Abstract:
An insulation-displacement terminal fitting for a wire having a conductive core and an insulation coating around the core, the core and the insulation coating each having selected diameters, the insulation-displacement terminal fitting comprising a bottom wall, first and second opposed side walls extending from the bottom wall and defining a wire-receiving space therebetween, a first insulation-displacement portion projecting from the first side wall into the wire-receiving space, a second insulation-displacement portion projecting from the second side wall into the wire-receiving space and towards the first insulation-displacement portion, each of said insulation-displacement portions comprising a pair of wire guiding edges converging toward one another and slanted toward the bottom wall, a pair of spaced-apart cutting edges extending respectively from the wire guiding edges toward the bottom wall and being substantially normal to the bottom wall, each of said cutting edges having a bottom end, each of said insulation-displacement portions having a V-shape contact portion disposed between the cutting edges and the bottom wall, each of said V-shaped contact portions having an upwardly facing V-shaped shelf extending between the bottom ends of the spaced-apart cutting edges, such that the shelf and the respective cutting edges define a substantially U-shape, each of the V-shaped shelves having an apex spaced from the cutting edges, and a contact edge between the apex of the respective shelf and the bottom wall, the contact edges of the first and second insulation-displacement portions being spaced apart by a distance less than the diameter of the conductive core of the wire, the cutting edges of the first insulation-displacement portion being spaced from the cutting edges of the second insulation-displacement portion by a distance less than the diameter of the insulation coating, but greater than the diameter of the core.
