ABSTRACT:
A box terminal, particularly for card edge receptacles in telecommunications systems is in the form of a hollow box structure having opposed lever arms with contact areas at the ends of the arms, and with opposed formations on a plane normal to the plane containing the lever arms. The opposed formations restrict lateral displacement of a pin entering the box and, with the beams, restrict rotational displacement of a pin. Contact occurs on at least two prime surfaces, that is on flat surfaces. The beams are preloaded to control insertion forces.
