A terminal assembly includes a wire including a core made of metal and covered with a coating, a terminal including a wire connecting portion connected to an end portion of the wire, a sealing resin sealing the wire connecting portion, and a housing including a through hole with a front opening and a rear opening. The terminal is made of a different kind of metal from the core of the wire. The housing accommodates the terminal in the through hole. The wire connecting portion includes an exposed portion not covered with the sealing resin and unexposed portions covered with the sealing resin. The exposed portion is positioned between the unexposed portions in a front and rear direction, thereby protecting the wire connecting portion from electrolytic corrosion. The exposed portion is obtained after the sealing resin is worn by being rubbed against an inner wall of the through hole.

Anti-corrosion structure for wire connecting portion

A female terminal has left and right stabilizers () extending from one surface of a rectangular tubular main portion (). The stabilizers () are formed at predetermined distances in from opposite left and right lateral edges of the surface of the main portion () toward a widthwise center and assume oblique postures so that both extending ends gradually come closer to each other. The extending ends of the both stabilizers () are located within a circumscribed circle (X) of the main portion (), C-surfaces (A) are formed on corner portions of the outer lateral edges of extending end surfaces () of the both stabilizers () and R-surfaces (A) are formed on lateral edges () of the C-surfaces (A) on base end sides of the stabilizers ().

Terminal fitting and fluidproof connector provided therewith

A connector has a female terminal () with stabilizers () that contact restricting surfaces () of an edge of a terminal accommodating hole () at a side opposite to a side where insertion paths () are provided, thereby preventing any further insertion of the female terminal () when a female terminal () is inserted in a posture vertically inverted from a proper posture. Posture displacing portions () are provided on the restricting surfaces () of the terminal accommodating hole () and engage the stabilizers () of the female terminal () inserted in the inverted posture to displace extending postures of the stabilizers () to increase engaging margins with the restricting surfaces ().

Connector

A terminal fitting (A) to (D,) is provided with a connecting portion () to be connected with a mating terminal, a wire barrel () to be crimped into connection with an end portion of a conductor () exposed by removing an insulation coating () of a wire () in which the conductor () made up of twisted strands is covered by the insulation coating (), and a restriction () capable of restricting the widening of a leading end side of the conductor () by projecting from a wire barrel () side toward the connecting portion ().
