  • Patent number: 3967873
    Abstract: A wire terminal electrical contact is provided to accommodate wires of a wide range of diameters. The terminal is of the push-in type and includes a metal strip having spring properties within an insulating housing. Openings to the housing through which the wire is pushed to make contact accept the full range of wire diameters normally employed in household wiring ranging from No. 10 gauge to No. 14 gauge. Locking cams are formed from the spring metal strip by an F configuration of slits to form two side-by-side locking tongues. The free ends of the tongues are bent up from the strip to the housing interior and two adjoining openings are provided in the housing aligned with the vertical portion of the F. The openings are circular and accept the largest and smallest diameter wires. Also the openings intersect, but their area of intersection is smaller than the smallest diameter wire which will be used in either of the holes.
