1.This aluminum conductor effectively can not only alleviate wire weight, reduces wire cost, and can effective pilot sectional area, is convenient to conductor laying installation, is widely used in the motor vehicles such as automobile.
Description
Technical field
The utility model relates to automobile-use cable, particularly relates to the aluminium matter distribution cable carrying out signal controlling and power transmission etc. on the motor vehicles such as automobile.
Background technology
For the motor vehicles such as automobile, vehicle body deadweight and integral vehicle cost evaluate two key indexs of its performance advantage and cost performance.The size of vehicle weight not only directly affects the fuel economy of vehicle and property safe and reliable to operation, but also determines the exhaust emissions amount of vehicle.
Along with high performance, the multifunction of automobile, the control circuit of various electronic equipment greatly increases, and the distribution cable of an automobile is all more than hundreds of rice.The wiring lengths such as the signal controlling cable on automobile and power transmission cable increase, take up room increase, thus strengthen complete vehicle weight and cost, and the increase of vehicle complete vehicle weight both can bring the increase of fuel consumption and the aggravation of tail gas discharge capacity, also can affect the braking ability of automobile, then have a strong impact on the fail safe of automobilism.The increase of automotive wiring harnesses cable, also bring the raising of auto cost, and the use cost of automobile and acquisition cost all directly can affect the desire to buy of consumer simultaneously; The increase of number of cables, can be also related at narrow space, the automobile installing space of complexity be convenient lays smoothly.In order to alleviate vehicle complete vehicle weight, the acquisition cost reducing automobile and use cost, people start trial aluminium and replace copper material to make automobile distribution cable.
Aluminium aboundresources, aluminium element takes up an area 7.73% of shell constituent content, and copper only takes up an area shell constituent content less than 0.01%, and thus the cost ratio copper of aluminium is cheaply a lot.Especially the density of aluminium be copper density 1/3rd less than, even if thus aluminium conductor sectional area brings up to 150% of copper conductor sectional area, the weight of aluminium conductor also only has 45% of copper conductor, this not only makes the tensile strength of aluminium conductor still have some superiority relative to copper conductor, and more make aluminium conductor quality under the condition of same resistance value be only about 50% of copper cash, so aluminium cable has lightweight, that cost is low advantage compared with copper cable.But replace with aluminium coming with some shortcomings again in the practice of copper material, although aluminium density is low, lightweight, but keep the electrical property that automobile cable is constant, cable conductor total sectional area will inevitably be increased, cable is taken up space and becomes large, this gives cable narrow and small and carry out laying installation in the space of complexity and bring very large difficulty, especially in order to improve the pliability of electric wire, so that laying installation, electric wire cable core must take that multifilament is stranded to be formed, monofilament its flexibility thinner of cable core is better, but the quantitative change of cable core monofilament radical is many, space between monofilament becomes large, finally cause again cable thicker, cable takes up space and increases once again.So under guarantee wire electrical property and flexibility situation, the low-density of aluminium and many monofilament cable core all can obviously increase taking up space of electric wire, therefore, how to give full play to aluminum conductor lightweight advantage, reasonable cable core structure, reduces cable core monofilament gap to greatest extent and wire volume becomes matter of utmost importance.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of automotive wiring harnesses aluminum conductor, it effectively can not only alleviate wire weight, reduce wire cost, and under the condition ensureing wire electrical property, effectively can make the optimization of wire volume, be convenient to conductor laying and install.
In order to solve the problems of the technologies described above, automotive wiring harnesses aluminum conductor of the present utility model, comprises cable core, and is coated on the insulating barrier on cable core, and this cable core forms by some aluminium matter monofilament are stranded, the aluminium matter individual filament cross section outside diameter d=0.15mm-0.80mm of described cable core; The resistance per unit length value R of described cable core
