Claims (1)
ジコネクタへ挿入することにより、該コネクタの
接触子と前記導電端子とが電気的に接触する印刷
配線板であつて、前記カードエツジコネクタへの
挿入開始位置から挿入完了位置までの接触抵抗が
段階的に変化するように前記導電端子が形成され
たことを特徴とする印刷配線板。 A printed wiring board having a conductive terminal at an end, and by inserting this end into a CardEdge connector, a contactor of the connector and the conductive terminal are electrically contacted, the printed wiring board being connected to the CardEdge connector. The printed wiring board is characterized in that the conductive terminal is formed so that the contact resistance changes stepwise from the insertion start position to the insertion completion position.
