Abstract: A connector has a connector terminal that has a connecting section for a partner terminal on one end of a conducting plate, a board insertion section on the other end, and a curved section for absorbing the deviations in the vertical. The connector also has horizontal directions in the middle of the conducting plate, and a housing which houses the connector terminal which has a board mounting plate on the side of the base end, and the board mounting plate mounted so as to be horizontally movably on the board via a fixing stand of the board insertion section.

Abstract: A male terminal for electrical connection fittable to a female terminal includes; a tab as an electrical connection section, which is fitted to a tab receptacle of the female terminal when the male terminal is fitted to the female terminal sheet, and at least one recess formed on the one side of the tab so as to be contactable with protruding contact member provided on the tab receptable of the female terminal. The recess is formed by forging processing. The depth of the recess is adjusted in accordance with the width of a space of the tab receptable so as to be able to adapt to various sizes and shapes of the female terminal.

Abstract: A connector has at least one connector terminal which includes two electrical contacting sections connectable to partner terminals and a deformable plate connected between said electrical contacting sections and bent so as to shorten a distance between the electrical contacting sections, wherein said deformable plate sections comprises a first deformable plate portion for allowing said two electrical contacting sections to displace forward or away from each other in a first direction and a second plate portion for allowing said electrical contacting sections to displace in a second direction perpendicular to the first direction, and a set of connector housing for accommodating said electrical contacting sections therein, respectively. One of said connector housings is displaceably assembled to the other connector housing such that a deviation between the electrical contacting section and the partner terminal can be corrected by adjusting the position of the displaceable connector housing.
