Abstract

PURPOSE:To allow a single power supply to work with inspection of a circuit board and facilitate the wiring design by incorporating a signal level converting circuit into a connector, which is to connect a plurality of circuit boards operating at different signal levels. CONSTITUTION:A signal level converting integrated circuit 2 is mounted in the case 3 of a connector 1 and connected to terminals 4, 5. A through hole 12 in a circuit board 10 is connected with the terminal 4 of the connector 1, while a through hole 13 in a printed circuit board with the other terminal 5. Thereby the circuit boards 10, 11 convert the signal level with each other through the circuit 2 and make handover/reception with each other. Thus the circuit boards 10, 11 handle only one signal level, so that the testing machine for circuit boards is inspectable with a single power supply, wherein no care shall be taken for the capacity type bond, which facilitates the wiring design.
