For some production enterprises set the national mandatory safety standards in disregard, wantonly production of non-national standard mobile power outlet (commonly known as wiring board, hereinafter referred to as the socket), resulting in unsafe socket flooding the market, May 6, Shenzhen, Beijing, Tianjin, Shanghai, Xi'an, Kunming and other 37 provinces and cities of the Consumers Association (Consumer Council, Consumer Protection Committee) and the Chinese consumer newspaper, jointly issued consumer warning: non-national standard outlet unsafe, wide open eyes risk consumers in the purchase of the socket , Be sure to buy a new national standard socket, do not buy unsafe million hole socket and two-core socket.

China prohibits the production of holes with easy hole

Million hole socket, that is, the jack can be compatible with two poles or three poles, and even the British standard, American standard, the European standard such as non-daily use of the plug socket, but such jacks larger jack, socket patch and electrical Plug contact area is too small, easy to make contact pieces overheating lead to the occurrence of fire accidents.

June 1, 2010, by the State Administration of Quality Supervision and the National Standardization Management Committee jointly issued the "household and similar use plug socket Part 2: the special requirements of the converter" (referred to as: the new national standard) began to enforce, explicitly prohibit the production Universal hole socket. The new GB requires the production of two-pole and three-pole jacks in separate combinations (commonly known as the new five-hole socket) socket, this socket plug and socket contact area is larger, closer contact, reducing the risk of electric shock.

In addition, since China's first time in 1996 to develop power outlet standards, it is clear that the two-core socket failed. Two-core socket from the appearance point of view is easier to distinguish, all the plugs have three-pole jack, but the socket itself comes with only two plugs on the plug, are two-core problem socket. This type of socket is missing a ground wire, in the course of the use, once the electrical parts of an electrical insulation within the damaged, the current will be covered with the entire electrical surface, because the current can not be imported through the two-core socket underground,
