Abstract

A connector has a frame (12) with passages (22) that hold contact assemblies (20), the contact assemblies having lower ends (114) soldered to traces (52) on a circuit board (54) and depressable upper ends, which provides low resistance within each contact assembly and which assures reliable soldering to traces on the circuit board. Each contact assembly includes a metal sleeve (60), a pogo tip (30) with a body (64) vertically slidable in the sleeve and a post (66) projecting above the sleeve, and a helical spring (72) that urges the pogo tip upwardly. The spring has an upper end (92) shaped to engage only one side of the bottom of the pogo tip body to cock the pogo tip for low resistance engagement with the sleeve. The spring is of much lower conductivity than the sleeve, to minimize current flow through the spring and unwanted inductance. The frame includes an elastomeric plate (84) that lies in an interference fit with each contact. The lower end (114) of each contact initially lies below standoffs (120), but slides upwardly when the connector is pressed down against a circuit board for soldering.
