MANUFACTURING METHOD OF THERMAL CONTRACTION CAP, THERMAL CONTRACTION CAP AND WIRE WITH THERMAL CONTRACTION CAP

摘要

PROBLEM TO BE SOLVED: To provide a technique capable of restraining outflow of the plug of a thermal contraction cap.;SOLUTION: A manufacturing method of thermal contraction cap includes following steps (a) and (b). The step (a) is a step of placing a capsule 32, containing an inclusion body 34, and a covering 36 formed of a material collapsing by heating and wrapping the inclusion body 34, in one end 22 of a heat-shrinkable tubing 21 having both open ends. The step (b) is a step of forming a plug 30 for sealing the opening of the one end 22 by heating the one end 22, thereby contracting the one end 22 and hardening the inclusion body 34, while collapsing the covering 36.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
