Optical fiber cable radial buffer process

Abstract

The application provides a radial buffering treatment process for an optical fiber coil, which comprises the following steps: winding a coil; mounting a coil shell to the outer side of the coil; and filling a buffering body between the coil and the coil shell. The application solves the problem of improving the anti-vibration and impact performance of the optical fiber coil. In the method, an elastic colloid is injected between the coil shell and the coil, and an elastic buffering body is formed after solidification, so that the assembly difficulty of the coil is reduced without special mounting structure. Through the radial buffering structure, the local stress of the coil during vibration and impact is reduced, and the stress state is obviously improved compared with the stress state without the buffering structure.

Description

Technical Field

[0001] The invention belongs to the technical field of underwater optical fiber microcable wired communication, and in particular relates to a radial buffering processing process for an optical fiber coil. Background Art

[0002] To achieve real-time transmission of large amounts of information, such as underwater high-definition video, underwater vehicles typically rely on optical fiber to transmit data to surface platforms. Long lengths of optical fiber are typically stored in spools and mounted on the vehicle, from which the fiber is pulled out during movement. With the significant increase in underwater vehicle speeds and the growing demand for launches from surface and aerial platforms such as drones and ships, spools must be able to withstand the intense vibration and impact conditions associated with high-speed navigation and submersion. As a complex assembly formed by axially densely wound layers and coated with glue, the stability of optical fiber spools in harsh mechanical environments such as vibration and impact directly impacts the reliability of optical fiber communications. Therefore, improving the impact resistance of the spool is of great engineering significance. In addition to traditional vibration reduction methods using integral mounting structures, the vibration and impact resistance of the spool itself also needs to be improved to accommodate situations where external vibration reduction structures lack sufficient space or are insufficiently effective. Summary of the Invention

[0003] In order to solve the problems existing in the above-mentioned prior art, the present application proposes a radial buffering treatment process for an optical fiber coil, comprising the following steps:

[0004] Winding wire package;

[0005] Install the coil housing onto the outside of the coil package;

[0006] A buffer body is filled between the wire package and the coil shell.

[0007] Furthermore, filling a buffer body between the wire package and the wire ball shell specifically includes:

[0008] Place the axis of the wire package parallel to the ground;

[0009] Opening a glue injection hole on the cable package shell;

[0010] The buffer material is injected between the wire package and the coil shell under normal pressure through the injection hole.

[0011] Furthermore, the cross section of the glue injection hole is conical, and the diameter of the glue injection hole located on the inner side of the wire package shell is larger than the diameter of the glue injection hole located on the outer side of the wire package shell.

[0012] Furthermore, the cone angle of the cross section of the glue injection hole is 45°.

[0013] Furthermore, the diameter of the glue injection hole located on the inner side of the wire package shell is 10 mm.

[0014] Furthermore, the number of the glue injection holes in the axial direction of the wire package housing is 2, and the number of the glue injection holes in the circumferential direction of the wire package housing is 6 to 8.

[0015] Furthermore, after the coil shell is installed, the axial distance between the center of gravity axis of the glue injection hole and the end plate of the coil shell is greater than or equal to 15 mm.

[0016] Furthermore, the buffer material is silicone rubber, which forms the buffer body after natural solidification.

[0017] Furthermore, when injecting the buffer material, two injection holes that are 180 degrees opposite to each other are selected and injected simultaneously, and this step is repeated until a uniformly distributed buffer body is formed.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention solves the problem of improving the vibration and impact resistance of optical fiber coils. This method uses elastic colloid to be injected between the shell and the coil package, which forms an elastic buffer body after solidification. No special installation structure is required, which reduces the difficulty of coil assembly. By adding a radial buffer structure, the local stress of the coil during vibration and impact is reduced, and the stress state is significantly improved compared to the stress state without adding a buffer structure.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described below.

[0024] Combine Figure 1 and Figure 2 The present application proposes a radial buffering treatment process for an optical fiber coil. After the coil package 3 is wound, the coil shell 1 is installed on the outside of the coil package, and an annular cavity is formed between the coil shell and the coil.

[0025] Place the wire bundle axis parallel to the ground and create glue injection holes in the wire bundle housing. Through these holes, inject silicone rubber under normal pressure between the wire bundle 3 and the wire bundle housing 1. After natural solidification, form a buffer 4. When injecting the silicone rubber, select two injection holes 180° apart and inject simultaneously. This method is repeated until all injection holes are filled with silicone rubber, forming a uniformly distributed buffer, thus completing the installation of the wire bundle's radial buffer structure.

[0026] The cross-section of the glue injection holes is conical, with the smaller diameter end on the outer surface of the coil housing and the larger diameter end on the inner surface. The taper angle is 45°, and the smaller diameter is typically 10mm. Two glue injection holes are located axially. After the coil housing is installed, the axial distance between the center of gravity of the glue injection holes and the inner end surface of the free end plate 2 or the fixed end plate 5 must be no less than 15mm. Six to eight groups of glue injection holes are evenly distributed around the circumference.

[0027] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. All equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification are within the scope covered by the patent of the present invention.
