Manufacturing process of ultra-soft feed line inner conductor

Abstract

The invention relates to the field of communication, in particular to a manufacturing process of a novel ultra-soft feed line inner conductor. In the manufacturing process of the ultra-soft feed line inner conductor, the ultra-soft feed line inner conductor is formed by carrying out deep spiral pattern rolling by directly adopting a smooth copper pipe as a raw material; the oxygen content in a cast blank of the smooth copper pipe is controlled to be below 10ppm, and the phosphorus content is controlled to be below 30ppm; the wall thickness of the smooth copper pipe is 0.19-0.27 mm, and the tensile strength is 240-270MPa; and the elongation ratio A is not less than 45 percent. The manufacturing process of a coaxial cable inner conductor improves the production speed and the product quality of a traditional ultra-soft feed line inner conductor, the smooth copper pipe is used for directly rolling patterns to replace a series of original production working procedures of pattern rolling and the like after the welding of a copper tape reeling pipe, and the manufacturing process has the greatest advantage that the working procedures of edge cutting and welding of a copper tape are saved, thereby improving the production efficiency of the inner conductor and greatly reducing the loss of a copper material.

Description

technical field [0001] The invention relates to the communication field, in particular to a manufacturing process of a novel super-flexible feeder inner conductor. Background technique [0002] Super flexible feeder is a new generation of high-tech communication transmission components. Due to the spiral corrugated structure, the project product has the advantages of a very small bending radius, and is one of the most suitable short-range and indoor / outdoor jumper components for mobile communication systems and communication equipment. The project products can also be widely used in ground mobile communication, radio communication antenna feeder, ground base station antenna jumper, machine room feeder and antenna connection line, military data information transmission line, ultra-low frequency, AM and FM radio broadcasting system, ground microwave communication, Radar systems for aviation and navigation and portable communication systems such as strategies. In recent years...

AI Technical Summary

Problems solved by technology

The traditional super-flexible feeder inner conductor manufacturing process such as figure 1 As shown, because the inner conductor of the traditional ultra-flexible feeder is welded into a copper tube by argon arc welding of copper strips and then embossed into a spiral inner conductor, the loss of the copper strip is large, and there will be weld cracks, pinholes, and flashovers. And other poor welding quality problems, so that the electrical performance (especially the voltage standing wave ratio) of traditional super flexible feeder products fluctuates greatly and is unstable
