ABSTRACT:
A three-way nip contact type contactor has first, second and third contacting pieces connected together at their base end portions and arranged side by side in rows extending toward their top end portions. The first and second contacting pieces are arranged to form two sides of a triangle and the third contacting piece is arranged to form the remaining side. A male terminal is nipped by and among the first through third contacting pieces to obtain a contacting relation between the male terminal and each of the first through third contacting pieces. The third contacting piece is provided at its top end portion with a pressure bearing portion. The third contacting piece, when an external force is applied to the pressure bearing portion, is displaced in an opening direction against its elasticity to permit the male terminal to be inserted into and among the first through third contacting pieces. When the third contacting piece is elastically restored in a closing direction and presses against a side surface of the male terminal, the first and second contacting pieces are displaced in the opening direction against their elasticity by a pressing force of the third contacting piece, and slidingly move on the side surface of the male terminal during their displacement in the opening direction.
