Ultra-flexible flat cable wiring harness network for aerospace

Abstract

The invention discloses an ultra-flexible flat cable wiring harness network for aerospace. The ultra-flexible flat cable wiring harness network comprises a first wiring harness, a second wiring harness and a third wiring harness, which are formed in a crosslinked ethylene-tetrafluoroethylene copolymer carrier layer by extrusion molding, wherein the first wiring harness, the second wiring harness and the third wiring harness are formed by twisting 0.15mm pair twisted shielded wires and 0.3mm pair twisted shielded wires into beams and each beam is sequentially coated with a woven suture layer and an anti-tear silicone rubber protection layer on the periphery, wherein a wrapping layer, a polyolefin physical foaming layer, a woven layer and a crosslinked ethylene-tetrafluoroethylene copolymer outer sheath layer are coated at the outside of the crosslinked ethylene-tetrafluoroethylene copolymer carrier layer in sequence. The ultra-flexible flat cable wiring harness network disclosed by the invention is novel in structural design, the cable has flexibility and bending resistance, the operation of branch welding and other subsequent procedures is implemented easily, and the ultra-flexible flat cable wiring harness network has the advantages of high and low temperature resistance, weight, thermal shrinkage, excellent mechanical properties, salt mist resistance, dampness and heat resistance, excellent high-energy electron radiation resistance, and can improve the reliable energy and signal transmission in harsh environments.

Problems solved by technology

[0003] In order to meet the strict space requirements on the spacecraft, it is necessary to design a flat braided cable harness net; in order to reduce the occupied space and weight, the braided structure outside the traditional cable core, the softness and bending resistance of the cable harness net are relatively Poor, which makes it difficult for the cable to perform operations such as branch welding in the later stage; in addition, the high and low temperature resistance, weight, heat shrinkage and excellent mechanical properties of the cable are also relatively poor, and it does not have anti-salt spray, anti-humid heat and anti-high-energy electronic radiation characteristics, improving reliability in harsh environments where energy and signal transmission are not guaranteed
