(57) An electrical contact unit (100) is disclosed, having a series of four electrical
receptacles (102, 104, 106, 108). Each of the receptacles includes an upper cantilever
member (110) and a lower cantilever member (112). Upper lateral arms (114) are conductively
interconnected by an upper bridge portion (116). Correspondingly, lower lateral arms
(118) are conductively interconnected by a lower bridge portion (120). The upper lateral
arms (114) and upper bridge portion (116) provide a pair of contact surfaces or edges
(122). Correspondingly, the lower lateral arms (118) and lower bridge portion (120)
form a pair of lower contact surfaces or edges (124). In addition, an upper cantilever
member (128) positioned inwardly of the upper lateral arms (114) is also provided.
A lower and inner cantilever member (130) is disposed directly below the upper and
inner cantilever member (128) and is located in a spatial area formed by the lower
lateral arms (128) and lower bridge portion (120). The inner and upper cantilever
member (128) is shaped so as to form a contact surface (140) on a lower surface thereof.
Correspondingly, the lower and inner cantilever member (130) is shaped so as to form
an electrical contact surface or edge (142) on an upper surface thereof.
