[0018] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] Reference Figures 1 to 3 As shown, this embodiment provides a voltage detection and error prevention device (hereinafter referred to as the voltage detection and error prevention device) for detecting whether the circuit under test is energized, and the specific circuit under test is a three-phase circuit or a three-phase phase detection hole, such as the phase detection hole of phases A, B, and C of a conventional voltage detector that is being tested.

[0021] like Figure 1 As shown, the voltage detection and error prevention device in this embodiment includes a voltage detector body 9, a flexible three-core electrical connection wire 6, and three electrical connectors 7 for electrically connecting the circuit under test, and the three electrical connectors 7 correspond to the three-phase circuit or the three-phase phase hole respectively.

[0022] like Figure 2 and Figure 3 As shown, the electroscope body 9 includes a control board 3 and an alarm component for warning. One end of the three-core electrical connection cable 6 is electrically connected to the input terminal of the control board 3, and the other end is electrically connected to the corresponding electrical connector 7. The input terminal of the alarm component is electrically connected to the output terminal of the control board 3.

[0023] In this embodiment, the specific electric connector 7 is a banana plug, and the three-core electric connecting wire 6 is a three-core wire. Of course, in other embodiments, the electric connector 7 can also be a clamp.

[0024] As shown in Figure 2 and Figure 3 , the specific alarm assembly includes a buzzer 1 and an indicator light 8, and the input ends of the buzzer 1 and the indicator light 8 are electrically connected to the output ends of the control panel 3. Of course, in other embodiments, the alarm assembly can only have a buzzer 1 or an indicator light 8, or can include other warning devices such as a vibration reminder.

[0025] In operation, the three banana plugs are respectively connected to three-phase power, or the three banana plugs are directly inserted into the A, B, and C phase core holes of a conventional electricity tester for detecting the circuit. Then, when the banana plug contacts a live body, a corresponding electric signal is generated, and is sequentially transmitted to the input end of the control panel 3 through the banana plug and the three-core electric connecting wire 6, and then to the output end of the control panel 3, triggering the buzzer 1 to emit an alarm sound and the indicator light 8 to flash, thereby timely reminding the worker to ensure electrical safety.

[0026] Therefore, through the bendability or flexibility of the three-core electric connecting wire 6 itself, the electric connectors 7 connected to the three-core electric connecting wire 6 can move accordingly following the bending of the three-core electric connecting wire 6, thereby ensuring that the three electric connectors 7 can be flexibly electrically connected to the measured circuit in a limited space, and through the timely reminder of the alarm assembly, the worker can quickly determine whether the measured circuit is live, thereby ensuring the safety of the worker, so that the electricity testing and error prevention device of this embodiment can be used for normal temporary live work in a limited space.

[0027] Of course, in other embodiments, the multi-core electric connecting wire can also use a two-core or four-core or more electric connecting wire, and a corresponding number of electric connectors 7 can be provided.

[0028] In another preferred embodiment, as shown in Figure 2 and Figure 3 , the electricity tester body 9 is provided with two magnets 5 for magnetically fixing the electricity tester body 9.

[0029] In this specific embodiment, as shown in Figure 2 and Figure 3 Figure 2 Figure 3 , the electricity tester body 9 includes a shell, and the specific shell includes an upper shell 2 and a bottom cover 4 that are hinged together, the buzzer 1, the indicator light 8, and the control panel 3 are assembled in the upper shell 2, and the magnets 5 are assembled in the bottom cover 4, i.e., the buzzer 1 and the indicator light 8 are respectively installed on the top of the upper shell 2, the control panel 3 is located in the middle of the shell, and the two magnets 5 are embedded in the bottom cover 4.

[0030] When the two magnets 5 are magnetically adsorbed on the shell corresponding to the measured circuit, the electroscope body 9 can be temporarily magnetically adsorbed on the shell corresponding to the measured circuit, so that at least one hand of the worker can be released, and the worker can further conveniently work in the limited space.

[0031] Although the utility model is specifically shown and introduced in combination with the preferred embodiments, those skilled in the art should understand that various changes can be made to the utility model in form and details without departing from the spirit and scope of the utility model defined in the appended claims, and all are within the protection scope of the utility model.
