Abstract
A press-in contact has a press-fitting portion which is press-fitted in a cylindrical through-hole of a printed circuit board, thereby fixing the press-in contact to the circuit board. The cross-section of the press-fitting portion of the press-in contact includes a U-shaped inner edge and an outer periphery having two arc parts and a straight part therebetween. The circular part of the U-shaped inner edge at its bottom and the two arc parts of the outer periphery are in eccentric relation of shifted centers. The thickness of the arc parts is progressively thinner toward the open ends of the U-shaped inner edge, and a circumferential length of the arc parts of the outer periphery contacting the through-hole of the printed circuit board is as long as possible. With the press-in contact thus constructed, no whitening occurs in the proximity of the through-hole of the printed circuit board even if the holding force for the contact is more than 5 kg.
