Abstract

PURPOSE:To detect and display the place on a printed circuit substrate where a connector is pulled out, easily and surely, by using two sets of connection pins between a pair of the connectors as pins for a detection signal line connected to a detection circuit. CONSTITUTION:Two sets of connection pins of a connector (b) of a printed substrate 1 and a connector 6' to be connected thereto in the position of 180 deg. with each other are used as pins for a detection signal line and are connected and short-circuited to each other by a connection signal line C'. The detection signal through the signal line C of the substrate (a) is thus detected through the line C' in a line C'' only in the case when a pair of the connectors b, b' are connected without pull-out. The place of the printed circuit substrate where there is the pull-out of the connector is detected and displayed surely with the above- mentioned constitution.

能であった。In conventional copiers, the wire harness for sending signals from the printed wiring board to other lamps, motors, etc. is connected via a connector on the printed wiring board (connector between the printed wiring board and the wire harness). In this case, if the nectar on the printed circuit board comes out, the copier will display a malfunction and stop, but the user will not be able to determine the cause of the malfunction.
It was not possible to determine whether it was a disconnected connector on the printed I/S board or some other mechanical or electrical failure.

? installed connector b and signal harness d' to each device
Connector connection signal lines e and C' and connector connection signal line C' are provided respectively to connector b' connected to connector b', and when the connectors are connected normally? I key, connector connection signal lines c and c' are short-circuited by c'. - When the connector is connected normally and the power is on, the connector connection signal is output from f4) 11 c and passed through C'. Since the signal flows to C", the copying machine can operate normally only when the connector connection signal is detected at C". However, as shown in Figure 2, if connector b' is disconnected from b, connector connection signal lines C and c' will be cut off and no connector connection signal will be detected.In other words, disconnection of the connector will be detected. . When a disconnected connector is detected, the cause of the problem is immediately displayed on the display panel of the control panel on the electrophotography machine, for example in alphabetical order.

きない場合が起こり得るからである。In Figure 1 and Figure 2, the pin positions for detecting disconnection of the connector are shown as two sets at one end of the pin row of the connector. It is more preferable to have one set at each end. That is, if one end of the connector (1111 where the pin for detecting connector disconnection is located) is completely connected, but the other end is incomplete, disconnection of the connector may not be detected.

方法・手段である。Similarly, in the case of a circular connector, it is preferable to use two rows of pins located 180@f) from each other with respect to the center of the connector. It can be applied not only to disconnecting the connector between the wire harness and the wire harness. In this case, two wire harnesses are added, and each rItcll and a connector constitute a closed circuit of these two wires. By placing a connector connection signal line on these m, the device is electrically open to 0%, which makes it possible to detect and report any disconnection between each device and the wire harness in the same way as above. That's 4t! This is an effective method/means when the impact on sweetfish is large or dangerous.
