  • Patent number: 4012107
    Abstract: A female contact particularly useful as a low profile contact inserted in a printed circuit board and comprising a tubular portion with a flared open end for receiving a male pin. A pair of opposing contact fingers extend from the flared open end and are folded back upon themselves to extend downwardly into the interior of the tubular portion. Near the open end of the tubular portion the two opposing fingers are initially close to, and substantially parallel to, the walls of the tubular portion. As they extend further into the tubular portion, the curved fingers extend away from the walls of the tubular portion and towards each other, with their concave surfaces facing each other. As a terminal post is initially inserted between the fingers the fingers are deflected apart and outwardly towards the walls of the tubular portion so that a point on said fingers will be forced against the wall of the tubular portion.
