Socket has been playing an insignificant role in our life. Although they are almost everywhere, although TVs, computers, refrigerators... All household items with the word "electricity" should be "connected with their hearts and hands", it seems that people have long turned a blind eye to them, and never thought that a small socket would make any big noise. But recently, the State Bureau of technical supervision conducted a quality supervision and inspection of plug and socket products, which has made people nervous about safe use

socket has always played an insignificant role in our life. Although they are almost everywhere, although TVs, computers, refrigerators... All household items with the word "electricity" should be "connected with their hearts and hands", it seems that people have long turned a blind eye to them, and never thought that a small socket would make any big noise. But recently, a quality supervision and inspection of plug and socket products by the State Bureau of technical supervision has tightened the string of safe use of sockets

in the first quarter of 1999, the National Bureau of quality and technical supervision organized the national household electrical appliances quality supervision and testing center to conduct national supervision and random inspection on the quality of household appliances and similar plugs and sockets, mainly including 36 kinds of plugs and sockets and converters from 34 enterprises in Beijing, Shanghai, Tianjin, Guangdong, Zhejiang and other major cities across the country? Commonly known as patch panel? The qualified rate only accounts for 30%! And the unqualified items focus on important safety indicators such as electric shock protection and temperature rise, which has great hidden dangers. Thinking of a series of electrical fires in recent years, people couldn't help but sweat. According to the results of this spot check, the plug and socket products produced by large and medium-sized enterprises are of good quality

the products produced by the two large enterprises in this spot check are all qualified, and the sampling qualification rate has reached 100%; Ten products of medium-sized enterprises were randomly selected, and eight products were qualified, with a qualified rate of 80%; 24 kinds of products produced by small enterprises were randomly selected, and 13 kinds were qualified, with a sampling qualification rate of 54.2%. The qualified rate of product spot check of large and medium-sized enterprises is significantly higher than that of small enterprises. This spot check revealed many problems in the converter products. After the implementation of gb2099.1-1996 standard, many mobile socket and converter manufacturers failed to organize production according to the requirements of the new standard. In addition, there are also individual enterprises with weak technical strength, rough manufacturing in the production process, and Jerry building. The copper strip used as the socket is too thin, so that the conductor and copper strip are seriously heated during the temperature rise test, causing the temperature rise to be too high. This product has the hidden danger of causing fire

according to the statistics of the public security department, among the fire accidents that have occurred in China in the past ten years, the fire caused by electrical faults such as short circuit, overload and poor contact of wires has always ranked first among all kinds of fires, accounting for about 28% of the total number of fires every year. In 1997 alone, there were 22719 electrical and gas fires in the country! Therefore, the elimination of fire hazards from the socket link has been paid more and more attention. Experts believe that in order to fundamentally solve this problem, we must have "strict" requirements for socket shell materials. In order to prevent potential electric shock, the shell material of the socket is not allowed to use metal raw materials, and if the insulating material should meet the best requirements of flame retardancy? Don't burn in case of open fire?, The cost of raw materials will increase by 4-5 times! This will give a heavy blow to the enterprises that used to take advantage of this huge difference to occupy the market at a low price. In addition, lightning accidents are also frequent in China every year. Experts call on citizens to improve their awareness of lightning protection, and socket products with lightning protection function can be selected when necessary

modern electrical products have created a living space for fast-paced modern people to envy the ancients, and the socket is a detail that can not be ignored to decorate this space. At present, the quality of plug and socket products circulating in the market is mixed. In view of the existing problems, the State Administration of quality and technical supervision will cooperate with the enforcement of the new national standard and strengthen the publicity of the national standard for plug and socket. Please pay attention to the following issues when purchasing:

1. The product appearance logo

the new national standard has made clear provisions on the rated current, which is divided into three levels: 6a, 10a and 16A. Non standard products such as 13A and 15A are not allowed to be sold, let alone the phenomenon of marking 10a and 16A at the same time. In addition, when choosing a socket, consumers should also check whether the logo of the plug and socket are consistent. If the rated current of the plug is less than the logo of the socket, do not buy it. This is an unqualified dangerous product. Another point is that the product package should have a detailed manufacturer's address and telephone number. Only the mobile phone number or no address, fake production license and electrician certification, 9000 license are all three no products

2. Whether the jack is wrongly inserted

generally, if the socket is too close, it may be wrongly inserted; Second, the design of the multi-purpose Jack itself is unreasonable, and there is a three pin misinsertion problem

3. Materials of socket products

first, the internal wiring and socket of the socket should be made of materials that meet the specifications. If the internal wiring is too thin or the socket is too thin, it will lead to too high temperature rise and fire; Second, the shell should be flame-retardant, so as to prevent fire hazards from inside to outside

in addition, relevant experts remind consumers that when choosing plug and socket products, they should also pay attention to whether the products have a production license or "CCEE" safety certification mark, and try to choose the products of large and medium-sized enterprises, and do not unilaterally pursue low prices
