Description

Technical Field

[0001] This utility model relates to the field of multi-core fiber fusion splicing fixture technology, specifically, to an adjustable multi-core fiber fusion splicing alignment fixture. Background Technology

[0002] Multi-core fiber optic fusion splicers are high-precision devices used to simultaneously splice multiple optical fibers (such as 4-core, 8-core, 12-core, etc.) and are widely used in the construction of fiber optic communication networks. Their core functions include automatic core alignment, discharge splicing, and loss assessment. Through precision motors and image processing technology, they achieve rapid alignment of multiple fiber cores, significantly improving construction efficiency. Compared to single-core fusion splicers, they can complete batch splicing of ribbon or discrete optical fibers in one operation, reducing repetitive operations. However, they require higher operating skills and more rigorous cleaning and maintenance. Typical models include the SMF (G.652), suitable for high-density cabling scenarios such as data centers and 5G base stations.

[0003] During the fusion splicing process, the splicing fixture uses precision mechanical structures (such as V-grooves, pressure plates, etc.) to fix the optical fiber, ensuring that its end face is accurately aligned with the electrode rod and the V-groove, thus avoiding displacement that could affect the fusion quality. However, since multi-core fusion splicing typically involves flat busbars, such as 4-core, 8-core, or 12-core busbars, current fixtures can generally only clamp and position a single type of busbar. The slot size is fixed, making it difficult to achieve compatibility and resulting in poor flexibility in use. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide an adjustable multi-core fiber optic fusion splicing alignment fixture, so as to solve the problem that current fixtures can generally only clamp and position a single type of cable strip.

[0005] To solve the above problems, the present invention adopts the following technical solution;

[0006] An adjustable multi-core fiber optic fusion splice alignment fixture includes a fiber optic fusion splice control unit, two four-way drive seats, two electrode rods, and two clamping assemblies. The two four-way drive seats are horizontally symmetrically mounted on the fiber optic fusion splice control unit, and the two electrode rods are vertically symmetrically mounted on the fiber optic fusion splice control unit, forming a cross structure with the two four-way drive seats. The two clamping assemblies are respectively mounted on the two four-way drive seats. Each clamping assembly includes a base block, a cover, and a replacement block. The bottom of the base block is mounted on the four-way drive seat, and the cover is hinged to the base block. The base block has a mounting groove for engaging the replacement block. Multiple replacement blocks are prefabricated, and different replacement blocks have different core count slots.

[0007] As a further description of the above technical solution: a flexible pad is fixedly installed on the cover, and the flexible pad is aligned and engaged with the wire groove.

[0008] As a further description of the above technical solution: two magnetically engaging first magnetic blocks are respectively provided on the contact side of the bottom block and the clamping cover.

[0009] As a further description of the above technical solution: the top of the replacement block is provided with a handle groove, and the bottom of the replacement block is provided with a matching arc surface that mates with the mounting groove, the arc surface being located below the handle groove.

[0010] As a further description of the above technical solution: the bottom of the replacement block and the horizontal contact surface of the mounting groove are respectively provided with second magnetic blocks that attract each other.

[0011] As a further description of the above technical solution: the bottom of the replacement block is provided with two arc-shaped protrusions, and the bottom of the mounting groove is provided with an arc-shaped groove that engages with the arc-shaped protrusions.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] This solution uses multiple replacement blocks with different specifications of cable tray slots to work with the installation slots, allowing for flexible adjustment and switching of installation slots of different specifications to accommodate different core counts. This enables the device to perform fusion splicing of fiber optic cable trays with different core counts using replacement parts, and allows for flexible adjustment of replacement parts according to different core counts, making operation flexible and convenient.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0021] Please see Figures 1-4 In this utility model, an adjustable multi-core fiber optic fusion splice alignment fixture includes a fiber optic fusion splice control host 1, two four-way drive seats 2, two electrode rods 3, and two fixture assemblies 4. The two four-way drive seats 2 are horizontally symmetrically mounted on the fiber optic fusion splice control host 1, and the two electrode rods 3 are vertically symmetrically mounted on the fiber optic fusion splice control host 1, forming a cross structure with the two four-way drive seats 2. The two fixture assemblies 4 are respectively mounted on the two four-way drive seats 2. The fixture assembly 4 includes a base block 41, a cover 42, and a replacement block 43. The bottom of the base block 41 is mounted on the four-way drive seat 2, and the cover 42 is hinged to the base block 41. The base block 41 has an installation groove 44 for engaging the replacement block 43. Multiple replacement blocks 43 are prefabricated, and different replacement blocks 43 have different core count slots 45.

[0022] In this invention, the fiber optic fusion splicing control host 1 is first opened, and two pre-cut optical fibers to be spliced ​​are fixed onto two clamp assemblies 4. The clamp cover 42 is opened, and the corresponding replacement block 43 is selected according to the number of multi-core fiber optic cables. The replacement block 43 is inserted into the mounting groove 44, completing the clamp assembly. Then, the multi-core fiber optic cable is inserted straight into the cable slot 45 of the replacement block 43. The clamp cover 42 is then closed to press and position the multi-core fiber optic cable, ensuring its stability. Finally, the fiber optic fusion splicing control host 1 starts controlling the two four-way drive seats 2 to perform micro-splicing. The device adjusts and, in conjunction with the internal imaging mechanism, performs real-time detection to ensure that each optical fiber is fully aligned. It drives two four-way drive seats 2 to move relative to each other, so that the ends of the optical fibers are aligned and in contact. Then, it controls two electrode rods 3 to discharge and fuse the optical fiber joints. This enables the device to fuse optical fiber busbars with different core counts using replacement parts. The replacement parts can be flexibly adjusted according to different core counts, making the operation flexible and convenient. This solves the problems of existing fixtures, which can generally only clamp and position a single type of busbar, have fixed slot sizes, are difficult to be compatible, and have poor flexibility of use.

[0023] Please see Figure 1 Among them, a flexible pad 421 is fixedly installed on the cover 42, and the flexible pad 421 is aligned and cooperates with the wire groove 45.

[0024] In this invention, the flexible pad 421 is used to press the multi-core optical fiber cable inside the cable tray 45 with the cover 42, resulting in better stability.

[0025] Please see Figure 3 Two magnetically attached blocks 411 are respectively provided on the contact side of the bottom block 41 and the cover 42.

[0026] In this invention, the two cooperating first magnetic blocks 411 ensure good stability when the bottom block 41 and the cover 42 are closed, making it easy to open and close.

[0027] Please see Figure 3 and Figure 4 The replacement block 43 has a handle groove 431 at the top and an arc surface 5 at the bottom that matches the mounting groove 44. The arc surface 5 is located below the handle groove 431.

[0028] In this invention, the handle groove 431 facilitates the removal and replacement of the replacement block 43, making the replacement operation easier. Furthermore, the arc surface 5 makes the removal and placement of the replacement block 43 smoother and reduces operational resistance.

[0029] Please see Figure 2 Wherein: the bottom of the replacement block 43 and the horizontal contact surface of the mounting groove 44 are respectively provided with a second magnetic block 441 that attracts each other.

[0030] In this invention, the second magnetic block 441 makes the replacement block 43 more stable in its engagement with the mounting slot 44, and also makes it easier to remove, replace and adjust.

[0031] Please see Figure 2 The bottom of the replacement block 43 is provided with two arc-shaped protrusions 432, and the bottom of the mounting groove 44 is provided with an arc-shaped groove 442 that engages with the arc-shaped protrusions 432.

[0032] In this invention, the replacement block 43 is positioned by the arc-shaped groove 442 in conjunction with the arc-shaped protrusion 432, making installation convenient and precise.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
