Abstract:
A terminal fitting for an insulated wire with a core and an insulation coating surrounding the core, the terminal fitting comprising a pair of opposed sidewalls and at least one insulation displacement contact portion formed along the sidewalls, the insulation displacement contact portion being electrically connectable with the core of the insulated wire by cutting the insulation coating as the insulated wire is pushed into the insulation displacement contact portion, the insulation displacement contact portion comprising two opposed V-shaped cutting blades for cutting the insulation coating of the insulated wire and two opposed contact portions disposed respectively below the cutting blades in an insertion direction of the insulated wire, the contact portions being defined by embossing the sidewalls of the terminal fitting inward to define embossed portions that have triangular cross sections a ridge defining an apex of each of the embossed triangular contact portions, the ridges being dimensioned for tightly holding the core between opposed ridges of the embossed triangular contact portions, each said V-shaped cutting blade defining an apex intersecting the respective ridge of the embossed triangular contact portion at an acute angle, each said insulation displacement contact portion further having two opposed embossed triangular guide portions disposed above and spaced from the respective V-shaped cutting blade for guiding the wire toward the cutting blades of the respective insulation displacement contact portion, each said guide portion further having a ridge aligned with the ridge of the respective embossed triangular contact portion and with the apex of the respective cutting blade.
