Abstract
An insulation-piercing connector includes a terminal block having therein a plurality of piercing terminals, and a piercing block having wire receiving apertures. When the terminal and piercing blocks are forced closer together, insulated wires of a cable received in the wire receiving apertures of the piercing block are forced into U-shaped grooves of the piercing terminals so that inner edges of the U-shaped grooves pierce into conductors of the insulated wires to electrically connect between the conductors and the piercing terminals, respectively. The piercing block is further formed at the forward ends of the wire receiving apertures with U-shaped grooves whose opposed walls form flanges which may be tapered toward each other. A distance between the opposed walls of the U-shaped grooves is less than the outer diameter of the insulated wires but more than the outer diameter of the conductors of the wires.
