Description

Technical Field

[0001] This invention belongs to the field of optical fiber communication technology, specifically a passive optical component. Background Technology

[0002] Passive optical components are optical elements used in optical communication and fiber optic networks that do not require an external power source to operate. They are typically used to process optical signals, such as distribution, combining, coupling, attenuation, and filtering. Passive optical components are widely used in various aspects of fiber optic communication, data centers, local area networks, metropolitan area networks, long-distance communication, and optical networks. They play an important role in improving the performance of optical communication systems, expanding system capacity, and reducing costs.

[0003] Fiber optic adapters are key passive components in fiber optic networks used to align two fiber optic connectors. Their core is the internal pre-cast sleeve, which is used to precisely align the pre-cast ferrules of the two connectors. When the fiber optic connectors are repeatedly plugged and unplugged, the end faces of the pre-cast ferrules will experience direct mechanical friction and collision, resulting in tiny scratches on the end faces. This increases the insertion loss and return loss of the optical signal. Long-term wear leads to unstable connection performance, requiring frequent cleaning or replacement. Therefore, improvements are needed. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a passive optical component, comprising a connector assembly, wherein an optical fiber body is disposed on one side of the connector assembly, and an mounting assembly is disposed on the outer wall of the optical fiber body; the connector assembly includes a connector body, an interface component body is movably connected to the end of the connector body near the optical fiber body, a filter and a detector are disposed in the inner cavity of the connector body, a connection unit is fixedly installed in the inner cavity of the connector body near the interface component body, a fixing unit is disposed at the end of the connector body, a moving unit is disposed in the interface component body near the fixing unit, the connection unit includes a fixing post, a connecting post is movably connected to the inner cavity of the fixing post, a spring is elastically connected between the connecting post and the connector body, an arc-shaped component is fixedly installed at the end of the connecting post, and a movable block is movably connected to the lower end of the arc-shaped component.

[0006] Preferably, the fixing unit includes a second spring, and a pin is fixedly installed at the end of the second spring. The moving unit includes a spring telescopic rod, and a moving block is fixedly installed at the end of the spring telescopic rod. A telescopic component is provided on the interface body near the moving block. The spring telescopic rod is fixedly connected to the interface body.

[0007] Preferably, the mounting assembly includes a bottom base plate, a mounting plate is movably connected to the top surface of the bottom base plate, a movable member is movably connected to the lower end of the bottom base plate, a connecting rope is fixedly installed at the end of the movable member, and a limit ring is fixedly installed at the end of the connecting rope.

[0008] Preferably, the movable block is configured as an I-shaped part, and the lower end of the arc-shaped part is provided with a groove, and the inner wall of the groove is smooth.

[0009] Preferably, the connecting unit is provided in four groups, the four groups of connecting units are the same in shape and size, and the four groups of connecting units form a circle.

[0010] Preferably, the end of the spring away from the interface body is fixedly connected to the connector body, the upper end of the pin has a groove, and the pin is movably connected to the moving block.

[0011] Preferably, the spring telescopic rod is fixedly connected to the interface body, the two sides of the moving block are set as inclined surfaces, the upper end of the moving block is provided with a through groove, and the telescopic component is movably connected to the through groove.

[0012] Preferably, the movable component has limit blocks on both sides, the bottom base plate has a limit groove at its lower end, and the bottom base plate has an isolation groove at its upper end.

[0013] Preferably, the limiting ring is made of rubber, and a groove is provided at the upper end of the limiting ring, and the limiting ring is movably connected to the optical fiber body.

[0014] Preferably, the connector body and the interface body are made of stainless steel, and the interface body has a guide groove at the end near the second spring, and the guide groove is movably connected to the pin.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes a combination of arc-shaped components and movable blocks to align the finished ferrule with the movable block. This causes the movable block to press against the connecting post and spring, moving outward to accommodate ferrules of different sizes. The arc-shaped components and movable blocks further support the finished ferrule, ensuring precise alignment of the optical fiber inside the ferrule and reducing displacement caused by vibration or external forces. This improves connection stability, and the fixing measures keep the ferrule in the correct position, preventing poor contact due to instability. This achieves the effect of reducing wear, enhancing connection performance, and eliminating the need for frequent cleaning or replacement.

[0016] This invention, through the cooperation of structures such as a spring telescopic rod and a pin, allows the spring telescopic rod to engage with the pin, aligning the pin with the guide groove. This prevents the end face of the finished ferrule from rubbing and colliding with the connector body, thus avoiding scratches on the surface of the finished ferrule. Scratches can lead to a decrease in coupling efficiency between the optical fiber and the ferrule, resulting in additional losses in optical signal transmission, increasing insertion loss, and affecting the overall system transmission performance.

[0017] This invention, through the cooperation of structures such as connecting ropes and limiting rings, moves the connecting ropes and limiting rings, thereby fixing and limiting the optical fiber body. Limiting the optical fiber body can effectively prevent the optical fiber from moving or deviating during use, thus maintaining the stability of the optical path and reducing signal loss.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 7 As shown, the present invention provides a passive optical component, including a connector assembly 1. An optical fiber body 2 is disposed on one side of the connector assembly 1, and a mounting assembly 3 is disposed on the outer wall of the optical fiber body 2. The connector assembly 1 includes a connector body 11, an interface body 12 is movably connected to the end of the connector body 11 near the end of the optical fiber body 2, a filter 13 and a detector 14 are disposed within the cavity of the connector body 11, a connection unit 15 is fixedly mounted within the cavity of the connector body 11 near the interface body 12, a fixing unit 16 is disposed at the end of the connector body 11, and a moving unit 17 is disposed within the interface body 12 near the fixing unit 16. The connection unit 15 includes a fixing post 151, a connecting post 152 is movably connected to the cavity of the fixing post 151, and the connecting post 152 and the connector body 11 are elastically connected. The assembly includes a spring 153, an arc-shaped component 154 fixedly installed at the end of the connecting column 152, a movable block 155 movably connected to the lower end of the arc-shaped component 154, a fixing unit 16 including a spring 161, a pin 162 fixedly installed at the end of the spring 161, a moving unit 17 including a spring telescopic rod 171, a movable block 172 fixedly installed at the end of the spring telescopic rod 171, a telescopic component 173 provided near the movable block 172 on the interface body 12, the spring telescopic rod 171 fixedly connected to the interface body 12, and an installation assembly 3 including a bottom base plate 31, an installation plate 32 movably connected to the top surface of the bottom base plate 31, a movable component 33 movably connected to the lower end of the bottom base plate 31, a connecting rope 34 fixedly installed at the end of the movable component 33, and a limit ring 35 fixedly installed at the end of the connecting rope 34.

[0022] Using the above scheme: Through the cooperation of connector assembly 1 and mounting assembly 3, the finished ferrule is first connected to the interface body 12. When the guide groove of the interface body 12 is connected to the pin 162, the interface body 12 moves towards the connector body 11, compressing the pin 162 and the second spring 161, causing the second spring 161 to retract. When it can no longer move, the spring telescopic rod 171 engages with the pin 162, aligning the pin 162 with the guide groove, so that the interface body 12 drives the finished ferrule towards the connector body. When the finished ferrule moves within the inner cavity of connector body 11, the end face of the finished ferrule will not rub or collide with the connector body 11, thus avoiding scratches on the surface of the finished ferrule. This prevents scratches from reducing the coupling efficiency between the optical fiber and the ferrule, causing additional losses in the optical signal transmission process, increasing insertion loss, and affecting the overall system transmission performance. As the finished ferrule moves gradually, it aligns with the movable block 155, causing the movable block 155 to press the connecting post 152 and spring 153 outwards, thereby adapting to finished ferrules of different sizes. The movement is then complete. Subsequently, spring 153 drives connecting post 152, arc-shaped component 154, and movable block 155 to further support the finished ferrule, ensuring precise alignment of the optical fiber inside the ferrule, reducing displacement caused by vibration or external force, thereby improving connection stability. The fixing measures keep the ferrule in the correct position, avoiding poor contact due to instability. After fixing the finished ferrule, one end of the optical fiber body 2 is connected to the interface component body 12, and the other end is placed on the surface of the bottom substrate 31. The bottom substrate 31 has an isolation groove design at the upper end, allowing for optical fiber isolation. To effectively prevent crosstalk between adjacent optical fibers, ensure signal independence between channels, and improve signal quality, the movable part 33 is pulled to move the connecting rope 34 and the limiting ring 35. The cooperation of the limiting groove and the limiting block limits the movable part 33, making the movement of the movable part 33 more stable. The movable part 33 moves the connecting rope 34 and the limiting ring 35, so that the limiting ring 35 fixes and limits the optical fiber body 2. Limiting the optical fiber body 2 can effectively prevent the optical fiber from moving or deviating during use, thereby maintaining the stability of the optical path and reducing signal loss.

[0023] like Figure 2 , Figure 3 As shown, the movable block 155 is set in the shape of an I-beam, and the lower end of the arc-shaped part 154 is provided with a groove, and the inner wall of the groove is smooth. There are four sets of connecting units 15, and the four sets of connecting units 15 are the same in shape and size, and the four sets of connecting units 15 form a circle.

[0024] The above solution employs the following design: The I-beam design of the movable block 155 allows it to fit more closely to the outer wall of the finished ferrule, thus providing better support. This ensures precise alignment of the optical fiber within the ferrule, reducing displacement caused by vibration or external forces, thereby improving connection stability. The fixing mechanism keeps the ferrule in the correct position, preventing poor contact due to instability. It effectively withstands external forces, enhancing the overall structural mechanical strength and reducing the risk of breakage or damage to the finished ferrule under stress. It also helps reduce reflection and scattering, improving return loss and enhancing overall system performance. The lower end of the arc-shaped component 154 is movably connected to the movable block 155. After the finished ferrule is fixed, if the finished ferrule needs to be rotated, the movable block 155 can rotate, thereby avoiding scratches on the surface of the finished ferrule. The design of four sets of connecting units 15 allows them to form a circle, which can better fix the finished ferrule. The bottom surface of the movable block 155 can better fit the finished ferrule. The design of the four connecting units 15 being the same size and shape can better facilitate quick positioning and alignment during assembly, reducing assembly time and operation difficulty. The circular design with the same size and shape can effectively disperse stress and avoid stress concentration, thereby reducing the risk of damage to the optical fiber or ferrule.

[0025] like Figure 2 , Figure 6 As shown, the end of spring 161 furthest from the interface body 12 is fixedly connected to the connector body 11. The upper end of pin 162 has a groove. Pin 162 is movably connected to moving block 172. Spring telescopic rod 171 is fixedly connected to interface body 12. The two sides of moving block 172 are set as inclined surfaces. The upper end of moving block 172 has a through groove. Telescopic member 173 is movably connected to the through groove. The connector body 11 and interface body 12 are made of stainless steel. The end of interface body 12 near spring 161 has a guide groove, and the guide groove is movably connected to pin 162.

[0026] The above solution is adopted: Through the cooperation of spring 161 and connector body 11, spring 161 and connector body 11 are fixedly connected. When the guide groove of interface body 12 is connected to pin 162, interface body 12 moves closer to connector body 11, compressing pin 162 and spring 161, causing spring 161 to retract. When it can no longer move, spring telescopic rod 171 engages with pin 162, thus making interface body 12 more stable and preventing rotation. This avoids the interface body 12 from rotating during use, preventing scratches on the surface of the finished ferrule. The inclined design of moving block 172 allows it to move more quickly from the groove of pin 162 when the interface body 12 is inserted or removed, facilitating better replacement or cleaning of the finished ferrule. Due to the material limitations of the connector body 11 and interface body 12, stainless steel is free of harmful substances and has good chemical stability, reducing the risk of contamination from harmful substances caused by metal corrosion. Its smooth and hard surface makes it easy to clean and prevents stains from easily adhering to the surface. It also possesses high mechanical strength and durability, extending its service life. The guide groove on the interface body 12 near the spring 161 ensures that when the interface body 12 and the finished ferrule are installed, the pin 162 is aligned with the guide groove. This prevents the end face of the finished ferrule from rubbing and colliding with the connector body 11 as the interface body 12 moves the finished ferrule into the inner cavity of the connector body 11. This avoids scratches on the surface of the finished ferrule, preventing a decrease in coupling efficiency between the optical fiber and the ferrule, additional signal loss during transmission, increased insertion loss, and impact on the overall system transmission performance.

[0027] like Figure 1 , Figure 7 As shown, the movable part 33 has limit blocks on both sides, the bottom base plate 31 has a limit groove at the lower end, the bottom base plate 31 has an isolation groove at the upper end, the limit ring 35 is made of rubber, and the upper end of the limit ring 35 has a slot. The limit ring 35 is movably connected to the optical fiber body 2.

[0028] The above solution employs the following: Through the cooperation of the bottom substrate 31 and the movable component 33, and the design of the limiting blocks on both sides of the movable component 33 and the limiting groove on the bottom substrate 31, when the movable component 33 is pulled to move the connecting rope 34 and the limiting ring 35, the limiting groove and the limiting blocks limit the movable component 33, making its movement more stable. The movable component 33 moves the connecting rope 34 and the limiting ring 35, allowing the limiting ring 35 to fix and limit the optical fiber body 2. Limiting the optical fiber body 2 effectively prevents the optical fiber from moving or deviating during use, thereby maintaining the stability of the optical path, reducing signal loss, and preventing micro-bending caused by external forces by fixing the optical fiber body 2. This improves the transmission efficiency of the optical fiber, reduces insertion loss, helps reduce faults caused by optical fiber movement, improves the long-term reliability of the system, and reduces maintenance costs. The design of the isolation groove at the upper end of the bottom substrate 31 further enhances this effect. The fiber optic isolation slot effectively prevents crosstalk between adjacent optical fibers, ensuring signal independence between channels, improving signal quality, and helping to keep the fiber in the optimal position, thereby improving the coupling efficiency between the fiber and the connector and reducing insertion loss. The isolation slot provides additional physical protection for the fiber, preventing damage caused by mechanical impact or pulling during use. The limiting ring 35 is made of rubber, which has good flexibility and can adapt to the slight movement and deformation of the fiber, ensuring that the fiber remains stable under different environmental conditions. The elasticity of the rubber allows it to effectively clamp fibers of different diameters, increasing design flexibility. The rubber has good shock absorption properties, effectively absorbing external vibrations and impacts, protecting the fiber and other optical components from damage. The slot design at the upper end of the limiting ring 35 allows for better fixation of the fiber body 2.
