Claim 7

An electrical connector for press-in connection with a conductor, said connector comprising: a plurality of electric terminals, each comprising; a base, a first rectangular tine, a second rectangular tine and a third rectangular tine, each extending upward from said base, said first rectangular tine and said second rectangular tine located adjacent and spaced sideways from each other and said third rectangular tine located displaced laterally away from a line between said first and second rectangular tines and adjacent the center of the space between said first and second rectangular tines, the front surfaces of said first and second rectangular tines facing in the direction in which said third rectangular tine is laterally displaced and opposite the direction of facing of the front surface of said third rectangular tine, and said first, second and third rectangular tines positioned so that the side surfaces of said first and third rectangular tines, which are closest each other, define an x 1 axis, the side surfaces of said third and second rectangular tines, which are closest each other, define an x 2 axis which is parallel to said x 1 axis, and the front surfaces of said first, second and third rectangular tines define a y axis which is perpendicular, in the same plane, to said x 1 and x 2 axes, a first bevel surface on said first rectangular tine at the corner closest said third rectangular tine, a third bevel surface on said third rectangular tine at the corner closest said first rectangular tine, said first and third bevel surfaces spaced opposite and parallel to each other for defining a first space for receiving a conductor therein; a second bevel surface on said second rectangular tine at the corner closest said third rectangular tine, a fourth bevel surface on said third rectangular tine at the corner closest said second rectangular tine, said second and fourth bevel surfaces spaced opposite and parallel to each other for defining a second space for receiving a conductor therein, whereby a conductor can be inserted into said first and second spaces between said bevel surfaces for establishing a physical and electrical connection between said terminal and the conductor through direct contact between the conductor and said bevel surfaces; a base block having a shape for receiving said plurality of terminals in at least two parallel rows; an intermediate block having a plurality of holes for allowing each tine of each terminal of said plurality of terminals to pass therethrough and for holding the base portion of each rectangular tine thereon; and a top block having a plurality of openings for receiving and holding the tops of said rectangular tines which protrude from the top of said intermediate block.
