In some embodiments, the main body 100 includes a housing 103 and a rubber core 104 disposed within the housing 103 for fixing the lines 102. Specifically, inserting the multimeter probes into any two holes 101 forms a detection loop, eliminating the need to disassemble the circuit 102 and improving detection efficiency; the multimeter reading determines whether the circuit 102 is abnormal. Using this scheme, each circuit 102 is equipped with two resistors 1021, forming a voltage divider detection circuit to prevent overload damage to the equipment during testing; the button 1025's linkage to the spring contact terminal 1023 enables quick wiring, suitable for frequent testing scenarios; the independent circuit layout 102 facilitates fault location and repair.

[0058] In some embodiments, two resistors 1021 are connected by welding, forming a welding position 1021a; the welding position 1021a is located between the two resistors 1021. In some embodiments, two resistors 1021 in each line 102 are arranged side by side, then the welding position 1021a is located between the two side-by-side resistors 1021.

With the above solution, the plastic insulating part 1026 can isolate the bending position 1021b from the resistor 1021 to avoid damage to the resistor 1021 due to vibration or compression, and ensure the stability of the detection circuit.

[0059] In some embodiments, the end of the terminal 1022 away from the resistor 1021 is provided with a slot 1022a, forming an elastic contact portion 1022b. In some embodiments, the elastic contact portion 1022b is a cylindrical structure with an axial slot 1022a, and the elastic contact portion 1022b cooperates with the hole 101. By adopting the above solution, the elastic contact portion 1022b is designed as a cylindrical structure with an axial slot 1022a, which can ensure tight contact with the multimeter probe and reduce the contact resistance 1021.
