Line 23 is formed.Second twisted wire 22 is to form twisted 7 of the first twisted wire 21.First twisted wire 21 is by by metal structure
Into more conductor baselines be twisted and form.By being set to the above-mentioned structure being twisted with 3 stages, so that between the conductors
Gap is formed, therefore is able to ensure that flexibility.
For conductor baseline, there is no particular limitation, such as can be made of copper, copper alloy, tin-coated copper, aluminium, aluminium alloy etc..
In addition, the diameter of conductor baseline is preferably smaller than 0.15mm.If using the conductor baseline of thin footpath, baseline is soft in itself, therefore
More soft electric wire can be obtained.The diameter of conductor baseline can be greater than or equal to 0.1mm.
First twisted wire 21 is that conductor baseline is twisted more (first stage is twisted) formed.It is twisted for forming first
The direction of lay and twisted spacing that the radical of the conductor baseline of line 21, first stage are twisted, as long as not damaging the work of the application
With the scope of effect, just there is no particular limitation, if the electric wire of AWG1, AWG1/0, is then preferably set to what is be shown in table 1
Scope.
Second twisted wire 22 is that the first twisted wire 21 is twisted 7 (second stage are twisted) formed.For second stage
Twisted direction of lay and twisted spacing, it is also identical with the situation that the first stage is twisted, as long as not damaging the effect of the application
Just there is no particular limitation for the scope of effect, if the electric wire of AWG1, AWG1/0, is then preferably set to the model being shown in table 1
Enclose.
3rd twisted wire 23 is that the second twisted wire 22 is twisted 7 (phase III are twisted) formed.For the phase III
Twisted direction of lay and twisted spacing, it is also identical with the situation that first, second stage was twisted, as long as not damaging the application's
Just there is no particular limitation for the scope of action effect, if the electric wire of AWG1, AWG1/0, then is preferably set to be shown in table 1
Scope.
【Table 1】
Insulator 3 contains Corvic.As the containing ratio of Corvic, there is no particular limitation, example
Such as it is that 20~80 mass %, preferably 20~58 mass % are preferable.In addition, insulator 3 can be relative to the polychlorostyrene of 100 mass parts
Vinyl, to contain plasticizer less than or equal to 120 mass parts more than or equal to 60 mass parts, preferably with more than or equal to
70 mass parts and contain plasticizer less than or equal to 120 mass parts, further preferably to be less than more than or equal to 70 mass parts
Or contain plasticizer equal to 90 mass parts.Thereby, it is possible to further ensure that the flexibility of insulator 3.As plasticizer, as long as
Commonly used in the plasticizer of insulator of electric wire, just there is no particular limitation, such as can enumerate：Trimellitate (tri trimellitate
(2- ethylhexyls) ester, tri trimellitate nalka base ester, triisononyl trimellitate, triisodecyl trimellitate, trimellitic acid
Three n-octyls etc.), polyester plasticizer.
In addition, in insulator 3, in addition to the foregoing, one kind or two or more filler, fire retardant can also be added, resisted
The various additives such as oxidant, stabilizer, pigment.
Electric wire 1 is to cover to be led by what the twisted wire being twisted with 3 stages was formed using insulator 3 by drawing and forming
Body 2 and manufacture.If manufactured by drawing and forming, form gap between conductor 2 and insulator 3 and can obtain
The excellent flexibility of electric wire 1, is preferred.The thickness of insulator can be set to 0.6mm~3.0mm.
For electric wire 1, power (the hereinafter referred to as pullout forces that conductor 2 is pulled out from insulator 3.) small more than or equal to 2N
In or equal to 20N.Herein, the flexibility of above-mentioned pullout forces and electric wire has correlation, and pullout forces are smaller, and the flexibility of electric wire is got over
It is high.If pullout forces are less than or equal to 20N, become easy to the winding of FERRITE CORE.From the viewpoint of the flexibility of electric wire,
Pullout forces are preferably lower than or equal to 8.5N, pullout forces are further preferably no larger than or equal to 8.3N.On the other hand, if pullout forces are small
In or equal to 2N, although soft, conductor is easily moved relative to insulating layer, and conductor is produced when removing insulator exposes length
Degree can not become the problem of constant such.According to the structure, thick and soft electric wire can be obtained.
The evaluation of above-mentioned pullout forces carries out as follows.First, joint-cutting is formed on the insulator of electric wire, insulator edge is long
Degree direction is mobile and peels off, and makes the electric wire for being divided into the covering portion of length 22mm and the conductor portion of length 20mm.Then, holding is led
Body portion, conductor portion is pulled out with the speed of 200mm/min, and the maximum in during pulling out 22mm is set to pullout forces (N).
It is illustrated by reference pair embodiments of the present invention of Fig. 1, but as the other embodiment of the present invention, can
To be set to the electric wire for possessing such as lower conductor：Formed by being further twisted 12 second twisted wires 22 in the periphery of the 3rd twisted wire 23
The 4th twisted wire form conductor, will more conductor baselines carry out the conductor that is twisted with 4 stages.At this time, for
The direction of lay and twisted spacing that first~fourth stage is twisted, as long as not having the scope of the action effect not damaging the application
There is special restriction, if the electric wire of AWG2/0, AWG3/0, AWG4/0, be then preferably set to the scope being shown in table 2.
