description

Technical Field

[0002] Fiber optic connectors are optical devices used to achieve detachable mechanical connection and optical alignment between two or more optical fibers to ensure stable transmission of optical signals.

[0003] Existing fiber optic connectors for network engineering have complex assembly structures and cumbersome operation steps, requiring multiple alignments and fixations, making rapid assembly difficult. In large-scale construction scenarios, this significantly reduces construction efficiency, greatly increases labor and time costs, and has poor sealing performance. In outdoor rainy, dusty, or humid environments, they cannot effectively prevent moisture and dust from entering. Moisture can easily cause internal optical components to become damp and oxidized, while dust accumulation can wear down the fiber end face, form impurities that obstruct the optical path, and thus seriously affect the quality of optical signal transmission, shorten the connector's lifespan, and fail to meet the high-efficiency and stable application requirements of network engineering. Summary of the Invention

[0004] In view of the problems existing in the current fiber optic connector for network engineering, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a fiber optic connector for network engineering, which solves the problems of existing fiber optic connectors for network engineering being inconvenient to quickly assemble with optical fibers, and having poor sealing performance that makes them prone to water and dust ingress, affecting their performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fiber optic connector for network engineering includes a connector comprising a male connector end and a female connector end. One end of both the male and female connector ends is threadedly connected to a connecting sleeve.

The inner side wall of the threaded locking sleeve is slidably connected to a sealing elastic sleeve. An inclined pressing surface is provided on the inner side wall of one end of the connecting sleeve, and the sealing elastic sleeve engages with the inclined pressing surface.

[0008] The male connector includes a first protective sleeve, and the female connector includes a second protective sleeve.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses an optical fiber connector for network engineering.

[0027] This utility model provides, for example Figure 1-4 The fiber optic connector for network engineering shown includes a connector 1, which includes a male connector 2 and a female connector 3. One end of both the male connector 2 and the female connector 3 is threadedly connected to a connecting sleeve 4. The outer wall of one end of the connecting sleeve 4 is threadedly connected to a threaded locking sleeve 5. The inner wall of the threaded locking sleeve 5 is slidably connected to a sealing elastic sleeve 6. An inclined pressing surface 7 is provided on the inner wall of one end of the connecting sleeve 4. The sealing elastic sleeve 6 is engaged with the inclined pressing surface 7.

[0028] The male connector 2 includes a first protective sleeve 8, and the female connector 3 includes a second protective sleeve 9. Each of the first and second protective sleeves 8 and 9 has a limiting interface 10 at one end, which engages with a limiting protective sleeve 11. One end of each limiting protective sleeve 11 is threadedly connected to a first ceramic guide core 12 and a second ceramic guide core 13, respectively. The first and second ceramic guide cores 12 and 13 are interlocked. A sealing locking mechanism is provided between the first and second protective sleeves 8 and 9. Using the connecting sleeve 4 and threaded locking sleeve 5, quick screwing and assembly can be achieved, making operation simple. The sealing elastic sleeve 6 cooperates with the inclined pressing surface 7. When the threaded locking sleeve 5 is tightened, the sealing elastic sleeve 6 is compressed and deformed, tightly fitting the fiber surface, thus achieving optical... The rapid fixation of the fiber optic cable forms a reliable seal, preventing dust and moisture from entering the connector and improving connection stability. The snap-fit ​​structure between the limit card interface 10 and the limit protective sleeve 11 facilitates quick installation and removal of the limit protective sleeve 11, making it convenient for the inspection and replacement of the ceramic guide core. The first ceramic guide core 12 and the second ceramic guide core 13 are made of ceramic material, which has high precision and low loss characteristics. Their plug-in cooperation ensures efficient transmission of fiber optic signals. At the same time, the threaded connection method facilitates accurate positioning and rapid assembly, improving connection efficiency. This solves the problems of existing fiber optic connectors used in network engineering, such as inconvenience in quick assembly with fiber optics and poor sealing that makes them susceptible to water and dust ingress, affecting their performance.

[0029] To achieve a sealing effect while making a quick connection, such as Figure 1 and 2 As shown, the sealing and locking mechanism includes a sealing socket 14, a sealing ring 15, a sliding groove 16, and a bolt limiting sleeve 17. One end of the first protective sleeve 8 has a sealing socket 14, and one end of the second protective sleeve 9 is fixedly connected to the sealing ring 15. The sealing ring 15 and the sealing socket 14 are inserted into each other. The side wall of the second protective sleeve 9 has a sliding groove 16, and the bolt limiting sleeve 17 is slidably connected thereto. The inner side wall of the bolt limiting sleeve 17 is threadedly connected to the outer side wall of the first protective sleeve 8. By using the insertion and cooperation of the sealing ring 15 and the sealing socket 14, a first sealing barrier is formed. By using the sliding bolt limiting sleeve 17 and tightening it, the first protective sleeve 8 and the second protective sleeve 9 can be further compressed, which significantly improves the sealing effect and effectively prevents moisture and dust from entering. This structure is easy to disassemble and assemble, and facilitates the maintenance and repair of the connector.

[0030] To achieve both buffering protection and dehumidification, such as Figure 2 and 3 As shown, the limiting protective sleeve 11 includes a limiting ring 18, and a porous silicone protective tube sleeve 19 is fixedly connected to the inner side wall of the limiting ring 18. A molecular sieve dehumidifying filler 20 is fixedly connected inside the cavity of the porous silicone protective tube sleeve 19. The porous silicone protective tube sleeve 19 has good flexibility and elasticity, which can tightly wrap the optical fiber, provide physical protection, and prevent the optical fiber from being damaged by external forces. The molecular sieve dehumidifying filler 20 can adsorb the moisture that enters the limiting protective sleeve 11, maintain the internal dry environment, avoid the degradation of optical fiber transmission performance due to moisture, and further improve the environmental adaptability and reliability of the connector.

[0031] To facilitate precise docking and enhance sealing, such as Figure 2-4 As shown, one end of the first ceramic conductor 12 has a docking slot 21 and a first matching gel ring 22 is fixedly connected thereto. One end of the second ceramic conductor 13 is fixedly connected to a ceramic docking ring 23 and a second matching gel ring 24. The ceramic docking ring 23 is inserted into the docking slot 21, and the first matching gel ring 22 and the second matching gel ring 24 are inserted into each other. By using the insertion structure of the docking slot 21 and the ceramic docking ring 23, the precise docking between the ceramic conductors is ensured, reducing signal transmission loss. By using the insertion cooperation of the first matching gel ring 22 and the second matching gel ring 24, the gaps are further filled, the sealing is enhanced, and dust and moisture are prevented from entering the docking part, ensuring the stable transmission of optical fiber signals.

[0032] To achieve thermal insulation protection, such as Figure 2 As shown, the first protective sleeve 8 and the second protective sleeve 9 are provided with an aerogel thermal insulation filling layer 25. The aerogel thermal insulation filling layer 25 has excellent thermal insulation performance, which can effectively isolate the influence of external temperature changes on the inside of the connector, avoid changes in the performance of optical fiber materials due to temperature fluctuations, ensure that the optical fiber connector can work stably in different temperature environments, and expand its application range.

[0033] To achieve rust prevention, corrosion protection, and cushioning protection, such as Figure 1 and 2 As shown, the surface and interior of connector 1 are coated with rust-proof and corrosion-proof coatings. The inner walls of the threaded locking sleeves 5 at both ends are fixedly connected with inner conical rubber buffer rings 26. The rust-proof and corrosion-proof coating can effectively prevent the metal parts of the connector from rusting and corroding, thus extending the service life of the connector. When the threaded locking sleeves 5 are tightened, the inner conical rubber buffer rings 26 can evenly compress the optical fiber, providing buffer protection and preventing the optical fiber from being damaged due to excessive compression. At the same time, it further enhances the sealing effect and prevents external impurities from entering the interior of the connector.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
