Problems solved by technology

[0003] Due to the special folding and pressing characteristics of flexible solar wings, the installation size of the circular cross-section wires commonly used on rigid or semi-rigid solar panels cannot meet the use requirements of the flexible solar wing battery circuit, and the circular cross-section wires themselves have no structure. Elongation, without the protection of other stress relief measures, it cannot work in the space orbit thermal environment with frequent high and low temperature alternating
[0004] At present, the cables used in space solar cell arrays are circular cross-section cables, and the diameter of the cables is relatively thick, which cannot meet the application requirements of special models for thin cables; and the existing circular cross-section cables themselves do not have structural elongation. There is a certain size margin to meet the in-rail tension of the cable due to the alternating thermal stress of the space

Embodiment Construction

[0023] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0024] see figure 1 , a thin cable with a braided structure for a space solar cell array, the thin cable includes an M-spindle wire harness, the above-mentioned M-spindle wire harness is woven into a thin-shaped cable through a single-layer braiding technique, and each ingot wire harness is composed of N copper wires, usually Under the condition, N copper wires do not need to be twisted, that is, they are in parallel relationship; under the premise of satisfying the current transmission function of the conductor material, the diameter range of each copper wire is 0.02mm-0.3mm; where: M and N are A natural number greater than 2. In actual use, the thin cable section generally adopts the following two sizes:

[0025] One: The width range of t...

Abstract

The invention discloses a braided structure thin cable applied to a space solar battery array, and relates to the technical field of space solar array power transmission. The cable is characterized in that the thin cable is formed by braiding M wiring harnesses through a single layer braiding technology; each wiring harness is composed of N copper wires; the diameter range of each copper wire is between 0.02mm and 0.3mm; and M and N are natural numbers greater than two. According to the invention, the thin cable is formed by braiding M wiring harnesses through the single layer braiding technology; each wiring harness is composed of N copper wires; compared with a traditional single copper wire, the thin cable has better structural elongation; the thin cable has great adaptability for a complex thermal stress environment caused by space high and low temperature alternation; specific stress reduction measures are no longer designed; an installation process is easy; and the reliability and the safety of a product are improved.

Description

technical field [0001] The invention relates to the technical field of power transmission for space solar cell arrays, in particular to a braided thin cable for space solar cell arrays. Background technique [0002] At present, the on-board cables commonly used on rigid or semi-rigid solar panels are circular cross-section wires. For rigid or semi-rigid solar cell arrays whose board spacing exceeds 2cm when folded, the installation of circular cross-section wires with a diameter of no more than 2mm The space is very ample, and the cables on the rigid or semi-rigid board are bent and arranged in bundles and sections, forming a natural stress-relief bend, which can meet the requirements of stress-relief on the cables on the board in the alternating high and low temperature environment of the space. [0003] Due to the special folding and pressing characteristics of flexible solar wings, the installation size of the circular cross-section wires commonly used on rigid or semi-ri...
