Abstract
The utility model discloses an ultra-light cable for aerospace. The ultra-light cable is characterized in that a silver-plated copper stranded conductor is employed; an irradiation cross-linking ethylene-tetrafluoroethylene (XETFE) insulating layer is arranged on the surface of the silver-plated copper stranded conductor to form a cable core; a silver-plated copper flat wire braiding shielding layer is arranged outside the cable core; and an irradiation XETFE sheath is arranged on the outer surface of the cable. The ultra-light cable is small in size, light in weight and irradiation-resistant and can meet requirements for cables in the field of aerospace.
Description
Technical field
The utility model relates to cable, the cable that more particularly connects in particular for the aircraft internal electrical.
Background technology
Aerospace field has for employed cable and much is different from the conventional specific requirement of using cable, comprising: volume is little, in light weight, anti-irradiation etc.Normal cable in the prior art can not satisfy these requirements well.
Summary of the invention
The utility model is for avoiding above-mentioned existing in prior technology weak point, providing a kind of Aero-Space that satisfy the Aero-Space particular requirement that aim to use the microlight-type cable.
The utility model adopts following technical scheme for the technical solution problem:
The utility model Aero-Space with the design feature of microlight-type cable are: said employing silver-plated copper stranded conductor; Cross-linking radiation XETFE insulating barrier is set on the surface of said silver-plated copper stranded conductor forms cable core; At the outer setting silver-plated copper lenticular wire woven shield of said cable core, the appearance of said cable is provided with cross-linking radiation XETFE sheath.
Compared with present technology, the utility model beneficial effect is embodied in:
1, the utility model adopts the lenticular wire braid shielded.This series products that present domestic electric wire producer produces is round line braid shielded, and circle line braid shielded effect is relatively poor, and weight is heavy than the lenticular wire braid shielded.Braid shielded uses circle line minimum outer diameter to be Φ 0.1mm, and braid shielded is generally 0.07mm with the thickness of lenticular wire, even littler.Therefore, adopt the screen of lenticular wire braiding, on the basis that guarantees properties of product, further reduced the weight and the volume that has reduced product of product as cable.
2, conductor adopts the silver-coated copper wire stranded conductor in the utility model, and stranded conductor can improve the pliability of conductor, compare with single conductor, and easy fracture not, coefficient of safety is high.Silver-plated in copper conductor outside is in order to improve the temperature resistant grade of conductor, and the silver-plated copper conductor can bear 200 ℃ of high temperature for a long time.
3, insulating barrier and sheath all adopt the XETFE material in the utility model.The XETFE material is a kind of of fluoroplastics, and this material is on the basis of ETFE material, adds compositions such as crosslinking agent, forms through overmulling manufacturing grain.The molecular structure of material is a linearity molecular structure.This material just can anti-150 ℃ of high temperature before the cross-linking radiation, and XETFE density in high-temperature insulation material is little (is merely 1.73g/cm
3), in light weight, anti-irradiation, dielectric property are good, therefore are particularly suitable for as insulation and the sheath material of Aero-Space with electric wire.
4, insulating barrier and sheath change original linearity molecular structure into the space multistory network structure in the utility model after electron accelerator irradiation is crosslinked.Space network has further improved the performance of products index.Especially improved the temperature resistant grade of this product, be increased to 200 ℃ by 150 ℃.Improved the tensile strength of cable insulation and restrictive coating simultaneously.Cable after the process electron accelerator irradiation is crosslinked, reliability is higher, is more suitable for the little lightweight requirement of aerospace field volume.
5, the utility model stand 5 * 105Gy (behind 5 * 107rad) irradiation doses, still have reliable electrical property, can stand to exchange 50Hz, 2500V, the 1min voltage test does not puncture.
Description of drawings
Fig. 1 is the utility model structural representation.
Label among the figure: 1 silver-plated copper stranded conductor; 2 cross-linking radiation XETFE insulating barriers; 3 silver-plated copper lenticular wire woven shields; 4 cross-linking radiation XETFE sheaths.
Embodiment
Referring to Fig. 1; Aero-Space with the design feature of microlight-type cable are in the utility model: adopt silver-plated copper stranded conductor 1; Cross-linking radiation XETFE insulating barrier 2 is set on the surface of silver-plated copper stranded conductor 1 forms cable core; At the outer setting silver-plated copper lenticular wire woven shield 3 of cable core, the appearance of cable is provided with cross-linking radiation XETFE sheath 4.
In the practical implementation, silver-plated copper conductor 1 is to adopt the multiply silver-coated copper wire stranded; Cross-linking radiation XETFE insulating barrier 2 is to utilize electron accelerator irradiation crosslinked after adopting the XETFE high-temperature fusion to extrude; Silver-plated copper lenticular wire woven shield 3 is to adopt silver-plated circular copper wire is flattened processing; With the single doubling of silver-plated copper lenticular wire after flattening; Utilize the braiding of lenticular wire braiding machine to form then, cross-linking radiation XETFE sheath 4 is to utilize electron accelerator irradiation crosslinked after adopting the XETFE high-temperature fusion to extrude.
