Poor quality of plugs and sockets and converters is an important cause of electrical fires. The quality problems of small plugs, sockets, and converters will pose serious harm to the personal and property safety of consumers. Therefore, consumers should pay attention to the safety of products when purchasing plugs, sockets, converters, and switches. The main performance indicators affecting their safety are:
Sign
The sign is an important basis for instructing people to properly install, use and repair, and is an extremely important safety standard for ensuring the safety of personal and property. Plug and socket products should be marked with rated current, rated voltage, power supply properties, etc. in obvious positions. In addition, the converter (converter refers to a mobile electrical accessory with only one plug part and one or more socket parts combined). The product uses the "MAX (or maximum)" symbol to indicate the rated current / or power, To guide users to avoid overloading. The logo or symbol should be durable and legible. Silkscreen and paper stickers that can be easily erased should not be used.
Rating
The rating is the most basic electrical interchange matching parameter to ensure the normal, safe, and suitable use of the plug and socket, the converter, and the connected electrical appliance. For example, the rated current of the converter must not exceed the rating of the plug part. Otherwise, the user may choose to use the electrical appliance according to the rated current of the socket, the overcurrent of the plug is heated and the danger is generated; the minimum rating of the converter with the fuse and the overload protector should be equal to the marked on the fuse and the overload protector. Rating. Otherwise, product damage may occur.
size
Dimensions are an important technical requirement related to the safe use of plugs and sockets and whether the universal interchangeability requirements are met to avoid miss-insertion. Unqualified size can affect the user's use or cause hidden troubles such as poor contact, miss-insertion, etc., even if the equipment is damaged, and the fire and electric shock will occur.
Protection against electric shock
Anti-shock protection is a key safety indicator to ensure that the plug and socket, the converter under normal conditions, and even some accidents, will not cause electric shock to users and others. When the plug and the socket are fully or partially inserted, the l...
