Abstract:
1. A method for water-stopping an earthing electric wire, comprising the steps of: preparing at least one earthing electric wire for connecting a circuit mounted on a vehicle with the earth having a conductor and a coating material on an outer side of the conductor, the coating material extending along substantially an entire length of the conductor except for an end portion of the conductor that is free of the coating material, feeding a water-stopping agent having a flowability to one terminal of the at least one earthing electric wire at a location adjacent to an end of the coating material; sucking an air in an inner side of the coating material of the at least one earthing electric wire, during or after the feed of the water-stopping agent, from the other terminal of the at least one earthing electric wire; and reducing a pressure of the inner side of the coating material of the at least one earthing electric wire by the sucking step so that the water-stopping agent penetrates into the inner side of the coating material, the water-stopping agent thereby contacting the conductor and being located between the conductor and the coating material only at a terminal portion of the at least one earthing electric wire, thus forming a water-stopping portion at the terminal portion, wherein part of the length of the end portion of the conductor is free of any water-stopping agent.
