Abstract
The utility model discloses an aerospace cable, which is made of first insulating power line cores, second insulating power line cores, a PTFE wrapping layer, an alloy wire shielding layer and a ceramic fluorine plastic outer sheath. Each first insulating power line core is formed by extruding a silver-copper alloy flexible conductor with a fluorine plastic insulating layer; each second insulating power line core is formed by extruding a silver-copper alloy flexible conductor with a cross linked polyethylene insulating layer; the four second insulating power line cores are arranged in a square, and the four first insulating power line cores are arranged in a line and pass through the central portion of the square formed by the second insulating power line cores; the PTFE wrapping layer wraps the first insulating power line cores and the second insulating power line cores to form a cable core; the central portion of the cable core is provided with a natural rubber baffle; and the ceramic fluorine plastic outer sheath and the alloy wire shielding layer are extruded onto the cable core sequentially from outside to inside. Compared with a traditional silver-plated cable core, the aerospace cable has better electrical conductivity, shielding properties and mechanical properties.
Description
Technical field
The utility model relates to field of aerospace technology, relates in particular to a kind of cable for aerospace.
Background technology
?aviation refers to the navigation activity of aircraft in earth atmosphere, and space flight refers to the navigation activity of aircraft in cosmic space, exoatmosphere.Aerospace achievement has been concentrated the numerous new achievement of science and technology.Aerospace operations up to now, although also just the mankind leave initial several steps of this cradle of the earth, its effect is far beyond science and technology field, and politics, economic, military so that human society life have all been produced extensively and far-reaching influence.Be used at present aerospace electric wire and mainly adopt silver-plated copper core conductor, particular/special requirement for aerospace field to cable, need to develop the more excellent product of product conductivity, shielding properties and mechanical performance, to guarantee aerospace equipment normally operation in particular surroundings.
Utility model content
According to above-mentioned situation, the utility model object is to provide a kind of cable for aerospace.
Scheme of the present utility model is as follows: a kind of cable for aerospace, it is made up of insulated power core one, insulated power core two, PTFE lapping layer, B alloy wire screen and ceramic fluoroplastics oversheath, and described insulated power core one is to extrude yellow gold flexible conductor by fluoroplastic insulation layer to form; Described insulated power core two is to extrude yellow gold flexible conductor by cross-linked polrvinyl chloride insulating barrier to form; Four thoroughly do away with two one-tenth " mouth " fonts of edge power core arranges, in the middle of " mouth " font that 11 linear array of four eradication edge power cores forms through insulated power core two; Described PTFE lapping layer is coated on insulated power core one and becomes cable core with on insulated power core two; In the middle of described cable core, be provided with natural rubber dividing plate; Described ceramic fluoroplastics oversheath and B alloy wire screen are extruded on cable core successively from outside to inside.
The beneficial effects of the utility model: the utility model is compared with traditional silver-plated core, has more excellent conductivity, shielding properties and mechanical performance.
