Abstract

An electrical contact is provided for press-fit insertion into a circuit board, which has a minimal antenna effect in radiating or receiving high frequency signals, while providing a large retention force (resistance to pullout). A compliant section (20, FIG. 4) of the contact is of the eye-of-the-needle type which includes a vertically-extending slot (44) that leaves a pair of largely vertical beams (46, 48) having outer sides (54) lying furthest from the slot. The lower portion (30) of the compliant section extends a small distance (N) below the bottom of the vertical slot, and is rounded to a radius of curvature (A) that is at least twenty percent of the maximum horizontal distance (G) between the outer sides of the beams, to produce a gradually rounded surface that minimizes radiation emission and reception. The outer sides of the beams are convexly rounded at a large radius of curvature (J) which is greater than the maximum distance (G) between the outer sides of the beams, to provide a large area of contact with the walls of the circuit board hole.
