Description

Technical Field

[0001] This utility model relates to the field of optical fiber technology, specifically a portable optical fiber stripping device. Background Technology

[0002] In fiber optic communication networks, fiber optic wiring, termination, and maintenance are essential steps. Before these operations, the outer coating and buffer layer of the fiber must be precisely stripped to expose the internal glass core. No scratches, micro-bends, or breaks should be made to the core during this process, otherwise signal attenuation or even link interruption will occur.

[0003] Currently, the most commonly used fiber optic stripping tools by on-site construction workers are manual wire strippers, especially three-section wire strippers. Although these tools are simple in structure and inexpensive, they have significant drawbacks: First, their stripping effect is highly dependent on the operator's feel and experience, and novices are very likely to damage the fiber optic cable due to improper force or unstable operation; second, their operation is cumbersome, requiring switching between different sized blades and applying pulling force, which can easily generate axial stress on the fragile fiber optic cable, posing a risk of tearing or breaking it.

[0004] In addition, some portable wire strippers exist on the market, which strip the fiber by rotating or pulling. While these represent an improvement, they do not fundamentally solve the problems of cumbersome operation, inaccurate stripping force control, and lateral or axial stress on the fiber. For construction workers seeking high efficiency and success rates in harsh or confined environments (such as high-altitude work shafts or the back of server racks), existing tools still struggle to perfectly balance portability, ease of operation, and reliability. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a portable optical fiber stripping device. The device secures and circumferentially cuts the optical fiber by fastening the top cover. The stripping is completed by pushing the push plate on the top cover, which drives the moving plate and the upper and lower cutting blades to move axially. This greatly simplifies the process and improves work efficiency. The axial movement of the optical fiber and the upper and lower cutting blades ensures stability during stripping, avoids scratching the optical fiber, and improves the yield rate.

The components are mutually corresponding; a limiting rod 12 is provided between the fixed plate 11 and the side wall of the groove 4 away from the fixed plate 11, and the limiting rod 12 is in the same direction as the groove 7. A limiting hole 30 is opened on the movable plate 5 at the position corresponding to the limiting rod 12, and the limiting rod 12 moves through the limiting hole 30. A compression spring 13 is sleeved on the limiting rod 12 between the movable plate 5 and the side wall of the groove 4; the sliding component includes a slider 6 and a sliding groove 29. The slider 6 is fixedly installed at both ends of the movable plate 5, and the sliding groove 29 is opened on the inner side of the groove 4 and the opening direction is the same as the direction of the groove 7. The slider 6 is slidably connected to the sliding groove 29; a baffle 14 is provided at the bottom of the groove 4, and the distance from the baffle 14 to the movable plate 5 is greater than the length of the limiting tube 16;The upper cover 2 and the base 1 are provided with corresponding magnets 24, which can attract each other through the magnets 24; a viewing window 19 is provided at the center of the upper cover 2; corresponding handles 23 are provided on the upper cover 2 and the base 1, which can be used to open the upper cover 2 and the base 1; a scale mark 17 is provided on the limiting tube 16.

[0019] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows: According to the instruction manual Figures 1-2 As can be seen, when this utility model is in operation, the operator lifts the top cover 2 and passes the optical fiber to be stripped through the axis of the lower cutting blade 9 and the limiting tube 16. At this time, the lower cutting blade 9 is in contact with the side wall of the fixing plate 11. Based on the position of the optical fiber in the limiting tube 16, the length to be stripped is determined. Here, a scale mark 17 can be set on the limiting tube 16 to facilitate the operator to judge the length more accurately. After the length is confirmed, the operator presses the optical fiber into the groove 7 of the fixing plate 11. Since the diameter of the groove 7 is smaller than the outer diameter of the optical fiber sheath but larger than the inner diameter of the optical fiber sheath, the optical fiber sheath can be pressed into the groove 7 of the fixing plate 11 of the base 1 without damaging the internal optical fiber line, thus achieving initial stability. Then, the operator flips the top cover 2 and places it on the base 1. At this time, the first insertion rod 25 is inserted into the first insertion hole 26 to ensure horizontal stability between the upper cover 2 and the base 1, and the second insertion rod 27 is inserted into the second insertion hole 28 to ensure horizontal stability between the moving plate 5 on the base 1 and the moving plate 5 on the upper cover 2. Here, the first insertion rod 25 and the second insertion rod 27 are inserted vertically and rotated, so their shapes match the shape of the rotation path. The shapes of the first insertion hole 26 and the second insertion hole 28 match the shapes of the first insertion rod 25 and the second insertion rod 27, which can be understood by those skilled in the art. The wire groove 7 of the upper cover 2 corresponds to the wire groove 7 of the base 1, pressing and fixing the parts of the optical fiber that do not need to be stripped. The upper cutting blade 10 and the lower cutting blade 9 correspond to each other to cut the outer sheath of the optical fiber. The cutting blade here is a ring cutting blade, which is existing technology, and the blade diameter matches the inner diameter of the outer sheath of the optical fiber, which can be understood by those skilled in the art. With the upper cover 2 and base 1 fully engaged, the operator pushes the push plate 22, which, via the sliding plate 21, moves the movable plate 5 on the base 1 and upper cover 2. This moves the fiber sheath cut by the upper and lower cutting blades 9 away from the fixed plate 11, causing the fiber to detach. During this movement, the limiting tube 16 limits the fiber, ensuring the stability of the fiber sheath movement and preventing damage to the fiber. After stripping, the upper cover 2 is opened, the upper and lower cutting blades 9 separate, and the operator can gently pull out the cut cable. This invention greatly simplifies the process, improves work efficiency, and ensures stability during stripping by controlling the axial movement of the fiber and the upper and lower cutting blades 9, preventing damage to the fiber and increasing the yield.

[0020] Furthermore, this utility model can be equipped with multiple sets of wire grooves 7 with different diameters, upper and lower cutting blades 9 with different blade diameters, and limiting tubes 16 with different inner diameters, thereby using optical fibers of different diameters, improving the applicability of the device, and at the same time, making it easy to carry and applicable to a wide range of occasions.

[0021] A limiting rod 12 is provided between the fixed plate 11 and the side wall of the groove 4 away from the fixed plate 11. The limiting rod 12 is in the same direction as the groove 7. A limiting hole 30 is opened on the movable plate 5 at the position corresponding to the limiting rod 12. The limiting rod 12 moves through the limiting hole 30. A compression spring 13 is sleeved on the limiting rod 12 between the movable plate 5 and the side wall of the groove 4. During operation, the limiting rod 12 can further improve the stability of the movement of the movable plate 5. The function of the compression spring 13 is to ensure that the movable plate 5 is in contact with the fixed plate 11 during installation, ensuring accurate installation.

[0022] The sliding component includes a slider 6 and a groove 29. The slider 6 is fixedly installed at both ends of the movable plate 5. The groove 29 is opened inside the groove 4 and the opening direction is the same as the direction of the groove 7. The slider 6 and the groove 29 are slidably connected. The structure is simple and easy to repair and maintain.

[0023] The bottom of the groove 4 is provided with a baffle 14. The distance between the baffle 14 and the moving plate 5 is greater than the length of the limiting tube 16. When the moving plate 5 moves and hits the baffle 14, it means that the cutting is completed, which makes it convenient for personnel to confirm the cutting status.

[0024] The upper cover 2 and the base 1 are equipped with corresponding magnets 24, which can attract each other through the magnets 24, thereby improving the stability between the upper cover 2 and the base 1.

[0025] The upper cover 2 has a viewing window 19 at its center, which allows personnel to observe the fiber optic cutting process.

[0026] The upper cover 2 and the base 1 are provided with corresponding handles 23, which can be used to open the upper cover 2 and the base 1.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
