Abstract

In a connector assembly in which a first connector and a second connector are fitted to each other, a first shell, which has a rectangular frame-like shape and serves as an outer shell of the first connector, includes curved portions on upper ends of respective sides of the rectangle, and a second shell, which has a rectangular frame-like shape and serves as an outer shell of the second connector, includes convex portions, which are elongated along respective sides to be slender, on outer surfaces on the sides of the rectangle. The curved portions and the convex portions are positioned so that the curved portions and the convex portions are partially overlapped with each other. The convex portions are in contact with the first shell through the entire lengths, and the curved portions are in contact with the second shell through the entire lengths.

Claims (38)

1. A connector assembly in which a first connector and a second connector are respectively mounted on opposing surfaces of a first board and a second board, the first board and the second board being opposed to each other, and are fitted to each other, wherein

a first shell, the first shell having a rectangular frame-like shape and being made of a metal plate and serving as an outer shell of the first connector, includes a curved portion on an upper end of each side in a rectangle of the rectangular frame-like shape, the upper end facing the second board, the curved portion having a shape that is bent to protrude toward an inside of a rectangular frame of the rectangular frame-like shape and then reversely bent to protrude toward an outside of the rectangular frame,

a second shell, the second shell having a rectangular frame-like shape and being made of a metal plate and serving as an outer shell of the second connector, includes a convex portion on an outer surface on a side of a rectangle of the rectangular frame-like shape, the convex portion being elongated along the side to be slender,

the curved portion and the convex portion are positioned so that the curved portion and the convex portion are not completely overlapped but are partially overlapped with each other and complementarily form the rectangular frame-like shape when viewed from a fitting direction between the first connector and the second connector,

the second shell is housed in the first shell so that the convex portion is positioned closer to the first board than the curved portion, and

the convex portion is in contact with the first shell through an entire length thereof, and the curved portion is in contact with the second shell through an entire length thereof.

2. The connector assembly according to claim 1 , wherein

there is a cutout on the upper end of the first shell, and

a depth of the cutout is set not to impair contact between the convex portion and the first shell on a position, on which the cutout is positioned, in a side direction of the rectangle.

3. The connector assembly according to claim 2 , wherein

a part between two pieces of the cutouts on the upper end of the first shell is a carrier cut portion.

4. The connector assembly according to claim 1 , wherein

a first ground pattern having a frame-like shape is formed on the first board, and the first shell and the first ground pattern are soldered and connected to each other through an entire circumference by a first soldering part provided along the first ground pattern, and

a second ground pattern having a frame-like shape is formed on the second board, and the second shell and the second ground pattern are soldered and connected to each other through an entire circumference by a second soldering part provided along the second ground pattern.

5. The connector assembly according to claim 2 , wherein

6. The connector assembly according to claim 3 , wherein

7. The connector assembly according to claim 4 , wherein

there is a cutout on a lower end of the first shell, the lower end facing the first board, and the cutout on the lower end is closed by the first soldering part.

8. The connector assembly according to claim 5 , wherein

there is a cutout on a lower end of the first shell, the lower end facing the first board, and the cutout on the lower end is closed by the first soldering part.

9. The connector assembly according to claim 6 , wherein

there is a cutout on a lower end of the first shell, the lower end facing the first board, and the cutout on the lower end is closed by the first soldering part.

10. The connector assembly according to claim 4 , wherein
