ABSTRACT:
An insulation displacement contact terminal has a pair of side walls, an a pair of pressure contact blades that are mutually opposing and formed by partial bending away from the side walls. When an insulated wire is inserted between the pressure contact blades along a first direction, edges of the pressure contact blades bite into the insulation of the insulated wire so as to make contact with the inner core wire of the insulated wire. The pressure contact blades each have a curved part that is continuous from the side walls, and each curved part has a radius of curvature such that when the pressure contact blades are bent from the side walls and when a pulling force is applied to the insulated wire in a second direction that intersects with the first direction, concentration of bending stress acting on the pressure contact blades is relieved.
