ABSTRACT:
A terminal, and methods for manufacturing the terminal, in which the opening defined by the electric contact portion is filled with a material. As a result, plating solutions will not become entrapped in the opening so that corrosion of the terminal will be prevented. The terminal includes an electrically conductive plate including a wire connecting portion for clamping a wire thereto and an electric contact portion for mating with another terminal, the contact portion including a cavity therein; and a filler material disposed in the cavity. As a result, when the terminal is subjected to metal plating, solutions associated with the metal plating are substantially prevented from entering into the cavity. According to one method, the filler material is first adhered to the conductive plate before the plate is bent into the shape of the terminal. According to a second method, the filler material is injected into the cavity of the contact portion after the terminal has been bent.
