Four-core coaxial cable for aerospace and preparation method thereof

Abstract

The invention discloses a four-core coaxial cable for aerospace. The four-core coaxial cable comprises a cable core and a shielding layer; a strengthening core is arranged at the center of the cable core, the cable core is stranded through four coaxial wire cores and the strengthening core; each wire core is composed of a conductor wire and an insulating layer covered at the outside of the conductor wire; graphite conductive fabric is embedded at the periphery of the cable core, a the shielding layer is embedded at the outside of the graphite conductive fabric, and a jacket is extruded at theoutside of the shielding layer. The invention further provides a corresponding preparation method; the preparation method comprises the following steps: the graphite conductive cloth preparation: spraying super glue on a matrix cotton tape, grinding the raw material graphite into a piece, and rolling on a substrate, continuously rolling and tearing off the matrix cotton tape on the substrate, andfinally spreading the powered graphite, and rolling and molding; wire-wrapping process: wrapping the cable core by adopting the graphite conductive cloth, embedding the shielding layer and the jacketto obtain the finished product. Through the method for preparing graphene by simulating a mechanical method, the graphite is layered and adhered on the periphery of the cable core, the conductivity ofthe graphite conductive cloth is improved, the thickness of the graphite conductive cloth is reduced, and an electromagnetic shielding effect of the cable product is improved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a four-coaxial cable for aerospace and a preparation method thereof. Background technique [0002] As a new data bus, quad-coaxial cable has the following characteristics: compact structure, small footprint, high bandwidth, stable transmission signal, support for hot plugging, scalable data transmission rate, flexible and diverse topology, and full digital compatibility , can establish a peer-to-peer network, and supports both synchronous and asynchronous data transmission modes, etc., so it has been more and more widely used in the aviation field and weapon systems. [0003] As the operating speeds of aerospace computers continue to increase, the transmission speeds of externally connected devices also increase, placing new demands on cables. At present, there are no fully applicable products in China, mainly relying on imports, such as Tyco's CEC-RWC-18664, CEC-RWC-18634, CEC-R...
