Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A terminal connecting method comprising: 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, wherein the welding includes first contacting the friction tool with the strands exposed portion, wherein the plurality of strands in the strands exposed portion and the tip end edges of the caulking portion are adhered together by the friction between the plurality of strands and the friction tool and friction between the tip end edges and the friction tool, wherein a rotational axis of the friction tool is perpendicular to an extending direction of the plurality of strands, wherein the plurality of strands are pressed from a tip end side of the strands exposed portion, and adhered together by the friction between the plurality of strands and the friction tool, and wherein the plurality of strands are pressed and rubbed by the friction tool while the friction tool moves in a terminal width direction along the tip end side of the strands exposed portion. 2. The terminal connecting method according to claim 1 , wherein the conductor comprises a bundle of the plurality of strands exposed from a plurality of electric wires by peeling off insulating coatings therefrom. 3. The terminal connecting method according to claim 1 , wherein the plurality of strands are made of aluminum or aluminum alloy. 4. The terminal connecting method according to claim 1 , wherein the welding includes contacting the friction tool to an end face of the strands exposed portion. 5. The terminal connecting method according to claim 1 , wherein in the welding, a side surface of the friction tool extending along the rotation axis contacts the plurality of strands in the strands exposed portion and the tip end edges of the caulking portion.
