Description

Technical Field

[0001] This utility model relates to the field of communication equipment, specifically a fiber optic cable junction box connector that is easy to maintain. Background Technology

[0002] An optical fiber junction box is a type of junction device that provides termination and patching for backbone and distribution layer optical fibers. After the optical fiber is introduced into the junction box, it is fixed, terminated, and distributed. Then, patch cords are used to connect the backbone and distribution layer optical fibers. The connector precisely aligns the cores of the two optical fibers, enabling efficient transmission of optical signals between the two fibers and minimizing signal loss.

After inspection, the connector is replaced or repaired, then put back into the fusion splicing module and tighten the screws. Because there are many connectors inside the fiber optic junction box, this disassembly and assembly greatly increases the workload of the staff and significantly reduces their work efficiency. Therefore, we provide a fiber optic junction box connector that is easy to inspect and repair to solve the above problems. Summary of the Invention

Each set of connecting sliders has two sliders. Each connecting slider has a limiting plate at both ends. One end of each limiting plate is fixedly connected to one side of a first trapezoidal slider. Each connecting slider has a trapezoidal groove at both ends. The first trapezoidal slider is slidably connected to the connecting slider through the trapezoidal groove. The top and bottom of the connector have extension grooves that match the first trapezoidal slider. The first trapezoidal slider is slidably connected to the connector through the extension groove. The top of the connector has a matching groove that matches the top of the limiting plate. The limiting plate is slidably connected to the connector through the matching groove. Each set of connecting sliders has a pressure plate at its top, and the bottom of the pressure plate is fixedly connected to the top of the first trapezoidal slider.

[0007] As a further embodiment of this utility model: the snap-fit ​​mechanism further includes a plurality of second limiting grooves formed on the outer wall of the connector, and an auxiliary slider is slidably connected to the inner side of each of the plurality of second limiting grooves, and an auxiliary spring is installed between the auxiliary slider and the second limiting groove.

[0008] As a further embodiment of this utility model: the adjustment unit includes a bidirectional lead screw and a third limiting slide rod that are rotatably connected to the top and bottom of the connector respectively via a rotating shaft. Two connecting sliders are slidably connected to the outer wall of the third limiting slide rod, and two connecting sliders are threadedly connected to the outer wall of the bidirectional lead screw.

[0011] As a further embodiment of this utility model: the adjustment mechanism further includes a ratchet fixedly connected to the outer wall of the rotating rod, a fixed shaft fixedly connected to one side of the connector, a rotating seat rotatably connected to the outer wall of the fixed shaft, and a torsion spring installed between the rotating seat and the fixed shaft, and ratchet teeth meshing with the ratchet fixedly connected to the outer wall of the rotating seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting up a snap-fit ​​mechanism, when the operator needs to repair the connector, first locate the corresponding connector, then pinch the upper and lower pressure plates with two fingers. At this time, the pressure plates drive the first trapezoidal slider to move into the extension groove inside the connector. At the same time, the first trapezoidal slider drives the limiting plate to move, and the auxiliary slider causes the limiting plates at the top and bottom of the connector to move relative to each other, thereby separating the limiting plate from the welding wiring module and no longer limiting the connector. At this time, the operator can pull out the connector for repair. By pinching the upper and lower pressure plates to drive the relevant components to move, the limiting plate is separated from the welding wiring module, releasing the limitation on the connector. The operator can easily pull out the connector for repair without complicated tools or cumbersome disassembly steps, improving the convenience and efficiency of repair. After the repair is completed, the connector can be inserted into its original position to continue repairing other connectors. This operation method can quickly repair multiple connectors one by one.

[0014] 2. By setting up an adjustment unit, when the operator repeatedly disassembles and reassembles the connector, due to the wear and tear on the slot caused by the disassembly and installation, when the connector is reinstalled into the fusion splice module, the operator manually turns the rotating rod. This rotating rod drives the bidirectional lead screw to rotate, thereby driving the two connecting sliders on the outer wall to move relative to each other at the top of the connector. At the same time, the connecting sliders drive the limiting plate to slide on the first limiting slide rod. Then, the two limiting plates at the top of the connector drive the two limiting plates at the bottom of the connector to slide on the ratchet until the operator can no longer turn the ratchet. When the operator stops turning the rotating rod, the ratchet and ratchet engage under the action of the torsion spring, limiting the ratchet and the rotating rod. This ensures that the limiting plate fits snugly against the slot, preventing the connector from shaking and causing unstable fiber optic connection. By turning the rotating rod to drive the bidirectional lead screw to rotate, driving the limiting plate to move, the position of the limiting plate can be dynamically adjusted according to the actual wear of the slot, ensuring that the limiting plate fits snugly against the slot, thereby compensating for slot loss, ensuring stable connector installation, and maintaining the stability of the fiber optic connection.

[0023] Please see Figures 1-3 This embodiment provides a fiber optic junction box connector that is easy to maintain, including: a fusion splicing and wiring module 1, with multiple slots 2 on one side of the fusion splicing and wiring module 1, and a connector 3 disposed inside each of the multiple slots 2. A snap-fit ​​mechanism and an adjustment unit are respectively disposed on the outside of the connector 3. The snap-fit ​​mechanism includes: a limiting plate 4, with a first trapezoidal slider 11 disposed at one end of the limiting plate 4, and a pressure plate 14 fixedly connected to the top of the first trapezoidal slider 11. An auxiliary slider 10 is disposed between each set of limiting plates 4, and an auxiliary spring 6 is installed between the auxiliary slider 10 and the connector 3. The snap-fit ​​mechanism includes two sets of connecting sliders 12 fixedly connected to the top and bottom of the connector 3, with two connecting sliders in each set. Each of the two ends of the connector 12 is provided with a limiting plate 4. One end of each limiting plate 4 is fixedly connected to one side of a first trapezoidal slider 11. Each connecting slider 12 has a trapezoidal groove at both ends. The first trapezoidal slider 11 is slidably connected to the connecting slider 12 through the trapezoidal groove. The top and bottom of the connector 3 are respectively provided with extension grooves that match the first trapezoidal slider 11. The first trapezoidal slider 11 is slidably connected to the connector 3 through the extension groove. The top of the connector 3 is provided with a matching groove that matches the top of the limiting plate 4. The limiting plate 4 is slidably connected to the connector 3 through the matching groove. A pressure plate 14 is provided on the top of each set of connecting sliders 12, and the bottom of the pressure plate 14 is fixedly connected to the top of the first trapezoidal slider 11. The snap-fit ​​mechanism also includes multiple second limiting grooves 7 opened on the outer wall of the connector 3. An auxiliary slider 10 is slidably connected to the inner side of each of the multiple second limiting grooves 7. An auxiliary spring 6 is installed between the auxiliary slider 10 and the second limiting groove 7.

[0024] When the operator needs to inspect the connector, first locate the corresponding connector 3, then pinch the upper and lower pressure plates 14 with two fingers. At this time, the pressure plates 14 drive the first trapezoidal slider 11 to move into the extension groove inside the connector 3. Simultaneously, the first trapezoidal slider 11 drives the limiting plate 4 to move, and the auxiliary slider 10 causes the top and bottom limiting plates 4 of the connector 3 to move relative to each other, thereby separating the limiting plate 4 from the welding wiring module 1 and no longer limiting the connector 3. At this time, the operator can pull out the connector 3, then release the pressure plates 14. Under the action of the auxiliary spring 6, the limiting plate 4 returns to its original position. At this point, the staff can inspect connector 3. After the inspection is completed, connector 3 can be inserted back into its original position and the other connectors 3 can be inspected. By pinching the upper and lower pressure plates 14, the relevant components can be moved to separate the limiting plate 4 from the welding wiring module 1, thereby releasing the limitation on connector 3. The staff can easily pull out connector 3 for inspection without complicated tools or tedious disassembly steps, which improves the convenience and efficiency of inspection. After the inspection is completed, connector 3 can be inserted back into its original position and the other connectors 3 can be inspected. This operation method can quickly inspect multiple connectors 3 one by one.

[0025] Please see Figures 3-5 The adjustment unit includes a bidirectional lead screw 17 and a third limiting slide rod 15 rotatably connected to the top and bottom of the connector 3 via a rotating shaft. Two connecting sliders 12 are slidably connected to the outer wall of the third limiting slide rod 15. Two connecting sliders 12 are threadedly connected to the outer wall of the bidirectional lead screw 17. A rotating rod 9 is fixedly connected to one end of the bidirectional lead screw 17. The outer wall of the bidirectional lead screw 17 is provided with positive and negative threads, and both positive and negative threads are threadedly connected to one connecting slider 12. The adjustment mechanism also includes a first limiting slide rod 5 fixedly connected to both ends of each auxiliary slider 10. A groove is provided at the end of the limiting plate 4, and the limiting plate 4 connects to the first limiting slide rod 5 through the groove. The sliding connection includes a second limiting slide bar 8 fixedly connected to the top of each limiting plate 4 at the bottom of the connector 3, and an auxiliary groove matching the second limiting slide bar 8 opened at the bottom of each limiting plate 4 at the top of the connector 3. The second limiting slide bar 8 is slidably connected to the limiting plate 4 through the auxiliary groove. The adjustment mechanism also includes a ratchet 16 fixedly connected to the outer wall of the rotating rod 9. A fixed shaft 19 is fixedly connected to one side of the connector 3. A rotating seat 18 is rotatably connected to the outer wall of the fixed shaft 19. A torsion spring 20 is installed between the rotating seat 18 and the fixed shaft 19. A ratchet tooth 13 that meshes with the ratchet 16 is fixedly connected to the outer wall of the rotating seat 18.

[0026] When the staff repeatedly disassembles and reassembles connector 3, the disassembly and installation of connector 3 causes some wear and tear on slot 2. When connector 3 is reinstalled into the fusion splice module 1, the staff manually turns the rotating rod 9. At this time, the rotating rod 9 drives the bidirectional lead screw 17 to rotate, thereby driving the two connecting sliders 12 on the outer wall to move relative to each other at the top of connector 3. At the same time, the connecting sliders 12 drive the limiting plate 4 to slide on the first limiting slide rod 5. Then, the two limiting plates 4 at the top of connector 3 drive the two limiting plates 4 at the bottom of connector 3 to slide on the ratchet 13 until the staff can no longer turn the ratchet 16. When the staff stops turning the rotating rod 9, the ratchet 13 and ratchet 16 are engaged and limited by the torsion spring 20. At the same time, the rotating rod 9 is limited, so that the limiting plate 4 fits against slot 2, preventing connector 3 from shaking and causing unstable fiber optic connection. Repeated disassembly and reassembly of connector 3 will cause wear and tear on slot 2, reducing the fit accuracy between slot 2 and connector 3, resulting in loose connection. By turning the rotating rod 9 to drive the bidirectional lead screw 17 to rotate, the limiting plate 4 can be moved. The position of the limiting plate 4 can be dynamically adjusted according to the actual wear of the slot 2, so that the limiting plate 4 fits tightly with the slot 2, thereby compensating for the loss of the slot 2, ensuring that the connector 3 is installed securely, and maintaining the stability of the optical fiber connection.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
