ABSTRACT:
A connector (22) includes a housing (24) having an array of first terminal-receiving passageways (34) each in communication with a spring arm receiving recess (38), each passageway (34) having a terminal member (50) disposed therein. Each terminal member (50) includes a body section (52) having a first connecting portion (54) adapted for surface mount engagement with a circuit pad (122) of a circuit board (120) and a spring arm portion (60). The spring arm portion (60) has a first transverse portion (62) extending laterally from the terminal member (50) proximate the first connecting portion (54), an axial portion (64) of a selected length extending from the first transverse portion (62) and toward a second connecting portion (72) of the terminal member (50), and a second transverse portion (68) extending toward the body section (52). The first transverse portion (62) extends essentially parallel to the mounting face (28) and is recessed therefrom. The second transverse portion (68) is adapted to engage with a biasing surface 44 of the recess (38) such that upon mounting the connector (22) to board (120) the biasing surface (44) exerts pressure thereagainst to bias the first connecting section (54) against the circuit pad (122), the spring arm (60) providing increased normal force to the contact interface while remaining outside the path of the flow of current between the terminal member (50) and the circuit pad (122).
