A terminal bending tool comprises a plate, a plurality of receiving grooves, and a plurality of rollers. The plate extends in a first horizontal direction. The receiving grooves are disposed in the plate in a row along the first horizontal direction. The rollers are pivotally mounted in the receiving grooves. A terminal is received and positioned in a first receiving groove and is in contact with an outer circumferential surface of a first roller. When the terminal bending tool is moved in a vertical direction perpendicular to the first horizontal direction, the first roller rotates and moves along a surface of the terminal while pressing and bending the terminal.
