Generally, when purchasing plugs and sockets, what problems should be paid attention to? First of all, it is undoubtedly a regular manufacturer, and secondly, whether there is a manufacturer’s logo, and whether the product logo is complete. These are important indicators for testing product quality. Talk about this issue in detail.
1. You must choose a regular factory, supermarket or specialty store, choose branded products, and choose corresponding (matching) products according to the power of the electrical appliances used, such as: air conditioners, high-power showers and other products should use 16A plugs and sockets, other small For household appliances with high power, you can choose a 10A plug socket. For example, when purchasing a 16A plug power cord, you need to see whether the wire square size is 1.5 square or more. If the wire is less than 1.5 square, it is easy to wire when using high-power electrical products. The copper wire heats up and the PVC outer skin becomes soft, causing problems such as electrical burnout or circuit short-circuiting.
2. It is necessary to see if the product logo is complete, whether there is a manufacturer’s trademark, whether there is a local country’s safety certification mark (for example, in the Chinese market, there must be a CCC mark), if there is no mark on the plug and wire product, then this plug The product must be a fake product, and the quality of the product will not be guaranteed.
3. Check the qualification certificate and the inspection report issued by the statutory department for plug products. If the converter product is not included in the compulsory certification, you should check the inspection report issued by the statutory inspection agency when purchasing, or check whether the file number on the plug is valid or not.
4. Perform a simple insertion experiment on the plug product. The plug should be in good contact after being inserted into the socket. There should be no feeling of looseness, and it can be pulled out without too much force. It is inevitable that although some products have passed the factory inspection, they have been transported after leaving the factory. Will damage the plug inserts, test before buying, to reduce a lot of unnecessary losses in the future.
5. Never buy plugs with rotatable pins or artificially change the shape of the plugs. The plugs that have changed their shape must pass CCC certification. Otherwise, they are absolutely unsafe plug products that are easily punctured by high-voltage electricity. Use two high-power electrical appliances on one socket at the same time; if the temperature of the plug socket or the power cord is too high or there is a fire, stop using it and replace it.
