Description
Technical field
Cable correlative technology field is the utility model is related to, specifically, is related to a kind of small line footpath enamel-cover painted again and is twisted
Line, to substitute traditional at present enamel-cover twisted wire or silk bag enamel-cover twisted wire, meet answering on high-frequency wireless signals transmission equipment
Use demand.
Background technology
Common enamel-cover twisted wire is twisted by the enamel-cover single line of more than two, and it is improved compared with enamel-cover single line
Surface area, and Distribution of Magnetic Field is more uniform, and kelvin effect is small, high frequency equivalent resistance is relatively low, and vortex is small, and temperature rise is low, and transmission is special
Property is good, and anti-corona ability and high frequency voltage bearing capacity are stronger, therefore widely apply to common electric machine, transformer, electrical equipment, instrument
The making of winding, coil in table.
Wrapped one layer of empire silk (such as dacron thread), can lift the pressure-resistant of twisted wire at double outside traditional enamel-cover twisted wire
Level, this line are referred to as silk bag enamel-cover twisted wire.Silk bag enamel-cover twisted wire is due to its pressure-resistant advantage, in recent years in electronic transformer
Device/inductance industry is widely used.But silk bag enamel-cover twisted wire production cost is of a relatively high, and its pliability index is not so good as enamel-cover
Twisted wire.
In addition, in the small-power such as transmission of wireless signals equipment/high-frequency field application, because working frequency is higher, it is
The voltge surge caused by HF switch is resisted, on the one hand its pair twist zygonema insulating requirements is higher, on the other hand due to wireless
Signal transmission apparatus power is relatively low, and its internal coiling wire general requirements used is smaller, complete external diameter generally 1mm with
Under, traditional silk bag enamel-cover twisted wire is just difficult to meet use demand.
Utility model content
The utility model is of a relatively high for cost existing for existing silk bag enamel-cover twisted wire, and pliability is insufficient, external diameter
Size is larger, it is difficult to the problem of meeting to apply in the small-power such as transmission of wireless signals equipment/high-frequency field, there is provided a kind of multiple paint
The small line footpath enamel-cover twisted wire of formula.
Technical problems to be solved needed for the utility model, it can be achieved through the following technical solutions：
It is a kind of to paint the small line footpath enamel-cover twisted wire of formula, including the enamel-cover twisted wire matrix that more enamel-cover single lines are twisted again,
It is characterized in that：The enamel-cover twisted wire matrix is wrapped with insulating lacquer layer, and insulating lacquer layer is filled between the enamel-cover single line
Gap, and form cross section in the outside of enamel-cover twisted wire matrix and be less than for circular outline, the external diameter of the outline
1mm。
In the utility model, the external diameter of the enamel-cover twisted wire matrix is D, and the external diameter of the outline is more than 1.1D.
In the utility model, the insulating lacquer layer is polyurethane insulating enamelled coating.
In the utility model, the insulating lacquer layer is polyurethane insulating varnish and coloured enamel compound inslation enamelled coating.
In the utility model, the external diameter of the enamel-cover single line is less than 0.08mm, and the enamel-cover twisted wire matrix is by 50 to 100
Root enamel-cover single line is twisted.
The enamel-cover twisted wire matrix is twisted using clock-wise fashion.
The lay of the enamel-cover twisted wire matrix is 3cm.
The enamel-cover single line is polyurethane paint enamel-cover single line.
It is of the present utility model to paint the small line footpath enamel-cover twisted wire of formula again, to enamel-cover twisted wire by way of secondary coating insulation
Matrix is wrapped up so that more than the line high pressure 700V of twisted wire, compared with traditional silk bag enamel-cover twisted wire, it is outside absolutely
Edge layer tightness will get well, and can reduce twisted wire pin hole quantity.This twisted wire surface smoothness also has substantially than traditional silk-covered wire
Improve, greatly facilitate the process with twisted wire coiling inductance, transformer, secondly, secondary coating insulated paint is due to that will not produce
Mechanical stress as bag dacron thread, its flexibility are good so that the transformation body that the utility model enamel-cover twisted wire is wound up
Product is more compact, and finally, using the small line footpath enamel-cover twisted wire of secondary coating insulated paint, its production efficiency will also be far above bag terylene
The production efficiency of silk.
