Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of optical fiber interface protection cover more specifically, the utility model relates to a kind of optical fiber interface protection cover of pre-tightness adjustable. BACKGROUND

[0002] With the development of 5G, Internet of Things and other emerging technologies, the application scenarios of optical fiber communication are continuously expanding, and the demand for optical fiber interface protection covers will continue to increase. Optical fiber interface protection covers can protect optical fiber bare fibers from physical damage. In the process of data transmission, optical fiber interfaces are susceptible to electromagnetic interference, which affects the stability and reliability of the signal. Optical fiber interface protection covers can effectively absorb and reflect electromagnetic interference, ensuring the stability of signal transmission. Optical fiber interface protection covers are widely used in data centers, telecommunications networks, enterprise networks and other fields.

[0003] After searching, the existing publication CN209858789U discloses a communication network connection accessory technical field, especially an optical fiber interface protection cover, which comprises a plastic main body, a sealing ring, a compression ring, a reed, a guide sleeve, a button, and a clasp. The compression ring is provided with an assembly groove. The guide sleeve and the button are provided with a clamping groove. The button is connected with the inner wall of the guide sleeve and presses the reed. The inner wall of the plastic main body is also provided with a first assembly cavity and a second assembly cavity. The second assembly cavity is also provided with an inner clamping groove. The structure design is reasonable. The protection cover arranged on the optical fiber interface can effectively isolate the internal and external environment of the optical fiber interface, prevent dust from entering, and thus protect the interface between the two optical fibers. Moreover, the reed arranged on the compression ring port can prevent the interface from being pulled off, improve the resistance of optical fiber connection, and the plastic main body uses high-strength material, which can withstand underground and underwater pressure and acid and alkali corrosion, effectively protect the connection performance of the optical fiber, and the installation and disassembly are fast and convenient.

[0004] The existing optical fiber interface protection cover has poor sealing performance and is prone to water ingress. Long-term water ingress into the optical cable can increase the attenuation of the optical fiber. This is because the optical fiber is composed of glass silicon-oxygen tetrahedrons connected to each other. In a water environment, water vapor will attach to the glass surface and then slowly undergo hydrolysis reaction, causing the silicon-oxygen bond to break and causing glass cracks, which increases the scattering of light transmission and thus increases the loss. Moreover, contact between the optical fiber bare fiber and water can change the refractive index of the optical fiber, which affects the transmission path and mode distribution of light, causing transmission deviation and distortion of optical signals. The traditional optical fiber interface protection cover cannot limit the optical fiber according to the number of optical fibers, so the position of the optical fiber in the interface is not fixed. The position of the optical fiber in the interface changes the bending radius and stress of the optical fiber, which affects the transmission quality of the optical signal and causes signal transmission to exhibit instability such as attenuation and distortion.

[0005] Therefore, the pre-tightness adjustable optical fiber interface protection cover is provided for the above problems. Contents of the utility model

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.

[0023] Example 1

[0024] As attached Figures 1 to 6 The optical fiber interface protective cover with adjustable pretension shown includes a limiting component 1, a housing component 2, and a moisture-proof component 3. The limiting component 1 is placed on the upper part of the inner wall of the housing component 2, and the moisture-proof component 3 is installed on the side of the housing component 2. The limiting component 1 includes a first limiting bolt 4, a first limiting half ring 5, a second limiting bolt 6, and a second limiting half ring 7. The first limiting half ring 5 is installed on the side of the first limiting bolt 4, the second limiting half ring 7 is placed on the side of the first limiting half ring 5 away from the first limiting bolt 4, and the second limiting bolt 6 is installed on the side of the second limiting half ring 7 away from the first limiting bolt 4.

[0025] The structure includes: a limiting component 1 that limits the optical fiber inside the fiber optic interface protective cover; a housing component 2 that provides space for the optical fiber and protects it; a moisture-proof component 3 that prevents moisture from entering the external interface 15; a limiting component 1 placed on the upper inner wall of the housing component 2; a moisture-proof component 3 bolted to the side of the housing component 2; a limiting component 1 comprising a first limiting bolt 4, a first limiting half-ring 5, a second limiting bolt 6, and a second limiting half-ring 7; the first limiting bolt 4 and the second limiting bolt 6 can be screwed to push the first limiting half-ring 5 and the second limiting half-ring 7 to limit the optical fiber; the first limiting half-ring 5 welded to the side of the first limiting bolt 4; the second limiting half-ring 7 placed on the side of the first limiting half-ring 5 away from the first limiting bolt 4; and the second limiting bolt 6 welded to the side of the second limiting half-ring 7 away from the first limiting bolt 4. When placing the optical fiber interface into the fiber optic interface protective cover, the worker needs to insert the optical fiber into the cover and then... Tightening the limiting bolts restricts the optical fiber in the limiting component 1. The worker tightens the first limiting bolt 4 and the second limiting bolt 6, causing them to push the first limiting half-ring 5 and the second limiting half-ring 7 to limit the internal optical fiber. After being limited, the optical fiber will not shift or collide with each other due to external vibrations, ensuring transmission efficiency. The limiting component 1 can be manually adjusted according to the number of optical fibers. After the optical fibers are fixed, the worker needs to check the moisture-proof component 3. To determine whether the desiccant beads can continue to be used, when inspecting the desiccant beads inside the desiccant component 3, the worker needs to open the desiccant cover 12 from the desiccant box 11. A fixing component 13 is installed on one side of the desiccant box 11. The worker only needs to press the trigger button 17, which will press down the protrusion of the desiccant cover 12, allowing the desiccant cover 12 to slide off from the side of the desiccant box 11. After the desiccant cover 12 is removed, the spring 19 will pull the trigger button 17 back to its original position through the second connecting plate 18, restoring the trigger button 17 to its original position.

[0026] Example 2

[0027] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 6 As shown below, see details:

[0028] In a preferred embodiment, the electromagnetic interference shielding layer 8 can prevent external signals from affecting the transmission of optical fiber information, the waterproof layer 9 can prevent external water sources from affecting the optical fiber, and the external interface component 10 can connect the optical fiber and the internal network cable. The waterproof layer 9 is installed on the outer wall surface of the electromagnetic interference shielding layer 8 by welding, and the external interface component 10 is installed on the side of the waterproof layer 9 by bolts.

[0029] In a preferred embodiment, the moisture-proof component 3 includes a moisture-proof box 11, a moisture-proof cover 12, and a fixing component 13. The moisture-proof box 11 provides space for placing the moisture-proof beads. The moisture-proof cover 12 can form a closed space with the moisture-proof box 11.

The moisture-proof cover 12 is placed on the side of the moisture-proof box 11, and the fixing component 13 is placed on the side of the moisture-proof box 11 away from the moisture-proof cover 12.

[0030] In a preferred embodiment, the external interface assembly 10 includes a protective shell 14, an external interface 15, and a first connecting plate 16. The protective shell 14 can provide a space for bare optical fibers to pass through and protect them. The external interface 15 can connect the optical fiber to an external network cable. The first connecting plate 16 connects the moisture-proof box 11 and the external interface assembly 10. The external interface 15 is bolted to the side of the protective shell 14, and the first connecting plate 16 is bolted to the side of the protective shell 14 away from the external interface 15.

[0031] In a preferred embodiment, the fixing component 13 includes a trigger button 17, a second connecting plate 18, and a spring 19. The trigger button 17 can control the limiting position of the fixing component 13 on the moisture cover 12. The second connecting plate 18 connects the spring 19 and the trigger button 17. The spring 19 can pull the trigger button 17 back to its original position. The second connecting plate 18 is bolted to the outer diameter surface of the trigger button 17. The spring 19 is welded to the side of the second connecting plate 18 away from the trigger button 17.

[0032] The working process of this utility model is as follows: First, when the fiber optic interface is to be placed into the fiber optic interface protective cover, the worker needs to first put the fiber optic cable into the fiber optic interface protective cover, and then tighten the limiting bolts to limit the fiber optic cable by the limiting component 1. The worker tightens the first limiting bolt 4 and the second limiting bolt 6, so that the first limiting bolt 4 and the second limiting bolt 6 push the first limiting half ring 5 and the second limiting half ring 7 to limit the fiber optic cable inside. After the fiber optic cable is limited, it will not be displaced or collide with each other due to external vibration, thus ensuring transmission efficiency. The limiting component 1 can be manually adjusted according to the number of fiber optic cables. After the fiber optic cable is fixed, the worker needs to check whether the desiccant beads in the desiccant component 3 can still be used. When checking the desiccant beads inside the desiccant component 3, the worker needs to open the desiccant cover 12 from the desiccant box 11. A fixing component 13 is installed on one side of the desiccant box 11. The worker only needs to press the trigger button 17.

[0033] Trigger button 17 will press down the protrusion of moisture cover 12, allowing moisture cover 12 to slide off from the side of moisture box 11. After moisture cover 12 is removed, spring 19 will pull trigger button 17 back to its original position via second connecting plate 18, restoring trigger button 17 to its original position. The waterproof layer 9 of the fiber optic interface protective cover housing assembly 2 can prevent external water sources from entering the fiber optic interface protective cover, while its anti-electromagnetic interference layer 8 can prevent external signals from interfering with fiber optic transmission. Its external interface assembly 10 can connect the fiber optic cable and the internal network cable. The external interface assembly 10 includes a protective shell 14, an external interface 15, and a first connecting plate 16. The protective shell 14 can provide a space for bare fiber optic cables to pass through and protect them. The external interface 15 can connect the fiber optic cable and the external network cable. The first connecting plate 16 connects the moisture box 11 and the external interface assembly 10. The above is the working principle of this type of fiber optic interface protective cover with adjustable pretension.
