Description
【考案の詳細な説明】 （考案の技術分野） 本考案はシールド付き絶縁電線に係る。[Detailed explanation of the idea] (Technical field of invention) The present invention relates to a shielded insulated wire.
（考案の技術的背景と考案の目的）
従来、電線のシールド層としては、編組、金属
メツキ、横巻き、導電性樹脂被覆等各種の形態が
採用されている。(Technical background of the invention and purpose of the invention) Conventionally, various forms such as braiding, metal plating, horizontal wrapping, and conductive resin coating have been adopted as shield layers for electric wires.
本考案はこのうち特に、耐熱性の高い絶縁被覆
例えばテトラフロロエチレン樹脂等の被覆を有す
る電線の、端末処理の容易なシールド構造に係
る。 The present invention particularly relates to a shield structure for easily terminal-processing an electric wire having a highly heat-resistant insulation coating, such as a coating made of tetrafluoroethylene resin.
（考案の構成） 以下、本考案を図面によつて説明する。(Structure of the idea) The present invention will be explained below with reference to the drawings.
第１図は本考案の絶縁電線の実施例横断面図で
ある。 FIG. 1 is a cross-sectional view of an embodiment of the insulated wire of the present invention.
図において、中心導体１は銅の単線あるいはよ
り線から成る。その外周は耐熱絶縁被覆２例えば
テトラフロロエチレン絶縁被覆である。 In the figure, the central conductor 1 consists of a single or stranded copper wire. Its outer periphery is covered with a heat-resistant insulation coating 2, such as a tetrafluoroethylene insulation coating.
この絶縁被覆２の外周には、錫メツキ銅線等の

る低融点金属層４が形成されている。 Three metal wires 3 such as tin-plated copper wires are wound around the outer periphery of the insulating coating 2 at relatively long pitches in the longitudinal direction of the cable. And this metal wire 3
A low melting point metal layer 4 made of solder or the like is formed around the outer periphery of the insulating coating 2 with the core being the core.
さらに、最外層にはポリエチレン等のシース５

is covered. Such an insulated wire is manufactured using an apparatus as shown in FIG.

で、その表面張力によつて金属線を芯として電線
外周に均一に被覆される。このとき、低融点金属
４の融点は耐熱絶縁被覆２の軟化流動温度よりも
低いことが必要である。 In the figure, a heat-resistant insulated electric wire 7 wound around a supply drum 6 has a metal wire wound around its outer circumference by a metal wire winding machine 8, and then a solder shield layer is formed in a molten solder bath 9. . Since the metal wire is wound around the wire at appropriate intervals, the solder is uniformly coated around the wire with the metal wire as the core due to its surface tension. At this time, the melting point of the low melting point metal 4 needs to be lower than the softening flow temperature of the heat-resistant insulating coating 2.
また、金属線３は低融点金属４と親和性の良い
メツキ等の被覆が施されていることが望ましい。 Further, it is desirable that the metal wire 3 is coated with a coating such as plating that has good affinity with the low melting point metal 4.
なお、ハンダの融点は200℃以下で、テトラク
ロロエチレンはそれ以上でも形状を保持すること
はいうまでもない。 Note that the melting point of solder is 200°C or lower, and it goes without saying that tetrachlorethylene retains its shape even at temperatures higher than that.
（考案の効果）
以上、述べた本考案のシールド付き絶縁電線は
次のような作用効果を有している。(Effects of the invention) The shielded insulated wire of the invention described above has the following effects.
(イ) シールド層の形成がきわめて容易であり、製
造コストを低減できる。(a) Formation of the shield layer is extremely easy and manufacturing costs can be reduced.
(ロ) 端末処理の際には金属線がドレンワイヤとし
て使用でき、接続作業が簡単である。(b) The metal wire can be used as a drain wire during terminal processing, making connection work easy.
(ハ) 導電性樹脂や編組によるものと比較して導電
率が大きく、しやへい面積が広くなつており、
しやへい効果が高い。(c) Compared to those made of conductive resin or braid, the conductivity is higher and the flexible area is wider.
Highly soothing effect.
