Abstract
An electrical device for surface mounting on a circuit board comprises a housing and a plurality of contacts wherein the distance between the region at which the pad-engaging portion of each contact engages its respective pad, and the region of the fulcrum about which the contact deflects, is maximized to reduce the magnitude of the biasing force resulting from the deflection. An improved mounting component for the device comprises a post having tangs that extend from its side which are deflected to allow the post to be inserted into the board opening and which skive into the sides of the opening to prevent the post from retraction therefrom. An improved positioning arrangement for the device comprises a pair of positioning posts having polygonal cross-sections, each having a maximum cross-sectional dimension in single, mutually orthogonal, directions.
