止回路。In an automatic test device that performs a dielectric strength test of a high-voltage part of a device under test, a connection part between the device under test and the automatic test device draws out a grounding wire and one or more high-voltage wires on the device under test side. Short-circuit the test connection socket on the device under test side and the ground wire of the terminal under test to one pole of the output of the dielectric strength tester, and short-circuit the high voltage wire of the terminal under test to one to connect the insulation. It is connected to the connecting plug on the automatic tester side for connecting to the other pole of the strength tester, and has multiple terminals for connection detection to detect that the connecting plug receiver and the connecting plug are connected. The connection detection terminal is provided in the connection plug holder and the connection plug, and when applying a high voltage from the automatic test equipment side to the device under test side, connect the connection detection terminal to a grounding wire drawn out from the device under test side. However, when applying a low voltage that is not grounded to the connection detection terminal for connection detection without applying a high voltage,
The Hakama connection detection terminal is configured to be separated from the grounding wire.
- A circuit for preventing high and low pressure from coming into contact with each other for automatic testing equipment.
