Abstract: A C-shaped compliant contact is composed of a connection portion to be connected to an electric cable or the like, a press-fitting portion to be press-fitted in a through-hole of the printed circuit board, and a contact portion to contact a contact of a mating connector. The press-fitting portion has an inner periphery forming a U-shaped groove in section and an outer periphery forming at least one arc portion. The circle inscribing the inner periphery of the U-shaped groove is in an eccentric relation to the arc portion of the outer periphery. The thickness of the arc portion in cross-section progressively decreasing on proceeding toward the open end of the U-shaped groove to make longer the arc portion contacting the through-hole of the printed circuit board. The U-shaped groove is formed with a ramp surface located inside the inner periphery near to the connection portion, connected to the bottom of the U-shaped groove and inclined to make shallower the U-shaped groove, thereby preventing the connection portion of the contact from being bent when it is being press-fitted into the through-hole of the printed circuit board.
