A terminal assembly and connector, the terminal assembly comprises a first terminal component, a second terminal component, at least one metal shielding plate, and a metal housing. The first terminal component comprises a plurality of first signal terminals embedded in the first insulating body. The second terminal component comprises a second insulating body and a plurality of second signal terminals embedded in the second insulating body. The second terminal component is disposed opposite to the first terminal component. The at least one metal shielding plate connects with the first terminal component and the second terminal component. The metal shielding plate is disposed between the two adjacent first signal terminals and the two adjacent second signal terminals. The metal housing covers the first terminal component, the second terminal component and at least one metal shielding plate. The at least one metal shielding plate connects with the metal housing.

An electrical plug connector includes a metallic shell, an insulated member, plug terminals, and grounding members. The insulated member is in the metallic shell. The plug terminals are held in the insulated member. The grounding members and the insulated member are molded as a one-piece member, thereby reducing the production steps as well as reducing production of defect products. Moreover, the first curved contact portion extends toward the metallic shell and effectively contacts the metallic shell, and the second curved contact portion extends toward the ground terminal and effectively contacts the ground terminal.

A connector device includes a connector housing having a terminal accommodating chamber, a terminal configured to be accommodated in the terminal accommodating chamber, an electric wire configured to be connected to the terminal, a corrosion-proof material to be disposed at a position facing the terminal accommodated in the terminal accommodating chamber and a corrosion-proof target portion of the electric wire, and a corrosion-proof material support portion retaining the corrosion-proof material above the connector housing such that the corrosion-proof material can be moved toward the corrosion-proof target portion. A melting point of the corrosion-proof material is set to be lower than a melting point of a material forming the connector housing, and the corrosion-proof material is configured to be melted and then cured while covering the corrosion-proof target portion.

A connector includes a plurality of terminals, a first member made from a first resin to cover a part of a surface of each of the plural terminals, and a second member made from a second resin to cover a part of the surface of each of the plural terminals and a surface of the first member on the side opposite to the respective terminals. The plural terminals each project to be exposed from the surface of the second member. The first resin has breaking energy of 2 J or greater in a transverse direction. The second resin has a comparative tracking index of 400 V or greater.
