Abstract

A miniature socket contact (10, FIG. 1) is described which fits within the thickness of a device such as PC board plated hole (20), which is firmly retained within the hole, without damage to the hole plating during removal, and wherein each pin-contacting beam (70, 72) has two points of contact with an inserted contact pin (14). The contact is formed of sheet metal and has an upper retention portion (30) forming retention tabs (42-46), with each tab having an inner part (50) extending radially inwardly, an outer part (56) extending radially outwardly with a tip (60) that presses against the hole walls, and a bent middle (54) that guides an inserted pin and is preferably deflected outwardly by the inserted pin to press the tab tip firmly against the hole walls. The contact has a lower contacting portion (32) forming a pair of downwardly converging beams (70, 72) whose lower ends engage the inserted pin. As seen in a view (FIG. 6) along the contact axis, the inner edge (74e, 76e) of each beam lower end has a sharply curved middle (110) spaced from the pin (14) and opposite sides that each have a pin-engaging location ( 116, 118).
