Abstract

A circuit board has an electrical contact in the form of a tube that is set into the board. The board carries an array of tubes. A circuit card that is to be plugged into the board has pin-like bendable beams that fit loosely into a matching tube when the card is initially positioned on the board. The card grips the beam at a point that is spaced from the rim of the tube, and when the card (or the board) is moved laterally, the rim of the tube strikes the beam at a point midway between the free end of the beam and the point where the beam is gripped by the card. This initial motion establishes a first point of electrical contact between the midpoint of the beam and the rim of the tube.
