Description

Technical Field

[0001] The utility model belongs to the field of high-frequency, high-definition, large-flow data information communication and equipment control network transmission wires for civil television broadcasting, ships and offshore platforms, and specifically relates to an integrated audio and video power distribution wire for broadcasting and television. Background Art

[0002] Existing communication data cables typically use optical fiber cables, Category 6a, and Category 7 data network cables for high-frequency communication. However, the outer sheaths and insulation of optical fiber cables and high-frequency data network cables are made of polyolefin materials. Civilian television broadcasting relay stations are often built high in the mountains, where humidity is high and temperatures are low. Control cables for heat-generating components such as engines and generators on ships and other equipment not only face complex, corrosive environments with high humidity and high salinity, but also operating temperatures exceeding 200°C. Ordinary polyolefin insulation and sheathing materials will melt instantly. Existing optical fiber cables have very high installation requirements, especially at the connectors. In static wiring applications, optical fiber products offer significant advantages such as high throughput, long service life, and stable signals. However, in mobile equipment, optical fiber products face technical challenges such as limited bend radius due to optical signal refraction requirements and significant signal attenuation caused by slight connector misalignment, which present difficult-to-solve technical problems in practical applications. Currently, the most advanced Category 7 data network cables utilize manufacturing technologies such as pair balancing, channel-specific shielding, and electromagnetic interference-resistant braided shielding, enabling data transmission capabilities of 1000 MHz and throughput exceeding 10 GB. However, due to material and structural limitations, the product cannot adapt to the harsh working environment of high humidity, below -40℃ and above 200℃ in high-end equipment such as aerospace and ships, and may become a dangerous source of failure for expensive television broadcasting, ships and other equipment at any time.

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0019] refer to Figure 1 An embodiment of the utility model proposes an integrated wiring cable for audio, video and power distribution for broadcasting and television, comprising: an outer sheath 6, a cross-linked silicone rubber sheath 5 is sheathed inside the outer sheath 6, and an air-cooling tube 4, an audio harness 3, a video wire core 2 and a power distribution wire core 1 are wrapped inside the cross-linked silicone rubber sheath 5.

[0020] like Figure 1 As shown, two power distribution cores 1, two video cores 2, an audio harness 3 and two air-cooling tubes 4 are arranged laterally at intervals, wherein the two air-cooling tubes 3 are adjacent to the two power distribution cores 1 and the two video cores 2, respectively, and are used to cool the power distribution cores 1 and the video cores 2; the power distribution core 1, the video core 2, the audio harness 3 and the air-cooling tubes 4 are wrapped with a cross-linked silicone rubber sheath 5, and the cross-linked silicone rubber sheath 5 is wrapped with an outer sheath 6.

[0021] The audio harness 3, video cable core 2, and power distribution cable core 1 facilitate modular installation, reducing costs and saving maintenance time. They also offer robust signal transmission capabilities and can provide operating current for low-power electrical appliances. The cross-linked silicone rubber sheath 5 is cold-resistant and corrosion-resistant, featuring low electromagnetic loss, high tensile strength, and excellent corrosion and temperature resistance. This cold-resistant and corrosion-resistant cross-linked silicone rubber sheath has a maximum operating temperature range of -120°C to 350°C and is commonly used in polar expedition equipment. The outer sheath 6 is woven from a double layer of highly flexible, high-strength glass fiber with excellent chemical resistance, excellent electrical properties, and high flexibility. This type of material is commonly used for sheathing in ships and avionics. This material ensures long-term operation in temperatures between -80°C and 300°C, and can be temporarily used in operating environments between -120°C and 350°C.

[0022] refer to Figure 1 According to an embodiment of the present invention, the outer sheath 6 is a flexible glass fiber braided outer sheath.

[0023] The outer sheath 6 is constructed from a double-layer, highly flexible, high-strength fiberglass braid, offering excellent chemical resistance, superior electrical properties, and high flexibility. This material is commonly used for sheathing in ships and avionics. It guarantees long-term performance in operating temperatures ranging from -80°C to 300°C, and temporary use in operating environments of -120°C to 350°C.

[0024] Outer sheath 6, a flexible braided glass fiber outer sheath, is a key component for ensuring product structural stability. Made of soft braided glass fiber filaments, it is woven onto the outer layer of the cable with a density of no less than 95%. This ensures a stable product structure for cables of varying specifications. The thickness of the flexible braided glass fiber outer sheath increases by 0.5mm for every 10cm increase in product circumference. Adjusting the thickness of the flexible braided glass fiber outer sheath can be achieved primarily through two methods: 1. Selecting different numbers of flexible glass fiber filaments to weave an outer sheath of varying thickness; 2. Selecting the same number of flexible glass fiber filaments to weave an outer sheath of the same thickness, increasing or decreasing the number of braided layers to achieve the desired outer sheath thickness.

[0025] refer to Figure 1 and Figure 2 According to an embodiment of the present invention, the power distribution core 1 includes a silver-plated copper conductor 101, the silver-plated copper conductor 101 is sheathed with a heat-resistant cross-linked silicone rubber insulation layer 102, and the heat-resistant cross-linked silicone rubber insulation layer 102 is provided with a graphite-coated shielding layer 103.

[0026] Power distribution line core 1 uses 0~2.5mm 2 Annealed silver-plated copper flexible conductors provide power for lighting, low-power propulsion, and other applications for instruments and equipment on ships and offshore equipment. The power distribution cable core 1 is sheathed in a heat-resistant, cross-linked silicone rubber insulation layer 102. This layer offers low electromagnetic loss, high tensile strength, and excellent corrosion and temperature resistance, ensuring low attenuation, low impedance, and high clarity for ultra-high-frequency data currents while maintaining stable capacitance and wave velocity ratio. A highly conductive graphite-coated shielding layer 103 is coated on the surface of the heat-resistant, cross-linked silicone rubber insulation layer 102, providing shielding against high-frequency interference signals.

[0027] refer to Figure 1 and Figure 3 According to an embodiment of the present invention, the video cable core 2 includes a twisted silver-plated copper conductor 201, the twisted silver-plated copper conductor 201 is sheathed with a high-density polyolefin insulation layer 202, and the high-density polyolefin insulation layer 202 is wrapped with an aluminum foil shielding layer 203.

[0028] The stranded silver-plated copper conductor 201 utilizes stranded annealed silver-plated copper, which is highly flexible and allows for precise twisting. Its surface is also round and smooth. The high-density polyolefin insulation layer 202 surrounding the stranded silver-plated copper conductor 201 provides a high-strength bonding layer, ensuring proper operation of the conductor core even in extreme temperatures. The aluminum foil shield 203 utilizes a self-adhesive aluminum foil wrapping, providing excellent structural stability and shielding against medium- and high-frequency pulse interference in the 0-1000 MHz range.

[0029] refer to Figure 1 and Figure 4 According to one embodiment of the present invention, the audio harness 3 includes a plurality of soft silver-plated copper conductors 301, each soft silver-plated copper conductor 301 is sheathed with a cross-linked silicone rubber insulation layer 302, the cross-linked silicone rubber insulation layer 302 is sheathed with an aluminum foil wrapped shielding layer 303, and the outermost layer of the audio harness 3 is sheathed with a self-adhesive aluminum foil shielding layer 304.

[0030] The soft silver-plated copper conductor 301 is a finely stranded copper conductor, and the cross-linked silicone rubber insulation layer 302 can operate normally under extreme temperatures. In addition, in order to prevent signal leakage, an aluminum foil wrapped shielding layer 303 is provided outside the cross-linked silicone rubber insulation layer 302 of each finely stranded soft silver-plated copper conductor 301. Finally, a self-adhesive aluminum foil shielding layer 304 is wrapped around the audio wiring harness 3 consisting of multiple soft silver-plated copper conductors 301 provided with cross-linked silicone rubber insulation layers 302 and aluminum foil wrapped shielding layers 303. This ensures that the audio wiring harness 3 has an excellent shielding effect against medium and high frequency pulse interference in the range of 0 to 1000 MHz.

[0031] refer to Figure 1 According to an embodiment of the present invention, the air-cooling tube 4 is a steel spring tube.

[0032] The air-cooling tube 4 is a dense spring tube made of high-strength and high-elasticity ultra-thin rectangular spring steel. It has high strength, good flexibility and excellent tensile strength. During use, it can take away the heat generated inside the cable in time to ensure that the cable works within a reasonable temperature range. At extremely low temperatures, it can also send the hot air generated by the heating equipment into the cable to ensure that the cable works normally at extremely low temperatures outdoors.
