Aluminum foil coating process of high-frequency and high-speed cable and corresponding production structure of aluminum foil coating process

Abstract

The invention provides an aluminum foil coating process of a high-frequency and high-speed cable. An aluminum foil uniformly wraps an outer surface of an inner core, so that the whole inner core is uniformly coated, the outer surface is smooth after coating, and the shielding uniformity is ensured. The production line can be suitably used for coating an oval or flat inner core and is high in universality. The aluminum foil coating process is characterized in that the inner core and the aluminum foil are synchronously input into a wrapping jig, the inner core penetrates through the center of the wrapping jig, and the aluminum foil is accommodated in the outer surface of the inner core step by step along an inner wall of the wrapping jig.

Description

technical field [0001] The invention relates to the technical field of production of high-frequency and high-speed cables, specifically the aluminum foil coating process of high-frequency and high-speed cables. The invention also provides a production structure corresponding to the aluminum foil coating of the high-frequency and high-speed cables. Background technique [0002] High-frequency and high-speed cables need to be coated with a layer of aluminum foil on the outer layer of the inner core. In the prior art, the coating is generally carried out through a winding process. Pitch, resulting in uneven outer surface after coating, and uneven coating, which makes the shielding performance uneven. The pitch changes due to the difference in overlap, resulting in a change in wavelength. When the wavelength resonates with the natural wavelength of the wire The time and frequency are obviously damaged, resulting in defects in shielded high-speed wires and cables; and the origina...

Pitch, resulting in uneven outer surface after coating, and uneven coating, which makes the shielding performance uneven. The pitch changes due to the difference in overlap, resulting in a change in wavelength. When the wavelength resonates with the natural wavelength of the wire The time and frequency are obviously damaged, resulting in defects in shielded high-speed wires and cables; and the original winding process can only cover circular inner cores, and cannot cover oval or flat inner cores, and its versatility is poor
