Description

Technical Field

[0001] This utility model relates to the field of optical cable installation technology, specifically a pluggable optical cable connector fixing device. Background Technology

[0002] In modern communication networks, pluggable optical cable connector fixing devices are key components for enabling rapid connection and disconnection of optical cables. They are widely used in scenarios such as data centers, base stations, and outdoor communication links. Their core requirement is to ensure the precise connection of optical cable cores to maintain stable optical signal transmission while ensuring ease of operation. Existing devices mostly achieve positioning through shell clips and simple guide structures. Although they can meet basic plugging and unplugging requirements, there is room for optimization in terms of accuracy and stability design.

[0003] During the insertion and removal process, the optical cable in the current plug-in optical cable connector fixing device is prone to radial or axial movement of the connector due to manual operation deviation or insufficient precision of the guide structure. This can lead to misalignment of the fiber cores, causing optical signal attenuation or even interruption. Moreover, when the optical cable is subjected to unexpected tensile force, the locking strength of the existing snap-fit ​​fixing structure is limited, and the connector is prone to loosening. Especially in scenarios with dense cabling or external interference, such problems can frequently cause communication link interruptions, increasing maintenance costs and communication failure risks.

This utility model has a novel structure. By setting a limiting plate, an L-shaped locking block with a pressing bevel, and a fixing mechanism driven by a tension spring, the limiting plate ensures precise alignment during insertion, the L-shaped locking block automatically locks, and the locking block can be separated by pressing the pressure rod when unlocking. This not only improves the docking accuracy but also enhances the resistance to external interference, ensures stable optical signal transmission, and reduces the risk of communication failure.

[0008] Furthermore, limit grooves are provided on both sides of the inner wall of the first mounting groove, and limit blocks are fixedly connected to both sides of the two slides, with the limit blocks slidingly engaged with the inner wall of the limit groove.

[0009] Furthermore, the anti-detachment mechanism includes a rotating shaft rotatably fitted to the inner wall of the second mounting groove. One end of the rotating shaft is fixedly connected to a turntable. Two arc-shaped clamping plates are provided on the outer side of the turntable.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please refer to Figures 1 to 7This utility model provides a technical solution: a pluggable optical cable connector fixing device, including an optical cable connector 1, a device body 2 on one side of the optical cable connector 1, a plug-in groove 3 on the side of the device body 2 near the plug-in end of the optical cable connector 1, a first mounting groove 4 on the upper side of the device body 2, a fixing mechanism 5 inside the first mounting groove 4, and a second mounting groove 6 on one side of the device body 2, an anti-detachment mechanism 7 inside the second mounting groove 6 that cooperates with the optical cable connector 1. Limiting plates 8 are fixedly connected to both sides of the optical cable connector 1, and the limiting plates 8 are used to limit the insertion depth of the optical cable connector 1. When the optical cable connector 1 is inserted into the plug-in groove 3 of the device body 2, the limiting plates 8 will contact the outer wall of the device body 2, limiting the further insertion of the optical cable connector 1, avoiding damage to the internal fiber core due to excessive insertion, and ensuring precise alignment between the optical cable connector 1 and the plug-in groove 3, laying the foundation for the subsequent locking of the fixing mechanism 5, ensuring the stability of subsequent optical signal transmission, and preventing the connection effect from being affected by the insertion position deviation.

[0025] In this embodiment, the fixing mechanism 5 includes two sliding blocks 51 that slide against the inner wall of the first mounting groove 4. A trapezoidal pressing block 52 that cooperates with the two sliding blocks 51 is provided between them. A pressure rod 53 is slidably fitted on the upper side of the main body 2. A tension spring 54 is sleeved on the outer side of the pressure rod 53. An L-shaped locking block 55 is fixedly connected to the lower side of each of the two sliding blocks 51. A T-shaped sliding groove 56 is opened on the opposite side of each of the two sliding blocks 51. A T-shaped slider 57 is fixedly connected to both sides of the trapezoidal pressing block 52. A slot 58 that cooperates with the L-shaped locking block 55 is opened on both sides of the optical cable connector 1. The lower end of the pressure rod 53 extends into the interior of the first mounting groove 4 and is fixedly connected to the upper side of the trapezoidal extrusion block 52. The T-shaped slider 57 is slidably fitted on the inner wall of the T-shaped slide groove 56. The two ends of the tension spring 54 are fixedly connected to the inner wall of the first mounting groove 4 and the upper side of the trapezoidal extrusion block 52, respectively. The two L-shaped locking blocks 55 are slidably fitted on both sides of the inner wall of the insertion groove 3, and the opposite ends of the two L-shaped locking blocks 55 are both extrusion slopes. Limiting grooves 9 are provided on both sides of the inner wall of the first mounting groove 4. Limiting blocks 10 are fixedly connected to both sides of the two slide blocks 51, and the limiting blocks 10 are slidably fitted on the inner wall of the limiting grooves 9. When the optical cable connector 1 is inserted into the insertion slot 3, its end will press against the inclined surface of the L-shaped locking block 55, pushing the two slide blocks 51 to move to both sides. The T-shaped slider 57 slides along the T-shaped slide groove 56, and the tension spring 54 is stretched. When the optical cable connector 1 is fully inserted, the L-shaped locking block 55 is locked into the slot 58 under the action of the reset force of the tension spring 54, realizing automatic locking. When unlocking, the pressing rod 53 overcomes the elastic force of the tension spring 54, causing the trapezoidal pressing block 52 to move down and press against the slide block 51. The two slide blocks 51 drive the L-shaped locking block 55 to move to both sides and disengage from the slot 58, completing the unlocking. When the slide block 51 moves, the limiting block 10 slides along the limiting groove 9 to prevent displacement. This structure not only ensures smooth guidance during insertion, but also improves the fixation reliability through mechanical locking. The unlocking operation is convenient and labor-saving, taking into account stability and maintainability.

[0026] In this embodiment, the anti-detachment mechanism 7 includes a rotating shaft 71 rotatably fitted into the inner wall of the second mounting groove 6. One end of the rotating shaft 71 is fixedly connected to a turntable 72. Two arc-shaped clamping plates 73 are provided on the outer side of the turntable 72. Multiple dovetail grooves 74 are opened on one side of the main body 2. Dovetail sliders 75 are slidably fitted into the inner walls of the multiple dovetail grooves 74. Two corresponding dovetail sliders 75 are fixedly connected to one side of the corresponding arc-shaped clamping plate 73. Two arc-shaped extrusion grooves 76 are opened on the side of the turntable 72 near the arc-shaped clamping plate 73. Guide rods 77 are fixedly connected to the side of the two arc-shaped clamping plates 73 near the turntable 72. A spring-loaded spring 78 is installed on one side of the inner wall of the second mounting groove 6. The turntable 72 rotatably fits into the inner wall of the second mounting groove 6, the guide rods 77 slidably fit into the inner wall of the arc-shaped extrusion grooves 76, and one end of the spring-loaded spring 78 is fixedly connected to one side of the rotating shaft 71. The connecting cable of the optical cable connector 1 is pressed into the two arc-shaped clamps 73. The turntable 72 rotates under the action of the spring 78. The arc-shaped extrusion groove 76 pushes the guide rod 77 to move, which drives the arc-shaped clamps 73 to slide along the dovetail slide groove 74 and the dovetail slider 75 towards the cable. Finally, the arc-shaped clamps 73 clamp the cable. This structure can offset the tension when the cable is pulled by external force, prevent the tension from being transmitted to the connection between the optical cable connector 1 and the plug slot 3, prevent the connector from loosening, and further improve the device's resistance to external interference.

[0027] When using the device, first perform the positioning of the optical cable connector 1. Align the optical cable connector 1 with the insertion slot 3 of the main body 2 and insert it. During the insertion process, the end of the optical cable connector 1 first contacts the pressing slope of the L-shaped locking block 55, pushing the two slide blocks 51 to move to both sides. The T-shaped slider 57 slides synchronously along the T-shaped slide groove 56, and the tension spring 54 is stretched until the limiting plates 8 on both sides of the optical cable connector 1 are in contact with the outer wall of the main body 2. At this time, the insertion depth of the optical cable connector 1 is limited and it is precisely aligned with the insertion slot 3. At the same time, under the action of the restoring force of the tension spring 54, the L-shaped locking block 55 automatically locks into the slots 58 on both sides of the optical cable connector 1, and the fixing mechanism 5 completes the locking, realizing the initial stable fixation of the optical cable connector 1.

[0028] Next, the anti-detachment mechanism 7 is activated to strengthen protection. The connecting cable of the optical cable connector 1 is pressed between the two arc-shaped clamps 73. The turntable 72 rotates under the elastic force of the spring 78. The arc-shaped extrusion groove 76 on its outer side pushes the guide rod 77 to move, which drives the arc-shaped clamp 73 to slide along the dovetail slide groove 74 and the dovetail slider 75 towards the cable. Finally, the arc-shaped clamp 73 clamps the cable, which counteracts the tension generated when the cable is pulled by external force, and prevents the tension from being transmitted to the connection between the optical cable connector 1 and the plug slot 3, thus preventing the connector from loosening.

[0029] When unlocking and disassembly are required, press the lever 53 to overcome the elastic force of the tension spring 54 and move the trapezoidal pressing block 52 downward. The trapezoidal pressing block 52 presses the two slide blocks 51 to move to both sides. The slide blocks 51 drive the L-shaped locking block 55 to disengage from the slot 58. At the same time, the limiting blocks 10 on both sides of the slide block 51 slide along the limiting groove 9 to prevent the slide block 51 from shifting. At this time, the optical cable connector 1 can be pulled out to complete the unlocking operation. The entire process takes into account the accuracy of docking, the stability of fixation and the convenience of disassembly.
