PRESSURE-WELDING CONNECTOR, AND ASSEMBLY OF PRESSURE-WELDING CONNECTOR AND ELECTRIC WIRE

PROBLEM TO BE SOLVED: To prevent heterogeneous metal contact corrosion between a pressure-welding part penetrating through a coating material and a core wire of an electric wire electrically connected with the pressure-welding part.SOLUTION: A pressure-welding connector 1 has a pressure-welding part 112 penetrating through a coating material 91 of an electric wire 90 sandwiched between both first and second housings 11 and 12, and electrically connected to a core wire 92 of the electric wire 90, by pressure at the time when the first housing 11 and the second housing 12 are engaged with each other. The pressure-welding part 112 is provided to the first housing 11. To the second housing 12, a thermoplastic resin material 122 having a melting point lower than that of a material configuring the second housing 12 is provided at a position opposed to the pressure-welding part 112 provided to the first housing 11.
