<p>In an electrical connector of the kind comprising a wedge (2) adapted to trap wires between sides of the wedge (2) and complementary sides of a generally C-shaped receptacle (1), the wedge (2) at its leading end is formed with a weakened zone (8) adapted to allow penetration of a tool spike (12), on driving the wedge (2) into the receptacle (1), and deformation of metal at a side of the zone (8) to engage an end face of the receptacle (1) and thereby secure the wedge (2). This allows use of harder metals than the conventional copper or aluminium, e.g. aluminium or manganese bronze, which allow for interconnection of aluminium and copper cables without galvanic corrosion problems.</p> |
