Board connector

A board connector, comprising:

• a housing formed with a terminal holding portion, the housing being mounted on a mounting surface of a circuit board;
• a plurality of first long and narrow terminal fittings each including a first board connecting portion extending in a front-rear direction and to be fixed to the mounting surface behind the terminal holding portion and a first terminal connecting portion penetrating through the terminal holding portion in the front-rear direction, the first terminal connecting portions being mounted in the terminal holding portions at first heights from the mounting surface;
• and
• a plurality of second long and narrow terminal fittings each including a second board connecting portion extending in a front-rear direction and to be fixed to the mounting surface behind the terminal holding portion and a second terminal connecting portion penetrating through the terminal holding portion in the front-rear direction, the second terminal connecting portions being mounted in the terminal holding portions at second heights from the mounting surface, the second heights being greater than the first heights;
• wherein all of the terminal fittings have equal lengths, and wherein the first board connecting portion of each of the first terminal fittings includes an extra link with a length equal to a height difference between the first height and the second height, the extra length link linking a front end of the board connecting portion of the first terminal fittings and a rear end of the terminal connecting portion of the first terminal fittings.
