Abstract
The utility model provides a high temperature resistant aviation wire. A tinplating copper conductor is externally connected with a polyimide film insulating layer which is formed by sintering polyimide film wrapped by adhesive at the temperature between 380 DEG C and 410 DEG C. A plurality of tinplating copper wires are twisted together to form the tinplating copper conductor; and the adhesive is organic silicon. The high-low temperature resistance, electric property and mechanical performance of the high temperature resistant aviation lead can meet the requirements of the aviation wire, no harmful gas is produced in the manufacture process, and the specific gravity is only 1.30-1.40 g/cm3, thereby greatly lightening the weight of the wire.
Description
Technical field
The utility model relates to lead, relates in particular to a kind of high temperature resistant aviation lead.
Background technology
The aviation lead that prior art is used all is to adopt tetrafluoro or perfluorinated material extrudes or form through wrapped sintering.Tetrafluoro or perfluorinated material are in the requirement that can satisfy the aviation lead aspect resistant of high or low temperature, mechanical strength, the electric property fully.Weak point is: (1) has hydrogen fluoride gas to emit in the manufacture process of cable, serious environment pollution, harm health of operators; Corrosion to equipment is very big, thereby causes the cost height.(2) proportion of fluoroplastics is bigger, reaches 2.1-2.2g/cm
3, concerning the airborne vehicle of high-speed flight, should reduce the weight that it forms former device by fair means or foul.
Summary of the invention
The purpose of this utility model provides and a kind ofly both can greatly reduce lead self proportion again in the requirement that can satisfy the aviation lead aspect resistant of high or low temperature, mechanical strength, the electric property fully, and lower-cost high temperature resistant aviation lead.
The purpose of this utility model can realize by following technical measures:
This is high temperature resistant aviation lead is made up of copper conductor and the insulating barrier that connects outward, and the tin-coated copper conductor is connected with the polyimide film insulating barrier that adopts the wrapped adhesive of polyimide film to form through 380-410 ℃ of sintering outward.
The purpose of this utility model also can realize by following technical measures:
Described tin-coated copper conductor is the many tinned copper wires that twist together; Described binding agent is an organosilicon.
Processing and fabricating of the present utility model: get the thin copper wire that meets the GB/T3956 requirement and plate one deck tin on the surface with the method for hot dip, the copper wire that will plate tin then as required can many twists together, wrapped one deck contains the polyimide film of binding agent on the good conductor of strand again, make conductive surface form integral insulation through 380-410oC high temperature channel sintering simultaneously, the high and low temperature resistance of this lead, electric property, mechanical performance all can satisfy the requirement of aviation lead, and manufacture process does not have pernicious gas and produces, and proportion is 1.30-1.40g/cm
3, greatly reducing the proportion of lead self, tensile strength is 94.5Mpa, long-term serviceability temperature is 260oC, does not puncture through 5 minutes with 2500V voltage.
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment:
Get the thin copper wire that meets the GB/T3956 requirement and plate one deck tin on the surface with the method for hot dip, the tinned copper wire 1 that will plate tin then as required many twist together, wrapped one deck contains the polyimide film 2 of organosilicon binding agent on the good tinned copper wire 1 of strand again, through 380-410oC high temperature channel sintering, make tinned copper wire 1 surface form the high temperature resistant aviation lead of polyimide film insulating barrier 2 simultaneously.
