Abstract
The utility model discloses a copper-coated aluminum-alloy conductor cable for an automobile, and the cable comprises a cable core which is formed by the intertwisting of a plurality of insulating cores. The gap of the cable core is provided with a filling layer. A shielding layer wraps the exterior of the cable core, and the outermost layer of the cable core is wrapped by an outer protection layer in a pressing manner. The insulating cores consist of a central conductor and insulating layers wrapping the conductor in the pressing manner. The cable provided by the utility model is good in tensile property, bending property and creep resistance, is light in weight, is low in cost, and the like.
Description
Technical field
The utility model relates to technical field of electric wires and cables, particularly a kind of employing novel cuprum-cladding-aluminium alloy conductor cable for car.
Background technology
Along with the fast development of China's economy, the production and selling amount of automobile is also in rise at full speed.Automotive wire bundle is the important component part of automobile, is that the transmission of automobile is neural, is mainly used in electric energy and the signal transmission of automobile, and each electrical appliance of automobile is effectively worked.At present, countries in the world adopt copper conductor as the transmission conductor of automotive wire bundle mostly, but because the economic development of countries in the world is rapid, have strengthened the consumption of copper resource, cause copper valency in recent years rapidly to rise violently.
The rise at full speed of copper valency brings enormous pressure to the manufacturing enterprise of automotive wire bundle, has also greatly increased the production cost of auto vendor.Along with the competition of automobile industry is more and more fierce, people have carried out continuous research from automotive material, to reduce material cost, to alleviate vehicle weight.If existing a small amount of copper cover aluminum or copper clad aluminum magnesium alloy material of adopting is as automotive wire bundle conductor.
The application of CCAM described in Chinese patent " CN 101017712A " in automotive wire bundle, although adopt this CCAM can reduce material cost and vehicle weight, but because copper clad aluminum magnesium alloy is prone to brittle failure, fail safe is low, and conductor monofilament is difficult to be drawn to very thin, conductor pliability is poor.
In the situation that copper valency constantly rises violently, with aluminium, for copper, be a splendid selection of saving material cost.From conductivity and economy, consider, aluminium is the ideal chose that replaces copper, but the intensity of fine aluminium bar is low, elongation is little, is difficult to be drawn to very thin, and particularly the joint of fine aluminium is prone to oxidation and corrosion, causes security reliability to reduce; And require to have extraordinary pliability and connective stability as automotive wire bundle, so pure aluminum wire is not suitable for and makes automotive wire bundle conductor.
The conventional wire harness of each automobile is to adopt polychloroethylene insulation material mostly now.This insulating material heat resistance is poor, and insulation resistance performance is low, while being used in the high temperature instrument circuit of automobile, because long-term work is under high-temperature situation, has accelerated the aging of insulation, has shortened automobile line useful life, has reduced long-term safety in utilization.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of tensile property, bending property and creep-resistant property good, lightweight, the copper cover aluminum alloy conductor cable for car that cost is low.
The utility model discloses a kind of copper cover aluminum alloy conductor cable for car, comprise cable core, described cable core is by some stranded the forming of insulated wire cores; Cable core gap is provided with packed layer, the outer lapped shielding layer of cable core, and cable core outermost layer extrudes outer jacket; Described insulated wire cores is by the conductor at center and be extruded in conductor external insulation layer and form.
In the utility model, preferably, stranded the forming of copper cover aluminum alloy filaments that described conductor is 0.1mm～1.0mm by diameter.
In the utility model, preferably, described insulating barrier adopts polyvinyl chloride, crosslinked polyethylene, flame retardant polyester thermoplastic elastomer (TPE), fire-retardant PP or perfluoroethylene-propylene material.
In the utility model, preferably, described screen is that copper cover aluminum B alloy wire braid shielded, copper are moored wrapped shielding or self-adhesion polyester/aluminium is moulded the wrapped shielding construction of laminated film.
In the utility model, preferably, described oversheath is that polyvinyl chloride, TPE-U thermoplastic elastomer (TPE) or environment-protective halogen-free low-smoke flame-retardant polyolefin extrude jacket structure.
In the utility model, preferably, the percentage by weight of described aluminum alloy materials composition is: Cu 0.05～0.30%, and Fe 0.25～1.00%, and Mg 0.001～0.22%, Si 0.001～0.15%, Zn 0.001～0.10%, and B 0.001～0.04%, and all the other are Al and inevitable other impurity element, in contained " inevitably other impurity element ", the content of every kind of element is all no more than 0.03%, and the total amount of " inevitably other impurity element " is no more than 0.10%.
The beneficial effects of the utility model are:
(1) copper or tin-coated copper plated aluminium alloy conductor function admirable, can replace copper conductor preferably, and solve the problems such as electrician's fine aluminium conductor is oxidizable, creep-resistant property is poor, and material cost is lower, economic performance is good.
(2) intensity of copper cover aluminum B alloy wire can meet or exceed 180MPa, and percentage elongation is greater than 10%, and conductance can reach 62%IACS～68%IACS, and the joint stable connection of this conductor, be easy to welding, have good connection reliability.
(3) adopt the multicore automotive wire bundle of shielding construction, have good antijamming capability, stable signal transmission is reliable.
(4) adopt crosslinked polyethylene or flame retardant polyester thermoplastic elastomer (TPE) or fire-retardant PP or perfluoroethylene-propylene (F46) insulating material, make automotive line there is good thermal endurance, improved the useful life of automotive line.
