ABSTRACT:
A daughterboard connector (6) has a polarity key formed by two walls (14, 15) on either side of a recess (12). A lateral contact (8) mounted in the recess engages a bus bar (3, 4) which is mounted in a pair of slots (20) in the end of a motherboard connector (11). A flange (7) adjacent one of the slots forms a polarity key for the motherboard connector. The height and positioning of the lateral contact and the bus bar are chosen to provide a first-make-last-break function for these elements relative to the signal contacts 19 and 16 of the daughterboard and motherboard connectors, respectively. The bus bar (3, 4) may be common to a number of motherboard connectors which are mounted on a common printed circuit board.
