ABSTRACT:
A terminal and terminal block for connecting an insulated wire to electrical circuitry, without stripping and preparing the wire. The terminal has a pair of opposing spring arms, whose parallel edges define a wire-receiving slit. The terminal block has a base, in which the terminal is provided, and a top. In a first terminal block position, base and top allow a wire to be inserted into the block and laid over the terminal. The top is movable toward the base to reach a second terminal block position in which base and top are locked together. The motion of the top relative to the base forces the wire into the terminal slit; the edges slice the insulation to make electrical contact with the wire. The terminal remains compliant over a wide range of wire sizes. A clinch spring is provided in the terminal block top and provides additional retention of the wire in the block and resistance to pulling or twisting.
