Abstract
Each the contact terminal includes a plurality of contact units stacked with each other, wherein contact point sections of the respective contact units are distributed to disperse in lengthwise direction of the contact terminal within the corresponding contact pad. The distal end of the innermost contact unit in the plurality of stacked contact units extends to a position at which it is not entangled with the distal end of the adjacent contact unit.
Claims8
A card-edge connector comprising a connector housing having a recess into which is inserted a printed circuit board having a plurality of contact pads arranged on at least one side of an end portion thereof, and
- a plurality of contact terminals, each having a fixed part to be secured to said connector housing, an elastically deformable spring piece section extending from said fixed part and having a contact point section at a distal end thereof;
- said card-edge connector bringing said contact pads on said printed circuit board inserted thereinto into contact with said contact point sections of the plurality of contact terminals,
- wherein said contact terminal is formed of a plurality of contact units stacked with each other so that said contact point sections of said respective contact units in each layer are distributed to disperse in the lengthwise direction of said contact terminal within said contact pad, and
- spring piece sections of said contact units except an innermost contact unit is folded back at a midpoint to be formed a hook-shape, a contact point section of said innermost contact unit is formed to arcuate-shape, and
- a distal end of said innermost contact unit in the plurality of stacked contact units extends to a position at which it is not entangled with a distal end of said adjacent contact unit.
A card-edge connector comprising:
- a housing portion in which a connecting section of an edge board is selectively accommodated;
- said connecting section having first and second groups of electrode pads for said electrical connection formed respectively in a pair of planes opposite to each other;
- a positioning section for positioning said connecting section of said edge board accommodated in said housing portion so that an array of said first and second groups of electrode pads direct in a predetermined direction;
- a group of contact terminals arranged within said housing portion along said arrangement direction of said first and second groups of electrode pads in said edge board and electrically connected with said first and second groups of electrode pads of said edge board positioned by said positioning section;
- wherein said groups of contact terminals comprises
- first contact terminals, each having a plurality of contact point group formed in substantially said same plane and arranged in direction generally orthogonal to said arrangement direction of said electrode pads in said first group to be in contact with different positions in one electrode pad in said first group, and
- second contact terminals arranged opposite to said first contact terminals at a predetermined distance, respectively, each having a plurality of contact point group formed substantially in said same plane and arranged in direction generally orthogonal to said orthogonal arrangement direction of said electrode pads in said second group to be in contact with different positions in one electrode pad in said second group.
