When using low-voltage plugs and sockets, we must pay attention to safe use, otherwise, some serious accidents, fires, etc. may be caused, and serious injuries and property losses will be caused to a great extent. NEMA wiring device must be as small as possible in order to realize frequent commutation, but also to realize braking during commutation and acceleration after commutation. Therefore, it is necessary to adopt rapid commutation device and smart braking device. A socket into which one or more circuit wires can be inserted, through which various wires can be inserted to facilitate connection with other circuits. IP54, i.e. dust prevention is level 5: dust intrusion cannot be completely prevented, but the amount of dust intrusion will not affect the normal operation of the product; Waterproof grade is Grade 4: prevent splashing water from intruding and prevent splashing water from all directions from intruding. I will introduce several aspects of safe use of low-voltage plugs and sockets. Of course, all the low-voltage plugs and sockets we use are qualified, and safe use is one of the most important factors. Here, I will take you to know which performance factors in the low-voltage plug and socket will affect the safety of the whole low-voltage plug and socket. The first point is mechanical strength. A good low-voltage plug and socket should have strong mechanical strength, so that the low-voltage plug and socket can have strong compression resistance in the long-term use process, and can bear the mechanical stress caused by various external drops, impacts, etc., so that the low-voltage plug and socket can be used stably and safely for a long time. The second point is that the cross-sectional area of the power cord of the low-voltage plug and socket should meet the standard conditions, so as to avoid to a great extent some problems such as short circuit and electric leakage caused by the non-standard cross-sectional area of the power cord of the low-voltage plug and socket during use, and ensure the safe use of the low-voltage plug and socket. The third point is that the rating should meet the standard range, so that the product parameters that can be used on the low-voltage plug and socket in the use process are matched, and it can be used normally and safely. Do not use low-voltage plugs and sockets that do not meet the rating. Do not use excessively high rated low-voltage plugs and sockets, which do not meet the rated values. This may cause overheating, damage to low-voltage plugs and sockets and some products, and cause very serious property damage and electricity leakage. In fact, the fourth point is very similar to the third point, that is, the size of the low-voltage plugs and sockets used must meet the standards for safe use; otherwise, forcibly using some low-voltage plugs and sockets that do not meet the standards for safe use will cause hidden dangers such as poor contact, seriously damage equipment, and even cause dangerous accidents such as electric shock and fire alarm. The fifth point is to use the structure of low-voltage plug and socket safely. The components of low-voltage plug and socket should have good elasticity, so that they can have better resistance to contact pressure. The plugs between low-voltage plug and socket can be closer. Under the condition of not affecting the performance of low-voltage plug and socket, the normal operation of low-voltage plug and socket can be ensured without causing some accidents such as electric shock. The last point is that low-voltage plugs and sockets need to be protected against electric shock to ensure that they will not cause some more dangerous contact conditions in case of failure. Therefore, protection against electric shock is a very important safety index in the production process of low-voltage plugs and sockets.
