Description

Technical Field

[0001] This invention relates to the field of fiber optic adapter technology, and more specifically to a single-mode fiber optic adapter connection protection structure for an SLD depolarization light source. Background Technology

[0002] Fiber optic adapter connection protection structures have an important application background in optical communication technology. With the rapid development of information technology, fiber optic communication networks have been widely used in data centers, metropolitan area networks, and long-distance transmission systems. As a key component connecting different fiber optic lines, the performance and reliability of fiber optic adapters directly affect the signal transmission quality of the entire system. Traditional fiber optic adapters cannot provide protection and buffering against external forces at the connection point, nor can they provide overheat protection for the fiber optic adapter when it overheats. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this invention provides a single-mode fiber optic adapter connection protection structure for SLD depolarization light sources, which effectively solves the problems of existing technologies being unable to buffer external forces and provide overheat protection for fiber optic adapters.

[0004] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a single-mode fiber optic adapter connection protection structure for an SLD depolarization light source, including a fiber optic adapter and a protective tensile mechanism for overheat protection of the fiber optic adapter and buffering against external tensile forces. The tensile mechanism includes an overheat protection component and a tensile component. The tensile component includes an external interface fixedly installed on the surface of the fiber optic adapter, and extension blocks are fixedly connected to both sides of the external interface. The overheat protection component includes a pneumatic telescopic rod fixedly installed inside the external interface, and the output end of the pneumatic telescopic rod is attached to a limit block; The reset component is used to reset the connecting wire and external connector when the connecting wire is stretched.

[0005] Furthermore, the reset assembly includes a connecting rod that is slidably inserted into the extension block. One end of the connecting rod is fixedly connected to a receiving block, and the other side of the receiving block is fixedly installed with a hinge seat. A deflection block is rotatably connected inside the hinge seat, and a clamping block is fixedly connected to the surface of the deflection block.

[0006] Furthermore, a spring is fixedly installed on one side of the clamping block two, and the other end of the spring is fixedly connected to the receiving block.

[0007] Furthermore, an airbag is fixedly installed inside the external interface, and two sets of airbags are connected to the surface of the airbag, with the two sets of airbags located on the same vertical plane.

[0008] Furthermore, a driving block is fixedly connected to one end of the connecting rod, and the driving block and the second airbag are located on the same vertical plane.

[0009] Furthermore, a second spring is fixedly installed on the lower surface of the drive block, and the other end of the second spring is fixedly connected to the external interface.

[0010] Furthermore, the external interface has an external connector that slides inside, the external connector is engaged with the clamping block, and the external connector is electrically connected to a connecting wire inside.

[0011] Furthermore, a limiting rod is fixedly connected to the surface of the driving block, an adjusting rod is fixedly connected to one end of the limiting rod, and a clamping block is fixedly connected to the surface of the adjusting rod.

[0012] Furthermore, a magnetic block is fixedly connected inside the clamping block one.

[0013] Furthermore, the limiting block is fixedly connected to the external connector, and the limiting block is slidably inserted into the external interface.

[0014] Furthermore, the fiber optic adapter employs dual-source orthogonal polarization combining technology, with an output power ≥32mW, a bandwidth of ≥30nm, and a polarization extinction ratio ≤0.20dB.

[0015] Furthermore, the fiber optic adapter has a built-in isolator to protect the light source and supports RS232 remote precise modulation.

[0016] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. This invention involves inserting an external connector into the interior of an external interface. When the external connector is inserted, it compresses airbag one, causing gas to flow into airbag two, which inflates airbag two. This inflates airbag two, which then drives a limiting rod, clamping block one, and adjusting rod to move vertically through the drive block. This ensures that both clamping blocks one are in contact with the connecting cable, and magnetic blocks fixed inside the two clamping blocks one provide magnetic force for auxiliary fixation. Simultaneously, the two clamping blocks two engage with pre-drilled slots on the surface of the external connector. When an external force pulls on the connecting cable, the external connector and connecting cable move horizontally outward, causing the two receiving blocks and deflection blocks to deflect around the hinge seat, stretching spring one. When the external force ends, the elasticity of spring one returns the connecting cable and external connector to their original positions, thus absorbing and resisting tensile forces. This further improves the tensile strength of the fiber optic adapter connection, preventing disconnection of the external connector and external interface due to external forces and enhancing the stability of the fiber optic adapter during use.

[0017] 2. In the event of prolonged use of the fiber optic adapter and excessive heat buildup inside the external connector and interface, the gas inside the pneumatic telescopic rod expands due to the increased temperature. This causes the pneumatic telescopic rod to slide outward, moving the external connector and connecting cable horizontally outward. This, in turn, causes the two sets of receiving blocks and deflection blocks to deflect around the hinge seat, stretching the first spring and disconnecting the external connector and interface. When the internal temperature of the external interface drops, the elasticity of the first spring causes the connecting cable and external connector to return to their original positions, reconnecting the external connector and interface. This further improves the safety of the fiber optic adapter during use, provides overheat protection, and extends the lifespan of the fiber optic adapter. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] The present invention will be further described below with reference to embodiments.

[0023] Example 1 A single-mode fiber optic adapter connection protection structure for an SLD depolarization light source, reference Figure 1 It includes fiber optic adapter 1, and further includes: a protective tensile mechanism for overheat protection of fiber optic adapter 1 and buffering against external tensile forces, including tensile components, such as... Figure 2 , Figure 5 As shown, the tensile strength component includes an external interface 2 fixedly mounted on the surface of the fiber optic adapter 1. Extension blocks 8 are fixedly connected to both sides of the external interface 2. An airbag 10 is fixedly mounted inside the external interface 2. Two sets of airbags 18 are connected to the surface of the airbag 10, and the two sets of airbags 18 are located on the same vertical plane. A driving block 20 is fixedly connected to one end of the connecting rod 12. The driving block 20 and the airbags 18 are located on the same vertical plane. A spring 19 is fixedly mounted on the lower surface of the driving block 20. The other end of the spring 19 is fixedly connected to the external interface 2. A limiting rod 6 is fixedly connected to the surface of the driving block 20. An adjusting rod 4 is fixedly connected to one end of the limiting rod 6. A clamping block 5 is fixedly connected to the surface of the adjusting rod 4. The external connector 7 is then inserted. When the external connector 7 is inserted into the external interface 2, it compresses the first airbag 10, causing the gas inside the first airbag 10 to flow into the second airbag 18, thus inflating the second airbag 18. This causes the second airbag 18 to move vertically through the drive block 20, driving the limiting rod 6, clamping block 5, and adjusting rod 4. This ensures that both sets of clamping blocks 5 are in contact with the connecting line 3, and the magnetic blocks 21 fixedly installed inside the two sets of clamping blocks 5 provide magnetic force for auxiliary fixation. When the external connector 7 is pulled out, the gas inside the first airbag 10 can flow back, increasing the internal space of the first airbag 10 and the second airbag 18, thus reducing the internal air pressure. This allows the adjusting rod 4, clamping block 5, and limiting rod 6 to return to their original positions through the elastic force of the second spring 19.

[0024] To further enhance the security of the fiber optic adapter 1, an overheat protection component is provided to protect the fiber optic adapter 1, such as... Figure 3 , Figure 4As shown, the overheat protection component includes a pneumatic telescopic rod 9 fixedly installed inside the external interface 2. The output end of the pneumatic telescopic rod 9 is attached to a limiting block 11, which is fixedly connected to the external connector 7. The limiting block 11 is slidably inserted into the external interface 2. When the fiber optic adapter 1 is overheated, the heat accumulation inside the external connector 7 and the external interface 2 causes the temperature to be too high. The temperature causes the gas inside the pneumatic telescopic rod 9 to expand, which causes the pneumatic telescopic rod 9 to drive the limiting block 11 to slide outward. This causes the external connector 7 and the connecting line 3 to move outward horizontally, thereby causing the two sets of receiving blocks 13 and deflection blocks 15 to deflect around the hinge seat 16 as the center. This causes the spring 14 to stretch, thereby disconnecting the external connector 7 and the external interface 2, thus achieving overheat protection for the fiber optic adapter 1.

[0025] Example 2 To further enhance the stability of the fiber optic adapter 1, a reset component is provided to reset the connecting cable 3 and the external connector 7 when the connecting cable 3 is stretched, such as... Figure 1 , Figure 4 As shown, the reset assembly includes a connecting rod 12 that is slidably inserted into the extension block 8. One end of the connecting rod 12 is fixedly connected to a receiving block 13, and the other side of the receiving block 13 is fixedly installed with a hinge seat 16. The hinge seat 16 is rotatably connected to a deflection block 15, and the surface of the deflection block 15 is fixedly connected to a clamping block 17. One side of the clamping block 17 is fixedly installed with a spring 14, and the other end of the spring 14 is fixedly connected to the receiving block 13. After the external connector 7 is inserted into the external interface 2, the two sets of clamping blocks 17 are respectively snapped into the reserved slots opened on the surface of the external connector 7. When there is external force pulling or the fiber optic adapter 1 overheats, the external connector 7 and the connecting line 3 move outward horizontally, thereby causing the two sets of receiving blocks 13 and deflection blocks 15 to deflect around the hinge seat 16 as the center, so that the spring 14 is stretched. When the external force ends and the temperature drops, the elastic force of the spring 14 drives the connecting line 3 and the external connector 7 to return to their original positions, realizing the reconnection of the external connector 7 and the external interface 2.

[0026] It is worth noting that this 840nm high-power, low-polarization SLD light source employs dual-source orthogonal polarization combining technology, achieving an output power ≥32mW, a bandwidth exceeding 30nm, and a polarization extinction ratio ≤0.20dB. It features a built-in isolator to protect the light source, supports RS232 remote precise modulation, and outputs via single-mode polarization-maintaining fiber, exhibiting excellent spectral and power stability. The fiber optic adapter 1 uses a pair of 840nm polarization-maintaining SLD light sources, orthogonally configured and coupled to a single-mode fiber via a PBS. The addition of an isolator prevents backlight damage to the SLD. It is suitable for optical coherence tomography (OCT), fiber optic sensing, biomedical imaging, and precision optical measurement, featuring high power, wide spectral output, low polarization, and high long-term stability.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
