Abstract: An electric line wiring structure of a plug includes a plurality of terminals to be inserted into a power supply and electric lines connected to the terminals. The plurality of terminals protrudes on a front side of a plug main body. The electric lines are connected on a rear side of the plug main body. An electric line wiring section for wiring the electric lines connected to the terminals is provided in the plug main body. An electric line holding section for holding the electric lines in a deformed state is provided on a wiring path for wiring the electric lines, which are set in the electric line wiring section. The electric lines are deformed in a direction perpendicular to the wiring path.

Abstract: The present invention has an object of providing an electric wire connection structure for providing sufficiently high electric characteristics by welding and fixing a terminal and core wires, for providing the terminal with a strength sufficiently high to withstand the pressure at the time of welding, and for improving the adhesiveness of the core wires to the terminal by preventing the core wires from escaping at the time of welding. The electric wire connection structure is for connecting core wires (10) exposed at a tip end of a coated wire (12), including the core wires (10) covered with a insulating cover (11), to a conductive terminal (20). The terminal (20) includes a caulking portion (23) in which the core wires (10) are to be held by caulking, and a welding portion (22) to which the core wires (10) are to be fixed by welding. The caulking portion (23) and the welding portion (22) are arranged in a base portion of the terminal (20) in a longitudinal direction thereof.

Abstract: An electrical plug-provided cord has a cord including lead wires and an outer cover for covering the lead wires, an electrical plug including plug blades connected to the lead wires at a tip of the cord and a plug outer housing for covering a part of the cord and a part of the plug blades from base parts of the plug blades to the outer cover at a tip part of the cord, and a coupling member which surrounds the tip part of the cord in close contact and is coupled to the plug outer housing by thermal welding. The plug outer housing is formed of a synthetic resin. At least an interface of the coupling member with the plug outer housing is formed of a heat-weldable material which is thermally weldable with the plug outer housing.
