PROBLEM TO BE SOLVED: To shield noise to and from the outside, and prevent contact failure, deformation of a lead, and position slippage of a connector mounted by arranging a lead plate on the connecting surface side of a gull wing type lead and a optical transceiver board. SOLUTION: A conducting layer becoming a shield plate is formed on the back side of a connector board 5 in which through holes corresponding to the number of connector pins 1 are perforated. The connector pin 1 is inserted into the through hole and connected with solder 6. The connector pin 1 is integrally formed with a gull wing type lead for being connected to a optical transceiver board 2, and the long insertion part according to the thickness of the connector board 5. A gull wing type lead for shield plate 14 is connected to the shield plate 4 with high melting point solder 8, molded with resin 16 to give strength to the connector pin 1. Shielding effect on the back side of the connector board 5 is enhanced with the whole surface shielding plate 4, the distance to the gull wing type lead is adjusted to adjust impedance, and the transmission of high frequency signals is made possible. |
