Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber hardware, in particular to an optical fiber hardware with a pressure self-regulating function. Background Art

[0002] In modern fiber-optic communication networks, fiber optic fittings are key components for connecting and securing optical cables. Their performance directly impacts the stability and reliability of communications. Traditional fiber optic fittings are often designed with a relatively fixed structure, making them less adaptable to cables of varying diameters. When encountering cables whose diameters do not match the fitting's pre-set specifications, achieving effective compression and securing is difficult. Too loose a fixation cannot effectively resist external pulling forces and vibrations, easily causing the cable to loosen or even fall off, leading to communication interruptions. On the other hand, too tight a fixation can cause physical damage to the cable, compromising the signal transmission quality of the optical fiber.

[0003] Furthermore, traditional fiber optic fittings also present numerous problems in complex and changing external environments. For example, under varying climate conditions, optical cables can expand and contract due to thermal expansion and contraction, causing length changes. Traditional fittings struggle to automatically adapt to these changes, causing changes in pressure between the fitting and the cable, impacting connection stability. Furthermore, in areas subject to frequent wind-induced vibration, traditional fittings are unable to effectively mitigate the effects of wind on the cable. Long-term wind-induced vibration can easily cause fatigue damage to the cable, significantly shortening its service life.

[0004] During the fiber optic connection process, the fiber connectors of traditional fiber optic fittings also lack adaptive adjustment capabilities. When the optical cable is shaken by external forces, the fiber optic connection is easily affected, and problems such as misalignment and loosening may occur, seriously affecting the quality of the fiber optic connection and the reliability of communication. In view of these obvious deficiencies in the adaptive capabilities of traditional fiber optic fittings, the present invention proposes a fiber optic fitting with excellent adaptive capabilities to effectively solve these problems and improve the overall performance of fiber optic communication networks. Summary of the Invention

[0005] In order to solve the problem that traditional optical fiber fittings are difficult to adapt to optical cables of different diameters, changes in the external environment and external force interference due to their fixed structure, resulting in poor optical cable fixation and susceptibility to damage, which in turn affects the quality of optical fiber connection and communication stability, the purpose of the present invention is to provide an optical fiber fitting with pressure self-regulating function.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an optical fiber fitting with a pressure self-adjusting function, comprising a rectangular frame, two symmetrically arranged strip blocks hinged at the bottom of the rectangular frame, a compression block and an adaptive pressure plate installed in the strip blocks, the compression block and the adaptive pressure plate are jointly used to compress the optical cable; a tension spring is jointly hung between the top of the strip block and the top of the rectangular frame, and an optical fiber connector is installed in the middle of the rectangular frame for connecting the two optical fiber ends.

[0007] Preferably, a fixed block is fixedly provided at the bottom of the rectangular frame, a U-shaped opening is opened at the bottom of the strip block, and the inner wall of the U-shaped opening is hinged to the two sides of the fixed block; a fixed plate is fixedly connected to the top of the rectangular frame, the side wall of the fixed plate is fixedly connected to the first hanging rod, a U-shaped opening is opened at the top of the strip block, and the inner wall of the U-shaped opening is fixedly connected to the second hanging rod, and the two ends of the tension spring are respectively hung with the first hanging rod and the second hanging rod.

[0008] Preferably, a rectangular through-hole is provided on the side wall of the strip block, a guide groove is provided on the top of the rectangular through-hole, and a slider is slidably sleeved on the inner wall of the guide groove and is fixedly connected to the clamping block; the top of the slider is threadedly connected to a screw rod, which rotates through the top of the guide groove and extends to the U-shaped opening at the top of the strip block; the top of the screw rod is fixedly connected to a disc.

[0009] Preferably, a mounting groove is provided inside the strip block below the rectangular through-hole, and a guide block fixedly connected to the bottom of the adaptive pressure plate is slidably connected between the top of the mounting groove and the rectangular through-hole. The bottom of the guide block is T-shaped, and the top surface of the T-shaped end is connected to the inner side of the top port of the mounting groove; an electric push rod is fixedly installed at the bottom of the mounting groove, and the telescopic end of the electric push rod is fixedly connected to a push plate, and a pressure sensor is embedded in the top of the push plate, and a first spring is installed between the monitoring end of the pressure sensor and the bottom of the guide block.

[0010] Preferably, the optical fiber connector includes a U-shaped frame fixedly arranged on the top of the fixed block, a T-shaped rod is vertically slidably connected to the top of the U-shaped frame, the top of the T-shaped rod is fixedly connected to an optical fiber groove, a U-shaped clamping cover is fastened to the port of the optical fiber groove by a snap, and the bottom of the U-shaped clamping cover has a vertical protrusion for clamping the optical cable; a second spring is provided on the outer wall of the T-shaped rod, and the two ends of the second spring are respectively pressed against the bottom of the optical fiber groove and the top of the U-shaped frame.

[0011] Compared with the prior art, the present invention achieves the following beneficial effects:

[0012] 1. Precise Pressure Regulation: The electric actuator and pressure sensor work together to monitor and automatically adjust the compression pressure on the optical cable in real time. When the pressure is too high, the actuator retracts appropriately to reduce the pressure; when the pressure is too low, the actuator continues to extend to increase the pressure. This precise self-regulating pressure function ensures that the optical cable is securely compressed while preventing damage caused by improper pressure, greatly improving the reliability and stability of the optical cable connection.

[0013] 2. Good adaptability: The strip block is connected to the top of the rectangular frame via a tension spring and can be adjusted within a certain range. When facing optical cables of different diameters or changes in the external environment, it can automatically adjust its position to ensure effective compression of the optical cable, enhancing the versatility and adaptability of the optical fiber fittings.

[0014] 3. Convenient installation and adjustment: The design of the screw and disc of the compression block allows the operator to easily rotate the disc and adjust the position of the compression block in the rectangular through-hole to achieve initial compression of the optical cable. The operation is simple and efficient, reducing the difficulty and workload of installation.

[0015] 4. Excellent wind-vibration resistance: The presence of the tension spring enables the optical cable on the strip block to buffer and offset part of the wind force through the swing of the strip block under external interference such as wind vibration, effectively reducing the impact of wind vibration on the optical cable, improving the optical cable's wind-vibration resistance in harsh environments, and ensuring the stability of optical fiber communication.

[0016] 5. Reliable fiber connection protection: In the fiber optic connector, the fiber trough is connected to the U-shaped frame via a T-bar and cushioned by a second spring. During the fiber optic connection process, even if the optical cable shakes or is subjected to external forces, the fiber trough can move up and down under the action of the second spring, effectively preventing damage to the fiber connection caused by excessive external forces, ensuring the quality and stability of the fiber optic connection.

[0017] 6. Stable overall structure: The fixing blocks, fixing plates and other components inside the rectangular frame cooperate with each other to provide a stable installation foundation for other components, making the entire fiber optic fitting structure stable. The various components work together to ensure the normal operation of the product in various environments. BRIEF DESCRIPTION OF THE DRAWINGS

Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0025] The present invention provides a technical solution: a fiber optic fitting with a self-regulating pressure function, primarily comprising a rectangular frame 1 forming a basic framework. A fixing block 101 is fixedly mounted at the bottom of the rectangular frame 1, providing a mounting base for subsequent components. A fixing plate 102 is fixedly connected to the top of the rectangular frame 1, and a first hanging rod 103 is fixedly connected to the sidewall of the fixing plate 102.

[0026] The strip block 2 is symmetrically arranged with two U-shaped openings at its bottom. The inner walls of the U-shaped openings are hingedly connected to the two sides of the fixed block 101, thus enabling the strip block 2 to be rotatably connected to the bottom of the rectangular frame 1. The top of the strip block 2 has a U-shaped opening, and the inner wall of the U-shaped opening is fixedly connected to the second hanging rod 201. The ends of the tension spring 5 are respectively connected to the first hanging rod 103 and the second hanging rod 201. The tension spring 5 exerts an upward force on the strip block 2, maintaining it in a fixed position.

[0027] A rectangular through-hole 202 is provided on the side wall of the strip block 2, and a guide groove is provided at the top of the rectangular through-hole 202. The pressing block 3 is connected to the guide groove via a slider 301. The slider 301 is fixedly connected to the pressing block 3, and the slider 301 can slide in the guide groove. The top of the slider 301 is threadedly connected to a screw rod 302, which rotates through the top of the guide groove and extends to the U-shaped opening at the top of the strip block 2. A disc 303 is fixedly connected to the top of the screw rod 302. By rotating the disc 303, the screw rod 302 can be driven to rotate. Since the screw rod 302 is threadedly connected to the slider 301, the position of the pressing block 3 in the rectangular through-hole 202 can be adjusted.

[0028] The strip block 2 has a mounting slot 203 defined within it, located below the rectangular through-hole 202. The adaptive pressure plate 4 is connected to the mounting slot 203 via a guide block 401. The guide block 401 is fixedly connected to the bottom of the adaptive pressure plate 4 and slides between the top of the mounting slot 203 and the rectangular through-hole 202. The bottom of the guide block 401 is T-shaped, with the top surface of the T-shaped end engaging the inner side of the top end of the mounting slot 203 to prevent the guide block 401 from dislodging. An electric push rod 402 is fixedly mounted at the bottom of the mounting slot 203. The telescopic end of the push rod 402 is fixedly connected to a push plate 403. A pressure sensor is embedded in the top of the push plate 403, and a first spring 404 is installed between the monitoring end of the pressure sensor and the bottom of the guide block 401. The push rod 402 can extend and retract to push the push plate 403, thereby applying pressure to the guide block 401 and the adaptive pressure plate 4 via the first spring 404. The pressure sensor can monitor the pressure in real time.

[0029] The optical fiber connector 6 includes a U-shaped frame 601 fixedly mounted on the top of the fixed block 101. A T-shaped rod 602 is vertically slidably connected to the top of the U-shaped frame 601. A fiber optic groove 603 is fixedly connected to the top of the T-shaped rod 602. The fiber optic groove 603 is used to place the optical fiber cable. A U-shaped compression cover 604 is fastened to the end of the fiber optic groove 603 by a snap. The bottom of the U-shaped compression cover 604 has a vertical protrusion that can be used to compress the optical fiber cable. The outer wall of the T-shaped rod 602 is provided with a second spring 605. The two ends of the second spring 605 are respectively pressed against the bottom of the fiber optic groove 603 and the top of the U-shaped frame 601. The second spring 605 can buffer and regulate the fiber optic groove 603.

[0030] Working process:

[0031] Installation and initial compression of the optical cables: First, secure the rectangular frame 1. Pass the two optical cables through the two rectangular holes 202 of the two strip blocks 2. Adjust the positions of the compression blocks 3 and adaptive pressure plates 4 on the two strip blocks 2. Rotate the circular plate 303 to move the compression block 3 downward to the appropriate position, initially compressing the optical cables. Place the optical fibers at the ends of the two optical cables in the fiber slots 603 and heat-seal them. Then, close the U-shaped compression cover 604, using the protrusions on its bottom to initially secure the cables.

[0032] During wind-induced vibration of the optical cable, adaptive pressure regulation is implemented: The electric push rod 402 is activated, pushing the push plate 403 upward. The push plate 403, via the first spring 404, pushes the guide block 401 and the adaptive pressure plate 4 upward, further compressing the optical cable. During this process, a pressure sensor monitors the pressure in real time. If the pressure is too high, the push rod 402 retracts appropriately to reduce the pressure. If the pressure is too low, the push rod 402 continues to extend, increasing the pressure, thereby achieving self-regulation of the cable's compression pressure.

[0033] The presence of the tension spring 5 can make the optical cable on the strip block 2 have a better wind vibration resistance effect.

[0034] Buffering and adjustment during optical fiber connection: When connecting two optical fiber ends, since the optical cable may have a certain degree of shaking or external force, the optical fiber groove 603 can move up and down under the action of the second spring 605, playing a buffering role, avoiding damage to the optical fiber connection part due to excessive external force, and ensuring the stability and reliability of the optical fiber connection.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
