Abstract

PURPOSE: To avoid the breakdown caused by the shock current occurring at the connector connection time as well as by the output short in case two circuits are connected to each other by allowing the signal transfer between those circuits in a fixed time after the connector is actually connected.
CONSTITUTION: Terminals b1 and bn of receptor 13 are connected to the earth each, and terminal a1 and an are connected to coincidence circuit 19. Accordingly, if the plug is connected to receptor 11 and 13 each at time t1, the output of coincidence circuit 19 is changed to a low level in case the connection is performed satisfactorily. The output of circuit 19 is then delayed by time T through delay circuit 21, and the coincidence with the signal before delay is detected at coincidence circuit 22 to give the transfer permission signal. The transfer permission signal is applied to transfer circuit 23 and display control circuit 26 to start the transfer along with the display. In such way, the transfer is allowed in a fixed time after connection of the connector, thus avoiding the shock current.
