ELECTRIC CABLE END PROCESSING METHOD AND ELECTRIC CABLE END STRUCTURE WITH SOLDER COATING AND SHEATH PROTECTION

摘要

An end processing method for processing an end of an electric cable (11) including a conductor (12) made from aluminum or an aluminum alloy and a sheath (13) covering the conductor (12) is provided. The end processing method includes steps of: removing an end portion of the sheath (13) to expose an end portion (16) of the conductor (12); immersing the a part of the exposed end portion (16) of the conductor (12) into molten solder to coat the immersed part of the exposed end portion of the conductor (12) with solder (14); providing a heat shrinkable tube (15) through which the conductor (12) is inserted so that a remaining portion (14a) of the conductor (12) which is not coated with solder (14) is covered by the heat shrinkable tube (15); and shrinking the heat shrinkable tube (15) by heating the heat shrinkable tube (15) so as to be close contact with the conductor (12) and the sheath (13).
