There are many aspects in the use of industrial plugs and sockets, which are not only suitable for one direction, but also cause some unnatural artificial hidden dangers to a great extent. The losses caused by the use of small industrial plugs in different places and directions will be enormous and incalculable. We must carefully understand how to use industrial plugs and plugs, and at this point, we must ensure safe use, so as to reasonably launch production and creation. Embedded socket is embedded in an integrated communication cabinet, which provides DC basic power for communication and data equipment in the same cabinet. It has certain universality at the same time. 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. Before using industrial plugs and sockets, we should know their rated voltage and current. We should not blindly choose a low-voltage place in a high-voltage environment. On the contrary, we should read the instruction manual, and we need to know whether it has a certificate of safe use and qualification, know and understand the selection of industrial plugs and sockets, and know its own performance and rated size. We should also pay attention to the fact that different sockets and plugs are produced in different countries, and the specifications of products vary from country to country. We should have a clear scope, what we can use, and we should not use them at will. We should also know and be clear about the size. Appropriate size can be used correctly, and reasonable use methods can make industrial plugs and sockets play their own functions. In the use of industrial plugs and sockets, a simple test should be carried out to see if a good contact relationship can be achieved between the plugs and sockets. When we carry out this test, we must not exert too much force to avoid causing wear between the plugs and sockets, so that the plugs and sockets can not be closed after they are damaged. If signs of looseness are found during the test, we must replace them in advance or carry out maintenance treatment, and we cannot pretend not to see them and ignore their placement. Although people often forget this point, it is really necessary for the use of industrial plugs and sockets, and don't change the shape of plugs and sockets at will, because it is like this. If we twist or change its shape at will, it will damage its internal parts, and make us prone to short circuit or leakage when using it, which will have certain hidden dangers to ourselves. It is necessary for us to remember not to change the shape of plugs and sockets. When using an industrial socket, do not put the power plug in a damp or dark place, because it is easy to leak electricity. The high water content in the surrounding environment is also a major potential safety hazard, because when it is turned on by itself, if the surrounding environment is very humid and the industrial plug and socket are not strong at this time, it is easy to leak water and change the whole environment, thus affecting our own safety. The industrial plug and socket should not be too old in use, and the aged plug and socket should be replaced in time to avoid the damage caused by the aging of the whole circuit and the influence on the whole production chain.
