Description

[0001] The present invention relates to an optical cable having an anti-

The present invention relates to an optical cable having an anti-rodent function. More particularly, the present invention relates to an optical cable for a large-capacity processing line, in which the weight of the cable can be minimized while securing an optical function and ADSS (All-dielectric self-supporting) performance.

Recently, optical cables have been mainly used as communication cables, and many optical cables have been installed in the form of lines.

In the case of installing the optical cable in the form of the machined line, the cable is often damaged by a rodent such as a mouse or a squirrel. Rats such as mice or squirrels can not perform the functions of the front teeth when they are left untreated due to the nature of the front teeth continuing to grow. Because of the problem that the long front teeth penetrate the roof of the mouth, .

When the optical cable is used for processing, the squirrel or mouse is used for grinding the front side of the cable and the cable is damaged.

Conventionally, in order to provide an erasing function, a method of enclosing a steel tape or the like inside the outer surface of a cable is considered, and as disclosed in Japanese Patent Application Laid-Open No. 2004-292317, a cable is provided with silafloufen and microencapsulated And a method of incorporating a capsaicin-containing patch or the like.

However, when steel tape is used, there is a problem that the steel tape needs to be separately grounded and the weight is increased when applied to the machining line. When the power line is installed around the optical cable of the machining line shape, If the tape can not be used and the capsaicin component is contained in the outer jacket of the cable, the insecticidal component such as silafluophen or the deterioration of the capsaicin can not provide a continuous function during the use period of the cable over time .

In addition, there is a method of providing a nylon layer inside the outer skin instead of a steel tape in order to provide an eraser function, but it has been experimentally confirmed that the erasing performance is only about 80% .

FIG. 7 shows a cross-sectional view of an optical cable having a conventionally introduced optical function.

7 shows a representative view of the Chinese registered utility model 20402841. The Chinese registered utility model 20402841 is constructed of a plurality of arcuate FRP members 2 on the outside of the core 1 to provide an optical function with an optical function. A technique in which an embossing layer surrounds the core 1 has been introduced.

As shown in FIG. 7, each of the plurality of arched FRP members 2 is formed in a sharp rectangular shape with an edge bent in an arch shape or a circular arc shape, and a gap is not present between adjacent arched FRP members 2 Can be confirmed.

The arch layer composed of the arched FRP member 2 of this type is normally considered to be capable of protecting the core of the cable from the rodent. However, when the cable is twisted or bent, the arched FRP member A problem arises such that a part of the FRP member 2 is twisted or pushed up due to interference by the sharp edges of the adjacent arched FRP member 2 or the like. Further, since the arch layer is composed of a plurality of arcuate FRP members 2 having sharp edges, it is expected that returning to the home position will be difficult if the specific arched FRP member 2 leaves the arch layer.

In the case of constructing the arch layer for the archiving function by arranging the arched FRP member 2 without a space, it is necessary to apply the arched FRP member 2 having various curvatures according to the diameter of the cable. Therefore, The manufacturing cost may increase.

If the outer diameter of the core 1 does not match the radius of curvature of the inner side of the arched FRP member 2, the FRP member 2 may not contact the core and lifting between the FRP member and the core may occur.

These problems mean that the circularity of the cable is not maintained and that a certain portion of the core can not be protected by the protective layer, which results in a problem of degrading the erasing performance and the durability of the cable.

An object of the present invention is to provide an optical cable for a large-capacity working line that can minimize the weight of a cable while securing an anti-rodent function and ADSS (All-dielectric self-supporting) performance.

In general, the optical unit 100 may include a tight buffer system and a loose tube system in which no empty space is present, and the optical unit 100 of the optical cable according to the embodiment of the present invention may include one optical Since a plurality of optical fibers are accommodated in the unit 100, a loose tube method is applied.

The optical unit 100 of the optical cable shown in FIGS. 1 to 3 can accommodate six optical fibers 110 and a waterproof member 130 in the loose tube 150. The loose tube 150 may be made of polybutylene terephthalate or polypropylene. The waterproofing member 130 may be made of a thixotropic compound jelly, a waterproof yarn, a waterproof powder, .

1 and 2 is provided with two optical units 100 around the center tension line 200 and the optical cable shown in FIG. 3 is provided with the center tensile line 200 are provided with four optical units 100.

 In this case, the optical unit 100 is disposed around the center tension line 200, and at least one intervening member may be provided to maintain the overall shape of the cable.

The optical cables shown in Figs. 1 to 3 are provided with three or one interposer 300, respectively. The intervening member may have a diameter corresponding to that of the optical unit 100, and may be made of polyethylene or polypropylene.

The number of the intervening elements may be increased or decreased according to the required communication capacity, and the core may not be constituted as in the following embodiments.

In the embodiment shown in Figures 1-3, the center tension line 200 is in contact with two and four light units 100, respectively, and is in contact with three and one interposition. The optical unit 100 or the interposition of the embodiment shown in Figs. 1 to 3 includes a center tensile line 200 having a circular cross section and arranged so as to be in contact with two adjacent optical units 100 or intervening members, a light unit 100 And minimizing the empty space inside the core that can be constructed as an intervening structure minimizes the movement of components constituting the core.

In order for the core to be constructed so as to be in contact with the center tension line 200 and the optical unit 100 having the corresponding diameter disposed around the central tensile line 200 so that the core does not move about the center tensile line 200, It is important to determine the diameter of the center tensile line 200 appropriately.

In this case, when the optical unit 100 and the intervening member have diameters corresponding to each other, when the sum of the numbers of the optical unit 100 and the intervening members is 5 or less based on 6, The diameter of the center tension line 200 should be larger than the diameter of the optical unit 100 or the intervening member when the diameter of the central tensile wire 200 is smaller than the diameter of the optical unit 100 or intervening members and is 7 or more. Of course, the size of the center tension line 200 can be determined within a range that satisfies the contact condition with the center tension line 200 and the contact condition between the adjacent optical unit 100 or intervening members.

A waterproof yarn 400 may be provided in the core hollow space. The waterproof yarn 400 may be made of various materials provided that it has absorbency.

The binding tape 500 may be in the form of a binding member for keeping the core C as a whole circular and for evenly adjusting the mounting surface of the following member 600 which is not limited to a binding tape Do not. It is preferable that the binding tape is a waterproof tape having a waterproof function. Even if water penetrates the outer sheath by a rodent, waterproofing tape has an effect of blocking moisture when a waterproof tape is used.

On the other hand, the embodiment shown in FIG. 2 may further include an inner jacket in which the core surrounds the at least one optical unit inside the beam member. That is, the inner jacket 800a may be provided at the outermost portion of the core (C). When the inner jacket 800a is provided, there is an effect that the core C can be protected once more even if a problem such as damage to the brush 600 is caused. The inner jacket 800a may be made of the same material as the outer jacket 800b described later.

According to the embodiment of the present invention shown in FIGS. 1 to 3, a plurality of the urging members 600 may be disposed outside the binding tape 500 or the inner jacket 800a so as to surround the core. The biasing member 600 is provided to prevent damages by rodents.

Specifically, the plurality of the urging members 600 may be arranged so as to be spirally wrapped along the longitudinal direction of the core C, and the pitch may be about 300 mm to 1000 mm.

1 to 3, the urging member 600 may be made of fiber reinforced plastics (FRP) having a width w greater than the thickness t and flat. have.

A plurality of the urging members 600 having a flat shape in which the width W is larger than the thickness t can be horizontally juxtaposed spirally at the same pitch on the outer circumferential surface of the core. Here, the flat shape means a flat or flat shape in which the upper and lower surfaces are not bent or curved in a specific direction with respect to a cross section. However, the flat shape does not mean a complete flat surface or the like, and it can be seen as a flat shape if the upper surface and the lower surface have a flat shape without bending as a whole.

Since the manufacturing method is complicated and the curvature of each of the irradiation members is changed according to the diameter of the cable because the members constituting the irradiation layer are formed in an arcuate or arcuate shape, It is possible to reduce the cost of the entire cable since the cable 600 is easy to manufacture and requires no curvature change depending on the diameter of the cable.

In addition, in the conventional technology, a steel tape or the like is provided inside the outer jacket 800 for the purpose of the waving function. However, since the weight of the cable is increased, the ADSS (All-dielectric self-supporting cable.

Fiber-optic cable for ADSS (All-dielectric self-supporting cable) is a fiber-optic cable installed between electric poles for telecommunication and power lines and steel towers.

Experimentally, it has been experimentally found that, in order to secure a sufficient function of the optical waveguide member 600, the optical waveguide member 600 has a Mhos hardness of 5.0 or more, a flexural modulus of 4500 kgf / mm ² or more, strength is preferably made of a non-metallic material of 90 kgf / mm ² or more. When the material of the ejection member is made of a material satisfying the above conditions, it is possible to protect the inside of the core safely by preventing the damage by the teeth of the rodents that can approach the processing line.

The optical cable according to the present invention can provide a sufficient function of the above-described optical function and can be applied to the deflecting member 600 made of fiber reinforced plastic (FRP) as a material of the deflector 600 for implementing the ADSS cable. have.

A flexural modulus of 4500 kgf / mm ² or more, and a flexural strength of at least 500 m / min, when the fiber reinforced plastic (FRP) Could meet all the requirements of a non-metallic material of 90 kgf / mm ² or more.

It is preferable that the irradiation member 600 is installed without a gap to protect the inside of the irradiation member 600 and keep the cable as circular as possible. Therefore, the urging member 600 may be formed in a flat shape, that is, in the form of a flat and long strip, and may be installed side by side along the circumferential direction of the core of the cable.

Each of the optical units constituting the ADSS (All-dielectric self-supporting cable) optical cable for a line according to the present invention can accommodate, for example, 6, 12 or 24 optical fibers 110, A large-capacity optical cable can be constructed by providing a plurality of optical units.

In the embodiment shown in FIGS. 1 to 3, the diameter D1 of the entire cable is expected to be at least about 4.5 millimeters (mm) to a maximum of 30 millimeters (mm), and the inside of the optical cable having such a diameter (Mm) to 4.0 millimeters (mm) and a thickness of 0.5 millimeters (mm) to 2.0 millimeters (mm) in order to maintain a maximum circularity, Respectively.

When the thickness and the width of the irradiation member 600 are smaller, they can be easily damaged by the teeth of a rodent. When the thickness and the width are larger, the irradiation function can be strengthened. However, Will greatly increase.

The outer jacket 800 may be formed on the outer side of the outer layer of the vibration member 600 and the outer jacket 800 may be made of polyethylene or high density polyethylene (HDPE). The outer jacket 800 may have a thickness of about 1.2 millimeters (mm) to about 2.5 millimeters (mm).

It is possible to wrap the outer circumferential surface of the outer circumferential surface of the outer circumferential surface of the outer circumferential surface of the outer circumferential surface of the outer circumferential surface of the outer circumferential surface of the outer circumferential surface of the outer circumferential surface of the outer circumferential surface of the outer circumferential surface.

At least one rib cord 700 for separating the outer jacket 800 may be provided on the inside of the outer jacket 800 during the field work.

As described above, the optical fiber according to the present invention is formed of a fiber reinforced plastic in both the center tension line 200 and the blade member 600. Therefore, even if the weight of the optical fiber is reduced, Can be improved.

4 shows a cross-sectional view of another embodiment of an optical cable according to the present invention. The description with reference to FIGS. 1 to 3 will be omitted.

The embodiment shown in Figures 1 to 3 has two and four optical units 100 around the center tension line 200 and each optical unit 100 accommodates six optical fibers 110 , A total of 12 optical fibers and 24 optical fibers (110).

It is assumed that eight optical units 100 shown in FIG. 4 are provided and twelve optical fibers 110 are provided in each optical unit 100 to have 96 optical fibers 110, There is a difference in that only the optical unit 100 is disposed without the interposition of the interposing member.

As described above, when the number of the optical units 100 or the intervening members disposed around the center tensile line 200 is seven or more based on six, the diameter of the center tensile line 200 is not less than the diameter of the optical unit 100 Or the like, the center tension line 200 and the optical unit 100 or the like disposed around the center tensile line 200 can be closely contacted without any empty space.

4, since only eight optical units 100 are provided, the diameter of the center tensile line 200 may be larger than the diameter of the optical unit 100 so that the hollow space inside the core may be in close contact with each other .

4, unlike the center tension line 200 shown in FIGS. 1 to 3, the center tension line 200 of the embodiment shown in FIG. 4 is provided with a polyethylene coating layer 230 outside the fiber reinforced plastic 210 do.

Accordingly, when the sufficient thickness of the center tension line 200 can not be formed only by the fiber reinforced plastic 210, the coating layer 230 may be added so that the thickness of the center tension line 200 Can be adjusted.

In order to improve the bending characteristics, the brush 600 may be spirally wound around the core along the longitudinal direction of the core, and is intended to protect the inside of the cable from damages caused by the teeth of animals such as rodents. Even if the thickness is sufficiently secured and sufficient rigidity is provided, a gap between the urging members 600 disposed in the longitudinal direction of the core may be too wide, or one of the disposed urging members 600 may be pushed up and twisted If the circular holding of the cable is not possible due to a problem, it is not possible to achieve the original function of the arm 600 in order to protect the core.

Therefore, the optical cable according to the present invention needs to optimally control the distance between the oscillating members 600 disposed on the outer circumferential surface of the core.

As described above, the width w of the beam member 600 is determined in the range of 1.5 millimeters (mm) to 4.0 millimeters (mm), and the thickness is in the range of 0.5 millimeters (mm) to 2.0 millimeters (mm) And the number of the beam members 600 installed in the cross sectional direction should be determined according to the capacity of the cable, that is, the number of the optical units 100 or the number of the optical fibers 110 accommodated in one optical unit 100 do.

Here, the width w and the thickness t of the beam member 600 mean the maximum value when the width or the thickness of the one member is not constant. For example, in the case where the widthwise ends of the blade member 600 are formed in a round shape as in the embodiment of the present invention, the width of the blade member 600 at the center position of the thickness is the largest, (W) of the width W of the wing.

Fig. 5 shows a partial enlarged view of the optical cable shown in Fig. 4. Fig.

5, the waving member 600 may have a flat shape having a width w larger than the thickness t, and the width direction end may be formed in a curved shape as a whole. Therefore, the width of the urging member 600 becomes largest near the center of the thickness.

  That is, the upper and lower surfaces in the thickness direction of each of the irradiation members 600 may be flat and rounded at both ends in the width direction.

The method of constructing the both ends in the width direction of the brush member 600 is to round the brush member 600 by extruding the brush member 600 using a mold having a round shape at both ends in the width direction, A grinding process or a chamfering process so as to have a round shape can be used.

As such, the width of each of the beam members is the largest in the thickness direction central region, that is, the width of the beam member 600 is larger than the width of the beam member 600, Even if bending or twisting of the cable occurs, the sharp edges of the beam member 600 minimize the physical interference such as the adjacent beam members being caught or caught by each other due to their rounded shapes It is possible to minimize the displacement of the urging member.

In addition, since the gaps between the beams 600 arranged in the longitudinal direction of the core are too wide to sufficiently protect the inside of the core, or there is no gap between the disposed irradiation members 600, In order to solve the problem of the circular holding of the cable due to the deformation such as the swing and twist of any one of the members 600, Respectively.

Is the sum of the widths of the respective oscillating members (600). If the width of the beam member 600 is sufficiently small, it can be assumed that the length of the arc passing through the center in the thickness direction of the beam member 600 is approximately equal to the width of the beam member 600,

Can be seen as the sum of the spacing (g) between the widthwise ends of each of the oscillating members (600).

Here, the size of the intervals g of the ends of each of the beam members 600 may be uniform, and in the case where the cable is bent or twisted, the gap between the specific beams may become temporarily large.

Experimentally, the sum of the gaps (g) between the blades 600 should be less than 2.0 millimeters (mm) to protect the interior of the core sufficiently to prevent penetration of the rodent's teeth, etc., accessible to the optical cable And it is confirmed that the cable can be kept at the maximum circular shape without causing any problem such that any one of adjacent irradiation members 600 is pushed up and twisted when the distance is more than 0.1 millimeter (mm).

In addition, since the urging member 600 is flat and the gap between the urging members 600 is secured, the urging member 600 can be brought into contact with the core, thereby preventing lifting between the waterproofing member and the core, It is possible to secure the structural stability.

The value becomes zero, and if bending or twisting of the cable occurs, some of the beam members may be twisted or displaced. This means that all the oscillating members 600 should not be arranged so as to be in close contact with each other without a gap in the boundary region and the sum of the gaps g between the oscillating members 600 should be greater than zero.

The widths of all the urging members 600 need not be equal to each other. That is, in the optical cable including n number of the irradiation members, when the n-1 number of the urging members has a width of 3.0 mm and the width of the remaining space is 3.0 mm, the width of the last urging member is 3.0 mm mm), the sum of the gaps (g) between the blurring members 600 is 2? R -

The last deflecting member 600 may have a width of 2.5 millimeters (mm) smaller than 3.0 mm (mm), which is the width of the previously disposed n-1 deflecting members, since the cable may be twisted when the cable is bent. ), And the sum of the gaps (g) between the blind members 600 is 2 &lt;

The warpage of the beam member 600 can be eliminated.

가 0.5 밀리미터(mm)가 된다는 의미는 설치류 동물의 이빨로부터 코어를 보호할 정도로 방서부재가 촘촘하게 배치되되, 0.5 밀리미터(mm)의 여유가 n개의 방서부재 사이로 분배되어 케이블의 벤딩의 방향성과 무관하게 방서부재(600)의 비틀림 등을 방지 또는 최소화할 수 있음을 의미한다.In this case, the irradiation member 600 is divided into 2? R -

Is meant to be 0.5 millimeter (mm), in order to protect the core from the teeth of the rodents, a 0.5 millimeter (mm) margin is distributed between the n number of jaws, It is possible to prevent or minimize the twisting and the like of the urging member 600.
