Terminal fitting with welded portion

摘要

A terminal fitting (10) includes a terminal main body (21) with a bottom wall (22) on which cores (71) of wires (70) are placed, and two side walls (23) that stand up from opposite lateral sides of the bottom wall (22). A welding portion (25) where the cores (71) are welded to the bottom wall (22) is formed at a front part of the terminal main body (21). A crimping portion (26) is formed at a rear part of the terminal main body (21) and has crimping pieces (27) projecting from upper ends of the side walls (23) for crimped connection to the wires (70). Cutouts (28AF, 28AR) are cut into the upper end of the side wall (23) of the crimping portion (26) at front and rear sides of the front crimping piece (27F) while retaining parts of the side wall (23L) below the cutouts (28AF, 28AR).

主权项

1. A terminal fitting having opposite front and rear ends and comprising:
a mounting portion at the front end and configured for connection to an object; a terminal main body extending rearward from the mounting portion, the terminal main body having a bottom wall extending in forward and rearward directions and a step formed at an intermediate portion of the bottom wall in an extending direction to define an elevated portion rearward of the step, a welding portion formed on the elevated portion and configured to have wires welded thereon, side walls projecting from opposite lateral sides of the bottom wall and having substantially uniform heights along an entire length of the welding portion; and a crimping portion rearward of the welding portion, the bottom wall and the side walls extending continuously into the crimping portion, front and rear crimping pieces projecting from upper ends of the side walls at the crimping portion, a distance from the front crimping piece to the welding portion being less than a distance from the rear crimping piece to the welding portion, cutouts being cut into the upper end of the side wall at least at front and rear sides of the front crimping piece so that parts of the side wall at the cutouts are lower than parts of the side walls at the welding portion, whereby the cutout forward of the front crimping piece prevents transmission of crimping forces to the welding portion.
