Abstract

An electric contact using resin solder is connected to a printed circuit board, which has a conductor provided on a surface thereof. This electric contact comprises a leg, which contacts the conductor of the printed circuit board, and a connecting part, which is connected to the conductor of the counterpart member. At least a part of the leg, which contacts the conductor of the printed circuit board, is made of a lead-free ultrahigh-conductive plastic being a conductive resin composite. An electric connector includes the electric contact and an insulating housing, which holds the electric contact so that the part of the leg, which contacts the conductor of the printed circuit board, is exposed.

An electric contact using resin solder, which is connected to a printed circuit board, which has a conductor being provided on a surface thereof,

the electric contact comprising a leg, which contacts the conductor of the printed circuit board, and a connecting part, which is connected to a conductor of a counterpart member, and
at least a part of the leg, which contacts the conductor of the printed circuit board, is made of a lead-free ultrahigh-conductive plastic being a conductive resin composite, comprising a thermoplastic resin, a lead-free solder that can be melted in the plasticated thermoplastic resin, and powder of a metal that assists fine dispersion of the lead-free solder in the thermoplastic resin or a mixture of the powder of the metal and short fibers of a metal.

Dependencies are inferred from the claim text.
