Problems solved by technology

[0003] The optical cable pigtail is the key component to realize the sealing of the connection between the submarine optical cable repeater and the submarine cable. After the integrated production of the submarine optical cable repeater is completed, it needs to be transported long-distance, transferred to the ship and installed; during the laying construction process of the submarine optical cable repeater Among them, due to the design of the cardan shaft coupler and the optical fiber pigtail of the submarine optical cable repeater, the submarine optical cable repeater can play a certain buffer role in dealing with complex submarine landforms, transportation curves and avoiding damage to the photoelectric unit. At the same time, Due to the application environment of the submarine optical cabl

Example Embodiment

[0037] Example 1

[0038] See figure 2 As shown, the embodiment of the present invention provides a molding device for eccentric spiral fiber optic cable pigtails, which includes a second mold 2 for bending the middle of the spiral section of the fiber optic cable pigtails. The second mold 2 includes a rotating mold core 21 and a sleeve. The rotating nut 22 is arranged on the rotating mold core 21. The rotating mold core 21 is cylindrical. One end of the rotating mold core 21 is provided with a first semicircular arc section 26. The first semicircular arc section 26 The side away from the rotating core 21 is provided with a first fixing structure 27 for fixing the fiber optic cable pigtails. The first fixing structure includes a first base and a detachable first pressing block 23. The base 28 is provided with a first groove arranged along the axial direction of the rotating core 21, the first groove and the first pressing block 23 cooperate to fix the fiber optic cable pigtail, ...

Example Embodiment

[0039] Example 2

[0040] The embodiment of the present invention provides a forming device for eccentric spiral fiber optic cable pigtails. The difference from Embodiment 1 is that the rotating nut 22 is provided with a second fixing seat 222 at one end close to the first fixing structure 27. The rotating nut 22 is fixed to the rotating shaft 24 through the second fixing seat 222, and the rotating shaft 24 can move on the second fixing seat 222 relative to the rotating mold core 21, and the set The second fixing base 222 can move the rotating shaft 24 provided thereon relative to the rotating core 21, which can facilitate the placement of the fiber optic cable pigtails in the second section, and avoid the problem of The second interval between 21 and the second pressing roller 25 is relatively small, and the surface of the fiber optic cable pigtail is damaged.

Example Embodiment

[0041] Example 3

[0042] The embodiment of the present invention also provides a method for forming a spiral optical cable pigtail using the forming device as described in embodiment 1, including the following steps:

[0043] S1: see figure 1 As shown, a first mold 1 for bending the front end of the spiral section of an optical fiber pigtail is provided. The first mold 1 includes a fixing plate 11, a clamp 12 provided on the fixing plate 11, and a first bending component 13, so The clamp 12 is provided with a straight channel matching the shape of the fiber optic cable pigtail, and the first bending assembly 13 includes a runner 132 assembled on the fixing plate 11 and detachably connected to the runner 132 and can be wound around. The rotating part 133 that rotates on the axis of the runner 132, and a first pressing wheel 134 is rotatably arranged on the rotating part 133. The first pressing wheel 134 and the runner 132 are formed to match the shape of the fiber optic cable pigta...

Abstract

The invention discloses a molding device used for an eccentric spiral optical cable tail fiber as well as a molding method and relates to the field of optical cable tail fiber molding. The molding device comprises a second die used for bending the middle part of a spiral section of an optical cable tail fiber, the second die comprises a rotary die core and a rotary nut sheathed on the rotary die core, a first semicircle section is arranged at one end of the rotary die core, a first fixed structure used for fixing the optical cable tail fiber is arranged at one side, far away from the rotary die core, of the first semicircle section, a thread section is arranged at the middle part of the rotary die core, the rotary nut is connected with the thread section by virtue of a screw thread, a second pinch roller is fixed at one end, close to the first fixed structure, of the rotary nut by virtue of a rotating shaft, and a second interval which can be passed by the optical cable tail fiber is formed between the second pinch roller and the rotary die core. The molding device disclosed by the invention completes a bending operation on the spiral section of the optical cable tail fiber by virtue of the second die and has the characteristics of simplicity in demolding and no damage to the optical cable tail fiber when a demolding operation is carried out.

Description

technical field [0001] The invention relates to the field of forming optical cable pigtails, in particular to a forming device and forming method for eccentric spiral optical cable pigtails. Background technique [0002] The shape of the submarine optical cable repeater is a long cylinder, and there is a splice box connected to the submarine optical cable at each end. Its length exceeds that of a professional construction ship. It is inconvenient to board the ship and lay construction. Therefore, in order to overcome the above problems, a cardan shaft connector and a fiber optic cable pigtail are designed. The design of the cardan shaft coupling can ensure that the pigtail of the optical cable will not be damaged during transportation and laying construction. [0003] The optical cable pigtail is the key component to realize the sealing of the connection between the submarine optical cable repeater and the submarine cable. After the integrated production of the submarine op...
