Background technique
With the increasingly raising of living standard, increasingly increase as the usage amount of the automobile of walking-replacing tool.To guarantee automobile
With line within the voltage of 600V leakproof, need to use specification be 600V resistance to piezoelectric wire.In technical field of automobile parts,
The resistance to piezoelectric wire of 600V is referred to as automobile low pressure line.But it is higher and higher to the quality requirement of automobile low pressure line at present, especially
It is flexibility, wearability, in terms of requirement it is all especially high.
Summary of the invention
In view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of automobile low pressure line, the automobile low pressure lines
With excellent flexibility, wearability and corrosion resistance.
The present invention provides the following technical solutions:
Automobile low pressure line, the core including filled layer and in the filled layer, the core include the first core,
Several second cores on the outside of first core and several third cores on the outside of second core, it is described to fill out
Filling layer includes insulator, and fire retardant is added in the insulator, is successively arranged metal screen layer, band on the outside of the filled layer
And sheath.
Preferably, the material that first core, second core and the third core use is copper.
Preferably, the quantity of first core is 1, and the quantity of second core is 6-8, the third core
Quantity be 11-13.
Preferably, the insulator in the filled layer is PVC.
Preferably, the metal screen layer uses tin plating soft copper silk.
Preferably, the band be high-flame-retardanthalogen-free halogen-free glass fibre belt, the band with a thickness of 0.1-0.3mm.
Preferably, the material that the sheath uses for thermoplastic polyurethane elastomer rubber, the sheath with a thickness of
0.4-1mm。
The beneficial effects of the present invention are:
It is equipped with the core of several rule discharges in automobile low pressure line of the present invention, helps to improve the soft of automobile low pressure line
It is soft, and fire retardant is added in the insulator of filled layer, it can play the role of softening insulator, moreover it is possible to prevent because of automobile
Low pressure line generates heat and causes fire incident；Metal screen layer uses tin plating soft copper silk, and not only shield effectiveness is good, and increases vapour
The flexibility and tensile property of vehicle low pressure line；Band outside metal screen layer is high-flame-retardanthalogen-free halogen-free glass fibre belt, plays protection gold
Belong to the effect of shielded layer and sheath；Sheath uses thermoplastic polyurethane elastomer rubber, and the resistance to of automobile low pressure line can be improved
Mill property and corrosion resistance.
Detailed description of the invention
Attached drawing is used to provide further understanding of the present invention, and constitutes part of specification, with reality of the invention
It applies example to be used to explain the present invention together, not be construed as limiting the invention.In the accompanying drawings:
Fig. 1 is schematic structural view of the invention.
In the figure, it is marked as the 1, first core；2, the second core；3, third core；4, filled layer；5, metal screen layer；6,
Band；7, sheath.
Specific embodiment
As shown in Figure 1, automobile low pressure line, the core including filled layer 4 and in filled layer 4, core include first
Core 1, the third core 3 set on second core 2 in the outside of the first core 1 and set on 2 outside of the second core, the first core 1, the
The material that two cores 2 and third core 3 use is copper, compared with iron material, the conducting electricity very well of copper core, calorific value compared with

Layer 4 includes insulator, is added with fire retardant in insulator, insulator PVC, is successively arranged metal screen layer on the outside of filled layer 4
5, band 6 and sheath 7, metal screen layer 5 use tin plating soft copper silk, and band 6 is high-flame-retardanthalogen-free halogen-free glass fibre belt, the thickness of band 6
For 0.1-0.3mm, the material that sheath 7 uses for thermoplastic polyurethane elastomer rubber, sheath 7 with a thickness of 0.4-1mm.
The setting of the cores of several rule discharges, helps to improve the flexibility of automobile low pressure line in the present invention, and
It is added with fire retardant in the insulator of filled layer 4, can play the role of softening insulator, moreover it is possible to prevent because of automobile low pressure line
It generates heat and causes fire incident；Metal screen layer 5 uses tin plating soft copper silk, and not only shield effectiveness is good, and increases automobile low pressure
With the flexibility and tensile property of line；Band 6 outside metal screen layer 5 is high-flame-retardanthalogen-free halogen-free glass fibre belt, plays protection metal screen
Cover the effect of layer 5 and sheath 7；Sheath 7 uses thermoplastic polyurethane elastomer rubber, and the wear-resisting of automobile low pressure line can be improved
Property and corrosion resistance.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although referring to aforementioned reality
Applying example, invention is explained in detail, for those skilled in the art, still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features.It is all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
