[0002] When switch states and control devices leave the factory, they are often not subjected to in-depth component testing due to technical conditions or operating specifications. This means that when manufacturers receive these devices, they mainly rely on routine inspections of model parameters and appearance to assess their quality. However, this inspection method has certain limitations. It can only provide verification of basic information about the device, but cannot reveal potential problems that may exist inside the device.

[0003] During factory testing, it is often found that some devices have quality faults such as black screen, abnormal indication, abnormal output, etc. These problems may be caused by various reasons such as component damage, design defects, improper production process, etc. These faults will not only affect the normal operation of the device, but may also cause the performance of the entire system to decline or even fail, thus bringing unnecessary losses and risks to the user.

[0004] The current state of technology does not have universality for component testing of different switch states and control devices. This means that each time you face different types of switch states and control devices, you need to redesign and adjust the test plan, which undoubtedly increases the difficulty and cost of testing. In addition, due to incomplete testing, some potential problems may not be discovered until after leaving the factory, which further increases the pressure on product maintenance and after-sales service.

[0029] like Figure 2 As shown, a power switch 1, a power indicator light 2, an AC / DC conversion switch 3, an output selection indicator light 4, and a handle 5 are installed on the door of the cabinet body 10, wherein there are several output selection indicator lights 4. The handle 6 is used to open or close the cabinet door.

[0030] like Figure 3 As shown, a plurality of plug-in terminals 6 are provided on the side of the cabinet 10. The present invention adopts the plug-in terminals 6 for docking, so as to realize the universality of testing components of different schemes.

[0031] like Figure 4 As shown, the cabinet 10 is provided with a power input module, an output selection module, a voltage detection module and a device connection module.

[0032] The power input module is connected to the power supply and is used to provide power to the test box. By pressing the power switch 1, the test box will be powered on and the power indicator 2 will be on; by pressing it again, the button will pop up, the test box will be powered off and the power indicator 2 will be off. This function of the power switch 1 allows the user to easily control the power status of the test box, thereby starting or ending the test process.

[0033] The power input module is responsible for converting the external power input into the power form required by the test box. This ensures that the internal circuit of the test box is supplied with stable and pure power. In addition, the power input module may also have some protection functions, such as overvoltage protection, undervoltage protection, overload protection, etc., to prevent the external power abnormality from causing damage to the internal circuit of the test box.

[0034] The power switch 1 controls the on and off of the power supply, while the power input module ensures the stability and purity of the power supply. The two work together to provide reliable power support for the test box and ensure the smooth progress of the test process.

[0035] The output selection module is arranged between the power input module and the voltage detection module, and the voltage detection module is arranged between the output selection module and the device connection module.

[0036] The device connection module is used to connect with the switch status and control device.

[0037] The output selection module includes a power selection module and an indication module.

[0038] The indicator module of the test box displays its status through the output selection indicator light 4. If a fault is detected, the output selection indicator light 4 will flash or light up in a specific way to attract the attention of the tester.

[0039] The output selection module is used to check and inspect whether the output terminal of the heater of the tested component meets the requirements and confirm the output type.

[0040] Then, adjust the position of the plug-in terminal 6 on the test box and the corresponding lead according to the output type to make it consistent with the component under test. The position of the plug-in terminal 6 of the test box and the corresponding wiring are adjustable, which can meet the universal switch status of multiple manufacturers.

[0041] At the bottom of the control panel of the tested component, operate the corresponding function according to the component operation method, and the tested component will heat up and output, and the corresponding heating power indicator of the test box will light up. If there is no abnormality, the heating output function of this component is normal.

[0042] The power selection module is a device used to control and convert the energy form in the power, such as voltage conversion, current control, overvoltage protection, overcurrent protection, short circuit protection and overtemperature protection, etc., to ensure the safety and stability of electronic equipment.

[0043] The indication module includes heating indication, trolley working / testing position, energy storage indication, circuit breaker opening and closing indication and other indications, which are used to display the current switch status and the status of the control device during testing.

[0044] Therefore, the utility model is used for testing the performance of the state of externally purchased switches and control devices.
