る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for attaching a heat-shrinkable tube, and more particularly, to a method for attaching a heat-shrinkable tube to the terminal end or connection portion of a rubber-plastic insulated cable, for example. .
熱収縮性チユーブは、その取り扱いが容易なこ
とからたとえばゴム・プラスチツク絶縁ケーブル
の終端部あるいは接続部などの外装として盛んに
用いられるようになつて来たことは知るところで
ある。 It is well known that heat-shrinkable tubes have come to be widely used, for example, as sheathing for the terminations or connections of rubber-plastic insulated cables because of their ease of handling.
ところが、熱収縮性チユーブを収縮させるに
は、これを収縮開始温度まで温度上昇させる必要

全となり易く、従つて、当該個所を通路として浸
水などを起し易いといつた問題があつた。 However, when shrinking the heat-shrinkable tube in this manner, it is extremely difficult to heat the entire heat-shrinkable tube uniformly, and local heating is inevitably performed. For this reason, it was easy to create unevenness on the surface of the heat-shrinkable tube. Of course, in such a case, not only will the outer tube deteriorate, but the object (rubber,
There has been a problem in that the adhesion between the heat-shrinkable tube and the terminal end or connection part of the plastic insulated cable tends to be incomplete, and therefore water can easily enter the area using this area as a passage.
更には、あぶり過ぎによつて熱収縮チユーブに
損傷を与えてしまい易いといつた問題もあつた。 Furthermore, there was also the problem that the heat shrinkable tube was easily damaged by overheating.
本発明は、上記の点に鑑みて為されたものであ
つて、その目的は上述の難点を一掃し得る熱収縮
性チユーブの取付工法を提供することにある。 The present invention has been made in view of the above points, and its purpose is to provide a method for attaching a heat-shrinkable tube that can eliminate the above-mentioned difficulties.

それ自身の中央部から両端に向つて順次加熱収縮
させる点にある。 That is, the gist of the present invention is to arbitrarily cover the circumference of an object with a predetermined heat-shrinkable tube, and further cover the circumference of the heat-shrinkable tube with a wrapped layer of heat-resistant plastic tape. The heat-shrinkable tube is covered with a cylindrical body provided with a heater, with the central part being denser and the heaters becoming coarser toward both ends.Then, the heater is activated to make the heat-shrinkable tube The plastic tape is heated and shrunk sequentially from the center to both ends through the wrapped layer of plastic tape.

It can be used not only for the end of a plastic insulated cable or for the cable itself, but also for anything else to which a heat-shrinkable tube is attached.
さて、本実施例の説明に入ることとする。 Now, let us begin to explain this embodiment.
まず、ゴム・プラスチツク絶縁ケーブル１，

A heat-shrinkable tube (for example, an electron beam irradiated polyethylene tube) 3 is placed over the circumference of the connecting portion 1' (detailed explanation is omitted) 2, and a heat-resistant plastic tape is further applied to the surface of the heat-shrinkable tube 3. (For example, tetrafluoroethylene tape) 4 is wrapped in at least two layers.

身の中央部分から順次両端へ向つて収縮させる。 In this state, a halved metal pipe 6 is placed on the outside of the heater wire 5, which is wrapped tightly around the heater wire 5 in the center and loosely toward both ends. A heat-resistant treatment layer (for example, a layer wrapped with glass fiber tape) 7, 7' is provided, and the heat-shrinkable tube 3 is raised to a predetermined temperature by means of a heating wire 5 via a layer 4 wrapped with heat-resistant plastic tape. Then, the tube 3 is contracted sequentially from its central portion toward both ends.

善される。 According to the heat-shrinkable tube installation method of this embodiment, which is carried out in this manner, the heat-shrinkable tube is first heated through the wrapped layer of heat-resistant plastic tape. This greatly improves what was done when the tube was damaged.

ことはもとより、熱収縮性チユーブと対象物相互
間においては完全なる密着状態を作り得る。 Moreover, the heating of the heat-shrinkable tube is not just done randomly over the entire tube as in the past, but is heated densely in the center of the tube and becomes more coarse toward both ends. By using a halved metal pipe with a heating wire wrapped around it, the heat-shrinkable tube is contracted from the center of the tube sequentially toward both ends, so the shrinkage of the heat-shrinkable tube can be done quickly and accurately. Therefore, not only can a good-looking finish be expected, but also complete adhesion can be created between the heat-shrinkable tube and the object.

わめて大きい。 As described above, the heat-shrinkable tube installation method of the present invention can eliminate the problems that were considered to be difficult in previous methods, and has extremely great practical value.
