向に亘る接着程度の均一化が困難である。(c) When forming the insulating tape 2 vertically, it is necessary to apply adhesive to the outer periphery of the conductor 1, but at this time, adhesive accumulates on the die etc., and the degree of adhesion in the longitudinal direction is not uniform. is difficult.
(ニ) 液状接着剤をそのまま使用することができな
い。(d) Liquid adhesive cannot be used as is.
(ホ) 製造工程が複雑である。(e) The manufacturing process is complicated.
本考案はこのような点に着目してなされたもの
で、導体と絶縁テープとの間の接着層を絶縁テー
プの貼り合せ部分に対向する一平面に設けること
により前述の問題点を解消しようとするものであ
る。 The present invention was developed with attention to these points, and attempts to solve the above-mentioned problems by providing an adhesive layer between the conductor and the insulating tape on a plane facing the bonded part of the insulating tape. It is something to do.
以下、第３図に示す一実施例に基づいて本考案
を説明する。 The present invention will be explained below based on an embodiment shown in FIG.
第３図において、１は平角導体、２は絶縁紙や

され、この絶縁テープ２端部の積層部３が接着剤
により接合されている。 In Figure 3, 1 is a rectangular conductor, 2 is an insulating tape made of insulating paper or a synthetic resin film such as polyethylene terephthalate film, polyimide resin film, aromatic polyamide resin film, etc., and 4 is an adhesive layer made of an adhesive such as epoxy or polyester. shows. An insulating tape 2 is attached vertically to the outer periphery of the conductor 1, and a laminated portion 3 at the end of the insulating tape 2 is joined with an adhesive.
さらに前記積層部３に対向する導体の一側面と
絶縁テープ２との間に接着層４が設けられた構造
を有する。 Further, it has a structure in which an adhesive layer 4 is provided between one side of the conductor facing the laminated portion 3 and the insulating tape 2.
尚第１〜３図において同一部分は同符号で示し
た。 In addition, in FIGS. 1 to 3, the same parts are indicated by the same symbols.
本考案の平角絶縁電線を製造するには、平角導
体の一平面に接着剤を塗布したのち、この面を絶
縁テープの中央に合わせて平角導体と絶縁テープ
