A high-voltage resistance wire for noise prevention, that is, an ignition cable for blocking radio and television interference radio waves generated by high-frequency oscillation during spark discharge of a spark plug, generally has a configuration as shown in FIG. Reference numeral 1 denotes a core wire made of non-conductive fibers such as glass fibers and polyamide fibers. This core cotton l is covered with ferrite rubber 2, and a metal wire 3 is wound on this in the axial direction to form a wound conductor 4. Form. This winding conductor 4 is covered with a first insulator 6 and a second insulator 8 each having a braid 7 via a strip covering material 5, and an ignition cable 9
It consists of

However, the ignition cable with the above configuration is curved A in Figure 182.
The slope of the electric field intensity (attenuation rate of the electric field intensity) decreases as the temperature rises, and the noise prevention effect deteriorates. The reason for this is that the specific resistance of the ferrite rubber 2 decreases as the temperature rises, and the adjacent metal winding 3
This is thought to be due to a leak phenomenon occurring between a and 3b (see FIG. 1).

Furthermore, the secondary voltage of the ignition cable used to be 15 to 17 KV, but recently it is required to be 20 to 30 KV, which makes the above leakage phenomenon even more severe, making it difficult to achieve a noise prevention effect that satisfies the set value. It became difficult to get caught. Curve B in Figure 2 shows the slope of the electric field strength at 30KV, and Figure 3 is an explanatory diagram of a device for measuring the slope of the electric field strength at 10KV.

In addition, since the ambient temperature of the ignition cable reaches a high temperature of 150-180°C, the end of the ignition cable shown by the arrow P in Figure 4 is burnt out by the high voltage spark, and the spark plug becomes inoperable, causing the engine to burn out. It may cause trouble. The cause of this is electrolytic corrosion due to contact resistance and high voltage between the metal connection terminal 16 and the winding 3, and this electrolytic corrosion is promoted by the rubber or plastic used in the ferrite core (ferrite rubber 2). and winding 3
corrodes at the same time. As for this rubber and plastic,
Conventionally, synthetic rubbers such as chloroprene, nitrile butadiene rubber, styrene butadiene rubber, and ethylene propylene rubber, vinyl chloride resin, and chlorinated polide were used;
n-Zn ferrite with Cu-Zn and Ni-Zn
By blending ferrite-based ferrite, the noise prevention effect is improved, and by using silicone rubber blended with low molecular weight siloxane as the material constituting the ferrite rubber, the heat resistance and chemical resistance of the ignition cable are improved. The inventors have discovered that the noise prevention effect is further improved, and have arrived at the present invention.

00 denier was braided with 7.5 stitches per inch. Next, silicone rubber I (trade name: DX32-057H, east length: 611 m) was coated by extrusion molding as a covering material 8 on the braid 7 to give an outer diameter of 7.0±0.2-. Finally, the insulating materials 6 and 8 are cross-linked simultaneously with the vulcanization to complete the ignition cable 9. That is, the braiding 7 is performed on the insulating material 6 in an uncrosslinked state, so that steam does not come into direct contact with the insulating material 6, there is no risk of moisture intrusion, and the electrical properties, especially the breakdown voltage and dielectric constant, are improved. You can get excellent results.

This is a graph showing the relationship between frequency and electric field strength when changed to KV, but there is a complaint that as the secondary voltage increases, the radio wave prevention effect decreases.

Based on this knowledge, we conducted repeated research on the components of the ferrite core composition in order to improve the insulation between the metal windings, and found that adding low molecular weight siloxane to silicone rubber significantly improved the noise prevention effect. This was confirmed. That is, siloxane has a low molecular weight of 500 to 2,000, and is used in an amount of 2 to 200 parts by weight per 100 parts by weight of silicone rubber.
The amount is in the range of 14 parts by weight, preferably 4 to 12 parts by weight. The addition of this low molecular weight siloxane increases the specific resistance of the ferrite core, and therefore its surface resistance, and provides insulation between the metal winding and the ferrite core. If the amount of this low molecular weight siloxane is less than 2 parts by weight, there will be no insulating effect, and if it exceeds 14 parts by weight, the insulation will improve, but this is unsuitable as it will cause a drop at high frequencies.

That is, as shown in Table 2, ignition cables were made with ferrite cores made of compositions H to T while keeping the amount of mixed ferrite in the silicone rubber constant and varying the amount of low molecular weight siloxane.
