Description

Technical Field

[0001] This utility model relates to the field of communication cable technology, specifically a lightweight, halogen-free, flame-retardant, and low-smoke-toxicity communication cable for ships. Background Technology

[0002] Chinese patent CN218548058U discloses a communication cable. This utility model selectively employs a foamed and extruded second insulation layer with low dielectric loss (small dielectric constant), thereby ensuring that the transmission characteristics of the communication cable meet product standard requirements. The communication cable of this application can balance the temperature resistance and communication performance of a communication cable. Furthermore, its high operational range and good practicality make it economically valuable.

[0003] However, existing communication cables are prone to signal crosstalk between multiple core wires, and communication cables are easily deformed by external environment, such as external forces. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lightweight, halogen-free, flame-retardant, and low-smoke-toxicity communication cable for ships, which solves the problems of signal crosstalk between multiple core wires and deformation caused by external forces.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight, halogen-free, flame-retardant, low-smoke toxicity communication cable for ships, comprising a cable body. The cable body, from the outside to the inside, is provided with a protective layer, an armor layer, and a wrapping layer. A Y-shaped limiting member is provided inside the wrapping layer. Positioning plates are fixedly connected to the Y-shaped limiting member and the inner wall of the wrapping layer via elastic elements. A shielding layer is fixed between the positioning plates. An insulating layer is wound inside the shielding layer. A copper conductor composed of multiple strands of ultra-fine copper wire is provided inside the insulating layer. A flame-retardant layer is provided between the shielding layer and the insulating layer. The flame-retardant layer is filled with a flame-retardant filler made of halogen-free, low-smoke polyolefin. An inert gas is provided inside the wrapping layer.

[0006] Preferably, an adsorption layer is fixed between the protective layer and the armor layer, the adsorption layer is filled with activated carbon particles, and a semi-circular wear-resistant block is fixed on the outside of the protective layer.

[0007] Preferably, the Y-shaped limiting member has a copper wire insulating layer wound inside.

[0008] Preferably, the flame-retardant filler is a thermosetting phenolic resin, and the elastic element is a buffer spring.

[0009] Preferably, a glass fiber layer is wound around the armor layer, and the armor layer is made of galvanized steel strip material.

[0010] Preferably, the outer protective layer is composed of low-smoke, halogen-free, low-toxicity, flame-retardant, radiation-crosslinked polyolefin.

[0011] Beneficial effects

[0012] This invention provides a lightweight, halogen-free, flame-retardant, and low-smoke-toxicity communication cable for ships. Compared with existing technologies, it has the following advantages:

[0013] (1) The shipboard lightweight halogen-free flame-retardant low smoke toxicity communication cable separates the copper conductor through the Y-type limiting component and limits the position of the copper conductor to reduce crosstalk and maintain impedance stability. At the same time, the elastic component can dilute and buffer the kinetic energy generated when the cable is squeezed by external force, thereby reducing the impact on the copper conductor and reducing the phenomenon of deformation of the copper conductor, thus ensuring the smoothness of information transmission.

[0014] (2) The shipboard lightweight halogen-free flame-retardant low smoke toxicity communication cable increases the wear resistance of the protective layer through the semi-circular wear-resistant blocks on the outside of the protective layer, and can also prevent damage to the cable body from external collisions, thereby increasing the service life of the cable body. The activated carbon particles inside the adsorption layer adsorb the toxic gases generated when a fire occurs, thereby reducing the emission of toxic gases. The glass fiber layer on the armor layer increases the extensibility of the armor layer, thereby improving its tear resistance. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides two technical solutions:

[0022] Figure 1-2 Figure 4 illustrates the first embodiment: a lightweight, halogen-free, flame-retardant, low-smoke toxicity communication cable for ships, comprising a cable body 1. The cable body 1 has, from the outside to the inside, a protective layer 2, an armor layer 3, and a wrapping layer 4. A Y-shaped limiting member 5 is provided inside the wrapping layer 4. Positioning plates 7 are fixedly connected to the Y-shaped limiting member 5 and the inner wall of the wrapping layer 4 via elastic members 6. A shielding layer 8 is fixedly provided between the positioning plates 7. An insulating layer 9 is wound inside the shielding layer 8. A copper conductor 10, composed of multiple strands of ultra-fine copper wire, is provided inside the insulating layer 9. The shielding layer 8... A flame-retardant layer 11 is provided between the insulating layer 9 and the flame-retardant layer 9. The flame-retardant layer 11 is filled with a flame-retardant filler and is made of halogen-free low-smoke polyolefin. The wrapping layer 4 is filled with an inert gas. The inert gas in the wrapping layer 4 can effectively achieve the flame-retardant effect, thereby improving its flame retardancy. The Y-shaped limiting member 5 is wrapped with a copper wire insulation layer 149. The copper wire insulation layer 149 can effectively reduce the occurrence of crosstalk, thereby improving its anti-interference ability. The flame-retardant filler is a thermosetting phenolic resin. The elastic member 6 is a buffer spring.

[0023] The copper conductor 10 is separated by the Y-shaped limiting member 5, which also limits the position of the copper conductor 10, reduces crosstalk and maintains impedance stability. At the same time, the elastic member 6 can dilute and buffer the kinetic energy generated when the cable is squeezed by external force, thereby reducing the impact on the copper conductor 10, reducing the deformation of the copper conductor 10, and thus ensuring the smoothness of information transmission.

[0024] Figure 1 and 3 The second embodiment is shown, and the main difference from the first embodiment is that: an adsorption layer 12 is fixed between the protective layer 2 and the armor layer 3, the adsorption layer 12 is filled with activated carbon particles, a semi-circular wear-resistant block 13 is fixed on the outside of the protective layer 2, a glass fiber layer 15 is wrapped around the armor layer 3, the armor layer 3 is made of galvanized steel strip material, and the outer protective layer is made of low smoke, halogen-free, low toxicity, flame-retardant, radiation-crosslinked polyolefin.

[0025] The semi-circular wear-resistant blocks 13 on the outside of the protective layer 2 increase the wear resistance of the protective layer 2 and also protect the cable body 1 from damage caused by external impacts, thereby increasing the service life of the cable body 1. The activated carbon particles inside the adsorption layer 12 adsorb the toxic gases produced during a fire, thereby reducing the emission of toxic gases. The glass fiber layer 15 on the armor layer 3 increases the extensibility of the armor layer, thereby improving its tear resistance.

[0026] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0027] During use, the copper conductor 10 is separated by the Y-shaped limiting member 5, which also limits the position of the copper conductor 10, reduces crosstalk and maintains impedance stability. At the same time, the elastic member 6 can dilute and buffer the kinetic energy generated when the cable is squeezed by external force, thereby reducing the impact on the copper conductor 10. The semi-circular wear-resistant block 13 on the outside of the protective layer 2 increases the wear resistance of the protective layer 2 and can also prevent damage to the cable body 1 from external collisions. The activated carbon particles inside the adsorption layer 12 adsorb toxic gases generated in the event of a fire. The glass fiber layer 15 on the armor layer 3 increases the elongation of the armor layer, thereby improving its tear resistance.
