Description of the Related Art In recent years, with the advancement and specialization of electric and electronic equipment, electric wires having special performance have been often required. For example, as a lead wire for a special headlamp of an automobile, an electric wire having the following characteristics is required.

いる。On the other hand, fluororesins and fluoroelastomers have been widely used for coating electric wires because of their excellent heat resistance and electric insulation properties. For example, in Japanese Examined Patent Publication No. 1-37814, the outer circumference of a stranded wire conductor is covered with a fluorine-containing elastomer composition, and a film or cloth-like intermediate layer is interposed between the conductor and the covering layer, and the covering layer is cracked. It is described to prevent the occurrence of.

It is described that an insulator layer made of a fluorine-based rubber composition is formed around a conductor, and a fluorine resin or the like is coated on the insulator layer to improve mechanical properties such as tensile strength.

う。However, when a fluorine-containing elastomer is used alone as a coating layer, even if a tetrafluoroethylene-propylene copolymer, which is said to have the best withstand voltage characteristics, is used, As a result, satisfactory withstand voltage characteristics cannot be obtained, or the wall thickness must be increased in order to improve wear resistance, and the outer diameter of the wire increases.

ではなく、電線の直径が大きくなってしまうという欠点
がある。As described in JP-B-1-37814 and JP-A-3-245412, a film or cloth-like intermediate layer or a fluororesin tape is provided between the conductor and the fluorine-containing elastomer coating layer. With the interposition, it is necessary to wind a large amount of the intermediate layer and the tape in order to obtain sufficient withstand voltage characteristics and sufficient abrasion resistance characteristics, which not only causes problems in productivity and manufacturing cost. However, there is a drawback that the diameter of the electric wire becomes large.

子の接触不良を起こし易い。Further, when a fluororesin is used alone as a coating layer, or when a fluororesin layer is formed on a fluoroelastomer layer as described in JP-A-4-87215, There is a problem that the adhesiveness deteriorates during the molding process for wire connection. Also, with wires using silicone rubber, volatile components such as low molecular weight siloxane are generated while applying a high voltage and adhere to the surface of the lamp, terminals, etc., which may cause fogging of the lamp and poor contact at the terminals. Easy to wake up.

不良を起こし易い。On the other hand, a method of subjecting this fluororesin layer to a corona treatment or a chemical treatment is also known, but none of them has sufficient adhesiveness, or the adhesiveness is remarkably lowered by ultraviolet rays or oil content of the hands. It is poor in handleability and easily causes poor adhesion.

Another object of the present invention is to provide an electric wire that has good adhesiveness and does not generate volatile components.

Then, the present invention has been completed. That is, the present invention is a heat resistant electric wire characterized in that the outer periphery of a conductor is extrusion-coated with a fluororesin and the outermost layer is formed of a fluoroelastomer composition.

好ましく用いられる。In the present invention, the outer circumference of the conductor is extrusion-coated with a fluororesin. Examples of the fluororesin include polyvinylidene fluoride, polytetrafluoroethylene, tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, tetrafluoroethylene-hexafluoropropylene copolymer, polychlorotrifluoroethylene, tetrafluoroethylene-ethylene. Examples thereof include a copolymer and an ethylene chlorotrifluoroethylene copolymer. Among them, because of their excellent electrical properties, polytetrafluoroethylene, tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer,
Tetrafluoroethylene-ethylene copolymer and tetrafluoroethylene-hexafluoropropylene copolymer are preferably used.

ることができる。The thickness of the extrusion-coated fluororesin layer can be arbitrarily changed according to the required withstand voltage characteristics, but DC
To withstand high voltage of 60KV, this thickness is 0.4mm
The above is necessary. If this thickness is less than 0.4 mm, there is a high possibility that dielectric breakdown will occur when DC 60 KV is applied to the electric wire for 1 hour. By extrusion-coating a fluororesin having excellent withstand voltage characteristics, it becomes possible to reduce the thickness of the insulating coating layer and reduce the outer diameter of the electric wire.

In this case, it may be used in a solid form (rubber form). The thickness of the fluorine-containing elastomer layer can be appropriately changed according to the thickness of the fluororesin, but it is usually 0.2 mm or more in the case of a rubber-like elastomer and 0 in the case of a liquid elastomer. It can be thinned to about 0.05 mm.

い。According to the present invention, the outer circumference of the conductor is coated with a fluororesin having excellent heat resistance, withstand voltage characteristics and wear resistance, and the outermost layer is heat resistant and has excellent electric insulation and is made of an epoxy resin or the like. Since it is made of a fluorine-containing elastomer having good adhesiveness with the molding material, it has excellent heat resistance, withstand voltage characteristics and abrasion resistance, and also has good adhesiveness with the molding material. Moreover, since the fluororesin is extrusion coated, an electric wire having a small outer diameter can be obtained without being bulky as in the case of winding a tape, a film, a cloth-like material or the like. Further, since it is covered with a chemically stable fluorine resin or elastomer, no volatile component is generated.
