1. A device for checking withstand voltage of a cable, comprising:
a pair of electrode boxes; and
a control block configured to apply a start signal to a test instrument, which drives output ports thereof with a preset voltage, in accordance with an electrical state detected in each of the pair of electrode boxes,
wherein each of the pair of electrode boxes comprises:
a housing configured such that at least a part of a front side thereof is open;
a conductive electrode plate mounted on an inner front side of the housing in such a way that it is rotatable around its top end; and
a switch unit, mounted inside the housing with a predetermined gap from the electrode plate, configured to detect a state in which the electrode plate is rotated while a lower part of the electrode plate is pushed inward,
wherein the electrical state is an electrical state between both terminals of the switch unit, and the electrode plates of the pair of electrode boxes are electrically connected to the output ports respectively, and
wherein the switch unit is configured such that the electrical state between both terminals is changed by a force applied by the electrode plate or an accessory member coupled to the electrode plate.
