An insulation-displacement terminal fitting (10) has plate-shaped blades (27) disposed before V-shaped contact portions (23) along a wire-insertion direction. The blades (27) make cuts (C) in an insulation coating (Wb) of a wire (W). The insulation coating (Wb) then is cut open by the V-shaped contact portions (23). A cut-open piece (Wc) of the insulation coating (Wb) that is caught by the contact portions (23) is not forcibly stretched. Thus, a core (Wa) is not pulled in a direction to be withdrawn from a clearance between the contact portions (23). An accommodation space (30) in which the caught cut-open piece (Wc) of the insulation coating (Wb) is accommodated is located within a height range of side walls (21). Thus, the cut-open piece (Wc) of the insulation coating (Wb) does not project above the side walls (21).
An insulation-displacement terminal fitting (10) with a pair of opposed side walls (21), at least one pair of insulation-displacement portions (20), the insulation displacement portions (20) in each said pair projecting toward one another from the respective side walls (21) and configured to cut open an insulation coating (Wb) of a wire (W) pushed between the insulation displacement portions (20) and to bring a core (Wa) of the wire (W) into contact with the insulation-displacement portions (20), wherein the pair of insulation-displacement portions (20) comprise:
An insulation-displacement terminal fitting (10), comprising a bottom wall (16), first and second opposed side walls (21) extending substantially normally upward from the bottom wall (16), first and second insulation-displacement portions (20) extending toward one another from the respective first and second side walls (21), each said insulation-displacement portion (20) comprising a V-shaped contact portion (23) having front and rear panels converging toward one another and meeting at a contact edge (24) defining an apex of the V-shaped contact portion (23), said contact edges (24) being substantially normal to the bottom wall (16), each said contact portion (23) further comprising an upwardly facing shelf (26) extending substantially from the contact edge (24) toward the respective side wall (21), each said insulation-displacement portion (20) further comprising front and rear blades (27) extending upwardly from the respective front and rear panels of the V-shaped contact portion (23) at locations between the respective shelf (26) and the corresponding side wall (21), the blades (27) having cutting edges (28) aligned substantially parallel to the respective contact edges (24).
