Description

Technical Field

[0001] The invention relates to the technical field of optical cables, and in particular to a water drop protection type anti-aging optical cable. Background Art

[0002] With the vigorous development of optical fiber communication, optical fiber has been widely used in various fields due to its excellent performance such as large transmission capacity, low attenuation, long transmission distance, small size, light weight and low cost. It is currently the most promising communication transmission medium.

[0003] Existing optical cables have relatively poor toughness and are easily damaged by sharp structures. In the natural environment, the outer wall of the optical cable is gradually affected by sunlight and ultraviolet rays and ages. After being damaged, the contamination of the optical fiber connector and the moisture of the pigtail are one of the main causes of optical cable communication failures. In a humid and highly dirty storage environment, the optical cable is more susceptible to corrosion. After the cable is flooded, it will age under the action of the electric field, and finally lead to cable breakdown. In cold weather, ice and snow accumulate on the optical cable, causing the optical cable to be pulled apart. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a water drop protection type anti-aging optical cable, which improves the toughness of the optical cable and reduces the possibility of it being damaged by sharp structures, while reducing wind resistance and improving the tensile strength of the optical cable.

[0005] The invention discloses a water drop protection type anti-aging optical cable, comprising a suspension wire, wherein the bottom of the suspension wire is connected with an outer sheath through a suspension neck, the outer sheath is in an inverted V shape, an electrical unit is arranged on the outer sheath, and an optical unit is arranged in the middle of the outer sheath.

[0006] As a preferred solution of the present invention, the suspension wire is in a teardrop shape.

[0007] As a preferred solution of the present invention, a reinforcement member is provided inside the suspension wire.

[0008] As a preferred solution of the present invention, the outer wall of the outer sheath is wavy.

[0009] As a preferred solution of the present invention, a C-shaped protrusion is arranged at the top end of the outer sheath, and a C-shaped groove matching with the C-shaped protrusion is arranged at the bottom end of the suspension wire.

[0010] As a preferred solution of the present invention, a plurality of positioning protrusions are arranged at intervals between the C-shaped protrusions, and a positioning groove corresponding to the positioning protrusions is arranged on the inner wall of the C-shaped groove.

[0011] As a preferred solution of the present invention, the outer sheath, the suspension wire and the surface of the suspension neck are all provided with an anti-aging layer.

[0012] As a preferred solution of the present invention, the anti-aging layer is made of polyethylene.

[0013] As a preferred solution of the present invention, there are two electrical units, which are respectively arranged at two ends of the outer sheath.

[0014] As a preferred solution of the present invention, the suspension wire is provided with a through hole, and the inner wall of the through hole is provided with a non-stick coating.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the teardrop-shaped suspension wire and the inverted V-shaped structure can effectively reduce the wind resistance of the optical cable, the inverted V-shaped structure can effectively guide rainwater or condensed water to flow downward, and avoid moisture accumulation on the surface of the optical cable, thereby reducing the possibility of moisture penetrating into the interior of the optical cable along the suspension wire 1, and enhancing the waterproof performance of the optical cable. In cold areas, the inverted V-shaped structure can reduce the accumulation of ice and snow on the optical cable, because snow and ice are easier to slide down the slope, which helps to reduce the additional weight of the optical cable due to snow or ice accumulation, and reduce the structural stress and potential fracture risk caused by gravity. Compared with traditional cylindrical optical cables, the inverted V-shaped design can reduce the windward area and reduce wind resistance, making the optical cable more stable in strong wind environments, reducing the swaying and wear of the optical cable by wind, and improving its safety in severe weather conditions. The built-in electrical unit 5 can provide power transmission or signal monitoring functions, so that the optical cable has composite communication capabilities and is suitable for occasions where optical and electrical signals need to be transmitted simultaneously.

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0022] Example

[0023] Reference Figure 1-Figure 2 This embodiment provides a water drop protection type anti-aging optical cable, comprising a suspension wire 1, wherein the bottom of the suspension wire 1 is connected to an outer sheath 6 through a suspension neck 3, the outer sheath 6 is in an inverted V shape, the outer sheath 6 is provided with an electrical unit 5, and the middle of the outer sheath 6 is provided with an optical unit 4;

[0024] In this embodiment, the inverted V-shaped structure can effectively reduce the wind resistance of the optical cable. The inverted V-shaped structure can effectively guide rainwater or condensation water to flow downward, avoid moisture accumulation on the surface of the optical cable, thereby reducing the possibility of moisture penetrating into the interior of the optical cable along the suspension line 1, and enhancing the waterproof performance of the optical cable. In cold areas, the inverted V-shaped structure can reduce the accumulation of ice and snow on the optical cable, because snow and ice are more likely to slide down the slope, which helps to reduce the additional weight of the optical cable due to snow or ice accumulation, and reduce the structural stress and potential fracture risks caused by gravity. Compared with traditional cylindrical optical cables, the inverted V-shaped design can reduce the windward area and reduce wind resistance, making the optical cable more stable in strong wind environments, reducing the swaying and wear of the optical cable by wind, and improving its safety in severe weather conditions. The built-in electrical unit 5 can provide power transmission or signal monitoring functions, so that the optical cable has composite communication capabilities and is suitable for occasions where optical and electrical signals need to be transmitted simultaneously.

[0025] As a preferred solution of the present invention, the suspension wire 1 is in the shape of a teardrop. The teardrop-shaped design can reduce wind resistance. When wind blows, the teardrop-shaped suspension wire 1 can more effectively disperse the wind force, reduce the lateral force of the wind on the optical cable, and improve the stability and safety of the optical cable in a strong wind environment. The teardrop-shaped suspension wire 1 design may also make birds feel that it is not suitable as a habitat, thereby indirectly reducing the corrosion and pollution of the optical cable by bird droppings.

[0026] As a preferred embodiment of the present invention, a reinforcement member 2 is provided in the suspension line 1. The reinforcement member 2 is usually made of high-strength metal or non-metallic material, such as steel wire, glass fiber or aramid fiber, etc., which can significantly improve the overall mechanical strength of the optical cable, making it not easily damaged when subjected to external forces (such as stretching, extrusion or bending). The reinforcement member 2 serves as the skeleton inside the optical cable, providing necessary support for the optical cable, ensuring that the optical cable maintains structural stability under various environmental conditions (such as temperature changes, wind influences), and avoiding degradation of optical fiber performance due to structural deformation. Due to the presence of the reinforcement member 2, the optical cable can withstand greater loads and more complex installation conditions, such as crossing rivers, valleys or being installed in high wind speed areas, which helps to extend the service life of the optical cable and reduce the frequency of maintenance and replacement.

[0027] As a preferred solution of the present invention, the outer wall of the outer sheath 6 is wavy, and the wavy structure can improve the rigidity of the outer sheath 6. Compared with the planar structure, the wavy design can better disperse the stress under the action of external force, especially when encountering a sharp object. When the sharp object encounters the crest, it is difficult to damage the outer sheath 6 due to the thicker outer sheath 6. When the sharp object encounters the trough, although the thickness here is smaller, when the sharp object moves toward the inside of the outer sheath 6, the adjacent parts of the trough move closer to the middle and contact the sharp object, reducing the power of the sharp object, thereby enhancing the ability of the optical cable to resist bending, extrusion and stretching.

[0028] As a preferred solution of the present invention, a C-shaped protrusion 7 is provided at the top end of the outer sheath 6, and a C-shaped groove cooperating with the C-shaped protrusion 7 is provided at the bottom end of the suspension line 1. The cooperation between the C-shaped protrusion 7 and the C-shaped groove can provide a firm mechanical lock to ensure that the connection between the outer sheath 6 and the suspension line 1 is tighter and more stable, and is not easy to loosen even under strong winds, vibrations or other external forces. The C-type connection method can increase the tensile strength between the suspension line 1 and the outer sheath 6. When the optical cable is subjected to tension, the structure of the C-shaped protrusion 7 and the groove can disperse and relieve the tension to prevent breakage at the connection.

[0029] As a preferred solution of the present invention, the C-shaped protrusion 7 is provided with a plurality of positioning protrusions 8 at intervals, and the inner wall of the C-shaped groove is provided with positioning grooves corresponding to the positioning protrusions 8. The positioning protrusions 8 extend into the positioning grooves to form a double locking mechanism. In addition to the locking of the C-shaped protrusion 7 and the C-shaped groove, the embedding of the positioning protrusions 8 further enhances the firmness of the connection and improves the tensile strength and torsional resistance.

[0030] As a preferred solution of the present invention, the outer sheath 6, the suspension wire 1 and the surface of the suspension neck 3 are all provided with an anti-aging layer, which can effectively resist environmental factors such as ultraviolet radiation, extreme temperature changes, chemical corrosion, etc., delay the aging process of the material, and thus significantly extend the service life of the optical cable.

[0031] As a preferred solution of the present invention, the anti-aging layer is made of polyethylene.

[0032] As a preferred solution of the present invention, there are two electrical units 5, which are respectively arranged at the two ends of the outer sheath 6. The configuration of the two electrical units 5 can provide redundant power supply capability. If one of the electrical units 5 fails, the other can still maintain power supply, thereby ensuring the continuity and reliability of the communication system.

[0033] As a preferred solution of the present invention, the suspension line 1 is provided with a through hole 9, the inner wall of the through hole 9 is provided with a non-stick coating, and the through hole 9 runs through the suspension line 1. The through hole 9 can disperse the wind blowing through the optical cable, reduce wind resistance, and make the optical cable more stable in a strong wind environment, reduce shaking and vibration caused by wind, thereby reducing the mechanical stress and potential damage risk of the optical cable. By providing a non-stick coating on the inner wall, impurities can be prevented from accumulating on the inner wall of the through hole 9.

[0034] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
