Patent ID: 8444444

Claim:
A connector, comprising: a housing having at least one press-fit hole with a substantially rectangular cross-section perpendicular to a penetration direction; and at least one terminal fitting inserted into the press-fit hole, the terminal fitting having at least one press-fit portion with a substantially rectangular cross-section perpendicular to an inserting direction into the press-fit hole, the press-fit portion having two substantially flat side surfaces substantially parallel to each other and disposed in surface contact with inner surfaces of the press-fit hole in a fluid-tight manner, the press-fit portion further having front and rear surfaces aligned substantially parallel to one another and extending between the side surfaces, the press-fit portion being formed so that front and rear convex bulges are formed respectively on the front and rear surfaces at positions spaced apart along the inserting direction, the front and rear bulges bulging in directions parallel to the two flat side surfaces and extending over entire areas of the front and rear surfaces in directions connecting the two flat side surfaces, a rear concave area formed on the rear surface at a position opposite the front convex bulge and a front concave area formed on the front surface at a position opposite the rear convex bulge, wherein the front and rear convex bulges press the inner surfaces of the press-fit hole in a fluid-tight manner.
