The multimeter 25 is equipped with a power button 26, which passes through the cover plate 23 and is exposed on the surface of the cover plate 23 for easy operation. Since the multimeter 25 is a product disclosed in the prior art, its detailed structure will not be described here.

[0026] The multimeter 25 is connected to two test leads 33, which are used to contact the electric vehicle's power cord and the vehicle body respectively to detect leakage.

[0027] Both test leads 33 are connected to elastic current wires 32, which are made of highly conductive materials to ensure accurate measurement. The ends of the elastic current wires 32 are connected to test probes 31 for precise contact with the detection points.

[0028] The outer walls of the protective housing 21 are provided with storage slots 27 on both sides for storing the test probe 31 and the elastic current wire 32.

[0029] In this embodiment, by setting the protective shell 21 and the cover plate 23 to fit tightly together, external dust and moisture are effectively prevented from entering, and the built-in multimeter 25 and its connecting parts are fully protected, extending its service life. At the same time, the portable design of the protective shell 21 makes the device easy to carry and suitable for various environments, especially for outdoor operations and leakage detection in emergency situations, which greatly improves the efficiency and safety of use.
