Abstract

PURPOSE:To prevent a communication wire such as an optical fiber from mouse damage and to provide the wire with heat resisting and fire extinguishing functions by charging a gap between a communication wire and an outer shell body with balloons and sealing gas having chemical functions such as fire extinguishing, insecticide and raticide into the balloons. CONSTITUTION:The casing of the balloon 2 is made of ceramics or resin and the thickness is about 30mu, but the thickness can be reduced furthermore in accordance with a purpose. An assistant 21 made of a resin material to fix the balloons 2 is injected and the outer shell body 3 is made of a hard material and has flexible structure. The gap between the outer shell body 3 and the communication wire 1 such as the optical fiber is charged with the balloons 2 in which spacific gas is sealed to prevent the periphery of the communication wire 1 from friction with the outer shell body 3 and damage and to provide the wire 1 with vibration resistance, fire resistance, heat resistance, and corrosion resistance. For instance, the wire can be prevented from mouse damage by sealing gas hated by mica into the balloons 2 or the sealing of fire extinguishing gas can be utilized for fire extinguishing.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a coated outer shell of a communication line, which is composed of a core made of a communication line such as an optical fiber and a flexible outer shell. be. Among communication lines, communication lines such as optical fibers, in particular, must not cause damage to the outer periphery in terms of performance. In the field of invention, it is extremely important to prevent damage from external np1 to communication lines such as optical fibers. In particular, as in the invention of wood, it would be possible to cover optical fibers and other communication lines with flexible materials and shapes to provide flexible performance while providing robust optical fibers and other communication lines. The above field of use is an indispensable field in the optical industry (prior technology).According to the conventional technology, communication lines such as optical fibers are mainly coated with resin material, and the present invention In order to provide flexible performance as in the conventional method, a communication line such as an optical fiber is pressed into a flexible tube. However, in this conventional method, since the connection between the optical fiber communication line and the covering protector is not smooth, the optical fiber communication line partially sticks to the covering protector, which causes the optical fiber communication line to stick to the covering protector. There is a risk that communication lines such as optical fibers may break due to force being applied to the lines. In addition, where vibrations are transmitted to communication lines such as optical fibers, a friction phenomenon occurs between the outside of the communication lines such as optical fibers and the inside of conventional flexible tubes, causing minute damage to the outside of the communication lines such as optical fibers. often occurs. Furthermore, with conventional flexible tubes, there is a limit to the length that can be inserted into the tube. The limit is about 10 meters or less; if the length is longer than that, the belt-shaped outer shell should be wrapped in a spiral to form the shape, rather than being inserted into the tube. Furthermore, the conventional coating is made of a resin material. As a result, they are often damaged by rats and the like.

Conventional technology does not yet have a method to solve these problems (problems to be solved by the present invention).As mentioned above, conventional products include those in which communication lines such as optical fibers are simply inserted into flexible tubes, If the cable is simply wrapped in a spiral, there is a risk that the optical fiber or other communication line will be damaged by vibration and the outside of the optical fiber or other communication line will be scratched and damaged by friction.

The present invention provides for communication lines such as optical fibers without impairing the flexible performance of the outer shell, which serves as a covering protector.
The problem to be solved is to prevent damage to the outside of the communication line, such as an optical fiber, even if there is considerable vibration.

Furthermore, as mentioned above, the outside of the communication line, such as an optical fiber,
It is intended to prevent damage caused by being chewed by rats, etc., and to also provide properties such as fire resistance and extinguishing properties.

(Means for solving the problems, operations, embodiments, and effects) By providing a structure that allows communication lines such as optical fibers to have flexible performance while avoiding friction with the outer shell, This will give you an effect that is not available in other countries.

The details will be explained below with reference to the drawings. FIG. 1 is an external appearance diagram showing a partial view of one part of an embodiment according to the present invention. 1 is a communication line such as an optical fiber, and 11
is the outer peripheral surface portion of one communication line. 2 is in the shape of a balloon, into which special gases such as inert, fire extinguishing, insecticidal, rodenticidal, etc. can be optionally sealed. The outer skin of the balloon is made of ceramic, resin, or the like. The thickness of the outer skin is approximately 30 microns. However, depending on the application, it is possible to make the wall thickness even smaller. Reference numeral 21 is an auxiliary agent made of a resin material that fixes the balloon 2. 3 is an outer shell made of a hard material and has a flexible structure. The feature of the present invention is that a balloon encapsulated with a special gas (2) is filled in the gap between the outer shell (3) and the optical fiber communication line (1) to prevent friction with the outer shell (3). In addition, it is possible to provide vibration resistance, fire resistance, heat resistance, and corrosion resistance without damaging the outer periphery of communication lines such as optical fibers. These are all 2
This relates to the performance of the gas contained in the gas. For example, damage by rats can be prevented by enclosing gas that rats dislike.

Furthermore, by enclosing a fire-extinguishing gas or the like inside the balloon No. 2, it can also be used to extinguish fires.

Regarding the balloon structure, the strength of the outer skin can be further improved by attaching resin to the balloon.

Any gas can be encapsulated in a balloon using conventional balloon manufacturing equipment in a gas atmosphere for encapsulation. By mixing this with a solvent such as methanol, the strength of the balloon shell can be adjusted because the surface of the balloon itself is coated with these liquids. Therefore, the balloon to be selected can be determined based on the thickness of the balloon's skin that can withstand the external force applied to the balloon, the coating of the hardening agent, etc.

The amount of JBH gas contained therein can be determined depending on the application.

Since the balloon of the present invention can be manufactured in large quantities, it can be provided to the market at low cost. Therefore, it has marketability.
