Description

[0002] An optical cable is manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a cladding sheath as a transmission medium and can be used alone or in groups. An optical cable mainly consists of optical fibers, a plastic protective sleeve and a plastic outer skin.

[0021] Compared with the prior art, the present invention provides an outdoor highly durable optical cable, which has the following beneficial effects:

[0022] 1. In the case of this outdoor highly durable optical cable, when the optical cable shakes in a harsh environment, the installation ring will drive the flexible optical rod to move, thereby driving the piston located inside the cylinder to move. When the piston moves, the cylinder can extract the gas located between the inner sleeve and the outer sleeve. As the gas decreases, on the one hand, it can enhance the connection effect between the semi-circular airbag component and the inner sleeve, ensure the sealing between the inner sleeve and the outer sleeve, and improve the protection effect. On the other hand, reducing the air can reduce the contact between the air and the inner sleeve and the outer sleeve, further improving the corrosion resistance effect, thereby enhancing the durability of the optical cable. And the extracted gas will be transported into the semi-circular airbag component, thereby causing the semi-circular airbag component to expand, further enhancing the sealing effect and stability between the outer sleeve and the inner sleeve. The excess gas will enter the annular airbag component, thereby causing the annular airbag component to expand, improving the sealing performance and stability between the annular airbag component and the protective sleeve.

[0023] 2. In the case of this outdoor highly durable optical cable, through the provided fastening grooves, multiple protective sleeves can be fixedly connected to each other, so that multiple optical fiber components are tightly and fixedly connected to each other, improving the connectivity between them. Minute movement or vibration between the optical fiber components may cause attenuation of the optical signal during transmission; by fixing multiple optical fiber components, such minute movement or vibration can be significantly reduced, thereby reducing signal attenuation and ensuring the stable transmission of the optical signal, thus improving stability and reliability and enhancing the durability.

[0024] 3. When installing the outer sleeve of this outdoor highly durable optical cable, the hollow rod is inserted into the cylinder, and at the same time, it will press the slide plate and the partition plate to move, making the circular hole on the partition plate correspond to the position of the delivery pipe, so that the gas in the delivery pipe can be transported into the cylinder through the circular hole, and then enter the hollow rod through the through hole on the slide plate, and then enter the annular airbag component, thereby causing the annular airbag component to expand, improving the sealing performance and stability between the annular airbag component and the protective sleeve, and enhancing the durability.

[0025] The parts not involved in this device are the same as or can be implemented using the prior art. In the present invention, it is possible to improve the durability of the optical cable in a harsh environment, improve the corrosion resistance, prevent the optical cable from being damaged, and ensure the use effect and service life of the optical cable.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0038] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0039] Example 1: Refer to Figures 1 - 10 , an outdoor highly durable optical cable, including a plurality of optical fiber assemblies 1, and further including a plurality of protective sleeves 101 respectively wrapped on the outer walls of the plurality of optical fiber assemblies 1; and an inner layer sleeve 2 wrapped on the outer walls of the plurality of optical fiber assemblies 1, and a plurality of annular airbag members 201 that abut against the protective sleeves 101 are provided on the inner wall of the inner layer sleeve 2; an outer layer sleeve 3 is also provided, and semi-circular airbag members 305 are provided at both ends of the inner wall of the outer layer sleeve 3, and the two semi-circular airbag members 305 are respectively wrapped on both ends of the inner layer sleeve 2; a cylinder body 5 is provided on the outer wall of the outer layer sleeve 3, and the cylinder body 5 is respectively communicated with the two semi-circular airbag members 305; an installation ring 4 is slidably provided on the outer wall of the inner layer sleeve 2, a flexible optical rod 403 is provided on the installation ring 4, and a piston 502 is provided on the flexible optical rod 403, and the piston 502 is slidably connected in the cylinder body 5.

[0040] In this embodiment, during use, first, the inner layer sleeve 2 is sleeved on the outer walls of the plurality of optical fiber assemblies 1, and then the two outer layer sleeves 3 are buckled and connected to the outer wall of the inner layer sleeve 2. After installation, the semi-circular airbag members 305 on the inner wall of the outer layer sleeve 3 abut against the outer wall of the inner layer sleeve 2. Then, the installation ring 4 is connected to a fixed building, so as to realize the positioning of the optical fiber assemblies 1. By providing the inner layer sleeve 2 and the outer layer sleeve 3, multi-layer protection can be provided for the optical fiber assemblies 1, thereby improving the high-temperature resistance and corrosion resistance effects of the optical fiber assemblies 1 during use and improving the durability.

[0041] During the use process, if there is the action of strong wind or external force, and since the mounting ring 4 is slidably connected to the inner sleeve 2, the optical fiber assembly 1 will shake or wobble. When shaking, the mounting ring 4 will drive the flexible optical rod 403 to move, thereby driving the piston 502 located in the cylinder 5 to move. When the piston 502 moves, the cylinder 5 can extract the gas located between the inner sleeve 2 and the outer sleeve 3. And through the two semi-circular airbag members 305, the inner sleeve 2 and the outer sleeve 3 can form a sealed cavity. As the gas inside the cavity decreases, on the one hand, it can enhance the connection effect between the semi-circular airbag member 305 and the inner sleeve 2, ensure the sealing performance between the inner sleeve 2 and the outer sleeve 3, and improve the protection effect. On the other hand, reducing air can reduce the contact between the air and the inner sleeve 2 and the outer sleeve 3, further improving the corrosion resistance effect, thereby enhancing the durability of the optical cable. And the extracted gas will be transported into the semi-circular airbag member 305, so that the semi-circular airbag member 305 expands, further enhancing the sealing effect and stability between the outer sleeve 3 and the inner sleeve 2. The excess gas will enter the annular airbag member 201, so that the annular airbag member 201 expands, improving the sealing performance and stability between the annular airbag member 201 and the protective sleeve 101, and improving the use effect.

[0042] During the actual use process, it is necessary to connect the inner sleeve 2 and the outer sleeve 3 to the optical cable passing through the harsh environment. An installation seat 313 is also provided at the tails of the inner sleeve 2 and the outer sleeve 3, which can connect multiple inner sleeves 2 and outer sleeves 3 to each other, improving the use effect. And during use, corrosion-resistant and high-temperature-resistant coatings are applied to the protective sleeve 101, the inner sleeve 2 and the outer sleeve 3, thereby further achieving the effects of high temperature resistance and corrosion resistance.

[0043] A fastening groove 102 is respectively provided on multiple protective sleeves 101, and the multiple protective sleeves 101 are fastened to each other through the fastening groove 102. By providing the fastening groove 102, the multiple protective sleeves 101 can be fixedly connected to each other, so that the multiple optical fiber assemblies 1 are tightly fixedly connected to each other, improving the connectivity between them. Minute movement or vibration between the optical fiber assemblies 1 may cause attenuation of the optical signal during transmission. By fixing the multiple optical fiber assemblies 1, this minute movement or vibration can be significantly reduced, thereby reducing signal attenuation, ensuring the stable transmission of the optical signal, and thus improving stability and reliability and enhancing the durability.

[0044] The outer side of the protective sleeve 101 is provided with a limiting groove 103, and the annular airbag member 201 is provided with a protruding portion 202. The protruding portion 202 of the annular airbag member 201 is inserted into the limiting groove 103. By providing the annular airbag member 201, a plurality of protective sleeves 101 can be fixedly connected. The protruding portion 202 of the annular airbag member 201 is inserted into the limiting groove 103, which can limit the plurality of protective sleeves 101 by the annular airbag member 201, making their connection tighter, further improving stability and durability, and preventing the optical fiber assembly 1 from being damaged in a harsh environment, etc.

[0045] Embodiment 2: Refer to Figures 1 - 10 , an outdoor highly durable optical cable, including a plurality of optical fiber assemblies 1, further including a plurality of protective sleeves 101 respectively wrapped on the outer walls of the plurality of optical fiber assemblies 1; and an inner layer sleeve 2 wrapped on the outer walls of the plurality of optical fiber assemblies 1. The inner wall of the inner layer sleeve 2 is provided with a plurality of annular airbag members 201 abutting against the protective sleeves 101; an outer layer sleeve 3 is also provided. Both ends of the inner wall of the outer layer sleeve 3 are provided with semi-circular airbag members 305, and the two semi-circular airbag members 305 are respectively wrapped on both ends of the inner layer sleeve 2; a cylinder 5 is arranged on the outer wall of the outer layer sleeve 3, and the cylinder 5 is respectively communicated with the two semi-circular airbag members 305; an installation ring 4 is slidably arranged on the outer wall of the inner layer sleeve 2. A flexible optical rod 403 is arranged on the installation ring 4, and a piston 502 is arranged on the flexible optical rod 403. The piston 502 is slidably connected in the cylinder 5.

[0046] There are two outer layer sleeves 3. Both of the two outer layer sleeves 3 are arranged in a semi-circular shape. After the two outer layer sleeves 3 are buckled, they are wrapped on the inner layer sleeve 2, and each outer layer sleeve 3 is provided with two semi-circular airbag members 305. The semi-circular airbag members 305 on the same side of the two outer layer sleeves 3 abut against each other.

[0047] A hollow rod 203 is arranged on the outer wall of the inner layer sleeve 2. The hollow rod 203 is communicated with the annular airbag member 201. A cylinder 306 is arranged on the inner wall of the outer layer sleeve 3. A sliding plate 307 is slidably connected in the cylinder 306. A through hole is arranged on the sliding plate 307, and a delivery pipe 309 is arranged between the semi-circular airbag member 305 and the cylinder 306.

[0048] A partition plate 311 is arranged on the sliding plate 307. The partition plate 311 is attached to the inner wall of the cylinder 306. A round hole 312 is arranged on the partition plate 311. When the round hole 312 moves to a position corresponding to the delivery pipe 309, the gas in the semi-circular airbag member 305 can enter the cylinder 306 through the delivery pipe 309. An elastic member 308 is arranged between the sliding plate 307 and the inner wall of the outer layer sleeve 3.

[0049] In this embodiment, refer to Figure 3 , Figure 8 , Figure 9 and Figure 10, when the optical cable shakes in a harsh environment, since the position of the mounting ring 4 is fixed, the piston 502 will be reciprocally pulled to slide in the cylinder 5 under the action of the flexible optical rod 403. When the piston 502 moves to the left in the cylinder 5, the gas between the inner sleeve 2 and the outer sleeve 3 will be extracted through the suction pipe 504 on its right side and enter the right side of the piston 502. And at this time, the gas on the left side of the piston 502 will be discharged through the air outlet pipe 503, so as to enter the semi-circular airbag part 305, thereby making the semi-circular airbag part 305 expand, further enhancing the sealing effect and stability between the outer sleeve 3 and the inner sleeve 2. When the semi-circular airbag part 305 expands to the point where it can no longer expand, the excess gas will enter the delivery pipe 309 and then enter the cylinder 306 again. Before that, when installing the outer sleeve 3, the position of the cylinder 306 is made to correspond to that of the hollow rod 203, and then the hollow rod 203 is inserted into the cylinder 306, which will simultaneously press the slide plate 307 to move, thereby driving the partition plate 311 to move, making the circular hole 312 on the partition plate 311 correspond to the position of the delivery pipe 309, so that the gas in the delivery pipe 309 can be delivered into the cylinder 306 through the circular hole 312, then enter the hollow rod 203 through the through hole on the slide plate 307, and then enter the annular airbag part 201, thereby making the annular airbag part 201 expand, improving the sealing performance and stability between the annular airbag part 201 and the protective sleeve 101, and improving the use effect. If the gas inside both the semi-circular airbag part 305 and the annular airbag part 201 tends to be saturated, the excess gas can be discharged through the air release valve 310 on the outer sleeve 3 to avoid damage to the semi-circular airbag part 305 and the annular airbag part 201. And after the annular airbag part 201 expands, its protruding part 202 will also expand, thereby tightly abutting against the limiting groove 103 on the protective sleeve 101, improving the connection effect with the protective sleeve 101, and at the same time enabling better fixing between multiple protective sleeves 101, so that multiple optical fiber components 1 are fixed to each other, improving durability.

[0050] When the piston 502 moves to the right in the cylinder 5, the suction pipe 504 on its left side extracts the gas between the inner sleeve 2 and the outer sleeve 3 and makes it enter the left side of the piston 502, and other operations are the same as above.

[0051] In the initial state, the partition plate 311 abuts against the delivery pipe 309, which can prevent the gas from flowing out of the delivery pipe 309 and avoid gas leakage. The elastic member 308 provided can make the slide plate 307 automatically reset after moving, facilitating repeated use. The elastic member 308 can specifically adopt a spring or a spring piece, etc.

[0052] There are two groups of air outlet pipes 503 and air extraction pipes 504 provided on the cylinder body 5. The two groups of air outlet pipes 503 and air extraction pipes 504 are respectively placed at both ends of the piston 502. The air outlet pipe 503 connects the cylinder body 5 and the semi-circular airbag member 305. The air extraction pipe 504 is placed between the outer sleeve 3 and the inner sleeve 2. The two groups of air outlet pipes 503 and air extraction pipes 504 provided can respectively perform air collection operations on the two semi-circular airbag members 305, which is convenient for use.

[0053] One-way valves are provided on both the air outlet pipe 503 and the air extraction pipe 504. A deflation valve 310 is provided on the outer sleeve 3. The deflation valve 310 is connected to the semi-circular airbag member 305. A limiting cylinder 501 is also provided on the outer wall of the cylinder body 5. The flexible optical rod 403 is slidably connected in the limiting cylinder 501.

[0054] Specifically, one-way valves are provided on both the air outlet pipe 503 and the air extraction pipe 504. When the gas in the cylinder body 5 needs to be discharged, it will only be discharged through the air outlet pipe 503. At this time, through the one-way valve on the air extraction pipe 504, the gas can be prevented from being discharged through the air extraction pipe 504. When gas needs to be extracted, only the air extraction operation will be carried out through the air extraction pipe 504. At this time, through the one-way valve on the air outlet pipe 503, the gas can be prevented from being extracted through the air outlet pipe 503, improving the overall use effect.

[0055] The flexible optical rod 403 is set to a smooth structure. It is slidably connected to the limiting cylinder 501, and a sealing gasket is provided at the limiting cylinder 501, which can improve the sealing performance between the flexible optical rod 403 and the limiting cylinder 501 and prevent the gas in the cylinder body 5 from leaking. Secondly, the flexible optical rod 403 is set to be flexible, which can produce a certain bending effect and has a small elastic force, and can produce a certain compensation effect when bending.
