Abstract: A crimp terminal includes a terminal connecting portion, an electric wire connecting portion, and a coupling portion. The electric wire connecting portion is formed with a first barrel piece and a second barrel piece, the two facing each other, by bending processing on an electric wire side plate-shaped portion after two facing walls are formed by bending processing on a terminal side plate-shaped portion. The coupling portion is formed with two facing side walls by bending processing on a coupling side plate-shaped portion. Certain portions that will be the side walls later are formed with at least one tensile force absorbing portion that absorbs a tensile force between the terminal side plate-shaped portion side and the electric wire side plate-shaped portion side occurring during the bending processing on the terminal side plate-shaped portion.

Abstract: A terminal fitting includes a terminal connecting portion and an electric wire connecting portion. A water stop member is affixed to an inner wall surface of the electric wire connecting portion before crimping process and suppresses entering of water between the electric wire connecting portion and a core wire of the electric wire after the crimping. The electric wire connecting portion is formed into a U-shape by raising the first barrel piece and the second barrel piece from both ends of the bottom. The distal end of the first barrel piece is bent toward the second barrel piece, to form a gap between a slide contact surface on a descending second die and the distal end of the first barrel piece.

Abstract: A connector includes a connector housing, a plurality of terminals including foot portions extending to the outside of the connector housing, and a position aligning plate including a plurality of terminal insertion holes, the foot portions of the terminals being configured to be inserted into the terminal insertion holes so that the foot portions align with corresponding through holes of a circuit board. The foot portions of the terminals are configured to be soldered with the circuit board by a reflow system using hot air as a hearing source. A vent hole is provided in the position aligning plate to introduce the hot air to soldering parts through the vent hole.

Abstract: A connector includes a connector housing provided with multiple terminal housing chambers. The multiple terminal housing chambers are separated by top walls, bottom walls, and side walls. Lances are supported by the bottom walls of the terminal housing chambers, which are located on the same surface side. Each of the bottom walls includes a cutout portion which avoids interference with the lance when the lance bends in a direction to retreat from the terminal housing chamber. Each lance bends in the direction to retreat from the terminal housing chamber when a terminal is inserted into the terminal housing chamber. When the terminal is fully inserted into a regular insertion position, each lance recovers from flexural deformation and is locked to the terminal.
