Device for checking the withstand voltage of a cable to which a connector is connected

A device for checking withstand voltage of a cable, comprising:

• a pair of electrode boxes;
• and
• a control block configured to apply a driving 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 movable plate mounted on an inner front side of the housing in such a way that it is rotatable around its top end;
• and
• a static plate fixed to an inner front side of the housing so as to be vertically coplanar with the movable plate by leaving a gap with a lower end of the movable plate,
• wherein the electrical state is either of electrical disconnection and short circuit between the movable plate and the static plate according to whether a conductive object is inserted into the gap, and the movable plates or the static plates of the pair of electrode boxes are electrically connected to the output ports respectively, and
• wherein a lower part of the movable plate and an upper part of the static plate bend into the housing to form a curved surface, respectively.
