  • Electrical connector
    Patent number: 7357681
    Abstract: A board-mount electrical connector capable of maintaining favorable solderability of a connecting section of a terminal for a long term and preventing occurrence of a whisker in a bent section of the terminal is provided. The electrical connector includes a plurality of terminals each having at one end a contact section which contacts a mating contact and having, at the other end, a connecting section which connects to a circuit board. A bent section is located in a middle portion between the contact section and the connecting section. An insulating housing holds the plurality of terminals. On each terminal, a bright tin-plated layer and a semi-bright tin plated layer are formed on respective surfaces of the contact section and the connecting section leaving the surface of the middle portion unplated by tin such that the semi-bright tin-plated layer is thicker than the bright tin-plated layer.
    Type: Grant
