Description
Technical field
The invention belongs to Power-line technology field, and in particular to a kind of 0.13mm for auto electric information transmission2Electric wire.
Background technology
Automotive wire bundle is connected to power supply and each electric component on automobile, and the information being responsible between each electrical appliance of vehicle is passed
Pass, and electric wire is the core of wirning harness.With the raising that people are required comprehensive vehicle performance, electrical appliance on automobile also towards
Diversified development, automotive wire bundle is also more and more numerous and more jumbled, and more intelligence systems are applied to automobile, the output of these intelligent controllers
The electric wire of automobile is designed interface and assembling proposes higher requirement.
Now, the cost pressure of automobile main frame maker is increasing, and smaller lighter wire can not only reduce cost, moreover it is possible to drop
Low complete vehicle weight, saves the use of material, reduces the oil consumption of automobile.No matter consider from technology, cost or from environmental angle, vapour
Wire size on car will be less and less.At present, the line footpath wire generally used on automobile is 0.22mm2, 0.35mm2, it is smaller
The electric wire of line footpath such as 0.13mm2Electric wire is the inexorable trend of electric wire industry future development, but 0.13mm2Electric wire its mechanical performance is such as
Low tensile strength is maximum obstacle, the 0.13mm of the technology of the present invention manufacture2Electric wire has in the case where ensureing its electrical property
The characteristics of tensile strength is high.
The content of the invention
The technical problems to be solved by the invention are to be directed to existing automobile 0.13mm2Its mechanical performance of electric wire such as tension is strong
There is provided a kind of high intensity 0.13mm for the problem of spending low2Electric wire replaces 0.22mm2Or 0.35mm2Electric wire, solves automobile main frame maker and exists
Being realized on the premise of not reducing wirning harness performance reduces the purpose of cost, and can reduce complete vehicle weight, and reduction raw material are used, protected
Retaining ring border, improves product competitiveness.
In order to solve the above technical problems, the present invention uses following technical scheme：
A kind of electric wire for automobiles, including insulating barrier and conductor cores, the insulating barrier surround the conductor cores, the conductor cores
By 7 copper-iron alloy monofilament mutually it is stranded formed, or the electric wire conductor cores by 6 copper-iron alloy monofilament and 1 copper-clad
Steel monofilament is mutually stranded to be formed, or the conductor cores of the electric wire are mutually twisted by 6 signal bronze monofilament and 1 copper covered steel monofilament
Close and formed；The diameter of the copper-iron alloy monofilament, copper covered steel monofilament and signal bronze monofilament is 0.16mm.
The content of the copper of the copper-iron alloy monofilament is 90~98%, and the content of iron is 2~10%.
The content of the copper of the copper covered steel monofilament is 20%, and the content of iron is 80%.
The content of the copper of the signal bronze monofilament is 99.7%, and the content of tin is 0.3%.
The insulating barrier is made up of metallocene PE.
The thickness of the insulating barrier is 0.2mm.
Beneficial effects of the present invention：(1) automobile 0.13mm of the present invention2Electric wire, solving automobile main frame maker is not reducing electricity
Being realized on the premise of wire harness performance reduces the purpose of cost, and obtained wire external diameter is small and high mechanical strength, and electric conductivity still may be used
Meet and require, and complete vehicle weight can be reduced, reduction raw material are used and oil consumption, and environmental protection improves product competitiveness.(2) originally
Invention is to start with using 0.13mm from the light-weight design of automobile2Electric wire replaces 0.22mm2、0.35mm2Electric wire, in the design
There is quality to mitigate and common 0.13mm2The intensity of electric wire does not reach 0.22mm2、0.35mm2The technical contradiction of the intensity of electric wire,
Reached using inventive principles of the TRIZ in theoretical by using this inventive principle of composite and improve metallic conductor intensity
Purpose, to ensure the electric conductivity replaced, using the relatively good iron of electric conductivity, the copper alloy of tin, by substantial amounts of checking and at present
The Cu alloy material that in the market is easily obtained finally determines the composition of copper alloy, while being closed by a copper covered steel and six roots of sensation copper
The compound stranded intensity for further increasing conductor of gold.(3) by the resource analysis method of nine theoretical TRIZ windows, analysis
Resource outside using conductor system is designed, and is used using the higher metallocene PE of intensity instead of current common wiring
Polyvinyl chloride, so as to finally realize the 0.13mm that makes of the present invention2The intensity of electric wire reaches 0.22mm2Or 0.35mm2Electric wire
The requirement of intensity.
