Abstract: The present invention seeks to enable a band-shaped metal wire member to be stably accommodated within a die. A die is prepared that includes a bottom die provided with a depression and a top die provided with a projection that can be arranged within the depression so as to close off a space above the depression. An inner surface of the depression includes a central die surface formed at a width-direction center of a base of the depression and a pair of curved guide die surfaces provided continuous with two sides of the central die surface and curved so as to project outward. The central die surface is formed as a flat surface or as a surface that curves more gently than the pair of curved guide die surfaces. A bonding process portion of a band-shaped metal wire member is folded in two and arranged within the depression.

Abstract: A conductive member production method is performed with use of a die that includes a first die and a second die. The first die includes a protruding portion having a recession-shaped depression formed in a leading end surface, the depression including a molding surface that is inclined so as to gradually extend toward the leading end surface side while extending laterally from the depression. The second die includes a recessed portion into which the protruding portion can be inserted. The method includes a heating step of heating a weld portion formation region that is a portion, with respect to an extending direction, of a conductive member constituted by multiple metal strands, and a pressing step in which the heated weld portion formation region is sandwiched between and pressed by the protruding portion of the first die and the recessed portion of the second die.

Abstract: A terminal is crimped to a portion where a plurality of metal strands are welded. A conductive member is configured by a plurality of coated metal wires provided with a plurality of metal strands and with an electrically conductive sheath covering a circumference of each of the plurality of metal strands. The conductive member includes a welded portion, in which at least a portion in an extension direction of the plurality of coated metal wires is welded, and the welded portion includes an outer layer that is formed on an outer circumference side by welding the plurality of coated metal wires together, and at least a portion of the plurality of coated metal wires on an inner side of the outer layer is capable of untwining due to crimping a terminal.

Abstract: The present invention seeks to provide a technology that crimps a terminal and a conductive member configured by a plurality of metal strands together in a more stable state. A method of manufacturing a terminal-equipped conductive member is performed using a die, which includes a first die having a projection and a second die, the second die having a depression into which the projection can be inserted, and having a pair of side wall surfaces of the depression which include a first molding surface inclined along an inner surface of a pair of crimping tabs of a pre-crimping terminal, the method including a welding step of arranging in the die a welded portion formation region, which is a region on an extension direction portion of a conductive member, and welding the plurality of metal strands together; and a crimping step of crimping the welded portion and the terminal together.
