Patent ID: 8146248

Claim:
A method for stopping water from penetrating into a drain wire contained in a shielded wire, comprising the steps of: stripping a necessary length of a sheath of said shielded wire from a front end of said sheath, and leading out a drain wire and an insulated electric wire, wherein the drain wire is in contact with a shielding material made of a metal braid or metal foil and the insulated electric wire serves as a core wire; and inserting said drain wire into a heat shrinkable tube having an obliquely cut portion or a slit portion formed by cut-out at a front end thereof, dripping a water-stopping agent to said obliquely cut portion or said slit portion and placing said water-stopping agent therein, and thereafter heating said heat shrinkable tube for shrinkage, wherein after said drain wire is midway inserted into said heat shrinkable tube, said water-stopping agent is dripped to and held in said obliquely cut portion or said slit portion, and in this state, said heat shrinkable tube is moved to a cut position of said shielded wire.
