[0022] The multimeter 25 is connected with two test wires 33, which are used to contact the power line and the body of the electric vehicle respectively to detect leakage; Both test wires 33 are connected to an elastic current wire 32, which is made of a highly conductive material to ensure accurate measurement. The ends of the elastic current wires 32 are connected to a test probe 31 to accurately contact the test point. The outer wall of the protective housing 21 is provided with storage grooves 27 on both sides for storing the test probe 31 and the elastic current line 32. The inside of the storage groove 27 is evenly connected with a buckle hoops 28 for fixing the test probe 31 to prevent loosening and falling off, thereby ensuring convenient and safe use. In this embodiment, by providing a close fit between the protective housing 21 and the cover 23, the intrusion of external dust and moisture is effectively prevented, and the built-in multimeter 25 and its connecting parts are fully protected, thereby extending the service life; at the same time, the portable design of the protective housing 21 makes the device easy to carry and suitable for a variety of environments, especially leakage detection in outdoor operations and emergency situations, which greatly improves the efficiency and safety of use. Example

[0023] See also Figure 1-Figure 4 On the basis of the first embodiment, it is further obtained that the specific structure of the test probe 31 includes an insulating handle 311, a metal probe 312 and a metal contact cap 316. The surface of the insulating handle 311 is provided with an anti-slip texture to improve the holding stability; the tip of the metal probe 312 is specially treated to enhance the penetration and ensure accurate contact; the metal contact cap 316 is made of high-quality conductive material to ensure stable signal transmission; The metal probe 312 is installed at the front end of the insulating handle 311.

The resistor 313 is used to limit the current and protect the neon lamp 314 from damage. The neon lamp 314 is composed of a small glass body and two electrodes. The interior is filled with neon gas. When leakage is detected, the neon lamp 314 will light up and send out a warning signal. The metal contact cap 316 is tightly embedded in the end of the insulating handle 311. A micro spring 315 is connected between the neon lamp 314 and the metal contact cap 316 to press the resistor 313 and the neon lamp 314 to prevent shaking, so as to ensure that all components are stable and reliable during the measurement process. In this embodiment, by setting the linkage mechanism of the neon lamp 314 and the resistor 313, the sensitivity and accuracy of leakage detection are further improved, ensuring that a warning can be quickly issued in a complex environment to ensure the safety of the user.

[0026] When in use, the test probe 31 is taken out from the buckle hoop 28 provided in the storage slot, inserted into the test point of the electric vehicle to be tested, the insulating handle 311 is gripped, and the power button 26 is turned on. The current is limited by the resistor 313 and flows to the neon lamp 314. If there is a leakage, the light will light up to warn, and the current will flow back to the multimeter 25 along the elastic current line 32. The display screen will immediately display the leakage value, which is convenient for the user to quickly judge the leakage situation and take safety measures in time. The whole detection process is simple and efficient, which greatly improves the convenience and safety of operation. It is especially suitable for rapid detection in complex environments and effectively prevents electrical accidents.
