Because the industrial plug occupies such an important position in our daily life, as a person who can't tell the difference between industrial plug and ordinary socket, how should we choose such a socket? What we need to pay attention to when using is that I believe this is what buyers and users need to know. For the above-mentioned problems in choosing industrial plug, we can tell us through this article. A socket into which one or more circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits. IP54, that is, 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 4: prevent splashing water from invading, and prevent splashing water from all directions from invading. The power socket has one or more seats into which circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits.When choosing industrial sockets, we need to know the relevant parameters of the surrounding electrical appliances, and select different sockets according to different numerical values, so that they can be used effectively. Because different sockets are different in structure or function, we need to know the relative sizes of electrical appliances effectively to prevent the sockets from malfunctioning. In order to protect the safety of users, we should also choose some sockets. These sockets can protect our own safety, and can effectively input the circuit to the ground, so that we won't get electric shock or leakage when using them. Moreover, it is necessary for us to choose a good socket for testing when using them. Some surface problems can't be avoided when using sockets, and we need to choose a high level of protection when choosing sockets, because it is difficult to ensure that the environment is suitable for sockets when using or testing. Therefore, at present, we must choose more protective sockets. These sockets can face some problematic environments without causing damage and interference, and they are used to a considerable extent, so that there will be no problems in the overall operation. Finally, in order to cooperate with the use of plugs, we need to choose a socket that can prevent the plugs from falling off, so that we can make the plug installation or use the above sockets not easily fall off, which makes the whole circuit very harmonious. The overall safety and reliability can be greatly improved. In our current use environment, we need to use it effectively and reasonably. In this environment, we need to use and test it effectively. Using the above socket in the whole will make the industrial plug more effectively maintain the whole circuit system. When we use or check the equipment, we need to operate according to such steps and methods, make reasonable choices according to the surrounding environment, and choose the appropriate socket size and model according to the specifications of the products and the size of the circuits, which can effectively prevent the use failure of the products.
