本発明はケーブルシースなどの接続に使用する
背割形熱収縮チユーブの収縮方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for shrinking a split-back heat shrink tube used for connecting cable sheaths and the like.
従来よりケーブルシースの補修、ケーブルシー
スの接続などに背割形熱収縮が使用されている。 Split type heat shrinking has traditionally been used for repairing cable sheaths, connecting cable sheaths, etc.
ケーブルシースの補修として、ケーブルシース
にキズが付いた場合、その部分のシースを除去
し、熱収縮チユーブを被せること、また、ケーブ
ルシース接続として、ケーブル線心を接続し、そ
の上部およびシース上に熱収縮チユーブを被せて
いる。しかし熱収縮チユーブを使用する個所が、
ケーブルシースのような形状が均一で固い部分で
あれば熱収縮チユーブもなじみ易いが、ケーブル
線心部のような凹凸があつて固くない部分がある
と、熱収縮チユーブに均等な収縮力が加わらない
部分がでてくる欠点があつた。 To repair a cable sheath, if the cable sheath is scratched, remove the sheath in that area and cover it with a heat-shrinkable tube.Also, to connect the cable sheath, connect the cable core and place it on top and on the sheath. It is covered with a heat shrink tube. However, where heat shrink tubes are used,
The heat-shrinkable tube will fit easily if it has a uniformly shaped and hard part, such as a cable sheath, but if there is a part that is uneven and not hard, such as the core of the cable, the heat-shrinkable tube will not be able to apply even shrinkage force. There was a drawback that some parts were missing.
しかも、背割形熱収縮チユーブは、その背割り
の合せ目をいかに加熱収縮させ、確実な水密性を
確保することが大きなポイントとなる。 Moreover, the key point for a split-back heat-shrinkable tube is how to heat-shrink the seam of the back splits to ensure reliable watertightness.
更には、背割部全長がＣ形の金属チヤンネルで
継がれているため、確実な取付状態の有無を目視
でチエツクすることが不可能であつた。 Furthermore, since the entire length of the back split portion is joined by a C-shaped metal channel, it has been impossible to visually check whether or not the attachment is secure.
そのため、その背割部の合せ目をいかに確実に
加熱収縮をさせ、水密性を確保することが問題で
あつた。 Therefore, the problem was how to reliably heat-shrink the seams of the back splits and ensure watertightness.
本発明の目的は、チユーブの背割部の下側の凹
凸、軟かい部分を解消し、背割部の水密性を向上
させることができる背割形熱収縮チユーブの収縮
方法を提供することにある。 An object of the present invention is to provide a method for shrinking a split-back type heat-shrinkable tube that can eliminate unevenness and soft parts on the lower side of the split-back part of the tube and improve the watertightness of the split-back part. be.
すなわち本発明の要旨は、背割形熱収縮チユー
ブの背割部の下側に当板を取付け、チユーブを加
熱収縮する際、背割部の収縮力がケーブル内に均
等に加わるようにして、背割部の水密性を確保す
ることにある。 That is, the gist of the present invention is to attach a backing plate to the lower side of the split back part of a split back type heat-shrinkable tube, so that when the tube is heat-shrinked, the shrinkage force of the split back part is evenly applied to the inside of the cable. The purpose is to ensure watertightness of the back split.
上記において当板の材質としてはアルミニウ
ム、銅、黄銅等の金属、あるいはプラスチツクが
使用できる。 In the above, the material of the plate may be metal such as aluminum, copper, brass, or plastic.
本発明の一実施例を図面に基づいて説明する。
第１図はケーブル６の接続部５に熱収縮チユーブ

取付けることになり、背割部の水密性を確保する
ことができる。 An embodiment of the present invention will be described based on the drawings.
Figure 1 shows a cable 6 with a heat-shrinkable tube 1 placed over the connecting part 5. Before heat-shrinking, a patch plate 3 is placed on the part that will become the back-split part 2 of the split-back heat-shrinkable tube 1 for cable sheath connection. It was attached with tape wrapping 4, and then heated from the outside to cause heat shrinkage. In this case, the part where the backing plate 3 is attached is less uneven than the cable core 5 and can be corrected.
The entire length of the back split portion of the heat-shrinkable tube 1 is attached with uniform shrinkage force, and the watertightness of the back split portion can be ensured.
第２図はＡ―Ｂ断面を示すもので、背割部２の
外部はＣ形の金属チヤンネル７で継がれている。 FIG. 2 shows a cross section taken along line AB, and the outside of the back split portion 2 is joined by a C-shaped metal channel 7.
以上説明した通り本発明方法は、熱収縮チユー

ユーブを加熱収縮する際、背割部全長に亘り均等

保できる。 As explained above, in the method of the present invention, by attaching a backing plate under the split back of a heat-shrinkable tube, the backing plate is harder than the cable core and has less unevenness, so when the tube is heat-shrinked, the entire length of the back split is Since uniform contraction force is applied over the entire length of the back split, watertightness can be ensured over the entire length of the back split.
尚、当板はケーブル部の形状に合せて容易に加
工ができ、ケーブルシース補修等の場合、ケーブ
ルを切断せずに、取付けることができる。 The plate can be easily processed to match the shape of the cable section, and can be attached without cutting the cable when repairing the cable sheath.
また、当板は筒形に較べて極めて安価に供給す
ることができる。 Furthermore, the backing plate can be supplied at a much lower cost than the cylindrical one.
