【考案の詳細な説明】
本考案は長手状の被着体のまわりに被覆される割型熱収
縮チューブの接合部に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a split heat shrink tube joint that is wrapped around a longitudinal adherend.
熱収縮チューブは熱による復元性質を利用してガス、水
道、パイプライン等の接続部保護あるいはケーブル接続
部等の保護に使われている。Heat-shrinkable tubes are used to protect connections in gas, water, pipelines, etc., as well as cable connections, by making use of their ability to recover due to heat.
ががる場合チューブの長さ方向に開きうる割型チューブ
を使用すると被着体への装着が容易である。If the tube comes loose, it is easier to attach it to the adherend by using a split tube that can be opened in the length direction of the tube.
特に接続を既に完了した被覆体の場合は割型チューブで
ないと実際上使用できない。Particularly in the case of a sheath that has already been connected, it cannot actually be used unless it is a split tube.
ところが、従来の割型チューブは割型接合部の接合力が
十分なものがなく、加熱収縮時に接合部ではずれたり、
接合部の直下で被着体との間に間隙ができたりするとい
う欠点があった。However, conventional split tubes do not have sufficient bonding force at the split joint, and may come off at the joint during heat shrinkage.
There is a drawback that a gap may be formed between the bonded material and the adherend directly below the joint.
本考案はこれらの欠点を除去しうるもので熱収縮チュー

徴とするものである。The present invention is capable of eliminating these drawbacks, and includes a pair of elongated plate-shaped gassho portions provided outside the split cut portion of the heat-shrinkable tube, and a large number of through holes provided in the gassho portions of one pair from the outside. A reinforcing plate bent in an L shape is placed along the boundary between the palm part and the cylindrical part of the heat-shrinkable tube, and an eyelet-shaped metal fitting is inserted and fixed into the through-hole. This is a characteristic feature.
以下本考案を図面の実施例をもとに説明する。The present invention will be explained below based on the embodiments shown in the drawings.

接合できないというような問題もある。It is also possible to insert and fix an eyelet-shaped metal fitting into the through hole using a split heat shrink tube like this, and then heat-shrink it. There is also the problem that it digs into the palms of the hands and prevents the palms from joining completely.
そこでこのような合掌部のへたりを防止するため、合掌
部の外側へ両側から第２図の如き当て板を当てがい、そ
の当て板の外側から従来のハトメ状金具を使って接合固
定する方法を案出した。Therefore, in order to prevent this kind of sagging of the palms in prayer, a patch plate as shown in Figure 2 is applied from both sides to the outside of the palms in prayer, and a conventional eyelet-shaped metal fitting is used to join and fix it from the outside of the patch. devised.

又合掌部に当接する側２０は合掌部が長手方向に熱収縮
チューブの軸と切開部でできる面内で曲がりやすいよう
に数多くのスリット２３が設けられる。Further, on the side 20 that comes into contact with the palm-to-palm part, a number of slits 23 are provided so that the palm-to-palm part can easily bend in the longitudinal direction within a plane formed by the axis of the heat-shrinkable tube and the incision.
Ｌ型の当て板は割型収縮チューブの合掌部外側と合掌部
と円筒部の境界線にそって当接されるが該当て板の円筒
部に接する側２１には前記のスリット状のものはない。The L-shaped backing plate is brought into contact with the outside of the joint part of the split shrink tube and along the boundary line between the joint part and the cylindrical part, but the above-mentioned slit-shaped plate is placed on the side 21 of the plate that contacts the cylindrical part. do not have.
なおこの当て板は金属板あるいは硬質のプラスチック板
