In order to meet the needs of use, it is generally necessary to test the internal circuit of the product. However, the existing testing equipment cannot adapt to the testing of electronic products with different interfaces. Different products need to use different testing equipment, and the testing cost is relatively high. In addition, when testing under power, there is a safety hazard of electric shock because the operator needs to hold the testing equipment in close contact with the product interface.

The product to be tested is connected to the detection end. The detection end is integrated with a Stäubli socket and an AC-Box socket, Wallbox 2.0 socket, Sungrow socket, FoxESS socket, or Huawei socket electrically connected to the Stäubli socket. The detection end is connected to the control end via the Stäubli socket. The control end comprises:

[0005] A receiving module, connected to the detection end, for receiving a status signal of the product to be tested after being connected to the detection end;

[0006] An MCU control module is connected to the receiving module and is used to determine whether the internal circuit of the product to be tested is on or off according to the status signal;

[0007] The switch module is connected to the MCU control module and is used to output a control signal through a button and output it to the MCU control module.

[0008] Furthermore, the Stäubli socket, AC-Box socket, Wallbox 2.0 socket, Sungrow socket, FoxESS socket, and Huawei socket all have a first live wire L1, a second live wire L2, a third live wire L3, a neutral wire N, and a ground wire PE;

[0009] Furthermore, it also includes an audio-visual alarm module, which is connected to the MCU control module and is used to provide corresponding audio-visual prompts for the on / off status of the internal circuit of the product to be tested according to the signal output by the MCU control module; the audio-visual alarm module includes a buzzer and an LED light;

[0010] Furthermore, it also includes a display module connected to the MCU control module, for displaying corresponding information according to the signal output by the MCU control module to indicate whether the internal circuit of the product to be tested is open or disconnected; the display module adopts a display;

[0012] Furthermore, the chip model of the MCU control module is STM32F103RET6.

[0013] The beneficial effect of the present invention is that the detection end is integrated with multiple types of interfaces, so it can adapt to electronic products with different interfaces for detection. During detection, the control signal is output to the MCU module through the switch module, and then the status signal is fed back to the MCU module through the receiving module, so that it can be judged whether the internal circuit of the product to be tested is open or disconnected. The operation is convenient, the detection cost is low, the risk of electric shock is avoided, the safety is high, and it has good economic value. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figures 1 to 3As shown, the utility model provides a circuit continuity detection device, which includes a detection terminal 1 and a control terminal 2. A product to be tested 3 is connected to the detection terminal 1. The detection terminal 1 is integrated with a Stäubli socket 15 and an AC-Box socket 4, a Wallbox 2.0 socket 5, a Sungrow socket 6, a FoxESS socket 7, and a Huawei socket 8 electrically connected to the Stäubli socket 15. The detection terminal 1 is connected to the control terminal 2 through the Stäubli socket 15. The Stäubli socket, the AC-Box socket 4, the Wallbox 2.0 socket 5, the Sungrow socket 6, the FoxESS socket 7, and the Huawei socket 8 all have a first live wire L1, a second live wire L2, a third live wire L3, a neutral wire N, and a ground wire PE. The control terminal 2 includes:

[0019] The receiving module 9 is connected to the detection terminal 1 and is used to receive the status signal of the product 3 to be tested after being connected to the detection terminal 1;

[0020] The MCU control module 10 is connected to the receiving module 9 and is used to determine whether the internal circuit of the product under test 3 is on or off according to the status signal; the chip model of the MCU control module 10 is STM32F103RET6;

[0021] The switch module 11 is connected to the MCU control module 10 and is used to output a control signal through a button and output it to the MCU control module 10;

[0022] The sound and light alarm module 12 is connected to the MCU control module 10 and is used to provide corresponding sound and light prompts for the on / off status of the internal circuit of the product 3 to be tested according to the signal output by the MCU control module 10;

[0023] The display module 13 is connected to the MCU control module 10 and is used to display corresponding information according to the signal output by the MCU control module 10 to indicate whether the internal circuit of the product under test 3 is open or disconnected;

[0024] The power supply module 14 is used to supply power to the receiving module 9 , the switch module 11 , the MCU control module 10 , the sound and light alarm module 12 , and the display module 13 .

[0025] The sound and light alarm module 12 includes a buzzer and an LED light; the display module 13 adopts a display.

[0026] In the present invention, during testing, the tester only needs to connect the test terminal 1 to the control terminal 2 via the Stäubli socket 15. Depending on the product to be tested, such as a Huawei inverter, the tester connects the Huawei socket 8 to the corresponding interface of the Huawei inverter. By pressing the button of the switch module 11, the control terminal 2 can be activated. Then, the receiving module 9 feeds back the received status signal to the MCU control module 10. If the MCU control module 10 can receive the status signal, the internal circuit of the product to be tested 3 is in a connected state. If it cannot receive the signal, it is in a disconnected state. This facilitates the continuity test of the internal circuit of products with different interfaces, is convenient and safe to operate, and has low testing costs.
