Terminal fitting, connector and method for manufacturing terminal fitting

A connector comprising:

• a terminal fitting including:
• a first terminal portion in which a plurality of first tab portions, extending from a first tab continuous connecting portion, are arranged at intervals;
• a second terminal portion in which a plurality of second tab portions, extending from a second tab continuous connecting portion, are arranged at intervals;
• a connecting portion connecting the first terminal portion and the second terminal portion;
• and
• a contact portion to be connected to an external terminal;
• and
• a housing which includes a plurality of terminal accommodating chambers for accommodating the plurality of first tab portions and the plurality of second tab portions, and to which the terminal fitting is attached, wherein:
• the first terminal portion, the second terminal portion, the connecting portion, and the contact portion are continuous as a continuous conductor plate;
• the terminal fitting has a three-dimensional shape in which the terminal fitting having a preliminary shape, being flat plate-shape, is bent at the connecting portion;
• in the three-dimensional shape, the first terminal portion and the second terminal portion are three-dimensionally arranged to be connected at the connecting portion such that the plurality of the first tab portions and the plurality of the second tab portions are arranged in a predetermined arrangement direction, and the first tab continuous connecting portion and the second tab continuous connecting portion are arranged at intervals in an intersection direction intersecting the arrangement direction;
• and
• in the preliminary shape, the first terminal portion and the second terminal portion are arranged to be fitted to each other, and the first tab continuous connecting portion and the second tab continuous connecting portion are connected at the connecting portion such that the second tab portion is accommodated in the gap between the adjacent first tab portions, and the first tab portion is accommodated in the gap between the adjacent second tab portions.

A method for manufacturing a terminal fitting, including:

• a first terminal portion in which a plurality of first tab portions, extending from a first tab continuous connecting portion, are arranged at intervals;
• a second terminal portion in which a plurality of second tab portions, extending from a second tab continuous connecting portion, are arranged at intervals;
• a connecting portion connecting the first terminal portion and the second terminal portion;
• and a contact portion to be connected to an external terminal, in which:
• the first terminal portion, the second terminal portion, the connecting portion, and the contact portion are continuous as a continuous conductor plate;
• the terminal fitting has a three-dimensional shape in which the terminal fitting having a preliminary shape, being flat plate-shape, is bent at the connecting portion;
• in the three-dimensional shape, the first terminal portion and the second terminal portion are three-dimensionally arranged to be connected at the connecting portion such that the plurality of the first tab portions and the plurality of the second tab portions are arranged in a predetermined arrangement direction, and the first tab continuous connecting portion and the second tab continuous connecting portion are arranged at intervals in an intersection direction intersecting the arrangement direction;
• and in the preliminary shape, the first terminal portion and the second terminal portion are arranged to be fitted to each other, and the first tab continuous connecting portion and the second tab continuous connecting portion are connected at the connecting portion such that the second tab portion is accommodated in the gap between the adjacent first tab portions, and the first tab portion is accommodated in the gap between the adjacent second tab portions, the method comprising:
• manufacturing a preformed body in which the first terminal portion and the second terminal portion are fitted to each other and connected at the connecting portion such that the second tab portions are accommodated in the gaps between the adjacent first tab portions and the first tab portions are accommodated in the gaps between the adjacent second tab portions, by punching a flat plate-shaped conductor plate;
• and
• three-dimensionally arranging the first terminal portion and the second terminal portion such that the plurality of the first tab portions and the plurality of the second tab portions are arranged in the arrangement direction, and the first tab continuous connecting portion and the second tab continuous connecting portion are arranged at intervals in an intersection direction intersecting the arrangement direction, by bending the preformed body at the connecting portion.
