Abstract

The invention discloses a silver-plated copper strip wrapping structure of a stable-phase cable, manufacturing equipment and a preparation method thereof. According to the silver-plated copper strip wrapping structure of the stable-phase cable, an inner conductor is wrapped with an insulating layer, silver-plated copper strips are arranged outside the insulating layer, an inclination angle is formed between each silver-plated copper strip and the insulating layer, and the silver-plated copper strips are sequentially staggered. And the other layer of silver-plated copper strip is arranged belowthe upward inclined side of the silver-plated copper strip. According to the equipment of the silver-plated copper strip wrapping structure of a stable-phase cable, a wrapping machine comprises a pressing rod, thimbles are inserted into the two ends of the pressing rod, cover plates are installed at the two ends of the pressing rod through the thimbles, and an inward V-shaped slope groove is formed in the surface of the pressing rod on one side of the pressing rod. On the basis of low-density polytetrafluoroethylene insulation coating, a silver-plated copper strip wrapping material, silver-plated copper strip wrapping equipment, a novel wrapping tool and a novel process act together for processing. By using the silver-plated copper strip wrapping structure, the tightness inside the silver-plated copper strip wrapping layer is improved, and the binding force between the silver-plated copper strip wrapping layer and the insulating layer is increased.

Description

technical field [0001] The invention relates to the field of cable preparation, in particular to a silver-plated copper tape wrapping structure for a phase-stable cable, manufacturing equipment and a preparation method thereof. Background technique [0002] With the rapid development of the field of national defense and military industry, phase-stable cables are more and more widely used in electronic countermeasures, radar and other occasions due to their superior phase stability, low loss, high and low temperature resistance, and chemical environment corrosion resistance. [0003] At present, the domestically produced phase-stable cables can meet the basic needs of users such as VSWR, attenuation, capacitance, and impedance. However, after bending or long-term high and low temperature effects, the internal structure of the cable has poor stability, large phase changes, and attenuation during vibration. huge change. Therefore, it is necessary to design a new type of silver...
