A terminal connecting method includes setting a conductor having a plurality of strands on an upper surface of a bottom portion of an electric wire crimping part of a terminal, caulking the conductor in a manner to cover the conductor, thereby crimping the conductor by a caulking portion extended from the bottom portion, and welding the plurality of strands together in a strands exposed portion of the conductor exposed from tip end edges of the caulking portion by friction between the plurality of strands and a friction tool, after caulking and crimping.

Terminal connecting method

An aluminum electric wire crimping terminal formed by connecting an aluminum electric wire and a crimping terminal includes a low compression concave portion and a high compression concave portion in a crimping portion. The high compression concave portion compresses a plurality of core wires with a stronger compression force than a compression force of the low compression concave portion.

Aluminum electric wire crimping terminal, crimping device and crimping method

An electric wire with a connecting terminal and a method for manufacturing the electric wire are provided. The electric wire has a plurality of wire conductors and an insulation cover that covers the wire conductors. The plurality of wire conductors includes the connecting terminal to be connected to a counterpart component at an end of the electric wire at which the plurality of wire conductors is stripped of the insulation cover. The connecting terminal has a first portion of the plurality of wire conductors, a second portion of the plurality of wire conductors folded back on top of the first portion, the first portion and the second portion being welded to each other, and a through hole extending through the connecting terminal at a location where the first portion and the second portion are welded to each other.
