A receptacle includes a signal terminal, a ground terminal, and a signal terminal. A second portion of the ground terminal is distanced from a first portion of the signal terminal in an extension direction. A third portion of the signal terminal is distanced from the first portion of the signal terminal in the extension direction.

Receptacle, printed wiring board, and electronic device

A receptacle structure includes a housing structure, a terminal insulating board, a first terminal and a second terminal. The housing structure is configured to be mounted on a printed wiring board and to accommodate a plug. The terminal insulating board includes a top face and a bottom face that is opposite to the top face. The terminal insulating board is disposed inside the housing structure with the bottom face facing towards the printed wiring board. The first terminal is connected to the printed wiring board via the first rear connection part and to the terminal insulating board. The second terminal is connected to the printed wiring board via the first front connection part and to the terminal insulating board. The first front connection part has a width narrower than the first rear connection part and is connected to the printed wiring board away from the first rear connection part.

Receptacle structure, printed wiring board structure, and electronic device

A plasma display device capable of reducing an electromagnetic interference wave due to a driving current flowing in a plasma display panel is provided. The plasma display device includes a plasma display panel having electrodes that are parallel to each other, a driver circuit board for applying a voltage to the electrodes, a chassis conductor holding the plasma display panel and to which a ground of the driver circuit board is connected, and a first additional conductor plate provided to the chassis conductor via an insulating layer and to which grounds of at least one circuit board in circuit boards other than the driver circuit board are attached.

Plasma display device

Each of a pair of signal terminals (Tand T) includes a signal terminal link portion (u) that links a first signal terminal end portion (u) and a second signal terminal end portion (u). A ground terminal (T) includes a ground terminal link portion (t) that links a first ground terminal end portion (t) and a second ground terminal end portion (t). The ground terminal link portion (t) is wired between the signal terminal link portion (u) and a mounting surface (A) from the opposite side of the mounting surface (A) relative to the signal terminal link portion (u).
