A voltage tester for testing the cable's withstand voltage with connected connectors.

Abstract

The invention relates to a device for testing the voltage withstand of a cable connected to a connector. The device comprises: a pair of electrode housings; and a control unit configured to apply a start signal to the testing device, which generates a pre-set high voltage, according to the electrical state detected in each electrode housing, which includes: a housing with a portion of the front face opened; a conductive electrode plate mounted on the inside front face of the housing so that it can rotate around its top end; and a switch, mounted inside the housing with a pre-determined gap from the electrode plate, to detect whether the electrode plate rotates due to being pushed into the lower part of the electrode plate. The electrical state is the state between the two electrodes of the switch, and a pre-set high voltage is applied between both electrode plates.
