Abstract
The invention relates to a method for producing a low-attenuation corrugated coaxial cable, which comprises steps of (1) preparing an inner conductor of the cable, drawing by a diamond mold, cleaning the inner conductor through ultrasonic wave for ensuring high cleanness of the inner conductor surface; (2) performing an insulation process, wherein an insulator is formed by high-pressure carbon dioxide, and realizing a foaming degree above 80%, and (3) forming an outer conductor of the cable by aluminum belt material through continuous rolling forming, forming a pipe by a diamond alloy mold, and welding. The method of the invention has beneficial effects of small product weight, small transmission attenuation, small echo loss and convenient transportation and mounting. A copper outer conductor is changed to an aluminum outer conductor. Original N2 foaming on an insulator is changed to CO2 foaming. In production process, polytetrafluoroethylene is combined with a diamond coating mold for improving surface smoothness of the aluminum outer conductor, thereby reducing signal transmission interference changing dielectric constant of PE and reducing transmission attenuation.
Description
Technical field
The present invention relates to a kind of production method of coaxial cable.
Background technology
Co-axial cables transport signal mainly kelvin effect, what lean on is that conductive surface carrys out signal transmission, inner wire outer surface and the outer conductor inner surface of what Signal transmissions leaned at high frequencies is coaxial cable.What present coaxial cable generally adopted is copper outer conductor, and the transmission attenuation of copper outer conductor is comparatively large, and weight is large simultaneously, and cost is higher.
Summary of the invention
The object of this invention is to provide a kind of production method of low decay corrugated coaxial cables, its coaxial cable lighter weight of producing, transmission attenuation is less.
For reaching the present invention of this object by the following technical solutions:
A production method for low decay corrugated coaxial cables,
(1) prepare cable inner conductor, adopt Diamond dies drawing, then cleaned by ultrasonic wave inner conductors, guarantee inner wire surface clean;
(2) insulating process, insulator adopts high-pressure carbon dioxide foaming, and foam degrees reaches more than 80%;
(3) outer conductor of cable adopts aluminium strip material, is welded through continuous rolling shaping and diamond alloy mould Cheng Guanhou.
The beneficial effect of this product: lighter in weight, transmission attenuation is little, return loss is little, be convenient to transport installs.Change copper outer conductor into aluminium outer conductor.Insulator is by original N
2foaming changes CO into
2foaming.In production technology, we adopt polytetrafluoroethylene and diamond coatings mould to combine and improve the fineness on aluminium outer conductor surface, and reduce Signal transmissions and obstruct, the dielectric constant changing PE makes transmission attenuation less.
Embodiment
A production method for low decay corrugated coaxial cables,
(1) prepare cable inner conductor, adopt Diamond dies drawing, then cleaned by ultrasonic wave inner conductors, guarantee inner wire surface clean;
(2) insulating process, insulator adopts high-pressure carbon dioxide foaming, and foam degrees reaches more than 80%,
(3) outer conductor of cable adopts aluminium strip material, is welded through continuous rolling shaping and diamond alloy mould Cheng Guanhou.
The lighter in weight that the present invention produces, transmission attenuation is little, return loss is little, be convenient to transport installs.Change copper outer conductor into aluminium outer conductor.Insulator is by original N
2foaming changes CO into
2foaming.In production technology, we adopt polytetrafluoroethylene and diamond coatings mould to combine and improve the fineness on aluminium outer conductor surface, and reduce Signal transmissions and obstruct, the dielectric constant changing PE makes transmission attenuation less.
This product can adapt to the wireless network of current high speed development, for user provides high-quality mobile service; This product, while remaining 50 Ω corrugated copper tube outer conductor radio frequency coaxial cable mechanical performances, alleviates product weight, too increases the flexibility selecting cable product, has obviously cost advantage.The corrugated copper tube outer conductor radio frequency coaxial cable that this product 50 Ω Sylphon outer conductor radio frequency coaxial-cable is used for substituting specification of the same race has very large advantage.
