Abstract
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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
187 words
A box terminal, for reception of a rectangular terminal pin, including a main body box portion and a tail portion; the main body portion of elongate form having a rectangular cross-section normal to the longitudinal axis, and including an entry end and an exit end, said tail portion extending from said exit end; said main body portion having four side members forming first and second pairs of side members, the side members of a pair in opposition; each of the first pair of side members including an extension bent back inside the side member from said entry end to form a cantilever portion extending from and cantilevered from the entry end and resiliently biased inwardly to form a cantilever spring contact member, each cantilever portion having a free end extending towards said exit end and spaced inwardly from the related side member and a domed contact area adjacent to the free end of each spring contact member; the second pair of side members extending only to said entry end, each member being deformed inwardly intermediate the ends of the member to form a domed pin engaging formation.
Claim 2
Dependent Claim
