Processing technology of coaxial cable

Abstract

The invention discloses a processing technology of a coaxial cable. The processing technology comprises the following steps of 1) arranging annular sleeves on two disc side walls of a disc, wherein the two annular sleeves are opposite to each other and can be pressed and slide out relative to the disc; 2) winding the processed semi-finished product of the coaxial cable on the disc to form a semi-finished disc; 3) allowing the annular sleeves to slide out of a side of the semi-finished disc to sleeve an outer side of the semi-finished disc; and 4) wrapping an isolation film on the semi-finisheddisc and at the peripheries of the annular sleeves so that external air and the semi-finished disc are isolated. By the processing technology, the annular sleeves can slide outwards and sleeve the periphery of the semi-finished disc after the semi-finished product is wound to form the semi-finished disc, the annular sleeves and the semi-finished disc can be simultaneously wrapped by the isolationfilm, the external air can be effectively isolated due to the presence of the annular sleeves sleeving the semi-finished disc, the external air is prevented from entering a gap between the disc and the semi-finished disc, and the method is good in oxidization-resistant effect.

Description

technical field [0001] The invention relates to the field of cables, in particular to the processing technology of coaxial cables. Background technique [0002] When coaxial cables are manufactured, semi-finished products (including the inner shielding layer, foam layer and outer shielding layer arranged in sequence from the inside to the outside) will be processed first, and the semi-finished products will be gathered on the plate, because the outer shielding layer is copper. It is easy to oxidize. If it is oxidized, it will seriously affect the performance of the coaxial cable. In order to improve the storage time of the semi-finished product, the outer surface of the semi-finished product wound on the tray is usually covered with an isolation film, so that the semi-finished product can be isolated from the air as much as possible. [0003] The tray includes a cylindrical part and circular plates distributed on both sides of the cylindrical part. In the existing form, the ...

AI Technical Summary

Problems solved by technology

[0003] The tray includes a cylindrical part and circular plates distributed on both sides of the cylindrical part. In the existing form, the isolation film cannot fit well with the two circular plates of the tray, and the air will flow from the circular plate and the disc. The gap between semi-finished products goes in, so the anti-oxidation effect is not ideal
