IEC connectors have grounding function?

Yes, some types of IEC connectors do have grounding function. In the IEC standard, some connector designs include grounding pins or grounding connection points to ensure safe connection and operation of devices.
IEC connectors with grounding function typically include three main pins or connection points:
Line: Used for transmitting current.
Neutral: Used for circuit return, transmitting current back to the power source.
Ground: Used to connect the device casing to the ground, providing grounding protection for the device.
Through grounding connection, the device casing and internal circuits can safely conduct electricity to the ground, preventing electric shock and reducing the risk of static electricity accumulation. This is crucial for protecting users and devices from electric shock and damage, especially in the event of a fault.
Although not all IEC connectors have grounding function, it is very common to use connectors with grounding function in situations where higher safety and protection are required. When choosing connectors, especially for devices that require grounding protection, it is important to ensure that the selected connectors comply with relevant safety standards.
