Description

Technical Field

[0001] The present invention relates to a window coating device, in particular to an optical fiber window coating device. Background Art

[0002] The "windowing" splicing method for communication optical cables is an emergency measure taken in the event of a cable breakage or other incident during cable installation. Windowing and coating are also required during the manufacturing process of fiber optic Bragg gratings. Traditionally, this involves manually cutting the desired window with a handheld circular cutter, severing the protective coating at both ends of the windowed area. The cutter is then used to cut open the area, revealing the cable core.

[0003] This windowing method relies on the skills and experience of the operator. It is difficult to ensure the consistency of the ring cutting and cutting force, which can easily damage the cable core and is extremely inconvenient to use. For example, the patent with authorization announcement number CN218824830U discloses an outdoor optical fiber cable windowing tool, which belongs to the field of wire stripping tools. The windowing tool includes a gripping portion, a cutter, an adjusting rod and a locking member: the gripping portion has a first end and a second end, the first end is located above the second end; the second end is provided with an arc-shaped clearance for placing the cable; the cutter moves closer to or away from the arc-shaped clearance and the first end; the adjusting rod longitudinally passes through the first end and is connected to the cutter; the locking member is provided on the first end for locking the adjusting rod to the first end. The windowing tool has a simple structure and is easy to use. It can effectively perform radial ring cutting and axial cutting on the cable, quickly complete the cable windowing work, and effectively control the insertion depth of the cutter through the adjusting rod and the locking member to ensure that the cutting and cutting depths are consistent, avoid damaging the cable, and is safe to use.

[0004] Although the above technology has many advantages, it still has disadvantages in use: the length of the window is relatively fixed, the adaptability is poor, and the selection of the window position is inconvenient and cannot be adjusted according to actual conditions. In view of this, the present invention designs an optical fiber window coating device. Summary of the Invention
