Electric connecting device and electric connector using resin solder and method of connecting electric wire to them

摘要

The objectives of the present invention include to connect an electric wire to the electric connecting device without soldering work and to connect a very fine wire to the electric connecting device by means of an automatic machine. The electric connecting device according to the present invention comprises a first connecting part which couples with a counterpart member or fits with a counterpart member, and a second connecting part to which the conductor of an electric wire is connected. In this electric connecting device, at least a part of the second connecting part to which the conductor of the electric wire is connected is made of a led-free ultrahigh-conductive plastic being a conductive resin composite.
