【考案の詳細な説明】 〔考案の目的〕 （産業上の利用分野） 本考案は、移動用車輌における点火コードとして用いら
れる捲線式雑音防止高圧抵抗電線に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to a wire-wound noise-preventing high-voltage resistance wire used as an ignition cord in a mobile vehicle.

ものや（特開昭54−106884号）、アラミッド繊維を用い
たもの（特開昭58−169708号）、更には上記両者の混紡
によるもの（実開昭61−14424）が使用されている。(Prior Art) A wound-type ignition cord used in an automobile or the like generally has a core layer formed by rubber extrusion coating on a tension member, and a resistance wire is wound around the outer periphery of the core layer at a predetermined pitch.
It is made by covering it with an insulator such as rubber,
Examples of the tension members include those using glass fibers (Japanese Patent Laid-Open No. 54-106884), those using aramid fibers (Japanese Patent Laid-Open No. 58-169708), and those obtained by blending the above two (actually developed). Sho 61-14424) is used.

より発生する内部繊維間摩耗（アラミド繊維間の摩耗）
には比較的弱い面がある。又、吸湿による強度低下があ
るため、製造使用前には乾燥や、疎水化処理等の前工程
を必要とする欠点があった。(Problems to be solved by the invention) In the first place, the tension member is intended to be held during use or manufacturing so as not to be broken due to high tension such as bending, but on the other hand, the electrostatic characteristic which is a typical characteristic of the ignition cord is In consideration of capacity and breakdown voltage, the thinner the tension member is, the more ideal. However, the strength of glass fiber is low and therefore it cannot be made too thin, and aramid fiber has excellent tensile strength, but internal fiber-to-fiber wear (wear between aramid fibers) caused by repeated bending, vibration, etc.
Has a relatively weak side. Further, since the strength is lowered due to moisture absorption, there is a drawback that a pre-process such as drying and hydrophobization treatment is required before production and use.
本考案は上記した従来技術の欠点に着目し、テンション

を意図する。The present invention focuses on the above-mentioned drawbacks of the prior art and intends to strengthen the strength of the tension member while preventing the tension member from being enlarged.
（課題を解決するための手段） 本考案は、テンションメンバーにポリアリレート繊維を

雑音防止高圧抵抗電線として完成される。(Embodiment) The present invention will be shown below together with illustrated embodiments. FIG. 1 shows the structure of an embodiment of the present invention, in which the tension member 1
Is made of polyarylate, and the extrusion coating layer 2 is formed thereon as an insulating layer to form a core layer. A rubber composition in which ferrite powder or the like is mixed is used for the insulating layer. A metal resistance wire 3, for example, a nichrome wire is wound around the outer periphery of the core layer with a certain pitch so as not to contact each other, and an insulating layer 4, a braid layer 5, and a sheath layer 6 are formed on the metal resistance wire 3. The insulation cord 7 is covered, and the ignition cord 8 is completed as a winding type noise-preventing high-voltage resistance electric wire.
素材の変更によって期待される効果は、第１表に示すよ
うに１デニール当たりの引張強度は、従来の素材である
ポリアラミドやガラス繊維と比較して1.2倍から2.7倍に
向上する。As shown in Table 1, the expected effect of changing the material is that the tensile strength per denier is 1.2 to 2.7 times that of conventional materials such as polyaramid and glass fiber.
テンションメンバーは極微細な繊維を撚り合わせて使用

る。この特性の顕著な向上は第２表に示す繊維間摩耗特
性に見られるものであって、ポリアラミドと比較して24
倍まで強化されている。 Since the tension member is used by twisting extremely fine fibers, interfiber wear occurs due to bending or vibration. This remarkable improvement in properties is seen in the interfiber wear properties shown in Table 2, which is 24% higher than that of polyaramid.
Has been reinforced up to twice.
又比重においても従来のポリアラミド繊維と同等であ
り、軽量性は維持されている。 Moreover, the specific gravity is the same as that of the conventional polyaramid fiber, and the lightness is maintained.
このように優れた素材を構成材料として使用することに
よって、耐屈曲性、耐振動性に優れた軽量の点火コード
を得ることができる。By using such an excellent material as a constituent material, it is possible to obtain a lightweight ignition cord having excellent bending resistance and vibration resistance.

できる。On the other hand, regarding the environmental resistance characteristics, as shown in the tensile strength after wet heat treatment in Table 3, in the case of polyarylate, the deterioration of the characteristics before and after the test by this environmental test is compared with the characteristics shown in Table 1. As can be seen, it is only 15%, and a significant improvement in environmental resistance can be seen when compared to the 55% performance degradation of conventional polyaramids under the same conditions.
従って製造工程でも特別の前処理工程を必要としない。
又製造設備的にも従来の設備をそのまま流用できるし、
製造時に必要とされる引張強度に関してもポリアラミド
繊維と同等であるので、新製品への切り替えへの抵抗は
全くない。 Therefore, the manufacturing process does not require any special pretreatment process.
In terms of manufacturing equipment, conventional equipment can be used as is,
The tensile strength required at the time of manufacture is also equivalent to that of polyaramid fiber, so there is no resistance to switching to a new product.

期待できる。As shown in FIG. 2, the tension member 1 has a structure in which polyarylate fibers having a desired thickness are twisted into one,
As in the second embodiment (FIG. 3), a plurality of polyarylate fiber bundles twisted into one may be twisted together to form one tension member 1A. The material for the tension member is polyarylate fiber as in the first embodiment, and the effect can be expected to be exactly the same as in the first embodiment.

優れた点火コードを提供できる。As is clear from the above explanation, by using polyarylate as a tension member in ignition cords for mobile vehicles such as automobiles, vibration resistance and bending resistance are particularly excellent, and tensile strength and light weight are also excellent. Also has the same characteristics as those using conventional aramid fibers, and does not require a tension member drying step during manufacturing,
Moreover, it is possible to provide an ignition cord excellent in strength retention without particularly changing the conventional manufacturing equipment.
