Abstract: A circuit board is arranged on an end face of a lens barrel on a lens mount side and installed with an electronic circuit device, a plurality of connection terminals which are arranged in an electrically insulating state in the lens mount and serve to connect the electronic circuit device on the circuit board with an electronic circuit device inside a camera body, and a wiring member is for connecting the plurality of connection terminals with the circuit board, where the wiring member is provided with a ground connection section which is connected to a ground pattern of the circuit board and also electrically connected to a connection terminal that is to be a ground terminal among the plurality of connection terminals, and an extended wiring pattern is for electrically grounding the ground connection section on a metal portion of the lens mount.

Abstract: 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.

Abstract: 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.

Abstract: Each of a pair of signal terminals (TC+ and TC?) includes a signal terminal link portion (uCON) that links a first signal terminal end portion (u1) and a second signal terminal end portion (u2). A ground terminal (TGC) includes a ground terminal link portion (tCON) that links a first ground terminal end portion (t1) and a second ground terminal end portion (t2). The ground terminal link portion (tCON) is wired between the signal terminal link portion (uCON) and a mounting surface (11A) from the opposite side of the mounting surface (11A) relative to the signal terminal link portion (uCON).

Abstract: A plasma display device including a plasma display panel having electrodes through which a driving current flows; a chassis conductor holding the plasma display panel and provided with a return circuit of the driving current; a conductive case enclosing the plasma display panel and the chassis conductor; and a binding portion for binding the chassis conductor and the conductive case to each other and having a connection state different depending upon a frequency of flowing current. The binding portion has a connection state in which an amount of flowing current is less than a half of that in a short-circuited state and a connection state in which the amount is not less than a half of that in a short-circuited state.
