Description

Technical Field

[0001] This invention relates to the field of optical fiber fixing technology, specifically to a fusion splice tray for fixing optical fiber thermal fusion tubes. Background Technology

[0002] In fiber optic communication engineering construction, fiber optic fusion splicing is a critical process for ensuring the continuity of optical links. Fiber optic fusion tubes and splice trays are used to house and fix the splice points, directly affecting the reliability of the connection and the stability of transmission. Currently, the splice trays widely used in the industry mostly employ fixed slots, simple clamping plates, or binding structures to fix the fusion tubes.

[0003] Existing fusion splice trays generally suffer from poor compatibility. The fixing slots are of a single size, only compatible with specific specifications of fusion tubes, lacking compatibility with fusion tubes of different diameters and lengths. This can easily lead to situations where the clamping is too loose, causing displacement, or too tight, damaging the sheath. During fiber optic installation, due to operations such as coiling, the fiber optic cable is frequently moved. If the fusion tube is fixed first, it is easily pulled during fiber movement, potentially causing damage. If the fusion tube is fixed last, it is generally located in the middle, making it difficult to secure. Pulling the fiber at this point can also affect the coiling arrangement. Furthermore, existing fusion splice trays lack fiber bending protection, making excessive bending prone to occur at the transition point between the fusion tube and the fiber, leading to micro-bending loss or even fiber breakage. They also present problems such as inconvenient module expansion in multi-core splicing scenarios, low assembly / disassembly efficiency, and difficult maintenance. Summary of the Invention

[0017] 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.

[0018] Please see Figures 1-10 The present invention provides a technical solution: a fusion splice tray for fixing optical fiber hot melt tubes, including a fusion splice tray body 1, a fusion splice tray cover 2 installed on the upper side of the fusion splice tray body 1, a first mounting plate 3 arranged in an array inside the fusion splice tray body 1, a movable block 4 movably mounted on the upper array of the first mounting plate 3, a flexible pad 5 movably mounted on the movable block 4, and a rubber inclined pressure block 6 fixedly mounted on the flexible pad 5; The fixing component 7 includes a pressure-bearing top block 706 and a limiting inclined pressure block 712. The pressure-bearing top block 706 is fixedly installed on the upper side of the flexible pad 5, and the limiting inclined pressure block 712 is fixedly installed on one side of the movable block 4. Adjustment component 8 includes an adjustment wedge 807, a second mounting base plate 810, a sliding bracket 815, and a hinge rod 816. An adjustment wedge 807 is provided between two sets of movable blocks 4 arranged opposite to each other. Two sets of second mounting base plates 810 are movably provided on the first mounting plate 3. All movable blocks 4 are provided on the second mounting base plates 810. A sliding bracket 815 is movably installed on the first mounting plate 3. Two sets of hinge rods 816 are provided on both sides of the sliding bracket 815. One end of the hinge rod 816 is rotatably mounted on the second mounting base plate 810. Based on a clamping and adjustment structure, this equipment uses rubber inclined pressure blocks 6 to achieve flexible clamping of optical fiber hot fusion tubes. With the help of adjustment components 8, it can complete multi-dimensional spacing adjustment. The closing action of the fusion splice tray cover 2 automatically triggers the clamping and fixing. The whole device has the functions of adapting to hot fusion tubes of different specifications, quick positioning, stable clamping and automatic locking. It achieves the effect of simple installation and operation, firm and reliable fixing and no damage to optical fibers. It effectively solves the problems of poor compatibility, weak fixing, cumbersome manual clamping and low construction efficiency of traditional fusion splice trays.

[0019] Furthermore, the fixing component 7 also includes a mounting groove 701, a deformation guide groove 702, a base block 703, a first guide plate 704, a second guide plate 705, a guide insert 707, and a guide slot 708. The movable block 4 has a mounting groove 701, and a flexible pad 5 is installed in the mounting groove 701. A deformation guide groove 702 is formed on the inner side of the flexible pad 5. The base block 703, the first guide plate 704, the second guide plate 705, and the pressure-bearing top block 706 are sequentially fixedly installed in the deformation guide groove 702 from bottom to top. The support block 703, the first guide plate 704, and the second guide plate 705 do not contact each other. The upper end of the pressure-bearing top block 706 is higher than the upper end of the movable block 4. The upper side of the movable block 4 is flush with the upper side of the welding tray body 1. The upper end of the pressure-bearing top block 706 abuts against the welding tray cover 2. The bottom support block 703 is fixedly installed in the mounting groove 701. Guide inserts 707 are fixedly installed on both sides of the pressure-bearing top block 706. Two sets of guide slots 708 are opened in the mounting groove 701. The guide inserts 707 are movably inserted into the guide slots 708.

[0020] During use, this structure can press down on the pressure-bearing block 706 after the fusion splice tray cover 2 is closed, thereby causing the flexible pad 5 to bulge and deform. Finally, the rubber inclined pressure block 6 squeezes the optical fiber hot melt tube to achieve reliable fixation. The function of this structure is to automatically complete the pressing and fixing by the cover closing action, without the need for additional manual tightening, making it more convenient and faster to use. The advantage is that the fixing action is completed simultaneously with the closing action, improving construction efficiency. At the same time, the guide block 707 and the guide slot 708 cooperate with each other to ensure that the flexible pad 5 can only move stably in the vertical direction without tilting. Under the action of the bottom support block 703, the first guide plate 704, the second guide plate 705 and the pressure-bearing block 706, the flexible pad 5 can expand stably and completely, increasing the stability of the equipment during use. Furthermore, the fixing component 7 also includes deformation grooves 709, flexible blocks 710, and deformation cavities 711. Two sets of movable blocks 4 are arranged back-to-back on the second mounting base plate 810. The rubber inclined pressure blocks 6 on the two sets of movable blocks 4 are inclined in opposite directions. The two sets of movable blocks 4 on the second mounting base plate 810 are symmetrical along the longitudinal centerline of the first mounting plate 3. Deformation grooves 709 are arrayed on the rubber inclined pressure blocks 6, and flexible blocks 710 are fixedly installed within the deformation grooves 709. Deformation cavities 711 are formed within the flexible blocks 710. The two sets of movable blocks 4 being back-to-back means that the rubber inclined pressure blocks 6 on the movable blocks 4 face opposite directions. In this structure, the movable block 4, which is set opposite to the rubber inclined pressure block 6, tilts in the opposite direction, which can significantly increase the axial tensile resistance of the hot melt tube and prevent loosening and displacement after fixing. The deformation groove 709 can adapt to the deformation space of the flexible pad 5 and improve the fitting degree of hot melt tubes with different shapes. The flexible block 710 and the deformation cavity 711 ensure that the rubber inclined pressure block 6 can deform normally, while making the deformation process more controllable and preventing excessive deformation or squeezing damage. Furthermore, the fixing component 7 also includes anti-slip teeth 713, the length of the limiting inclined pressure block 712 is greater than the length of the rubber inclined pressure block 6, the upper end of the limiting inclined pressure block 712 is an inclined surface, and the anti-slip teeth 713 are fixedly installed in an array on the side of the limiting inclined pressure block 712 facing the rubber inclined pressure block 6.

[0021] The limiting inclined pressure block 712 is made of rubber. In the initial stage of placing the optical fiber hot melt tube, the limiting inclined pressure block 712 is located on the outermost side of the movable block 4, forming a figure-eight shape to clamp the hot melt tube. The anti-slip teeth 713 on it can be engaged at the edge of the hot melt tube to achieve temporary fixation before the installation of the welding tray cover 2. This makes it convenient for construction personnel to adjust and correct the position of the hot melt tube. The advantage of this structure is that it is not easy to slip or shift during placement, which improves the efficiency of early assembly. The limiting inclined pressure block 712 itself does not move with the rubber inclined pressure block 6. Therefore, the limiting inclined pressure block 712 is used to temporarily squeeze and fix the hot melt tube. After the welding tray cover 2 is installed on the welding tray body 1, it becomes mainly fixed by the rubber inclined pressure block 6. Furthermore, the fixing component 7 also includes anti-bending guard plates 714. Anti-bending guard plates 714 are evenly and fixedly installed on the outer side of the limiting inclined pressure block 712, and the anti-bending guard plates 714 do not contact each other.

[0022] In the actual wiring and fixing process, the anti-bending guard plate 714 set on the outside of the limiting inclined pressure block 712 can effectively limit the bending angle of the limiting inclined pressure block 712, avoid damage to the optical fiber due to excessive bending, and at the same time play a regular guiding role in the optical fiber route, making the optical fiber layout more neat. This structure is directly attached to the limiting inclined pressure block 712, and takes into account the protection of optical fiber while completing the temporary fixing. Furthermore, the adjustment assembly 8 includes a central frame 801, a rack 802, a limiting groove 803, a limiting post 804, a mounting base 805, a gear 806, a mounting bracket 808, a sliding block 809, a guide rail groove 811, a first threaded sleeve 812, a first adjusting screw 813, and a spring telescopic rod 814. The central frame 801 is fixedly mounted at the center of the first mounting plate 3. The rack 802 is movably mounted within the central frame 801, and the rack 802 has a limiting groove 803. The limiting post 804 is fixedly mounted within the central frame 801 and movably inserted into the limiting groove 803. Mounting bases 805 are fixedly mounted in an array on the central frame 801. Gears 806 are rotatably mounted within the mounting bases 805. The gears 806 and the rack 802 have teeth on them. The gear 806 is meshed, and adjustable wedges 807 are fixedly installed on both sides. The adjustable wedges 807 are inserted between two sets of oppositely arranged movable blocks 4 and abut against the movable blocks 4. Mounting brackets 808 are arranged in an array on the first mounting plate 3. The adjustable wedges 807 are rotatably mounted on the mounting brackets 808. Sliding blocks 809 are fixedly installed on the lower side of the movable blocks 4. Guide rail grooves 811 are arranged in an array on the second mounting base plate 810. Sliding blocks 809 slide in the guide rail grooves 811. A first threaded sleeve 812 is fixedly installed at one end of the rack 802. A first adjusting screw 813 is rotatably installed in the center frame 801. The first threaded sleeve 812 is threaded onto the first adjusting screw 813. A spring telescopic rod 814 is fixedly installed between the two sets of oppositely arranged movable blocks 4.

[0023] The spring telescopic rod 814 consists of a sleeve, a movable rod, and a spring. The sleeve and the movable rod are fixed on two sets of movable blocks 4 respectively. The spring is sleeved on the movable rod and abuts against the inner side of the sleeve. When fixing hot melt pipes of different diameters, this equipment rotates the adjusting wedge 807 and uses its shape to guide the movable blocks 4 to separate and move closer, thereby completing the adjustment of the clamping distance. The spring telescopic rod 814 provides a reliable reset capability for the movable blocks 4. After the adjustment is released, it can automatically return to its original position. This structure can adapt to hot melt pipes of different diameters, improve the versatility of the device, and form a stable diameter adjustment function to meet the diverse usage needs of the construction site. Furthermore, the adjustment assembly 8 also includes a threaded seat 817, a second threaded sleeve 818, a second adjusting screw 819, a positioning slider 820, and a transverse groove 821. The sliding bracket 815 is slidably installed on both sides of the central frame 801. One end of the sliding bracket 815 is fixedly installed with a threaded seat 817. The second threaded sleeve 818 is fixedly installed inside the threaded seat 817. The second adjusting screw 819 is rotatably installed on the first mounting plate 3. The second threaded sleeve 818 is threadedly connected to the second adjusting screw 819. The second adjusting screw 819 is located on the upper side of the first adjusting screw 813. The positioning slider 820 is fixedly installed on the lower side of the second mounting base plate 810. The first mounting plate 3 has a transverse groove 821, and the positioning slider 820 is movably inserted into the transverse groove 821.

[0024] When adapting to hot melt tubes of different lengths, this structure can adjust the spacing of the second mounting base plate 810 to match the actual length of the hot melt tube. At the same time, it allows the limiting inclined pressure block 712 to accurately abut against the connection between the hot melt tube and the optical fiber, and the anti-slip tooth 713 to stably engage in the connection position, ensuring accurate positioning. The first adjusting screw 813 and the second adjusting screw 819 are centrally set, which facilitates unified operation by construction personnel and realizes dual-dimensional adjustment of length and diameter, greatly improving the adaptability range of the fusion splice plate and meeting the needs of various construction scenarios. Furthermore, a scale plate 9 is fixedly installed on a set of movable blocks 4 near the first mounting plate 3. A movable groove 10 is opened on one side of the first mounting plate 3. The scale plate 9 is movably inserted into the movable groove 10. A semi-cylindrical lens 11 is fixedly installed on the movable groove 10. A scale line 12 is provided on the semi-cylindrical lens 11. The length of the movable groove 10 is adapted to the length of the transverse sliding groove 821.

[0025] During batch construction and precise adjustment, the scale plate 9 and movable groove 10 of this structure can intuitively display the adjustment position of the movable block 4. With the help of the scale line 12 and the semi-cylindrical lens 11, accurate readings can be achieved. Construction personnel can make preset adjustments in advance according to the specifications of the hot melt pipe without repeated trial adjustments, which improves adjustment efficiency and consistency. The length of the movable groove 10 is compatible with the transverse slide 821 to ensure that the scale display range matches the adjustment stroke, making the adjustment process visual and standardized, and more suitable for engineering batch use. Furthermore, the first mounting plate 3 has an array of positioning slots 13, and the welding tray body 1 has an array of elastic wedge-shaped blocks 14 fixedly installed. The elastic wedge-shaped blocks 14 are engaged in the positioning slots 13, and the spacing of the elastic wedge-shaped blocks 14 is adapted to the length of the first mounting plate 3.

[0026] During on-site assembly and expansion, the first mounting plate 3 can be quickly disassembled and assembled by interlocking the elastic wedge-shaped card block 14 with the positioning slot 13. At the same time, multiple sets of parallel expansion installations can be realized to meet the fiber optic splicing requirements of different capacities. Disassembly can be completed simply by moving the elastic wedge-shaped card block 14 in opposite directions, making the operation simple and quick. Working principle: In operation, the hot melt tube is first adjusted by adjusting component 8, and then temporarily positioned and clamped by fixing component 7. The specific working process is as follows: The fiber optic hot-melt tube is placed between two sets of opposing movable blocks 4. The limiting inclined pressure blocks 712 are distributed in a figure-eight shape. The anti-slip teeth 713 on them are used to engage with the connection between the hot-melt tube and the fiber optic cable, which is temporarily fixed before installation and facilitates position adjustment. The anti-bending guard plate 714 on the outside of the limiting inclined pressure block 712 restricts the fiber optic cable from excessive bending, avoids damage to the fiber optic cable, and plays a guiding role.

[0027] The spacing is adjusted according to the specifications of the hot melt pipe: Rotating the first adjusting screw 813 causes the rack 802 to move via the threaded action between it and the first screw sleeve 812, causing the gear 806 to mesh with the rack 802, driving the adjusting wedge block 807 to rotate. This pushes the two movable blocks 4 on both sides to slide along the guide rail groove 811 on the second mounting base plate 810 via the bottom sliding block 809. At this time, the spacing between the two opposing sets of movable blocks 4 decreases, achieving clamping diameter adaptation. During reset, the first adjusting screw 813 is reversed, and under the action of the spring telescopic rod 814, the two opposing sets of movable blocks 4... The movable blocks 4 are relatively close, and the distance between the two sets of movable blocks 4 facing each other increases; rotating the second adjusting screw 819 drives the sliding bracket 815 to move through the thread action between it and the second screw sleeve 818, so that the hinge rod 816 gradually becomes horizontal, and the two sets of second mounting base plates 810 move away from each other. The second mounting base plate 810 slides along the transverse sliding groove 821 on the first mounting plate 3 through the positioning slider 820 to achieve clamping length adaptation, and the same applies to resetting; the scale plate 9 moves in the movable groove 10, and works with the scale line 12 and the semi-cylindrical lens 11 to achieve accurate position reading.

[0028] When the welding tray cover 2 is closed, the cover presses down on the pressure-bearing top block 706, pushing the flexible pad 5 downward within the mounting groove 701 of the movable block 4; the guide block 707 slides along the guide slot 708 to ensure that the flexible pad 5 does not shift; the bottom support block 703, the first guide plate 704, and the second guide plate 705 are subjected to force and deform in sequence, pushing the rubber inclined pressure block 6 to bulge under the limit of the deformation guide groove 702; the deformation groove 709 provides space for deformation, and the flexible block 710 cooperates with the deformation cavity 711 to make the rubber inclined pressure block 6 fit tightly against and squeeze the hot melt tube to complete the fixation; the two sets of rubber inclined pressure blocks 6 are inclined in opposite directions, effectively increasing the axial tensile resistance of the hot melt tube and improving the fixation reliability.

[0029] During installation and disassembly, the first mounting plate 3 engages with the positioning slot 13 on the fusion splice tray 1 via the elastic wedge-shaped locking block 14. During disassembly, the elastic wedge-shaped locking block 14 can be moved in opposite directions to achieve quick disassembly and multiple sets of extended installation. After opening the fusion splice tray cover 2, the flexible pad 5 returns to its original position through its own elasticity, so that the rubber inclined pressure block 6 no longer squeezes the heat fusion tube, and the fiber optic heat fusion tube can be removed.
