A first sheet metal is provided with slits. Elastic pieces having flat shapes are each formed between the slits adjacent to each other, and both ends of each of the elastic pieces are connected with both ends of an adjacent one of the elastic pieces. A second sheet metal is provided with protrusions each of which is protruded toward a corresponding one of the elastic pieces.

An electrical connector is capable of performing stable inspection without affecting an extraction force of a connector engagement portion. The electrical connector includes a housing having an electrical insulation property, an internal terminal held by the housing, and an external terminal held by the housing, with the external terminal to be electrically connected to a ground. The external terminal includes a fitting portion having a first engagement wall portion at one side and having a second engagement wall portion at the other side in a plan view from a connector insertion/extraction direction. A first engagement portion is formed at the first engagement wall portion, and a second engagement portion is formed at the second engagement wall portion.

The invention is applicable to the technical field of connectors, and in particular, relates to a terminal structure for a high-speed data transmission connector and a connector thereof. The terminal structure for a high-speed data transmission connector comprises an upper row terminal and a lower row terminal respectively assembled at an upper end and a lower end of an insulating body of the high-speed data transmission connector, and electrically connected to a PCB motherboard of the high-speed data transmission connector, the upper row terminal comprising a front-end terminal and a rear-end terminal connected to each other, and the terminal structure further comprises: a first anti-resonance module comprising a first conducting member disposed on the front-end terminal; and a second anti-resonance module comprising a second conducting member disposed on the rear-end terminal; wherein an exterior angle at connection of the front-end terminal and the rear-end terminal is from 55° to 80°. In view of this, the application improves anti-resonance effect of the terminal structure and the connector.

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.

In a connector assembly in which a connector that includes a ground terminal including a plate portion and a mating connector that includes a mating ground terminal including a mating plate portion are fitted to each other, the plate portion and the mating plate portion have plate surfaces that are parallel to each other, the plate portion is composed of a pair of U-shaped portions that are adjacent to each other, the mating plate portion is shaped to have a pair of projection portions forming a concave portion therebetween, the projection portions formed in a pair are respectively positioned in U shapes of the pair of U-shaped portions, each of leg portions of the mutually-adjacent U shapes in the pair of U-shaped portions is positioned in the concave portion, and protrusion portions of the leg portions are respectively in contact with the projection portions.

The present disclosure provides a connector that comprises a housing and wafers. The housing comprises a top wall and a bottom wall separated from each other in a mounting direction. The wafers are mated to the housing in a mating direction and supported by the housing. A first wafer is configured to be limited in the mounting direction. A second wafer is configured to be limited in the mating direction. A possible benefit from a match between a limiting block of the first wafer and a limiting groove of the housing and a match between the limiting block of the first wafer and a limiting opening of the housing is that the first wafer is less easy to move between the top wall and the bottom wall of the housing along the mounting direction and can be more firmly supported by the housing.
