The operator can connect the first conductive terminal 11 and the second conductive terminal 12 with different devices according to the test requirement. For example, when the electrical safety testing device 100 is used for a discharge test, as shown in fig. 4, the two first conductive terminals 11 are respectively connected to an oscilloscope, and the two second conductive terminals 12 are respectively connected to a high voltage system, that is, the electrical safety testing device 100 is connected in parallel to the high voltage system, and the oscilloscope detects the voltage of the high voltage system to perform an active and passive discharge test. For another example, when the electrical safety testing apparatus 100 is used to perform the analog insulation test, as shown in fig. 5, one end of the resistor box is connected to one of the first conductive terminals 11, the other end of the resistor box is connected to the vehicle body ground, and the two second conductive terminals 12 are respectively connected to the high voltage system. It should be noted that the high voltage system of the electric vehicle generally includes a high voltage distribution box and a power battery which are connected to each other.

In the process of continuously carrying out the discharge test and the simulation insulation test, in order to prevent an operator from mistakenly connecting the resistor box with the two first conductive terminals 11 at the same time. The utility model discloses an electricity safety test equipment 100 has set up fly leaf 20 on its body 10, through the change of fly leaf 20 positions, realizes the switching of electricity safety test equipment 100 function, avoids the misconnection to lead to the emergence of potential safety hazard.

Referring to fig. 2 and 4, when the movable plate 20 of the electrical safety testing apparatus 100 is in the first position, at this time, the two first conductive terminals 11 and the two second conductive terminals 12 are both exposed outside the housing 30, that is, the first conductive terminals 11 and the second conductive terminals 12 are exposed on the surface of the body 10, so that the first conductive terminals 11 are conveniently connected to an oscilloscope, and the second conductive terminals 12 are connected to a high voltage system.
