Abstract
Abstract An insulated electrical conductor terminal assembly comprising a "U" shaped clip (10) having pairs of opposed and aligned slots (13, 14) in opposite flanges (11, 12), which slots (13, 14) terminate in conductor seatings (15) adapted to have insulated conductors (16, 17) frictionally fitted therein through the slots (13, 14) across the flanges (11, 12) in tandem pairs. The clip (10) and its retained conductors (16, 17) are then fitted about a plurality of two-bladed terminals (22), one blade (23) of each terminal being bifurcated and having insulation piercing edges (27) at the opening of the bifurcation (26) and the other blade (24) of each terminal being bifurcated and having insulation piercing edges (27) at the base of the bifurcation (26). The cutting edges (27) of the two blades (23, 24) being spaced apart within each blade (23, 24) equal to the spacing between the seatings (15) of each pair of conductor seatings (15 ). Multiple simultaneous connections are thus made by a plurality of conductor pairs (16, 17) to the same respective terminals (22).
