Abstract
The utility model discloses an earthing cable, it has the intensity height, and high frequency transmission performance is good, and is anti -oxidant, anti -corrosion performance is good, long service life, manufacturing cost is lower. An earthing cable which constitutes its characterized in that by a plurality of single line hank systems: the single line is by the sandwich layer and plate and form on the fine copper layer of sandwich layer side, and the sandwich layer adopts stainless steel material to make.
Description
Technical field
This utility model belongs to the technical field of twisted wire, concretely relates to a kind of earthing twisted pair.
Background technology
At present, earthing twisted pair has copper covered steel earthing twisted pair.Copper covered steel earthing twisted pair is twisted by the copper covered steel single line of certain radical
System is formed.Copper covered steel single line includes heart yearn, and the heart yearn is made using low-carbon steel material, and layers of copper is electroplate with heart yearn.It is this to connect
Ground its high-frequency transmission performance of twisted wire is good.But, as heart yearn is made using low-carbon steel material, which is oxidizable, and service life is short.
The content of the invention
The purpose of this utility model is to provide a kind of earthing twisted pair, and which has intensity high, and high-frequency transmission performance is good, antioxygen
Change, corrosion resistance are good, and long service life, manufacturing cost are relatively low.
To solve above-mentioned technical problem, what the purpose of this utility model was realized in：
A kind of earthing twisted pair, which is made up of some single line process, it is characterised in that：Single line is by sandwich layer and is plated in sandwich layer
The pure copper layer composition of side, sandwich layer are made using stainless steel material.
Earthing twisted pair according to claim 1, it is characterised in that：The thickness of pure copper layer is 0.25mm.
Earthing twisted pair according to claim 1, it is characterised in that：The quantity of single line is 7,19 or 37.
This utility model is prominent and beneficial compared to existing technology to be had the technical effect that：
Earthing twisted pair of the present utility model, its single line is using the sandwich layer by made by stainless steel material and is plated in sandwich layer side
Pure copper layer constitute, the high-frequency transmission of stainless steel material is functional, can meet use demand, additionally, stainless steel material is difficult
Oxidation so that the earthing twisted pair long service life.
Description of the drawings
Fig. 1 is the stranded cross-sectional structure schematic diagram of several single lines of the present utility model；
Fig. 2 is the cross-sectional structure schematic diagram of single line of the present utility model.
Specific embodiment
This utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-Fig. 2；
This gives a kind of earthing twisted pair, which is made up of some 1 process of single line, and single line is by sandwich layer 2 and plating
Pure copper layer 3 in sandwich layer side is constituted, and sandwich layer is made using stainless steel material.
Generally, the thickness of pure copper layer 3 is 0.25mm, with good conductive performance.Using the earthing twisted pair of this structure,
Its tensile strength >=100MPa, conductivity >=30%.
In the present embodiment, the quantity of single line is 7 and is formed stranded with core.In another embodiment, the quantity of single line
For 19 or 37 and form stranded with core, and the direction of lay of adjacent layer is contrary.It is using the earthing twisted pair of this structure, stranded
Firmly, the phenomenon of structure stock will not be produced.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection model of the present utility model according to this
Enclose, therefore：All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by protection of the present utility model
Within the scope of.
