Abstract
A heat-resistant shielded cable for aviation is characterized in that a conductor has a twisting structure of a plurality of nickel plating, silver or tin plated soft copper filaments; a polyester-ether thermoplastic elastomer TPE-E insulating layer is extruded on the conductor so as to form an insulated conductor core; one insulated conductor core or a plurality of insulated conductor cores are twisted to form a cable so as to form a cable conductor; and the cable conductor is externally provided with a nickel plating, silver or tin plated copper weaving shielding layer, and a thin-wall sheath layer taking polyetherimide as materials is extruded on the surface. The heat-resistant shielded cable has combination properties of high/low temperature resistance, humidity resistance, weather resistance, ageing resistance, halogen free, phosphorus free, flame retardant property, electromagnetic interference resistance, softness and the like, can adapt to various working environment, and is suitable for being used as connecting electric wires of aerospace planes.
Description
Technical field
The utility model relates to the aviation cable, relates in particular to a kind of high temperature resistant aviation shielded type cable, belongs to technical field of electric wires and cables.
Background technology
Aerospace equipment has requirements such as volume is little, in light weight along with the raising requirement of equipment performance to special installation.As spacecraft electrical installation, instrument and meter connecting line, want that cube is little, to adapt to all kinds of adverse circumstances, ampacity big and to bear overload capacity strong, and require cable to have favorable mechanical physical property, electric property and lay conveniently, cable should have characteristics such as anti-electromagnetic shielding, fire-retardant, Halogen, oil resistant, heatproof, moisture-proof, and safety guarantee is had relatively high expectations.But existing normal cable can not satisfy this requirement.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of and can possess combination properties such as anti-high/low temperature, moisture-proof, weather-proof, ageing-resistant, Halogen, without phosphorus, fire-retardant and softness, can adapt to the high temperature resistant aviation shielded type cable of multiple different operational environment.
The utility model technical solution problem adopts following technical scheme:
The high temperature resistant aviation of the utility model is that conductor is the lay configuration of many nickel plating, silver or zinc-plated soft copper monofilament with the design feature of shielded type cable, extrudes polyester-ether thermoplastic elastomer TPE-E insulating barrier and constitute insulated wire cores on conductor; Constitute cable conductor with single insulated wire cores or by the stranded stranding of many eradications edge core; Nickel plating, silver or tinned copper wire woven shield are set, and to extrude with the Polyetherimide on the top layer be the thin-walled restrictive coating of material outside cable conductor.
So aviation that the utility model is high temperature resistant also exists with the design feature of shielded type cable:
The conductor that described soft copper monofilament constitutes is chosen as the 2nd class conductor or the 5th class conductor that meets GB/T3956.
Described conductor adopts regular lay configuration, and the twisted wire pitch is between 10-12 times.
The sectional area of described conductor is 0.08～8mm
2
Described insulated wire cores is the 2-4 core.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model adopts the conductor that nickel plating, silver or zinc-plated soft copper monofilament constitute, and can prevent the aging catalytic action of copper conductor to insulating barrier effectively, to guarantee the useful life of insulating barrier.Simultaneously, in plating nickel on surface, silver or the zinc-plated oxidation that also can effectively prevent soft copper monofilament conductor itself of soft copper monofilament, increase the security reliability in the use.
2, insulating material and sheath material are material with polyester-ether thermoplastic elastomer TPE-E material and Polyetherimide respectively in the utility model, have the chemical resistance of wide range, and it also has following performance:
(1) excellent heat resisting, heat-resisting peak reach 200 ℃, and lasting serviceability temperature is 150 ℃;
(2) splendid mar proof, electric property that it is good and mechanical performance satisfy the requirement of low-voltage cable fully;
(3) fabulous UV resistant performance;
(4) insulating barrier has lasting color retention after aging;
(5) have chemical substances such as favorable chemical resistance energy, ability mineral oil, soda acid, ozone;
(6) and have good flame retardancy, the sheath material oxygen index reaches 48, is higher than common fire proofing far away;
(7) insulation and sheath material mechanical performance and excellent electrical properties can be extruded thin layer, reduce cost, and reduce the cable volume;
(8) owing to be directly to extrude processing, do not need the equipment of extra preliminary treatment and reprocessing;
(9) because be thermoplastic, the processing of can regenerating, and the heat ageing process is very slow, and very big recycling value is arranged, and meets environmental protection spirit.
3, screen adopts the braided metal material in the utility model, and cable has shielding properties and softness preferably.
