The safe use of the power cord plug

Plugs and sockets, switches electrical fire caused by poor quality is an important cause. Small plugs and sockets, converters will have the majority of the quality of personal and property safety of consumers pose a serious hazard. Therefore, consumers in the purchase of plug sockets, switches, switch, should consider the safety of products, which might affect their safety performance indicators are the following:
Mark
Signs are indicative of people correctly, use and maintenance of an important basis to ensure personal and property safety of the very important safety standard content. Plug and socket products should clearly mark the location of the rated current, voltage, power properties. In addition, the converter (converter is only part of a plug and socket parts of one or more of the combined mobile electrical accessories) products use "MAX (or maximum)" symbol to mark the rated current / or power, to guide the user to avoid overload. Signs or symbols should be durable, clearly visible. You should not use the screen can be easily erased and paper sign posted.
Rating
Rating is to ensure that the plug sockets, switches and electrical appliances are connected to normal, safe, with the use of interchangeable with basic electrical parameters. Such as: the converter rated current shall not exceed the rating of the plug part. Otherwise, it may cause the user based on matching electrical appliances rated socket when the plug is too hot and dangerous currents; with fuses, overload protection of the converter should be equal to the minimum rating of fuses, overload protection on the mark rating. Otherwise, the product may be damaged.
Size
Size is related to whether the converter plug and socket and the safe use, meets the general requirements in order to avoid incorrect insertion interchangeability is an important technical requirements. Size will affect the users fail or produce bad, incorrect insertion and other risks, ranging from the damage, it will produce heavy fire and electric shock.
Protection against electric shock
Protection against electric shock is to ensure that the plug socket converter in normal use, and even some unexpected circumstances, users and others will not cause electric shock accident of a key safety indicators. When the plug and socket insert timely whole or in part, the plug should not touch live parts; plug any other latch bolt is in reach of state, should not be charged with the outlet plug cover plug together. With protective door plug socket converter should be able to prevent the pole or probe inserted.
Structure
Plug socket set components should be flexible enough to ensure that the plug pins have enough contact pressure. Plug should be corrosion-resistant and wear-resistant cover, plugs and sockets to plug together to ensure good contact part; plug pins should be locked and can not rotate, otherwise it will affect the performance and the resulting insecurity inserted; converter with soft-line fixtures, to ensure soft line fixed, able to withstand the normal tension and torque, etc.; plug and socket plug timely, should be inserted between the basic surface closely together in order to prevent electric shock accidents.
Power cord
Power cord should be of sufficient cross-sectional area, to ensure that the power cord will not cause heat damage to insulation caused by short circuit, fire, leakage, caused the accident. Such as: common 250V, 10A converter power line cross-sectional area greater than or equal to 0.75mm2.
Mechanical strength
Plugs and sockets should have sufficient mechanical strength to withstand installation and use the drop generated in the process, impact, and compression caused by a variety of mechanical stress; with protective doors should be able to prevent the pole into the socket.
Heat and fire
High-temperature insulating materials of all kinds of great influence on performance, insulation materials in high temperature conditions, its structure and properties will be in the nature of the changes, which determine the reliability of the materials used, some materials at high temperatures will gradually soften, mechanical strength decreases, which will affect the quality and use of plugs and sockets in safety. In addition, plugs and sockets should be a fire-retardant insulation performance. Otherwise, the product will be in case of fire use the situation as out of control. Understanding of the safety performance of the plug socket in the purchase and use, the following points to ensure your family and property:
A selection: Select the regular shopping malls, supermarkets or stores, select brand products; according to the use of electrical power to select the appropriate (matching) of products, such as: air conditioner, power showers and other products should be used 16A plug and socket, and other small power The appliance can use a 10A plug and socket.
Second look: look at the product sign are complete to see whether the CCC mark.
Three examinations: inspection certificate and statutory inspection report issued by the department. Such as conversion products not included in the mandatory certification, you should check when purchasing a statutory inspection agency issued the inspection report.
Four test: a simple plug together experimental, plug in the socket after good contact, no feeling loose and not too hard to pull out.
Five NOTE: Do not buy a plug or bolt can be rotated to change the shape of the plug man; do not a power socket at the same time using two large appliances; found the power cord plug and socket, or ignition temperature is too high or there, should stop use and replace.
