Abstract: A solderless electrical connector construction for making connections between a plurality of conductor pairs (23) and a corresponding row of single, double-bladed (16, 17) insulation-piercing terminals (11) extending from the top surface (12) of a terminal block (10). The blades (16, 17) are oppositely directed from the ends of the terminals (11) and are adapted to seize and pierce the insulation of conductor pairs (23) maintained in vertical channels (21) in a pair of conductor mounting blocks (20, 30) as the latter are closed into abutment along the surface (12) of the terminals block (10). The channels (21) are extended around the mounting blocks (20, 30) to provide strain relief.

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 ).
