Abstract
An electrical contact (10b) comprises a pin contact portion (1b), a press-fit portion (2b), and a terminal portion (3b) integrally formed from a metal sheet which has a flat surface defined by X and Z directions and a predetermined thickness in a Y direction. The press-fit portion as a first flat portion extends in the Z direction with a first end (2b.alpha.) and a second end (2b.beta.) opposite to each other. The pin contact portion extends from the first end in the X direction. The terminal portion as a second flat portion extends from the second end continuously in the X and the Z directions with a leg portion (3b.alpha.) extending in the Z direction and a foot portion (3b.beta.) extending from the leg portion in the X direction. The foot portion serves as a connecting portion to be connected to a conductive portion formed on an electrical circuit board. A method of manufacturing the electrical contact comprises a punching process in which the metal sheet is punched in the Y direction to form a contact blank having a temporary pin contact portion, the press-fit portion, and the terminal portion, and a pin-forming process in which the temporary pin contact portion is press-formed in the Z direction to obtain the pin contact portion having a generally circular cross section of a diameter greater than the predetermined thickness.
