MANUFACTURING METHOD OF ELECTRIC WIRE WITH HEAT-SHRINKABLE TUBING

PROBLEM TO BE SOLVED: To provide a technique for easily improving a water cut-off performance of a heat-shrinkable tubing.SOLUTION: In an electric wire with a terminal 10, an exposure core wire part 14a exposed to one end of an electric wire 12 includes a connection part 11 jointed to a support surface 200S of a plate-like terminal 20. The electric wire with the terminal is inserted 10 to a heat-shrinkable tubing 30B. In the heat-shrinkable tubing 30B, a thermoplastic adhesive layer 32L is formed on an inner peripheral surface, and an expansion part 320 of a thermoplastic adhesive agent in which a base end part 322 is communicated to the thermoplastic adhesive layer 32L is formed. The heat-shrinkable tubing 30B is heated and contracted in a state where the expansion part 320 is distributed on the side of the support surface 200S of the terminal 20.SELECTED DRAWING: Figure 3 【課題】熱収縮チューブの止水性を容易に向上する技術を提供する。【解決手段】電線１２の一端に露出した露出芯線部１４ａが、板状の端子２０の支面２００Ｓに接合する接続部１１を有する端子付電線１０が、熱収縮チューブ３０Ｂに挿入される。熱収縮チューブ３０Ｂは、内周面に熱可塑性接着剤層３２Ｌが形成されており、かつ、基端部３２２が熱可塑性接着剤層３２Ｌに連なる熱可塑性接着剤の張出部分３２０が形成されている。張出部３２０が端子２０の支面２００Ｓの側に配された状態で、熱収縮チューブ３０Ｂを加熱して収縮させる。【選択図】図３
