Factors affecting the safety of power cords

　　The poor quality of power cord plugs, sockets and converters is one of the main reasons for electrical fire alarms. The quality problems of small plugs, sockets and converters will pose serious risks to the personal and wealth safety of consumers. Therefore, when consumers buy plugs, sockets, converters, and switches, they should focus on the safety of the products, and the following functional goals are the first to affect their safety:

　　mark

　　The 　　 mark is the main basis for instructing people to accurately install, use and maintain, and is an extremely important safety standard content to ensure the safety of personal wealth. Plug and socket products should be marked with extra current, extra voltage, power source, etc. in a distinct position. In addition, converters (converters refer to mobile electrical accessories that only have one plug part and one or more socket parts combined together) products should be marked with the "MAX (or maximum)" symbol to indicate additional current/or power , To guide users to prevent overloading. Marks or symbols should be durable and legible. You should not use silk screens and paper labels that can be erased casually.

　　Extra value

　　Extra value is the most fundamental electrical exchange common parameter that guarantees the normal, safe, and common use of plugs, sockets, converters and connected electrical appliances. For example: the extra current of the converter must not be greater than the extra value of the plug. Otherwise, it can form a risk that when users choose electrical appliances according to the extra current of the socket, the plug will have a fever due to overcurrent; the minimum extra value of the converter with a fuse and an overload maintenance device should be equal to the mark on the fuse and overload maintenance device Additional value. Otherwise, product damage can appear.

　　size

　　Size is a major technical requirement related to whether plugs and sockets and converters can be used safely, and whether they can meet general interchangeability requirements to prevent accidental penetration. Substandard size of the three-core 10A suffix power cord will affect the user's use or cause potential hazards such as poor contact and accidental penetration. From the light to the equipment, it can cause fire and electric shock.

　　Anti-shock maintenance

　　Electric shock prevention maintenance is a key safety goal to ensure that plugs, sockets and converters under normal operating conditions, and even some unexpected conditions, will not form a key safety goal for users and others to get an electric shock. When the plug is fully or partially connected to the socket, the live parts of the plug should not be touched; any plug of the plug should not be able to engage with the live socket of the socket when the other pins are in an accessible form. Plug sockets and converters with maintenance doors should be able to avoid single pole or probe penetration.
