Electrical connector having board retention means

An electrical connector (20) includes a housing (22) and an array of terminal members (28) having posts (46) extending from the housing (22) and adapted for insertion into through-holes (72) of a circuit board (70). At least one board retention means (48) is formed on at least one of the posts (46) and is axially located a selected distance from the lower surface of the housing (22) to be within a corresponding through-hole (72) after insertion. The retention means is a swage defining wall engaging surfaces for engaging sidewalls of a respective through-hole (70) during mounting of the connector (20) to board (70). The swage (48) is formed such that the far side of the post (46) remains coplanar with the axially adjacent surfaces and a swage embossment extends laterally outwardly from at least the second side, the embossment being formed by the work end (84) of a tool (82) striking the third side at an angle.
