Abstract

The invention provides a flat-type double-layer power signal transmission cable and a forming method of the cable. The flat-type double-layer power signal transmission cable comprises a middle insulating layer which is a polyimide film, an upper layer power signal transmission layer pasted to the upper surface of the middle insulating layer, a lower layer power signal transmission layer pasted to the lower surface of the middle insulating layer, an upper layer insulating layer pasted on the other surface of the upper layer power signal transmission layer, a lower layer insulating layer pasted on the other surface of the lower layer power signal transmission layer, an upper layer elemental oxygen protective layer located on the other surface of the upper layer insulating layer, and a lower layer elemental oxygen protective layer located on the other surface of the lower layer insulating layer, wherein the thickness of the middle insulating layer is 25 microns to 75 microns, and the upper layer power signal transmission layer and the lower layer power signal transmission layer are made of copper material. The flat-type double-layer power signal transmission cable can meet the large-power and multipath signal transmission requirements for solar cell arrays on spacecrafts.

Description

[0001] technical field [0002] The invention belongs to the research in the technical field of space-level power signal transmission, and relates to a flat double-layer power signal transmission cable and a forming method thereof. Background technique [0003] A solar cell is a semiconductor device that uses the photovoltaic effect to directly convert light energy into electrical energy. At present, many space vehicles use solar cell arrays to generate energy. [0004] The traditional power and signal transmission cables on space vehicles mainly use space-grade round wires. The development of future spacecraft requires large power, long cable transmission distances, and a large number of transmission power and signals. Wires have been unable to meet the application needs. [0005] The invention has small folded volume, long unfolded transmission distance, and multiple power and signal transmission channels. The flat cable can be mechanically fixed on the solar panel, wher...
