Description

A kind of Aero-Space sheath composite cable

Technical field

The utility model belongs to electric wire field, is specifically related to a kind of Aero-Space sheath composite cable.

Background technology

Each root cable that Aero-Space are used has own corresponding weight and volume, its quality of cable and the volume that are applied in aeronautical and space technology service system have certain restriction, thereby the quantity that makes cable also needs to be limited, thereby find comprehensive bunch of cables, can effectively solve cable space and weight issue.And along with the raising of people's environmental consciousness and the quickening of Chinese society economic construction paces, low-smoke halogen-free inflaming-retarding cable is widely used in each important department and public place.When breaking out of fire, during cable fire, do not discharge corrosive gas, and light transmission is good, and rescue work is very helpful, can reduce to a great extent casualties and property loss.Now need to develop a kind of composite cable, not only make wiring easily, can guarantee cable-flame retardant, low temperature resistant, anti-oxidant, soft, environmental protection simultaneously, take up room littlely, collect data wire and holding wire one, easy to install.

Utility model content

For meeting user's instructions for use, the purpose of this utility model is to provide a kind of Aero-Space sheath composite cable, and it is reasonable in design, simple in structure, fire-retardant, low temperature resistant, anti-oxidant, soft, environmental protection, take up room little.

Scheme of the present utility model is as follows: a kind of Aero-Space sheath composite cable, cable center's own centre line group, center line group includes two insulated wire cores, insulated wire cores comprises multiply bunchy silver-plated copper conductor, at described conductor, extrude perfluoroethylene-propylene insulating barrier outward, wrapped aluminium platinum layer after two insulated wire cores pair twists, aluminium platinum layer weaves tin-coated copper screen outward;

Described center line group and other four small bore insulated wire cores I and two heavy in section insulated wire cores II are twisted into cable core, described small bore insulated wire cores I comprises multiply bunchy silver-plated copper conductor I, in described conductor I, extrude perfluoroethylene-propylene insulating barrier I outward, two heavy in section insulated wire cores II comprise multiply bunchy silver-plated copper conductor II, in described conductor II, extrude perfluoroethylene-propylene insulating barrier II outward;

The outside of cable core is coated with lapping layer, total screen, restrictive coating from inside to outside successively.

Further, total screen of described cable is tin-coated copper screen.

Further, the restrictive coating material of described cable is fire-retardant low temperature resistant low smoke, zero halogen sheath.

The beneficial effects of the utility model: the utility model construction of cable is simple, be suitable for suitability for industrialized production, there is good anti-flammability, resistance to low temperature, non-oxidizability, softness, environmental protection, take up room little, by integrated to data wire and holding wire, the convenient various signals of carrying between each instrument.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

A kind of Aero-Space sheath composite cable, cable center's own centre line group, center line group includes two insulated wire cores, insulated wire cores comprises multiply bunchy silver-plated copper conductor 1, outside described conductor 1, extrude perfluoroethylene-propylene insulating barrier 2, wrapped aluminium platinum layer 3 after two insulated wire cores pair twists, the outer braiding tin-coated copper of aluminium platinum layer 3 screen 4; Described center line group and other four small bore insulated wire cores I and two heavy in section insulated wire cores II are twisted into cable core, described small bore insulated wire cores I comprises multiply bunchy silver-plated copper conductor I 5, outside described conductor I 5, extrude perfluoroethylene-propylene insulating barrier I 6, two heavy in section insulated wire cores II comprise multiply bunchy silver-plated copper conductor II 7, extrude perfluoroethylene-propylene insulating barrier II 8 outside described conductor II 7; The outside of cable core is coated with lapping layer 9, total screen 10, restrictive coating 11 from inside to outside successively.

In concrete enforcement, total screen 10 of described cable is tin-coated copper screen, and restrictive coating 11 materials of described cable are fire-retardant low temperature resistant low smoke, zero halogen sheath.

Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and revise; when its function producing does not exceed spiritual that specification contains yet, all should be within protection range of the present utility model.
