This ＂universal socket＂ has been banned for 6 years, which may cause a fire!

　　　　　　　 Recently, the fire department issued a safety reminder, and the "universal socket" still in use at home was quickly thrown away and replaced with a new national standard socket.

　　　　　　　 "It’s really scary. I just put the plug on it and the socket actually sparks." Speaking of the thrilling scene, Mr. Zhan of Guangzhou has a lingering fear. The socket that sparks is a new universal socket he bought from the Internet recently.

　　　　　　　 It is understood that the three-hole "universal socket" has been widely used in daily life because it is compatible with all kinds of plugs. However, this kind of socket has low safety factor and is easy to cause fire accidents. The country has banned the use since 2010. Now that the ban has been implemented for six years, the reporter’s investigation found that many citizens still use "universal sockets" in their homes and workplaces, and they also have their shadows in the market.

　　　　　　　 Why should this "universal socket" be banned?

　　　　　　　 There are many plugs compatible with the universal socket (such as plugs compatible with British standard, American standard and European standard), so the jack is large. After the metal tabs in the socket are plugged and unplugged by plugs of different shapes and specifications, the reed with poor elasticity is easy to deform or damage, resulting in too small contact area or poor contact between the metal tabs of the socket and the electrical plug, and the resistance is increased, which leads to overheating of the contact tabs and fire accidents. Accordingly, the General Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Administration Committee issued the "new national standard for sockets", which clearly pointed out that universal sockets that are prone to fire are unqualified products.

　　　　　　　 On June 1, 2010, the General Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Administration jointly issued the "Plug and socket for household and similar purposes Part 2: Special requirements for converters", which explicitly prohibited the production of this universal hole socket.

　　　　　　　 Enterprises with low prices continue to produce and sell.

　　　　　　　 The price of this kind of patch panel is cheap, generally only 10 yuan’s money, and the expensive one is 40 yuan, which is at least twice as cheap as the new five-hole socket of the same type. Six years later, some enterprises still secretly produce universal sockets, which are still available in the market. Hardware stores, building materials markets, convenience stores and online stores buy sockets, which is the flood of unqualified sockets.

　　　　　　　 The reporter visited several large supermarkets in Zhenjiang City, Jiangsu Province, and found that there was no trace of universal sockets on the shelves. The sockets of many brands on sale were all in the new national standard. One of the brands also clearly made the logo of "true national standard socket" on the outer packaging. "The universal socket has long been sold out and eliminated, and the supermarkets are all in line with the latest national standards." The staff said. Similarly, in several building materials markets in urban areas, although the brands of sockets on sale are different, their designs all meet the new national standard.

　　　　　　　 However, in several convenience stores near Jiangsu University, reporters found a variety of banned universal sockets. Its "block head" is relatively large, and the wiring length ranges from 2.5 meters to 9.5 meters, with two price points in 65 yuan and 72 yuan. The store said that the old and new sockets are only designed differently to meet different needs, and the quality is no problem. During the interview, several citizens at the scene said that there is no concept about the old and new standards, so it is convenient and easy to use.

　　　　　　　 There are still many people buying and using it.

　　　　　　　 Due to the continuous production and sales of enterprises and businesses, many consumers do not know that the country has banned "universal sockets" and continue to use them, and many of them have been recruited.

　　　　　　　 In the survey, some netizens reported that they had universal sockets at home. "They were all purchased a few years ago. They were not specially selected at that time and have been used until now." Some netizens also reported that there are many universal sockets in their office, which were purchased by the unit a few years ago, mainly for connecting computers, and they didn’t realize there was a problem.

△ Burned socket

△ Burn out the plug

　　　　　　　 What kind of socket meets the new regulations?

　　　　　　　 The reporter learned that the three-phase jack and the two-phase jack of the new national standard socket are separated, and there are five holes, one for one use. The words "produced according to GB2099.3-2008 standard" are marked on the package. The new standard sockets basically have safety pieces, that is, there are plastic pieces in the holes, which ensure the safety of children and are not easy to get an electric shock.

　　　　　　　 Pay attention to these when choosing and using sockets.

　　　　　　　 ① Choose famous brand products in formal places.

　　　　　　　 ② Lightly pull the power cord to see if it is firm, and repeatedly press the switch to see if it switches freely.

　　　　　　　 (3) weigh. There are many copper wires, thick copper sheets and tight plastic shells in the sockets that meet the national standards, so the weight is heavy, while the unqualified sockets will obviously feel much lighter by cutting corners.

　　　　　　　 4 listen to the sound. You can try to press the socket switch several times, and the qualified socket can be opened and closed freely with clear sound, while the unqualified socket is stiff and easy to get stuck.

　　　　　　　 ⑤ Try to feel. Qualified sockets not only have moderate and elastic plug-in feel for each hole, but also have the same plug-in feel for each jack. The plug-in force for unqualified sockets is too loose or too tight, with poor elasticity and easy loosening, and each hole can obviously feel different feel.

　　　　　　　 ⑥ Look at hardness. The power cord of the qualified socket feels soft and hard, and the connection with the socket is solid and reliable, while the power cord of the unqualified socket feels soft and the connection with the socket is not firm, so it is easy to pull off.

　　　　　　　 ⑦ When in use, it is best not to share a socket with high-power appliances such as refrigerators, air conditioners and televisions. (Source: Legal Evening News, Guangzhou Daily, Jiangsu, China Net, etc.)
