Description

Technical Field

[0001] This utility model relates to the field of optical fiber transmission cable technology, and more specifically, to an anti-bending high-definition television signal optical fiber transmission cable. Background Technology

[0002] Fiber optic cables for high-definition television (HDTV) signals are the core carrier for achieving long-distance, high-quality transmission of HDTV signals. They mainly consist of a cable core, cladding, and protective layer. Their transmission principle is based on total internal reflection. After the HDTV signal is converted into a light signal of a specific wavelength, it undergoes repeated total internal reflection within the cable core, thus propagating forward along the cable. Compared to traditional transmission media such as coaxial cables, fiber optic cables have extremely low signal attenuation rates, maintaining stable HDTV signals over distances of hundreds of kilometers or even longer. This effectively avoids signal distortion and interference during transmission, providing a fundamental guarantee for users to enjoy clear and detailed picture quality.

[0003] Fiber optic cables for high-definition television signal transmission also possess significant advantages such as high bandwidth and strong anti-interference capabilities. With the continuous development of high-definition television technology, the demand for transmission bandwidth for ultra-high-definition signals such as 4K and 8K is increasing daily. Fiber optic cables have a bandwidth potential far exceeding that of traditional transmission media, easily meeting the real-time transmission needs of high-volume high-definition signals. Furthermore, optical fibers themselves are non-conductive and unaffected by electromagnetic and radio frequency interference. This allows for stable transmission of high-definition television signals even in complex electromagnetic environments, such as near high-voltage lines or substations, ensuring the smoothness and stability of television program playback.

[0004] Existing fiber optic cables for high-definition television signal transmission have certain limitations in practical use, the most prominent being their need for improved bending resistance. The cable core, typically made of glass or plastic, is relatively fragile. When subjected to significant bending forces, the core is prone to breakage, deformation, or micro-cracks. This damage not only leads to a sharp increase in high-definition television signal attenuation, causing problems such as blurred image quality, stuttering, or even signal interruption, but also necessitates the replacement of the damaged cable, increasing maintenance and time costs and negatively impacting the stable transmission of high-definition television signals. Utility Model Content

[0005] The purpose of this invention is to address the problem that the core of optical cables is usually made of glass or plastic, which is relatively fragile. When the optical cable is subjected to a large bending force, the core is prone to breakage, deformation or micro-cracks.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A bend-resistant fiber optic cable for high-definition television signal transmission is proposed to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] A bend-resistant high-definition television signal fiber optic transmission cable includes a cable body, which includes an outer sleeve. Multiple cable cores are disposed inside the outer sleeve. An inner sleeve is disposed outside the cable cores. The inner sleeve is a nylon sleeve. A first bend-resistant strip is fixed inside the outer sleeve. The first bend-resistant strip is an elastic rubber strip. Multiple wire-passing grooves are opened inside the first bend-resistant strip. The cable cores and the inner sleeve are located inside the wire-passing grooves.

[0010] As a preferred technical solution of this application, a second anti-bending strip is fixed inside the wire trough, and the second anti-bending strip is an elastic rubber strip.

[0011] As a preferred technical solution of this application, a tensile sleeve is fixed to the outside of the outer ring, and the tensile sleeve is a glass fiber tape winding layer.

[0012] As a preferred technical solution of this application, a flame-retardant sleeve is fixed to the outside of the tensile sleeve, and the flame-retardant sleeve is a silicone rubber sleeve.

[0013] As a preferred technical solution of this application, a corrosion-resistant sleeve is fixed to the outside of the flame-retardant sleeve, and the corrosion-resistant sleeve is a fluororubber sleeve.

[0014] As a preferred technical solution of this application, the corrosion-resistant sleeve is fixed with a plurality of wear-resistant strips arranged in a circumferential array, and the wear-resistant strips are polytetrafluoroethylene plastic strips.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] The elastic rubber strip has good bending resistance, which makes the optical cable body have good bending resistance. The first anti-bending strip wraps around multiple cable cores and inner rings, thus wrapping the cable cores. When the optical cable body is subjected to bending force, it can effectively reduce the phenomenon of cable cores being bent and breaking. In addition, the second anti-bending strip can further improve the bending resistance of the optical cable body. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0024] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of this utility model can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] like Figure 1-3 As shown, this embodiment proposes a bend-resistant high-definition television signal fiber optic transmission cable, including a cable body 1. The cable body 1 includes an outer sleeve 13, inside which multiple cable cores 11 are disposed. An inner sleeve 12, made of nylon, is fitted around the cable cores 11. A first bend-resistant strip 2, made of elastic rubber, is fixed inside the outer sleeve 13. Multiple threading grooves 21 are formed inside the first bend-resistant strip 2, with the cable cores 11 and the inner sleeve 12 located inside the threading grooves 21. The elastic rubber strip has good bend resistance, giving the cable body 1 good bend resistance. The first bend-resistant strip 2 wraps around the multiple cable cores 11 and the inner sleeve 12, thus effectively reducing the possibility of breakage of the cable cores 11 when the cable body 1 is subjected to bending force.

[0027] A second anti-bending strip 22 is fixed inside the cable tray 21. The second anti-bending strip 22 is an elastic rubber strip. The second anti-bending strip 22, made of elastic rubber, can further improve the bending resistance of the optical cable body 1. When the optical cable body 1 is subjected to bending force, the first anti-bending strip 22 can play a certain buffering role, which can effectively reduce the damage to the optical cable body 1 when subjected to bending force.

[0028] The outer sleeve 13 is fixed with a tensile sleeve 3, which is a fiberglass tape winding layer. Fiberglass tape has the advantage of high tensile strength. The tensile sleeve 3, which is made of fiberglass tape, can effectively improve the tensile strength of the optical cable body 1. When the optical cable is stretched, the cable core 11 is not easily damaged.

[0029] The tensile sleeve 3 is externally fixed with a flame-retardant sleeve 4, which is made of silicone rubber. Silicone rubber has good high-temperature resistance, and the flame-retardant sleeve 4 made of silicone rubber gives the optical cable a good flame-retardant effect, thereby enabling the optical cable body 1 to be used in high-temperature environments and improving its application range.

[0030] A corrosion-resistant sleeve 5, made of fluororubber, is fixed to the outside of the flame-retardant sleeve 4. Fluororubber has good corrosion resistance, and the corrosion-resistant sleeve 5 made of fluororubber can improve the corrosion resistance of the optical cable body 1, thereby enabling the optical cable body 1 to better adapt to different environments and improve its service life.

[0031] The corrosion-resistant sleeve 5 is externally fixed with multiple wear-resistant strips 6 arranged in a circumferential array. The wear-resistant strips 6 are made of polytetrafluoroethylene (PTFE) plastic. The wear-resistant strips 6 made of PTFE plastic have a low coefficient of friction, thereby reducing wear caused by the pulling of the optical cable body 1 or contact with other objects during use, and thus improving the service life of the optical cable body 1.

[0032] In use, the elastic rubber strip has good bending resistance, giving the optical cable body 1 good bending resistance. The first bending strip wraps around multiple cable cores and the inner sleeve, thus protecting the cable cores. When the optical cable body 1 is subjected to bending force, it can effectively reduce the phenomenon of cable core breakage due to bending. Furthermore, the second bending strip further improves the bending resistance of the optical cable body 1. When the optical cable is stretched, the tensile sleeve made of fiberglass tape effectively improves the tensile strength of the optical cable body 1, making the cable core less susceptible to damage. When the optical cable body 1 is in a state of tension... In high-temperature environments, the flame-retardant sheath made of silicone rubber gives the optical cable a good flame-retardant effect, enabling it to be used normally even in high-temperature environments. Fluororubber has good corrosion resistance, and the corrosion-resistant sheath made of fluororubber can improve the corrosion resistance of the optical cable body 1, thereby enabling the optical cable body 1 to better adapt to different environments and improve its service life. When the optical cable is pulled or comes into contact with other objects during use, the wear-resistant strip made of polytetrafluoroethylene plastic strips makes the friction coefficient of the optical cable body 1 low, thereby reducing the wear on the optical cable body 1 and thus improving the service life of the optical cable body 1.

[0033] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
