[embodiment]
Next, illustrating the embodiment for carrying out an invention by embodiment.These embodiments do not limit the present invention
Range.
The electric wire that there is example 1 shown in table 1 to the composition of example 14 by pulling down molding making, and example 1 is had rated to example 14
Electric wire flexibility.The insulator of institute's live wire uses the Corvic comprising 100 mass parts, 90 mass parts
Trimellitic acid, the stabilizer of 10 mass parts, the filler of 10 mass parts and 5 mass parts fire retardant.
Flexibility
In such a way that radius of curvature becomes 100mm, by the wire bend of predetermined length at U-shaped, and by electrical wire clip one
Between plank, keep one of plank close to another plank, to make electric wire further be bent, until radius of curvature at
Until for 50mm, using repulsive force at this time as the index of flexibility.The close speed of plate is set to 100mm/ minutes, and will be commented
The summation of the contact length of electric wire and plank is set to 300mm when valence starts.
[table 1]
From the example 1 of table 1 to the result of example 5 (2 grades of twisted electric wires) it has been confirmed that being 8.5mm in conductor cross sectional area2Electricity
In line, with the increase of insulation thickness, repulsive force becomes larger, and flexibility reduces.In addition, can be true from the result of example 4 and example 5
Recognize, when insulation thickness is more than 1.4mm, flexibility is greatly reduced.
From the example 6 of table 1 to the result of example 10 (2 grades of twisted electric wires) it has been confirmed that being 14.3mm in conductor cross sectional area2's
In electric wire, with the increase of insulation thickness, repulsive force becomes larger, and flexibility reduces.Here, compared to example 1 to the electric wire of example 5,
Conductor bare wire in example 6 to the electric wire of example 10 is thinner.As a result, compared to example 1 to the electric wire of example 5, the row of example 6 to the electric wire of example 10
Repulsion is smaller, and flexibility is higher.In addition, from the result of example 9 and example 10 it has been confirmed that when insulation thickness is more than 1.4mm, it is soft
It is soft to be greatly reduced.
From the example 11 of table 1 to the result of example 14 (3 grades of twisted electric wires) it has been confirmed that being 21.1mm in conductor cross sectional area2
Electric wire in, with the increase of insulation thickness, repulsive force becomes larger, flexibility reduce.Here, compared to example 6 to the electricity of example 10
The conductor bare wire of line, example 11 to the electric wire of example 14 has roughly the same bare wire line footpath, the sectional area of conductor larger.Phase as a result,
Than the electric wire in example 6 to example 10, the repulsive force of example 11 to the electric wire of example 14 is larger, and flexibility is relatively low.In addition, from example 13 and example 14
Result it has been confirmed that when insulation thickness is more than 1.4mm, flexibility is greatly reduced.
Example 1 to 14 is the evaluation example for making insulation thickness change in the conductor constituted at 3 kinds, but is cut when by conductor
When the larger composition of the area composition smaller with conductor cross sectional area is compared, even if insulation thickness is identical, conductor cross sectional area
Larger composition is also due to the quantitative change of its coating insulator is more, to which repulsive force becomes larger.So, conductor cross sectional area not
With electric wire in, only compare insulation thickness and be difficult to judge flexibility, thus need the identical electric wire of comparison conductor sectional area that
Flexibility around here.
Next, by solid extrusion molding made with example 6 to example 9 have identical composition electric wire (example 15 of table 2 to
Example 18), and have rated " thickness evening ratio " of the example 6 to example 9 and example 15 to the electric wire of example 18.
Table 2
Electric wire for the example 6 to 9 made by lower pulling shaping, even if the relatively thin thickness evening ratio of insulation thickness
It is 75% or more, there is high-durability.On the other hand, for the electric wire of the example 15 to 18 made by solid extrusion molding,
It has been confirmed that even if insulator is thicker, for thickness evening ratio again smaller than 75%, durability is relatively low.In solid extrusion molding, when leading
When body is relatively thin compared with thick or insulation thickness, it was deduced that the quantitative change due to resin is few, thus conductor when molding cannot be completely inhibited
It shakes, conductor shifts from the central shaft of extrusion molding so that thickness evening ratio reduces.
