A terminal includes a conductor connecting part, a terminal connecting part, and a graphene film. When a first metal material and a third metal material forming a conductor of an electric wire have different ionization tendencies, the graphene film is provided to be arranged between a first surface and the conductor of the electric wire when the conductor of the electric wire is electrically connected to the conductor connecting part. When a second metal material and a fourth metal material forming a surface of an opposite terminal have different ionization tendencies, the graphene film is provided to be arranged between a second surface and the surface of the opposite terminal when the opposite terminal is electrically connected to the terminal connecting part.

This terminal-equipped electric wire for a charging inlet comprises: an electric wire that has a conductor and an insulation coating; and a terminal that is connected to the conductor exposed on the end part of the electric wire. The insulation coating has an olefin resin as the main component thereof. The terminal-equipped electric wire further comprises: heat-shrinkable tubing that covers a region spanning from a site where the conductor and the terminal are connected to the insulation coating; and a primer layer that is provided between the inner peripheral surface of the heat-shrinkable tubing and the outer peripheral surface of the terminal. The inner peripheral surface of the heat-shrinkable tubing and the outer peripheral surface of the insulation coating are in direct contact.

A terminal-equipped electric wire includes a terminal to be electrically connected to a connection target member, and an electric wire to be connected to the terminal by ultrasonic joining. The terminal includes a joint portion to be connected to the electric wire, a connection portion to be connected to the connection target member, and a plating layer on a surface of the terminal. The connection portion has an uneven shape on at least a part of a surface thereof. When the terminal-equipped electric wire is connected to the connection target member, an insulating coating of the plating layer covering at least a part of the surface of the connection portion is broken.

A connector assembly for an electrical connection, the connector assembly includes a plug and a socket. The plug includes a connector and a frame. The connector has a solid core conductor, the solid core conductor has an end portion. The frame surrounds the solid core conductor except for the end portion. The end portion is deformed to overlap the frame. The socket includes a socket conductor and a receiving portion into which the plug engages. The end portion directly contacts the socket conductor to form an electrical contact and causes the frame to deflect and provide a bias to force the end portion and the socket conductor into direct contact with one another.
