assembly includes a connector (100) and a circuit board (140). The
connector includes a insulative base (110) and a plurality of contacts
(124, 126, 128) extending from the insulative base and being soldered to
the circuit board at one end thereof. The baseplate receiving the circuit
board and the connector, includes a bottom wall (36), two side walls (39)
and two separating walls (34) extending perpendicularly from the bottom
wall. The insulative base of the connector, the bottom wall, the two side
walls and the two separating walls corporately form three contacts
