Description

Technical Field

[0001] This utility model relates to the technical field of fiber optic cable splicing equipment, and in particular to a fiber optic cable splicing device. Background Technology

[0002] Fiber optic cables are the core carriers for long-distance, high-speed signal transmission in modern communication networks. During communication engineering construction, network maintenance, and fault repair, splicing devices are often used to connect two segments of the cable. The performance of these splicing devices directly determines the signal transmission stability, attenuation level, and lifespan of the connected cable. In practical applications, splicing devices must simultaneously meet three core requirements: stable support, precise alignment, and reliable fixation of the fiber optic cable. They must prevent splice deviations caused by cable misalignment during the splicing process and also prevent damage to the cable sheath and internal fiber core to ensure long-term safety and reliability.

[0003] Existing fiber optic cable splicing devices have significant shortcomings in cable locking and alignment, as well as component coordination. In the cable locking and alignment process, some devices employ single-sided clamping or asymmetrical fixing structures, which cannot achieve uniform force fixation of the cable. This easily leads to axial offset or radial loosening of the cable during splicing, directly affecting the alignment accuracy of the splice end. Some locking mechanisms use rigid contact components such as metal, which, when in direct contact with the cable sheath, can easily scratch the sheath due to improper clamping force control, damaging the cable's waterproof and corrosion-resistant protective layer, and may even compress and damage the internal fiber core. Furthermore, the alignment adjustment of most devices relies on manual operation, and the adjustment accuracy is greatly affected by the operator's experience, making it difficult to achieve micron-level precise alignment of the splice end. This easily leads to splice deviation and increases the risk of signal transmission attenuation. Therefore, this fiber optic cable splicing device is provided to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a fiber optic cable splicing device that provides precise fiber optic cable splicing and locking, and offers both protection and adjustment advantages, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fiber optic cable splicing device, comprising:

[0006] A splicing support mechanism, comprising a support platform, on the top of which are fixedly connected several sets of optical fiber cable support bases;

[0007] An optical fiber fusion splicing assembly is disposed above a support platform and is used to splice optical fibers and cables that have been placed and fixed.

[0008] An optical fiber cable locking mechanism is provided above the support platform. The optical fiber cable locking mechanism is used to fix and align the optical fibers that need to be spliced.

[0009] As a further embodiment of this utility model: the optical fiber cable locking mechanism includes an annular support frame, a rotating gear ring rotatably connected to the side of the annular support frame, an annular fixing frame fixedly connected to the side of the rotating gear ring, a drive motor fixedly connected to the side of the annular support frame away from the rotating gear ring, a drive gear rotatably connected to the side of the annular support frame close to the rotating gear ring, and four sets of transmission rotating arms rotatably connected to the side of the annular support frame close to the rotating gear ring. Soft rubber fixing wheels are fixedly connected to the inner side of each transmission rotating arm, and a sliding ring is sleeved on the outer side of each set of transmission rotating arms.

[0010] As a further improvement of this utility model, the rotating shaft of the drive motor passes through the annular support frame and is fixedly connected to the drive gear.

[0011] As a further improvement of this utility model: the external teeth of the drive gear and the rotating gear ring mesh.

[0012] As a further improvement of this utility model, each set of sliding rings is slidably connected to the outside of the transmission arm at the corresponding position.

[0013] As a further embodiment of this utility model: rotating columns are fixedly connected to both sides of the sliding ring, and limiting holes are opened on the inner sides of the rotating toothed ring and the annular fixing frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the optical fiber cable locking mechanism drives four sets of transmission arms to move synchronously through the meshing transmission of the drive motor, drive gear and rotating gear ring, so as to realize the symmetrical clamping of the optical cable by the soft rubber fixing wheel, which has strong fixing stability. The soft rubber fixing wheel directly contacts the optical cable, which can not only enhance the friction to prevent displacement, but also avoid damage to the outer sheath of the optical cable. At the same time, by controlling the rotation angle of the drive motor, the rotation amplitude of the rotating gear ring can be finely adjusted to achieve precise alignment of the optical cable splice end, which greatly reduces the risk of splice deviation.

The embodiments of this utility model will be described below based on its overall structure.

[0024] Reference Figures 1 to 4 In this embodiment of the present invention, a fiber optic cable splicing device includes:

[0025] The splicing support mechanism 1 includes a support platform 11, and several sets of optical fiber cable support seats 12 are fixedly connected above the support platform 11.

[0026] Fiber optic fusion splicing assembly 2 is disposed above the support platform 11 and is used to splice the placed and fixed optical fibers and cables together.

[0027] The optical fiber cable locking mechanism 3 is disposed above the support platform 11. The optical fiber cable locking mechanism 3 is used to fix and align the optical fibers that need to be spliced.

[0028] The above scheme employs the following: the support platform 11 provides basic support for the entire splicing device, enabling the splicing support mechanism 1, the fiber optic fusion splice assembly 2, and the fiber optic cable locking mechanism 3 to be stably installed on it; several sets of fiber optic cable support seats 12 can initially support the fiber optic cables to be spliced, preventing the fiber optic cables from sagging due to their own weight and affecting subsequent operations; the fiber optic fusion splice assembly 2 is ready at a set position above the support platform 11, and can be activated to complete the splicing of two fiber optic cables after the fiber optic cable is fixed and aligned by the fiber optic cable locking mechanism 3; the fiber optic cable locking mechanism 3 works in conjunction with the fiber optic cable support seats 12 above the support platform 11, first clamping and fixing the fiber optic cable to be spliced ​​to prevent displacement during the splicing process, and then adjusting its own structure to ensure precise alignment of the splice ends of the two fiber optic cables.

[0029] The optical fiber cable locking mechanism 3 includes an annular support frame 31. A rotating gear ring 32 is rotatably connected to the side of the annular support frame 31. An annular fixing frame 33 is fixedly connected to the side of the rotating gear ring 32. A drive motor 34 is fixedly connected to the side of the annular support frame 31 away from the rotating gear ring 32. A drive gear 35 is rotatably connected to the side of the annular support frame 31 close to the rotating gear ring 32. Four sets of transmission rotating arms 36 are rotatably connected to the side of the annular support frame 31 close to the rotating gear ring 32. Soft rubber fixing wheels are fixedly connected to the inner side of each transmission rotating arm 36. 37. Each set of transmission rotating arms 36 is fitted with a sliding ring 38 on its outer side. The rotating shaft of the drive motor 34 passes through the annular support frame 31 and is fixedly connected to the drive gear 35. The drive gear 35 meshes with the outer teeth of the rotating gear ring 32. Each set of sliding rings 38 is slidably connected to the outer side of the corresponding transmission rotating arm 36. Rotating columns are fixedly connected to both sides of the sliding ring 38. Limiting holes are opened on the inner sides of the rotating gear ring 32 and the annular fixed frame 33. The sliding ring 38 is rotatably connected between the rotating gear ring 32 and the annular fixed frame 33 through the rotating columns and the limiting holes.

[0030] The above scheme is adopted: the annular support frame 31 serves as the core support component of the optical fiber cable locking mechanism 3, providing an installation reference for the rotating gear ring 32, drive motor 34, drive gear 35, and four sets of transmission rotating arms 36, ensuring that the positions of each component are relatively fixed; the rotating gear ring 32 can rotate around the side of the annular support frame 31, and the annular fixing frame 33 fixed on its side rotates synchronously with the rotating gear ring 32. At the same time, the rotating gear ring 32 transmits power through the engagement of its external teeth with the drive gear 35; the drive motor 34 is fixed on the side of the annular support frame 31 away from the rotating gear ring 32. After starting, its rotating shaft drives the drive gear 35 to rotate around the side of the annular support frame 31 closer to the rotating gear ring 32; when the drive gear 35 rotates, through the meshing relationship with the external teeth of the rotating gear ring 32, it drives the rotating gear ring 32 to rotate around the annular support frame 31. The support frame 31 rotates along its axis; four sets of transmission rotating arms 36 can rotate around the side of the annular support frame 31 near the rotating gear ring 32. The soft rubber fixing wheel 37 on its inner side is used to directly contact the optical fiber cable. During fixing, it can avoid damage to the outer sheath of the optical fiber cable and enhance the friction. The sliding ring 38 can slide along the outer side of the transmission rotating arm 36. Its two rotating columns are embedded in the limiting holes of the rotating gear ring 32 and the annular fixing frame 33. When the rotating gear ring 32 drives the annular fixing frame 33 to rotate, the limiting hole pushes the sliding ring 38 to slide on the transmission rotating arm 36 through the rotating column, thereby driving the four sets of transmission rotating arms 36 to rotate synchronously. This causes the soft rubber fixing wheel 37 to move towards the center to clamp the optical fiber cable or to open and release the optical fiber cable outward. At the same time, by adjusting the rotation angle of the rotating gear ring 32, the alignment adjustment of the optical fiber cable splice end can be achieved.

[0031] The working principle of this utility model is as follows: First, the preliminary preparation and optical cable positioning are carried out before splicing. The two optical fibers to be spliced ​​are placed on the support platform 11 of the splicing support mechanism 1. Several sets of optical fiber support seats 12 fixedly connected on the support platform 11 are used to initially support the optical cables to prevent the optical cables from drooping due to their own weight and changing the relative position of the splicing ends. At the same time, the placement angle of the optical cables is adjusted so that the splicing ends of the two optical cables are facing the working area where the optical fiber fusion splicing assembly 2 and the optical fiber locking mechanism 3 are located, laying the foundation for subsequent locking and splicing operations.

[0032] Next, the fiber optic cable locking mechanism 3 is activated to secure and precisely align the fiber optic cable. First, the drive motor 34, fixed to the side of the annular support frame 31 away from the rotating gear ring 32, is activated. The rotating shaft of the drive motor 34 passes through the annular support frame 31 and drives the drive gear 35 fixed thereto to rotate (the drive gear 35 is rotatably connected to the side of the annular support frame 31 closest to the rotating gear ring 32). Because the drive gear 35 meshes with the external teeth of the rotating gear ring 32, the drive gear 35 will drive the rotating gear ring 32 to rotate around the axis of the annular support frame 31, while the annular fixing frame 33 fixed to the side of the rotating gear ring 32 will rotate synchronously. At this time, the sliding ring 38... The rotating pins on both sides are inserted into the limiting holes of the rotating gear ring 32 and the annular fixing frame 33. The rotating limiting holes will push the sliding ring 38 to slide along the outside of the transmission arm 36 (the sliding ring 38 is slidably connected to the outside of the transmission arm 36), thereby driving the four sets of transmission arms 36 that are rotatably connected to the annular support frame 31 to rotate synchronously, so that the soft rubber fixing wheel 37 fixed on the inside of the transmission arm 36 moves closer to the center, and finally clamps the two optical cables to be spliced; at the same time, the rotation amplitude of the rotating gear ring 32 can be adjusted by controlling the rotation angle of the drive motor 34 to further fine-tune the position of the optical cable, so as to achieve precise alignment of the splicing ends of the two optical cables and prevent displacement during subsequent fusion splicing;

[0033] After the optical cables are fixed and aligned, the optical fiber fusion splicing assembly 2 above the support platform 11 is activated. The optical fiber fusion splicing assembly 2 performs fusion splicing on the splice ends of the two optical cables in the preset working position. During the fusion process, the optical fiber cable support base 12 on the support platform 11 continuously provides stable support for the optical cables, and the soft rubber fixing wheel 37 of the optical fiber cable locking mechanism 3 keeps the optical cables in a clamped state. This double protection ensures that the optical cables do not shake during the fusion process and avoids affecting the fusion quality due to displacement. After the fusion operation is completed, the drive motor 34 is turned off and its reverse rotation is controlled, which drives the drive gear 35, the rotating gear ring 32 and the ring fixing frame 33 to move in the opposite direction. The sliding ring 38 moves in the opposite direction with the limiting hole and slides back to its original position along the transmission arm 36. The transmission arm 36 drives the soft rubber fixing wheel 37 to open outward, releasing the fused optical cables. This completes the entire optical fiber cable splicing operation.

[0034] 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
