Abstract:
A card-edge connector for electrically connecting to a printed circuit board having a plurality of contact pads arranged on at least one side of an end portion of the printed circuit board, comprising:a connector housing having a recess into which the end portion of the printed circuit board is to be inserted, and a plurality of contact terminals, wherein each contact terminal is formed of a plurality of contact units wherein the contact units are stacked and wherein each contact unit comprises a fixed part to be secured to said connector housing and an elastically deformable spring piece section extending from said fixed part and having a contact point section at a distal end thereof to contact with at least one contact pad on said printed circuit board when said end portion of said printed circuit board is inserted into said card-edge connector, wherein: said plurality of stacked contact units are configured so that the contact point sections are distributed to disperse in the lengthwise direction of said corresponding contact terminal, each spring piece section of said plurality of stacked contact units, except the spring piece section of an innermost contact unit, comprises a fold at a midpoint thereby extending the spring piece section back toward the contact point section of the innermost contact unit and forming a hook-shape, the contact point section of said innermost contact unit is formed to be arcuate-shape, and a distal end of said innermost contact unit extends to a position at which it is not entangled with a distal end of an adjacent contact unit.
