A good power outlet can help the operation of the whole equipment, and its performance will affect the normal operation of the whole equipment. The power socket has one or more seats into which circuit wiring can be inserted, through which various wiring can be inserted, so as to facilitate connection with other circuits. Industrial plugs are suitable for industrial use, and are generally divided into 3-core, 4-core, 5-core, etc. The current is generally divided into 16A, 32A, 63A, 125A, 250A, 420A, etc., and the protection level can be divided into IP44 and IP67, which are relatively conventional. Generally, it is used together with industrial sockets and connectors. 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. The shell of the power socket is made of imported plastic, which can reach 90℃ without deformation under normal conditions. In this case, how to choose a suitable power socket will be discussed from several aspects. The first thing to consider is where to use the power outlet and where to connect it. Using the connection between occasions and things, these two points can help us find out the types of power outlets. Whether it is used indoors, outdoors, in harsh environment, in water or only outdoors, it will affect the sealing performance of the socket. Then we should consider environmental problems, such as temperature, humidity, sunshine and other environmental conditions, so we should not only understand the current environmental factors, but also all the environmental problems that may be encountered in the future are the environmental requirements for power outlets. There are other environmental conditions that need to be considered, such as storage conditions, the storage environment and storage time of power outlets, and so on. On the issue of environmental conditions, it is also necessary to understand the requirements of shock and vibration and some requirements of production environment. The requirement of electrical appliances is a very important point in choosing power outlets. What kind of voltage and current does the power outlet have, and whether the power outlet can be applied to the power you need to consider. There are some other electrical conditions, such as allowable change of resistance, millivolt drop, maximum current and voltage, which need to be considered in the electrical requirements. In addition to the performance of the above selected power outlets, we should also observe some material problems of the power outlets. If the pin is an imported brass product, it has good plug function and anti-corrosion performance. Its overcurrent and bearing pressure have reached the national advanced level, so you can use it with confidence. China has compulsory certification for power outlets, so do not buy products without 3C certification, instead, go to professional manufacturers, choose some well-known brands, and pay special attention to those manufacturers who have passed the national supervision and sampling inspection for many times. When selecting the power socket, make sure that the power socket matches the rating of the power socket. We should not choose two completely unrelated connections. The rated current of the plug should not be less than the rated current of the socket. The selected rated current must be an industrial plug that is greater than or equal to the industrial plug. If the two connections are reversed, the accident may be very unsafe. The above is what you need to pay attention to when purchasing industrial plugs. When purchasing integrated points, you can save time for solving problems in the future. If you encounter something you don't understand when buying, you can go directly to the factory, and the factory will have professional technicians to answer your questions.
