Claims

[Scope of utility model registration request]

A connector provided on the outside of the housing to lead out a plurality of lines under test to the outside of the housing, and each of the lines under test led out through a connector connected to the connector to one pole of a reference voltage source in sequence. A switch circuit for switching connection, a circuit for sequentially switching and operating the switch circuits, and a signal when a current flowing between the other pole of the reference voltage and the line selected by the switch circuit exceeds a predetermined value. a current detector that outputs a signal, a circuit that determines whether or not a signal is output from the current detector each time the switching operation circuit switches, and displays the determination result by the determination circuit in correspondence with the line. An insulation defect detection device comprising means for detecting insulation defects.
