摘要:
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.

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.

摘要:
An apparatus for testing plug-in type integrated circuits by applying a potential across their input and output terminals, utilizing a socket board with a plurality of sockets bored therein to receive respective input and output terminals of an integrated circuit. A pair of first and second groups of fixed contacts are located in the socket board, arranged in two concentric circles enclosing the sockets. Each fixed contact in each group is individually connected to one of the sockets through a conductor. A pair of coaxial first and second moving contact pins is rotatably disposed below the socket board. The first contact pin rotates to follow the first circle while sequentially contacting the contacts of the first group. The second contact pin follows the second circle, making sequential contact with the fixed contacts of the second group. It is so arranged that, when both contact pins are brought into contact with a selected pair of contacts from the two groups, one contact pin connects an input terminal while the other contact pin connects an output terminal, or vice versa, of the integrated circuit mounted on the socket board. In doing so, the contact pins pass current across the output and input terminals for a test.
